Undergraduate medical education requires ongoing improvement in order to keep pace with the changing demands of twenty-first century medical practice. Problem-based learning is increasingly being adopted in medical schools worldwide. We review its application in the specialty of ENT, and we present our experience of using this approach combined with more traditional methods. We introduced problem-based learning techniques into the ENT course taught to fifth-year medical students at Al-Ahsa College of Medicine, King Faisal University, Saudi Arabia. As a result, the teaching schedule included both clinical and theoretical activities. Six clinical teaching days were allowed for history-taking, examination techniques and clinical scenario discussion. Case scenarios were discussed in small group teaching sessions. Conventional methods were employed to teach audiology and ENT radiology (one three-hour session each); a three-hour simulation laboratory session and three-hour student presentation were also scheduled. In addition, students attended out-patient clinics for three days, and used multimedia facilities to learn about various otolaryngology diseases (in another three-hour session). This input was supplemented with didactic teaching in the form of 16 instructional lectures per semester (one hour per week). From our teaching experience, we believe that the application of problem-based learning to ENT teaching has resulted in a substantial increase in students' knowledge. Furthermore, students have given encouraging feedback on their experience of combined problem-based learning and conventional teaching methods.

The Mission Management Office at the Jet Propulsion Laboratory was tasked with coordinating the relay of data between multiple spacecraft at Mars in support of the Mars Exploration Rover Missions in early 2004. The confluence of three orbiters (Mars Global Surveyor, Mars Odyssey, and Mars Express), two rovers (Spirit and Opportunity), and one lander (Beagle 2) has provided a challenging operational scenario that required careful coordination between missions to provide the necessary support and to avoid potential interference during simultaneous relay sessions. As these coordination efforts progressed, several important lessons were learned that should be applied to future Mars relay activities.

The purpose of this study was to compare two pedagogical methods, active learning and passive instruction, to determine which is more useful in helping students to achieve the learning outcomes in a one-hour research skills instructional session. Two groups of high school students attended an instructional session to learn about consumer health resources and strategies to enhance their searching skills. The first group received passive instruction, and the second engaged in active learning. We assessed both groups' learning using 2 methods with differing complexity. A total of 59 students attended the instructional sessions (passive instruction, n=28; active learning, n=31). We found that the active learning group scored more favorably in four assessment categories. Active learning may help students engage with and develop a meaningful understanding of several resources in a single session. Moreover, when using a complex teaching strategy, librarians should be mindful to gauge learning using an equally complex assessment method.

Skipper, Mads; Musaeus, Peter; Nøhr, Susanne Backman

2016-02-02

This study aimed to analyse and redesign the outpatient clinic in a paediatric department. The study was a joint collaboration with the doctors of the department (paediatric residents and specialists) using the Change Laboratory intervention method as a means to model and implement change in the outpatient clinic. This study was motivated by a perceived failure to integrate the activities of the outpatient clinic, patient care and training of residents. The ultimate goal of the intervention was to create improved care for patients through resident learning and development. We combined the Change Laboratory intervention with an already established innovative process for residents, 3-h meetings. The Change Laboratory intervention method consists of a well-defined theory (Cultural-historical activity theory) and concrete actions where participants construct a new theoretical model of the activity, which in this case was paediatric doctors' workplace learning modelled in order to improve medical social practice. The notion of expansive learning was used during the intervention in conjunction with thematic analysis of data in order to fuel the process of analysis and intervention. The activity system of the outpatient clinic can meaningfully be analysed in terms of the objects of patient care and training residents. The Change Laboratory sessions resulted in a joint action plan for the outpatient clinic structured around three themes: (1) Before: Preparation, expectations, and introduction; (2) During: Structural context and resources; (3) After: Follow-up and feedback. The participants found the Change Laboratory method to be a successful way of sharing reflections on how to optimise the organisation of work and training with patient care in mind. The Change Laboratory approach outlined in this study succeeded to change practices and to help medical doctors redesigning their work. Participating doctors must be motivated to uncover inherent contradictions in their medical activity systems of which care and learning are both part. Facilitators must be willing to spend time analysing both historical paediatric practice, current data on practice, and steer clear of organisational issues that might hamper a transformative learning environment. To ensure long-term success, economical and organisational resources, participant buy-in and department leadership support play a major role.

To describe the development of a cadaver-based educational program and report our residents' assessment of the new program. An anatomy-based educational program was developed using fresh frozen cadavers to teach surgical anatomy and operative skills to general surgery (GS) trainees. Residents were asked to complete a voluntary, anonymous survey evaluating perceptions of the program (6 questions formulated on a 5-point Likert scale) and comparing cadaver sessions to other types of learning (4 rank order questions). Large university teaching hospital. Medical students, residents, and faculty members were participants in the cadaver programs. Only GS residents were asked to complete the survey. Since its implementation, 150 residents of all levels participated in 13 sessions. A total of 40 surveys were returned for a response rate of 89%. Overall, respondents held a positive view of the cadaver sessions and believed them to be useful for learning anatomy (94% agree or strongly agree), learning the steps of an operation (76% agree or strongly agree), and increasing confidence in doing an operation (53% agree or strongly agree). Trainees wanted to have more sessions (87% agree or strongly agree), and believed they would spend free time in the cadaver laboratory (58% agree or strongly agree). Compared with other learning modalities, cadaver sessions were ranked first for learning surgical anatomy, followed by textbooks, simulators, web sites, animate laboratories, and lectures. Respondents also ranked cadaver sessions first for increasing confidence in performing a procedure and for learning the steps of an operation. Cost of cadavers represented the major expense of the program. Fresh cadaver dissections represent a solution to the challenges of efficient, safe, and effective general surgery education. Residents have a positive attitude toward these teaching sessions and found them to be more effective than other learning modalities. Copyright © 2012 Association of Program Directors in Surgery.

Thornton, Ronald

2010-10-01

Physics education research has shown that learning environments that engage students and allow them to take an active part in their learning can lead to large conceptual gains compared to traditional instruction. Examples of successful curricula and methods include Peer Instruction, Just in Time Teaching, RealTime Physics, Workshop Physics, Scale-Up, and Interactive Lecture Demonstrations (ILDs). An active learning environment is often difficult to achieve in lecture sessions. This presentation will demonstrate the use of sequences of Interactive Lecture Demonstrations (ILDs) that use real experiments often involving real-time data collection and display combined with student interaction to create an active learning environment in large or small lecture classes. Interactive lecture demonstrations will be done in the area of mechanics using real-time motion probes and the Visualizer. A video tape of students involved in interactive lecture demonstrations will be shown. The results of a number of research studies at various institutions (including international) to measure the effectiveness of ILDs and guided inquiry conceptual laboratories will be presented.

Studying Different Tasks of Implicit Learning across Multiple Test Sessions Conducted on the Web

PubMed Central

Sævland, Werner; Norman, Elisabeth

2016-01-01

Implicit learning is usually studied through individual performance on a single task, with the most common tasks being the Serial Reaction Time (SRT) task, the Dynamic System Control (DSC) task, and Artificial Grammar Learning (AGL). Few attempts have been made to compare performance across different implicit learning tasks within the same study. The current study was designed to explore the relationship between performance on the DSC Sugar factory task and the Alternating Serial Reaction Time (ASRT) task. We also addressed another limitation of traditional implicit learning experiments, namely that implicit learning is usually studied in laboratory settings over a restricted time span lasting for less than an hour. In everyday situations, implicit learning is assumed to involve a gradual accumulation of knowledge across several learning episodes over a longer time span. One way to increase the ecological validity of implicit learning experiments could be to present the learning material repeatedly across shorter test sessions. This can most easily be done by using a web-based setup in which participants can access the material from home. We therefore created an online web-based system for measuring implicit learning that could be administered in either single or multiple sessions. Participants (n = 66) were assigned to either a single session or a multiple session condition. Learning occurred on both tasks, and awareness measures suggested that acquired knowledge was not fully conscious on either of the tasks. Learning and the degree of conscious awareness of the learned regularities were compared across conditions and tasks. On the DSC task, performance was not affected by whether learning had taken place in one or over multiple sessions. On the ASRT task, RT improvement across blocks was larger in the multiple-session condition. Learning in the two tasks was not related. PMID:27375512

To provide an interactive, non-supplement based complementary and alternative medicine (CAM) session in a self-care therapeutics class and to evaluate the effect of the session on pharmacy students' perceptions and knowledge of CAM. Second professional year pharmacy students enrolled in a required 3-credit course titled Self-Care Therapeutics participated in an active learning session on CAM. Students physically engaged in 5 separate active learning CAM sessions including massage therapy, Tai Chi, yoga, progressive muscle relaxation, and Reiki. Students were assessed on both knowledge and perception of CAM. Concept mastery was assessed using a written examination and individual readiness assurance tests (iRAT) and team readiness assurance tests (tRAT). Perception of CAM was measured using both a presession and a postsession survey. Participating in an intensive, active learning CAM session provided an opportunity to increase students' knowledge of CAM and an effective strategy for providing the learner with the experience to better envision incorporation into patient therapies.

To evaluate the relative acceptability of the flipped classroom approach compared with traditional didactics for in-house teaching in emergency medicine. Our department changed its learning model from a 'standard' lecture-based model to a 'flipped classroom' model. The 'flipped classroom' included provided pre-session learning objectives and resources before each 2 h weekly session. In-session activities emphasised active learning strategies and knowledge application. Feedback was sought from all medical staff regarding the acceptability of the new approach using an online anonymous cross-sectional qualitative survey. Feedback was received from 49/57 (86%) medical staff. Ninety-eight per cent (48/49) of respondents preferred the flipped classroom over the traditional approach. Aspects of the flipped classroom learners liked most included case-based discussion, interaction with peers, application of knowledge, self-directed learning and small-group learning. Barriers to pre-session learning include work commitments, 'life', perceived lack of time, family commitments, exam preparation and high volume of learning materials. Reported motivational factors promoting pre-session learning include formal assessment, participation requirements, more time, less material, more clinical relevance and/or more interesting material. Case studies and 'hands-on' activities were perceived to be the most useful in-session activities. The flipped classroom shows promise as an acceptable approach to in-house emergency medicine teaching. © 2015 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

Extinction of Cocaine Seeking Requires a Window of Infralimbic Pyramidal Neuron Activity after Unreinforced Lever Presses

2017-01-01

The infralimbic cortex (IL) mediates extinction learning and the active suppression of cocaine-seeking behavior. However, the precise temporal relationship among IL activity, lever pressing, and extinction learning is unclear. To address this issue, we used activity-guided optogenetics in male Sprague Dawley rats to silence IL pyramidal neurons optically for 20 s immediately after unreinforced lever presses during early extinction training after cocaine self-administration. Optical inhibition of the IL increased active lever pressing during shortened extinction sessions, but did not alter the retention of the extinction learning as assessed in ensuing extinction sessions with no optical inhibition. During subsequent cued reinstatement sessions, rats that had previously received optical inhibition during the extinction sessions showed increased cocaine-seeking behavior. These findings appeared to be specific to inhibition during the post-lever press period because IL inhibition given in a noncontingent, pseudorandom manner during extinction sessions did not produce the same effects. Illumination alone (i.e., with no opsin expression) and food-seeking control experiments also failed to produce the same effects. In another experiment, IL inhibition after lever presses during cued reinstatement sessions increased cocaine seeking during those sessions. Finally, inhibition of the prelimbic cortex immediately after unreinforced lever presses during shortened extinction sessions decreased lever pressing during these sessions, but had no effect on subsequent reinstatement. These results indicate that IL activity immediately after unreinforced lever presses is necessary for normal extinction of cocaine seeking, suggesting that critical encoding of the new contingencies between a lever press and a cocaine reward occurs during that period. SIGNIFICANCE STATEMENT The infralimbic cortex (IL) contributes to the extinction of cocaine-seeking behavior, but the precise relationship among IL activity, lever pressing during extinction, and extinction learning has not been elucidated using traditional methods. Using a closed-loop optogenetic approach, we found that selective inhibition of the IL immediately after unreinforced lever pressing impaired within-session extinction learning and promoted the subsequent cued reinstatement of cocaine seeking. These studies suggest that IL activity immediately after the instrumental response during extinction learning of cocaine seeking encodes information required for such learning and that altering such activity produces long-lasting changes in subsequent measures of cocaine craving/relapse.

MO-C-9A-01: Effective Medical Physics Educational Activities: Models and Methods

DOE Office of Scientific and Technical Information (OSTI.GOV)

Sprawls, P

Medical physics is learned in a combination of activities including classroom sessions, individual study, small-group collaborative problem solving, and direct experience in the laboratory or clinical environment. Each type of learning activity is characterized by its effectiveness in producing the desired knowledge for the learner and the cost in terms of resources and human effort required providing it. While learning and teaching is a human activity, modern technology provides a variety of tools that can be used to enhance human performance. The class or conference room is the common setting for educational sessions in both academic institutions and continuing educationmore » conferences and programs such as those sponsored by the AAPM. A major value of a class/conference room program is efficiency by bringing a group of learners together to share in a common learning experience under the guidance of one or more experienced learning facilitators (lecturers or presenters). A major challenge is that the class/conference room is separated from the real world of medical physics. The design of an educational activity needs to take into consideration the desired outcomes with respect to what the learners should be able to do. The distinction is that of being able to apply the knowledge to perform specific physics functions rather than just knowing and being able to recall facts, and perhaps do well on written examinations. These are different types of knowledge structures within the human brain and distinctly different learning activities to develop each. Much of medical physics education, especially at the post-graduate and continuing education level, is for the purpose of enhancing the ability of physicists and other related professionals to perform applied procedures and tasks and requires specific types of knowledge.In this session we will analyze various learning activity models, the values and limitations of each, and how they can be used in medical physics education. An example we will use is optimizing CT image quality and dose which is an important topic for medical physicists, radiologists and residents, along with technologists. The knowledge structure for this is best developed by a combination of learning activities including class/conference discussions, individual study and review, and direct observation and interaction in the clinical setting under the direction of a knowledgeable leader.The function of the human brain will be considered with respect to learning experiences that contribute to effective medical physics knowledge structures. The characteristics of various types of educational activities will be compared with respect to their effectiveness for producing desired outcomes along with their limitations. Emphasis will be given to the design of highly-effective classroom/conference presentations, and activities will be demonstrated with an emphasis on using technology to enhance human performance of both learners and the learning facilitators. Learning Objectives: Develop and provide highly effective medical physics educational sessions. Use technology to enhance human performance in the educational process. Identify and analyze various models of educational activities Select and use educational activities that contribute value to the medical physics profession.« less

Effect of students' learning styles on classroom performance in problem-based learning.

PubMed

Alghasham, Abdullah A

2012-01-01

Since problem-based learning (PBL) sessions require a combination of active discussion, group interaction, and inductive and reflective thinking, students with different learning styles can be expected to perform differently in the PBL sessions. Using "Learning Style Inventory Questionnaire," students were divided into separate active and reflective learner groups. Tutors were asked to observe and assess the students' behavioral performance during the PBL sessions for a period of 5 weeks. A questionnaire of 24 items was developed to assess students' behavioral performance in PBL sessions. Active students tended to use multiple activities to obtain the needed information were more adjusted to the group norms and regulation and more skillful in using reasoning and problem-solving skills and in participation in discussion. On the other hand, reflective students used independent study more, listened actively and carefully to others and used previously acquired information in the discussion more frequently. Formative assessment quizzes did not indicate better performance of either group. There were no significant gender differences in PBL behavioral performance or quizzes' scores. Active and reflective learners differ in PBL class behavioral performance but not in the formative assessment. We recommend that students should be informed about their learning style and that they should learn strategies to compensate for any lacks in PBL sessions through self-study. Also, educational planners should ensure an adequate mix of students with different learning styles in the PBL groups to achieve PBL desired objectives.

To obtain information on how nursing students react to, think about and learn from digital recording as a learning and teaching method over time. Based on the teaching and learning philosophy of the university college, we used digital recording as a tool in our daily sessions in skills laboratory. However, most of the studies referred to in the background review had a duration of from only a few hours to a number of days. We found it valuable to design a study with a duration of two academic semesters. A descriptive and interpretative design was used. First-year bachelor-level students at the department of nursing participated in the study. Data collection was carried out by employing an 'online questionnaire'. The students answered five written, open-ended questions after each of three practical skill sessions. Kvale and Brinkmann's three levels of understanding were employed in the analysis. The students reported that digital recording affected factors such as feeling safe, secure and confident and that video recording was essential in learning and training practical skills. The use of cameras proved to be useful, as an expressive tool for peer learning because video recording enhances self-assessment, reflection, sensing, psychomotor performance and discovery learning. Digital recording enhances the student's awareness when acquiring new knowledge because it activates cognitive and emotional learning. The connection between tutoring, feedback and technology was clear. The digital recorder gives students direct and immediate feedback on their performance from the various practical procedures, and may aid in the transition from theory to practice. Students experienced more self-confidence and a feeling of safety in their performances. © 2016 John Wiley & Sons Ltd.

Metacognitive Training at Home: Does It Improve Older Adults' Learning?

Bailey, Heather; Dunlosky, John; Hertzog, Christopher

2010-01-01

Background Previous research has described the success of an intervention aimed at improving older adults' ability to regulate their learning. This metacognitive approach involves teaching older adults to allocate their study time more efficiently by testing themselves and restudying items that are less well learned. Objective Although this type of memory intervention has shown promise, training older adults to test themselves in the laboratory can be very time-intensive. Thus, the purpose of the present study is to transport the self-testing training method from the laboratory to home use. Methods A standard intervention design was used that included a pretraining session, multiple training sessions, and a posttraining session. Participants were randomly assigned to either the training group (n = 29) or the waiting list control group (n = 27). Moreover, we screened participants for whether they used the self-testing strategy during their pretraining test session. Results Compared to the performance of the control group, the training group displayed significant gains, which demonstrates that older adults can benefit from training themselves to use these skills at home. Moreover, the results of the present study indicate that this metacognitive approach can effectively improve older adults' learning, even in those who spontaneously self-test prior to training. Conclusions Training metacognitive skills, such as self-testing and efficient study allocation, can improve the ability to learn new information in healthy older adults. More importantly, older adult clients can be supplied with an at-home training manual, which will ease the burden on practitioners. PMID:20016124

The use of collaborative activities and simulation sessions in engineering education has been explored previously. However, few studies have investigated the relationship of these types of teaching innovations with other learner characteristics, such as self-efficacy and background knowledge. This study explored the effects of collaborative activities and simulation sessions on learning and the relationships between self-efficacy beliefs, background knowledge, and learning. Data were collected from two different terms in an upper division engineering course entitled Lean Manufacturing Systems Engineering. Findings indicated that the impact of collaborative activities and simulation sessions appears to be different, depending on the concepts being taught. Simulation sessions were found to have a significant effect on self-efficacy beliefs, and background knowledge had a mixed effect on learning. Overall the results of this study highlight the complex set of relationships between classroom innovations, learner characteristics, and learning.

The one-minute preceptor (OMP) is a time-efficient, learner-centered teaching method used in a busy ambulatory care setting. This project evaluated the effects of training experienced anatomy teachers in the use of the OMP in the gross anatomy laboratory on students' perceived learning. Second-year medical students from a five-year, undergraduate-entry, system- and problem-based medical program were divided randomly into two groups of 76 students each. The groups took part in the same gross anatomy laboratory session on different dates, supervised by the same two teachers (both with over 25 years of teaching experience). The teachers attended a workshop on the use of the OMP between the two sessions. Students were given a questionnaire at the end of the two sessions to indicate their agreements to statements regarding their learning experiences. Semistructured interviews were conducted with the two teachers after the second session. Results showed that training experienced anatomy teachers in the use of the OMP did not result in improvement of student learning perception in the gross anatomy laboratory. The experienced teachers have developed their own approaches with elements similar to those in the OMP: being learner centered and adaptable to individual student's needs, providing feedback, and enhancing teacher immediacy. They do not have an explicit structure such as the OMP, and are thus flexible and adaptive. Confining the teachers' teaching behaviors to the OMP structure could limit their performance. Although there are theoretical advantages for novice teachers in adopting the OMP technique, these advantages still need to be supported by further studies.

Purpose. To compare the learning of endovascular interventional skills by training on pig models versus virtual reality simulators. Methods. Twelve endovascular novices participated in a study consisting of a pig laboratory (P-Lab) and a virtual reality laboratory (VR-Lab). Subjects were stratified by experience and randomized into four training groups. Following 1 hr of didactic instruction, all attempted an iliac artery stenosis (IAS) revascularization in both laboratories. Onsite proctors evaluated performances using task-specific checklists and global rating scales, yielding a Total Score. Participants completed two training sessions of 3 hr each, using their group's assigned method (P-Lab x 2, P-Lab +more » VR-Lab, VR-Lab + P-Lab, or VR-Lab x 2) and were re-evaluated in both laboratories. A panel of two highly experienced interventional radiologists performed assessments from video recordings. ANCOVA analysis of Total Score against years of surgical, interventional radiology (IR) experience and cumulative number of P-Lab or VR-Lab sessions was conducted. Inter-rater reliability (IRR) was determined by comparing proctored scores with the video assessors in only the VR-Lab. Results. VR-Lab sessions improved the VR-Lab Total Score ({beta} 3.029, p = 0.0015) and P-Lab Total Score ({beta} = 1.814, p = 0.0452). P-Lab sessions increased the P-Lab Total Score ({beta} = 4.074, p < 0.0001) but had no effect on the VR-Lab Total Score. In the general statistical model, both P-Lab sessions ({beta} = 2.552, p = 0.0010) and VR-Lab sessions ({beta} 2.435, p = 0.0032) significantly improved Total Score. Neither previous surgical experience nor IR experience predicted Total Score. VR-Lab scores were consistently higher than the P-Lab scores ({delta} = 6.659, p < 0.0001). VR-Lab IRR was substantial (r = 0.649, p < 0.0008). Conclusions. Endovascular skills learned in the virtual environment may be transferable to the real catheterization laboratory as modeled in the P-Lab.« less

Medical education is moving toward active learning during large group lecture sessions. This study investigated the saturation and breadth of active learning techniques implemented in first year medical school large group sessions. Data collection involved retrospective curriculum review and semistructured interviews with 20 faculty. The authors piloted a taxonomy of active learning techniques and mapped learning techniques to attributes of learning-centered instruction. Faculty implemented 25 different active learning techniques over the course of 9 first year courses. Of 646 hours of large group instruction, 476 (74%) involved at least 1 active learning component. The frequency and variety of active learning components integrated throughout the year 1 curriculum reflect faculty familiarity with active learning methods and their support of an active learning culture. This project has sparked reflection on teaching practices and facilitated an evolution from teacher-centered to learning-centered instruction.

Background: Medical education is moving toward active learning during large group lecture sessions. This study investigated the saturation and breadth of active learning techniques implemented in first year medical school large group sessions. Methods: Data collection involved retrospective curriculum review and semistructured interviews with 20 faculty. The authors piloted a taxonomy of active learning techniques and mapped learning techniques to attributes of learning-centered instruction. Results: Faculty implemented 25 different active learning techniques over the course of 9 first year courses. Of 646 hours of large group instruction, 476 (74%) involved at least 1 active learning component. Conclusions: The frequency and variety of active learning components integrated throughout the year 1 curriculum reflect faculty familiarity with active learning methods and their support of an active learning culture. This project has sparked reflection on teaching practices and facilitated an evolution from teacher-centered to learning-centered instruction. PMID:29707649

Background The current literature on undergraduate interprofessional education (IPE) for pharmacy and medical students highlights a range of positive outcomes, although to date IPE has focused predominantly on student views and experiences of IPE sessions with these opinions being sought at the end of the sessions. This study aimed to evaluate medical students’ experiences of therapeutics and prescribing IPE, with pharmacy students, 1 year following the session. Methods Following ethics committee approval, 3rd year medical students at Cardiff University were invited to participate using non-probability sampling. Topic guide development was informed by the literature and research team discussions, including a review of the materials used in the IPE session. Semi-structured one-to-one interviews explored experiences, prior to, during, and after the IPE session. Interviews were audio-recorded, transcribed verbatim, and analyzed thematically. Results Eighteen medical students were interviewed; 11 were females. Seven themes were identified, namely 1) refinement of pre-session preparation, 2) session value, 3) learning with a pharmacy student, 4) learning about a pharmacist, 5) learning from a pharmacy student, 6) importance and application of what was learnt into practice, and 7) suggestions for change. Conclusion This study provides a valuable insight into medical students’ experiences of a therapeutics and prescribing IPE session and emphasizes the value they placed on interaction with pharmacy students. Medical students were able to recall clear learning experiences from the IPE session that had taken place 12 months earlier, which itself is an indicator of the impact of the session on the students. Furthermore, they were able to describe how knowledge and skills learnt had been applied to subsequent learning activities. Those developing IPE sessions should consider the following: clarify professional roles in the session content, incorporate IPE as a series of activities, and use small groups of students to optimize student–student interaction and active learning.

A blended approach encompassing problem-based learning (PBL) and structured inquiry was used in this laboratory exercise based on the congenital disease Osteogenesis imperfecta (OI), to introduce commonly used techniques in biomolecular analysis within a clinical context. During a series of PBL sessions students were presented with several scenarios involving a 2 year old child, who had experienced numerous fractures. Key learning goals related to both the theory and practical aspects of the course, covering biomolecular analysis and functional genomics, were identified in successive PBL sessions. The laboratory exercises were conducted in 3 hour blocks over six weeks, focused firstly on protein analysis, followed by nucleic acids. Students isolated collagen from normal and OI affected fibroblast cultures. Analysis by SDS-PAGE demonstrated α1 and α2 of collagen Type I chains at approximately 95 kDa and 92 kDa, respectively. Subtle differences in protein mobility between the control and OI samples were observed by some students, but most considered it inconclusive as a diagnostic tool. The nucleic acid module involved isolation of RNA from OI affected fibroblasts. The RNA was reverse transcribed and used as template to amplify a 354 bp COL1A1 fragment. Students were provided with the sequence of the OI affected COL1A1 PCR product aligned with the normal COL1A1 sequence, allowing identification of the mutation, as the substitution of Arg for Gly(976) of the triple helical region. Our experience with student cohorts over several years is that presentation of this laboratory exercise within a relevant clinical context, and the opportunity for active engagement with the experimental procedures via PBL sessions, supported the learning of basic theory and practical techniques of biomolecular analysis.

Background music has been reported to enhance learning in the cadaver dissection laboratory. This study was designed to determine the impact of various forms of musical genre and some of their characteristics on students' learning outcome in the dissection laboratory. Some selected musical genre in vocal and non-vocal forms and at different tempi and volume were played as background music (BM) to 253 Medical and Dental students during various sessions of cadaver dissection. Psychological Stress assessment was done using Psychological stress measure-9. Participants love for music, preferred musical genre and other musical characteristics were assessed. The impact of the various musical genre and their characteristics on learning was done via written examination on the region dissected during each musical session. A positive relationship was noted between students' preference for musical genre during leisure with their preference for BM during private study time (P<0.01). Statistically significant differences (P<0.01) were established in the impacts of the selected musical genre on some selected learning factors. Country and Classical music gave the highest positive impact on the various learning factors in CDL followed by R&B. No significant difference was noted between the cognitive values of vocal and non-vocal music. Classical music most effectively reduced the stress induced by dissection in the CDL while Reggae and High life musical genre created a more stressful environment than regular background noise (P<0.01). Moderate volume level and Tempo were most preferred during both cadaver dissection activity and leisure hours. This study shows statistically significant differences in the cognitive values of some of the studied musical genre and their various characteristics. The inability to isolate the particular musical genre with these desired properties could account for the controversies in the reports of the role of music in academic environment.

Caffeine effects on mood and memory.

PubMed

Herz, R S

1999-09-01

The purpose of the present research was to assess whether a psychoactive dose of caffeine would have differential affects on the mood dimensions of arousal versus feelings of pleasantness and whether these mood alterations would influence memory either by (1) the experience of arousal at learning and/or (2) altered and congruent mood states at learning and recall. To address these questions, the administration of 5 mg/kg caffeine or placebo at learning and retrieval sessions was manipulated and subjects' mood was evaluated by several different self-report measures. Sixteen words were incidentally studied during the learning session and memory was evaluated by the number of words correctly recalled at the retrieval session two days later. Results revealed that caffeine reliably increased arousal, but did not affect any emotion dimensions related to feelings of pleasure. Subjects who received caffeine at learning and retrieval were also in equivalent mood states at both sessions. Moreover, caffeine did not produce any effects on memory; thus, neither hypothesis concerning the influence of arousal on memory was supported. These data show that caffeine is a useful method for manipulating arousal in the laboratory without influencing feelings of pleasantness or learning and memory performance.

Practical sessions in undergraduate medical education are often costly and have to face constraints in terms of available laboratory time and practice materials (e.g. blood samples from animals). This makes it difficult to increase the time each student spends at the laboratory. We consider that it would be possible to improve the effectiveness of the laboratory time by providing the students with computer-based simulations for prior rehearsal. However, this approach still presents issues in terms of development costs and distribution to the students. This study investigates the employment of low-cost simulation to allow medical students to rehearse practical exercises through a web-based e-learning environment. The aim is to maximize the efficiency of laboratory time and resources allocated by letting students become familiarized with the equipment and the procedures before they attend a laboratory session, but without requiring large-scale investment. Moreover, students can access the simulation via the Internet and rehearse at their own pace. We have studied the effects of such a simulation in terms of impact on the laboratory session, learning outcomes and student satisfaction. We created a simulation that covers the steps of a practical exercise in a Physiology course (measuring hematocrit in a blood sample). An experimental group (EG, n=66) played the simulation 1 week before the laboratory session. A control group (CG, n=77) attended the laboratory session without playing the simulation. After the session, all students completed a survey about their perception of the difficulty of the exercise on a scale of 1-10 and the HCT final value that they obtained. The students in the EG also completed a survey about their satisfaction with the experience. After the laboratory session, the perceived difficulty of the procedure was lower on average in the EG compared to the CG (3.52 vs. 4.39, 95% CI: 0.16-1.57, P=.016). There was no significant difference in terms of perceived difficulty using the equipment. The HCT measures reported by the EG group also presented a much lower dispersion, meaning a higher reliability, in determining the HCT value (3.10 vs. 26.94, SD; variances significantly different, P<.001, F: 75.25, Dfd: 68.19 for EG and CG). In the satisfaction test, the majority of the students in the EG reported that the experience was positive or very positive (80.7%) and reported that it had helped them to identify and use the equipment (78%) and to perform the exercise (66%). The simulation was well received by students in the EG, who felt more comfortable during the laboratory session, and it helped them to perform the exercise better, obtaining more accurate results, which indicates more effective training. EG students perceived the procedure as easier to perform, but did not report an improvement in the perceived difficulty in using the equipment. The increased reliability demonstrates that low-cost simulations are a good complement to the laboratory sessions. Copyright 2010 Elsevier Ireland Ltd. All rights reserved.

Stress is widely known to alter behavioral responses to rewards and punishments. It is believed that stress may precipitate these changes through modulation of corticostriatal circuitry involved in reinforcement learning and motivation, although the intervening mechanisms remain unclear. One candidate is inflammation, which can rapidly increase following stress and can disrupt dopamine-dependent reward pathways. Here, in a sample of 88 healthy female participants, we first assessed the effect of an acute laboratory stress paradigm on levels of plasma interleukin-6 (IL-6), a cytokine known to be both responsive to stress and elevated in depression. In a second laboratory session, we examined the effects of a second laboratory stress paradigm on reward prediction error (RPE) signaling in the ventral striatum. We show that individual differences in stress-induced increases in IL-6 (session 1) were associated with decreased ventral striatal RPE signaling during reinforcement learning (session 2), though there was no main effect of stress on RPE. Furthermore, changes in IL-6 following stress predicted intraindividual variability in perceived stress during a 4-month follow-up period. Taken together, these data identify a novel link between IL-6 and striatal RPEs during reinforcement learning in the context of acute psychological stress, as well as future appraisal of stressful life events.

2007-01-01

Longitudinal changes in brain activity during second language (L2) acquisition of a miniature finite-state grammar, named Wernickese, were identified with functional magnetic resonance imaging (fMRI). Participants learned either a visual sign language form or an auditory-verbal form to equivalent proficiency levels. Brain activity during sentence comprehension while hearing/viewing stimuli was assessed at low, medium, and high levels of proficiency in three separate fMRI sessions. Activation in the left inferior frontal gyrus (Broca’s area) correlated positively with improving L2 proficiency, whereas activity in the right-hemisphere (RH) homologue was negatively correlated for both auditory and visual forms of the language. Activity in sequence learning areas including the premotor cortex and putamen also correlated with L2 proficiency. Modality-specific differences in the blood oxygenation level-dependent signal accompanying L2 acquisition were localized to the planum temporale (PT). Participants learning the auditory form exhibited decreasing reliance on bilateral PT sites across sessions. In the visual form, bilateral PT sites increased in activity between Session 1 and Session 2, then decreased in left PT activity from Session 2 to Session 3. Comparison of L2 laterality (as compared to L1 laterality) in auditory and visual groups failed to demonstrate greater RH lateralization for the visual versus auditory L2. These data establish a common role for Broca’s area in language acquisition irrespective of the perceptual form of the language and suggest that L2s are processed similar to first languages even when learned after the ‘‘critical period.’’ The right frontal cortex was not preferentially recruited by visual language after accounting for phonetic/structural complexity and performance.

A Novel Teaching Tool Combined With Active-Learning to Teach Antimicrobial Spectrum Activity.

PubMed

MacDougall, Conan

2017-03-25

Objective. To design instructional methods that would promote long-term retention of knowledge of antimicrobial pharmacology, particularly the spectrum of activity for antimicrobial agents, in pharmacy students. Design. An active-learning approach was used to teach selected sessions in a required antimicrobial pharmacology course. Students were expected to review key concepts from the course reader prior to the in-class sessions. During class, brief concept reviews were followed by active-learning exercises, including a novel schematic method for learning antimicrobial spectrum of activity ("flower diagrams"). Assessment. At the beginning of the next quarter (approximately 10 weeks after the in-class sessions), 360 students (three yearly cohorts) completed a low-stakes multiple-choice examination on the concepts in antimicrobial spectrum of activity. When data for students was pooled across years, the mean number of correct items was 75.3% for the items that tested content delivered with the active-learning method vs 70.4% for items that tested content delivered via traditional lecture (mean difference 4.9%). Instructor ratings on student evaluations of the active-learning approach were high (mean scores 4.5-4.8 on a 5-point scale) and student comments were positive about the active-learning approach and flower diagrams. Conclusion. An active-learning approach led to modestly higher scores in a test of long-term retention of pharmacology knowledge and was well-received by students.

In this study, we examined the regularly scheduled, formal teaching sessions in a single anesthesiology residency program to (1) map the most common primary instructional methods, (2) map the use of 10 known teaching techniques, and (3) assess if residents scored sessions that incorporated active learning as higher quality than sessions with little or no verbal interaction between teacher and learner. A modified Delphi process was used to identify useful teaching techniques. A representative sample of each of the formal teaching session types was mapped, and residents anonymously completed a 5-question written survey rating the session. The most common primary instructional methods were computer slides-based classroom lectures (66%), workshops (15%), simulations (5%), and journal club (5%). The number of teaching techniques used per formal teaching session averaged 5.31 (SD, 1.92; median, 5; range, 0-9). Clinical applicability (85%) and attention grabbers (85%) were the 2 most common teaching techniques. Thirty-eight percent of the sessions defined learning objectives, and one-third of sessions engaged in active learning. The overall survey response rate equaled 42%, and passive sessions had a mean score of 8.44 (range, 5-10; median, 9; SD, 1.2) compared with a mean score of 8.63 (range, 5-10; median, 9; SD, 1.1) for active sessions (P = 0.63). Slides-based classroom lectures were the most common instructional method, and faculty used an average of 5 known teaching techniques per formal teaching session. The overall education scores of the sessions as rated by the residents were high.

Aims and method To develop and evaluate a novel teaching session on clinical assessment using role play simulation. Teaching and research sessions occurred sequentially in computer laboratories. Ten medical students were divided into two online small-group teaching sessions. Students role-played as clinician avatars and the teacher played a suicidal adolescent avatar. Questionnaire and focus-group methodology evaluated participants’ attitudes to the learning experience. Quantitative data were analysed using SPSS, qualitative data through nominal-group and thematic analyses. Results Participants reported improvements in psychiatric skills/knowledge, expressing less anxiety and more enjoyment than role-playing face to face. Data demonstrated a positive relationship between simulator fidelity and perceived utility. Some participants expressed concern about added value over other learning methods and non-verbal communication. Clinical implications The study shows that virtual worlds can successfully host role play simulation, valued by students as a useful learning method. The potential for distance learning would allow delivery irrespective of geographical distance and boundaries. PMID:25285217

Engaging Non-Science Majors Through Citizen Science Projects In Inquiry-Based Introductory Geoscience Laboratory Courses

2010-12-01

Although inquiry-based/problem-based methods have been successfully incorporated in undergraduate lecture classes, a survey of commonly used laboratory manuals indicates that few non-major geoscience laboratory classes use these strategies. The Department of Geology and Environmental Geosciences faculty members have developed a successful introductory Environmental Geology Laboratory course for undergraduate non-majors that challenges traditional teaching methodology as illustrated in most laboratory manuals. The Environmental Geology lab activities employ active learning methods to engage and challenge students. Crucial to establishing an open learning environment is capturing the attention of non-science majors from the moment they enter the classroom. We use catastrophic ‘gloom and doom’ current events to pique the imagination with images, news stories, and videos. Once our students are hooked, we can further the learning process with use of other teaching methods: an inquiry-based approach that requires students take control of their own learning, a cooperative learning approach that requires the participation of all team members in peer learning, and a problem/case study learning approach that primarily relies on activities distilled from current events. The final outcome is focused on creating innovative methods to communicate the findings to the general public. With the general public being the audience for their communiqué, students are less intimated, more focused, and more involved in solving the problem. During lab sessions, teams of students actively engage in mastering course content and develop essential communication skills while exploring real-world scenarios. These activities allow students to use scientific reasoning and concepts to develop solutions for scenarios such as volcanic eruptions, coastal erosion/sea level rise, flooding or landslide hazards, and then creatively communicate their solutions to the public. For example, during a two-week section on Earthquakes, teams study the effects of seismic motion on sediments underlying the Charleston, South Carolina region. Students discover areas where the greatest damage occurred during the 1886 earthquake via a walking tour of Charleston. Extracting information from historical and topographic maps, and aerial and satellite imagery provides students with the necessary information to produce an earthquake hazard map of the area. Applying the creativity and knowledge base of the multidisciplinary students generates a startling array of innovative methods for communicating their results: brochures, storybooks, computer-animated hazard maps, Facebook pages, YouTube videos - even Virtual Reality avatars! When allowed to use their imaginations and resourcefulness, these students have no bounds! Not only does the application of inquiry-based problem solving methodology in conjunction with cooperative learning enhance comprehension of the material, but by allowing undergraduate students to develop methods of communicating their knowledge to the public through an interesting variety of medium, students remain focused, engaged, and even excited about learning science that otherwise intimidated them.

We are what we do: Examining learner-generated content in the anatomy laboratory through the lens of activity theory.

Doubleday, Alison F; Wille, Sarah J

2014-01-01

Video and photography are often used for delivering content within the anatomical sciences. However, instructors typically produce these resources to provide instructional or procedural information. Although the benefits of learner-generated content have been explored within educational research, virtually no studies have investigated the use of learner-generated video and photograph content within anatomy dissection laboratories. This study outlines an activity involving learner-generated video diaries and learner-generated photograph assignments produced during anatomy laboratory sessions. The learner-generated photographs and videos provided instructors with a means of formative assessment and allowed instructors to identify evidence of collaborative behavior in the laboratory. Student questionnaires (n = 21) and interviews (n = 5), as well as in-class observations, were conducted to examine student perspectives on the laboratory activities. The quantitative and qualitative data were examined using the framework of activity theory to identify contradictions between student expectations of, and engagement with, the activity and the actual experiences of the students. Results indicate that learner-generated photograph and video content can act as a rich source of data on student learning processes and can be used for formative assessment, for observing collaborative behavior, and as a starting point for class discussions. This study stresses the idea that technology choice for activities must align with instructional goals. This research also highlights the utility of activity theory as a framework for assessing classroom and laboratory activities, demonstrating that this approach can guide the development of laboratory activities. © 2014 American Association of Anatomists.

Objective. To design and implement a series of activities focused on developing interprofessional communication skills and to assess the impact of the activities on students’ attitudes and achievement of educational goals. Design. Prior to the first pharmacy practice skills laboratory session, pharmacy students listened to a classroom lecture about team communication and viewed short videos describing the roles, responsibilities, and usual work environments of four types of health care professionals. In each of four subsequent laboratory sessions, students interacted with a different standardized health care professional role-played by a pharmacy faculty member who asked them a medication-related question. Students responded in verbal and written formats. Assessment. Student performance was assessed with a three-part rubric. The impact of the exercise was assessed by conducting pre- and post-intervention surveys and analyzing students’ performance on relevant Center for the Advancement of Pharmacy Education (CAPE) outcomes. Survey results showed improvement in student attitudes related to team-delivered care. Students’ performance on the problem solver and collaborator CAPE outcomes improved, while performance on the educator outcome worsened. Conclusions. The addition of an interprofessional communication activity with standardized health care professionals provided the opportunity for students to develop skills related to team communication. Students felt the activity was valuable and realistic; however, analysis of outcome achievement from the exercise revealed a need for more exposure to team communication skills. PMID:28289305

2003-12-01

Moclobemide is a well known drug with antidepressant action. The aim of this study was to investigate the effects of moclobemide on learning and memory processes in Sprague Dawley rats. Over a 5-day period, learning sessions with 30 trials per day and memory retention tests were performed. The conditioned responses (avoidances), the unconditioned responses (escapes) and the intertrial crossings were observed. An active avoidance test was carried out using a shuttle box. Two passive avoidance tests were used: step-through (using a light chamber) and step-down (using a platform). In the step-through passive avoidance test, the learning and retention sessions consisted of three trials each and the latency of reaction times (the rat remaining in the light chamber for more than 180 sec) was used as criterion. In the step-down passive avoidance test, learning and retention sessions consisted of two trials and the latency of reaction times (the rat remaining on the platform for 60 sec) was used as criterion. In the active avoidance tests, moclobemide dose-dependently increased the number of avoidances during learning sessions and maintained this number in memory retention tests. Moclobemide did not alter the number of escapes, but did increase motor activity. In the passive avoidance tests, moclobemide also increased the latency of reaction times in learning and short memory retrieval tests. These findings suggest that moclobemide improves learning and memory processes in active and passive avoidance tests and has a cognition-enhancing effect. (c) 2003 Prous Science

Core content in Emergency Medicine Residency Programs is traditionally covered in didactic sessions, despite evidence suggesting that learners do not retain a significant portion of what is taught during lectures. We describe techniques that medical educators can use when leading teaching sessions to foster engagement and encourage self-directed learning, based on current literature and evidence about learning. When these techniques are incorporated, sessions can be effective in delivering core knowledge, contextualizing content, and explaining difficult concepts, leading to increased learning.

Active research-driven approaches that successfully incorporate new technology are known to catalyze student learning. Yet achieving these objectives in neuroscience education is especially challenging due to the prohibitive costs and technical demands of research-grade equipment. Here we describe a method that circumvents these factors by leveraging consumer EEG-based neurogaming technology to create an affordable, scalable, and highly portable teaching laboratory for undergraduate courses in neuroscience. This laboratory is designed to give students hands-on research experience, consolidate their understanding of key neuroscience concepts, and provide a unique real-time window into the working brain. Survey results demonstrate that students found the lab sessions engaging. Students also reported the labs enhanced their knowledge about EEG, their course material, and neuroscience research in general. PMID:28690430

Methods of learning in statistical education: Design and analysis of a randomized trial

NASA Astrophysics Data System (ADS)

Boyd, Felicity Turner

Background. Recent psychological and technological advances suggest that active learning may enhance understanding and retention of statistical principles. A randomized trial was designed to evaluate the addition of innovative instructional methods within didactic biostatistics courses for public health professionals. Aims. The primary objectives were to evaluate and compare the addition of two active learning methods (cooperative and internet) on students' performance; assess their impact on performance after adjusting for differences in students' learning style; and examine the influence of learning style on trial participation. Methods. Consenting students enrolled in a graduate introductory biostatistics course were randomized to cooperative learning, internet learning, or control after completing a pretest survey. The cooperative learning group participated in eight small group active learning sessions on key statistical concepts, while the internet learning group accessed interactive mini-applications on the same concepts. Controls received no intervention. Students completed evaluations after each session and a post-test survey. Study outcome was performance quantified by examination scores. Intervention effects were analyzed by generalized linear models using intent-to-treat analysis and marginal structural models accounting for reported participation. Results. Of 376 enrolled students, 265 (70%) consented to randomization; 69, 100, and 96 students were randomized to the cooperative, internet, and control groups, respectively. Intent-to-treat analysis showed no differences between study groups; however, 51% of students in the intervention groups had dropped out after the second session. After accounting for reported participation, expected examination scores were 2.6 points higher (of 100 points) after completing one cooperative learning session (95% CI: 0.3, 4.9) and 2.4 points higher after one internet learning session (95% CI: 0.0, 4.7), versus nonparticipants or controls, adjusting for other performance predictors. Students who preferred learning by reflective observation and active experimentation experienced improved performance through internet learning (5.9 points, 95% CI: 1.2, 10.6) and cooperative learning (2.9 points, 95% CI: 0.6, 5.2), respectively. Learning style did not influence study participation. Conclusions. No performance differences by group were observed by intent-to-treat analysis. Participation in active learning appears to improve student performance in an introductory biostatistics course and provides opportunities for enhancing understanding beyond that attained in traditional didactic classrooms.

