The aim of this study was to assess the perceived benefits of video-mediated demonstrations in learning endodontics. Participants in the study were 75 third-year students enrolled in the undergraduate dentistry program at Karolinska Institute, Stockholm, Sweden. After the endodontic preclinical course, the students were introduced to the treatment protocol in the clinic by watching two live patient-demonstrated videos. The first video demonstrated how to communicate with the patient and perform diagnosis and root canal instrumentation. The second video illustrated how to perform bacterial sampling and root canal filling. After the students watched each video, a questionnaire was used to evaluate their opinions about various steps of the endodontic treatment protocol and the benefit of such educational material for their practice. Of the total 75 students, 72 completed the first questionnaire (96% response rate), and 65 completed the second questionnaire (87% response rate). The results showed that the students perceived high value in the video demonstrations related to treatment procedure. A statistically significant difference was observed between the perceived benefits of the first and second sessions in communication and treatment procedure (p<0.001). Further studies are needed to assess improvement in the design and delivery format for video demonstrations to enhance their effectiveness as a teaching modality for endodontics.

It is quite difficult to teach complex topics like the physiology of vestibular apparatus to undergraduate students. Understanding the orientation and mode of stimulation of receptors in vestibular apparatus is also quite challenging for the students. As faculty we attempt to use innovative methods to teach physiology and enhance student learning. This article describes a simple and innovative method (student-involved demonstration approach, or SID) to teach the physiology of the vestibular apparatus to the undergraduate medical students. The current study describes a protocol where students engage in role-play sessions in the middle of the regular didactic lectures. Effectiveness of the sessions was later evaluated by using a questionnaire and by comparing the pre-SID and post-SID test results of the students. The posttest score of the students was significantly higher than the pretest score, and this indicates the usefulness of SID sessions on enhancing the student learning in the class. Students also found this method very interesting and useful in better understanding the physiology of the vestibular apparatus.

Improving Web-Based Student Learning Through Online Video Demonstrations

Students in online courses continue to lag their peers in comparable face-to-face (F2F) courses (Ury 2004, Slater & Jones 2004). A meta-study of web-based vs. classroom instruction by Sitzmann et al (2006) discovered that the degree of learner control positively influences the effectiveness of instruction: students do better when they are in control of their own learning. In particular, web-based courses are more effective when they incorporate a larger variety of instructional methods. To address this need, we developed a series of online videos to demonstrate various astronomical concepts and provided them to students enrolled in an online introductory astronomy course at Penn State University. We found that the online students performed worse than the F2F students on questions unrelated to the videos (t = -2.84), but that the online students who watched the videos performed better than the F2F students on related examination questions (t = 2.11). We also found that the online students who watched the videos performed significantly better than those who did not (t = 3.43). While the videos in general proved helpful, some videos were more helpful than others. We will discuss our thoughts on why this might be, and future plans to improve upon this study. These videos are freely available on iTunesU, YouTube, and Google Video.

This study used role-play demonstrations to train medical students to communicate drug therapy and evaluated the perceptions on this instructional approach. The second-year medical students who attended a prescription writing session (n = 133), participated in this study. Prescription communication was introduced by using role-play demonstrations. Participant's perceptions were explored by a self-administered questionnaire and focus group discussion. The academic achievement of attendees and nonattendees was compared with an objective structured performance evaluation (OSPE) station that tested students' competence in this skill. Most attendees responded to the questionnaire (81.2%). Almost all respondents expressed their desire to have similar demonstrations in other units. A large proportion of participants reported that role-play demonstrations helped them develop their communication skills, in general, confidence to communicate drug-related information in a prescription, and the ability to explain the aim of drug therapy to patients. Most trainees thought also that they developed skills to communicate instructions on drug use including drug dose, frequency of administration, duration of therapy, adverse drug reactions, and warnings. During the focus group interviews, students thought that role-play was useful but would be more beneficial if conducted frequently in small group as part of the curriculum implementation. The majority of students also reported improved competence in writing a complete prescription. Analysis of attendees and nonattendees grades in the OSPE showed that the former scored higher than the latter group (P = 0.016). Role-play demonstrations were well accepted by medical students and led to the development of their competence in communicating drug therapy to patients.