Are treatment effects of neurofeedback training in children with ADHD related to the successful regulation of brain activity? A review on the learning of regulation of brain activity and a contribution to the discussion on specificity

While issues of efficacy and specificity are crucial for the future of neurofeedback training, there may be alternative designs and control analyses to circumvent the methodological and ethical problems associated with double-blind placebo studies. Surprisingly, most NF studies do not report the most immediate result of their NF training, i.e., whether or not children with ADHD gain control over their brain activity during the training sessions. For the investigation of specificity, however, it seems essential to analyze the learning and adaptation processes that take place in the course of the training and to relate improvements in self-regulated brain activity across training sessions to behavioral, neuropsychological and electrophysiological outcomes. To this aim, a review of studies on neurofeedback training with ADHD patients which include the analysis of learning across training sessions or relate training performance to outcome is presented. Methods on how to evaluate and quantify learning of EEG regulation over time are discussed. “Non-learning” has been reported in a small number of ADHD-studies, but has not been a focus of general methodological discussion so far. For this reason, selected results from the brain-computer interface (BCI) research on the so-called “brain-computer illiteracy”, the inability to gain control over one’s brain activity, are also included. It is concluded that in the discussion on specificity, more attention should be devoted to the analysis of EEG regulation performance in the course of the training and its impact on clinical outcome. It is necessary to improve the knowledge on characteristic cross-session and within-session learning trajectories in ADHD and to provide the best conditions for learning. PMID:25870550

Issues related to traditional Problem-Based Learning (PBL) at King Abdulaziz University Faculty of Medicine (KAU-FOM), including lack of student interaction between sessions and outdated instructional materials have led to the examining the use of social media. This study examines factors affecting the implementation of social media into PBL sessions Methods: Mentored social media activities were incorporated between PBL sessions to third year medical students. Ground rules were set, and students were kept on track with learning objectives and authentic references. An online survey consisting of 18 questions were administered to measure the impact of the social media model embedded between PBL sessions. Feedback showed major improvements in students' learning process as well as identifying areas for improvement. The highest ratings were in participation and communication, knowledge and information gathering, and cooperation and team-building. This paper indicates that incorporating social media could facilitate learning between PBL sessions. Furthermore, guidelines are proposed to help educators implement a social media model into their PBL sessions.

Recent advances in exoskeleton technology has made lower extremity powered exoskeletons (LEPE) a viable treatment tool to restore upright walking mobility to persons with spinal cord injury (SCI). Evaluate ARKE exoskeleton training within a rehabilitation centre environment. Case studies are presented for two male participants, age 41 and 30, motor complete SCI at T6 (N01) and T12 (N02), respectively, as they progress from new LEPE users to independent walking. The ARKE 2.0 LEPE (Bionik Laboratories Inc., Toronto, Canada) was used for all training (hip and knee powered, forearm crutches, control tablet). Data were collected on session times, activity metrics from ARKE system logs, and qualitative questionnaire feedback. N01 required 18, 30-minute training sessions to achieve independent walking. N01 walked independently within the 12 session target. Foot strikes were frequently before the end of the programmed swing phase, which were handled by the ARKE control system. Subjective ratings of LEPE learning, comfort, pain, fatigue, and overall experience were high for sitting-standing and moderate to high for walking. This reflected the complexity of learning to safely walk. Qualitative feedback supported the continuation of LEPE use in rehabilitation settings based on end-user desire for upright mobility.

The purpose of the present trial was to develop and evaluate an educational program for promotion of healthy nutrition and physical activity by health volunteers. The educational program consisted of the following four phases: preliminary self-learning by mail (3 weeks), basic learning (3 sessions of 3 hours), practice of planned activities (2 months), and a report session (1 session of 3 hours). Beginner volunteers (n=18, mean age 63.3 +/- 6.4) were recruited from two volunteer health organizations in Kurume city. They then participated in a program that taught basic health knowledge regarding nutrition and physical activity, how to plan effective support activities, and methods for self-evaluation. In the preliminary self-learning phase, an assessment sheet, health information, and homework (goal setting, etc.) were delivered to the volunteers by mail. In the basic learning phase, volunteers attended a 3 day seminar on essential principles for behavioral change and assessment methods for volunteer activity. In addition, effective support activities were planned through group discussion. After a 2-month practice of support activities, each group reported and discussed the results of their activity in a 3-hour report session. Main outcome measures were health knowledge (15 items, 0-1 points), self-efficacy for life style support (5 items, 0-100%), and evaluation of the educational program (9 items, 1-5 points). All measures were self-administered. Significant increases in rate of true answers for health knowledge were observed during the preliminary self-learning and before basic learning phases (54.8% --> 67.1%, P < 0.05), and before and after basic learning phases (67.1% --> 87.6%, P < 0.05). Self-efficacy for life style support were significantly higher after the report session than before the preliminary self-learning phase (35.1% --> 53.1%, P < 0.05). In the two-month practice, all groups received feedback through questionnaires completed by participants who took part in their planned activity. The mean scores for the overall evaluation of the program, the effectiveness of the course materials and group-work, the staff, and the course contents were all higher than 4.0 points. These findings indicate that this program is structured effectively and is appropriate for educating beginner health volunteers regarding promotion of healthy nutrition and physical activity.

Student-centred learning (SCL) places the student at the centre of policies, practices and decision-making in the teaching-learning process. SCL methodology also advocates active involvement of students in the curriculum planning, selection of teaching-learning methods and assessment process. We planned an education innovation project to assess the perception of fifth semester undergraduate medical students towards implementation of an SCL methodology. The study was done among 87 fifth semester undergraduate medical students (batch of 2010-11) in the noncommunicable disease epidemiology section of Community Medicine at the Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER), Puducherry. The students divided themselves into seven groups and developed the learning objectives, selected teaching-learning methods and assessment process for each session. The facilitators had 3-5 rounds of interaction with each group before the session. Qualitative analysis of feedback collected from students and external faculty after each session was done. The effect of implementing the SCL methodology was assessed by the reaction level of Kirkpatrick's training evaluation model by using a rating scale Results. Of the 87 eligible students, 73 (83.9%) returned the forms for evaluation. All seven groups were able to formulate the learning objectives. Most of the groups had used PowerPoint slides and videos as a teaching-learning tool. Innovative assessment methods such as crosswords and 'chocopati' were used by some groups. In general, the perception of students was favourable towards SCL compared to conventional methods and they felt that this methodology should be adopted more often. Time management and organization of sessions were the main problems encountered by the students. The mean (SD) score for the items 'sessions were useful', 'sessions were enjoyable' and 'sessions improved my knowledge' were 6.2 (1.8), 7.1 (1.8) and 6.3 (1.9), respectively. The majority of students found the sessions on innovative teaching-learning and assessment techniques enjoyable, useful and informative. The sessions showed that students took an active part in curriculum planning, execution and evaluation. Copyright 2014, NMJI.

Successful practice of clinical pathology depends on a wide variety of laboratory, clinical, and managerial decisions. The skills needed to make these decisions can most effectively be learned by residents and fellows in pathology using a service-oriented on-call approach. We report our experience implementing an on-call system in the clinical chemistry laboratory at the University of Louisville Hospital (Ky). We detail the guidelines used to establish this system and the elements required for its successful implementation. The system emphasizes a laboratory-initiated approach to linking laboratory results to patient care. From inception of the program during late 1990 through 1995, the number of beeper calls (including clinician contacts) steadily increased and is currently 8 to 20 per week. The on-call system is active 24 hours per day, 7 days per week, thus representing activity on all three laboratory shifts. Types of responses were separated into administrative (12%), analytical (42%), clinical (63%), quality control or quality assurance (12%), and consultation (13%) categories. We also present 6 case reports as examples demonstrating multiple elements in these categories. In 23% of the calls, clinician contact was required and achieved by the fellow or resident on call for the laboratory. The on-call reports are documented and presented informally at weekly on-call report sessions. Emphasis is placed on learning and refinement of investigative skills needed to function as an effective laboratory director. Educational emphasis for the medical staff is in establishing awareness of the presence of the laboratory as an important interactive component of patient care. In addition, we found this program to be beneficial to the hospital and to the department of pathology in fulfilling its clinical service and teaching missions. Our experience may be helpful to other institutions establishing such a program.

Background: At present, in a medical school, students are taught in different departments, subject-wise, without integration to interrelate or unify subjects and these results in compartmentalization of medical education, with no stress on case-based learning. Therefore, an effort was made to develop and adopt integrated teaching in order to have a better contextual knowledge among students. Methodology and Implementation: After the faculty orientation training, four “topic committees” with faculty members from different departments were constituted which decided and agreed on the content material to be taught, different methodologies to be used, along with the logical sequencing of the same for the purpose of implementation. Different teaching methodologies used, during the program, were didactic lectures, case stimulated sessions, clinical visits, laboratory work, and small group student's seminar. Results: After the implementation of program, the comparison between two batches as well as between topics taught with integrated learning program versus traditional method showed that students performed better in the topics, taught with integrated approach. Students rated “clinical visits” as very good methodology, followed by “case stimulated interactive sessions.” Students believed that they felt more actively involved, and their queries are better addressed with such interactive sessions. Conclusion: There is a very good perception of students toward integrated teaching. Students performed better if they are taught using this technique. Although majority of faculty found integrated teaching, as useful method of teaching, nevertheless extra work burden and interdepartmental coordination remained a challenging task. PMID:26380204

Challenging the Non-Science Majors with Inquiry-based Laboratory Environmental Geoscience Courses

Humphreys, R. R.; Hall, C.; Colgan, M. W.

2009-12-01

Although there is proven rationale for teaching inquiry-based/problem-based lessons in the undergraduate classroom, very few non-major geoscience course implement these instructional strategies in their laboratory sections. The College of Charleston Department of Geology and Environmental Geosciences has developed an introductory Environmental Geology Laboratory course for undergraduate non-majors, which corrects this traditional methodology. The Environmental Geology lab activities employ an inquiry-based approach, in which the students take control of their own learning; a cooperative learning approach, in which each member of a team is responsible not only for learning what is taught but also for helping their peers learn; and a problem/case study-based learning approach, in which activities are abstracted from a real-life scenario. In these lab sessions, students actively engage in mastering course content and develop essential skills while exploring real-world scenarios through case studies. For example, during the two-week section on Earthquakes, teams of students study the effects of seismic motion on various types of sediments found underlying the Charleston, South Carolina region. Students discover areas where the greatest damage occurred during the 1886 7.4 MM earthquake through a walking tour of downtown Charleston. Extracting information from historical and topographic maps, as well as aerial and satellite imagery provides students with the necessary information to produce an earthquake hazard-zone map of the Charleston Peninsula. These types of exercises and laboratory activities allow the students to utilize scientific reasoning and application of scientific concepts to develop solutions to environmental scenarios, such as volcanic eruptions, coastal, flooding, or landslide hazards, and groundwater contamination. The newly implemented labs began in Fall of 2008 and have been undergoing adaptations throughout the Spring and Fall of 2009. Qualitative data will be gathered and analyzed to show the effectiveness of moving beyond traditional laboratory teaching methods to methods that require and promote deeper learning and retaining of content. Qualitative data will be based upon the engagement of the students, the deeper level of questioning, the engagement of the faculty, among others. The data will be acquired through the use of personal responses and end of course surveys. For the Spring 2009 semester, the department will develop a more quantitative means of assessment by integrating a pre- and post-survey for this course as well as the traditionally-taught introductory course. Acquisition of knowledge and depth of knowledge by the students from both types of courses will be obtained and compared for assessing effectiveness of this teaching strategy in a laboratory setting. This data will encourage the faculty teaching Environmental Geology Labs as well as the standard introductory labs to redesign the remaining lab courses. In addition, the method used here may serve as a model for laboratory courses in other disciplines.

Activity-Based Introductory Physics Reform *

Physics education research has shown that learning environments that engage students and allow them to take an active part in their learning can lead to large conceptual gains compared to those of good traditional instruction. Examples of successful curricula and methods include Peer Instruction, Just in Time Teaching, RealTime Physics, Workshop Physics, Scale-Up, and Interactive Lecture Demonstrations (ILDs). RealTime Physics promotes interaction among students in a laboratory setting and makes use of powerful real-time data logging tools to teach concepts as well as quantitative relationships. An active learning environment is often difficult to achieve in large lecture sessions and Workshop Physics and Scale-Up largely eliminate lectures in favor of collaborative student activities. Peer Instruction, Just in Time Teaching, and Interactive Lecture Demonstrations (ILDs) make lectures more interactive in complementary ways. This presentation will introduce these reforms and use Interactive Lecture Demonstrations (ILDs) with the audience to illustrate the types of curricula and tools used in the curricula above. ILDs make use real experiments, real-time data logging tools and student interaction to create an active learning environment in large lecture classes. A short video of students involved in interactive lecture demonstrations will be shown. The results of research studies at various institutions to measure the effectiveness of these methods will be presented.

This study examined the very initial phases of orthographic and semantic acquisition in monolingual native English speakers learning Chinese words under controlled laboratory conditions. Participants engaged in 10 sessions of vocabulary learning, four of which were used to obtain ERPs. Performance in behavioral tests improved over sessions, and these data were used to define fast and slow learners. Most important is that ERPs in the two groups of learners revealed qualitatively distinct learning patterns. Only fast learners showed a left-lateralized increase in N170 amplitude with training. Furthermore, only fast learners showed an increased N400 amplitude with training, with a distinct anterior distribution. Slow learners, on the other hand, showed a posterior positive effect, with increasingly positive-going waveforms in occipital sites as training progressed. Possible mechanisms underlying these qualitative differences are discussed. Copyright © 2014 Society for Psychophysiological Research.

Theoretical knowledge in biology and medicine plays a substantial role in laboratory medicine resident education. In this study, we assessed the contribution of problem-based learning (PBL) to improve the training of laboratory medicine residents during their internship in the department of virology, Strasbourg University Hospital, France. We compared the residents' satisfaction regarding an educational program based on PBL and a program based on lectures and presentations. PBL induced a high level of satisfaction (100%) among residents compared to lectures and presentations (53%). The main advantages of this technique were to create a situational interest regarding virological problems, to boost the residents' motivation and to help them identify the most relevant learning objectives in virology. However, it appears pertinent to educate the residents in appropriate bibliographic research techniques prior to PBL use and to monitor their learning by regular formative assessment sessions.

Memory consolidation within the central amygdala is not necessary for modulation of cerebellar learning.

PubMed

Steinmetz, Adam B; Ng, Ka H; Freeman, John H

2017-06-01

Amygdala lesions impair, but do not prevent, acquisition of cerebellum-dependent eyeblink conditioning suggesting that the amygdala modulates cerebellar learning. Two-factor theories of eyeblink conditioning posit that a fast-developing memory within the amygdala facilitates slower-developing memory within the cerebellum. The current study tested this hypothesis by impairing memory consolidation within the amygdala with inhibition of protein synthesis, transcription, and NMDA receptors in rats. Rats given infusions of anisomycin or DRB into the central amygdala (CeA) immediately after each eyeblink conditioning session were severely impaired in contextual and cued fear conditioning, but were completely unimpaired in eyeblink conditioning. Rats given the NMDA antagonist ifenprodil into the CeA before each eyeblink conditioning session also showed impaired fear conditioning, but no deficit in eyeblink conditioning. The results indicate that memory formation within the CeA is not necessary for its modulation of cerebellar learning mechanisms. The CeA may modulate cerebellar learning and retention through an attentional mechanism that develops within the training sessions. © 2017 Steinmetz et al.; Published by Cold Spring Harbor Laboratory Press.

The Flipped Classroom: An active teaching and learning strategy for making the sessions more interactive and challenging.

Flipping the classroom is a pedagogical model that employs easy to use, readily accessible technology based resources such as video lectures, reading handouts, and practice problems outside the classroom, whereas interactive group-based, problem-solving activities conducted in the classroom. This strategy permits for an extended range of learning activities during the session. Using class time for active learning provides greater opportunity for mentoring and peer to peer collaboration. Instead of spending too much time on delivering lectures, class time can best be utilized by interacting with students, discussing their concerns related to the particular topic to be taught, providing real life examples relevant to the course content, challenging students to think in a broader aspect about complex process and encouraging different team based learning activities.

As part of an institutional program sponsored by the Centre for Teaching Excellence at the Universidad del Norte, Barranquilla, Colombia, we developed an educational research study on two sessions of human anatomy in which we combined team-based learning (TBL) and the use of iPads. Study data included the TBL, assessments applied during the course, student's grades on mid-term examinations and students' perceptions of their experiences. Students reported a positive attitude toward the use of the TBL sessions, and the results showed a significant improvement in their learning between the first and second sessions. Significantly positive correlations (P < 0.05) were obtained between (a) the individual students' readiness test performance 1 and mid-term examination 1, (b) the individual readiness test performances from Session 1 to Session 2, and (c) the group readiness test performances from the first and second sessions. These results point to positive learning experiences for these students. Analyses of the students' reflections on their activities also pointed toward future challenges. © 2014 American Association of Anatomists.

To incorporate learning activities into the weekly 2-hour Drug Information and Literature Evaluation class sessions to improve student ability and confidence in performing course objectives, as well as to assess student perception of the value of these activities. In-class activities that emphasized content and skills taught within class periods were created and implemented. Three different surveys assessing student ability and confidence in completing drug information and literature retrieval and evaluation tasks were administered prior to and following the appropriate class sessions. At the completion of the course, an additional evaluation was administered to assess the students' impressions of the value of the learning activities. Students reported increased ability and confidence in all course objectives. The teaching activities were also stated to be useful in students' learning of the material. Incorporation of weekly learning activities resulted in an improvement in student ability and confidence to perform course objectives. Students considered these activities to be beneficial and to contribute to the completion of course objectives.

2015-04-01

Recent work has demonstrated that functional connectivity between remote brain regions can be modulated by task learning or the performance of an already well-learned task. Here, we investigated the extent to which initial learning and stable performance of a spatial navigation task modulates functional connectivity between subregions of hippocampus and striatum. Subjects actively navigated through a virtual water maze environment and used visual cues to learn the position of a fixed spatial location. Resting-state functional magnetic resonance imaging scans were collected before and after virtual water maze navigation in two scan sessions conducted 1 week apart, with a behavior-only training session in between. There was a large significant reduction in the time taken to intercept the target location during scan session 1 and a small significant reduction during the behavior-only training session. No further reduction was observed during scan session 2. This indicates that scan session 1 represented initial learning and scan session 2 represented stable performance. We observed an increase in functional connectivity between left posterior hippocampus and left dorsal caudate that was specific to scan session 1. Importantly, the magnitude of the increase in functional connectivity was correlated with offline gains in task performance. Our findings suggest cooperative interaction occurs between posterior hippocampus and dorsal caudate during awake rest following the initial phase of spatial navigation learning. Furthermore, we speculate that the increase in functional connectivity observed during awake rest after initial learning might reflect consolidation-related processing. © 2014 Wiley Periodicals, Inc.

Objective: In this study we implemented the “flipped classroom” model to enhance active learning in medical students taking neurosciences module at Aga Khan University, Karachi. Methods: Ninety eight undergraduate medical students participated in this study. The study was conducted from January till March 2017. Study material was provided to students in form of video lecture and reading material for the non-face to face sitting, while face to face time was spent on activities such as case solving, group discussions, and quizzes to consolidate learning under the supervision of faculty. To ensure deeper learning, we used pre- and post-class quizzes, work sheets and blog posts for each session. Student feedback was recorded via a likert scale survey. Results: Eighty four percent students gave positive responses towards utility of flipped classroom in terms of being highly interactive, thought provoking and activity lead learning. Seventy five percent of the class completed the pre-session preparation. Students reported that their queries and misconceptions were cleared in a much better way in the face-to-face session as compared to the traditional setting (4.09 ±1.04). Conclusion: Flipped classroom(FCR) teaching and learning pedagogy is an effective way of enhancing student engagement and active learning. Thus, this pedagogy can be used as an effective tool in medical schools. PMID:29492071

This paper presents a comparison between e-Learning and traditional learning methods of a University course on Health Informatics domain. A pilot research took place among University students who divided on two learning groups, the e-learners and the traditional learners. A comparison of the examinations' marks for the two groups of students was conducted in order to find differences on students' performance. The study results reveal that the students scored almost the same marks independently of the learning procedure. Based on that, it can be assumed that the e-learning courses have the same effectiveness as the in-classroom learning sessions.

Canu, Michael; Duque, Mauricio; de Hosson, Cécile

2017-01-01

Engineering students on control courses lack a deep understanding of equilibrium and stability that are crucial concepts in this discipline. Several studies have shown that students find it difficult to understand simple familiar or academic static equilibrium cases as well as dynamic ones from mechanics even if they know the discipline's criteria and formulae. Our aim is to study the impact of a specific and innovative classroom session, containing well-chosen situations that address students' misconceptions. We propose an example of Active Learning experiment based both on the Didactical Engineering methodology and the Conceptual Fields Theory that aims at promoting a conceptual change in students. The chosen methodology allows, at the same time, a proper design of the student learning activities, an accurate monitoring of the students' rational use during the tasks and provides an internal tool for the evaluation of the session's efficiency. Although the expected starting conceptual change was detected, it would require another activity in order to be reinforced.

2014-01-01

Purpose: At present, transformative learning is one of the most important issues in medical education, since a conventional learning environment is prone to failure due to changing patterns among students. Ethnographic edutainment is a concept that consists of reward, competition, and motivation strategies that be used to effectively engage with learners. Methods: A total 321 first-year medical students took part in ethnographic edutainment sessions in 2011. We defined four preset learning objectives and assigned a term group project using clouding technologies. Participatory evaluation was conducted to assess the delivery of and attitudes towards this method. Results: Career lifestyles in the general population and expected real-life utilization of the final product were used as motivating factors, with competition and rewards provided through a short film contest. Nineteen out of twenty groups (95%) achieved all learning objectives. Females were more satisfied with this activity than males (P<0.001). We found statistically significant differences between lecture-based sessions and field visit sessions, as well as ethnographic edutainment activity sessions and other instructional approaches (P<0.01). The results were consistent in male and female groups. Conclusion: Ethnographic edutainment is well accepted, with higher satisfaction rates than other types of teaching. The concepts of health promotion and the social determinants of health can be learned through ethnographic edutainment activities, which might help train more humanized health professionals.

To describe the implementation of an interprofessional shared learning model designed to promote the development of person-centered healthcare communication skills. Master of social work (MSW) and doctor of physical therapy (DPT) degree students. The model used evidence-based principles of effective healthcare communication and shared learning methods; it was aligned with student learning outcomes contained in MSW and DPT curricula. Students engaged in 3 learning sessions over 2 days. Sessions involved interactive reflective learning, simulated role-modeling with peer assessment, and context-specific practice of communication skills. The perspective of patients/clients was included in each learning activity. Activities were evaluated through narrative feedback. Students valued opportunities to learn directly from each other and from healthcare consumers. Important insights and directions for future interprofessional learning experiences were gleaned from model implementation. The interprofessional shared learning model shows promise as an effective method for developing person-centered communication skills.

Reflecting on workplace-based experiences is necessary for professional development. However, residents need support to raise their awareness of valuable moments for learning and to thoughtfully analyze those learning moments afterwards. From October to December 2012, the authors held a multidisciplinary six-week postgraduate training module focused on general competencies. Residents were randomly assigned to one of four conditions with varying degrees of reflection support; they were offered (1) a smartphone app, (2) coaching group sessions, (3) a combination of both, or (4) neither type of support. The app allowed participants to capture in real time learning moments as a text note, audio recording, picture, or video. Coaching sessions held every two weeks aimed to deepen participants' reflection on captured learning moments. Questionnaire responses and reflection data were compared between conditions to assess the effects of the app and coaching sessions on intensity and frequency of reflection. Sixty-four residents participated. App users reflected more often, captured more learning moments, and reported greater learning progress than nonapp users. Participants who attended coaching sessions were more alert to learning moments and pursued more follow-up learning activities to improve on the general competencies. Those who received both types of support were most alert to these learning moments. A simple mobile app for capturing learning moments shows promise as a tool to support workplace-based learning, especially when combined with coaching sessions. Future research should evaluate these tools on a broader scale and in conjunction with residents' and students' personal digital portfolios.

Mobile technologies offer new opportunities to improve dissection learning. This study examined the effect of using an iPad-based multimedia dissection manual during anatomy laboratory instruction on learner's perception of anatomy dissection activities and use of time. Three experimental dissection tables used iPads and three tables served as a control for two identical sessions. Trained, non-medical school anatomy faculty observers recorded use of resources at two-minute intervals for 20 observations per table. Students completed pre- and post-perception questionnaires. We used descriptive and inferential analyses. Twenty-one control and 22 experimental students participated. Compared with controls, experimental students reported significantly (P < 0.05) less reliance on paper and instructor resources, greater ability to achieve anatomy laboratory objectives, and clarity of the role of dissection in learning anatomy. Experimental students indicated that the iPad helped them in dissection. We observed experimental students more on task (93% vs. 83% of the time) and less likely to be seeking an instructor (2% vs. 32%). The groups received similar attention from instructors (33% vs. 37%). Fifty-nine percent of the time at least one student was looking at the iPad. Groups clustered around the iPad a third of their time. We conclude that the iPad-manual aided learner engagement, achieved instructional objectives, and enhanced the effectiveness and efficiency of dissection education.

Bridging theory and practice: Mixed methods approach to instruction of law and ethics within the pharmaceutical sciences.

PubMed

Wilby, Kyle John; Nasr, Ziad Ghantous

2016-11-01

Background: Professional responsibilities are guided by laws and ethics that must be introduced and mastered within pharmaceutical sciences training. Instructional design to teaching typically introduces concepts in a traditional didactic approach and requires student memorization prior to application within practice settings. Additionally, many centers rely on best practices from abroad, due to lack of locally published laws and guidance documents. Objectives: The aim of this paper was to summarize and critically evaluate a professional skills laboratory designed to enhance learning through diversity in instructional methods relating to pharmacy law and best practices regarding narcotics, controlled medications, and benzodiazepines. Setting: This study took place within the Professional Skills Laboratory at the College of Pharmacy at Qatar University. Method: A total of 25 students participated in a redesigned laboratory session administered by a faculty member, clinical lecturer, teaching assistant, and a professional skills laboratory technician. The laboratory consisted of eight independent stations that students rotated during the 3-h session. Stations were highly interactive in nature and were designed using non-traditional approaches such as charades, role-plays, and reflective drawings. All stations attempted to have students relate learned concepts to practice within Qatar. Main outcome measures: Student perceptions of the laboratory were measured on a post-questionnaire and were summarized descriptively. Using reflection and consensus techniques, two faculty members completed a SWOC (Strengths, Weaknesses, Opportunities, and Challenges) analysis in preparation for future cycles. Results: 100% (25/25) of students somewhat or strongly agreed that their knowledge regarding laws and best practices increased and that their learning experience was enhanced by a mixed-methods approach. A total of 96% (24/25) of students stated that the mixed-methods instructional approach should be continued in the future. The SWOC analysis identified the mixed methods approach and student feedback as strengths and opportunities, while resource shortages and lack of impact assessment were identified as weaknesses and challenges. Conclusion: Creative redesign of instructional methods pertaining to law and best practices was effective to achieve positive student perceptions regarding instructional methods and learning. Future cycles should include rigorous assessment methods to evaluate impact on student learning and practice.

Machine Learning of Fault Friction

We are applying machine learning (ML) techniques to continuous acoustic emission (AE) data from laboratory earthquake experiments. Our goal is to apply explicit ML methods to this acoustic datathe AE in order to infer frictional properties of a laboratory fault. The experiment is a double direct shear apparatus comprised of fault blocks surrounding fault gouge comprised of glass beads or quartz powder. Fault characteristics are recorded, including shear stress, applied load (bulk friction = shear stress/normal load) and shear velocity. The raw acoustic signal is continuously recorded. We rely on explicit decision tree approaches (Random Forest and Gradient Boosted Trees) that allow us to identify important features linked to the fault friction. A training procedure that employs both the AE and the recorded shear stress from the experiment is first conducted. Then, testing takes place on data the algorithm has never seen before, using only the continuous AE signal. We find that these methods provide rich information regarding frictional processes during slip (Rouet-Leduc et al., 2017a; Hulbert et al., 2017). In addition, similar machine learning approaches predict failure times, as well as slip magnitudes in some cases. We find that these methods work for both stick slip and slow slip experiments, for periodic slip and for aperiodic slip. We also derive a fundamental relationship between the AE and the friction describing the frictional behavior of any earthquake slip cycle in a given experiment (Rouet-Leduc et al., 2017b). Our goal is to ultimately scale these approaches to Earth geophysical data to probe fault friction. References Rouet-Leduc, B., C. Hulbert, N. Lubbers, K. Barros, C. Humphreys and P. A.

Patients with Korsakoff's syndrome show devastating amnesia and executive deficits. Consequently, the ability to perform instrumental activities such as making coffee is frequently diminished. It is currently unknown whether patients with Korsakoff's syndrome are able to (re)learn instrumental activities. A good candidate for an effective teaching technique in Korsakoff's syndrome is errorless learning as it is based on intact implicit memory functioning. Therefore, the aim of the current study was two-fold: to investigate whether patients with Korsakoff's syndrome are able to (re)learn instrumental activities, and to compare the effectiveness of errorless learning with trial and error learning in the acquisition and maintenance of an instrumental activity, namely using a washing machine to do the laundry. Whereas initial learning performance in the errorless learning condition was superior, both intervention techniques resulted in similar improvement over eight learning sessions. Moreover, performance in a different spatial layout showed a comparable improvement. Notably, in follow-up sessions starting after four weeks without practice, performance was still elevated in the errorless learning condition, but not in the trial and error condition. The current study demonstrates that (re)learning and maintenance of an instrumental activity is possible in patients with Korsakoff's syndrome.

The design of optimal courses for obstetric undergraduate teaching is a relevant question. This study evaluates two different designs of simulator-based learning activity on childbirth with regard to respect to the patient, obstetric manoeuvres, interpretation of cardiotocography tracings (CTG) and infection prevention. This randomised experimental study which differs in the content of their briefing sessions consisted of two groups of undergraduate students, who performed two simulator-based learning activities on childbirth. The first briefing session included the observations of a properly performed scenario according to Spanish clinical practice guidelines on care in normal childbirth by the teachers whereas the second group did not include the observations of a properly performed scenario, and the students observed it only after the simulation process. The group that observed a properly performed scenario after the simulation obtained worse grades during the simulation, but better grades during the debriefing and evaluation. Simulator use in childbirth may be more fruitful when the medical students observe correct performance at the completion of the scenario compared to that at the start of the scenario. Impact statement What is already known on this subject? There is a scarcity of literature about the design of optimal high-fidelity simulation training in childbirth. It is known that preparing simulator-based learning activities is a complex process. Simulator-based learning includes the following steps: briefing, simulation, debriefing and evaluation. The most important part of high-fidelity simulations is the debriefing. A good briefing and simulation are of high relevance in order to have a fruitful debriefing session. What do the results of this study add? Our study describes a full simulator-based learning activity on childbirth that can be reproduced in similar facilities. The findings of this study add that high-fidelity simulation training in childbirth is favoured by a short briefing session and an abrupt start to the scenario, rather than a long briefing session that includes direct instruction in the scenario. What are the implications of these findings for clinical practice and/or further research? The findings of this study reveal what to include in the briefing of simulator-based learning activities on childbirth. These findings have implications in medical teaching and in medical practice.

To present a multiple-instructor, active-learning strategy in the undergraduate medical curriculum. This educational research is a descriptive one. Shared teaching sessions, were designed for undergraduate medical students in six organ-system based courses. Sessions that involved in-class discussions of integrated clinical cases were designed implemented and moderated by at least 3 faculties (clinicians and basic scientists). The participants in this study include the basic sciences medical students of The Tehran University of Medical Sciences. Students' reactions were assessed using an immediate post-session evaluation form on a 5-point Likert scale. Six two-hour sessions for 2 cohorts of students, 2013 and 2014 medical students during their two first years of study were implemented from April 2014 to March 2015. 17 faculty members participated in the program, 21 cases were designed, and participation average was 60 % at 6 sessions. Students were highly appreciative of this strategy. The majority of students in each course strongly agreed that this learning practice positively contributed to their learning (78%) and provided better understanding and application of the material learned in an integrated classroom course (74%). They believed that the sessions affected their view about medicine (73%), and should be continued in future courses (80%). The percentage demonstrates the average of all courses. The program helped the students learn how to apply basic sciences concepts to clinical medicine. Evaluation of the program indicated that students found the sessions beneficial to their learning.

Geoscience Education and Cognition Research at George Mason University

Cognition research in Geoscience is the focus of a small group of faculty from the College of Science and the College of Education and Human Development at George Mason University. We approached this research when we were involved in an Institution-wide effort to assess critical thinking, one of the competencies mandated for evaluation by the State Council of Higher Education of Virginia. Our group started spontaneously and informally from personal interests and enthusiasm for what and how our students are learning about Geology and in general about science. We want to understand what our students bring to the course, their attitude towards science, their knowledge of the scientific enterprise and preconceived ideas—and what our students take away from the course, beyond the course content. We believe that, with the support of cognitive science, we can improve the learning experience and therefore enhance the learning outcomes for science and non-science majors alike. Our Institution offers introductory Physical and Historical Geology classes populated primarily by non-science-major undergraduates. Geology lectures range in size from 90 to over 220 students per session per semester, with laboratory sessions averaging 27 students per session. With this large student population, it is necessary to use research tools that give us valuable information about student cognition, while being efficient in terms of time use and logistics. Some examples of our work include critical readings on Geoscience topics, surveys on students’ understanding of science as a way of knowing, exercises with built-in self-efficacy assessments, and concept mapping. The common denominator among these tools is that they are calibrated to address one or more of the higher levels in the revised Bloom’s Taxonomy of the Cognitive Domain, which form a complex assessment of student learning processes. These tools, once refined, can provide us with a better view of how our students learn in Geology. While we are still working on our data and fine-tuning our research, we have already started to apply the results to how we teach Physical Geology in the laboratory. For example, we have designed a new laboratory workbook (Kysar-Mattietti and Verardo, 2009), and, this Fall 2009, a few sessions of Physical Geology laboratory are experimenting with enhancing students’ awareness of their learning. We have recently started to publish our work by presenting it at meetings and submitting journal articles, in this sense presenting ourselves officially as a group. At present, our group is not supported as a research entity per se, though the Center for Teaching Excellence and the College of Education and Human Development is providing most of the resources needed at this stage. At this point, we are looking for ways to sustain and acquire visibility and support for our group within our own Institution and to establish connections with other Institutions of higher education where there are programs for research in “geocognition”.

Active learning with clickers is a common approach in high-enrollment, lecture-based courses in science, technology, engineering, and mathematics. In this study, we describe the procedures that faculty at one institution used when implementing clicker-based active learning, and how they situated these activities in their class sessions. Using a mixed-methods approach, we categorized faculty into four implementation styles based on quantitative observation data and conducted qualitative interviews to further understand why faculty used these styles. We found that faculty tended to use similar procedures when implementing a clicker activity, but differed on how they situated the clicker-based active learning into their courses. These variations were attributed to different faculty goals for using clicker-based active learning, with some using it to engage students at specific time points throughout their class sessions and others who selected it as the best way to teach a concept from several possible teaching techniques. Future research should continue to investigate and describe how active-learning strategies from literature may differ from what is being implemented.

SMART Board(TM) and RealProducer(R) Plus technologies were used to develop a series of narrated pre-lab introductory online lectures. Smartboard slides were created by capturing images from internet pages and power point slides, then annotated and saved as web pages using smartboard technology. Short audio files were recorded using the RealProducer Plus software which were then linked to individual slides. WebCT was used to deliver the online laboratory. Students in an Introductory Astronomy of the Solar System Online laboratory used the lectures to prepare for laboratory exercises. The narrated pre-lab lectures were added to six out of eight suitable laboratory exercises. A survey was given to the students to research their online laboratory experience, in general, and the impact of the narrated smartboard lectures on their learning success, specifically. Data were collected for two accelerated sessions. Results show that students find the online laboratory equally hard or harder than a separate online lecture. The accelerated format created great time pressure which negatively affected their study habits. About half of the students used the narrated pre-lab lectures consistently. Preliminary findings show that lab scores in the accelerated sessions were brought up to the level of full semester courses.

Team-based learning (TBL) is used in undergraduate medical education to facilitate higher-order content learning, promote learner engagement and collaboration, and foster positive learner attitudes. There is a paucity of data on the use of TBL in graduate medical education. Our aim was to assess resident engagement, learning, and faculty/resident satisfaction with TBL in internal medicine residency ambulatory education. Survey and nominal group technique methodologies were used to assess learner engagement and faculty/resident satisfaction. We assessed medical learning using individual (IRAT) and group (GRAT) readiness assurance tests. Residents (N = 111) involved in TBL sessions reported contributing to group discussions and actively discussing the subject material with other residents. Faculty echoed similar responses, and residents and faculty reported a preference for future teaching sessions to be offered using the TBL pedagogy. The average GRAT score was significantly higher than the average IRAT score by 22%. Feedback from our nominal group technique rank ordered the following TBL strengths by both residents and faculty: (1) interactive format, (2) content of sessions, and (3) competitive nature of sessions. We successfully implemented TBL pedagogy in the internal medicine ambulatory residency curriculum, with learning focused on the care of patients in the ambulatory setting. TBL resulted in active resident engagement, facilitated group learning, and increased satisfaction by residents and faculty. To our knowledge this is the first study that implemented a TBL program in an internal medicine residency curriculum.

Medical simulation is relatively a novel technology widely utilized for teaching and assessing students clinical skills. Students and faculty face many challenges when simulation sessions are introduced into undergraduate curriculum. The aim of this study is to obtain the opinion of undergraduate medical students and our faculty regarding the role of simulation in undergraduate curriculum, the simulation modalities used, and the perceived barriers in implementing simulation sessions. A self-administered pilot tested questionnaire with 18 items using a 5-point Likert scale was distributed to undergraduate male (n = 125) and female students (n = 70) as well as to the faculty members (n = 14) at King Fahad Medical City, King Saud Bin Abdul Aziz University of Health Sciences, Saudi Arabia, to respond. Survey elements addressed the role of simulation, simulation modalities used, and perceived challenges to implementation of simulation sessions. Various learning outcomes are achieved and improved through the technology enhanced simulation sessions such as communication skills, diagnostic skills, procedural skills, self-confidence, and integration of basic and clinical sciences. The use of high fidelity simulators, simulated patients and task trainers was more desirable by our students and faculty for teaching and learning as well as an evaluation tool. According to most of the students', institutional support in terms of resources, staff and duration of sessions was adequate. However, motivation to participate in the sessions and provision of adequate feedback by the staff was a constraint. The use of simulation laboratory is of great benefit to the students and a great teaching tool for the staff to ensure students learn various skills.

Ripple-triggered stimulation of the locus coeruleus during post-learning sleep disrupts ripple/spindle coupling and impairs memory consolidation.

Experience-induced replay of neuronal ensembles occurs during hippocampal high-frequency oscillations, or ripples. Post-learning increase in ripple rate is predictive of memory recall, while ripple disruption impairs learning. Ripples may thus present a fundamental component of a neurophysiological mechanism of memory consolidation. In addition to system-level local and cross-regional interactions, a consolidation mechanism involves stabilization of memory representations at the synaptic level. Synaptic plasticity within experience-activated neuronal networks is facilitated by noradrenaline release from the axon terminals of the locus coeruleus (LC). Here, to better understand interactions between the system and synaptic mechanisms underlying "off-line" consolidation, we examined the effects of ripple-associated LC activation on hippocampal and cortical activity and on spatial memory. Rats were trained on a radial maze; after each daily learning session neural activity was monitored for 1 h via implanted electrode arrays. Immediately following "on-line" detection of ripple, a brief train of electrical pulses (0.05 mA) was applied to LC. Low-frequency (20 Hz) stimulation had no effect on spatial learning, while higher-frequency (100 Hz) trains transiently blocked generation of ripple-associated cortical spindles and caused a reference memory deficit. Suppression of synchronous ripple/spindle events appears to interfere with hippocampal-cortical communication, thereby reducing the efficiency of "off-line" memory consolidation. © 2016 Novitskaya et al.; Published by Cold Spring Harbor Laboratory Press.

Active learning or self-learning increases the student's participation and commitment to his studies; these conditions are necessary to improve academic performance. An intervention has been designed based on the experience in the use of clickers in other universities, but without the actual technology. This work has been performed in the School of Nursing affiliated to the University of Malaga (UMA) on students enrolled in their second year of Degree in Adult Nursing Course I. Three sessions of multiple-choice questions were scheduled on the subject "distance learning" in which master classes were not taught. The answers were collected on paper templates. We wanted to determine the degree of relationship between the attendance of sessions and the results obtained by students in the final examination of the subject, as well as, the questions dedicated to assess the "distance learning" matter. The results support a significant statistical difference in the correct answers by students according to the number of sessions attended. These differences are highest among students who did not attend any session and those who attended the three planned sessions.

Virtual patients (VPs) have been recently integrated within different learning activities. To compare between the effect of using VPs in a collaborative learning activity and using VPs in an independent learning activity on students' knowledge acquisition, retention and transfer. For two different topics, respectively 82 and 76 dental students participated in teaching, learning and assessment sessions with VPs. Students from a female campus and from a male campus have been randomly assigned to condition (collaborative and independent), yielding four experimental groups. Each group received a lecture followed by a learning session using two VPs per topic. Students were administrated immediate and delayed written tests as well as transfer tests using two VPs to assess their knowledge in diagnosis and treatment. For the treatment items of the immediate and delayed written tests, females outperformed males in the collaborative VP group but not in the independent VP group. On the female campus, the use of VPs in a collaborative learning activity is more effective than its use as an independent learning activity in enhancing students' knowledge acquisition and retention. However, the collaborative use of VPs by itself is not enough to produce consistent results across different groups of students and attention should be given to all the factors that would affect students' interaction.

Implementation of the peer-led team-learning instructional model as a stopgap measure improves student achievement for students opting out of laboratory.

In entry-level university courses in science, technology, engineering, and mathematics fields, students participating in associated laboratory sessions generally do better than those who have no related lab classes. This is a problem when, for various reasons, not enough lab sections can be offered for students and/or when students opt out of optional available lab courses. Faced with such a situation, this study evaluated the efficacy of the peer-led team-learning (PLTL) instructional model as a potential method for narrowing the achievement gap among undergraduate students electing not to enroll in an optional laboratory component of an introductory biology course. In peer-led workshops, small groups of students participated in solving problems and other activities that encouraged active learning. Students led by peer leaders attained significantly higher exam and final course grades in introductory biology than comparable students not participating in PLTL. Among the introductory biology students who opted not to enroll in the optional lab course, those who participated in PLTL averaged more than a letter grade higher than those who did not. This difference was statistically significant, and the PLTL workshops almost entirely closed the achievement gap in lecture exam and final grades for students who did not take the lab. © 2015 J. J.

Behavioural training through positive reinforcement techniques is a well-recognised refinement to laboratory animal welfare. Behavioural neuroscience research requires subjects to be trained to perform repetitions of specific behaviours for food/fluid reward. Some animals fail to perform at a sufficient level, limiting the amount of data that can be collected and increasing the number of animals required for each study. We have implemented automated positive reinforcement training systems (comprising a button press task with variable levels of difficulty using LED cues and a fluid reward) at the breeding facility and research facility, to compare performance across these different settings, to pre-screen animals for selection and refine training protocols. Animals learned 1- and 4-choice button tasks within weeks of home enclosure training, with some inter-individual differences. High performance levels (∼200-300 trials per 60min session at ∼80% correct) were obtained without food or fluid restriction. Moreover, training quickly transferred to a laboratory version of the task. Animals that acquired the task at the breeding facility subsequently performed better both in early home enclosure sessions upon arrival at the research facility, and also in laboratory sessions. Automated systems at the breeding facility may be used to pre-screen animals for suitability for behavioural neuroscience research. In combination with conventional training, both the breeding and research facility systems facilitate acquisition and transference of learning. Automated systems have the potential to refine training protocols and minimise requirements for food/fluid control. Copyright © 2017 The Authors. Published by Elsevier B.V. All rights reserved.

Testing The Scale-up Approach To Introductory Astronomy

Kregenow, Julia M.; Keller, L.; Rogers, M.; Romero, D.

2008-09-01

Ithaca College physics department has begun transforming our general education astronomy courses into hands-on, active-learning courses from the previous lecture-based format. We are using the SCALE-UP model (Student Centered Activities for Large Enrollment University Programs) pioneered at North Carolina State University. Expanding on the successes of Studio Physics (developed at RPI), which exchanges traditionally separate lecture/recitation/ laboratory sessions for one dynamic, active-learning environment for approximately 40 students, SCALE-UP extends this model to accommodate 100+ students by using large round tables creating naturally smaller groups of students. Classes meet three times per week with each class blending lecture, hands-on activities, group problem solving, and the use of student polling devices. We are testing whether this mode of teaching astronomy will lead to a better understanding of astronomy and the nature of science. Applying this approach in both the SCALE-UP classroom (90 students) and a traditional lecture classroom (45 students) in spring 2008, we report on our early results and lessons learned after one semester. We also discuss some of our lingering implementation questions and issues, such as: whether to use the same or different instructor in two parallel sections, requiring textbook reading, reading quizzes, on-line homework and activities, how much math to include, development of hands-on activities, and culling the typically overpacked intro astronomy syllabus.

Within the framework of MIT's course 1.00: Introduction to Computers and Engineering Problem Solving, this paper describes an innovative project entitled: Studio 1.00 that integrates lectures with in-class demonstrations, active learning sessions, and on-task feedback, through the use of wireless laptop computers. This paper also describes a related evaluation study that investigated the effectiveness of different instructional strategies, comparing traditional teaching with two models of the studio format. Students' learning outcomes, specifically, their final grades and conceptual understanding of computational methods and programming, were examined. Findings indicated that Studio-1.00, in both its extensive- and partial-active learning modes, enhanced students' learning outcomes in Java programming. Comparing to the traditional courses, more students in the studio courses received "A" as their final grade and less failed. Moreover, students who regularly attended the active learning sessions were able to conceptualize programming principles better than their peers. We have also found two weaknesses in the teaching format of Studio-1.00 that can guide future versions of the course.

Cultural Norms of Clinical Simulation in Undergraduate Nursing Education

PubMed Central

2015-01-01

Simulated practice of clinical skills has occurred in skills laboratories for generations, and there is strong evidence to support high-fidelity clinical simulation as an effective tool for learning performance-based skills. What are less known are the processes within clinical simulation environments that facilitate the learning of socially bound and integrated components of nursing practice. Our purpose in this study was to ethnographically describe the situated learning within a simulation laboratory for baccalaureate nursing students within the western United States. We gathered and analyzed data from observations of simulation sessions as well as interviews with students and faculty to produce a rich contextualization of the relationships, beliefs, practices, environmental factors, and theoretical underpinnings encoded in cultural norms of the students’ situated practice within simulation. Our findings add to the evidence linking learning in simulation to the development of broad practice-based skills and clinical reasoning for undergraduate nursing students. PMID:28462300

The purpose of this article is to describe the implementation of a team-based learning (TBL) approach in a removable denture prosthesis (RDP) module and present the results of students' performance in individual and group TBL activities and exam scores, students' experience with TBL and end of course evaluations, and faculty feedback. Course material at the College of Dentistry, University of Sharjah, United Arab Emirates, was transformed into seven conventional lectures and seven TBL sessions. Each TBL session consisted of pre-assigned reading (self-directed learning), in-class individual and group readiness tests (accountability), team problem-solving of patient RDP cases, and faculty-led class discussion (knowledge application). The course was assessed through scores from TBL session activities and course examinations, student satisfaction survey, and faculty feedback. Course grades were found to be higher using the TBL method then the traditional lecture-based method. Student evaluation data and faculty response indicated strong support for TBL as it was implemented in the course. The faculty noted a higher level of student engagement with team learning than in conventional class lecturing. TBL is an active-learning instructional strategy for courses with high student-to-faculty ratios. This approach provides regular feedback and the opportunity for students to develop higher reasoning skills.

Repeated exposure to a same-sex resident stranger enhances subsequent indications of active coping that generalize across multiple contexts in intruder male mice. Here we investigate female mice for comparable learning to cope training effects. Stress coping research focused on females is important because stress related mood and anxiety disorders are more prevalent in women than men. Female mice were monitored for coping behavior in open-field, object-exploration, and tail-suspension tests conducted after repeated exposure to a same-sex resident stranger. During repeated exposure sessions of training staged in the resident's home cage, behavioral measures of aggression and risk assessment were collected and plasma measures of the stress hormone corticosterone were obtained from separate samples of mice. Repeated exposure to a same-sex resident stranger subsequently enhanced active coping behavior exemplified by diminished freezing and increased center entries in the open-field, shorter object-exploration latencies, and a tendency toward decreased immobility on tail-suspension tests. Open-field locomotion considered as an index of non-specific activity was not increased by repeated sessions of exposure and did not correlate significantly with any measure of active coping. During repeated sessions of exposure to a same-sex resident stranger, risk assessment behavior and consistent but limited aggression occurred and corticosterone responses increased over repeated sessions. Exposure to a same-sex resident stranger is mildly stressful and promotes learning to actively cope in mice assessed in three different contexts. Copyright © 2018. Published by Elsevier Ltd.

Individuals with developmental disabilities may engage in automatically reinforced behaviors that may interfere with learning opportunities. Manipulation of motivating operations has been shown to reduce automatically maintained behavior in some individuals. Considering behavioral indicators of satiation may assist in identifying the point at which an abolishing operation has begun to effect behavior. The purpose of this study was to evaluate the effects of pre-session satiation of automatic reinforcement on subsequent levels of stereotypy and activity engagement during group activities for three males ages 5 to 13 years with developmental disabilities. Following functional analyses with analogue conditions, an alternating treatment design compared a pre-session access to stereotypy condition with a no-pre-session access condition prior to group activity sessions. Results indicated that pre-session satiation of the putative reinforcer produced by stereotypy was effective in decreasing stereotypy and increasing activity engagement during subsequent group activities for all participants. These findings add to the literature supporting the effectiveness of abolishing operations to decrease automatically maintained stereotypy. © The Author(s) 2013.

EFFECTIVENESS OF PROBLEM BASED LEARNING AS A STRATEGY TO FOSTER PROBLEM SOLVING AND CRITICAL REASONING SKILLS AMONG MEDICAL STUDENTS.

Asad, Munazza; Iqbal, Khadija; Sabir, Mohammad

2015-01-01

Problem based learning (PBL) is an instructional approach that utilizes problems or cases as a context for students to acquire problem solving skills. It promotes communication skills, active learning, and critical thinking skills. It encourages peer teaching and active participation in a group. It was a cross-sectional study conducted at Al Nafees Medical College, Isra University, Islamabad, in one month duration. This study was conducted on 193 students of both 1st and 2nd year MBBS. Each PBL consists of three sessions, spaced by 2-3 days. In the first session students were provided a PBL case developed by both basic and clinical science faculty. In Session 2 (group discussion), they share, integrate their knowledge with the group and Wrap up (third session), was concluded at the end. A questionnaire based survey was conducted to find out overall effectiveness of PBL sessions. Teaching through PBLs greatly improved the problem solving and critical reasoning skills with 60% students of first year and 71% of 2nd year agreeing that the acquisition of knowledge and its application in solving multiple choice questions (MCQs) was greatly improved by these sessions. They observed that their self-directed learning, intrinsic motivation and skills to relate basic concepts with clinical reasoning which involves higher order thinking have greatly enhanced. Students found PBLs as an effective strategy to promote teamwork and critical thinking skills. PBL is an effective method to improve critical thinking and problem solving skills among medical students.

To assess whether two persons with multiple disabilities could learn a work activity (i.e., assembling trolley wheels) with the support of a technology system. After an initial baseline, the study compared the effects of intervention sessions relying on the technology system (which called the participants to the different workstations and provided feedback and final stimulation) with the effects of intervention sessions carried out without technology. The two types of intervention sessions were conducted according to an alternating treatments design. Eventually, only intervention sessions relying on the technology system were used. Both participants managed to assemble wheels independently during intervention sessions relying on the technology system while they failed during sessions without the system. Their performance was strengthened during the final part of the study, in which only sessions with the system occurred. Technology may be critical in helping persons with multiple disabilities manage multi-step work activities.

Purpose: The acquisition of clinical-technical skills is of particular importance for the doctors of tomorrow. Procedural skills are often trained for the first time in skills laboratories, which provide a sheltered learning environment. However, costs to implement and maintain skills laboratories are considerably high. Therefore, the purpose of the present study was to investigate students’ patterns of attendance of voluntary skills-lab training sessions and thereby answer the following question: Is it possible to measure an effect of the theoretical construct related to motivational psychology described in the literature – ‘Assessment drives learning’ – reflected in patterns of attendance at voluntary skills-lab training sessions? By answering this question, design recommendations for curriculum planning and resource management should be derived. Method: A retrospective, descriptive analysis of student skills-lab attendance related to voluntary basic and voluntary advanced skills-lab sessions was conducted. The attendance patterns of a total of 340 third-year medical students in different successive year groups from the Medical Faculty at the University of Heidelberg were assessed. Results: Students showed a preference for voluntary basic skills-lab training sessions, which were relevant to clinical skills assessment, especially at the beginning and at the end of the term. Voluntary advanced skills-lab training sessions without reference to clinical skills assessment were used especially at the beginning of the term, but declined towards the end of term. Conclusion: The results show a clear influence of assessments on students’ attendance at skills-lab training sessions. First recommendations for curriculum design and resource management will be described. Nevertheless, further prospective research studies will be necessary to gain a more comprehensive understanding of the motivational factors impacting students’ utilisation of voluntary skills-lab training in order to reach a sufficient concordance between students’ requirements and faculty offers, as well as resource management.

Case-based learning (CBL) is an interactive student-centered exploration of real life situations. This paper describes the use of CBL as an educational strategy for promoting active learning in microbiology. CBL was introduced in the microbiology curriculum for the second year medical students after an orientation program for faculty and students. After intervention, the average student scores in CBL topics were compared with scores obtained in lecture topics. An attempt was also made to find the effect of CBL on the academic performance. Student and faculty perception on CBL were also recorded. In a cross sectional survey conducted to assess the effectiveness of CBL, students responded that, apart from helping them acquire substantive knowledge in microbiology, CBL sessions enhanced their analytic, collaborative, and communication skills. The block examination scores in CBL topics were significantly higher than those obtained for lecture topics. Faculty rated the process to be highly effective in stimulating student interest and long term retention of microbiology knowledge. The student scores were significantly higher in the group that used CBL, compared to the group that had not used CBL as a learning strategy. Our experience indicated that CBL sessions enhanced active learning in microbiology. More frequent use of CBL sessions would not only help the student gain requisite knowledge in microbiology but also enhance their analytic and communication skills.

The development and assessment of constructivist-based curriculum changes in a university general biology laboratory course

This study describes the processes involved in transforming the curriculum of the second semester general biology laboratory course for science majors, BSC 111L, at the University of Southern Mississippi from one based on the behaviorist model of teaching and learning to one based on the constructivist model. The study encompasses pilot and research phases. During the pilot phase conducted fall semester of 1997, the researcher presented to graduate teaching assistants an overview of the need for curriculum reform and some of the theoretical underpinnings for the movement. The researcher worked with all of the general biology teaching assistants to determine factors they considered supportive of the effort, identified specific goals and exercises, and developed a mission statement. The researcher then worked with two of the teaching assistants to write the new curriculum materials and pilot them in a designated laboratory section each week. During the research phase, the researcher facilitated the use of constructivist teaching methods and interviewed the teaching assistants during weekly group meetings. The researcher videotaped and observed the laboratories at various times throughout spring semester of 1998. Student responses to survey questions about the laboratories were collected during the observation sessions. Data derived from self-assessments on teaching beliefs completed by the teaching assistants, interview transcripts, videotaped laboratory sessions, and student surveys were used to assess the effectiveness of the new curriculum and the intervention program. It was observed that despite being given the same instructions, curriculum, and materials, each teaching assistant conducted his laboratory section in a unique way and rarely conducted the complete laboratory in the intended manner. It was also observed that one TA in particular needed more training in interpersonal skill development and content than was provided during the weekly intervention sessions. However, it was evident that constructivist teaching methods were being learned and that constructivist goals were being realized. Strengths and weaknesses of the curriculum materials were identified and extensive revisions were made by the researcher prior to the next semester. Finally, recommendations pertinent to the student survey used in this study (the Student Outcome Assessment Rubric) were made, and the need for more pedagogical instruction for teaching assistants and a mechanism to integrate lecture materials to the laboratory experience was described.

The value of problem-based learning (PBL) in the preclinical years of medical school has been described widely in the literature. This study evaluates student and faculty perceptions of PBL during the clinical years of medical school, on a family medicine clerkship. Students used a 4-point scale to rate clerkship educational components on how well learning was facilitated. Faculty narratives of their perceptions of PBL were reviewed. Educational components that involved active learning by students--clinical activity, independent learning, and PBL tutorials--were ranked highest by students. Faculty perceived that PBL on the clerkship simulated "real-life" learning, included more behavioral and population issues, and provided substantial blocks of student contact time for improved student evaluation. Students and faculty in a family medicine clerkship ranked PBL sessions higher than any other nonclinical component of the clerkship. In addition to providing students with opportunities for self-directed learning, the PBL sessions provide faculty with more contact time with students, thereby enhancing the assessment of students' learning and progress.

Experiments on rats trained passive avoidance task showed that N-phenyl-acetyl-L-prolyl-glycyl ethyl ester, peptide analog of piracetam (GVS-111, Noopept) after oral administration retained antiamnesic activity previously observed after its parenteral administration. Effective doses were 0.5-10 mg/kg. Experiments on a specially-developed model of active avoidance (massive one-session learning schedule) showed that GVS-111 stimulated one-session learning after single administration, while after repeated administration it increased the number of successful learners among those animals who failed after initial training. In this respect, GVS-111 principally differs from its main metabolite cycloprolylglycine and standard nootropic piracetam.

2016-07-19

Lectures continue to be an efficient and standardised way to deliver information to large groups of students. It has been well documented that students prefer interactive lectures, based on active learning principles, to didactic teaching in the large group setting. Despite this, it is often the case than many students do not engage with active learning tasks and attempts at interaction. By exploring student experiences, expectations and how they use lectures in their learning we will provide recommendations for faculty to support student learning both in the lecture theatre and during personal study time. This research employed a hermeneutic phenomenological approach. Three focus groups, consisting of 19 students in total, were used to explore the experiences of second year medical students in large group teaching sessions. Using generic thematic data analysis, these accounts have been developed into a meaningful account of experience. This study found there to be a well-established learning culture amongst students and with it, expectations as to the format of teaching sessions. Furthermore, there were set perceptions about the student role within the learning environment which had many implications, including the way that innovative teaching methods were received. Student learning was perceived to take place outside the lecture theatre, with a large emphasis placed on creating resources that can be taken away to use in personal study time. Presented here is a constructive review of reasons for student participation, interaction and engagement in large group teaching sessions. Based on this are recommendations constructed with the view to aid educators in engaging students within this setting. Short term, educators can implement strategies that monopolise on the established learning culture of students to encourage engagement with active learning strategies. Long term, it would be beneficial for educators to consider ways to shift the current student learning culture to one that embraces an active learning curriculum.

Sleep modulates motor learning, but its detailed impact on performance curves remains to be fully characterized. This study aimed to further determine the impact of brief daytime periods of NREM sleep on 'offline' (task discontinuation after initial training) and 'on-task' (performance within the test session) changes in motor skill performance (finger tapping task). In a mixed design (combined parallel group and repeated measures) sleep laboratory study (n=17 'active' wake vs. sleep, n=19 'passive' wake vs. sleep), performance curves were assessed prior to and after a 90min period containing either sleep, active or passive wakefulness. We observed a highly significant, but state- (that is, sleep/wake)-independent early offline gain and improved on-task performance after sleep in comparison to wakefulness. Exploratory curve fitting suggested that the observed sleep effect most likely emerged from an interaction of training-induced improvement and detrimental 'time-on-task' processes, such as fatigue. Our results indicate that brief periods of NREM sleep do not promote early offline gains but subsequent on-task performance in motor skill learning. Copyright © 2017 Elsevier Inc.

What Happens in Session Doesn't Stay in Session: Changes within Exposures Predict Subsequent Improvement and Dropout

Norton, Peter J.; Hayes-Skelton, Sarah A.; Klenck, Suzanne C.

2011-01-01

Previous exposure therapy research has suggested potential differences in emotional processing at different points in treatment (Hayes, Hope, & Heimberg, 2008). For example, indicators of emotional processing may be more related to outcome during the later exposure sessions than during the initial session. This is consistent with a growing body of psychotherapy research highlighting the importance of timing and change processes across therapy. The current study examined whether the learning-but-not-benefiting hypothesis is observed in a group based intervention for clients with a range of anxiety disorders. It was hypothesized that activation and within session habituation during later, but not the initial exposure session, would be related to outcome, whereas activation and within session habituation during the first session would be related to dropout status. Results revealed that lower activation and less habituation during the first exposure was associated with increased treatment discontinuation. Second, lower peak and, to a lesser extent greater activation and habituation, during exposures were generally associated with better treatment outcomes. These findings highlight the importance of examining the complexities and timing of the exposure process. PMID:21419597

Language effects in second-language learners: A longitudinal electrophysiological study of spanish classroom learning.

How do the neural mechanisms involved in word recognition evolve over the course of word learning in adult learners of a new second language? The current study sought to closely track language effects, which are differences in electrophysiological indices of word processing between one's native and second languages, in beginning university learners over the course of a single semester of learning. Monolingual L1 English-speakers enrolled in introductory Spanish were first trained on a list of 228 Spanish words chosen from the vocabulary to be learned in class. Behavioral data from the training session and the following experimental sessions spaced over the course of the semester showed expected learning effects. In the three laboratory sessions participants read words in three lists (English, Spanish and mixed) while performing a go/no-go lexical decision task in which event-related potentials (ERPs) were recorded. As observed in previous studies there were ERP language effects with larger N400s to native than second language words. Importantly, this difference declined over the course of L2 learning with N400 amplitude increasing for new second language words. These results suggest that even over a single semester of learning that new second language words are rapidly incorporated into the word recognition system and begin to take on lexical and semantic properties similar to native language words. Moreover, the results suggest that electrophysiological measures can be used as sensitive measures for tracking the acquisition of new linguistic knowledge. Copyright © 2016 Elsevier B.V.

2012-07-01

Action words referring to face, arm or leg actions activate areas along the motor strip that also control the planning and execution of the actions specified by the words. This electroencephalogram (EEG) study aimed to test the learning profile of this language-induced motor activity. Participants were trained to associate novel verbal stimuli to videos of object-oriented hand and arm movements or animated visual images on two consecutive days. Each training session was preceded and followed by a test-session with isolated videos and verbal stimuli. We measured motor-related brain activity (reflected by a desynchronization in the μ frequency bands; 8-12 Hz range) localized at centro-parietal and fronto-central electrodes. We compared activity from viewing the videos to activity resulting from processing the language stimuli only. At centro-parietal electrodes, stable action-related μ suppression was observed during viewing of videos in each test-session of the two days. For processing of verbal stimuli associated with motor actions, a similar pattern of activity was evident only in the second test-session of Day 1. Over the fronto-central regions, μ suppression was observed in the second test-session of Day 2 for the videos and in the second test-session of Day 1 for the verbal stimuli. Whereas the centro-parietal μ suppression can be attributed to motor events actually experienced during training, the fronto-central μ suppression seems to serve as a convergence zone that mediates underspecified motor information. Consequently, sensory-motor reactivations through which concepts are comprehended seem to differ in neural dynamics from those implicated in their acquisition. Copyright © 2011 Elsevier Srl.

Cross-modal transfer occurs when learning established with a stimulus from one sensory modality facilitates subsequent learning with a new stimulus from a different sensory modality. The current study examined neuronal correlates of cross-modal transfer of Pavlovian eyeblink conditioning in rats. Neuronal activity was recorded from tetrodes within the anterior interpositus nucleus (IPN) of the cerebellum and basilar pontine nucleus (PN) during different phases of training. After stimulus pre-exposure and unpaired training sessions with a tone conditioned stimulus (CS), light CS, and periorbital stimulation unconditioned stimulus (US), rats received associative training with one of the CSs and the US (CS1-US). Training then continued on the same day with the other CS to assess cross-modal transfer (CS2-US). The final training session included associative training with both CSs on separate trials to establish stronger cross-modal transfer (CS1/CS2). Neurons in the IPN and PN showed primarily unimodal responses during pre-training sessions. Learning-related facilitation of activity correlated with the conditioned response (CR) developed in the IPN and PN during CS1-US training. Subsequent CS2-US training resulted in acquisition of CRs and learning-related neuronal activity in the IPN but substantially less little learning-related activity in the PN. Additional CS1/CS2 training increased CRs and learning-related activity in the IPN and PN during CS2-US trials. The findings suggest that cross-modal neuronal plasticity in the PN is driven by excitatory feedback from the IPN to the PN. Interacting plasticity mechanisms in the IPN and PN may underlie behavioral cross-modal transfer in eyeblink conditioning. PMID:21411647

Preparing insightful teaching and learning materials for a lesson does need the effort from the educators. Educators should make some research of suitable ways to improve their teaching and learning sessions. In this 21st century, technologies are widely used as tools for education. Even so, there are educators that willing to support and some who do not agree to change. The aim of this study is to develop an innovation teaching materials by applying web 2.0 tools. The intention is to broaden knowledge and in the same time getting response and feedback from people regarding the teaching and learning session materials produced with proper instruction. Action research was used to give a structured flow of this study. The outcome of this study was encouraging and the reflection of this study can help educators in improvising their teaching and learning sessions and materials using action research.

Short-term and long-term memory deficits in handedness learning in mice with absent corpus callosum and reduced hippocampal commissure.

The corpus callosum (CC) and hippocampal commissure (HC) are major interhemispheric connections whose role in brain function and behaviors is fascinating and contentious. Paw preference of laboratory mice is a genetically regulated, adaptive behavior, continuously shaped by training and learning. We studied variation with training in paw-preference in mice of the 9XCA/WahBid ('9XCA') recombinant inbred strain, selected for complete absence of the CC and severely reduced HC. We measured sequences of paw choices in 9XCA mice in two training sessions in unbiased test chambers, separated by one-week. We compared them with sequences of paw choices in model non-learner mice that have random unbiased paw choices and with those of C57BL/6JBid ('C57BL/6J') mice that have normal interhemispheric connections and learn a paw preference. Positive autocorrelation between successive paw choices during each session and change in paw-preference bias between sessions indicate that 9XCA mice have weak, but not null, learning skills. We tested the effect of the forebrain commissural defect on paw-preference learning with the independent BTBR T+ tf/J ('BTBR') mouse strain that has a genetically identical, non-complementing commissural trait. BTBR has weak short-term and long-term memory skills, identical to 9XCA. The results provide strong evidence that CC and HC contribute in memory function and formation of paw-preference biases.

Motor skill learning is one of the key components of motor function recovery after stroke, especially recovery driven by neurorehabilitation. Transcranial direct current stimulation can enhance neurorehabilitation and motor skill learning in stroke patients. However, the neural mechanisms underlying the retention of stimulation-enhanced motor skill learning involving a paretic upper limb have not been resolved. These neural substrates were explored by means of functional magnetic resonance imaging. Nineteen chronic hemiparetic stroke patients participated in a double-blind, cross-over randomized, sham-controlled experiment with two series. Each series consisted of two sessions: (i) an intervention session during which dual transcranial direct current stimulation or sham was applied during motor skill learning with the paretic upper limb; and (ii) an imaging session 1 week later, during which the patients performed the learned motor skill. The motor skill learning task, called the ‘circuit game’, involves a speed/accuracy trade-off and consists of moving a pointer controlled by a computer mouse along a complex circuit as quickly and accurately as possible. Relative to the sham series, dual transcranial direct current stimulation applied bilaterally over the primary motor cortex during motor skill learning with the paretic upper limb resulted in (i) enhanced online motor skill learning; (ii) enhanced 1-week retention; and (iii) superior transfer of performance improvement to an untrained task. The 1-week retention’s enhancement driven by the intervention was associated with a trend towards normalization of the brain activation pattern during performance of the learned motor skill relative to the sham series. A similar trend towards normalization relative to sham was observed during performance of a simple, untrained task without a speed/accuracy constraint, despite a lack of behavioural difference between the dual transcranial direct current stimulation and sham series. Finally, dual transcranial direct current stimulation applied during the first session enhanced continued learning with the paretic limb 1 week later, relative to the sham series. This lasting behavioural enhancement was associated with more efficient recruitment of the motor skill learning network, that is, focused activation on the motor-premotor areas in the damaged hemisphere, especially on the dorsal premotor cortex. Dual transcranial direct current stimulation applied during motor skill learning with a paretic upper limb resulted in prolonged shaping of brain activation, which supported behavioural enhancements in stroke patients.

2017-01-01

Knowledge and application of experimental design principles are essential components of scientific methodology, and experience with these skills is fundamental for participating in scientific research. However, undergraduates often enter the research laboratory with little training in designing and interpreting their own experiments. In the context of a research university laboratory, we designed a journal club training exercise to address this need. Students were instructed on methods for interpreting scientific literature using a screencast, a digital recording of a slide presentation narrated by an instructor. Students subsequently examined a series of research publications with a focus on the experimental designs and data interpretation in a two-session group discussion journal club format. We have found this approach to be an efficient and productive method for engaging students in learning about principles of experimental design and further preparing them for success in laboratory research.

Towards a robust BCI: error potentials and online learning.

PubMed

Buttfield, Anna; Ferrez, Pierre W; Millán, José del R

2006-06-01

Recent advances in the field of brain-computer interfaces (BCIs) have shown that BCIs have the potential to provide a powerful new channel of communication, completely independent of muscular and nervous systems. However, while there have been successful laboratory demonstrations, there are still issues that need to be addressed before BCIs can be used by nonexperts outside the laboratory. At IDIAP Research Institute, we have been investigating several areas that we believe will allow us to improve the robustness, flexibility, and reliability of BCIs. One area is recognition of cognitive error states, that is, identifying errors through the brain's reaction to mistakes. The production of these error potentials (ErrP) in reaction to an error made by the user is well established. We have extended this work by identifying a similar but distinct ErrP that is generated in response to an error made by the interface, (a misinterpretation of a command that the user has given). This ErrP can be satisfactorily identified in single trials and can be demonstrated to improve the theoretical performance of a BCI. A second area of research is online adaptation of the classifier. BCI signals change over time, both between sessions and within a single session, due to a number of factors. This means that a classifier trained on data from a previous session will probably not be optimal for a new session. In this paper, we present preliminary results from our investigations into supervised online learning that can be applied in the initial training phase. We also discuss the future direction of this research, including the combination of these two currently separate issues to create a potentially very powerful BCI.

Near-peer teaching is an educational format which utilizes tutors who are more advanced in a curriculum's content to supervise students' activities and to act as instructors in laboratory settings. This format is often used in anatomy laboratory courses. The goal of the present study is to describe the design and implementation of near-peer teaching in an anatomy course and to evaluate students' perceptions of the program. A total of 700 students were registered for this anatomy course which employed near-peer instructors. Of enrolled students, 558 (79.7%) agreed to participate in this study. In general, the practical section (e.g., the clinical hour, image-based anatomy session, and gross anatomy laboratory) of the course was viewed more favorably compared to the theory section (54.8%, n = 306), with dissection and prosection in the laboratory rated as the most valued experiences (34.9%, n = 195). Near-peer teaching is a viable option that satisfies the demands of modern curricula using small groups. This format stimulates learning within courses that have large numbers of students and low faculty-to-student ratios. Copyright © 2012 American Association of Anatomists.

The present study investigates how the temperament of the animal affects the influence of acute stress on the acquisition and reacquisition processes of a learning task. After temperament was assessed, horses were subjected to a stressor before or after the acquisition session of an instrumental task. Eight days later, horses were subjected to a reacquisition session without any stressor. Stress before acquisition tended to enhance the number of successes at the beginning of the acquisition session. Eight days later, during the reacquisition session, contrary to non-stressed animals, horses stressed after acquisition, and, to a lesser extent, horses stressed before acquisition, did not improve their performance between acquisition and reacquisition sessions. Temperament influenced learning performances in stressed horses only. Particularly, locomotor activity improved performances whereas fearfulness impaired them under stressful conditions. Results suggest that direct exposure to a stressor tended to increase acquisition performances, whereas a state of stress induced by the memory of a stressor, because it has been previously associated with the learning context, impaired reacquisition performances. The negative effect of a state of stress on reacquisition performances appeared to be stronger when exposure to the stressor occurred after rather than before the acquisition session. Temperament had an impact on both acquisition and reacquisition processes, but under stressful conditions only. These results suggest that stress is necessary to reveal the influence of temperament on cognitive performances. PMID:23626801

To assess use of the combined just-in-time teaching (JiTT) and peer instruction (PI) instructional strategy in a residency program's core curriculum. In 2010-2011, JiTT/PI was piloted in 31 core curriculum sessions taught by 22 faculty in the Northwestern University Feinberg School of Medicine's general surgery residency program. JiTT/PI required preliminary and categorical residents (n=31) to complete Web-based study questions before weekly specialty topic sessions. Responses were examined by faculty members "just in time" to tailor session content to residents' learning needs. In the sessions, residents answered multiple-choice questions (MCQs) using clickers and engaged in PI. Participants completed surveys assessing their perceptions of JiTT/PI. Videos were coded to assess resident engagement time in JiTT/PI sessions versus prior lecture-based sessions. Responses to topic session MCQs repeated in review sessions were evaluated to study retention. More than 70% of resident survey respondents indicated that JiTT/PI aided in the learning of key points. At least 90% of faculty survey respondents reported positive perceptions of aspects of the JiTT/PI strategy. Resident engagement time for JiTT/PI sessions was significantly greater than for prior lecture-based sessions (z=-2.4, P=.016). Significantly more review session MCQ responses were correct for residents who had attended corresponding JiTT/PI sessions than for residents who had not (chi-square=13.7; df=1; P<.001). JiTT/PI increased learner participation, learner retention, and the amount of learner-centered time. JiTT/PI represents an effective approach for meaningful and active learning in core curriculum sessions.

Effects of Learning on Performance When Computerized Dynamic Posturography Assessments Are Repeated

NASA Technical Reports Server (NTRS)

Taylor, Laura C.; Paloski, William H.; Wood, Scott J.

2008-01-01

Background: Computerized dynamic posturography is widely used to measure balance control performance. Clinically, performance is assessed by comparing individual data against standards obtained from a normative population. When performing repeated assessments to track performance changes, one must be concerned with the influence of learning effects. Subjects do not have the opportunity to practice before the first session, and often a second session is not performed prior to an experiment. Thus, the objective of this activity was to examine learning effects on balance control performance. We hypothesize that subjects will perform better on the second session when compared to the first, and that the difference will be greater for more difficult conditions. Methods: Data were collected from 204 subjects using the NeuroCom Equitest system during quiet stance with arms crossed at the chest on up to two sessions. All subjects performed standard sensory organization tests (SOTs) including 1) normal vision, fixed support; 2) absent vision, fixed support; 3) sway-referenced vision, fixed support; 4) normal vision, swayreferenced support; 5) absent vision, sway-referenced support; and 6) sway-referenced vision, sway-referenced support. 120 of these subjects performed modified sensory organization tests (mSOTs 2 and 5) which included static (20 back) and dynamic (20, 0.33Hz) head tilts. Median equilibrium scores (mEQ) were calculated from peak-to-peak anterior-posterior sway across trials. Data collected on the first session were then compared with the second to examine learning effect. Results: There were no differences in mEQ scores between the first and second sessions for SOTs 1, 2, and 4, while mEQ scores were higher for the second session when compared to the first for SOTs 3, 5, and 6 and for all mSOTs. Discussion: An additional familiarization session or practice trials prior to the first session may be necessary for more challenging SOT and mSOT conditions to minimize learning effect.

Children with severe motor impairments who cannot use direct selection are typically introduced to scanning as a means of accessing assistive technology. Unfortunately, it is difficult for young children to learn to scan because the design of current scanning techniques does not always make explicit the offer of items from the selection array; furthermore, it does not provide explicit feedback after activation of the switch to select the target item. In the current study, scanning was redesigned to reduce learning demands by making both the offer of items and the feedback upon selection more explicit through the use of animation realized through HTML and speech output with appropriate intonation. Twenty typically developing 2-year-olds without disabilities were randomly assigned to use either traditional scanning or enhanced scanning to select target items from an array of three items. The 2-year-olds did not learn to use traditional scanning across three sessions. Their performance in Session 3 did not differ from that in Session 1; they did not exceed chance levels of accuracy in either session (mean accuracy of 20% for Sessions 1 and 3). In contrast, the children in the enhanced scanning condition demonstrated improvements in accuracy across the three 10-20-min sessions (mean accuracies of 22 and 48% for Sessions 1 and 3, respectively). There were no reliable differences between the children's performances with the two scanning techniques for Session 1; however, by Session 3, the children were more than twice as accurate using the enhanced scanning technique compared to the traditional design. Results suggest that by redesigning scanning, we may be able to reduce some of the learning demands and thereby reduce some of the instructional time required for children to attain mastery. Clinical implications, limitations, and directions for future research and development are discussed.

Mixed-Effects Modeling of Neurofeedback Self-Regulation Performance: Moderators for Learning in Children with ADHD.

2018-01-01

Neurofeedback (NF) has gained increasing popularity as a training method for children and adults with attention deficit hyperactivity disorder (ADHD). However, it is unclear to what extent children learn to regulate their brain activity and in what way NF learning may be affected by subject- and treatment-related factors. In total, 48 subjects with ADHD (age 8.5-16.5 years; 16 subjects on methylphenidate (MPH)) underwent 15 double training sessions of NF in either a clinical or a school setting. Four mixed-effects models were employed to analyze learning: training within-sessions, across-sessions, with continuous feedback, and with transfer in which performance feedback is delayed. Age and MPH affected the NF performance in all models. Cross-session learning in the feedback condition was mainly moderated by age and MPH, whereas NF learning in the transfer condition was mainly boosted by MPH. Apart from IQ and task types, other subject-related or treatment-related effects were unrelated to NF learning. This first study analyzing moderators of NF learning in ADHD with a mixed-effects modeling approach shows that NF performance is moderated differentially by effects of age and MPH depending on the training task and time window. Future studies may benefit from using this approach to analyze NF learning and NF specificity. The trial name Neurofeedback and Computerized Cognitive Training in Different Settings for Children and Adolescents With ADHD is registered with NCT02358941.

Development of the electronic health records for nursing education (EHRNE) software program.

PubMed

Kowitlawakul, Yanika; Wang, Ling; Chan, Sally Wai-Chi

2013-12-01

This paper outlines preliminary research of an innovative software program that enables the use of an electronic health record in a nursing education curriculum. The software application program is called EHRNE, which stands for Electronic Heath Record for Nursing Education. The aim of EHRNE is to enhance student's learning of health informatics when they are working in the simulation laboratory. Integrating EHRNE into the nursing curriculum exposes students to electronic health records before they go into the workplace. A qualitative study was conducted using focus group interviews of nine nursing students. Nursing students' perceptions of using the EHRNE application were explored. The interviews were audio-taped and transcribed verbatim. The data was analyzed following the Colaizzi (1978) guideline. Four main categories that related to the EHRNE application were identified from the interviews: functionality, data management, timing and complexity, and accessibility. The analysis of the data revealed advantages and limitations of using EHRNE in the classroom setting. Integrating the EHRNE program into the curriculum will promote students' awareness of electronic documentation and enhance students' learning in the simulation laboratory. Preliminary findings suggested that before integrating the EHRNE program into the nursing curriculum, educational sessions for both students and faculty outlining the software's purpose, advantages, and limitations were needed. Following the educational sessions, further investigation of students' perceptions and learning using the EHRNE program is recommended. Copyright © 2012 Elsevier Ltd. All rights reserved.

The time course and outcome of perceptual learning can be affected by the length and distribution of practice, but the training regimen parameters that govern these effects have received little systematic study in the auditory domain. We asked whether there was a minimum requirement on the number of trials within a training session for learning to occur, whether there was a maximum limit beyond which additional trials became ineffective, and whether multiple training sessions provided benefit over a single session. We investigated the efficacy of different regimens that varied in the distribution of practice across training sessions and in the overall amount of practice received on a frequency discrimination task. While learning was relatively robust to variations in regimen, the group with the shortest training sessions (∼8 min) had significantly faster learning in early stages of training than groups with longer sessions. In later stages, the group with the longest training sessions (>1 hr) showed slower learning than the other groups, suggesting overtraining. Between-session improvements were inversely correlated with performance; they were largest at the start of training and reduced as training progressed. In a second experiment we found no additional longer-term improvement in performance, retention, or transfer of learning for a group that trained over 4 sessions (∼4 hr in total) relative to a group that trained for a single session (∼1 hr). However, the mechanisms of learning differed; the single-session group continued to improve in the days following cessation of training, whereas the multi-session group showed no further improvement once training had ceased. Shorter training sessions were advantageous because they allowed for more latent, between-session and post-training learning to emerge. These findings suggest that efficient regimens should use short training sessions, and optimized spacing between sessions.

Lower back pain is commonly associated with golfers. The study aimed: to determine whether thoracic- and lumbar-erector-spinae muscle display signs of muscular fatigue after completing a golf practice session, and to examine the effect of the completed practice session on club head speed, ball speed and absolute carry distance performance variables. Fourteen right-handed male golfers participated in the laboratory-based-study. Surface electromyography (EMG) data was collected from the lead and trail sides of the thoracic- and lumbar-erector-spinae muscle. Normalized root mean squared (RMS) EMG activation levels and performance variables for the golf swings were compared before and after the session. Fatigue was assessed using median frequency (MDF) and RMS during the maximum voluntary contraction (MVC) performed before and after the session. No significant differences were observed in RMS thoracic- and lumbar-erector-spinae muscle activation levels during the five phases of the golf swing and performance variables before and after the session (p > .05). Significant changes were displayed in MDF and RMS when comparing the MVC performed before and after the session (p < .05). Fatigue was evident in the trail side of the erector-spinae muscle after the session.

The potential remote sensing user community is enormous, and the teaching and training tasks are even larger; however, some underlying principles may be synthesized and applied at all levels from elementary school children to sophisticated and knowledgeable adults. The basic rules applying to each of the six major elements of any training course and the underlying principle involved in each rule are summarized. The six identified major elements are: (1) field sites for problems and practice; (2) lectures and inside study; (3) learning materials and resources (the kit); (4) the field experience; (5) laboratory sessions; and (6) testing and evaluation.

Laboratory activity is an important part of chemistry learning, but cookbook instructions is still commonly used. However, the activity with that way do not improve students thinking skill, especially students creativity. This study aims to improve high school students creativity through inquiry-based laboratory on drugs analysis activity. Acid-base titration is used to be method for drugs analysis involving a color changing indicator. The following tools were used to assess the activity achievement: creative thinking test on acid base titration, creative attitude and action observation sheets, questionnaire of inquiry-based lab activities, and interviews. The results showed that the inquiry-based laboratory activity improving students creative thinking, creative attitude and creative action. The students reacted positively to this teaching strategy as demonstrated by results from questionnaire responses and interviews. This result is expected to help teachers to overcome the shortcomings in other laboratory learning.

The use of virtual patients (VPs), due to their high complexity and/or inappropriate sequencing with other instructional methods, might cause a high cognitive load, which hampers learning. To investigate the efficiency of instructional methods that involved three different applications of VPs combined with lectures. From two consecutive batches, 171 out of 183 students have participated in lecture and VPs sessions. One group received a lecture session followed by a collaborative VPs learning activity (collaborative deductive). The other two groups received a lecture session and an independent VP learning activity, which either followed the lecture session (independent deductive) or preceded it (independent inductive). All groups were administrated written knowledge acquisition and retention tests as well as transfer tests using two new VPs. All participants completed a cognitive load questionnaire, which measured intrinsic, extraneous and germane load. Mixed effect analysis of cognitive load and efficiency using the R statistical program was performed. The highest intrinsic and extraneous load was found in the independent inductive group, while the lowest intrinsic and extraneous load was seen in the collaborative deductive group. Furthermore, comparisons showed a significantly higher efficiency, that is, higher performance in combination with lower cognitive load, for the collaborative deductive group than for the other two groups. Collaborative use of VPs after a lecture is the most efficient instructional method, of those tested, as it leads to better learning and transfer combined with lower cognitive load, when compared with independent use of VPs, either before or after the lecture.

Participating in a Community of Learners enhances resident perceptions of learning in an e-mentoring program: proof of concept

PubMed Central

2011-01-01

Background Community learning and e-mentoring, learning methods used in higher education, are not used to any extent in residency education. Yet both have the potential to enhance resident learning and, in the case of community learning, introduce residents to basic lifelong learning skills. We set out to determine whether residents participating in an Internet based e-mentoring program would, with appropriate facilitation, form a community of learners (CoL) and hold regular community meetings. We also determined resident and faculty perceptions of CoL and Internet sessions as effective learning experiences. Methods A six-month e-mentoring pilot was offered to 10 Radiology residents in the Aga Khan University Postgraduate Medical Education Program in Nairobi, Kenya (AKUHN) with a Professor of Radiology, located at University of Virginia, USA, acting as the e-mentor. Monthly Internet case-based teaching sessions were facilitated by the e-mentor. In addition, residents were coached by a community facilitator to form CoL and collectively work through clinical cases at weekly face-to-face CoL sessions. Event logs described observed resident activity at CoL sessions; exit survey and interviews were used to elicit perceptions of CoL and Internet sessions as effective learning experiences. Results Resident adoption of CoL behaviors was observed, including self-regulation, peer mentoring and collaborative problem solving. Analysis revealed high resident enthusiasm and value for CoL. Surveys and interviews indicated high levels of acceptance of Internet learning experiences, although there was room for improvement in audio-visual transmission technologies. Faculty indicated there was a need for a larger multi-specialty study. Conclusions The pilot demonstrated resident acceptance of community building and collaborative learning as valued learning experiences, addressing one barrier to its formal adoption in residency education curricula. It also highlighted the potential of e-mentoring as a means of expanding faculty and teaching materials in residency programs in developing countries. PMID:21266070

Feedback in medical teaching is an important part of medical education, it encourages and enhances the learners' knowledge, skills and professional performance at various stages of their schooling. A constructive feedback enhances the awareness of strength and areas for improvement. An adequate, meaningful and fruitful feedback needs motivation, emphasis, objectivity, expertise, and active participation in the session. Before giving feedback, the instructor should be well prepared and must have practice on the task. The instructor should utilize all means such as good oral presentation, eye contact, visual cues, utilize body language to actively involve the learners in a session, all these activities enhance the knowledge, skill and attitude of the learners. The aim of this commentary is to highlight the basic issues in giving an appropriate feedback in medical teaching with special emphasis on a lung function laboratory / Spirometry.

The Romanian Association of Medical Laboratories (RAML) conferences have acquired a reputation for standing out as the most prominent and efficient meetings in the national community of laboratory medicine, being a landmark of the development in this field in Romania and an active affiliation to international forums. This year, the conference setting was Piatra Neamt, in the northeast part of Romania, which produced a friendly and stimulating professional environment. As in previous years, leading experts in the fields of laboratory medicine attended the event. This year, we enjoyed the opportunity to have such distinguished guests as the members of the executive board of International Federation of Clinical Chemistry and Laboratory Medicine (IFCC); Graham Beastall, IFCC President; Päivi Hannele Laitinen, IFCC secretary; and Grazyna Sypniewska, IFCC Communication and Publication Division, and editor of the electronic journal of the IFCC. As usual, the conference program included all aspects of clinical laboratory activity, with a special focus on technology development, instrumentation and laboratory management. Fully aware of the fact that the complexity and depth of laboratory practice have undergone an impressive and rapid evolution, the specific goals of the event were to increase knowledge in the fundamentals of new molecular investigation, areas which show the tendency to become routine in our daily activity. In addition, laboratory management and the place of medical laboratories in the process of translational medicine were subjects of focus. The 6th Conference of the Romanian Association of Medical Laboratories was held from Wednesday 1st to Saturday 4th of June 2011. A total of 273 participants from all local branches of the Association attended. The scientific program included seven plenary sessions where 22 lectures and 18 short communications were delivered, and three poster sessions with 44 poster presentations. Session topics covered issues of laboratory diagnostics in hematology, biochemistry, immunology, oncology, microbiology and metabolic diseases. A prominent consideration was given to value added to laboratory medicine in the frame of managed care and quality management. The Conference was accompanied by a laboratory equipment and reagents exhibition with the participation of nine companies, also sponsors of the conference. Three workshops pointed out the presence of the most well known of them: Abbott, Roche and Nobis.