Current health policy focuses on improving accessibility, increasing integration and shifting resources from hospitals to community and primary care. Initiatives aimed at achieving these policy aims have supported the implementation of various 'new models of care', including general practice offering 'additional availability' appointments during evenings and at weekends. In Greater Manchester, six 'demonstrator sites' were funded: four sites delivered additional availability appointments, other services included case management and rapid response. The aim of this paper is to explore the factors influencing the implementation of services within a programme designed to improve access to primary care. The paper consists of a qualitative process evaluation undertaken within provider organisations, including general practices, hospitals and care homes. Semi-structured interviews, with the data subjected to thematic analysis. Ninety-one people participated in interviews. Six key factors were identified as important for the establishment and running of the demonstrators: information technology; information governance; workforce and organisational development; communications and engagement; supporting infrastructure; federations and alliances. These factors brought to light challenges in the attempt to provide new or modify existing services. Underpinning all factors was the issue of trust; there was consensus amongst our participants that trusting relationships, particularly between general practices, were vital for collaboration. It was also crucial that general practices trusted in the integrity of anyone external who was to work with the practice, particularly if they were to access data on the practice computer system. A dialogical approach was required, which enabled staff to see themselves as active rather than passive participants. The research highlights various challenges presented by the context within which extended access is implemented. Trust was the

Anatomy is the fundamental of medical and health professional education. Anatomic dissection enables the examination of the organs in the human cadavers systematically and topographically. The aim of this study was to determine the effect of the first cadaver demonstration and the anxiety of medical, dental and pharmacy students. A questionnaire was distributed to 486 students in the same academic year (2009-2010) at Ege University. The review of anxiety reveals the circumstances such as exhaustion, stress, depression, anxiety, destructive life, deterioration of mental or physical quality or asthenia (over-fatigue), professionally having a serious effect on the students. 486 (85.3 %) students in total participated in this research carried out as based on voluntariness as 338 (93.9 %) students from the medical faculty, 78 (70.9 %) students from the faculty of dentistry and 70 (70 %) students from the faculty of pharmacy.A medium level of anxiety was detected in the students in their first encounter with the cadaver. The state anxiety score (SAS) average taken by all the students who took part in the research is 42.6 ± 5.60 and trait anxiety score average is 46.6 ± 5.0. No discrepancy was detected among the faculties with respect to anxiety score. While the SASs of the male students were higher than the girls, the trait anxiety scores of the girl students were detected to be higher than male students. While the characteristics and the cultural life of our society force the male students into stronger behavioral patterns, they may actually increase their anxiety level in distressed conditions. The fact that trait anxiety is high in both sexes, particularly in female students can be explained by the patient responsibility and the work load undertaken in the professions in the medical field as early as the period of education.Before the students' applied lessons with the cadavers start, a preparatory session must be planned for this education to decrease the

Scientists in academia often want to share their knowledge of and enthusiasm for science with K-12 students, but feel wary of the time commitment and logistical details involved with volunteer work. As a PhD student at UC Berkeley, I participated in the Community in the Classroom program, organized by the non-profit Community Resources for Science. CRS acts as the liaison between local schools and scientists in the community, taking care of all the administrative details regarding the classroom visits. Volunteers are asked to prepare a fun, hands-on presentation for a specific grade level, which is linked to elementary science standards. I chose to visit several fifth grade classrooms and talk about the connection between climate change and the water cycle in California. My presentation included a demonstration of the greenhouse effect, an experiment to see where the water on the outside of a cold glass comes from, and an investigation into the role of temperature in the phase changes of water, using plastic containers, icepacks and mitten warmers. The students were encouraged to make predictions about the impact of climate change on the water cycle based on their recent observations. I will share my demonstrations, discuss feedback from the students and teachers and offer suggestions to those interested in volunteer teaching.

Using discrepant events in science demonstrations to promote student engagement in scientific investigations: An action research study

NASA Astrophysics Data System (ADS)

Mancuso, Vincent J.

Students' scientific investigations have been identified in national standards and related reform documents as a critical component of students' learning experiences in school, yet it is not easy to implement them in science classrooms. Could science demonstrations help science teachers put this recommendation into practice? While demonstrations are a common practice in the science classroom and research has documented some positive effects in terms of student motivation and engagement from their use, the literature also shows that, as traditionally presented, science demonstrations do not always achieve their intended outcomes. This, in turn, suggested the value of investigating what design elements of demonstrations could be used to promote specific instructional goals. Employing action research as a methodology, the proposed study was developed to explore how science demonstrations can be designed so as to most effectively promote student engagement in scientific investigations. More specifically, I was interested in examining the effects of using a discrepant event as part of the demonstration, as a way to create cognitive conflict and, thus, increase interest and engagement. I also investigated the relative merit of the well-researched POE (Predict, Observe, Explain) design versus employing demonstrations that appear to the student to be unplanned (what I will refer to as NOE, or a Naturally Occurring Experience). This study was informed by Constructivism, Situated Cognition and Conceptual Change as theoretical frameworks. The project included the design, implementation and study of an intervention consisting of three instructional units designed to support students' learning of the concepts of density, molecular arrangement of gas particles, and cohesion, respectively. In each of these units, lasting a total of two 80-minute class periods, students were asked to design and conduct an investigation to gain a better understanding of the concept under study. In