Applications of "Integrated Data Viewer'' (IDV) in the classroom

NASA Astrophysics Data System (ADS)

Nogueira, R.; Cutrim, E. M.

2006-06-01

Conventionally, weather products utilized in synoptic meteorology reduce phenomena occurring in four dimensions to a 2-dimensional form. This constitutes a road-block for non-atmospheric-science majors who need to take meteorology as a non-mathematical and complementary course to their major programs. This research examines the use of Integrated Data Viewer-IDV as a teaching tool, as it allows a 4-dimensional representation of weather products. IDV was tested in the teaching of synoptic meteorology, weather analysis, and weather map interpretation to non-science students in the laboratory sessions of an introductory meteorology class at Western Michigan University. Comparison of student exam scores according to the laboratory teaching techniques, i.e., traditional lab manual and IDV was performed for short- and long-term learning. Results of the statistical analysis show that the Fall 2004 students in the IDV-based lab session retained learning. However, in the Spring 2005 the exam scores did not reflect retention in learning when compared with IDV-based and MANUAL-based lab scores (short term learning, i.e., exam taken one week after the lab exercise). Testing the long-term learning, seven weeks between the two exams in the Spring 2005, show no statistically significant difference between IDV-based group scores and MANUAL-based group scores. However, the IDV group obtained exam score average slightly higher than the MANUAL group. Statistical testing of the principal hypothesis in this study, leads to the conclusion that the IDV-based method did not prove to be a better teaching tool than the traditional paper-based method. Future studies could potentially find significant differences in the effectiveness of both manual and IDV methods if the conditions had been more controlled. That is, students in the control group should not be exposed to the weather analysis using IDV during lecture.

Although blended learning has the potential to enhance the student experience, both in terms of engagement and flexibility, it can be difficult to effectively restructure existing courses. To achieve these goals for an introductory Pathology course, offered to more than 250 undergraduate students at UNSW Sydney, we devised a novel approach. For each topic presented over 2-3 weeks, a single face-to-face overview lecture was retained. The remaining content that had previously been delivered as conventional lectures was converted into short (12-18 min) online modules. These were based on lecture slides with added animations/highlights, plus narration using edited excerpts of previous lecture recordings. The modules also incorporated interactive questions and review quizzes with feedback which used various question types. Modules were developed in PowerPoint and iSpring and uploaded to Moodle as SCORM packages. Each topic concluded with an interactive large-group session focussing on integration of the content, with in-class questions to which students could respond via the Echo360 Active Learning Platform (ALP). Overall, more than 50% of face-to-face lecture time was replaced by online modules and interactive large-group sessions. Quantitative evaluation data included usage statistics from 264 students and feedback via online survey responses from 41 students. Qualitative evaluation data consisted of reflective commentaries from 160 student ePortfolios, which were analysed to identify factors affecting learning benefits and user acceptability. All of the modules were completed by 74% of students and on average, 83.1% of students eventually passed the optional review quizzes. Notably, 88.4% of students responded to in-class questions during the integration and feedback sessions via the ALP. Student reflections emphasised that the modules promoted understanding, which was reinforced through active learning. The modules were described as enjoyable, motivating and were appreciated for their flexibility, which enabled students to work at their own pace. In transforming this introductory Pathology course, we have demonstrated a model for the use of blended learning in large group teaching sessions, which achieved high levels of completion, satisfaction and value for learning.

Electrode replacement does not affect classification accuracy in dual-session use of a passive brain-computer interface for assessing cognitive workload

Estepp, Justin R.; Christensen, James C.

2015-01-01

The passive brain-computer interface (pBCI) framework has been shown to be a very promising construct for assessing cognitive and affective state in both individuals and teams. There is a growing body of work that focuses on solving the challenges of transitioning pBCI systems from the research laboratory environment to practical, everyday use. An interesting issue is what impact methodological variability may have on the ability to reliably identify (neuro)physiological patterns that are useful for state assessment. This work aimed at quantifying the effects of methodological variability in a pBCI design for detecting changes in cognitive workload. Specific focus was directed toward the effects of replacing electrodes over dual sessions (thus inducing changes in placement, electromechanical properties, and/or impedance between the electrode and skin surface) on the accuracy of several machine learning approaches in a binary classification problem. In investigating these methodological variables, it was determined that the removal and replacement of the electrode suite between sessions does not impact the accuracy of a number of learning approaches when trained on one session and tested on a second. This finding was confirmed by comparing to a control group for which the electrode suite was not replaced between sessions. This result suggests that sensors (both neurological and peripheral) may be removed and replaced over the course of many interactions with a pBCI system without affecting its performance. Future work on multi-session and multi-day pBCI system use should seek to replicate this (lack of) effect between sessions in other tasks, temporal time courses, and data analytic approaches while also focusing on non-stationarity and variable classification performance due to intrinsic factors.

Posttraining transcranial magnetic stimulation of striate cortex disrupts consolidation early in visual skill learning.

Practice-induced improvements in skilled performance reflect "offline " consolidation processes extending beyond daily training sessions. According to visual learning theories, an early, fast learning phase driven by high-level areas is followed by a late, asymptotic learning phase driven by low-level, retinotopic areas when higher resolution is required. Thus, low-level areas would not contribute to learning and offline consolidation until late learning. Recent studies have challenged this notion, demonstrating modified responses to trained stimuli in primary visual cortex (V1) and offline activity after very limited training. However, the behavioral relevance of modified V1 activity for offline consolidation of visual skill memory in V1 after early training sessions remains unclear. Here, we used neuronavigated transcranial magnetic stimulation (TMS) directed to a trained retinotopic V1 location to test for behaviorally relevant consolidation in human low-level visual cortex. Applying TMS to the trained V1 location within 45 min of the first or second training session strongly interfered with learning, as measured by impaired performance the next day. The interference was conditional on task context and occurred only when training in the location targeted by TMS was followed by training in a second location before TMS. In this condition, high-level areas may become coupled to the second location and uncoupled from the previously trained low-level representation, thereby rendering consolidation vulnerable to interference. Our data show that, during the earliest phases of skill learning in the lowest-level visual areas, a behaviorally relevant form of consolidation exists of which the robustness is controlled by high-level, contextual factors.

Motor skill learning is one of the key components of motor function recovery after stroke, especially recovery driven by neurorehabilitation. Transcranial direct current stimulation can enhance neurorehabilitation and motor skill learning in stroke patients. However, the neural mechanisms underlying the retention of stimulation-enhanced motor skill learning involving a paretic upper limb have not been resolved. These neural substrates were explored by means of functional magnetic resonance imaging. Nineteen chronic hemiparetic stroke patients participated in a double-blind, cross-over randomized, sham-controlled experiment with two series. Each series consisted of two sessions: (i) an intervention session during which dual transcranial direct current stimulation or sham was applied during motor skill learning with the paretic upper limb; and (ii) an imaging session 1 week later, during which the patients performed the learned motor skill. The motor skill learning task, called the 'circuit game', involves a speed/accuracy trade-off and consists of moving a pointer controlled by a computer mouse along a complex circuit as quickly and accurately as possible. Relative to the sham series, dual transcranial direct current stimulation applied bilaterally over the primary motor cortex during motor skill learning with the paretic upper limb resulted in (i) enhanced online motor skill learning; (ii) enhanced 1-week retention; and (iii) superior transfer of performance improvement to an untrained task. The 1-week retention's enhancement driven by the intervention was associated with a trend towards normalization of the brain activation pattern during performance of the learned motor skill relative to the sham series. A similar trend towards normalization relative to sham was observed during performance of a simple, untrained task without a speed/accuracy constraint, despite a lack of behavioural difference between the dual transcranial direct current stimulation and sham series. Finally, dual transcranial direct current stimulation applied during the first session enhanced continued learning with the paretic limb 1 week later, relative to the sham series. This lasting behavioural enhancement was associated with more efficient recruitment of the motor skill learning network, that is, focused activation on the motor-premotor areas in the damaged hemisphere, especially on the dorsal premotor cortex. Dual transcranial direct current stimulation applied during motor skill learning with a paretic upper limb resulted in prolonged shaping of brain activation, which supported behavioural enhancements in stroke patients. © The Author (2014).

To enhance students' knowledge of and critical-thinking skills in the management of acutely ill patients using online independent learning partnered with high-fidelity patient simulation sessions. Students enrolled in the Acute Care Simulation watched 10 weekly Web-based video presentations on various critical care and advanced cardiovascular pharmacotherapy topics. After completing each online module, all students participated in groups in patient-care simulation exercises in which they prepared a pharmacotherapeutic plan for the patient, recommended this plan to the patient's physician, and completed a debriefing session with the facilitator. Students completed a pretest and posttest before and after each simulation exercise, as well as midterm and final evaluations and a satisfaction survey. Pharmacy students significantly improved their scores on 9 of the 10 tests (p ≤ 0.05). Students' performance on the final evaluation improved compared with performance on the midterm evaluation. Overall, students were satisfied with the unique dual approach to learning and enjoyed the realistic patient-care environment that the simulation laboratory provided. Participation in an elective course that combined self-directed Web-based learning and hands-on patient simulation exercises increased pharmacy students' knowledge and critical-thinking skills in acute care.

Learning to teach inquiry with ICT

2018-01-01

Research has shown that the objectives for laboratory teaching—just as with other teaching methods—are often not achieved and that many laboratory sessions are ineffective and yet expensive in terms of pupil and teacher time, and facilities. There are several reasons for this, but one reason is that instructions for many lab activities are too prescriptive and leave too little room for thinking and creativity of pupils. Even though this problem had been pointed out already in the early 1980s, it has persisted to this day. Additionally, ICT tools such as data logging, video measurement, and modelling have been available to secondary schools for decades. These tools provide unique opportunities for authentic investigations at the secondary school level. However, even friendly software might require considerable instruction and reinforce a prescriptive approach. Therefore, we developed a course for pre-service and in-service teachers to learn to apply ICT tools in a minds-on and inquiry way. The short course (1 ECTS  =  28 study hours) described in this article was tried out in three different countries (the Netherlands, Slovakia, Vietnam) and improved through different cycles of iterative development. Its pedagogical principles were validated through research and may be applicable and useful in other areas of teacher education and professional development.

The special session aims at discussing an integrated approach of the different efforts to increase and promote the teaching and learning of astronomy in the world, with emphasis on developing countries. To this end, attention will be given to research on education, specifically in the field of physics, to best practices of the use of astronomy in educational systems (specifically in developing countries), and to innovative learning initiatives other than formal education. The Special Session aims also at creating a universal perspective wherein modern (post-Copernican) astronomy will presented as an intellectual cumulus. The objective of the session is to disseminate best practices in teaching and learning activities of astronomy and to give an opportunity to learn about initiatives in different cultural and socio-economic settings. The special session also wants to give food-for-thought and proposals for reflection for an integrative approach, and for optimization processes, to enhance the interest in astronomy and its role as a trigger towards science education in the educational systems, with emphasis on the developing countries. The outcome should be a sensitization of teachers and students alike to the concept of a universal history of astronomy and creation of some reliable source material which can be used as a teaching aid in a culture-specific context. The outcome could be a set of recommendations for future integrated actions, and eventually recommendations on new initiatives, framed into the new decadal policy plan.

The neural bases of the learning and generalization of morphological inflection.

Affixal inflectional morphology has been intensively examined as a model of productive aspects of language. Nevertheless, little is known about the neurocognition of the learning and generalization of affixal inflection, or the influence of certain factors that may affect these processes. In an event-related fMRI study, we examined the neurocognition of the learning and generalization of plural inflections in an artificial language, as well as the influence of both affix type frequency (the proportion of words receiving a given affix) and affix predictability (based on phonological cues in the stem). Adult participants were trained in three sessions, and were scanned after the first and last sessions while inflecting trained and untrained words. Untrained words yielded more activation than trained words in medial frontal (including pre-SMA) and left inferior frontal cortices, which have previously shown activation in compositional grammatical processing. A reliance on phonological cues for untrained word inflection correlated positively with pre-SMA activation, but negatively with activation in the pars triangularis. Thus, pre-SMA may be involved in phonological cue-based composition, while the pars triangularis underlies alternative processes. Inflecting trained items yielded activation in the caudate head bilaterally, only in the first session, consistent with a role for procedural memory in learning grammatical regularities. The medial frontal and left inferior regions activated by untrained items were also activated by trained items, but more weakly than untrained items, with weakest activation for trained-items taking the high-frequency affix. This suggests less involvement of compositional processes for inflecting trained than untrained items, and least of all for trained inflected forms with high-frequency affixes, consistent with the storage of such forms (e.g., in declarative memory). Overall, the findings further elucidate the neural bases of the learning and generalization of affixal morphology, and the roles of affix type frequency and affix phonological predictability in these processes. Moreover, the results support and further specify the declarative/procedural model, in particular in adult language learning. Copyright © 2016 Elsevier Ltd. All rights reserved.

A spatial paradigm, the allothetic place avoidance alternation task, for testing visuospatial working memory and skill learning in rats.

PubMed

Dockery, Colleen A; Wesierska, Malgorzata J

2010-08-30

We present a paradigm for assessing visuospatial working memory and skill learning in a rodent model, based on the place avoidance test. In our allothetic place avoidance alternation task (APAAT) the paradigm is comprised of minimal training sessions, tests various aspects of learning and memory and provides a rich set of parameters. A single working memory session consists of four conditions: habituation (no shock), two place avoidance training intervals (shock activated) and a retrieval test (shock inactivated). The location of the shock sector is alternated for each training day which initially requires extinction of previous representations and further working memory to achieve effective place avoidance across sessions. Visuospatial skill memory was evaluated by the shock/entrance ratio by tracking locomotor activity which is essential to execute a place avoidance strategy. For each day rats learned to avoid a new place with shock, as shown by a decreased number of entrances, and an increased time to the first entrance and maximum avoidance time. Skill learning improved according to the decreased number of shocks per entrance across conditions. These results indicate that complex cognitive functions are captured by this behavioral method. This APAAT paradigm expands and complements existing tools for studying hippocampal-prefrontal dependent functions to support development of treatment interventions. Copyright (c) 2010 Elsevier B.V.

Pituitary adenylate cyclase-activating polypeptide (PACAP) and its receptor subtype 1 (PAC1) have been suggested to play a role in the modulation of learning and memory. However, behavioral evidence for altered mnemonic function due to altered PAC1 activity is missing. Therefore, the role of PAC1 in learning and memory was studied in mouse mutants lacking this receptor (PAC1 knock-out mice), tested in water maze two-choice spatial discrimination, one-trial contextual and cued fear conditioning, and multiple-session contextual discrimination. Water maze spatial discrimination was unaffected in PAC1 mutants, while a mild deficit was observed in multiple session contextual discrimination in PAC1 knock-out mice. Furthermore, PAC1 knock-out mice were able to learn the association between context and shock in one-trial contextual conditioning, but showed faster return to baseline than wild-type mice. Thus, the effects of PAC1 knock-out on modulating performance in these tasks were subtle and suggest that PAC1 only plays a limited role in learning and memory.

The supplemental instruction program: Student perceptions of the learning environment and impact on student academic achievement in college science at California State University, San Marcos

NASA Astrophysics Data System (ADS)

Hizer, Suzanne Elizabeth

Higher education in science has been criticized and calls to increase student learning and persistence to degree has been recognized as a national problem by the Department of Education, the National Science Foundation, the National Research Council, and the National Academy of Sciences. One mode of academic assistance that may directly address this issue is the implementation of Supplemental Instruction (SI) in science courses. SI is a specific model of academic assistance designed to help students in historically difficult science classes master course content, thus increasing their academic achievement and retention. This study assessed the SI program at California State University, San Marcos, in supported science courses. Specifically, academic achievement based on final course grades were compared between SI participating and nonparticipating students, multiple affective factors were measured at the beginning and end of the semester, and students' perceptions of the classroom and SI session learning environments recorded. Overall, students who attended five or more SI sessions achieved higher final course grades. Students who chose to participate in SI had higher initial levels of responsibility and anxiety. Additionally, SI participants experienced a reduction in anxiety over the semester whereas nonparticipants experienced an increase in anxiety from beginning to the end of the semester. The learning environment of SI embodies higher levels of constructivist principles of active learning such as cooperation, cohesiveness, innovation, and personalization---with one exception for the physics course, which is a based on problem-based learning. Structural equation modeling of variables indicates that high self-efficacy at the end of the semester is directly related to high final course grades; this is mediated by cohesion in the classroom and the cooperation evidenced in SI sessions. These findings are elaborated by student descriptions of what happened in SI sessions and discussed given the theoretical frameworks of Bandura's concept of self-efficacy and learning environment activities that embody constructivist principles.

Students' perceptions of their learning environment influence the quality of outcomes they achieve. Learning dental operative techniques in a simulated clinic environment is characterised by reciprocal interactions between skills training, staff- and student-related factors. However, few studies have examined how students perceive their operative learning environments and whether there is a relationship between their perceptions and subsequent performance. Therefore, this study aimed to clarify which learning activities and interactions students perceived as supporting their operative skills learning and to examine relationships with their outcomes. Longitudinal data about examples of operative laboratory sessions that were perceived as effective or ineffective for learning were collected twice a semester, using written critical incidents and interviews. Emergent themes from these data were identified using thematic analysis. Associations between perceptions of learning effectiveness and performance were analysed using chi-square tests. Students indicated that an effective learning environment involved interactions with tutors and peers. This included tutors arranging group discussions to clarify processes and outcomes, providing demonstrations and constructive feedback. Feedback focused on mistakes, and not improvement, was reported as being ineffective for learning. However, there was no significant association between students' perceptions of the effectiveness of their learning experiences and subsequent performance. It was clear that learning in an operative technique setting involved various factors related not only to social interactions and observational aspects of learning but also to cognitive, motivational and affective processes. Consistent with studies that have demonstrated complex interactions between students, their learning environment and outcomes, other factors need investigation. © 2014 John Wiley & Sons A/S.

2009-04-01

Perception of floor-projected moving geometric shapes was examined in the context of the Situated Multimedia Arts Learning Laboratory (SMALLab), an immersive, mixed-reality learning environment. As predicted, the projected destinations of shapes which retreated in depth (proximal origin) were judged significantly less accurately than those that approached (distal origin). Participants maintained similar magnitudes of error throughout the session, and no effect of practice was observed. Shape perception in an immersive multimedia environment is comparable to the real world. One may conclude that systematic exploration of basic psychological phenomena in novel mediated environments is integral to an understanding of human behavior in novel human-computer interaction architectures.

Learn why zero gravity is a misnomer and learn how to demonstrate microgravity to students and the general public. In this session, a short theory segment will explain and reinforce these concepts so that you may explain to others. Session participants will also see simple equipment that demonstrates microgravity during the session and can just as well be done in the classroom or museum exhibit hall. The hands-on demonstration devices range from a leaky water bottle to an electronic drop tower with an on-board camera. The session will also include demonstration techniques for Physics, Forces & Motion, and orbits. This material is useful for middle school forces and motions instruction, high school physics instruction, public demonstrations at conferences & school open houses, travelling museum exhibits, fixed museum exhibits, and independent student projects or experiments. These activities also connect the terrestrial demonstration with planetary & moon motion, comet trajectory, and more.

Movie screening and activities have been used during the last two semesters (spring and summer 2015) to strengthen the learning of communication skills, empathy, professionalism, and greater understanding of the process and death and dying at the Xavier University School of Medicine. The present manuscript describes the movie screening and activities. Student feedback regarding the sessions is also mentioned. The activity was conducted among basic science undergraduate medical students and student feedback was obtained. A cross-sectional study design was used. Feedback was obtained towards the end of June 2015 using a questionnaire designed by the authors. Participants were asked to rate their degree of agreement with the set of statements and provide an overall rating for the sessions. No demographic information was collected. Cronbach's alpha was calculated as a measure of internal consistency. The normality of distribution of the scores of individual statements and of the overall rating was determined using one sample Kolmogorov-Smirnov test. The average scores were calculated. Free text comments were tabulated. Forty-nine of the 63 students (77.8%) participated in the study. Cronbach's alpha was 0.868 indicating a high level of internal consistency. The median scores indicating the degree of agreement with most statements ranged from 3 to 5. The mean participant rating of the sessions was 7.10 (maximum possible score 10). A few participants provided free text comments regarding the sessions. Student feedback about the session was positive. Impact of the session on humanistic issues, professionalism and death and dying should be studied in future.

The superimposed-burst (SIB) technique is commonly used to quantify central activation failure after knee-joint injury, but its reliability has not been established in pathologic cohorts. To assess within-session and between-sessions reliability of the SIB technique in patients with patellofemoral pain. Descriptive laboratory study. University laboratory. A total of 10 patients with self-reported patellofemoral pain (1 man, 9 women; age = 24.1 ± 3.8 years, height = 167.8 ± 15.2 cm, mass = 71.6 ± 17.5 kg) and 10 healthy control participants (3 men, 7 women; age = 27.4 ± 5.0 years, height = 173.5 ± 9.9 cm, mass = 78.2 ± 16.5 kg) volunteered. Participants were assessed at 6 intervals spanning 21 days. Intraclass correlation coefficients (ICCs [3,3]) were used to assess reliability. Quadriceps central activation ratio, knee-extension maximal voluntary isometric contraction force, and SIB force. The quadriceps central activation ratio was highly reliable within session (ICC [3,3] = 0.97) and between sessions through day 21 (ICC [3,3] = 0.90-0.95). Acceptable reliability of knee extension (ICC [3,3] = 0.75-0.91) and SIB force (ICC [3,3] = 0.77-0.89) was observed through day 21. The SIB technique was reliable for clinical research up to 21 days in patients with patellofemoral pain.

Characterization of medical students recall of factual knowledge using learning objects and repeated testing in a novel e-learning system.

PubMed

2015-01-24

Spaced-repetition and test-enhanced learning are two methodologies that boost knowledge retention. ALERT STUDENT is a platform that allows creation and distribution of Learning Objects named flashcards, and provides insight into student judgments-of-learning through a metric called 'recall accuracy'. This study aims to understand how the spaced-repetition and test-enhanced learning features provided by the platform affect recall accuracy, and to characterize the effect that students, flashcards and repetitions exert on this measurement. Three spaced laboratory sessions (s0, s1 and s2), were conducted with n=96 medical students. The intervention employed a study task, and a quiz task that consisted in mentally answering open-ended questions about each flashcard and grading recall accuracy. Students were randomized into study-quiz and quiz groups. On s0 both groups performed the quiz task. On s1 and s2, the study-quiz group performed the study task followed by the quiz task, whereas the quiz group only performed the quiz task. We measured differences in recall accuracy between groups/sessions, its variance components, and the G-coefficients for the flashcard component. At s0 there were no differences in recall accuracy between groups. The experiment group achieved a significant increase in recall accuracy that was superior to the quiz group in s1 and s2. In the study-quiz group, increases in recall accuracy were mainly due to the session, followed by flashcard factors and student factors. In the quiz group, increases in recall accuracy were mainly accounted by flashcard factors, followed by student and session factors. The flashcard G-coefficient indicated an agreement on recall accuracy of 91% in the quiz group, and of 47% in the study-quiz group. Recall accuracy is an easily collectible measurement that increases the educational value of Learning Objects and open-ended questions. This metric seems to vary in a way consistent with knowledge retention, but further investigation is necessary to ascertain the nature of such relationship. Recall accuracy has educational implications to students and educators, and may contribute to deliver tailored learning experiences, assess the effectiveness of instruction, and facilitate research comparing blended-learning interventions.

Instruction and assessment strategies of undergraduate introductory biomechanics instructors have yet to be comprehensively examined. The purpose of this study was to identify the current instruction and assessment practices of North American undergraduate introductory biomechanics instructors and equipment needed for effective instruction in lecture and laboratory sessions. One hundred and sixty-five respondents (age: 42.5 +/- 10.3 years) who currently teach or have taught an introductory biomechanics course in North America were recruited by electronic mail. Subjects completed a web-based survey, consisting of 60 open- and closed-ended questions. Pearson's correlation coefficients were used to assess relationships between instructor's familiarity with either the Biomechanics Concept Inventory or the NASPE Guidelines for Undergraduate Biomechanics, and instructor and course characteristics (number of years teaching, age, faculty rank, number of quizzes given, etc.) A number of variables were significantly (p < 0.05) correlated. Answers to open-ended questions were processed using content analysis, with results categorized in content areas including: instructor and course characteristics; lecture instruction; assessment and equipment; laboratory instruction; assessment and equipment; and instructor's perspectives. Many active learning strategies for lecture and laboratory instruction were identified by faculty. Limited student preparation and limited resources were noted as the instructor's most common challenges.

The implementation of problem-based learning started in 1969 and has spread since then throughout different parts of the world with variations in its implementation. In spite of its growth and advantages, there is continuing debate about its effectiveness over the conventional teaching learning methods. In the School of Dental Sciences (SDS), Universiti Sains Malaysia (USM), the Doctor of Dental Sciences (DDS) program follows a 5-year integrated curriculum. Basically the curriculum is problem-based and community oriented. This study was to explore the perception of DDS students about PBL sessions. This questionnaires-based cross sectional descriptive study were carried out on all the 110 students of the SDS who completed their second year of the course and participated in PBL sessions. Ninety five (86%) students responded to the questionnaires. Dental students found PBL session interesting and wanted to maintain PBL from the beginning of year 2 up to the end of year 3. Most students reported their participation in discussion during PBL sessions but the level of participation varied. Some of them worked hard to prepare themselves for discussion while others were relatively passive. PBL helped them with in-depth understanding of certain topics and link their basic science knowledge to clinical classes. They felt that guidance from subject specialists and well-prepared facilitators of the sessions were beneficial. The students believed that repetition of triggers from year to year discouraged their active search for learning issues. Majority of the students were undecided or disagreed about the availability of adequate learning resources Most of the students were undecided or disagreed about the availability of adequate learning resources for their self-study. Reviewing and renewing the PBL triggers, providing guidelines for searching for resource materials and briefing the students and facilitators about the philosophy and principles of PBL may make the PBL sessions more beneficial.

Asking the next generation: the implementation of pre-university students’ ideas about physics laboratory preparation exercises

Dunnett, K.; Bartlett, P. A.

2018-01-01

It was planned to introduce online pre-laboratory session activities to a first-year undergraduate physics laboratory course to encourage a minimum level of student preparation for experiments outside the laboratory environment. A group of 16 and 17 year old laboratory work-experience students were tasked to define and design a pre-laboratory activity based on experiments that they had been undertaking. This informed the structure, content and aims of the activities introduced to a first year physics undergraduate laboratory course, with the particular focus on practising the data handling. An implementation study showed how students could try to optimise high grades, rather than gain efficiency-enhancing experience if careful controls were not put in place by assessors. However, the work demonstrated that pre-university and first-year physics students can take an active role in developing scaffolding activities that can help to improve the performance of those that follow their footsteps.

Intelligent tutoring system for clinical reasoning skill acquisition in dental students.

PubMed

Suebnukarn, Siriwan

2009-10-01

Learning clinical reasoning is an important core activity of the modern dental curriculum. This article describes an intelligent tutoring system (ITS) for clinical reasoning skill acquisition. The system is designed to provide an experience that emulates that of live human-tutored problem-based learning (PBL) sessions as much as possible, while at the same time permitting the students to participate collaboratively from disparate locations. The system uses Bayesian networks to model individual student knowledge and activity, as well as that of the group. Tutoring algorithms use the models to generate tutoring hints. The system incorporates a multimodal interface that integrates text and graphics so as to provide a rich communication channel between the students and the system, as well as among students in the group. Comparison of learning outcomes shows that student clinical reasoning gains from the ITS are similar to those obtained from human-tutored sessions.

Language learning without control: the role of the PFC.

PubMed

Friederici, Angela D; Mueller, Jutta L; Sehm, Bernhard; Ragert, Patrick

2013-05-01

Learning takes place throughout lifetime but differs in infants and adults because of the development of the PFC, a brain region responsible for cognitive control. To test this hypothesis, adults were investigated in a language learning paradigm under inhibitory, cathodal transcranial direct current stimulation over PFC. The experiment included a learning session interspersed with test phases and a test-only session. The stimulus material required the learning of grammatical dependencies between two elements in a novel language. In a parallel design, cathodal transcranial direct current stimulation over the left PFC, right PFC, or sham stimulation was applied during the learning session but not during the test-only session. Event-related brain potentials (ERPs) were recorded during both sessions. Whereas no ERP learning effects were observed during the learning session, different ERP learning effects as a function of prior stimulation type were found during the test-only session, although behavioral learning success was equal across conditions. With sham stimulation, the ERP learning effect was reflected in a centro-parietal N400-like negativity indicating lexical processes. Inhibitory stimulation over the left PFC, but not over the right PFC, led to a late positivity similar to that previously observed in prelinguistic infants indicating associative learning. The present data demonstrate that adults can learn with and without cognitive control using different learning mechanisms. In the presence of cognitive control, adult language learning is lexically guided, whereas it appears to be associative in nature when PFC control is downregulated.

2017-09-01

This paper describes the design and outcomes of an educational intervention undertaken to improve the quality of delivery of a fourth-year engineering elective course - Industrial Wastewater and Solid Waste Management at the University of Queensland. The objective was to increase the level of active participation of students in planned active-learning classroom activities, including whole-class discussions and small group project-type work. According to a flipped classroom model, new online material in the form of webcasts was proposed to students before class. Students reacted very positively to the webcasts: the percentage of students viewing the webcast before planned workshop sessions ranged between 80% and 92% over the five weeks of the intervention. Enhanced engagement led also to increased attendance (85-92% at workshop sessions), and remarkable active participation in class (half of observed teams were ∼80% active). Remarkably, team performance as quantified by their report marks linearly correlated with the level of active participation in class.

This study assessed the effectiveness of a learner-centered simulation intervention designed to improve the communication skills of preprofessional sophomore nursing students. An innovative teaching strategy in which communication skills are taught to nursing students by using trained actors who served as standardized family members in a clinical learning laboratory setting was evaluated using a two-group posttest design. In addition to current standard education, the intervention group received a formal training session presenting a framework for communication and a 60-minute practice session with the standardized family members. Four domains of communication-introduction, gathering of information, imparting information, and clarifying goals and expectations-were evaluated in the control and intervention groups in individual testing sessions with a standardized family member. The intervention group performed better than the control group in all four tested domains related to communication skills, and the difference was statistically significant in the domain of gathering information (p = 0.0257).

To examine the effects of Sensorimotor Training to Affect Balance, Engagement, and Learning (STABEL), a virtual reality system to train sensory adaptation for balance control, for children with fetal alcohol spectrum disorders (FASDs). Twenty-three children with FASDs received STABEL training in a university laboratory, or home, or were controls. The Movement Assessment Battery for Children-2nd edition (MABC-2) and Pediatric Clinical Test of Sensory Interaction for Balance-2 (P-CTSIB-2) were analyzed by group (lab, home, and control), session (pre-STABEL, 1 week post-STABEL, and 1 month post-STABEL), and group-by-session interaction. Significant effects were group and session for MABC-2 Balance and interaction for MABC-2 Total Motor and P-CTSIB-2. Preliminary results support improved sensory adaptation, balance, and motor performance post-STABEL, which warrant further study with a larger, randomized sample.

The impact of specially designed digital games-based learning in undergraduate pathology and medical education.

The rapid advances of computer technologies have created a new e-learner generation of "Homo-zappien" students that think and learn differently. Digital gaming is an effective, fun, active, and encouraging way of learning, providing immediate feedback and measurable process. Within the context of ongoing reforms in medical education, specially designed digital games, a form of active learning, are effective, complementary e-teaching/learning resources. To examine the effectiveness of the use of specially designed digital games for student satisfaction and for measurable academic improvement. One hundred fourteen students registered in first-year pathology Medicine 102 had 8 of 16 lecture sessions reviewed in specially designed content-relevant digital games. Performance scores to relevant content sessions were analyzed at midterm and final examinations. Seventy-one students who registered in second-year pathology Medicine 202 were exposed to the games only during the final examination, with the midterm examination serving as an internal matched-control group. Outcome measures included performance at midterm and final examinations. Paired 2-tailed t test statistics compared means. A satisfaction survey questionnaire of yes or no responses analyzed student engagement and their perceptions to digital game-based learning. Questions relevant to the game-play sessions had the highest success rate in both examinations among 114 first-year students. In the 71 second-year students, the examination scores at the end of the final examination were significantly higher than the scores on the midterm examination. Positive satisfaction survey noted increased student engagement, enhanced personal learning, and reduced student stress. Specially constructed digital games-based learning in undergraduate pathology courses showed improved academic performance as measured by examination test scores with increased student satisfaction and engagement.

Beyond Lecture and Non-Lecture Classrooms: LA-student interactions in Active Learning Classrooms

Gonzalez, Dayana; Kornreich, Hagit; Rodriguez, Idaykis; Monslave, Camila; Pena-Flores, Norma

Our expanded multi-site study on active learning classrooms supported by Learning Assistants (LAs) aims to understand the connections between three classroom elements: the activity, student learning, and how LAs support the learning process in the classroom. At FIU, LAs are used in a variety of active learning settings, from large auditorium settings to studio classroom with movable tables. Our study uses the COPUS observation protocol as a way to characterize LAs behaviors in these classrooms. With a focus on LA-student interactions, our analysis of how LAs interact with students during a 'learning session' generated new observational codes for specific new categories of LA roles. Preliminary results show that LAs spend more time interacting with students in some classes, regardless of the classroom setting, while in other classrooms, LA-student interactions are mostly brief. We discuss how LA-student interactions contribute to the dynamics and mechanism of the socially shared learning activity.

Simulation based learning environments are designed to improve the quality of medical education by allowing students to interact with patients, diagnostic laboratory procedures, and patient data in a virtual environment. However, few studies have evaluated whether simulation based learning environments increase students' knowledge, intrinsic motivation, and self-efficacy, and help them generalize from laboratory analyses to clinical practice and health decision-making. An entire class of 300 University of Copenhagen first-year undergraduate students, most with a major in medicine, received a 2-h training session in a simulation based learning environment. The main outcomes were pre- to post- changes in knowledge, intrinsic motivation, and self-efficacy, together with post-intervention evaluation of the effect of the simulation on student understanding of everyday clinical practice were demonstrated. Knowledge (Cohen's d = 0.73), intrinsic motivation (d = 0.24), and self-efficacy (d = 0.46) significantly increased from the pre- to post-test. Low knowledge students showed the greatest increases in knowledge (d = 3.35) and self-efficacy (d = 0.61), but a non-significant increase in intrinsic motivation (d = 0.22). The medium and high knowledge students showed significant increases in knowledge (d = 1.45 and 0.36, respectively), motivation (d = 0.22 and 0.31), and self-efficacy (d = 0.36 and 0.52, respectively). Additionally, 90 % of students reported a greater understanding of medical genetics, 82 % thought that medical genetics was more interesting, 93 % indicated that they were more interested and motivated, and had gained confidence by having experienced working on a case story that resembled the real working situation of a doctor, and 78 % indicated that they would feel more confident counseling a patient after the simulation. The simulation based learning environment increased students' learning, intrinsic motivation, and self-efficacy (although the strength of these effects differed depending on their pre-test knowledge), and increased the perceived relevance of medical educational activities. The results suggest that simulations can help future generations of doctors transfer new understanding of disease mechanisms gained in virtual laboratory settings into everyday clinical practice.

Almost all physicians teach or provide postgraduate medical education from time to time. Although many people assume that there are 'born teachers' and 'those who will never learn to teach', teaching is an ability. The knowledge and skills required to teach well can be learned and practised. In this review article, we present 10 tips that will help the busy clinician to teach effectively. The 10 tips, which are based on the principles of adult learning, are: prepare your teaching session, involve the learners actively, connect to the learners' level of competence, define learning objectives, make the subject of your teaching relevant to the learners, use questions, be a good role model, vary your teaching methods, practise your teaching, and limit the amount of material you are teaching in each session.

Professional learning communities (PLCs) for early childhood science education

Eum, Jungwon

This study explored the content, processes, and dynamics of Professional Learning Community (PLC) sessions. This study also investigated changes in preschool teachers' attitudes and beliefs toward science teaching after they participated in two different forms of PLCs including workshop and face-to-face PLC as well as workshop and online PLC. Multiple sources of data were collected for this study including participant artifacts and facilitator field notes during the PLC sessions. The participants in this study were eight teachers from NAEYC-accredited child care centers serving 3- to 5-year-old children in an urban Midwest city. All teachers participated in a workshop entitled, "Ramps and Pathways." Following the workshop, the first group engaged in face-to-face PLC sessions and the other group engaged in online PLC sessions. Qualitative data were collected through audio recordings, online archives, and open-ended surveys. The teachers' dialogue during the face-to-face PLC sessions was audiotaped, transcribed, and analyzed for emerging themes. Online archives during the online PLC sessions were collected and analyzed for emerging themes. Four main themes and 13 subthemes emanated from the face-to-face sessions, and 3 main themes and 7 subthemes emanated from the online sessions. During the face-to-face sessions, the teachers worked collaboratively by sharing their practices, supporting each other, and planning a lesson together. They also engaged in inquiry and reflection about their science teaching and child learning in a positive climate. During the online sessions, the teachers shared their thoughts and documentation and revisited their science teaching and child learning. Five themes and 15 subthemes emanated from the open-ended survey responses of face-to-face group teachers, and 3 themes and 7 subthemes emanated from the open-ended survey responses of online group teachers. Quantitative data collected in this study showed changes in teachers' attitudes and beliefs toward science teaching. Face-to-face group teachers' comfort with planning and doing different science activities increased significantly after the workshop and after the combination of workshop and face-to-face PLC. This study contributes to the research about various forms of professional development and their process and outcome in early childhood science education and informs early childhood professional communities of creative ways to improve science teaching and learning.

Brain signals measured over a series of experiments have inherent variability because of different physical and mental conditions among multiple subjects and sessions. Such variability complicates the analysis of data from multiple subjects and sessions in a consistent way, and degrades the performance of subject-transfer decoding in a brain-machine interface (BMI). To accommodate the variability in brain signals, we propose 1) a method for extracting spatial bases (or a dictionary) shared by multiple subjects, by employing a signal-processing technique of dictionary learning modified to compensate for variations between subjects and sessions, and 2) an approach to subject-transfer decoding that uses the resting-state activity of a previously unseen target subject as calibration data for compensating for variations, eliminating the need for a standard calibration based on task sessions. Applying our methodology to a dataset of electroencephalography (EEG) recordings during a selective visual-spatial attention task from multiple subjects and sessions, where the variability compensation was essential for reducing the redundancy of the dictionary, we found that the extracted common brain activities were reasonable in the light of neuroscience knowledge. The applicability to subject-transfer decoding was confirmed by improved performance over existing decoding methods. These results suggest that analyzing multisubject brain activities on common bases by the proposed method enables information sharing across subjects with low-burden resting calibration, and is effective for practical use of BMI in variable environments.

Grover, Sumit; Sood, Neena; Chaudhary, Anurag

2017-01-01

Peer-assisted learning (PAL) is a teaching-learning method in which students act as peer teachers and help other students to learn while also themselves learning by teaching. PAL through modified interest building activities (MIBAs) is seldom tried in teaching pathology in medical colleges. This study aimed to evaluate the usefulness of peer teaching using MIBA, obtain feedback from students, and compare different activities with each other and with traditional teaching-learning methods. An interventional pilot study was conducted in 2 months on the 2nd MBBS undergraduates learning pathology at a medical college in North India. Students acted as peer teachers and performed different MIBAs including role plays, demonstration of pathogenesis through props, student-led seminars such as PowerPoint teaching, blackboard teaching, multiple choice question seminars, case-based learning (CBL) exercises, and quizzes before teaching sessions. Feedback was obtained through structured questionnaires on a 5-point Likert scale. Paired t-test was used to compare traditional teaching with MIBAs, and Friedman test was used to compare among different MIBAs. Students found ease of understanding and the interaction and involvement of students as the most important benefits of PAL. MIBAs increased voluntary participation, coordination, teamwork, shared responsibility, and group dynamics among students. Quiz sessions followed by PowerPoint seminars and prop demonstrations received highest mean scores from students on most of the parameters. Quizzes, blackboard teaching, prop activities, and CBL helped students understand topics better and generated interest. Learners advocated for making MIBAs and PAL compulsory for future students. PAL complemented by MIBAs may be adopted to make teaching-learning more interesting and effective through the active involvement and participation of students.

Closing the feedback loop: engaging students in large first-year mathematics test revision sessions using pen-enabled screens

How can active learning, peer learning and prompt feedback be achieved in large first-year mathematics classes? Further, what technologies may support these aims? In this article, we assert that test revision sessions in first-year mathematics held in a technology-enhanced lecture theatre can be highly interactive with students solving problems, learning from each other and receiving immediate feedback. This is facilitated by pen-enabled screens and synchronization software. We argue that the educational benefits achievable through the technology do outweigh the technological distractions, and that these benefits can be achieved by focused, targeted one-off sessions and not only by a semester-long, regular approach. Repeat mid-semester test revision sessions were offered on a non-compulsory basis using pen-enabled screens for all students. Students worked practice test questions and marked solutions to mathematical problems on the screens. Students' work was then displayed anonymously for their peers to see. Answers were discussed with the whole class. We discuss outcomes from two offerings of these sessions using student feedback and lecturer reflections and show the impact of participation on self-reported student confidence. Pedagogical approaches that the technology allowed for the first time in a large class are highlighted. Students responded uniformly positively.

On-line interactive virtual experiments on nanoscience

Kadar, Manuella; Ileana, Ioan; Hutanu, Constantin

2009-01-01

This paper is an overview on the next generation web which allows students to experience virtual experiments on nano science, physics devices, processes and processing equipment. Virtual reality is used to support a real university lab in which a student can experiment real lab sessions. The web material is presented in an intuitive and highly visual 3D form that is accessible to a diverse group of students. Such type of laboratory provides opportunities for professional and practical education for a wide range of users. The expensive equipment and apparatuses that build the experimental stage in a particular standard laboratory is used to create virtual educational research laboratories. Students learn how to prepare the apparatuses and facilities for the experiment. The online experiments metadata schema is the format for describing online experiments, much like the schema behind a library catalogue used to describe the books in a library. As an online experiment is a special kind of learning object, one specifies its schema as an extension to an established metadata schema for learning objects. The content of the courses, metainformation as well as readings and user data are saved on the server in a database as XML objects.

Technology has been widely involved in science research. Researchers are now applying it to science education in an attempt to bring students’ science activities closer to authentic science activities. The present study synthesizes the research to discuss the development of technology-enhanced laboratories and how technology may contribute to fulfilling the instructional objectives of laboratories in physics. To be more specific, this paper discusses the engagement of technology to innovate physics laboratories and the potential of technology to promote inquiry, instructor and peer interaction, and learning outcomes. We then construct a framework for teachers, scientists, and programmers to guide and evaluate technology-integrated laboratories. The framework includes inquiry learning and openness supported by technology, ways of conducting laboratories, and the diverse learning objectives on which a technology-integrated laboratory may be focused.

2007-12-01

This presentation will highlight interactive on-line curriculum developed at the Cooperative Institute for Meteorological Satellite Studies (CIMSS) at the University of Wisconsin in Madison. CIMSS has been on the forefront of educational software design for over two decades, routinely integrating on-line activities into courses on satellite remote sensing. In 2006, CIMSS began collaborating with education experts and researchers from the University of Washington to create an NSF-funded distance learning course for science teachers called Satellite Applications for Geoscience Education. This course includes numerous web-based learning activities, including a distance education tool called VISITview which allows instructors to connect with multiple students simultaneously to conduct a lesson. Developed at CIMSS to facilitate training of National Weather Service forecasters economically and remotely, VISITview is especially effective for groups of people discussing and analyzing maps or images interactively from many locations. Along with an on-line chat function, VISITview participants can use a speaker phone or a networked voice-enabled application to create a learning environment similar to a traditional classroom. VISITview will be used in two capacities: first, instructors will convey topics of current relevance in geoscience disciplines via VISITview. Second, the content experts will participate in "virtual visits" to the classrooms of the educators who take the course for full credit. This will enable scientists to interact with both teachers and students to answer questions and discuss exciting or inspiring examples that link satellite data to their areas of research. As long as a school has Internet access, an LCD projector and a speakerphone, VISITview sessions can be shared with an entire classroom. The geoscientists who developed material for the course and conducting VISITview lectures include a geologist from the University of Wisconsin-Richland, an oceanographer from the Applied Physics Laboratory at the University of Washington, and satellite meteorology experts from CIMSS at UW-Madison. This AGU presentation will report on the progress of the debut semester of the geoscience course and corresponding VISITview sessions.