Research has shown that the use of demonstrations and hands-on activities in the classroom enhances student learning. Students learn more and enjoy classes more when visual and active learning are incorporated into the lecture. Most college-aged students prefer visual modes of learning, while most instruction is conducted in a lecture, or auditory, format. The use of classroom demonstrations provides opportunities for incorporating visual and active learning into the classroom environment. However, while most instructors acknowledge the benefits of these teaching methods, they typically do not have the time and resources to develop and test such activities and to develop plans to incorporate them into their lectures. Members of the Excellence in Water Resources Education Task Committee of the Environmental and Water Resources Institute (EWRI) of the American Society of Civil Engineers (ASCE) have produced a publication that contains a collection of activities aimed to foster excellence in water resources and hydrology education and improve student learning of principles. The book contains forty-five demonstrations and activities that can be used in water-related classes with topics in fluid mechanics, hydraulics, surface water hydrology, groundwater hydrology, and water quality. We present examples of these activities, including topics such as conservation of momentum, buoyancy, Bernoulli's principle, drag force, pipe flow, watershed delineation, reservoir networks, head distribution in aquifers, and molecular diffusion in a porous medium. Unlike full laboratory exercises, these brief demonstrations and activities (most of which take less than fifteen minutes) can be easily incorporated into classroom lectures. For each demonstration, guidance for preparing and conducting the activity, along with a brief overview of the principles that are demonstrated, is provided. The target audience of the activities is undergraduate students, although the activities also may be

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

The adolescence period of life comes along with changes and challenges in terms of physical and cognitive development. In this hectic period, many adolescents may suffer more from various risk factors such as low socioeconomic status, substance abuse, sexual abuse and teenage pregnancy. Findings indicate that such disadvantaged backgrounds of Malaysian adolescent students lead to failure or underachievement in their academic performance. This narrative review scrutinises how some of these students are able to demonstrate academic resilience, which is satisfactory performance in cognitive or academic tasks in spite of their disadvantaged backgrounds. The review stresses the need for developing a caregiving relationship model for at-risk adolescent students in Malaysia. Such a model would allow educators to meet the students' needs for enhancing thinking skills, counteracting risk factors and demonstrating academic resilience. PMID:25663734

The school where I work is part of the "Step by step towards the sustainable development school" project. Project activities are partly directed towards the popularization of science. As a physics teacher, I have had the opportunity to engage in designing interactive workshops, aiming to introduce younger students to simple experiments which illustrate different natural phenomena, and also in organization, preparation and implementation of school and city science festival (in 2012 and 2013). Numerous displays, workshops and experiments served to introduce a large number of visitors to different topics in the area of science and technology. One of the subjects of forthcoming science festival, planned for May of 2014, is the climate change. To that effect, eight grade students will hold a demonstration and explanation of the greenhouse effect. Although the terms greenhouse effect and global warming are widely used in media, most of the elementary school students in Serbia have poor understanding of the underlying scientific concepts. The experiment with analysis and discussion will first be implemented in one eight-grade class (14 years of age). After that, a group of students from this class will present their newly-acquired knowledge to their peers and younger students at the science fair. Activity objectives: • Explain how atmosphere affects the surface temperature of Earth • Conduct an experiment to demonstrate the greenhouse effect • Analyze the consequences of climate changes Experiment description: Take two empty, transparent containers and add a layer of garden soil.

Patterns of Clinical Reasoning in Physical Therapist Students.

PubMed

Gilliland, Sarah; Wainwright, Susan Flannery

2017-05-01

Clinical reasoning is a complex, nonlinear problem-solving process that is influenced by models of practice. The development of physical therapists' clinical reasoning abilities is a crucial yet underresearched aspect of entry-level (professional) physical therapist education. The purpose of this qualitative study was to examine the types of clinical reasoning strategies physical therapist students engage in during a patient encounter. A qualitative descriptive case study design involving within and across case analysis was used. Eight second-year, professional physical therapist students from 2 different programs completed an evaluation and initial intervention for a standardized patient followed by a retrospective think-aloud interview to explicate their reasoning processes. Participants' clinical reasoning strategies were examined using a 2-stage qualitative method of thematic analysis. Participants demonstrated consistent signs of development of physical therapy-specific reasoning processes, yet varied in their approach to the case and use of reflection. Participants who gave greater attention to patient education and empowerment also demonstrated greater use of reflection-in-action during the patient encounter. One negative case illustrates the variability in the rate at which students may develop these abilities. Participants demonstrated development toward physical therapist--specific clinical reasoning, yet demonstrated qualitatively different approaches to the patient encounter. Multiple factors, including the use of reflection-in-action, may enable students to develop greater flexibility in their reasoning processes. © 2017 American Physical Therapy Association