Memory extinction involves the formation of a new associative memory that inhibits a previously conditioned association. Nonetheless, it could also depend on weakening of the original memory trace if extinction is assumed to have multiple components. The phosphatase calcineurin (CaN) has been described as being involved in extinction but not in the initial consolidation of fear learning. With this in mind, we set to study whether CaN could have different roles in distinct components of extinction. Systemic treatment with the CaN inhibitors cyclosporin A (CsA) or FK-506, as well as i.c.v. administration of CsA, blocked within-session, but not between-session extinction or initial learning of contextual fear conditioning. Similar effects were found in multiple-session extinction of contextual fear conditioning and in auditory fear conditioning, indicating that CaN is involved in different types of short-term extinction. Meanwhile, inhibition of protein synthesis by cycloheximide (CHX) treatment did not affect within-session extinction, but disrupted fear acquisition and slightly impaired between-session extinction. Our results point to a dissociation of within- and between-session extinction of fear conditioning, with the former being more dependent on CaN activity and the latter on protein synthesis. Moreover, the modulation of within-session extinction did not affect between-session extinction, suggesting that these components are at least partially independent. PMID:25691516

Neurofeedback is widely applied as non-pharmacological intervention aimed at reducing symptoms of ADHD, even though efficacy has not been unequivocally established. Neuronal changes during the neurofeedback intervention that resemble learning can provide crucial evidence for the feasibility and specificity of this intervention. A total of 38 children (aged between 7 and 13 years) with a DSM-IV-TR diagnosis of ADHD, completed on average 29 sessions of theta (4-8 Hz)/beta (13-20 Hz) neurofeedback training. Dependent variables included training-related measures as well as theta and beta power during baseline and training runs for each session. Learning effects were analyzed both within and between sessions. To further specify findings, individual learning curves were explored and correlated with behavioral changes in ADHD symptoms. Over the course of the training, there was a linear increase in participants' mean training level, highest obtained training level and the number of earned credits (range b = 0.059, -0.750, p < 0.001). Theta remained unchanged over the course of the training, while beta activity increased linearly within training sessions (b = 0.004, 95% CI = [0.0013-0.0067], p = 0.005) and over the course of the intervention (b = 0.0052, 95% CI = [0.0039-0.0065], p < 0.001). In contrast to the group analyses, significant individual learning curves were found for both theta and beta over the course of the intervention in 39 and 53%, respectively. Individual learning curves were not significantly correlated with behavioral changes. This study shows that children with ADHD can gain control over EEG states during neurofeedback, although a lack of behavioral correlates may indicate insufficient transfer to daily functioning, or to confounding reinforcement of electromyographic activity. This trial is registered at the US National Institutes of Health (ClinicalTrials.gov, ref. no: NCT01363544); https://clinicaltrials.gov/show/NCT01363544 .

Laboratory experiences are essential for optics education. However, college students have limited access to advanced optical equipment that is generally expensive and complicated. Hence there is a need for innovative solutions to expose students to advanced optics laboratories. Here we describe a novel approach, interactive virtual optical laboratory (IVOL) that allows unlimited number of students to participate the lab session remotely through internet, to improve laboratory education in photonics. Although students are not physically conducting the experiment, IVOL is designed to engage students, by actively involving students in the decision making process throughout the experiment.

Medical school 2.0: How we developed a student-generated question bank using small group learning.

PubMed

Gooi, Adrian C C; Sommerfeld, Connor S

The multiple-choice question (MCQ) is one of the most common methods for formative and summative assessment in medical school. Common challenges with this format include (1) creating vetted questions and (2) involving students in higher-order learning activities. Involving medical students in the creation of MCQs may ameliorate both of these challenges. What we did: We used a small group learning structure to develop a student-generated question bank. Students created their own MCQ based on self-study materials, and then reviewed each other's questions within small groups. Selected questions were reviewed with the class as a whole. All questions were later vetted by the instructor and incorporated into a question bank that students could access for formative learning. Post-session survey indicated that 91% of the students felt that the class-created MCQ question bank was a valuable resource, and 86% of students would be interested in collaborating with the class for creating practice questions in future sessions. Developing a student-generated question bank can improve the depth and interactivity of student learning, increase session enjoyment and provide a potential resource for student assessment.

Training medical students to communicate with a linguistic minority group.

PubMed

Drouin, Jeanne; Rivet, Christine

2003-06-01

Effective communication is central to a successful physician-patient relationship. Communication is usually enhanced when the linguistic and cultural attributes of patients are incorporated in health care delivery. With this purpose in mind, the Faculty of Medicine at the University of Ottawa has developed a French-language stream to train future physicians for the francophone minority population of Ontario. As part of this project, a communication skills laboratory was created for francophone students in 1996, since all three tertiary care teaching hospitals operated in English only. The laboratory consists of a controlled environment where francophone students conduct interviews in French while being observed by clinicians trained in observation and feedback techniques. It makes use of simulated patients trained to play specific roles and to give feedback to students. Laboratory sessions take place throughout the first and second years and expose students to 15 scenarios covering different themes in each year. Each scenario includes a communication problem. Facilities are in place for filming the encounters for review by students. The project has had favorable outcomes. Both students and clinician-supervisors find that the laboratory offers an excellent learning environment and describe the cases as realistic and instructive. Clerkship preceptors are pleased with the students' communication skills. Because of the success of the laboratory, faculty authorities plan to translate the scenarios and offer similar sessions to students in the English-language stream. The teaching methods used in the communication skills laboratory may be of interest to other medical schools that serve linguistic minority populations.

Basic steps in establishing effective small group teaching sessions in medical schools.

Meo, Sultan Ayoub

2013-07-01

Small-group teaching and learning has achieved an admirable position in medical education and has become more popular as a means of encouraging the students in their studies and enhance the process of deep learning. The main characteristics of small group teaching are active involvement of the learners in entire learning cycle and well defined task orientation with achievable specific aims and objectives in a given time period. The essential components in the development of an ideal small group teaching and learning sessions are preliminary considerations at departmental and institutional level including educational strategies, group composition, physical environment, existing resources, diagnosis of the needs, formulation of the objectives and suitable teaching outline. Small group teaching increases the student interest, teamwork ability, retention of knowledge and skills, enhance transfer of concepts to innovative issues, and improve the self-directed learning. It develops self-motivation, investigating the issues, allows the student to test their thinking and higher-order activities. It also facilitates an adult style of learning, acceptance of personal responsibility for own progress. Moreover, it enhances student-faculty and peer-peer interaction, improves communication skills and provides opportunity to share the responsibility and clarify the points of bafflement.

Modification of persistent responses in medial prefrontal cortex during learning in trace eyeblink conditioning

PubMed Central

2014-01-01

Persistent spiking in response to a discrete stimulus is considered to reflect the active maintenance of a memory for that stimulus until a behavioral response is made. This response pattern has been reported in learning paradigms that impose a temporal gap between stimulus presentation and behavioral response, including trace eyeblink conditioning. However, it is unknown whether persistent responses are acquired as a function of learning or simply represent an already existing category of response type. This fundamental question was addressed by recording single-unit activity in the medial prefrontal cortex (mPFC) of rabbits during the initial learning phase of trace eyeblink conditioning. Persistent responses to the tone conditioned stimulus were observed in the mPFC during the very first training sessions. Further analysis revealed that most cells with persistent responses showed this pattern during the very first training trial, before animals had experienced paired training. However, persistent cells showed reliable decreases in response magnitude over the first training session, which were not observed on the second day of training or for sessions in which learning criterion was met. This modification of response magnitude was specific to persistent responses and was not observed for cells showing phasic tone-evoked responses. The data suggest that persistent responses to discrete stimuli do not require learning but that the ongoing robustness of such responses over the course of training is modified as a result of experience. Putative mechanisms for this modification are discussed, including changes in cellular or network properties, neuromodulatory tone, and/or the synaptic efficacy of tone-associated inputs.

2018-01-01

The purpose of this study was to investigate sustained attention through modulation of the fronto-cerebral network with transcranial direct current stimulation (tDCS) in adults with attention-deficit/hyperactivity disorder (ADHD) and control participants. Thirty-seven participants (21 with ADHD) underwent three separate sessions (baseline, active tDCS, and sham) and performed the MOXO Continuous Performance Test (CPT). We applied double anodal stimulation of 1.8 mA tDCS for 20 min over the left and right dorsolateral prefrontal cortex (DLPFC), with the cathode over the cerebellum. Baseline session revealed significant differences between ADHD and control participants in the MOXO-CPT attention and hyperactivity scores, validating the MOXO as a diagnostic tool. However, there were no tDCS effects in most MOXO-CPT measures, except hyperactivity, due to a significant learning effect. We conclude that learning and repetition effects in cognitive tasks need to be considered when designing within-subjects tDCS experiments, as there are natural improvements between sessions that conceal potential stimulation effects.

To implement active-learning exercises in a required pharmacy course and assess their impact on students' knowledge and confidence in identifying and communicating with patients with low health literacy, as part of a required course in cultural competency, health literacy, and health beliefs. Active-learning activities including administering health literacy assessments, identifying informal signs of low health literacy, conducting mock patient counseling sessions, rating the readability of drug information, analyzing information in drug advertisements, and writing patient education materials were incorporated into the 6-sesssion health literacy portion of the course. A pretest and posttest showed that students' knowledge of health literacy increased, and a retrospective pretest found improvement in students' confidence in their ability to care for patients with low health literacy. In-class discussions provided informal evidence that students gained new knowledge from the active-learning activities. The addition of active-learning activities was effective in teaching health literacy concepts to pharmacy students.

Childhood overweight is disproportionately worse in minority and low-income populations. Theater is a promising and effective tool for delivering health education to these underserved populations, but no known studies have examined the use of theater to promote both nutrition and physical activity to minority youth. To develop an interactive, theater-based intervention that conveys health messages to low-income, urban, African Americans and engages them in learning ways to adopt a healthy lifestyle. Community partners worked to develop a theater-based nutrition and physical activity intervention. A focus group provided urban adolescents' thoughts about their desires for the intervention. Based on input from all community partners, the group created a theater-based intervention. Researchers used a quasi-experimental (pre-/posttest) design with a community-based participatory research (CBPR) approach. Participants learned health messages through theater, dance, and music and gave feedback on the program sessions and materials. The program ended with a dinner theater performance showcasing information that students learned during the intervention. Participants received six theater-based health lessons. Learning objectives for each health education session were achieved. Each participant contributed to and performed in the final performance. All program participants were highly satisfied with the theater-based method of learning health messages. A community-academic partnership succeeded in developing a theater-based nutrition and physical activity intervention that satisfied participating adolescents.

Addressing key concepts in physical geography through interactive learning activities in an online geo-ICT environment

2016-04-01

The increasing number of geospatial datasets and free online geo-ICT tools offers new opportunities for education in Earth Sciences. Geospatial technology indeed provides an environment through which interactive learning can be introduced in Earth Sciences curricula. However, the effectiveness of such e-learning approaches in terms of learning outcomes has rarely been addressed. Here, we present our experience with the implementation of digital interactive learning activities within an introductory Physical Geography course attended by 90 undergraduate students in Geography, Geology, Biology and Archaeology. Two traditional lectures were replaced by interactive sessions (each 2 h) in a flexible classroom where students had to work both in team and individually in order to explore some key concepts through the integrated use of geospatial data within Google EarthTM. A first interactive lesson dealt with the classification of river systems and aimed to examine the conditions under which rivers tend to meander or to develop a braided pattern. Students were required to collect properties of rivers (river channel pattern, channel slope, climate, discharge, lithology, vegetation, etc). All these data are available on a global scale and have been added as separate map layers in Google EarthTM. Each student collected data for at least two rivers and added this information to a Google Drive Spreadsheet accessible to the entire group. This resulted in a database of more than one hundred rivers spread over various environments worldwide. In a second phase small groups of students discussed the potential relationships between river channel pattern and its controlling factors. Afterwards, the findings of each discussion group were presented to the entire audience. The same set-up was followed in a second interactive session to explore spatial variations in ecosystem properties such as net primary production and soil carbon content. The qualitative evaluation of both interactive sessions showed that the majority of students perceive these as very useful and inspiring. Students were more capable in exploring the spatial linkages between various environmental variables and processes compared to traditional lectures. Furthermore, the format of the sessions offered a forum in which undergraduate students from a variety of disciplines discussed the learning content in mixed groups. The success of interactive learning activities, however, strongly depends on the quality of the educational infrastructure (flexible spaces, wireless connections with sufficient broadband capacity).

The objectives of this curricular innovation project were to implement a flipped classroom curriculum for the gynaecologic oncology topics of the obstetrics and gynaecology medical student clerkship, and to evaluate student satisfaction with the change. Four short online videos on the topics of endometrial hyperplasia, cervical dysplasia, evaluation of an adnexal mass, and ovarian cancer were created, and students were instructed to view them prior to a class-time active learning session. The Learning Activity Management System (lams) open-source online platform was used to create an active learning class-time activity that consisted of a coached discussion of cases. Student satisfaction with the two aspects of the flipped curriculum was obtained. In addition, lecture assessment for the gynaecologic oncology topics and aggregate student performance on the gynaecological oncology questions of the US National Board of Medical Examiners (NBME) Subject Examination were compared before and after implementation of the curriculum. Eighty-nine students rotated on the clerkship during the pilot period of analysis. Seventy-one students (80%) viewed the videos prior to the class session, and 84 (94%) attended the session. Student satisfaction was very high for both parts of the curriculum. There was no significant difference in aggregate student performance on the gynaecological oncology questions of the NBME Subject Examination. The flipped classroom curriculum demonstrates a promising platform for using technology to make better use of students' time Our implementation of the flipped classroom curriculum for the gynaecologic oncology topics successfully demonstrates a promising platform for using technology to make better use of our students' time, and for increasing their satisfaction with the necessary didactic learning of the clerkship. © 2015 John Wiley & Sons Ltd.

The acquisition of cognitive, affective and psychomotor knowledge and skills are required in nursing, made possible via an interactive teaching method, such as simulation. This study conducted to identify the impact of simulation on first-year nursing students' ability to learn vital signs. A convenience sample of 90 first-year nursing students enrolled at a University, Ankara, in 2014-2015. Ninety students enrolled for lessons on the "Fundamentals of Nursing" were identified using a simple random sampling method. The students were taught vital signs theory via traditional methods. They were grouped into experimental 1, experimental 2 and control group, of 30 students each. Students in the experimental 1 group attended sessions on simulation and those in the experimental 2 group sessions on laboratory work, followed by simulation. The control group were taught via traditional methods and only attended the laboratory work sessions. The students' cognitive knowledge acquisition was evaluated using a knowledge test before and after the lessons. The ability to measure vital signs in adults (healthy ones and patients) was evaluated using a skill control list. A statistically significant difference was not observed between the groups in terms of the average pre-test scores on knowledge (p>0.050). Groups exposed to simulation obtained statistically significantly higher scores than the control group in post-test knowledge (p<0.050). The ability of the groups exposed to simulation to measure vital signs in healthy adults and patients was more successful than that the control group (p<0.050). This was statistically significant. Simulation had a positive effect on the ability of nursing students to measure vital signs. Thus, simulation should be included in the mainstream curriculum in order to effectively impart nursing knowledge and skills. Copyright © 2017 Elsevier Ltd. All rights reserved.

Objective: Medical Education Journal Club is an evidence-based approach to teach and learn critical appraisal techniques on available literature. This study evaluates the implementation and experience of two academic years of Journal club at Medical Education Department, King Saud University. Methods: We started JC in 2015 at medical education department, KSU. An invitation with a published paper and event poster were sent 2 weeks prior of the session to participants. A traditional one-group posttest design with open item survey were conducted at the end of every session. Results: A total of 12 sessions were conducted in total. The average attendance of 26 (Male: 42/79, 53.1%) and (Female: 31/79, 39.2%) with mix of professors, associate and assistant professors. The MEJC had a positive effect on participant’s session expectations (45/79, 92.4%), and had increased their knowledge of the field (73/79, 92.4%). It was observed that the attendance of event depends on the speaker for the event. The sessions have also arisen the need of trainings and other scientific activities. Conclusions: MEJC is an educational activity that can play important aspect in providing high quality healthcare teachings. We conclude that the success and consistency of MEJC depends on speaker. It commensurate the audience interest to attend and learn. While proper advertisement of event, and regular attendance also plays a vital role in this regard. PMID:29142580

This study was designed to further assess cognitive and affective functioning in a mouse model of Fragile X syndrome (FXS), the Fmr1(tm1Cgr) or Fmr1 "knockout" (KO) mouse. Male KO mice and wild-type littermate controls were tested on learning set and reversal learning tasks. The KO mice were not impaired in associative learning, transfer of learning, or reversal learning, based on measures of learning rate. Analyses of videotapes of the reversal learning task revealed that both groups of mice exhibited higher levels of activity and wall-climbing during the initial sessions of the task than during the final sessions, a pattern also seen for trials following an error relative to those following a correct response. Notably, the increase in both behavioral measures seen early in the task was significantly more pronounced for the KO mice than for controls, as was the error-induced increase in activity level. This pattern of effects suggests that the KO mice reacted more strongly than controls to the reversal of contingencies and pronounced drop in reinforcement rate, and to errors in general. This pattern of effects is consistent with the heightened emotional reactivity frequently described for humans with FXS. (c) 2008 Wiley Periodicals, Inc.

Predicting reading and mathematics from neural activity for feedback learning.

Peters, Sabine; Van der Meulen, Mara; Zanolie, Kiki; Crone, Eveline A

2017-01-01

Although many studies use feedback learning paradigms to study the process of learning in laboratory settings, little is known about their relevance for real-world learning settings such as school. In a large developmental sample (N = 228, 8-25 years), we investigated whether performance and neural activity during a feedback learning task predicted reading and mathematics performance 2 years later. The results indicated that feedback learning performance predicted both reading and mathematics performance. Activity during feedback learning in left superior dorsolateral prefrontal cortex (DLPFC) predicted reading performance, whereas activity in presupplementary motor area/anterior cingulate cortex (pre-SMA/ACC) predicted mathematical performance. Moreover, left superior DLPFC and pre-SMA/ACC activity predicted unique variance in reading and mathematics ability over behavioral testing of feedback learning performance alone. These results provide valuable insights into the relationship between laboratory-based learning tasks and learning in school settings, and the value of neural assessments for prediction of school performance over behavioral testing alone.

A trial of team-based versus small-group learning for second-year medical students: does the size of the small group make a difference?

PubMed

Willett, Laura Rees; Rosevear, G Craig; Kim, Sarang

2011-01-01

Team-based learning is a large-group instructional modality intended to provide active learning with modest faculty resources. The goal is to determine if team-based learning could be substituted for small-group learning in case sessions without compromising test performance or satisfaction. One hundred and sixty-seven students were assigned to team-based or small-group learning for 6 case discussion sessions. Examination scores and student satisfaction were compared. Instruction modality had no meaningful effect on examination score, 81.7% team based versus 79.7% small-group, p=.56 after multivariate adjustment. Student satisfaction was lower with team-based learning, 2.45 versus 3.74 on a 5-point scale, p<.001. Survey responses suggested that the very small size (8-10 students) of our small groups influenced the preference for small-group learning. Team-based learning does not adversely affect examination performance. However, student satisfaction may be inferior, especially if compared to instruction in very small groups of 10 or fewer students.

2013-08-12

To assess the integration of problem-based learning and technology into a self-care course. Problem-based learning (PBL) activities were developed and implemented in place of lectures in a self-care course. Students used technology, such as computer-generated virtual patients and iPads, during the PBL sessions. Students' scores on post-case quizzes were higher than on pre-case quizzes used to assess baseline knowledge. Student satisfaction with problem-based learning and the use of technology in the course remained consistent throughout the semester. Integrating problem-based learning and technology into a self-care course enabled students to become active learners.

Healthy women do not always consume Recommended Daily Levels of fluid intake ad libitum. We hypothesized that 1) women lose≥1.0% BW during daily activities, 2) that mild body water loss impairs memory and executive function, 3) water intake to recommended daily levels will improve cognitive function. We tested 12 women (26±5yr, 22.5±2.6kg/m 2 BMI). Session 1 was a control (CON) session, during which subjects monitored their food and fluid intake (diary) and activity (Fitbit®). The next two sessions were applied in balanced order: dehydration (DEH) session, where subjects minimized drinking, and a euhydration (EUH) session, where subjects drank Recommended Daily Levels of fluid for their age and sex, or 2500ml/24h. We compared emotion, sensory perception and cognition with computer based visual analog tests and computer based cognitive tasks (Cogstate) at 5PM, i.e. baseline (BL) on the evening prior to the session, and at 7AM, 12PM, and 5PM during the session. Urine specific gravity (USG) was similar at BL across conditions (CON 1.013±0.002, DEH 1.015±0.002, EUH 1.014±0.002) and increased with dehydration (CON 1.011±0.003, DEH 1.021±0.002, EUH 1.010±0.002, P<0.05) by 5PM of the session. Uncontrolled fluid intake and physical activity were similar across sessions. The water challenges did not impact Detection, Identification, One-Card Learning, but EUH improved visual and working memory (Groton Maze Learning Test) errors: CON 40.1±11.1, DEH 40.5±10.1, EUH 33.9±10.9, P<0.05. Executive function [Set Shifting (SETS)] also improved under EUH, errors: BL 22.5±12.7 vs. 5PM 17.8±6.2, P<0.05. Mild dehydration caused deficits in visual and working memory and executive function in healthy young women. These deficits were reversed by drinking water to the European Food Safety Authority and Institute of Medicine requirements of 2.5l/day for adult women. Copyright © 2017 Elsevier Inc.

Strategies for teaching pathology to graduate students and allied health professionals.

PubMed

Fenderson, Bruce A

2005-02-01

Pathology is an essential course for many students in the biomedical sciences and allied health professions. These students learn the language of pathology and medicine, develop an appreciation for mechanisms of disease, and understand the close relationship between basic research and clinical medicine. We have developed 3 pathology courses to meet the needs of our undergraduates, graduate students, and allied health professionals. Through experience, we have settled on an approach to teaching pathology that takes into account the diverse educational backgrounds of these students. Educational resources such as assigned reading, online homework, lectures, and review sessions are carefully balanced to adjust course difficulty. Common features of our pathology curricula include a web-based computer laboratory and review sessions on the basis of selected pathology images and open-ended study questions. Lectures, computer-guided homework, and review sessions provide the core educational content for undergraduates. Graduate students, using the same computer program and review material, rely more heavily on assigned reading for core educational content. Our experience adapting a pathology curriculum to the needs of divergent groups of students suggests a general strategy for monitoring course difficulty. We hypothesize that course difficulty is proportional to the information density of specific learning resources (eg, lecture or textbook) multiplied by the weight of those learning resources placed on examinations. This formula allows educators to match the difficulty of a course with the educational needs of students, and provides a useful tool for longitudinal studies of curriculum reform.

Parietotemporal Stimulation Affects Acquisition of Novel Grapheme-Phoneme Mappings in Adult Readers

PubMed Central

Younger, Jessica W.; Booth, James R.

2018-01-01

Neuroimaging work from developmental and reading intervention research has suggested a cause of reading failure may be lack of engagement of parietotemporal cortex during initial acquisition of grapheme-phoneme (letter-sound) mappings. Parietotemporal activation increases following grapheme-phoneme learning and successful reading intervention. Further, stimulation of parietotemporal cortex improves reading skill in lower ability adults. However, it is unclear whether these improvements following stimulation are due to enhanced grapheme-phoneme mapping abilities. To test this hypothesis, we used transcranial direct current stimulation (tDCS) to manipulate parietotemporal function in adult readers as they learned a novel artificial orthography with new grapheme-phoneme mappings. Participants received real or sham stimulation to the left inferior parietal lobe (L IPL) for 20 min before training. They received explicit training over the course of 3 days on 10 novel words each day. Learning of the artificial orthography was assessed at a pre-training baseline session, the end of each of the three training sessions, an immediate post-training session and a delayed post-training session about 4 weeks after training. Stimulation interacted with baseline reading skill to affect learning of trained words and transfer to untrained words. Lower skill readers showed better acquisition, whereas higher skill readers showed worse acquisition, when training was paired with real stimulation, as compared to readers who received sham stimulation. However, readers of all skill levels showed better maintenance of trained material following parietotemporal stimulation, indicating a differential effect of stimulation on initial learning and consolidation. Overall, these results indicate that parietotemporal stimulation can enhance learning of new grapheme-phoneme relationships in readers with lower reading skill. Yet, while parietotemporal function is critical to new learning, its role in continued reading improvement likely changes as readers progress in skill. PMID:29628882

Diminished Neural Adaptation during Implicit Learning in Autism

Schipul, Sarah E.; Just, Marcel Adam

2015-01-01

Neuroimaging studies have shown evidence of disrupted neural adaptation during learning in individuals with autism spectrum disorder (ASD) in several types of tasks, potentially stemming from frontal-posterior cortical underconnectivity (Schipul et al., 2012). The aim of the current study was to examine neural adaptations in an implicit learning task that entails participation of frontal and posterior regions. Sixteen high-functioning adults with ASD and sixteen neurotypical control participants were trained on and performed an implicit dot pattern prototype learning task in a functional magnetic resonance imaging (fMRI) session. During the preliminary exposure to the type of implicit prototype learning task later to be used in the scanner, the ASD participants took longer than the neurotypical group to learn the task, demonstrating altered implicit learning in ASD. After equating task structure learning, the two groups’ brain activation differed during their learning of a new prototype in the subsequent scanning session. The main findings indicated that neural adaptations in a distributed task network were reduced in the ASD group, relative to the neurotypical group, and were related to ASD symptom severity. Functional connectivity was reduced and did not change as much during learning for the ASD group, and was related to ASD symptom severity. These findings suggest that individuals with ASD show altered neural adaptations during learning, as seen in both activation and functional connectivity measures. This finding suggests why many real-world implicit learning situations may pose special challenges for ASD. PMID:26484826

Competency-based education in health care requires rigorous standards to ensure professional proficiency. Demonstrating competency in hands-on laboratories calls for effective preparation, knowledge, and experience, all of which can be difficult to achieve using traditional teaching methods. Virtual laboratories are an alternative, cost-effective approach to providing students with sufficient preparatory information. Research on the use of virtual labs in allied health education is limited. The current study investigated the benefits, challenges, and perceived impact of a virtual lab in an allied health program. The sample consisted of 64 students (55 females, 9 males) enrolled in a university medical laboratory science program. A convergent mixed-methods approach (Likert survey, open-ended questions, think-aloud protocol data) revealed that students had positive attitudes towards visual learning, authenticity, learner control, organization, and scaffolding afforded by the virtual lab. Challenges reported included navigational difficulties, an absence of control over content selection, and lack of understanding for certain concepts. Over 90% of students agreed that the virtual lab helped them prepare for hands-on laboratory sessions and that they would use this format of instruction again. Overall, 84% of the students agreed that the virtual lab helped them to achieve greater success in learning.

Human teaching is a social interaction that supports reciprocal and dynamical feedback between the teacher and the student. The prefrontal cortex (PFC) is a region of particular interest due to its demonstrated role in social interaction. In the present study, we evaluated the PFC activity simultaneously in two individuals playing the role of a teacher and student in a video game teaching–learning task. For that, we used two wearable near-infrared spectroscopy (NIRS) devices in order to elucidate the neural mechanisms underlying cognitive interactions between teachers and students. Fifteen teacher–student pairs in total (N = 30) participated in this study. Each teacher was instructed to teach the video game to their student partner, without speaking. The PFC activity was simultaneously evaluated in both participants using a wearable 16-channel NIRS system during the video game teaching–learning task. Two sessions, each including a triplet of a 30-s teaching–learning task, were performed in order to evaluate changes in PFC activity after advancement of teaching–learning state. Changes in the teachers’ left PFC activity between the first and second session positively correlated with those observed in students (r = 0.694, p = 0.004). Moreover, among teachers, multiple regression analysis revealed a correlation between the left PFC activity and the assessment gap between one’s own teaching and the student’s understanding (β = 0.649, p = 0.009). Activity in the left PFC changed synchronously in both teachers and students after advancement of the teaching–learning state. The left PFC of teachers may be involved in integrating information regarding one’s own teaching process and the student’s learning state. The present observations indicate that simultaneous recording and analysis of brain activity data during teacher–student interactions may be useful in the field of educational neuroscience.

The effect of participation in an extended inquiry project on general chemistry student laboratory interactions, confidence, and process skills

Krystyniak, Rebecca A.

2001-12-01

This study explored the effect of participation by second-semester general chemistry students in an extended open-inquiry laboratory investigation on their use of science process skills and confidence in performing specific aspects of laboratory investigations. In addition, verbal interactions of a student lab team among team members and with their instructor over three open-inquiry laboratory sessions and two non-inquiry sessions were investigated. Instruments included the Test of Integrated Skills (TIPS), a 36-item multiple-choice instrument, and the Chemistry Laboratory Survey (CLS), a researcher co-designed 20-item 8-point instrument. Instruments were administered at the beginning and close of the semester to 157 second-semester general chemistry students at the two universities; students at only one university participated in open-inquiry activity. A MANCOVA was performed to investigate relationships among control and experimental students, TIPS, and CLS post-test scores. Covariates were TIPS and CLS pre-test scores and prior high school and college science experience. No significant relationships were found. Wilcoxen analyses indicated both groups showed increase in confidence; experimental-group students with below-average TIPS pre-test scores showed a significant increase in science process skills. Transcribed audio tapes of all laboratory-based verbal interactions were analyzed. Coding categories, developed using the constant comparison method, led to an inter-rater reliability of .96. During open-inquiry activities, the lab team interacted less often, sought less guidance from their instructor, and talked less about chemistry concepts than during non-inquiry activities. Evidence confirmed that students used science process skills and engaged in higher-order thinking during both types of activities. A four-student focus shared their experiences with open-inquiry activities, indicating that they enjoyed the experience, viewed it as worthwhile, and believed it helped them gain understanding of the nature of chemistry research. Research results indicate that participation in open-inquiry laboratory increases student confidence and, for some students, the ability to use science process skills. Evidence documents differences in student laboratory interactions and behavior that are attributable to the type of laboratory experience. Further research into aspects of open-inquiry laboratory experiences is recommended.

Rationale/Objectives This study examined the effects of propranolol vs. placebo, administered immediately after a 'retrieval' session of cocaine cue exposure (CCE), on craving and physiological responses occurring 24 hr. later during a subsequent 'test' session of CCE. It was hypothesized that compared to placebo-treated cocaine-dependent (CD) individuals, propranolol-treated CD individuals would evidence attenuated craving and physiological reactivity during the test session. Secondarily, it was expected that group differences identified in the test session would be evident at a 1-week follow-up CCE session. Exploratory analyses of treatment effects on cocaine use were also performed at follow-up. Methods CD participants received either 40 mg propranolol or placebo immediately following a 'retrieval' CCE session. The next day, participants received a 'test' session of CCE that was identical to the 'retrieval' session except no medication was administered. Participants underwent a ‘follow-up’ CCE session 1-week later. Craving and other reactivity measures were obtained at multiple time points during the CCE sessions. Results Propranolol- vs. placebo-treated participants evidenced significantly greater attenuation of craving and cardiovascular reactivity during the test session. Analysis of the follow-up CCE session data did not reveal any group differences. Although there was no evidence of treatment effects on cocaine use during follow-up, this study was insufficiently powered to rigorously evaluate differential cocaine use. Conclusions This double-blind, placebo-controlled laboratory study provides the first evidence that propranolol administration following CCE may modulate memories for learning processes that subserve cocaine craving/cue reactivity in CD humans. Alternative interpretations of the findings were considered and implications of the results for treatment were noted. PMID:23460266

Metabotropic glutamate receptor 5 (mGluR5) plays important roles in modulating neural activity and plasticity and has been associated with several neuropathological disorders. Previous work has shown that genetic ablation or pharmacological inhibition of mGluR5 disrupts fear extinction and spatial reversal learning, suggesting that mGluR5 signaling is required for different forms of adaptive learning. Here, we tested whether ADX47273, a selective positive allosteric modulator (PAM) of mGluR5, can enhance adaptive learning in mice. We found that systemic administration of the ADX47273 enhanced reversal learning in the Morris Water Maze, an adaptive task. In addition, we found that ADX47273 had no effect on single-session and multi-session extinction, but administration of ADX47273 after a single retrieval trial enhanced subsequent fear extinction learning. Together these results demonstrate a role for mGluR5 signaling in adaptive learning, and suggest that mGluR5 PAMs represent a viable strategy for treatment of maladaptive learning and for improving behavioral flexibility.

Both preclinical and clinical studies suggest that the opioid antagonist naltrexone (NTX) is effective in reducing the abuse liability of amphetamine, raising the question of whether similar positive findings would be obtained for cocaine. The purpose of this study was to evaluate the ability of oral NTX to alter the cardiovascular and subjective effects of D-amphetamine (D-AMPH) and cocaine (COC). Non-treatment-seeking COC users (N=12) completed this 3-week inpatient, randomized, crossover study. Participants received 0, 12.5, or 50 mg oral NTX 60 min before active or placebo stimulant administration during 10 separate laboratory sessions. Oral AMPH (0, 10, and 20 mg; or all placebo) was administered in ascending order within a laboratory session using a 60-min interdose interval. Smoked COC (0, 12.5, 25, and 50 mg; or all placebo) was administered in ascending order within a laboratory session using a 14-min interdose interval. Active COC and AMPH produced dose-related increases in cardiovascular function that were of comparable magnitude. In contrast, COC, but not AMPH, produced dose-related increases in several subjective measures of positive drug effect (eg, high, liking, and willingness to pay for the drug). NTX did not alter the cardiovascular effects of AMPH or COC. NTX also did not alter positive subjective ratings after COC administration, but it did significantly reduce ratings of craving for COC and tobacco during COC sessions. These results show that (1) oral AMPH produces minimal abuse-related subjective responses in COC smokers, and (2) NTX reduces craving for COC and tobacco during COC sessions. Future studies should continue to evaluate NTX as a potential anti-craving medication for COC dependence. PMID:23736314

In order to better prepare future health care professionals for interprofessional cooperation, interprofessional learning sessions for medical students and physiotherapy apprentices were developed at the University Medical Centre Mannheim, Germany. The experience gained from designing, implementing and evaluating these learning sessions is presented and discussed. A total of 265 medical students and 43 physiotherapy apprentices attended five interprofessional learning sessions. Of these, 87-100% responded to closed and open-ended questions on a self-developed questionnaire (24 items). The responses regarding self-reported learning gains, benefit, motivation and satisfaction with the sessions were analyzed separately by professions. The learning sessions were well received by both groups. More than 75% of all participants were of the opinion that they could not have learned the new material in a better way. Significant differences between the medical students and the physiotherapy apprentices were mainly found with regard to perceived learning gains, which physiotherapy apprentices reported as being lower. Positive aspects of interprofessionalism were most often emphasized in the responses to the open-ended questions. Most frequently criticized were organizational aspects and a lack of perceived learning gains. The introduction of interprofessional learning entails great effort in terms of organizational and administrative challenges. However, the project is considered worthwhile because the interprofessional aspects of the learning sessions were indeed valued by the participants. Permanently including and expanding interprofessional learning in the curricula of both professions longitudinally is therefore something to strive for.

Motor sequences can be learned using an incremental approach by starting with a few elements and then adding more as training evolves (e.g., learning a piano piece); conversely, one can use a global approach and practice the whole sequence in every training session (e.g., shifting gears in an automobile). Yet, the neural correlates associated with such learning strategies in motor sequence learning remain largely unexplored to date. Here we used functional magnetic resonance imaging to measure the cerebral activity of individuals executing the same 8-element sequence after they completed a 4-days training regimen (2 sessions each day) following either a global or incremental strategy. A network comprised of striatal and fronto-parietal regions was engaged significantly regardless of the learning strategy, whereas the global training regimen led to additional cerebellar and temporal lobe recruitment. Analysis of chunking/grouping of sequence elements revealed a common prefrontal network in both conditions during the chunk initiation phase, whereas execution of chunk cores led to higher mediotemporal activity (involving the hippocampus) after global than incremental training. The novelty of our results relate to the recruitment of mediotemporal regions conditional of the learning strategy. Thus, the present findings may have clinical implications suggesting that the ability of patients with lesions to the medial temporal lobe to learn and consolidate new motor sequences may benefit from using an incremental strategy.

Decoded fMRI neurofeedback can induce bidirectional confidence changes within single participants.

2017-04-01

Neurofeedback studies using real-time functional magnetic resonance imaging (rt-fMRI) have recently incorporated the multi-voxel pattern decoding approach, allowing for fMRI to serve as a tool to manipulate fine-grained neural activity embedded in voxel patterns. Because of its tremendous potential for clinical applications, certain questions regarding decoded neurofeedback (DecNef) must be addressed. Specifically, can the same participants learn to induce neural patterns in opposite directions in different sessions? If so, how does previous learning affect subsequent induction effectiveness? These questions are critical because neurofeedback effects can last for months, but the short- to mid-term dynamics of such effects are unknown. Here we employed a within-subjects design, where participants underwent two DecNef training sessions to induce behavioural changes of opposing directionality (up or down regulation of perceptual confidence in a visual discrimination task), with the order of training counterbalanced across participants. Behavioral results indicated that the manipulation was strongly influenced by the order and the directionality of neurofeedback training. We applied nonlinear mathematical modeling to parametrize four main consequences of DecNef: main effect of change in confidence, strength of down-regulation of confidence relative to up-regulation, maintenance of learning effects, and anterograde learning interference. Modeling results revealed that DecNef successfully induced bidirectional confidence changes in different sessions within single participants. Furthermore, the effect of up- compared to down-regulation was more prominent, and confidence changes (regardless of the direction) were largely preserved even after a week-long interval. Lastly, the effect of the second session was markedly diminished as compared to the effect of the first session, indicating strong anterograde learning interference. These results are interpreted in the framework of reinforcement learning and provide important implications for its application to basic neuroscience, to occupational and sports training, and to therapy.

Participants in the workshop session were actively engaged in a hands-on, minds-on approach to learning about indicators and evaluation processes. The six hour session was broken down into three two hour sessions. Each session was built upon an instructional model which moved from general understanding to specific IITA application. Examples and practice exercises served to demonstrate tand reinforce the workshop concepts. Each successive session built upon the previous session and addressed the major steps in the evaluation process. The major steps covered in the workshop included: project descriptions, writing goals and objectives for categories, determining indicators and indicator systems for specific projects, and methods and issues of data collection. The workshop served as a baseline upon which the field centers will build during the summer in undertaking a comprehensive examination and evaluation of their existing K-12 education projects.

We investigated the use of cooperative learning groups as an instructional strategy for integrating 2 students with autism into a fourth-grade social studies class. Baseline consisted of 40 min of teacher-led sessions including lecture, questions and discussion with students, and the use of maps. The intervention condition consisted of 10 min of teacher introduction of new material, followed by cooperative learning groups that included tutoring on key words and facts, a team activity, and a whole class wrap-up and review. An ABAB design showed increases for target students and peers for the number of items gained on weekly pretests and posttests, the percentage of academic engagement during sessions, and durations of student interaction during the intervention.

2011-01-01

This pilot study was designed to assess the perceptions of physical therapy (PT) and occupational therapy (OT) students regarding the use of computer-assisted pedagogy and prosection-oriented communications in the laboratory component of a human anatomy course at a comprehensive health sciences university in the southeastern United States. The goal was to determine whether student perceptions changed over the course of a summer session regarding verbal, visual, tactile, and web-based teaching methodologies. Pretest and post-test surveys were distributed online to students who volunteered to participate in the pilot study. Despite the relatively small sample size, statistically significant results indicated that PT and OT students who participated in this study perceived an improved ability to name major anatomical structures from memory, to draw major anatomical structures from memory, and to explain major anatomical relationships from memory. Students differed in their preferred learning styles. This study demonstrates that the combination of small group learning and digital web-based learning seems to increase PT and OT students' confidence in their anatomical knowledge. Further research is needed to determine which forms of integrated instruction lead to improved student performance in the human gross anatomy laboratory.

Collier, Izabela A; Baker, David M

2017-07-01

The purpose of this project was to design and develop a health care communications course built around practice-like simulations and active learning in the first year of a professional pharmacy program. A three-credit health care communications course was divided into one didactic (two hours per week) and three simulation components (one hour per week). The simulation components consisted of one written patient education pamphlet, three group presentations, and three one-on-one patient counseling sessions. This was accomplished by breaking the class of approximately 75 students into eight separate sections, each consisting of 8-10 students and one instructor. Each week four sections were devoted to counseling role-plays: half in the role of pharmacists and half as patients. The other four sections were devoted to hour-long professional group presentations-half in the presenting group and half as audience. The students' performance in the simulated counseling sessions and group presentations has been tracked and analyzed to determine if the simulated exercises had a positive impact on the students' active communications skills. Consistently, over the first four years of the implementation of the course, students' communications skills, as measured by faculty assessments, in both professional group presentations and one-on-one counseling sessions significantly improved. Incorporation of active-learning simulation exercises into a healthcare communications course has a positive impact on the development of students' communications skills. This creates a foundation upon which students can build over the remainder of the professional program and into their future careers. Copyright © 2017 Elsevier Inc. All rights reserved.

Alfaisal University is a new medical school in Riyadh, Kingdom of Saudi Arabia that matriculates eligible students directly from high school and requires them to participate in a hybrid problem-based learning (PBL) curriculum. PBL is a well-established student-centered approach, and the authors have sought to examine if a student-centered, integrated approach to learn human structures leads to positive perceptions of learning outcomes. Ten students were divided into four groups to rotate through wet and dry laboratory stations (integrated resource sessions, IRSs) that engaged them in imaging techniques, embryology, histology, gross anatomy (dissections and prosections), surface anatomy, and self-directed learning questions. All IRSs were primarily directed by students. During two second-semester organ system blocks, forty students responded to a structured questionnaire designed to poll students' perceptions of changes in their knowledge, skills, and attitudes as a result of IRS. The majority (60%) of students felt that the student-centered approach to learning enhanced their medical knowledge. Most students also felt that the IRS approach was advantageous for formulating clear learning objectives (55%) and in preparing for examinations (65%). Despite their positive feelings toward IRS, students did not view this learning approach as an adequate replacement for the knowledge gained from lectures and textbooks. Students' performance on objective structured practical examinations improved significantly for the two curricular blocks that included IRS compared with earlier non-IRS blocks. A student-centered approach to teach human structure in a hybrid PBL curriculum may enhance understanding of the basic sciences in first-year medical students.

Explicit instruction of rules interferes with visuomotor skill transfer.

PubMed

Tanaka, Kanji; Watanabe, Katsumi

2017-06-01

In the present study, we examined the effects of explicit knowledge, obtained through instruction or spontaneous detection, on the transfer of visuomotor sequence learning. In the learning session, participants learned a visuomotor sequence, via trial and error. In the transfer session, the order of the sequence was reversed from that of the learning session. Before the commencement of the transfer session, some participants received explicit instruction regarding the reversal rule (i.e., Instruction group), while the others did not receive any information and were sorted into either an Aware or Unaware group, as assessed by interview conducted after the transfer session. Participants in the Instruction and Aware groups performed with fewer errors than the Unaware group in the transfer session. The participants in the Instruction group showed slower speed than the Aware and Unaware groups in the transfer session, and the sluggishness likely persisted even in late learning. These results suggest that explicit knowledge reduces errors in visuomotor skill transfer, but may interfere with performance speed, particularly when explicit knowledge is provided, as opposed to being spontaneously discovered.

Home-based vs. laboratory-based practical activities in the learning of human physiology: the perception of students.

Different tools have been used to facilitate the teaching and learning process in different areas of knowledge. Practical activities represent a form of teaching in which students not only listen to theoretical concepts but are also able to link theory and practice, and their importance in the biological sciences is notable. Sometimes, however, there is neither the time nor the resources to promote laboratory practices in physiology classes. In this sense, home-based practical activities may be an interesting alternative. Here, different approaches of practical activities were used and students' perceptions of the contributions of home-based practical activities (HBPA) and laboratory-based practical activities (LBPA) for physiology learning were collected. After each approach, the students evaluated the activities through an anonymous questionnaire. A total of 49 students completed the questionnaires, and the results demonstrate that both HBPA and LBPA were considered important contributors to physiology learning but that this contribution was more significant in the case of LBPA (χ 2 = 4.356, P = 0.037).

Using Recreational Drones to Promote STEM Learning

2017-12-01

The popularity of unmanned aerial vehicles (UAVs or drones) as a fun, inexpensive (<$100), and easy to fly "toy" continues to grow yearly. Flying drones can also serve as a great entry point to stimulate curiosity and encourage students to engage in science, technology, engineering, and math (STEM) investigations. Leveraging the popularity of recreational drones, the Education Committee at the Earth System Information Partners (ESIP) has worked with educators, researchers, and data scientists to develop a Drones for STEM initiative to inspire learners to use drones as a platform to collect and analyze local-scale data using lightweight cameras and/or sensors. In 2016, the initiative developed learning activity outlines and piloted the materials at an ESIP-sponsored teacher workshop and National Science Teacher Association sessions. After incorporating feedback from those sessions, ESIP collaborated with the UCAR Center for Science Education to publish finalized activities. Available on the UCAR SciEd website (SciEd.ucar.edu/engineering-activities), the activities encompass skills to measure drone payload, flight height, and velocity. Investigations also encourage the use of repeat photography, comparing images from drones and satellites, and creating 3D structure from motion (SfM) models from overlapping photographs. The site also offers general guidance to develop science projects or science fair investigations using Next Generation Science Standards science and engineering practices. To encourage the use of drones in STEM, UNAVCO and NOAA staff, sponsored by ESIP, led two hands-on workshops this summer; a three half-day workshop at the Earth Educator Rendezvous (EER) and a half-day session during the ESIP Educator Workshop. Participants practiced UAV flying skills, experimented with lightweight sensors, and learned about current drone-enhanced research projects. In small groups, they tested existing activities and designed student-focused investigations. Examples of projects include measuring aeromagnetics, developing 3D topographic models, creating vertical profiles over various land-surfaces at different temporal intervals, and developing a multi-semester drone-focused curriculum. This presentation will elaborate upon the workshops, learning materials, and insights.

Visual areas become less engaged in associative recall following memory stabilization.

Numerous studies have focused on changes in the activity in the hippocampus and higher association areas with consolidation and memory stabilization. Even though perceptual areas are engaged in memory recall, little is known about how memory stabilization is reflected in those areas. Using magnetoencephalography (MEG) we investigated changes in visual areas with memory stabilization. Subjects were trained on associating a face to one of eight locations. The first set of associations ('stabilized') was learned in three sessions distributed over a week. The second set ('labile') was learned in one session just prior to the MEG measurement. In the recall session only the face was presented and subjects had to indicate the correct location using a joystick. The MEG data revealed robust gamma activity during recall, which started in early visual cortex and propagated to higher visual and parietal brain areas. The occipital gamma power was higher for the labile than the stabilized condition (time=0.65-0.9 s). Also the event-related field strength was higher during recall of labile than stabilized associations (time=0.59-1.5 s). We propose that recall of the spatial associations prior to memory stabilization involves a top-down process relying on reconstructing learned representations in visual areas. This process is reflected in gamma band activity consistent with the notion that neuronal synchronization in the gamma band is required for visual representations. More direct synaptic connections are formed with memory stabilization, thus decreasing the dependence on visual areas.

The activity of thalamic nucleus reuniens is critical for memory retrieval, but not essential for the early phase of "off-line" consolidation.

PubMed

Spatial navigation depends on the hippocampal function, but also requires bidirectional interactions between the hippocampus (HPC) and the prefrontal cortex (PFC). The cross-regional communication is typically regulated by critical nodes of a distributed brain network. The thalamic nucleus reuniens (RE) is reciprocally connected to both HPC and PFC and may coordinate the information flow within the HPC-PFC pathway. Here we examined if RE activity contributes to the spatial memory consolidation. Rats were trained to find reward following a complex trajectory on a crossword-like maze. Immediately after each of the five daily learning sessions the RE was reversibly inactivated by local injection of muscimol. The post-training RE inactivation affected neither the spatial task acquisition nor the memory retention, which was tested after a 20-d "forgetting" period. In contrast, the RE inactivation in well-trained rats prior to the maze exposure impaired the task performance without affecting locomotion or appetitive motivation. Our results support the role of the RE in memory retrieval and/or "online" processing of spatial information, but do not provide evidence for its engagement in "off-line" processing, at least within a time window immediately following learning experience. © 2018 Mei et al.; Published by Cold Spring Harbor Laboratory Press.

Objective. To assess the integration of problem-based learning and technology into a self-care course. Design. Problem-based learning (PBL) activities were developed and implemented in place of lectures in a self-care course. Students used technology, such as computer-generated virtual patients and iPads, during the PBL sessions. Assessments. Students’ scores on post-case quizzes were higher than on pre-case quizzes used to assess baseline knowledge. Student satisfaction with problem-based learning and the use of technology in the course remained consistent throughout the semester. Conclusion. Integrating problem-based learning and technology into a self-care course enabled students to become active learners. PMID:23966730

Using Reinforcement Learning to Provide Stable Brain-Machine Interface Control Despite Neural Input Reorganization

2014-01-01

Brain-machine interface (BMI) systems give users direct neural control of robotic, communication, or functional electrical stimulation systems. As BMI systems begin transitioning from laboratory settings into activities of daily living, an important goal is to develop neural decoding algorithms that can be calibrated with a minimal burden on the user, provide stable control for long periods of time, and can be responsive to fluctuations in the decoder’s neural input space (e.g. neurons appearing or being lost amongst electrode recordings). These are significant challenges for static neural decoding algorithms that assume stationary input/output relationships. Here we use an actor-critic reinforcement learning architecture to provide an adaptive BMI controller that can successfully adapt to dramatic neural reorganizations, can maintain its performance over long time periods, and which does not require the user to produce specific kinetic or kinematic activities to calibrate the BMI. Two marmoset monkeys used the Reinforcement Learning BMI (RLBMI) to successfully control a robotic arm during a two-target reaching task. The RLBMI was initialized using random initial conditions, and it quickly learned to control the robot from brain states using only a binary evaluative feedback regarding whether previously chosen robot actions were good or bad. The RLBMI was able to maintain control over the system throughout sessions spanning multiple weeks. Furthermore, the RLBMI was able to quickly adapt and maintain control of the robot despite dramatic perturbations to the neural inputs, including a series of tests in which the neuron input space was deliberately halved or doubled.

2008-01-01

Passive educational techniques (such as lectures) are thought to be less productive than active learning. We examined whether preparing for and participating in a debate would be an effective, active way to learn about a controversial topic. We compared quiz performance in residents who attended a lecture to residents who prepared for/participated in a debate. Twelve residents each participated in one lecture session and one debate session. Learning was evaluated via a quiz. Quizzes were given twice: before the debate/lecture and 1 week after the debate/lecture. Quiz scores were compared using repeated measures analysis of variance, with a p value of < .05 considered significant. A survey evaluating the usefulness of debating was given to all participants. There was a statistically significant difference in the pretest mean quiz score between the debate and lecture groups: 78.3% and 52.5%, respectively (p = .02). Similarly, on posttest quizzes, the average debater scored 85.8%, versus 61.7% for the lecture group (p = .003). Although no one in the debate group scored lower on a follow-up quiz, 3 residents in the lecture group did worse on follow-up. When learning about a controversial topic, residents who prepared for/participated in a debate achieved higher quiz scores and were better at retaining information than those who attended a lecture. When faced with teaching a controversial topic, organizing a debate may be more effective than giving a lecture.

Acquisition of neural learning in cerebellum and cerebral cortex for smooth pursuit eye movements

Li, Jennifer X.; Medina, Javier F.; Frank, Loren M.; Lisberger, Stephen G.

2011-01-01

We have evaluated the emergence of neural learning in the frontal eye fields (FEFSEM) and the floccular complex of the cerebellum while monkeys learned a precisely-timed change in the direction of pursuit eye movement. For each neuron, we measured the time course of changes in neural response across a learning session that comprised at least 100 repetitions of an instructive change in target direction. In both areas, the average population learning curves tracked the behavioral changes with high fidelity, consistent with possible roles in driving learning. However, the learning curves of individual neurons sometimes bore little relation to the smooth, monotonic progression of behavioral learning. In the FEFSEM, neural learning was episodic. For individual neurons, learning appeared at different times during the learning session and sometimes disappeared by the end of the session. Different FEFSEM neurons expressed maximal learning at different times relative to the acquisition of behavioral learning. In the floccular complex, many Purkinje cells acquired learned simple-spike responses according to the same time course as behavioral learning and retained their learned responses throughout the learning session. A minority of Purkinje cells acquired learned responses late in the learning session, after behavioral learning had reached an asymptote. We conclude that learning in single neurons can follow a very different time course from behavioral learning. Both the FEFSEM and the floccular complex contain representations of multiple temporal components of learning, with different neurons contributing to learning at different times during the acquisition of a learned movement.

Nurses who provide case management can improve care practice and outcomes among patients who have type 2 diabetes through appropriate training and systems of care. This study was conducted to improve ambulatory care nurses' perceptions of competency in empowerment-based skills required for diabetes self-management education after participation in a multifaceted educational session that included problem-based learning and simulation. After participation in the multifaceted educational session, nurses (n = 21) perceived that the education provided an excellent opportunity for knowledge uptake and applicability to their respective work settings. The learning strategies provided opportunities for engagement in a safe and relaxed atmosphere. The simulation experience allowed participants to deliberately practice the competencies. These nurses considered this a very effective learning activity. Through the use of problem-based learning and simulation, nurses may be able to more efficiently and effectively develop the necessary skills to provide effective case management of chronic disease.

The hippocampal formation (HF) is implicated in a comparator that detects sensory conflict (mismatch) among convergent inputs. This suggests that new place cells encoding the new configuration with sensory mismatch develop after the HF learns to accept the new configuration as a match. To investigate this issue, HF CA1 place cell activity in rats was analyzed after the adaptation of the rats to the same sensory mismatch condition. The rats were placed on a treadmill on a stage that was translocated in a figure 8-shaped pathway. We recorded HF neuronal activities under three conditions; (1) an initial control session, in which both the stage and the treadmill moved forward, (2) a backward (mismatch) session, in which the stage was translocated backward while the rats locomoted forward on the treadmill, and (3) the second control session. Of the 161 HF neurons, 56 place-differential activities were recorded from the HF CA1 subfield. These place-differential activities were categorized into four types; forward-related, backward-related, both-translocation-related, and session-dependent. Forward-related activities showed predominant spatial firings in the forward sessions, while backward-related activities showed predominant spatial firings in the backward sessions. Both-translocation-related activities showed consistent spatial firings in both the forward and backward conditions. On the other hand, session-dependent activities showed different spatial firings across the sessions. Detailed analyses of the place fields indicated that mean place field sizes were larger in the forward-related, backward-related, and both-translocation-related activities than in the session-dependent activities. Furthermore, firing rate distributions in the place fields were negatively skewed and asymmetric, which is similar to place field changes that occur after repeated experience. These results demonstrate that the HF encodes a naturally impossible new configuration of sensory inputs after adaptation, suggesting that the HF is capable of updating its stored memory to accept a new configuration as a match by repeated experience.

Instrumental conditioning of EEG activity (EEG-IC) is a promising method for improvement and rehabilitation of cognitive functions. However, it has been found that even healthy adults are not always able to learn how to regulate their brain activity during EEG-IC. In the present study, the role of a neurophysiological predictor of EEG-IC learning performance, the resting-state power of sensorimotor rhythm (rs-SMR, 12-15Hz), was investigated. Eyes-open and eyes-closed rs-SMR power was assessed before N=28 healthy adults underwent 10 training sessions of instrumental SMR conditioning (ISC), in which participants should learn to voluntarily increase their SMR power by means of audio-visual feedback. A control group of N=19 participants received gamma (40-43Hz) or sham EEG-IC. N=19 of the ISC participants could be classified as "responders" as they were able to increase SMR power during training sessions, while N=9 participants ("non-responders") were not able to increase SMR power. Rs-SMR power in responders before start of ISC was higher in widespread parieto-occipital areas than in non-responders. A discriminant analysis indicated that eyes-open rs-SMR power in a central brain region specifically predicted later ISC performance, but not an increase of SMR in the control group. Together, these findings indicate that rs-SMR power is a specific and easy-to-measure predictor of later ISC learning performance. The assessment of factors that influence the ability to regulate brain activity is of high relevance, as it could be used to avoid potentially frustrating and expensive EEG-IC training sessions for participants who have a low chance of success.

Aim: In order to better prepare future health care professionals for interprofessional cooperation, interprofessional learning sessions for medical students and physiotherapy apprentices were developed at the University Medical Centre Mannheim, Germany. The experience gained from designing, implementing and evaluating these learning sessions is presented and discussed. Method: A total of 265 medical students and 43 physiotherapy apprentices attended five interprofessional learning sessions. Of these, 87-100% responded to closed and open-ended questions on a self-developed questionnaire (24 items). The responses regarding self-reported learning gains, benefit, motivation and satisfaction with the sessions were analyzed separately by professions. Results: The learning sessions were well received by both groups. More than 75% of all participants were of the opinion that they could not have learned the new material in a better way. Significant differences between the medical students and the physiotherapy apprentices were mainly found with regard to perceived learning gains, which physiotherapy apprentices reported as being lower. Positive aspects of interprofessionalism were most often emphasized in the responses to the open-ended questions. Most frequently criticized were organizational aspects and a lack of perceived learning gains. Conclusion: The introduction of interprofessional learning entails great effort in terms of organizational and administrative challenges. However, the project is considered worthwhile because the interprofessional aspects of the learning sessions were indeed valued by the participants. Permanently including and expanding interprofessional learning in the curricula of both professions longitudinally is therefore something to strive for. PMID:27280142

2007-06-01

There is controversial evidence of the impact of individual learning style on students' performance in computer-aided learning. We assessed the association between the use of multimedia materials, such as video clips, and collaborative communication tools with learning outcome among medical students. One hundred and twenty-one third-year medical students attended a course in medical informatics (0.7 credits) consisting of lectures, small group sessions and eLearning material. The eLearning material contained six learning modules with integrated video clips and collaborative learning tools in WebCT. Learning outcome was measured with a course exam. Approximately two-thirds of students (68.6%) viewed two or more videos. Female students were significantly more active video-watchers. No significant associations were found between video-watching and self-test scores or the time used in eLearning. Video-watchers were more active in WebCT; they loaded more pages and more actively participated in discussion forums. Video-watching was associated with a better course grade. Students who watched video clips were more active in using collaborative eLearning tools and achieved higher course grades.

An amendment to the German medical curriculum in April 2002 will place basic practical skills at the centre of medical training. We report here on the implementation and evaluation of an obligatory, tutor-guided, and integrated skills laboratory concept in the field of internal medicine. To test the effectiveness of a skills laboratory training on OSCE performance a pilot study was carried out. The experimental group, of 77 students, participated in seven sessions of communication training, skills laboratory training, and bedside teaching, each lasting one and a half hours. The control group of 66 students had as many sessions but was only offered bedside-teaching. The evaluation of acceptance of skills' training as well as the related increase in individual competence is on-going (summer term 2004: n = 176 students). The integrated skills laboratory concept was rated at 3.5 (SD = 1.2) on a 5-point scale and was acknowledged as practice-oriented (M = 4.2; SD = 1.0) and relevant for doctors' everyday lives (M = 3.6; SD = 1.1). Increased levels of competence according to individual self-evaluations proved to be highly significant (p<.001), and results of the pilot study showed that the experimental group had a significantly better OSCE performance than the control group (p<.001). This pilot study shows that curriculum changes promoting basic clinical skills are effective and lead to an improved practical education of tomorrow's physicians. The integrated skills laboratory concept is well accepted and leads to a relevant increase in competence in the practice of internal medical. The presented skills laboratory concept in internal medicine is proving to be a viable and efficient learning tool.

Several studies have suggested the existence of cognitive deficits after repeated or high doses of 3,4-methylenedioxymethamphetamine (MDMA) in humans and experimental animals. However, the extent of the impairments observed in learning or memory tasks remains unclear. The objective of this study was to evaluate the effects of different dosing regimens of MDMA on the ability of mice to learn and recall an active avoidance task. Animals were treated with MDMA (0, 1, 3, 10 and 30 mg/kg) under four different experimental conditions, and active avoidance acquisition and recall were evaluated. In experiments 1 and 2, MDMA was administered 1 h before different active avoidance training sessions. In experiments 3 and 4, mice received a repeated treatment with MDMA before or after active avoidance training, respectively. Changes in presynaptic striatal dopamine transporter (DAT) binding sites were evaluated at two different time points in animals receiving a high dose of MDMA (30 mg/kg) or saline twice a day over 4 days. MDMA administered before the active avoidance sessions interfered with the acquisition and the execution of a previously learned task. A repeated treatment with high doses of MDMA administered before training reduced acquisition of active avoidance in mice, while pre-treatment with both high and low doses of MDMA impaired recall of this task. A reduction in DAT binding was observed 4 days but not 23 days after the last MDMA administration. Acute MDMA modifies the acquisition and execution of active avoidance in mice, while repeated pre-treatment with MDMA impairs acquisition and recall of this task.

Leveraging anatomical information to improve transfer learning in brain-computer interfaces

Objective. Brain-computer interfaces (BCIs) represent a technology with the potential to rehabilitate a range of traumatic and degenerative nervous system conditions but require a time-consuming training process to calibrate. An area of BCI research known as transfer learning is aimed at accelerating training by recycling previously recorded training data across sessions or subjects. Training data, however, is typically transferred from one electrode configuration to another without taking individual head anatomy or electrode positioning into account, which may underutilize the recycled data. Approach. We explore transfer learning with the use of source imaging, which estimates neural activity in the cortex. Transferring estimates of cortical activity, in contrast to scalp recordings, provides a way to compensate for variability in electrode positioning and head morphologies across subjects and sessions. Main results. Based on simulated and measured electroencephalography activity, we trained a classifier using data transferred exclusively from other subjects and achieved accuracies that were comparable to or surpassed a benchmark classifier (representative of a real-world BCI). Our results indicate that classification improvements depend on the number of trials transferred and the cortical region of interest. Significance. These findings suggest that cortical source-based transfer learning is a principled method to transfer data that improves BCI classification performance and provides a path to reduce BCI calibration time.

Objective To test an active-learning, empowerment approach to teaching patients about the “diabetes ABCs” (hemoglobin A1C, systolic blood pressure, and low density lipoprotein cholesterol). Methods 84 (97%) diabetic patients who participated in a randomized effectiveness trial of two clinic-based group educational methods and completed a post-intervention assessment. The empowerment arm participated in a group session that incorporated two educational innovations (a conceptual metaphor to foster understanding, and team-based learning methods to foster active learning). The traditional diabetes education arm received a didactic group session focused on self-management and educational materials about the diabetes ABCs. Participants in both arms received individual review of their current ABC values. Results A questionnaire evaluated knowledge, understanding, and recall of the diabetes ABCs was administered three months after enrollment in the study. At three months, participants in the empowerment group demonstrated greater understanding of the diabetes ABCs (P<.0001), greater knowledge of their own values (P<.0001), and greater knowledge of guideline-derived target goals for the ABCs compared with participants in the traditional arm (P<.0001). Conclusion An active-learning, empowerment-based approach applied to diabetes education can lead to greater understanding and knowledge retention. Practice Implications An empowerment approach to education can facilitate informed, activated patients and increase performance of self-management behaviors. PMID:21300516

Introduction: Based on the principles of Pavlovian learning and extinction, cue exposure therapy (CET) involves repeated exposure to substance-associated cues to extinguish conditioned cravings and reduce the likelihood of relapse. The efficacy of CET is predicated on successful extinction, yet the process of extinction in CET trials has rarely been demonstrated. This study explored the extinction process using a cue-reactivity paradigm in smokers undergoing multiple CET sessions as part of a comprehensive smoking cessation treatment. Methods: The sample comprised 76 moderately dependent, treatment-seeking smokers who completed at least 4 CET sessions and 6 counseling sessions. The CET and counseling sessions were scheduled twice weekly, and participants began using transdermal nicotine replacement therapy on their quit day, which occurred prior to initiation of CET. Each CET session consisted of presentation of 140 images on a computer screen, with self-reported craving as the primary measure of cue reactivity. Results: Mixed-model analyses revealed a progressive decline in cue-provoked craving both within and across 6 sessions of CET. Moderator analyses showed that the decline in craving was greatest among those who displayed initial cue reactivity. Conclusions: These data are consistent with the premise that CET can produce extinction of laboratory-based cue-provoked smoking cravings and highlight important individual differences that may influence extinction. Implications for conducting cue exposure research and interventions are discussed. PMID:24078760

2007-06-15

To determine the effectiveness and student acceptance of using a human patient simulation (HPS) training module focused on interdisciplinary teamwork skills. During their second-professional year, all pharmacy students were in enrolled in Principles of Pharmacotherapy 4: Cardiovascular Diseases and Patient Care Lab IV, a problem-based learning course. As part of the patient care laboratory, students participated in a simulated case of an acutely ill patient with a hypertensive emergency. During the simulation, students performed a history and physical examination. They then worked as a team to make treatment recommendations to the nursing and physician staff members. Following the exercise, a facilitated debriefing session was conducted. Students completed satisfaction surveys to assess the quality and effectiveness of the session. Over 98% of students agreed or strongly agreed that they learned material relevant to their current studies. When compared to student lectures, 90% of students felt that they learned clinical patient care better when using a HPS mannequin in simulated patient scenarios. HPS-based learning offers a realistic training experience through which clinical knowledge and interpersonal teamwork skills can be taught. Students enjoy the experience and find it relevant to their future practice. Simulation-based training may teach certain topics better than traditional lecture formats and as such could help to fill gaps in the current pharmacy curriculum.

On the potential for using immersive virtual environments to support laboratory experiment contextualisation

NASA Astrophysics Data System (ADS)

Machet, Tania; Lowe, David; Gütl, Christian

2012-12-01

This paper explores the hypothesis that embedding a laboratory activity into a virtual environment can provide a richer experimental context and hence improve the understanding of the relationship between a theoretical model and the real world, particularly in terms of the model's strengths and weaknesses. While an identified learning objective of laboratories is to support the understanding of the relationship between models and reality, the paper illustrates that this understanding is hindered by inherently limited experiments and that there is scope for improvement. Despite the contextualisation of learning activities having been shown to support learning objectives in many fields, there is traditionally little contextual information presented during laboratory experimentation. The paper argues that the enhancing laboratory activity with contextual information affords an opportunity to improve students' understanding of the relationship between the theoretical model and the experiment (which is effectively a proxy for the complex real world), thereby improving their understanding of the relationship between the model and reality. The authors propose that these improvements can be achieved by setting remote laboratories within context-rich virtual worlds.

The Experiential Learning Initiative is a student-scientist partnership initiated during the doctoral program of the author. Essential to the partnership were the cooperative relationships between the teaching and administrative staffs of Bellwood, IL School District 88 and the Michigan State University Department of Entomology. The use of insects, geophysical visualization activities, and extensive fieldwork by the students served as the foundation for non-traditional learning experiences. The university science partner worked with students in an after-school program several days each month. During these sessions, students were given opportunities to experience science as an on-going process based on personal curiosity and creativity. Through their personal investigations in laboratory, field, and field station situations, the students constructed knowledge of Earth processes and ecological interactions. Each academic year of the partnership was brought to closure with a capstone event that included travel to a major university or working field station for a week of on-site investigation, expanded exposure to practicing scientists, and residential living in a scientific community. All students presented posters about a topic of their own areas of interest at the end of the week and again upon return to their schools. The results of this partnership have included strong gains in both personal confidence among the students and in test scores from standardized state tests.

To implement and evaluate the use of a situated-learning experience to prepare second-year pharmacy students to conduct medication history interviews in preparation for introductory pharmacy practice experiences (IPPE) at ambulatory clinic sites. Second-year doctor of pharmacy (PharmD) students (n=200) used the Medication Mysteries Infinite Case Tool, a game-like educational tool in which groups of 3 students assumed the roles of pharmacist, patient, and observer and rolled a die and drew cards to determine the drugs, patient personality, medication problems, and other variables that guided a medication history taking session. After the laboratory session, faculty members assessed students' medication history-taking skills. One hundred sixteen (58%) and 78 (39%) of 200 students achieved excellence or competence, respectively, on the final assessment. Two weeks after the assessment, 53 of 200 (26.5%) students completed a survey instrument. The respondents indicated that their self-confidence in conducting medical history taking significantly improved following completion of the learning experience. Using the Medication Mysteries Infinite Case Tool increased students' confidence and skills in conducting medication history taking prior to their clinical IPPE experience.

Cardiopulmonary resuscitation (CPR) is a first aid key survival technique used to stimulate breathing and keep blood flowing to the heart. Its effective administration can significantly increase the chances of survival for victims of cardiac arrest. LISSA is a serious game designed to complement CPR teaching and also to refresh CPR skills in an enjoyable way. The game presents an emergency situation in a 3D virtual environment and the player has to save the victim applying the CPR actions. In this paper, we describe LISSA and its evaluation in a population composed of 109 nursing undergraduate students enrolled in the Nursing degree of our university. To evaluate LISSA we performed a randomized controlled trial that compares the classical teaching methodology, composed of self-directed learning for theory plus laboratory sessions with a mannequin for practice, with the one that uses LISSA after self-directed learning for theory and before laboratory sessions with a mannequin. From our evaluation we observed that students using LISSA (Group 2 and 3) gave significantly better learning acquisition scores than those following traditional classes (Group 1). To evaluate the differences between students of these groups we performed a paired samples t-test between Group 1 and 2 (μ1=35, 67, μ2=47, 50 and p<0.05) and between students of Group 1 and 3 (μ1=35, 67, μ3=50, 58 and p<0.05). From these tests we observed that there are significant differences in both cases. We also evaluated student performance of main steps of CPR protocol. Students that use LISSA performed better than the ones that did not use it. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Active learning, including the promotion of student interactivity in lectures, has been found to improve student engagement and performance in university science classes. This letter describes the use of Pearson's Learning Catalytics to run regular, formatively assessed problem-solving sessions as part of the semiflipped redesign of an introductory level university bioscience course. Students found the problem-solving sessions more engaging than a traditional lecture, and felt that they were receiving better feedback on their progress in the course. Their participation in the problem-solving sessions was strongly associated with their performance in the course's summative assessments, making it possible to identify and assist probable poor performers early in the course. Other measures of student engagement with the course were not improved, and neither were their average exam grades when compared with their grades in a course which had not been redesigned. Possible reasons for this are discussed. © FEMS 2017. All rights reserved. For permissions, please e-mail: journals.permissions@oup.com.

While the subject of learning has attracted immense interest from both behavioral and neural scientists, only relatively few investigators have observed single-neuron activity while animals are acquiring an operantly conditioned response, or when that response is extinguished. But even in these cases, observation periods usually encompass only a single stage of learning, i.e. acquisition or extinction, but not both (exceptions include protocols employing reversal learning; see Bingman et al.(1) for an example). However, acquisition and extinction entail different learning mechanisms and are therefore expected to be accompanied by different types and/or loci of neural plasticity. Accordingly, we developed a behavioral paradigm which institutes three stages of learning in a single behavioral session and which is well suited for the simultaneous recording of single neurons' action potentials. Animals are trained on a single-interval forced choice task which requires mapping each of two possible choice responses to the presentation of different novel visual stimuli (acquisition). After having reached a predefined performance criterion, one of the two choice responses is no longer reinforced (extinction). Following a certain decrement in performance level, correct responses are reinforced again (reacquisition). By using a new set of stimuli in every session, animals can undergo the acquisition-extinction-reacquisition process repeatedly. Because all three stages of learning occur in a single behavioral session, the paradigm is ideal for the simultaneous observation of the spiking output of multiple single neurons. We use pigeons as model systems, but the task can easily be adapted to any other species capable of conditioned discrimination learning.

In this paper, we explore middle school science teachers' learning of inquiry-based instructional strategies through reflection on practice teaching sessions during a summer enrichment program with middle level students. The reflection sessions were part of a larger year-long inquiry professional development program in which teachers learned science content and inquiry pedagogy. The program included a 2-week summer institute in which teachers participated in science content sessions, practice teaching to middle level students, and small group-facilitated reflection sessions on their teaching. For this study, data collection focused on teachers' recorded dialogue during the facilitator - run reflection sessions, the teachers' daily written reflections, a final written reflection, and a written reflection on a videotaped teaching session. We investigated the teachers' reflection levels and the themes teachers focused on during their reflection sessions. Teachers were found to reflect at various reflection levels, from simple description to a more sophisticated focus on how to improve student learning. Recurrent themes point to the importance of providing situated learning environments, such as the practice teaching with immediate reflection for teachers to have time to practice new instructional strategies and gain insight from peers and science educators on how to handle student learning issues.

Extinguishing abnormally strengthened learned responses to cues associated with drugs of abuse remains a key tactic for alleviating addiction. To assist in developing pharmacotherapies to augment exposure therapy for relapse prevention, investigation into neurobiological underpinnings of drug-cue extinction learning is needed. We used regional analyses of c-Fos and GluR2 protein expression to delineate neural activity and plasticity that may be associated with cocaine-cue extinction learning. Rats were trained to self-administer cocaine paired with a light cue, and later underwent a single 2h extinction session for which cocaine was withheld but response-contingent cues were presented (cocaine-cue extinction). Control groups consisted of rats yoked to animals self-administering cocaine and receiving saline non-contingently followed by an extinction session, or rats trained to self-administer cocaine followed by a no-extinction session for which levers were retracted, and cocaine and cues were withheld. Among 11 brain sites examined, extinction training increased c-Fos expression in basolateral amygdala and prelimbic prefrontal cortex of cocaine-cue extinguished rats relative to both control conditions. In dorsal subiculum and infralimbic prefrontal cortex, extinction training increased c-Fos expression in both cocaine-cue and saline-cue extinguished rats relative to the no-extinction control condition. GluR2 protein expression was not altered in any site examined after extinction or control training. Findings suggest that basolateral amygdala and prelimbic prefrontal cortex neurons are activated during acquisition of cocaine-cue extinction learning, a process that is independent of changes in GluR2 abundance. Other sites are implicated in processing the significance of cues that are present early in extinction training. Copyright © 2012 Elsevier B.V. All rights reserved.

Optimisation of simulated team training through the application of learning theories: a debate for a conceptual framework.

PubMed

Stocker, Martin; Burmester, Margarita; Allen, Meredith

2014-04-03

As a conceptual review, this paper will debate relevant learning theories to inform the development, design and delivery of an effective educational programme for simulated team training relevant to health professionals. Kolb's experiential learning theory is used as the main conceptual framework to define the sequence of activities. Dewey's theory of reflective thought and action, Jarvis modification of Kolb's learning cycle and Schön's reflection-on-action serve as a model to design scenarios for optimal concrete experience and debriefing for challenging participants' beliefs and habits. Bandura's theory of self-efficacy and newer socio-cultural learning models outline that for efficient team training, it is mandatory to introduce the social-cultural context of a team. The ideal simulated team training programme needs a scenario for concrete experience, followed by a debriefing with a critical reflexive observation and abstract conceptualisation phase, and ending with a second scenario for active experimentation. Let them re-experiment to optimise the effect of a simulated training session. Challenge them to the edge: The scenario needs to challenge participants to generate failures and feelings of inadequacy to drive and motivate team members to critical reflect and learn. Not experience itself but the inadequacy and contradictions of habitual experience serve as basis for reflection. Facilitate critical reflection: Facilitators and group members must guide and motivate individual participants through the debriefing session, inciting and empowering learners to challenge their own beliefs and habits. To do this, learners need to feel psychological safe. Let the group talk and critical explore. Motivate with reality and context: Training with multidisciplinary team members, with different levels of expertise, acting in their usual environment (in-situ simulation) on physiological variables is mandatory to introduce cultural context and social conditions to the learning experience. Embedding in situ team training sessions into a teaching programme to enable repeated training and to assess regularly team performance is mandatory for a cultural change of sustained improvement of team performance and patient safety.

The present study aimed to investigate whether chimpanzees (Pan troglodytes) could learn a transverse pattern by being trained in the rules of the rock-paper-scissors game in which "paper" beats "rock," "rock" beats "scissors," and "scissors" beats "paper." Additionally, this study compared the learning processes between chimpanzees and children. Seven chimpanzees were tested using a computer-controlled task. They were trained to choose the stronger of two options according to the game rules. The chimpanzees first engaged in the paper-rock sessions until they reached the learning criterion. Subsequently, they engaged in the rock-scissors and scissors-paper sessions, before progressing to sessions with all three pairs mixed. Five of the seven chimpanzees completed training after a mean of 307 sessions, which indicates that they learned the circular pattern. The chimpanzees required more scissors-paper sessions (14.29 ± 6.89), the third learnt pair, than paper-rock (1.71 ± 0.18) and rock-scissors (3.14 ± 0.70) sessions, suggesting they had difficulty finalizing the circularity. The chimpanzees then received generalization tests using new stimuli, which they learned quickly. A similar procedure was performed with children (35-71 months, n = 38) who needed the same number of trials for all three pairs during single-paired sessions. Their accuracy during the mixed-pair sessions improved with age and was better than chance from 50 months of age, which indicates that the ability to solve the transverse patterning problem might develop at around 4 years of age. The present findings show that chimpanzees were able to learn the task but had difficulties with circularity, whereas children learned the task more easily and developed the relevant ability at approximately 4 years of age. Furthermore, the chimpanzees' performance during the mixed-pair sessions was similar to that of 4-year-old children during the corresponding stage of training.

Effects of learning duration on implicit transfer.

Implicit learning and transfer in sequence acquisition play important roles in daily life. Several previous studies have found that even when participants are not aware that a transfer sequence has been transformed from the learning sequence, they are able to perform the transfer sequence faster and more accurately; this suggests implicit transfer of visuomotor sequences. Here, we investigated whether implicit transfer could be modulated by the number of trials completed in a learning session. Participants learned a sequence through trial and error, known as the m × n task (Hikosaka et al. in J Neurophysiol 74:1652-1661, 1995). In the learning session, participants were required to successfully perform the same sequence 4, 12, 16, or 20 times. In the transfer session, participants then learned one of two other sequences: one where the button configuration Vertically Mirrored the learning sequence, or a randomly generated sequence. Our results show that even when participants did not notice the alternation rule (i.e., vertical mirroring), their total working time was less and their total number of errors was lower in the transfer session compared with those who performed a Random sequence, irrespective of the number of trials completed in the learning session. This result suggests that implicit transfer likely occurs even over a shorter learning duration.

The aim of the current investigation was to examine speech motor sequence learning in neurologically healthy younger adults, neurologically healthy older adults, and individuals with Parkinson disease (PD) over a 2-day period. A sequential nonword repetition task was used to examine learning over 2 days. Participants practiced a sequence of 6 monosyllabic nonwords that was retested following nighttime sleep. The speed and accuracy of the nonword sequence were measured, and learning was inferred by examining performance within and between sessions. Though all groups exhibited comparable improvements of the nonword sequence performance during the initial session, between-session retention of the nonword sequence differed between groups. Younger adult controls exhibited offline gains, characterized by an increase in the speed and accuracy of nonword sequence performance across sessions, whereas older adults exhibited stable between-session performance. Individuals with PD exhibited offline losses, marked by an increase in sequence duration between sessions. The current results demonstrate that both PD and normal aging affect retention of speech motor learning. Furthermore, these data suggest that basal ganglia dysfunction associated with PD may affect the later stages of speech motor learning. Findings from the current investigation are discussed in relation to studies examining consolidation of nonspeech motor learning.

How learning might strengthen existing visual object representations in human object-selective cortex.

Visual object perception is an important function in primates which can be fine-tuned by experience, even in adults. Which factors determine the regions and the neurons that are modified by learning is still unclear. Recently, it was proposed that the exact cortical focus and distribution of learning effects might depend upon the pre-learning mapping of relevant functional properties and how this mapping determines the informativeness of neural units for the stimuli and the task to be learned. From this hypothesis we would expect that visual experience would strengthen the pre-learning distributed functional map of the relevant distinctive object properties. Here we present a first test of this prediction in twelve human subjects who were trained in object categorization and differentiation, preceded and followed by a functional magnetic resonance imaging session. Specifically, training increased the distributed multi-voxel pattern information for trained object distinctions in object-selective cortex, resulting in a generalization from pre-training multi-voxel activity patterns to after-training activity patterns. Simulations show that the increased selectivity combined with the inter-session generalization is consistent with a training-induced strengthening of a pre-existing selectivity map. No training-related neural changes were detected in other regions. In sum, training to categorize or individuate objects strengthened pre-existing representations in human object-selective cortex, providing a first indication that the neuroanatomical distribution of learning effects depends upon the pre-learning mapping of visual object properties.

Cardinale, Jean A

2011-01-01

Longer term research activities that may be incorporated in undergraduate courses are a powerful tool for promoting student interest and learning, developing cognitive process skills, and allowing undergraduates to experience real research activities in which they may not otherwise have the opportunity to participate. The challenge to doing so in lower-level courses is that students may have not fully grasped the scientific concepts needed to undertake such research endeavors, and that they may be discouraged if activities are perceived to be too challenging. The paper describes how a bacterial protein:protein interaction detection system was adapted and incorporated into the laboratory component of a sophomore-level Molecular Cell Biology course. The project was designed to address multiple learning objectives connecting course content to the laboratory activities, as well as teach basic molecular biology laboratory skills and procedures in the context of a primary research activity. Pre- and posttesting and student surveys both suggest that the laboratory curriculum resulted in significant learning gains, as well as being well received and valued by the students.

Project-based learning (PjBL) has been shown to improve students' performance and satisfaction with their coursework, particularly in science and engineering courses. Specific aspects of PjBL that contribute to this improvement are student autonomy, course scaffolding, and instructor support. This study investigates two PjBL courses required for engineering majors at a small technical school, Introductory Mechanics Laboratory and Introductory Engineering Design. The three data sources used in this work are classroom observations (one laboratory and four design sessions) and semi-structured in-depth interviews with twelve students and six faculty. Grounded theory approach is used in a two-step fashion by (1) analyzing each data set individually and (2) performing full triangulation of all three data sets. In this talk, we demonstrate the relationship between faculty intentions and student perceptions regarding the three PjBL aspects -- student autonomy, course scaffolding, and instructor support -- within the context of these two courses. We further discuss implications for the course design and professional development of faculty.

The aim of the pilot study was to design an innovative model of leadership development, Leadership Laboratory (LL), grounded in the lived experiences and peer best practices of 43 cross-disciplinary nurse managers. The Institute of Medicine/Robert Wood Johnson Foundation study, The Future of Nursing, reinforces the need to prepare nurses for leadership positions. A 1-year participatory action research study was designed to develop 3 LLs involving nurse managers as participants, co-creators, and evaluators of the unique learning format. Analysis of qualitative and quantitative data revealed consistent and significantly positive results in leadership skill areas in all 3 LLs. Participants identified elements that distinguished LLs from traditional seminars and trainings sessions, including opportunities to gain from peer-to peer consultation, strategies, and support. Participants in the 1-year pilot demonstrated significant learning based on postsession and postproject assessments of the LLs. Data also described the unique attributes of a peer-driven approach to leadership development.

A molecular genetic lab to generate inclusive and exclusive forensic evidence: two suspects, a victim, and a bloodstained T-shirt.

Molecular genetic laboratory exercises can be ineffective due the student's lack of connection to the complex and sequential protocols. In this inquiry-based molecular genetic laboratory exercise, we harness students' fascination with human forensics and provide a real-life scenario using biomolecular techniques to identify "whose blood is on the t-shirt." We use fish blood to create realistic blood stains on clothing and challenge the students to use DNA analyses to clear or implicate suspects. Safety concerns are minimized through the use of fish blood, while maximizing both realism and the likelihood of student success due to fishes' nucleated red blood cells. The goal in designing this laboratory exercise was to create a feasible protocol for large (over 300 students) second year university courses. During two 3 hour laboratory sessions, students learn and apply clean/sterile technique, DNA extraction, polymerase chain reaction, restriction fragment length polymorphisms, and agarose gel electrophoresis. The students also learn to interpret the resulting gel bands in terms of inclusive or exclusive evidence. Students have consistently ranked this lab as their favorite of five taken as part of a second year Genetics course.

A novel cognitive palatability assessment protocol for dogs.

PubMed

Araujo, J A; Milgram, N W

2004-07-01

Assessment of canine palatability is important for both the pet food and pharmaceutical industries; however, the current palatability assessment protocols are limited in their utility. The most common technique, the two-pan test, does not control for the satiating effects of food and may not be useful for long-term palatability analysis because nutritional or caloric characteristics of the diets may interfere with the results. Furthermore, the large quantities of foods consumed may be detrimental to the health of animals that do not self-limit their food intake. The purpose of this study was to determine whether a cognitive protocol could be used to determine food palatability in dogs. Five beagle dogs were trained on a three-choice object-discrimination learning task. After establishing object preferences, the preferred object was associated with no reward, a second object was associated with the dog's normal laboratory diet (Purina Agribrands Canine Lab Chow No. 5006; Agribrands Purina Canada, Inc., Woodstock, ON, Canada), and the third object was associated with a commercial (Hill's P/D; Hill's Pet Nutrition Inc., Topeka, KS) diet. In the discrimination-training phase, dogs were trained until they learned to avoid the no-reward object. They were subsequently given an additional 20 test sessions, which were used to determine food preference. In the reversal phase, which involved reversal learning, the object-food associations were modified, such that the object that was previously associated with Hill's P/D diet was now associated with the normal laboratory diet and vice versa. Once the dogs learned to avoid the no-reward object, they were tested for an additional 20 sessions. All subjects learned to avoid the no-reward object during the initial learning, and the number of choices to the object associated with the Hill's P/D diet was greater than the number of choices to the objects associated with the dry laboratory diet (P < 0.05) and no reward (P < 0.05), indicating a strong preference for the Hill's P/D diet. The object preferences were reversed in only three of five dogs when the food-choice associations were reversed, although the two phases did not differ significantly from one another. The protocol in the present study provides a robust measure of food palatability and circumvents many of the limitations associated with other palatability assessment techniques. The present protocol should be useful as a replacement or adjunct to other tests of palatability, but requires further validation by comparing the assessment of more similar and novel foods directly with other palatability tests.

Effectiveness of a computer-based tutorial for teaching how to make a blood smear.

Computer-aided instruction (CAI) was developed to teach veterinary students how to make blood smears. This instruction was intended to replace the traditional instructional method in order to promote efficient use of faculty resources while maintaining learning outcomes and student satisfaction. The purpose of this study was to evaluate the effect of a computer-aided blood smear tutorial on 1) instructor's teaching time, 2) students' ability to make blood smears, and 3) students' ability to recognize smear quality. Three laboratory sessions for senior veterinary students were taught using traditional methods (control group) and 4 sessions were taught using the CAI tutorial (experimental group). Students in the control group received a short demonstration and lecture by the instructor at the beginning of the laboratory and then practiced making blood smears. Students in the experimental group received their instruction through the self-paced, multimedia tutorial on a laptop computer and then practiced making blood smears. Data was collected from observation, interview, survey questionnaires, and smear evaluation by students and experts using a scoring rubric. Students using the CAI made better smears and were better able to recognize smear quality. The average time the instructor spent in the room was not significantly different between groups, but the quality of the instructor time was improved with the experimental instruction. The tutorial implementation effectively provided students and instructors with a teaching and learning experience superior to the traditional method of instruction. Using CAI is a viable method of teaching students to make blood smears.

Current teaching methods in graduate and postgraduate training often include frontal presentations. Especially in ultrasound education not only knowledge but also sensomotory and visual skills need to be taught. This requires new learning methods. This study examined which types of teaching methods are preferred by participants in ultrasound training courses before, during and after the course by analyzing a blended learning concept. It also investigated how much time trainees are willing to spend on such activities. A survey was conducted at the end of a certified ultrasound training course. Participants were asked to complete a questionnaire based on a visual analogue scale (VAS) in which three categories were defined: category (1) vote for acceptance with a two thirds majority (VAS 67-100%), category (2) simple acceptance (50-67%) and category (3) rejection (< 50%). A total of 176 trainees participated in this survey. Participants preferred an e-learning program with interactive elements, short presentations (less than 20 min), incorporating interaction with the audience, hands-on sessions in small groups, an alternation between presentations and hands-on-sessions, live demonstrations and quizzes. For post-course learning, interactive and media-assisted approaches were preferred, such as e-learning, films of the presentations and the possibility to stay in contact with instructors in order to discuss the results. Participants also voted for maintaining a logbook for documentation of results. The results of this study indicate the need for interactive learning concepts and blended learning activities. Directors of ultrasound courses may consider these aspects and are encouraged to develop sustainable learning pathways.

Role of clinical tutors in volunteering work camps.

The Università Campus Bio-Medico (Italy) promotes a summer volunteering work camp (Workcamp Perù) as a social activity for medical and non-medical students. Some junior doctors participate as 'clinical tutors', together with tutors from other professions; all clinical tutors have some teaching experience in our teaching hospital. The campsite is located in the South of Peru in the Cañete Valley, an area characterised by extreme poverty and a severe lack of infrastructure. During the five Workcamp Perù trips that have been organised so far, health science students have carried out many activities for disease prevention and health education, and bio-medical engineering students have organised sessions on the safety of electrical installations, for accident prevention. We observed that in this setting tutorial activity is fundamental, because it not only offers students an opportunity to learn but also encourages them to react in a more personal and reflective manner to various stressful situations, which often occur in the work camp. The professional competence of the tutor plays an important role before the work camp, in defining the learning objectives for the students and involving them in training sessions held prior to the work camp. Also, during the camp, tutors work with students and also direct the daily briefing and debriefing sessions that are the most important learning activity. For medical tutors involved in the work camp the volunteering experience is a challenge for developing their specific professional and teaching skills, but it also provides an enriching experience in both professional and personal terms. We consider these work camps to be a useful experience in the training of our clinical tutors. © 2014 John Wiley & Sons Ltd.

Bedside teaching with evidence-based practice elements, supported by e-learning activities, can play an important role in modern medical education. Teachers have to incorporate evidence from the medical literature to increase student motivation and interactivity. An integral part of the medical curricula at Palacky University Olomouc (Czech Republic) are real paediatric scenarios supplemented with a review of current literature to enhance evidence-based bedside teaching & learning. Searching for evidence is taught through librarian-guided interactive hands-on sessions and/or web-based tutorials followed by clinical case presentations and feedback. Innovated EBM paediatric clerkship demonstrated students' preferences towards web-based interactive bedside teaching & learning. In two academic years (2007/2008, 2008/2009), learning-focused feedback from 106 and 131 students, resp. was obtained about their attitudes towards evidence-based bedside teaching. The assessment included among others the overall level of instruction, quality of practical evidence-based training, teacher willingness and impact of instruction on increased interest in the specialty. There was some criticism about excessive workload. A parallel survey was carried out on the perceived values of different forms of information skills training (i.e. demonstration, online tutorials, and librarian-guided interactive search sessions) and post-training self-reported level of search skills. The new teaching/learning paediatric portfolio is a challenge for further activities, including effective knowledge translation, continuing medical & professional development of teachers, and didactic, clinically integrated teaching approaches.

Self-instructional "virtual pathology" laboratories using web-based technology enhance medical school teaching of pathology.

Second-year medical students have traditionally been taught pulmonary pathophysiology at the University of California-Los Angeles (UCLA) School of Medicine using lectures, discussion groups, and laboratory sessions. Since 1998, the laboratory sessions have been replaced by 4 interactive, self-instructional sessions using web-based technology and case-based instruction. This article addresses nature of transformation that occurred from within the course in response to the infusion of new technologies. The vast majority of the course content has been digitized and incorporated into the website of the Pathophysiology of Disease course. The teaching histological slides have been photographed digitally and organized into "cases" with clinical information, digital images and text, and audio descriptions. The students study the materials from these cases at their own pace in 2 "virtual pathology" laboratory, with a few instructors supervising the on-site sessions. The students discuss additional cases available on the website in 2 other laboratory sessions supervised by a pulmonologist and a pathologist. Marked improvement in student participation and satisfaction was seen with the use of web-based instruction. Attendance at laboratory sessions, where the students had previously been required to bring their own microscopes to study histological slides at their own pace, increased from approximately 30% to 40% of the class in previous years to almost 100%. Satisfaction surveys showed progressive improvement over the past 4 years, as various suggestions were implemented. The value of web-based instruction of pathology at the UCLA School of Medicine is discussed.

2012-08-01

Lack of published studies on students' practice behaviour of physical examination skills outside timetabled training sessions inspired this study into what activities medical students undertake to improve their skills and factors influencing this. Six focus groups of a total of 52 students from Years 1-3 using a pre-established interview guide. Interviews were recorded, transcribed and analyzed using qualitative methods. The interview guide was based on questionnaire results; overall response rate for Years 1-3 was 90% (n = 875). Students report a variety of activities to improve their physical examination skills. On average, students devote 20% of self-study time to skill training with Year 1 students practising significantly more than Year 3 students. Practice patterns shift from just-in-time learning to a longitudinal selfdirected approach. Factors influencing this change are assessment methods and simulated/real patients. Learning resources used include textbooks, examination guidelines, scientific articles, the Internet, videos/DVDs and scoring forms from previous OSCEs. Practising skills on fellow students happens at university rooms or at home. Also family and friends were mentioned to help. Simulated/real patients stimulated students to practise of physical examination skills, initially causing confusion and anxiety about skill performance but leading to increased feelings of competence. Difficult or enjoyable skills stimulate students to practise. The strategies students adopt to master physical examination skills outside timetabled training sessions are self-directed. OSCE assessment does have influence, but learning takes place also when there is no upcoming assessment. Simulated and real patients provide strong incentives to work on skills. Early patient contacts make students feel more prepared for clinical practice.

The hypothesis for the research described in this article was that viewing an interactive two-dimensional (2D) or three-dimensional (3D) stereoscopic pre-laboratory video would improve efficiency and learning in the laboratory. A first-year DVM class was divided into 21 dissection teams of four students each. Primary variables were method of preparation (2D, 3D, or laboratory manual) and dissection region (thorax, abdomen, or pelvis). Teams were randomly assigned to a group (A, B, or C) in a crossover design experiment so that all students experienced each of the modes of preparation, but with different regions of the canine anatomy. All students were instructed to study normal course materials and the laboratory manual, the Guide, before coming to the laboratory session and to use them during the actual dissection as usual. Video groups were given a DVD with an interactive 10-12 minute video to view for the first 30 minutes of the laboratory session, while non-video groups were instructed to review the Guide. All groups were allowed 45 minutes to dissect the assigned section and find a list of assigned structures, after which all groups took a post-dissection quiz and attitudinal survey. The 2D groups performed better than the Guide groups (p=.028) on the post-dissection quiz, despite the fact that only a minority of the 2D-group students studied the Guide as instructed. There was no significant difference (p>.05) between 2D and 3D groups on the post-dissection quiz. Students preferred videos over the Guide.

Invention activities as preparation for learning laboratory data handling skills

Day, James

2012-10-01

Undergraduate physics laboratories are often driven by a mix of goals, and usually enough of them to cause cognitive overload for the student. Our recent findings align well with studies indicating that students often exit a physics lab without having properly learned how to handle real data. The value of having students explore the underlying structure of a problem before being able to solve it has been shown as an effective way to ready students for learning. Borrowing on findings from the fields of education and cognitive psychology, we use ``invention activities'' to precede direct instruction and bolster learning. In this talk I will show some of what we have learned about students' data handling skills, explain how an invention activity works, and share some observations of successful transfer.

Active learning in the lecture theatre using 3D printed objects.

The ability to conceptualize 3D shapes is central to understanding biological processes. The concept that the structure of a biological molecule leads to function is a core principle of the biochemical field. Visualisation of biological molecules often involves vocal explanations or the use of two dimensional slides and video presentations. A deeper understanding of these molecules can however be obtained by the handling of objects. 3D printed biological molecules can be used as active learning tools to stimulate engagement in large group lectures. These models can be used to build upon initial core knowledge which can be delivered in either a flipped form or a more didactic manner. Within the teaching session the students are able to learn by handling, rotating and viewing the objects to gain an appreciation, for example, of an enzyme's active site or the difference between the major and minor groove of DNA. Models and other artefacts can be handled in small groups within a lecture theatre and act as a focal point to generate conversation. Through the approach presented here core knowledge is first established and then supplemented with high level problem solving through a "Think-Pair-Share" cooperative learning strategy. The teaching delivery was adjusted based around experiential learning activities by moving the object from mental cognition and into the physical environment. This approach led to students being able to better visualise biological molecules and a positive engagement in the lecture. The use of objects in teaching allows the lecturer to create interactive sessions that both challenge and enable the student.

2016-01-01

The purpose of this study was to compare student perceptions regarding two, small group learning approaches to compressed (46.5 prosection-based laboratory hours), integrated anatomy education at the University of Ottawa medical program. In the facilitated active learning (FAL) approach, tutors engage students and are expected to enable and balance both active learning and progression through laboratory objectives. In contrast, the emphasized independent learning (EIL) approach stresses elements from the "flipped classroom" educational model: prelaboratory preparation, independent laboratory learning, and limited tutor involvement. Quantitative (Likert-style questions) and qualitative data (independent thematic analysis of open-ended commentary) from a survey of students who had completed the preclerkship curriculum identified strengths from the EIL (promoting student collaboration and communication) and FAL (successful progression through objectives) approaches. However, EIL led to student frustration related to a lack of direction and impaired completion of objectives, whereas active learning opportunities in FAL were highly variable and dependent on tutor teaching style. A "hidden curriculum" was also identified, where students (particularly EIL and clerkship students) commonly compared their compressed anatomy education or their anatomy learning environment with other approaches. Finally, while both groups highly regarded the efficiency of prosection-based learning and expressed value for cadaveric-based learning, student commentary noted that the lack of grade value dedicated to anatomy assessment limited student accountability. This study revealed critical insights into small group learning in compressed anatomy education, including the need to balance student active learning opportunities with appropriate direction and feedback (including assessment). © 2015 American Association of Anatomists.

We have applied an active methodology to pre-service teacher training courses and to active teacher workshops on Optics. As a practical resource, a set of demonstrations has been used to learn how to perform classroom demonstrations. The set includes experiments about polarization and birefringence, optical information transmission, diffraction, fluorescence or scattering. It had been prepared for Science popularization activities and has been employed in several settings with a variety of audiences. In the teacher training sessions, simple but clarifying experiments have been performed by all the participants. Moreover, in these workshops, devices or basic set-ups, like the ones included in our demonstration set, have been built. The practical approach has allowed the enthusiastic sharing of teaching and learning experiences among the workshop participants. We believe that such an active orientation in teacher training courses promotes the active and collaborative teaching and learning of Optics in different levels of Education.

Rethinking the lecture: the application of problem based learning methods to atypical contexts.

PubMed

Rogal, Sonya M M; Snider, Paul D

2008-05-01

Problem based learning is a teaching and learning strategy that uses a problematic stimulus as a means of motivating and directing students to develop and acquire knowledge. Problem based learning is a strategy that is typically used with small groups attending a series of sessions. This article describes the principles of problem based learning and its application in atypical contexts; large groups attending discrete, stand-alone sessions. The principles of problem based learning are based on Socratic teaching, constructivism and group facilitation. To demonstrate the application of problem based learning in an atypical setting, this article focuses on the graduate nurse intake from a teaching hospital. The groups are relatively large and meet for single day sessions. The modified applications of problem based learning to meet the needs of atypical groups are described. This article contains a step by step guide of constructing a problem based learning package for large, single session groups. Nurse educators facing similar groups will find they can modify problem based learning to suit their teaching context.

In order to develop an e-learning system that promotes self-learning, lectures and basic operations in laboratory practice of chemistry were recorded and edited on DVD media, consisting of 8 streaming videos as learning materials. Twenty-six students wanted to watch the DVD, and answered the following questions after they had watched it: "Do you think the video would serve to encourage you to study independently in the laboratory practice?" Almost all students (95%) approved of its usefulness, and more than 60% of them watched the videos repeatedly in order to acquire deeper knowledge and skill of the experimental operations. More than 60% answered that the demonstration-experiment should be continued in the laboratory practice, in spite of distribution of the DVD media.

Does Replacing Live Demonstration With Instructional Videos Improve Student Satisfaction and Osteopathic Manipulative Treatment Examination Performance?

PubMed

Seals, Ryan; Gustowski, Sharon M; Kominski, Carol; Li, Feiming

2016-11-01

Instructional videos for osteopathic manipulative treatment (OMT) are a potentially valuable resource for novice learners. To evaluate student experiences and the effectiveness of instructional videos in lieu of live faculty demonstration in a second-year osteopathic manipulative medicine course. Faculty created and produced written instructions and videos for selected Still and facilitated positional release techniques. These materials incorporated curricular design principles and psychomotor skills development strategies. During a second-year OMT skills laboratory session, students used the videos as the primary source for technique demonstration and instruction. Table trainers monitored and assisted students per their request or if errors were observed. Students completed surveys regarding their previous experiences in the OMT skills laboratory sessions (presession survey) and the video-based instructional one (postsession survey). One month after the survey, students were also asked to complete a postexamination survey. Student scores on the skills competency examination were compared with scores from the previous year. Of the 230 students, 162 (70%), 135 (59%), and 86 (37%) responded to the presession, postsession, and postexamination surveys, respectively. The majority of students indicated that the OMT videos helped them feel more prepared (98%) and more confident for their examination (78%), were a valuable addition to learning (97%), and would help increase confidence in using osteopathic manipulative medicine on patients (84%). Two-thirds of students indicated that the videos were superior to faculty demonstration from the stage. Compared with students from the previous year, no statistically significant improvement was noted on the total clinical competency examination scores. The faculty-created videos for teaching OMT techniques did not improve scores on the clinical competency examination but had subjective benefits as part of the OMT laboratory sessions. Instructional videos can serve as an alternative to live demonstration to allow more time in the laboratory for assessment and feedback.

Microvascular Anastomosis: Proposition of a Learning Curve.

2018-04-14

Learning to perform a microvascular anastomosis is one of the most difficult tasks in cerebrovascular surgery. Previous studies offer little regarding the optimal protocols to maximize learning efficiency. This failure stems mainly from lack of knowledge about the learning curve of this task. To delineate this learning curve and provide information about its various features including acquisition, improvement, consistency, stability, and recall. Five neurosurgeons with an average surgical experience history of 5 yr and without any experience in bypass surgery performed microscopic anastomosis on progressively smaller-caliber silastic tubes (Biomet, Palm Beach Gardens, Florida) during 24 consecutive sessions. After a 1-, 2-, and 8-wk retention interval, they performed recall test on 0.7-mm silastic tubes. The anastomoses were rated based on anastomosis patency and presence of any leaks. Improvement rate was faster during initial sessions compared to the final practice sessions. Performance decline was observed in the first session of working on a smaller-caliber tube. However, this rapidly improved during the following sessions of practice. Temporary plateaus were seen in certain segments of the curve. The retention interval between the acquisition and recall phase did not cause a regression to the prepractice performance level. Learning the fine motor task of microvascular anastomosis adapts to the basic rules of learning such as the "power law of practice." Our results also support the improvement of performance during consecutive sessions of practice. The objective evidence provided may help in developing optimized learning protocols for microvascular anastomosis.

A comprehensive examination was created and administered to assess student retention of therapeutic topics taught. Students demonstrated significantly improved overall scores on questions derived from the active-learning pedagogy used in Pharmacotherapy II and III compared to those derived from Pharmacotherapy I in which content was delivered by lecture. The use of active-learning strategies over lecture-based methods in pharmacotherapy courses resulted in higher retention of core content. Students' performance in areas taught using the discussion-based methodology was superior to that which was taught using lecture-based slide presentations.

Regulatory BC1 RNA in cognitive control.

PubMed

2017-07-01

Dendritic regulatory BC1 RNA is a non-protein-coding (npc) RNA that operates in the translational control of gene expression. The absence of BC1 RNA in BC1 knockout (KO) animals causes translational dysregulation that entails neuronal phenotypic alterations including prolonged epileptiform discharges, audiogenic seizure activity in vivo, and excessive cortical oscillations in the γ frequency band. Here we asked whether BC1 RNA control is also required for higher brain functions such as learning, memory, or cognition. To address this question, we used odor/object attentional set shifting tasks in which prefrontal cortical performance was assessed in a series of discrimination and conflict learning sessions. Results obtained in these behavioral trials indicate that BC1 KO animals were significantly impaired in their cognitive flexibility. When faced with conflicting information sources, BC1 KO animals committed regressive errors as they were compromised in their ability to disengage from recently acquired memories even though recall of such memories was in conflict with new situational context. The observed cognitive deficits are reminiscent of those previously described in subtypes of human autism spectrum disorders. © 2017 Iacoangeli et al.; Published by Cold Spring Harbor Laboratory Press.

2010-06-01

AI based Tutoring and Learning Path Adaptation are well known concepts in e-Learning scenarios today and increasingly applied in modern learning environments. In order to gain more flexibility and to enhance existing e-learning platforms, the OPUS One LMS Extension package will enable a generic Intelligent Tutored Adaptive Learning Environment, based on a holistic Multidimensional Instructional Design Model (PENTHA ID Model), allowing AI based tutoring and adaptation functionality to existing Web-based e-learning systems. Relying on "real time" adapted profiles, it allows content- / course authors to apply a dynamic course design, supporting tutored, collaborative sessions and activities, as suggested by modern pedagogy. The concept presented combines a personalized level of surveillance, learning activity- and learning path adaptation suggestions to ensure the students learning motivation and learning success. The OPUS One concept allows to implement an advanced tutoring approach combining "expert based" e-tutoring with the more "personal" human tutoring function. It supplies the "Human Tutor" with precise, extended course activity data and "adaptation" suggestions based on predefined subject matter rules. The concept architecture is modular allowing a personalized platform configuration.

Detecting Smoking Events Using Accelerometer Data Collected Via Smartwatch Technology: Validation Study

PubMed Central

Cole, Casey A; Anshari, Dien; Lambert, Victoria; Thrasher, James F

2017-01-01

Background Smoking is the leading cause of preventable death in the world today. Ecological research on smoking in context currently relies on self-reported smoking behavior. Emerging smartwatch technology may more objectively measure smoking behavior by automatically detecting smoking sessions using robust machine learning models. Objective This study aimed to examine the feasibility of detecting smoking behavior using smartwatches. The second aim of this study was to compare the success of observing smoking behavior with smartwatches to that of conventional self-reporting. Methods A convenience sample of smokers was recruited for this study. Participants (N=10) recorded 12 hours of accelerometer data using a mobile phone and smartwatch. During these 12 hours, they engaged in various daily activities, including smoking, for which they logged the beginning and end of each smoking session. Raw data were classified as either smoking or nonsmoking using a machine learning model for pattern recognition. The accuracy of the model was evaluated by comparing the output with a detailed description of a modeled smoking session. Results In total, 120 hours of data were collected from participants and analyzed. The accuracy of self-reported smoking was approximately 78% (96/123). Our model was successful in detecting 100 of 123 (81%) smoking sessions recorded by participants. After eliminating sessions from the participants that did not adhere to study protocols, the true positive detection rate of the smartwatch based-detection increased to more than 90%. During the 120 hours of combined observation time, only 22 false positive smoking sessions were detected resulting in a 2.8% false positive rate. Conclusions Smartwatch technology can provide an accurate, nonintrusive means of monitoring smoking behavior in natural contexts. The use of machine learning algorithms for passively detecting smoking sessions may enrich ecological momentary assessment protocols and cessation intervention studies that often rely on self-reported behaviors and may not allow for targeted data collection and communications around smoking events.

Further characterization of an aversive learning task in Drosophila melanogaster: intensity of the stimulus, relearning, and use of rutabaga mutants.

2007-11-01

Various learning tasks have been described in Drosophila melanogaster, flies being either tested in groups or at the individual level. Le Bourg and Buecher (Anim Learn Behav 33:330-341, 2002) have designed a task at the individual level: photopositive flies crossing a T-maze learn to prefer the dark exit when the lighted one is associated with the presence of aversive stimuli (humidity and quinine). Previous studies have reported various results (e.g. no effect of age) and the present article further characterizes this task by studying the possible effects of: (1) the intensity of the stimuli (quantity of water or concentration of quinine), (2) various delays between two learning sessions on the learning score at the second session, (3) the rutabaga learning mutation on the learning score. More concentrated quinine solutions increased learning scores but the quantity of water had no effect. Learning scores at the second session were higher with shorter delays between the two learning sessions and retrograde amnesia could decrease this memory score. rutabaga mutants showed learning deficits as in experiments testing groups of flies. This learning task could particularly be used to verify whether learning mutants isolated after experiments testing flies in groups display similar deficits when tested at the individual level.

Learning prosthetic vision: a virtual-reality study.

Chen, Spencer C; Hallum, Luke E; Lovell, Nigel H; Suaning, Gregg J

2005-09-01

Acceptance of prosthetic vision will be heavily dependent on the ability of recipients to form useful information from such vision. Training strategies to accelerate learning and maximize visual comprehension would need to be designed in the light of the factors affecting human learning under prosthetic vision. Some of these potential factors were examined in a visual acuity study using the Landolt C optotype under virtual-reality simulation of prosthetic vision. Fifteen normally sighted subjects were tested for 10-20 sessions. Potential learning factors were tested at p < 0.05 with regression models. Learning was most evident across-sessions, though 17% of sessions did express significant within-session trends. Learning was highly concentrated toward a critical range of optotype sizes, and subjects were less capable in identifying the closed optotype (a Landolt C with no gap, forming a closed annulus). Training for implant recipients should target these critical sizes and the closed optotype to extend the limit of visual comprehension. Although there was no evidence that image processing affected overall learning, subjects showed varying personal preferences.

Effects of a Context Shift and Multiple Context Extinction on Reactivity to Alcohol Cues

PubMed Central

MacKillop, James; Lisman, Stephen A.

2008-01-01

Cue exposure treatment (CET) attempts to reduce the influence of conditioned substance cues on addictive behavior via prolonged cue exposure with response prevention (i.e., extinction), but has received only modest empirical support in clinical trials. This may be because extinction learning appears to be context dependent and a change in context may result in a return of conditioned responding (i.e., renewal), although this has received only limited empirical examination. The current study used a four-session laboratory analogue of CET to examine whether a change in context following three sessions of alcohol cue exposure with response prevention would result in renewal of conditioned responding. In addition, this study examined whether conducting extinction in multiple contexts would attenuate renewal of conditioned responding. In a one-way between-subjects design, 73 heavy drinkers (71% male) were randomized to three conditions: 1) single context extinction (extinction to alcohol cues in the same context for three sessions followed by a context shift at the fourth session); 2) multiple context extinction (extinction to alcohol cues in different contexts each day for all four sessions); and 3) pseudo-extinction control condition (exposure to neutral cues in the same context for three sessions followed by exposure to alcohol cues at the fourth session). The results revealed the predicted cue reactivity and extinction effects, but the hypotheses that a context shift would generate renewed cue reactivity and that multiple contexts would enhance extinction were not supported. Methodological aspects of the study and the need for parametric data on the context dependency of extinction to alcohol cues are discussed. PMID:18729687

7-Nitroindazole, a neuronal nitric oxide synthase inhibitor, impairs passive-avoidance and elevated plus-maze memory performance in rats.

The role of nitric oxide (NO) on cognitive performance in a modified elevated plus-maze (mEPM) and passive-avoidance (PA) task was investigated by using the NO synthase (NOS) inhibitor 7-nitroindazole (7-NI) and an NO precursor l-arginine. The interaction between the activation of N-methyl-d-aspartate (NMDA) receptors and NO synthesis on memory retention was also studied. 7-NI, l-arginine or MK-801, a non-competitive NMDA receptor antagonist were injected intraperitoneally (i.p) to male Wistar rats 30 min before the first training session of the PA test or 30 min before on the first day testing (acquisition session) of mEPM task. Transfer latency, the time rat took to move from the open arm to the enclosed arm, was used as an index of learning and memory in a mEPM test. The retention session was performed 24 h after the acquisition one. In the PA task, the retention test was carried out 24 h after training and reduction of retention latency was used to evaluate the acquisition of learning and memory. Blood glucose level and locomotor activity of the rats was also evaluated. 7-NI (10, 20, 25, 50 mg/kg) and MK-801 (0.15 mg/kg) significantly prolonged the transfer latency on retention session in a mEPM test and shortened step-through latency in PA test. 7-NI-induced impairment in memory and learning was partly reversed by l-arginine (200 mg/kg), a competitive substrate for NOS. However subeffective doses of 7-NI (5 mg/kg) and MK-801 (0.075 mg/kg) given in combination significantly impaired plus-maze and PA performances in rats. Thus NMDA receptor mediated NO pathways may be implicated in the PA and mEPM behaviours in rats. Since 7-NI does not affect blood pressure and did not alter blood glucose level and locomotor activity in conscious rats, 7-NI-induced impairment of memory is not due to either hypertension, changes in blood glucose level or effects on locomotor activity.

Use of Live Interactive Webcasting for an International Postgraduate Module in eHealth: Case Study Evaluation

2009-01-01

Background Producing “traditional” e-learning can be time consuming, and in a topic such as eHealth, it may have a short shelf-life. Students sometimes report feeling isolated and lacking in motivation. Synchronous methods can play an important part in any blended approach to learning. Objective The aim was to develop, deliver, and evaluate an international postgraduate module in eHealth using live interactive webcasting. Methods We developed a hybrid solution for live interactive webcasting using a scan converter, mixer, and digitizer, and video server to embed a presenter-controlled talking head or copy of the presenter’s computer screen (normally a PowerPoint slide) in a student chat room. We recruited 16 students from six countries and ran weekly 2.5-hour live sessions for 10 weeks. The content included the use of computers by patients, patient access to records, different forms of e-learning for patients and professionals, research methods in eHealth, geographic information systems, and telehealth. All sessions were recorded—presentations as video files and the student interaction as text files.

Producing "traditional" e-learning can be time consuming, and in a topic such as eHealth, it may have a short shelf-life. Students sometimes report feeling isolated and lacking in motivation. Synchronous methods can play an important part in any blended approach to learning. The aim was to develop, deliver, and evaluate an international postgraduate module in eHealth using live interactive webcasting. We developed a hybrid solution for live interactive webcasting using a scan converter, mixer, and digitizer, and video server to embed a presenter-controlled talking head or copy of the presenter's computer screen (normally a PowerPoint slide) in a student chat room. We recruited 16 students from six countries and ran weekly 2.5-hour live sessions for 10 weeks. The content included the use of computers by patients, patient access to records, different forms of e-learning for patients and professionals, research methods in eHealth, geographic information systems, and telehealth. All sessions were recorded-presentations as video files and the student interaction as text files. Students were sent an email questionnaire of mostly open questions seeking their views of this form of learning.

To provide a virtual environment for pharmacy students to learn United States Pharmacopeia Chapter 797 (USP 797) requirements, while recognizing the role of pharmacists in the safe use of intravenous (IV) medications. A virtual laboratory was created that included stations for IV medications, product verification, medication safety, and patient cases pertaining to high-alert medications. Pharmacy students used 3-D glasses and a wireless controller to navigate through the session and identify violations of USP 797 regulations. Pre-assessments and post-assessments were administered to students who completed the session in each of the 2 years it was offered. In the first year, 88% of students strongly agreed or agreed that the sessions met their expectation. Following their APPE clerkship, 92% of these students felt the virtual IV room prepared them for the IV clean room experience. In the second year, 88% of students felt the experience enhanced their understanding of clean room procedures. After session completion, 75% of participants perceived medication errors to be more significant. Written examinations also were administered and students' mean scores improved significantly compared to those of students' prior to implementation of the session (89.6% in year 0; 91.2% in year 1; and 96.1% in year 2). The immersive virtual environment is a contemporary and effective way to teach USP 797 requirements and enhance the awareness of medication errors.

Neonatal ethanol exposure results in dose-dependent impairments in the acquisition and timing of the conditioned eyeblink response and altered cerebellar interpositus nucleus and hippocampal CA1 unit activity in adult rats.

Exposure to ethanol in neonatal rats results in reduced neuronal numbers in the cerebellar cortex and deep nuclei of juvenile and adult animals. This reduction in cell numbers is correlated with impaired delay eyeblink conditioning (EBC), a simple motor learning task in which a neutral conditioned stimulus (CS; tone) is repeatedly paired with a co-terminating unconditioned stimulus (US; periorbital shock). Across training, cell populations in the interpositus (IP) nucleus model the temporal form of the eyeblink-conditioned response (CR). The hippocampus, though not required for delay EBC, also shows learning-dependent increases in CA1 and CA3 unit activity. In the present study, rat pups were exposed to 0, 3, 4, or 5 mg/kg/day of ethanol during postnatal days (PD) 4-9. As adults, CR acquisition and timing were assessed during 6 training sessions of delay EBC with a short (280 ms) interstimulus interval (ISI; time from CS onset to US onset) followed by another 6 sessions with a long (880 ms) ISI. Neuronal activity was recorded in the IP and area CA1 during all 12 sessions. The high-dose rats learned the most slowly and, with the moderate-dose rats, produced the longest CR peak latencies over training to the short ISI. The low dose of alcohol impaired CR performance to the long ISI only. The 3E (3 mg/kg/day of ethanol) and 5E (5 mg/kg/day of ethanol) rats also showed slower-than-normal increases in learning-dependent excitatory unit activity in the IP and CA1. The 4E (4 mg/kg/day of ethanol) rats showed a higher rate of CR production to the long ISI and enhanced IP and CA1 activation when compared to the 3E and 5E rats. The results indicate that binge-like ethanol exposure in neonatal rats induces long-lasting, dose-dependent deficits in CR acquisition and timing and diminishes conditioning-related neuronal excitation in both the cerebellum and hippocampus.

Sleep and memory. I: The influence of different sleep stages on memory.

PubMed

Rotenberg, V S

1992-01-01

A new approach to the sleep stages role in memory is discussed in the context of the two opposite patterns of behavior-search activity and renunciation of search. Search activity is activity designed to change the situation (or the subjects attitudes to it) in the absence of a definite forecast of the results of such activity, but with the constant consideration of these results at all stages of activity. Search activity increases general adaptability and body resistance while renunciation of search decreases adaptability and requires REM sleep for its compensation. Unprepared learning, which is often accompanied by failures on the first steps of learning, is suggested to produce renunciation of search, which decreases learning ability, suppress retention, and increase REM sleep requirement. A prolonged REM sleep deprivation before training causes learned helplessness and disturbs the learning process, while short REM sleep deprivation cause the "rebound" of the compensatory search activity that interferes with passive avoidance. REM sleep deprivation performed after a training session can increase distress caused by a training procedure, with the subsequent negative outcome on retention.

Using synchronous software in Web-based nursing courses.

To promote learning and enhance immediacy and satisfaction, a college of nursing at a large research I southern university undertook a pilot project to incorporate synchronous classroom software into an ongoing online program. Two synchronous class sessions using voice over Internet protocol were offered in the Community/Public Health Nursing course through Elluminate Live! Upon conclusion of the lecture, students were divided into breakout groups to work on group projects. Surveys were administered to the students and faculty before and after the class sessions. Evaluation of the pedagogical strategies used in the synchronous sessions was conducted by instructional technology faculty. Students in the pilot group reported higher levels of satisfaction with the Web-based course with synchronous sessions. In addition, students reported that group time at the end of the session was helpful for completing group projects. A majority responded that synchronous session activities and assignments facilitated their understanding of course content. This article presents a description of the synchronous classroom pilot project along with recommendations for implementation and pedagogical approaches.

Klement, Brenda J.; Paulsen, Douglas F.; Wineski, Lawrence E.

2016-01-01

Clinical correlations are tools to assist students in associating basic science concepts with a medical application or disease. There are many forms of clinical correlations and many ways to use them in the classroom. Five types of clinical correlations that may be embedded within basic science courses have been identified and described. (1) Correlated examples consist of superficial clinical information or stories accompanying basic science concepts to make the information more interesting and relevant. (2) Interactive learning and demonstrations provide hands-on experiences or the demonstration of a clinical topic. (3) Specialized workshops have an application-based focus, are more specialized than typical laboratory sessions, and range in complexity from basic to advanced. (4) Small-group activities require groups of students, guided by faculty, to solve simple problems that relate basic science information to clinical topics. (5) Course-centered problem solving is a more advanced correlation activity than the others and focuses on recognition and treatment of clinical problems to promote clinical reasoning skills. Diverse teaching activities are used in basic science medical education, and those that include clinical relevance promote interest, communication, and collaboration, enhance knowledge retention, and help develop clinical reasoning skills.

Dubey, Suparna; Dubey, Ashok Kumar

The curriculum of pathology is conventionally "taught" in a series of didactic lectures, which promotes learning by rote. In this study, case-based learning (CBL) was introduced to assess its effect on higher order cognition and problem-solving skills in undergraduate medical students. The prescribed syllabus of hepatobiliary system was delivered to the undergraduate medical students of the fourth semester by conventional didactic lectures. A pretest, which contained questions designed to test both analysis and recall, was administered, followed by CBL sessions, in the presence of a facilitator, encouraging active discussion among students. Students were then assessed using a similar posttest. The perceptions of the students and the faculty were gathered by means of feedback questionnaires. The scores obtained by the students in the pre- and post-test were compared by paired t -test. Eighty-one students participated in CBL sessions, with 95.06% expressing a desire for more such sessions, preferably in all the topics. The faculty members also felt that CBL would be beneficial for the students but opined that it should be restricted to some topics. CBL was found to cause a highly significant ( P < 0.0001) improvement in the students' higher levels of cognition, whereas the lower orders of cognition remained unaffected ( P = 0.2048). CBL promotes active learning and helps in the development of critical thinking and analysis in undergraduate medical students. Although it is resource-intensive, an attempt should be made to incorporate it along with lectures in clinically important topics.

Fostering interaction in the online classroom is an important consideration in ensuring that students actively create their own knowledge and reach a high level of achievement in science courses. This study focuses on fostering interaction in an online introductory nutrition course offered in a public institution of higher education in Hawai'i, USA. Interactive features included synchronous discussions and polls in scheduled sessions, and social media tools for sharing of information and resources. Qualitative student feedback was solicited regarding the new course features. Findings indicated that students who attended monthly synchronous sessions valued live interaction with peers and the instructor. Issues identified included technical difficulties during synchronous sessions, lack of participation on the part of fellow students in discussion and inability to attend synchronous sessions due to scheduling conflicts. In addition, few students made use of the opportunity to interact via social media. While students indicated that the interactive components of the course were valuable, several areas in which improvement may be made remain. Future studies may explore potential solutions to issues identified with new features to further promote interaction and foster learning in the course. Recommendations for instructors who are interested in offering online science courses in higher education are provided.

Facilitating small groups: how to encourage student learning.

PubMed

Kitchen, Mark

2012-02-01

Many clinicians are involved in medical education, with small group teaching (SGT) forming a significant part of their work. Most facilitate these sessions by experience and common sense: less than one-third of them have received formal training in SGT. Evidence suggests small group productivity depends on good facilitation rather than on topic knowledge. Applying the fundamental concepts of SGT will lead to improvements in the quality of clinicians' teaching and in student learning. Good SGT creates the perfect environment for learning and discussion, without the need for didactic teaching. SGT emphasises the role of students in sharing and discussing their ideas in a safe learning environment, without domination by the tutor. This article provides clinicians with basic requirements for effective session design and planning, explains how to encourage student participation, how to manage students as a group, how to manage student learning, and how to recognise and deal with problems. Active facilitation and group management is the key to success in SGT, and consequently better learning outcomes. Improving the facilitation skills of clinical teachers makes teaching more effective, stimulating, and enjoyable for both tutors and students. © Blackwell Publishing Ltd 2012.

Effectiveness of a Constructivist Approach to Science Instruction for Prospective Elementary Teachers

Liang, Ling L.; Gabel, Dorothy L.

2005-08-01

This study examines the effectiveness of a new constructivist curriculum model (Powerful Ideas in Physical Science) in improving prospective teachers’ understanding of science concepts, in fostering a learning environment supporting conceptual understanding, and in promoting positive attitudes toward learning and teaching science and chemistry in particular. A non-equivalent pretest post-test control-group design was employed. Analysis of covariance and repeated-measures analyses of variance were performed to analyze the scores on concept tests and attitude surveys. Data from videotaped observations of laboratory sessions and interviews of prospective teachers were analyzed by employing a naturalistic inquiry method to provide insights into the process of science learning and teaching for the teacher trainees. The interpretations were made based on the findings that could be corroborated by both methodologies. Conclusions and limitations of the present study as well as recommendations for future implementation of constructivist science curriculum in general are also included.

Learning to identify crowded letters: Does the learning depend on the frequency of training?

Chung, Susana T. L.; Truong, Sandy R.

2012-01-01

Performance for many visual tasks improves with training. The magnitude of improvement following training depends on the training task, number of trials per training session and the total amount of training. Does the magnitude of improvement also depend on the frequency of training sessions? In this study, we compared the learning effect for three groups of normally sighted observers who repeatedly practiced the task of identifying crowded letters in the periphery for six sessions (1000 trials per session), according to three different training schedules — one group received one session of training everyday, the second group received a training session once a week and the third group once every two weeks. Following six sessions of training, all observers improved in their performance of identifying crowded letters in the periphery. Most importantly, the magnitudes of improvement were similar across the three training groups. The improvement was accompanied by a reduction in the spatial extent of crowding, an increase in the size of visual span and a reduction in letter-size threshold. The magnitudes of these accompanied improvements were also similar across the three training groups. Our finding that the effectiveness of visual perceptual learning is similar for daily, weekly and biweekly training has significant implication for adopting perceptual learning as an option to improve visual functions for clinical patients.

Measuring meaningful learning in the undergraduate chemistry laboratory

NASA Astrophysics Data System (ADS)

Galloway, Kelli R.

The undergraduate chemistry laboratory has been an essential component in chemistry education for over a century. The literature includes reports on investigations of singular aspects laboratory learning and attempts to measure the efficacy of reformed laboratory curriculum as well as faculty goals for laboratory learning which found common goals among instructors for students to learn laboratory skills, techniques, experimental design, and to develop critical thinking skills. These findings are important for improving teaching and learning in the undergraduate chemistry laboratory, but research is needed to connect the faculty goals to student perceptions. This study was designed to explore students' ideas about learning in the undergraduate chemistry laboratory. Novak's Theory of Meaningful Learning was used as a guide for the data collection and analysis choices for this research. Novak's theory states that in order for meaningful learning to occur the cognitive, affective, and psychomotor domains must be integrated. The psychomotor domain is inherent in the chemistry laboratory, but the extent to which the cognitive and affective domains are integrated is unknown. For meaningful learning to occur in the laboratory, students must actively integrate both the cognitive domain and the affective domains into the "doing" of their laboratory work. The Meaningful Learning in the Laboratory Instrument (MLLI) was designed to measure students' cognitive and affective expectations and experiences within the context of conducting experiments in the undergraduate chemistry laboratory. Evidence for the validity and reliability of the data generated by the MLLI were collected from multiple quantitative studies: a one semester study at one university, a one semester study at 15 colleges and universities across the United States, and a longitudinal study where the MLLI was administered 6 times during two years of general and organic chemistry laboratory courses. Results from these studies revealed students' narrow cognitive expectations for learning that go largely unmet by their experiences and diverse affective expectations and experiences. Concurrently, a qualitative study was carried out to describe and characterize students' cognitive and affective experiences in the undergraduate chemistry laboratory. Students were video recorded while performing one of their regular laboratory experiments and then interviewed about their experiences. The students' descriptions of their learning experiences were characterized by their overreliance on following the experimental procedure correctly rather than developing process-oriented problem solving skills. Future research could use the MLLI to intentionally compare different types of laboratory curricula or environments.

Di Renzone, Simone; Frati, Serena; Montalbano, Vera

An investigation on student understanding of waves is performed during an optional laboratory realized in informal extracurricular way with few, interested and talented pupils. The background and smart intuitions of students rendered the learning path very dynamic and ambitious. The activities started by investigating the basic properties of waves by means of a Shive wave machine. In order to make quantitative observed phenomena, the students used a camcorder and series of measures were obtained from the captured images. By checking the resulting data, it arose some learning difficulties especially in activities related to the laboratory. This experience was the starting point for a further analysis on disciplinary knots and learning problems in the physics of waves in order to elaborate a teaching-learning proposal on this topic.

Abstract Objective To determine family medicine residents’ learning behaviour and preferences outside of clinical settings in order to help guide the development of an effective academic program that can maximize their learning. Design Retrospective descriptive analysis of academic learning logs submitted by residents as part of their academic training requirements between 2008 and 2011. Setting London, Ont. Participants All family medicine residents at Western University who had completed their academic program requirements (N = 72) by submitting 300 or more credits (1 credit = 1 hour). Main outcome measures Amount of time spent on various learning modalities, location where the learning took place, resources used for self-study, and the objective of the learning activity. Results A total of 72 residents completed their academic requirements during the study period and logged a total of 25 068 hours of academic learning. Residents chose to spend most of their academic time engaging in self-study (44%), attending staff physicians’ teaching sessions (20%), and participating in conferences, courses, or workshops (12%) and in postgraduate medical education sessions (12%). Textbooks (26%), medical journals (20%), and point-of-care resources (12%) were the 3 most common resources used for self-study. The hospital (32%), residents’ homes (32%), and family medicine clinics (14%) were the most frequently cited locations where academic learning occurred. While all physicians used a variety of educational activities, most residents (67%) chose self-study as their primary method of learning. The topic for academic learning appeared to have some influence on the learning modalities used by residents. Conclusion Residents used a variety of learning modalities and chose self-study over other more traditional modalities (eg, lectures) for most of their academic learning. A successful academic program must take into account residents’ various learning preferences and habits while providing guidance and training in the use of more effective learning methods and resources to maximize educational outcomes.

TThe Citizen Science Program H2O SOS: Help Heal the Ocean—Student Operated Solutions: Operation Climate Change, teaches middle and high school students about ocean threats related to climate change through hands-on activities and learning experiences in the field. During each session (in-class or after-school as a club), students build an understanding about how climate change impacts our oceans using resources provided by ExplorOcean (hands-on activities, presentations, multi-media). Through a student leadership model, students present lessons to each other, interweaving a deep learning of science, 21st century technology, communication skills, and leadership. After participating in learning experiences and activities related to 6 key climate change concepts: 1) Introduction to climate change, 2) Increased sea temperatures, 3) Ocean acidification, 4) Sea level rise, 5) Feedback mechanisms, and 6) Innovative solutions. H2O SOS- Operation Climate change participants select one focus issue and use it to design a multi-pronged campaign to increase awareness about this issue in their local community. The campaign includes social media, an interactive activity, and a visual component. All participating clubs that meet participation and action goals earn a field trip to Ocean Quest where they dive deeper into their selected issue through hands-on activities, real-world investigations, and interviews or presentations with experts. In addition to self-selected opportunities to showcase their focus issue, teams will participate in one of several key events identified by Ocean Quest.

The role of numeracy on client knowledge in BRCA genetic counseling.

Portnoy, David B; Roter, Debra; Erby, Lori H

2010-10-01

To assess the impact of numeracy and health literacy on client's ability to learn information orally communicated during a BRCA 1/2 genetic counseling session. Fifty-nine videotaped simulated genetic counseling sessions were shown to 246 analogue clients (AC) recruited to imagine themselves as the client in the genetic counseling session. AC numeracy, genetic literacy, state and trait anxiety, and decisional conflict were assessed. The primary outcome was AC learning about BRCA 1/2. Health literacy and numeracy were moderately correlated, and each independently predicted learning. Higher numeracy was associated with higher knowledge scores only among ACs with adequate literacy. Decisional conflict was not related to literacy, numeracy, or knowledge acquisition. It was, however, inversely related to state anxiety so that the higher post-session state anxiety, the lower the AC's decisional conflict. Numeracy and health literacy are associated with learning of orally communicated information during genetic counseling. It appears that numeracy can facilitate learning for literate subjects; it does not, however, make any difference in learning ability of clients with significant literacy deficits. Numeracy plays an important role in client's ability to learn information communicated during medical sessions, especially among clients who are otherwise regarded as literate.

Vagal tone during infant contingency learning and its disruption.

PubMed

Sullivan, Margaret Wolan

2016-04-01

This study used contingency learning to examine changes in infants' vagal tone during learning and its disruption. The heart rate of 160 five-month-old infants was recorded continuously during the first of two training sessions as they experienced an audiovisual event contingent on their pulling. Maternal reports of infant temperament were also collected. Baseline vagal tone, a measure of parasympathetic regulation of the heart, was related to vagal levels during the infants' contingency learning session, but not to their learner status. Vagal tone levels did not vary significantly over session minutes. Instead, vagal tone levels were a function of both individual differences in learner status and infant soothability. Vagal levels of infants who learned in the initial session were similar regardless of their soothability; however, vagal levels of infants who learned in a subsequent session differed as a function of soothability. Additionally, vagal levels during contingency disruption were significantly higher among infants in this group who were more soothable as opposed to those who were less soothable. The results suggest that contingency learning and disruption is associated with stable vagal tone in the majority of infants, but that individual differences in attention processes and state associated with vagal tone may be most readily observed during the disruption phase. © 2015 Wiley Periodicals, Inc.

Orbitofrontal cortex inactivation impairs between- but not within-session Pavlovian extinction: an associative analysis.

PubMed

Panayi, Marios C; Killcross, Simon

2014-02-01

The orbitofrontal cortex (OFC) is argued to be the neural locus of Pavlovian outcome expectancies. Reinforcement learning theories argue that extinction learning in Pavlovian procedures is caused by the discrepancy between the expected value of the outcome (US) that is elicited by a predictive stimulus (CS), and the lack of experienced US. If the OFC represents Pavlovian outcome expectancies that are necessary for extinction learning, then disrupting OFC function prior to extinction training should impair extinction learning. This was tested. In experiment 1, Long Evans rats received infusions of saline or muscimol targeting the lateral OFC prior to three appetitive Pavlovian extinction sessions. Muscimol infused into the OFC disrupted between-session but not within-session extinction behaviour. This finding was not due to muscimol infusions disrupting the memory consolidation process per se as there was no effect of muscimol infusion when administered immediately post session (experiment 2). These findings support a role for the OFC in representing outcome expectancies that are necessary for learning. A number of ways in which disrupting outcome expectancy information might block learning will be discussed in the context of traditional associative learning theories and the associative structures they depend on.

Seeley, Corrine J; Beninger, Richard J; Smith, Carlyle T

2014-01-01

The Iowa Gambling Task (IGT) is widely used to assess real life decision-making impairment in a wide variety of clinical populations. Our study evaluated how IGT learning occurs across two sessions, and whether a period of intervening sleep between sessions can enhance learning. Furthermore, we investigate whether pre-sleep learning is necessary for this improvement. A 200-trial version of the IGT was administered at two sessions separated by wake, sleep or sleep and wake (time-of-day control). Participants were categorized as learners and non-learners based on initial performance in session one. In session one, participants initially preferred the high-frequency reward decks B and D, however, a subset of learners decreased choice from negative expected value 'bad' deck B and increased choices towards with a positive expected value 'good' decks (decks C and D). The learners who had a period of sleep (sleep and sleep/wake control conditions) between sessions showed significantly larger reduction in choices from deck B and increase in choices from good decks compared to learners that had intervening wake. Our results are the first to show that post-learning sleep can improve performance on a complex decision-making task such as the IGT. These results provide new insights into IGT learning and have important implications for understanding the neural mechanisms of "sleeping on" a decision.

Poor skills generalization poses a major barrier to successful outcomes of rehabilitation after traumatic brain injury (TBI). Error-based learning (EBL) is a relatively new intervention approach that aims to promote skills generalization by teaching people internal self-regulation skills, or how to anticipate, monitor and correct their own errors. This paper describes the protocol of a study that aims to compare the efficacy of EBL and errorless learning (ELL) for improving error self-regulation, behavioral competency, awareness of deficits and long-term outcomes after TBI. This randomized, controlled trial (RCT) has two arms (EBL and ELL); each arm entails 8 × 2 h training sessions conducted within the participants' homes. The first four sessions involve a meal preparation activity, and the final four sessions incorporate a multitasking errand activity. Based on a sample size estimate, 135 participants with severe TBI will be randomized into either the EBL or ELL condition. The primary outcome measure assesses error self-regulation skills on a task related to but distinct from training. Secondary outcomes include measures of self-monitoring and self-regulation, behavioral competency, awareness of deficits, role participation and supportive care needs. Assessments will be conducted at pre-intervention, post-intervention, and at 6-months post-intervention. This study seeks to determine the efficacy and long-term impact of EBL for training internal self-regulation strategies following severe TBI. In doing so, the study will advance theoretical understanding of the role of errors in task learning and skills generalization. EBL has the potential to reduce the length and costs of rehabilitation and lifestyle support because the techniques could enhance generalization success and lifelong application of strategies after TBI.

Sessional staff is increasingly involved in teaching at universities, playing a pivotal role in bridging the gap between theory and practice for students, especially in the health professions, including pharmacy. Although sessional staff numbers have increased substantially in recent years, limited attention has been paid to the quality of teaching and learning provided by this group. This review will discuss the training and support of sessional staff, with a focus on Australian universities, including the reasons for and potential benefits of training, and structure and content of training programs. Although sessional staff views these programs as valuable, there is a lack of in-depth evaluations of the outcomes of the programs for sessional staff, students and the university. Quality assurance of such programs is only guaranteed, however, if these evaluations extend to the impact of this training and support on student learning.

The training literature suggests that ongoing support following initial therapist training enhances training outcomes, yet little is known about what occurs during ongoing support and what accounts for its effectiveness. The present study examined consultation sessions provided to 99 clinicians following training in cognitive-behavioral therapy for youth anxiety. The 104 recorded consultation sessions were coded for content and consultative methods. It was hypothesized that behavioral rehearsal (an active learning technique) would predict therapist adherence, skill, self-efficacy, and satisfaction at post-consultation. Regression analyses found no significant relation, however, clinician involvement during consultation sessions positively moderated the relationship between behavioral rehearsals and skill. Implications, limitations, and future directions are discussed. PMID:23616234

2011-01-01

This study examined the effects of stress on taste perception. Participants (N = 38; 21 women) completed two laboratory sessions: one stress (public speaking, math, and cold pressor) and one control rest session. The taste perception test was conducted at the end of each session and included rating the intensity and pleasantness of sweet, salty, sour, and savory solutions at suprathreshold concentrations. Cardiovascular, hormonal, and mood measures were collected throughout the sessions. Participants showed the expected changes in cardiovascular, hormonal, and mood measures in response to stress. Reported intensity of the sweet solution was significantly lower on the stress day than on the rest day. Cortisol level post stress predicted reduced intensity of salt and sour, suggesting that stress-related changes in adrenocortical activity were related to reduced taste intensity. Results indicate that acute stress may alter taste perception, and ongoing research investigates the extent to which these changes mediate effects of stress on appetite. PMID:22091733

The Laboratorio Didattica e Divulgazione Scientifica of the Istituto Nazionale di Geofisica e Vulcanologia (INGV's Educational and Outreach Laboratory) organized activity with kids to convey scientific knowledge and to promote research on Earth Science, focusing on volcanic and seismic hazard. The combination of games and learning in educational activity can be a valuable tool for study of complex phenomena. Hands-on activity may help in engage kids in a learning process through direct participation that significantly improves the learning performance of children. Making learning fun motivate audience to pay attention on and stay focused on the subject. We present the experience of the hand-on laboratory "Laboratorio goloso per bambini curiosi di scienza (a delicious hands-on laboratory for kids curious about science)", performed in Frascati during the 2013 European Researchers' Night, promoted by the European Commission, as part of the program organized by the Laboratorio Didattica e Divulgazione Scientifica in the framework of Associazione Frascati Scienza (http://www.frascatiscienza.it/). The hand-on activity were designed for primary schools to create enjoyable and unusual tools for learning Earth Science. During this activity kids are involved with something related to everyday life, such as food, through manipulation, construction and implementation of simple experiments related to Earth dynamics. Children become familiar with scientific concepts such as composition of the Earth, plates tectonic, earthquakes and seismic waves propagation and experience the effect of earthquakes on buildings, exploring their important implications for seismic hazard. During the activity, composed of several steps, participants were able to learn about Earth inner structure, fragile lithosphere, waves propagations, impact of waves on building ecc.., dealing with eggs, cookies, honey, sugar, polenta, flour, chocolate, candies, liquorice sticks, bread, pudding and sweets. The activity was successful as more than 500 kids of different ages participated with great enthusiasm, as well as they parents, and gave the chance to explore and manipulate even complex scientific arguments without getting the feeling of having doing this.

Objective. To implement and evaluate the use of a situated-learning experience to prepare second-year pharmacy students to conduct medication history interviews in preparation for introductory pharmacy practice experiences (IPPE) at ambulatory clinic sites. Design. Second-year doctor of pharmacy (PharmD) students (n=200) used the Medication Mysteries Infinite Case Tool, a game-like educational tool in which groups of 3 students assumed the roles of pharmacist, patient, and observer and rolled a die and drew cards to determine the drugs, patient personality, medication problems, and other variables that guided a medication history taking session. Assessment. After the laboratory session, faculty members assessed students’ medication history-taking skills. One hundred sixteen (58%) and 78 (39%) of 200 students achieved excellence or competence, respectively, on the final assessment. Two weeks after the assessment, 53 of 200 (26.5%) students completed a survey instrument. The respondents indicated that their self-confidence in conducting medical history taking significantly improved following completion of the learning experience. Conclusion. Using the Medication Mysteries Infinite Case Tool increased students’ confidence and skills in conducting medication history taking prior to their clinical IPPE experience. PMID:23788816

The advent of mobile DNA sequencers has made it possible to generate DNA sequencing data outside of laboratories and genome centers. Here, we report our experience of using the MinION, a mobile sequencer, in a 13-week academic course for undergraduate and graduate students. The course consisted of theoretical sessions that presented fundamental topics in genomics and several applied hackathon sessions. In these hackathons, the students used MinION sequencers to generate and analyze their own data and gain hands-on experience in the topics discussed in the theoretical classes. The manuscript describes the structure of our class, the educational material, and the lessons we learned in the process. We hope that the knowledge and material presented here will provide the community with useful tools to help educate future generations of genome scientists.

The availability of transgenic mice mimicking selective human neurodegenerative and psychiatric disorders calls for new electrophysiological and microstimulation techniques capable of being applied in vivo in this species. In this article, we will concentrate on experiments and techniques developed in our laboratory during the past few years. Thus we have developed different techniques for the study of learning and memory capabilities of wild-type and transgenic mice with deficits in cognitive functions, using classical conditioning procedures. These techniques include different trace (tone/SHOCK and shock/SHOCK) conditioning procedures ? that is, a classical conditioning task involving the cerebral cortex, including the hippocampus. We have also developed implantation and recording techniques for evoking long-term potentiation (LTP) in behaving mice and for recording the evolution of field excitatory postsynaptic potentials (fEPSP) evoked in the hippocampal CA1 area by the electrical stimulation of the commissural/Schaffer collateral pathway across conditioning sessions. Computer programs have also been developed to quantify the appearance and evolution of eyelid conditioned responses and the slope of evoked fEPSPs. According to the present results, the in vivo recording of the electrical activity of selected hippocampal sites during classical conditioning of eyelid responses appears to be a suitable experimental procedure for studying learning capabilities in genetically modified mice, and an excellent model for the study of selected neuropsychiatric disorders compromising cerebral cortex functioning.

An inquiry-based biochemistry laboratory structure emphasizing competency in the scientific process: a guided approach with an electronic notebook format.

The laboratory setting is an exciting and gratifying place to teach because you can actively engage the students in the learning process through hands-on activities; it is a dynamic environment amenable to collaborative work, critical thinking, problem-solving and discovery. The guided inquiry-based approach described here guides the students through their laboratory work at a steady pace that encourages them to focus on quality observations, careful data collection and thought processes surrounding the chemistry involved. It motivates students to work in a collaborative manner with frequent opportunities for feedback, reflection, and modification of their ideas. Each laboratory activity has four stages to keep the students' efforts on track: pre-lab work, an in-lab discussion, in-lab work, and a post-lab assignment. Students are guided at each stage by an instructor created template that directs their learning while giving them the opportunity and flexibility to explore new information, ideas, and questions. These templates are easily transferred into an electronic journal (termed the E-notebook) and form the basic structural framework of the final lab reports the students submit electronically, via a learning management system. The guided-inquiry based approach presented here uses a single laboratory activity for undergraduate Introductory Biochemistry as an example. After implementation of this guided learning approach student surveys reported a higher level of course satisfaction and there was a statistically significant improvement in the quality of the student work. Therefore we firmly believe the described format to be highly effective in promoting student learning and engagement. © 2013 by The International Union of Biochemistry and Molecular Biology.

Implicit sequence-specific motor learning after sub-cortical stroke is associated with increased prefrontal brain activations: An fMRI study

Implicit motor learning is preserved after stroke, but how the brain compensates for damage to facilitate learning is unclear. We used a random effects analysis to determine how stroke alters patterns of brain activity during implicit sequence-specific motor learning as compared to general improvements in motor control. Nine healthy participants and 9 individuals with chronic, right focal sub-cortical stroke performed a continuous joystick-based tracking task during an initial fMRI session, over 5 days of practice, and a retention test during a separate fMRI session. Sequence-specific implicit motor learning was differentiated from general improvements in motor control by comparing tracking performance on a novel, repeated tracking sequences during early practice and again at the retention test. Both groups demonstrated implicit sequence-specific motor learning at the retention test, yet substantial differences were apparent. At retention, healthy control participants demonstrated increased BOLD response in left dorsal premotor cortex (BA 6) but decreased BOLD response left dorsolateral prefrontal cortex (DLPFC; BA 9) during repeated sequence tracking. In contrast, at retention individuals with stroke did not show this reduction in DLPFC during repeated tracking. Instead implicit sequence-specific motor learning and general improvements in motor control were associated with increased BOLD response in the left middle frontal gyrus BA 8, regardless of sequence type after stroke. These data emphasize the potential importance of a prefrontal-based attentional network for implicit motor learning after stroke. The present study is the first to highlight the importance of the prefrontal cortex for implicit sequence-specific motor learning after stroke. PMID:20725908

Associative learning rapidly establishes neuronal representations of upcoming behavioral choices in crows

Veit, Lena; Pidpruzhnykova, Galyna; Nieder, Andreas

2015-01-01

The ability to form associations between behaviorally relevant sensory stimuli is fundamental for goal-directed behaviors. We investigated neuronal activity in the telencephalic area nidopallium caudolaterale (NCL) while two crows (Corvus corone) performed a delayed association task. Whereas some paired associates were familiar to the crows, novel associations had to be learned and mapped to the same target stimuli within a single session. We found neurons that prospectively encoded the chosen test item during the delay for both familiar and newly learned associations. These neurons increased their selectivity during learning in parallel with the crows' increased behavioral performance. Thus, sustained activity in the NCL actively processes information for the upcoming behavioral choice. These data provide new insights into memory representations of behaviorally meaningful stimuli in birds, and how such representations are formed during learning. The findings suggest that the NCL plays a role in learning arbitrary associations, a cornerstone of corvids’ remarkable behavioral flexibility and adaptability. PMID:26598669

Past didactic pedagogy on biomedical research ethics and informed consent in our program had resulted in passive memorization of information and disengaged learning within psychiatry residents and clinical researchers. The question is how do we better motivate and engage learners within the session. Thus, we incorporated narratives into the learning environment and hypothesised that the use of narratives in the teaching of biomedical research ethics and informed consent would be associated with greater engagement, motivation, understanding, reflective learning and effectiveness of the teaching session. The narratives were chosen from the history of research ethics and the humanities literature related to human subject research. Learners were asked to provide post-session feedback through an anonymised questionnaire on their learning session. An outcomes logic model was used for assessment with focus on immediate outcomes such as engagement, motivation, understanding and reflective learning. Overall, 70.5% (N = 273) of the learners responded to the questionnaire. Amongst the respondents, 92.6% (N = 253) of the participants ranked use of narratives as most helpful in appreciating the historical context of research ethics and informed consent in research. The majority felt engaged (89.8%, N = 245), more motivated to learn (77.5%, N = 212) and better equipped (86.4%, N = 236) about the subject matter. Better appreciation of the learning topic, engagement, motivation to learn, equipping were strongly correlated with the promotion of reflective learning, effectiveness of teaching, promotion of critical thinking and overall positive rating of the teaching session on research ethics (all p < 0.001). Multivariate analyses found that the use of narratives was associated with higher overall rating of the teaching session (p = 0.003) and promotion of critical thinking (p = 0.02). Results revealed that the use of narratives could enhance engagement, appreciation of biomedical research ethics and informed consent, and address underlying motivational factors behind learning and understanding of research ethics.

Persistence of improvements in postural strategies following motor control training in people with recurrent low back pain.

Tsao, Henry; Hodges, Paul W

2008-08-01

This study investigated long-term effects of training on postural control using the model of deficits in activation of transversus abdominis (TrA) in people with recurrent low back pain (LBP). Nine volunteers with LBP attended four sessions for assessment and/or training (initial, two weeks, four weeks and six months). Training of repeated isolated voluntary TrA contractions were performed at the initial and two-week session with feedback from real-time ultrasound imaging. Home program involved training twice daily for four weeks. Electromyographic activity (EMG) of trunk and deltoid muscles was recorded with surface and fine-wire electrodes. Rapid arm movement and walking were performed at each session, and immediately after training on the first two sessions. Onset of trunk muscle activation relative to prime mover deltoid during arm movements, and the coefficient of variation (CV) of EMG during averaged gait cycle were calculated. Over four weeks of training, onset of TrA EMG was earlier during arm movements and CV of TrA EMG was reduced (consistent with more sustained EMG activity). Changes were retained at six months follow-up (p<0.05). These results show persistence of motor control changes following training and demonstrate that this training approach leads to motor learning of automatic postural control strategies.

Lymnaea stagnalis is a well-studied model system for determining how changes in the environment influence associative learning and memory formation. For example, some wild strains of L. stagnalis , collected from separate geographic locations, show superior memory-forming abilities compared with others. Here, we studied memory formation in two laboratory-bred L. stagnalis strains, derived from the same original population in The Netherlands. The two strains were reared in two different laboratories at the University of Calgary (C-strain) and at Brock University (B-strain) for many years and we found that they differed in their memory-forming ability. Specifically, the C-strain required only two training sessions to form long-term memory (LTM) whereas the B-strain required four sessions to form LTM. Additionally, the LTM formed by the B-strain persisted for a shorter amount of time than the memory formed by the C-strain. Thus, despite being derived from the same original population, the C- and B-strains have developed different memory-forming abilities. Next, we raised the two strains from embryos away from home (i.e. in the other laboratory) over two generations and assessed their memory-forming abilities. The B-strain reared and maintained at the University of Calgary demonstrated improved memory-forming ability within a single generation, while the C-strain reared at Brock University retained their normal LTM-forming ability across two subsequent generations. This suggests that local environmental factors may contribute to the behavioural divergence observed between these two laboratory-bred strains. © 2018. Published by The Company of Biologists Ltd.

To help university teachers to understand Service-Learning and develop Service-Learning subjects, a 3-h+ e-learning package was developed at The Hong Kong Polytechnic University (PolyU). There are seven units in this e-learning package: introduction session (Unit 1), what is Service-Learning? (Unit 2), impact and benefits of Service-Learning (Unit 3), myths and positive attitudes toward Service-Learning (Unit 4), developing a Service-Learning subject at PolyU (Unit 5), self-reflection about Service-Learning (Unit 6), and concluding session (Unit 7). To understand the views of the users on the e-learning package, the package was offered before formal launching. For the first offering, three focus group sessions were held. Results showed that the users were satisfied with the structural arrangement of the e-learning package and agreed that the e-learning package was useful for them to understand more about Service-Learning. For the second offering, colleagues were generally satisfied with the e-learning package and demonstrated gain in knowledge on Service-Learning. Suggestions for improvement were noted.

Flipping the classroom centres on the delivery of print, audio or video based material prior to a lecture or class session. The class session is then dedicated to more active learning processes with application of knowledge through problem solving or case based scenarios. The rationale behind this approach is that teachers can spend their face-to-face time supporting students in deeper learning processes. In this paper we provide a background literature review on the flipped classroom along with a three step approach to flipping the classroom comprising implementing, enacting and evaluating this form of pedagogy. Our three step approach is based on actual experience of delivering a flipped classroom at the University of Hong Kong. This initiative was evaluated with positive results. We hope our experience will be transferable to other medical institutions.

Evaluation of the role of incentive structure on student participation and performance in active learning strategies: A comparison of case-based and team-based learning.

PubMed

Carrasco, Gonzalo A; Behling, Kathryn C; Lopez, Osvaldo J

2018-04-01

Student participation is important for the success of active learning strategies, but participation is often linked to the level of preparation. At our institution, we use two types of active learning activities, a modified case-based learning exercise called active learning groups (ALG) and team-based learning (TBL). These strategies have different assessment and incentive structures for participation. Non-cognitive skills are assessed in ALG using a subjective five-point Likert scale. In TBL, assessment of individual student preparation is based on a multiple choice quiz conducted at the beginning of each session. We studied first-year medical student participation and performance in ALG and TBL as well as performance on course final examinations. Student performance in TBL, but not in ALG, was strongly correlated with final examination scores. Additionally, in students who performed in the upper 33rd percentile on the final examination, there was a positive correlation between final examination performance and participation in TBL and ALG. This correlation was not seen in students who performed in the lower 33rd percentile on the final examinations. Our results suggest that assessments of medical knowledge during active learning exercises could supplement non-cognitive assessments and could be good predictors of performance on summative examinations.

The integrity of the rodent anterior cingulate cortex (ACC) is essential for various aspects of instrumental behavior, but it is not clear if the ACC is important for the acquisition of a simple instrumental response. Here, it was demonstrated that post-session infusions of anisomycin into the rat ACC completely prevented the acquisition of instrumental responding. The experimental use of post-session intracranial infusions of plasticity inhibitors is assumed to affect local consolidation of plasticity, but not behavioral task performance. However, in associative appetitive conditioning, post-session intracranial infusion of pharmaco-active compounds could actually interfere with subsequent task performance indirectly through retrospective effects on the valuation of ingested rewards. Thus, it was subsequently demonstrated that the intracranial infusion of anisomycin into the ACC after sucrose pellet consumption significantly reduced subsequent pellet consumption, suggesting that the infusion of anisomycin into the ACC produced conditioned taste avoidance. In the third experiment, an innovative procedure was introduced that dissociated the effects of intracranial infusions after conditioning sessions on task-learning and unconditioned stimulus valuation. With this procedure, the infusion of anisomycin into the ACC after instrumental sessions did not affect instrumental reinforcer valuation or the acquisition of instrumental responding, suggesting that plasticity in the ACC is not necessary for the acquisition of instrumental behavior.

Optimisation of simulated team training through the application of learning theories: a debate for a conceptual framework

PubMed Central

2014-01-01

Background As a conceptual review, this paper will debate relevant learning theories to inform the development, design and delivery of an effective educational programme for simulated team training relevant to health professionals. Discussion Kolb’s experiential learning theory is used as the main conceptual framework to define the sequence of activities. Dewey’s theory of reflective thought and action, Jarvis modification of Kolb’s learning cycle and Schön’s reflection-on-action serve as a model to design scenarios for optimal concrete experience and debriefing for challenging participants’ beliefs and habits. Bandura’s theory of self-efficacy and newer socio-cultural learning models outline that for efficient team training, it is mandatory to introduce the social-cultural context of a team. Summary The ideal simulated team training programme needs a scenario for concrete experience, followed by a debriefing with a critical reflexive observation and abstract conceptualisation phase, and ending with a second scenario for active experimentation. Let them re-experiment to optimise the effect of a simulated training session. Challenge them to the edge: The scenario needs to challenge participants to generate failures and feelings of inadequacy to drive and motivate team members to critical reflect and learn. Not experience itself but the inadequacy and contradictions of habitual experience serve as basis for reflection. Facilitate critical reflection: Facilitators and group members must guide and motivate individual participants through the debriefing session, inciting and empowering learners to challenge their own beliefs and habits. To do this, learners need to feel psychological safe. Let the group talk and critical explore. Motivate with reality and context: Training with multidisciplinary team members, with different levels of expertise, acting in their usual environment (in-situ simulation) on physiological variables is mandatory to introduce cultural context and social conditions to the learning experience. Embedding in situ team training sessions into a teaching programme to enable repeated training and to assess regularly team performance is mandatory for a cultural change of sustained improvement of team performance and patient safety.

Does arousal interfere with operant conditioning of spike-wave discharges in genetic epileptic rats?

PubMed

Osterhagen, Lasse; Breteler, Marinus; van Luijtelaar, Gilles

2010-06-01

One of the ways in which brain computer interfaces can be used is neurofeedback (NF). Subjects use their brain activation to control an external device, and with this technique it is also possible to learn to control aspects of the brain activity by operant conditioning. Beneficial effects of NF training on seizure occurrence have been described in epileptic patients. Little research has been done about differentiating NF effectiveness by type of epilepsy, particularly, whether idiopathic generalized seizures are susceptible to NF. In this experiment, seizures that manifest themselves as spike-wave discharges (SWDs) in the EEG were reinforced during 10 sessions in 6 rats of the WAG/Rij strain, an animal model for absence epilepsy. EEG's were recorded before and after the training sessions. Reinforcing SWDs let to decreased SWD occurrences during training; however, the changes during training were not persistent in the post-training sessions. Because behavioural states are known to have an influence on the occurrence of SWDs, it is proposed that the reinforcement situation increased arousal which resulted in fewer SWDs. Additional tests supported this hypothesis. The outcomes have implications for the possibility to train SWDs with operant learning techniques. Copyright (c) 2010 Elsevier B.V. All rights reserved.

Role-play for medical students learning about communication: Guidelines for maximising benefits

Nestel, Debra; Tierney, Tanya

2007-01-01

Background Role-play is widely used as an educational method for learning about communication in medical education. Although educational theory provides a sound rationale for using this form of simulation, there is little published evidence for its effectiveness. Students' prior experiences of role-play may influence the way in which they engage in this method. This paper explores students' experiences with the aim of producing guidelines for maximising the benefits of role-play within this learning context. Methods First-year undergraduate medical students participated in a role-play session as part of their communication programme. Before and after the session, students completed questionnaires. In the pre-session questionnaire, students were asked about their experiences of role-play and asked to identify helpful and unhelpful elements. Immediately after the session, students answered similar questions in relation to the role-play activity they had just completed. Descriptive statistics were used to analyse quantitative data and qualitative data was thematically analysed. Results 284 students completed evaluation forms. Although 63 (22.2%) had prior unhelpful experiences, most students (n = 274; 96.5%) found this experience helpful. Summary findings were that students reported the key aspects of helpful role-play were opportunities for observation, rehearsal and discussion, realistic roles and alignment of roles with other aspects of the curriculum. Unhelpful aspects were those that evoked strong negative emotional responses and factors that contributed to a lack of realism. Conclusion Role-play was valued by students in the acquisition of communication skills even though some had prior unhelpful experiences. Guidelines for effective role-play include adequate preparation, alignment of roles and tasks with level of practice, structured feedback guidelines and acknowledgment of the importance of social interactions for learning.

The present study assessed the possibility of assisting four persons with multiple disabilities to move through and perform simple occupational activities arranged within a room with the help of automatic prompting. The study involved two multiple probe designs across participants. The first multiple probe concerned the two participants with blindness or minimal vision and deafness, who received air blowing as a prompt. The second multiple probe concerned the two participants with blindness and typical hearing who received a voice calling as a prompt. Initially, all participants had baseline sessions. Then intervention started with the first participant of each dyad. When their performance was consolidated, new baseline and intervention occurred with the second participant of each dyad. Finally, all four participants were exposed to a second intervention phase, in which the number of activities per session doubled (i.e., from 8 to 16). Data showed that all four participants: (a) learned to move across and perform the activities available with the help of automatic prompting and (b) remained highly successful through the second intervention phase when the sessions were extended. Implications of the findings are discussed.

RealTime Physics: Active learning laboratory

Our research shows that student learning of physics concepts in introductory physics courses is enhanced by the use of special guided discovery laboratory curricula which embody the results of educational research and which are supported by the use of the Tools for Scientific Thinking microcomputer-based laboratory (MBL) tools. In this paper we first describe the general characteristics of the research-based RealTime Physics laboratory curricula developed for use in introductory physics classes in colleges, universities and high schools. We then describe RealTime Physics Mechanics in detail. Finally we examine student learning of dynamics in traditional physics courses and in courses using RealTime Physics Mechanics, primarily by the use of correlated questions on the Force and Motion Conceptual Evaluation. We present considerable evidence that students who use the new laboratory curricula demonstrate significantly improved learning and retention of dynamics concepts compared to students taught by traditional methods.

In this session, we discuss different approaches to reaching large audiences. In addition to star parties and astronomy events, the audiences for some of the events include music concerts or festivals, sick children and their families, minority communities, American Indian reservations, and tourist sites such as the National Mall. The goal is to bring science directly to the public—to people who attend astronomy events and to people who do not come to star parties, science museums, or science festivals. These programs allow the entire community to participate in astronomy activities to enhance the public appreciation of science. These programs attract large enthusiastic crowds often with young children participating in these family learning experiences. The public will become more informed, educated, and inspired about astronomy and will also be provided with information that will allow them to continue to learn after this outreach activity. Large and unique audiences often have common problems, and their solutions and the lessons learned will be presented. Interaction with the participants in this session will provide important community feedback used to improve astronomy outreach for large and unique audiences. New ways to expand astronomy outreach to new large audiences will be discussed.

Combining traditional anatomy lectures with e-learning activities: how do students perceive their learning experience?

2016-02-21

The purpose of this study was to investigate how students perceived their learning experience when combining traditional anatomy lectures with preparatory e-learning activities that consisted of fill-in-the-blank assignments, videos, and multiple-choice quizzes. A qualitative study was conducted to explore changes in study behaviour and perception of learning. Three group interviews with students were conducted and thematically analysed. Data was categorized into four themes: 1. Approaching the course material, 2. Understanding the material, 3. Consolidating the material, and 4. Perceived learning outcome. Students appreciated the clear structure of the course, and reported that online activities encouraged them towards a first engagement with the material. They felt that they were more active during in-class sessions, described self-study before the end-of-term exam as easier, and believed that contents would remain in their memories for a longer time. By adjusting already existing resources, lectures can be combined fairly easily and cost-effectively with preparatory e-learning activities. The creation of online components promote well-structured courses, can help minimize 'student passivity' as a characteristic element of lectures, and can support students in distributing their studies throughout the term, thus suggesting enhanced learning. Further research work should be designed to confirm the afore-mentioned findings through objective measurements of student learning outcomes.

2009-01-01

The aim of this study was to investigate the attitudes of veterinary science students to activities designed to promote curriculum integration. Students (N = 33) in their second year of a five-year veterinary degree were surveyed in regard to their attitudes to activities that aimed to promote integration. Imaging, veterinary practice practicals, and a field trip to a cattle property were classified as the three most valuable learning activities that were designed to promote integration. Veterinary practice practicals, case studies, and palpable anatomy were regarded by students as helping them to learn information presented in other teaching sessions. They also appeared to enhance student motivation, and students indicated that the activities assisted them with their preparation for and performance at examinations. Attitudes to whether the learning exercises helped improve a range of skills and specific knowledge varied, with 39-88% of students agreeing that specific skills and knowledge were enhanced to a large or very large extent by the learning activities. The results indicate that learning activities designed to promote curriculum integration helped improve motivation, reinforced learning, created links between foundational knowledge and its application, and assisted with the development of skills that are related to what students will do in their future careers.

[Activity of Retrosplenial Neurons during the First Days and after a Week Following the Learning of the Operant Food-Acquisition Task].

PubMed

Kuzina, E A; Gorkin, A G; Alexandrov, I

2015-01-01

Activity of single neurons in the retrosplenial cortex of rats during realization of the operant food-acquisition behavior was recorded. In the first group of rats the recordings were made in the first six days after learning of the task and in the second group--following a week of a rest after learning. There were no significant differences in proportion of neurons specialized in relation to the learned behavior; however in the first group 40% of these cells had specific activations only in 80-90%, but not in all (100%) realizations of their specific behavioral acts, while in the second group there were much less relative numbers (4%) of such cells. All neurons with not-100% activations on the early stages after the learning were specialized in relation to acts of approaching and pressing the pedal that rats acquired on the last session of learning. It could be supposed that during the first stages of consolidation of the operant skill some variable set of retrosplenial cortex neurons specialized to new behavioral acts can be involved.

Video Observation as a Tool to Analyze and Modify an Electronics Laboratory

2016-12-01

Laboratories are an important part of science and engineering education, especially in the field of electronics. Yet very little research into the benefits of such labs to student learning exists. In particular, it is not well known what students do and, even more importantly, think during electronics laboratories. Therefore, we conducted a study based on video observation of second year students at 3 university campuses in Belgium during a traditional lab on first order R C filters. In this laboratory, students spent the majority of their time performing measurements, while very little time was spent processing or discussing the results. This in turn resulted in hardly any time spent talking about content knowledge. Based on those observations, a new laboratory was designed that includes a preparation with a virtual oscilloscope, a black box approach during the lab session itself, and a form of quick reporting at the end of the lab. This adjusted laboratory was evaluated using the same methodology and was more successful in the sense that the students spent less time gathering measurements and more time processing and analyzing them, resulting in more content-based discussion.

Unifying practice schedules in the timescales of motor learning and performance.

PubMed

Verhoeven, F Martijn; Newell, Karl M

2018-06-01

In this article, we elaborate from a multiple time scales model of motor learning to examine the independent and integrated effects of massed and distributed practice schedules within- and between-sessions on the persistent (learning) and transient (warm-up, fatigue) processes of performance change. The timescales framework reveals the influence of practice distribution on four learning-related processes: the persistent processes of learning and forgetting, and the transient processes of warm-up decrement and fatigue. The superposition of the different processes of practice leads to a unified set of effects for massed and distributed practice within- and between-sessions in learning motor tasks. This analysis of the interaction between the duration of the interval of practice trials or sessions and parameters of the introduced time scale model captures the unified influence of the between trial and session scheduling of practice on learning and performance. It provides a starting point for new theoretically based hypotheses, and the scheduling of practice that minimizes the negative effects of warm-up decrement, fatigue and forgetting while exploiting the positive effects of learning and retention.

Collaborative Reflection Under the Microscope: Using Conversation Analysis to Study the Transition From Case Presentation to Discussion in GP Residents' Experience Sharing Sessions.

PubMed

Veen, Mario; de la Croix, Anne

2016-01-01

PHENOMENON: In higher education, reflection sessions are often used when participants learn in the workplace. In the Netherlands, all General Practitioner training programs include regular meetings called Exchange of Experiences, in which General Practitioner trainees are expected to learn collaboratively from their own and one another's experiences. Despite this being common practice, we found little research into the structure and process of these sessions. The purpose of this study is to describe the structure and characteristics of group reflection by describing transitions in interactions. We aim to describe the tutor's role in some detail, as this could lead to faculty development. In medical education, reflection is often approached from a cognitive perspective. However, learning in a group is also an interactional achievement. It is therefore relevant to study the sequential nature of group interaction in collaborative reflective practice. We have used conversation analysis to study the reflection meetings, zooming in on the transition between case presentation and discussion, focusing on the role of each of the participants in these transitions. The transitions were conversationally complex. Three interactional aspects recurred in the meetings. First, the transitions can be characterized as ambiguous, as there is ambiguity about what will happen next and the floor is open. Second, transitions are an arena for negotiations between case presenter, participants, and tutors, in which knowledge and the right to take the floor (epistemics) play an important part. Third, the tutor can have different interactional roles, namely, that of teacher, expert, facilitator, and active participant. The role of the tutor is important as the tutor's interactional behavior is part of the hidden curriculum. Insights: Conversation analysis focuses on the interaction in group learning and shows how the interaction is part of what is learned and how learning takes place. Transitions are the "messy" moments in interaction yet can tell a lot about the way in which group participants relate to one another. Being conscious of how the floor is taken, the tutor's roles, and the way negotiations take place could help medical educators in the way they shape collaborative learning sessions.

Establishing the minimal number of virtual reality simulator training sessions necessary to develop basic laparoscopic skills competence: evaluation of the learning curve.

2013-01-01

Medical literature is scarce on information to define a basic skills training program for laparoscopic surgery (peg and transferring, cutting, clipping). The aim of this study was to determine the minimal number of simulator sessions of basic laparoscopic tasks necessary to elaborate an optimal virtual reality training curriculum. Eleven medical students with no previous laparoscopic experience were spontaneously enrolled. They were submitted to simulator training sessions starting at level 1 (Immersion Lap VR, San Jose, CA), including sequentially camera handling, peg and transfer, clipping and cutting. Each student trained twice a week until 10 sessions were completed. The score indexes were registered and analyzed. The total of errors of the evaluation sequences (camera, peg and transfer, clipping and cutting) were computed and thereafter, they were correlated to the total of items evaluated in each step, resulting in a success percent ratio for each student for each set of each completed session. Thereafter, we computed the cumulative success rate in 10 sessions, obtaining an analysis of the learning process. By non-linear regression the learning curve was analyzed. By the non-linear regression method the learning curve was analyzed and a r2 = 0.73 (p < 0.001) was obtained, being necessary 4.26 (∼five sessions) to reach the plateau of 80% of the estimated acquired knowledge, being that 100% of the students have reached this level of skills. From the fifth session till the 10th, the gain of knowledge was not significant, although some students reached 96% of the expected improvement. This study revealed that after five simulator training sequential sessions the students' learning curve reaches a plateau. The forward sessions in the same difficult level do not promote any improvement in laparoscopic basic surgical skills, and the students should be introduced to a more difficult training tasks level.

To evaluate the use of LabTutor (a physiological data capture and e-learning package) in bioscience education for student nurses. Knowledge of biosciences is important for nurses the world over, who have to monitor and assess their patient's clinical condition, and interpret that information to determine the most appropriate course of action. Nursing students have long been known to find acquiring useable bioscience knowledge challenging. Blended learning strategies are common in bioscience teaching to address the difficulties students have. Student nurses have a preference for hands-on learning, small group sessions and are helped by close juxtaposition of theory and practice. An evaluation of a new teaching method using in-classroom voluntary questionnaire. A structured survey instrument including statements and visual analogue response format and open questions was given to students who participated in Labtutor sessions. The students provided feedback in about the equipment, the learning and the session itself. First year (n = 93) and third year (n = 36) students completed the evaluation forms. The majority of students were confident about the equipment and using it to learn although a few felt anxious about computer-based learning. They all found the equipment helpful as part of their bioscience education and they all enjoyed the sessions. This equipment provides a helpful way to encourage guided independent learning through practice and discovery and because each session is case study based and the relationship of the data to the patient is made clear. Our students helped to evaluate our initial use of LabTutor and found the sessions enjoyable and helpful. LabTutor provides an effective learning tool as part of a blended learning strategy for biosciences teaching. Improving bioscience knowledge will lead to a greater understanding of pathophysiology, treatments and interventions and monitoring. © 2016 John Wiley & Sons Ltd.

Neural Basis of Working Memory Enhancement after Acute Aerobic Exercise: fMRI Study of Preadolescent Children.

Chen, Ai-Guo; Zhu, Li-Na; Yan, Jun; Yin, Heng-Chan

2016-01-01

Working memory lies at the core of cognitive function and plays a crucial role in children's learning, reasoning, problem solving, and intellectual activity. Behavioral findings have suggested that acute aerobic exercise improves children's working memory; however, there is still very little knowledge about whether a single session of aerobic exercise can alter working memory's brain activation patterns, as assessed by functional magnetic resonance imaging (fMRI). Therefore, we investigated the effect of acute moderate-intensity aerobic exercise on working memory and its brain activation patterns in preadolescent children, and further explored the neural basis of acute aerobic exercise on working memory in these children. We used a within-subjects design with a counterbalanced order. Nine healthy, right-handed children were scanned with a Siemens MAGNETOM Trio 3.0 Tesla magnetic resonance imaging scanner while they performed a working memory task (N-back task), following a baseline session and a 30-min, moderate-intensity exercise session. Compared with the baseline session, acute moderate-intensity aerobic exercise benefitted performance in the N-back task, increasing brain activities of bilateral parietal cortices, left hippocampus, and the bilateral cerebellum. These data extend the current knowledge by indicating that acute aerobic exercise enhances children's working memory, and the neural basis may be related to changes in the working memory's brain activation patterns elicited by acute aerobic exercise.

Active-learning strategies are increasingly being integrated into college-level science courses to make material more accessible to all students and to improve learning outcomes. One active-learning pedagogy, case-based learning (CBL), was developed as a way to both enhance engagement in the material and to accommodate diverse learning styles. Yet, adoption of CBL approaches in undergraduate biology courses has been piecemeal, in part because of the perceived investment of time required. Furthermore, few CBL lesson plans have been developed specifically for upper-division laboratory courses. Here, we describe four cases that we developed and implemented for a senior cell and molecular biology laboratory course at San Francisco State University, a minority-serving institution. To evaluate the effectiveness of these modules, we used both written and verbal assessments to gauge learning outcomes and attitudinal responses of students over two semesters. Students responded positively to the new approach and seemed to meet the learning goals for the course. Most said they would take a course using CBL again. These case modules are readily adaptable to a variety of classroom settings.

Active-learning strategies are increasingly being integrated into college-level science courses to make material more accessible to all students and to improve learning outcomes. One active-learning pedagogy, case-based learning (CBL), was developed as a way to both enhance engagement in the material and to accommodate diverse learning styles. Yet, adoption of CBL approaches in undergraduate biology courses has been piecemeal, in part because of the perceived investment of time required. Furthermore, few CBL lesson plans have been developed specifically for upper-division laboratory courses. Here, we describe four cases that we developed and implemented for a senior cell and molecular biology laboratory course at San Francisco State University, a minority-serving institution. To evaluate the effectiveness of these modules, we used both written and verbal assessments to gauge learning outcomes and attitudinal responses of students over two semesters. Students responded positively to the new approach and seemed to meet the learning goals for the course. Most said they would take a course using CBL again. These case modules are readily adaptable to a variety of classroom settings. PMID:19047425

Rethinking how Undergraduate ``Hard Rock'' Petrology is Taught

A course in "hard rock" petrology forms a core component of undergraduate training in the geosciences. In most cases, the subjects of igneous and metamorphic petrology are combined in a single course and the course is traditionally structured so that the two subjects are covered in series. This approach enables students to focus on each subject separately, with knowledge of igneous rocks helping students to understand metamorphic rock protoliths. Student assessment shows, however, that this approach tends to compartmentalize learning and the two main subjects might just as well be taught in separate courses. In practical applications such as fieldwork, students must be able to access their understanding of igneous and metamorphic rocks virtually simultaneously. To better integrate student learning, I developed a spiral learning approach to teaching petrology (e.g., Bruner, 1990; Dyar et al., 2004) so that commonalities could be revisited several times over the course of a semester and, in so doing, students' grasp of the fundamental insights provided by igneous and metamorphic rocks could be scaffolded into greater understanding. The course initially focuses on the dynamics of the environments in which igneous and metamorphic rocks form: heat flow, fluid flow, and plate tectonics. Several subsequent weeks explore topics relevant to identifying and understanding igneous and metamorphic rocks in the field: crystal nucleation and growth, the roles of pressure and heat, and field classification. Laboratory exercises parallel this structure, also emphasizing observations that are valuable in the field: the relationship between minerals and rocks, textural observations, and general rock classification. The final portion of the course explores “hard rocks” in more detail with a greater emphasis on the interplay between chemistry and mineralogy. A variety of learner-centered activities in the course help students bridge the gap between novice and expert and include more explicit emphasis on visualization and on helping students become comfortable with interpreting data numerically and graphically. Pen tablet computers are used extensively in the laboratory for visualization, photomicrograph capture, and annotation. Cooperative learning activities developed for this course make use of learning methods such as pair share, round-robin, small group explorations case studies, and jigsaw exercises (sometimes as introduction to, sometimes as review of material), and Jeopardy-style review sessions. On an assessment questionnaire at the end of the semester students ranked the in-class cooperative learning activities as on par with lectures and homework exercises in facilitating their learning. Students reported satisfactory attainment of three major goals identified for the course even though they were not explicitly reminded of these goals at the time of assessment.

Technology in the teaching of neuroscience: enhanced student learning.

The primary motivation for integrating any form of education technology into a particular course or curriculum should always be to enhance student learning. However, it can be difficult to determine which technologies will be the most appropriate and effective teaching tools. Through the alignment of technology-enhanced learning experiences with a clear set of learning objectives, teaching becomes more efficient and effective and learning is truly enhanced. In this article, I describe how I have made extensive use of technology in two neuroscience courses that differ in structure and content. Course websites function as resource centers and provide a forum for student interaction. PowerPoint presentations enhance formal lectures and provide an organized outline of presented material. Some lectures are also supplemented with interactive CD-ROMs, used in the presentation of difficult physiological concepts. In addition, a computer-based physiological recording system is used in laboratory sessions, improving the hands-on experience of group learning while reinforcing the concepts of the research method. Although technology can provide powerful teaching tools, the enhancement of the learning environment is still dependent on the instructor. It is the skill and enthusiasm of the instructor that determines whether technology will be used effectively.

Effective management of chronic diseases (e.g., diabetes) can depend on the extent to which patients can learn and remember disease-relevant information. In two experiments, we explored a technique motivated by theories of self-regulated learning for improving people's learning of information relevant to managing a chronic disease. Materials were passages from patient education booklets on diabetes from NIDDK. Session 1 included an initial study trial, Session 2 included self-regulated restudy, and Session 3 included a final memory test. The key manipulation concerned the kind of support provided for self-regulated learning during Session 2. In Experiment 1, participants either were prompted to self-test and then evaluate their learning before selecting passages to restudy, were shown the prompt questions but did not overtly self-test or evaluate learning prior to selecting passages, or were not shown any prompts and were simply given the menu for selecting passages to restudy. Participants who self-tested and evaluated learning during Session 2 had a small but significant advantage over the other groups on the final test. Secondary analyses provided evidence that the performance advantage may have been modest because of inaccurate monitoring. Experiment 2 included a group who also self-tested but who evaluated their learning using idea-unit judgments (i.e., by checking their responses against a list of key ideas from the correct response). Participants who self-tested and made idea-unit judgments exhibited a sizable advantage on final test performance. Secondary analyses indicated that the performance advantage was attributable in part to more accurate monitoring and more effective self-regulated learning. An important practical implication is that learning of patient education materials can be enhanced by including appropriate support for learners' self-regulatory processes.