How do video-based demonstration assessment tasks affect problem-solving process, test anxiety, chemistry anxiety and achievement in general chemistry students?

NASA Astrophysics Data System (ADS)

Terrell, Rosalind Stephanie

2001-12-01

Because paper-and-pencil testing provides limited knowledge about what students know about chemical phenomena, we have developed video-based demonstrations to broaden measurement of student learning. For example, students might be shown a video demonstrating equilibrium shifts. Two methods for viewing equilibrium shifts are changing the concentration of the reactants and changing the temperature of the system. The students are required to combine the data collected from the video and their knowledge of chemistry to determine which way the equilibrium shifts. Video-based demonstrations are important techniques for measuring student learning because they require students to apply conceptual knowledge learned in class to a specific chemical problem. This study explores how video-based demonstration assessment tasks affect problem-solving processes, test anxiety, chemistry anxiety and achievement in general chemistry students. Several instruments were used to determine students' knowledge about chemistry, students' test and chemistry anxiety before and after treatment. Think-aloud interviews were conducted to determine students' problem-solving processes after treatment. The treatment group was compared to a control group and a group watching video demonstrations. After treatment students' anxiety increased and achievement decreased. There were also no significant differences found in students' problem-solving processes following treatment. These negative findings may be attributed to several factors that will be explored in this study.

Assessing engineering students' demonstration of workplace competencies in experiential learning environments through internships and cooperative work experiences

NASA Astrophysics Data System (ADS)

Laingen, Mark A.

This study investigates the relationships between supervisor assessments and internship students' self-assessments for 15 workplace competencies, demonstrated in an internship or cooperative work environment. The 15 workplace competencies were developed by Iowa State University in collaboration with over 200 constituents comprised of Iowa State University COE alumni, engineering employers, COE faculty, partnering international faculty, and COE students, to provide clear, independent, and assessable measures for the eleven learning outcomes identified in the ABET Criterion 3 (a-k) outcomes. The study investigated workplace competency assessment data collected over ten years, commencing with the fall 2001 internship assessment term and concluding with the fall 2011 assessment term. The study used three separate methodologies to analyze workplace competency assessments in the COE. Part 1 analyzed data across the fifteen workplace competencies, and across ten programs in the College of Engineering, that have been involved with the workplace competency assessment of internship and cooperative students from the beginning of data collection in 2001. Supervisor assessment ratings were compared to internship student self-assessment ratings across the ten-year span from 2001-11using the non-parametric equivalent of the paired t-test; the Wilcoxon singed rank test for paired data. Part 2 of the study investigated the relationship between supervisor and student self-assessment data across assessment terms related to the 2001-05 and 2006-11 ABET accreditation cycles. The third part investigated how data tracking workplace competency strengths and weaknesses and ABET outcomes achievement percentages have changed between the assessment terms across accreditation cycles. Part 3 included an on-line survey sent to program curriculum committee members involved with workplace competency assessment data that investigated how the engineering programs are utilizing this data in support

Graham, Jeremy; Benson, Lauren M; Swanson, Judy; Potyk, Darryl; Daratha, Kenn; Roberts, Ken

2016-12-01

The primary focus of the study was to determine whether coursework in the medical humanities would ameliorate students' loss of and failure to develop empathy, a problem known to be common during medical education. Students were offered an elective course in the Medical Humanities for academic credit. The Jefferson Scale of Empathy Student Version (JSE-S) was administered at the beginning and end of an academic year in which humanities courses were offered. Changes in JSE-S scores among students who studied Medical Humanities were compared with changes in student who did not take any humanities coursework. Medical humanities coursework correlated with superior empathy outcomes among the medical students. Of students not enrolled in humanities courses, 71% declined or failed to increase in JSE-S score over the academic year. Of those who took humanities coursework, 46% declined or failed to increase in JSE-S scores. The difference was statistically significant (P = .03). The medical humanities curriculum correlated with favorable empathy outcomes as measured by the JSE-S. Elective medical humanities coursework correlated with improved empathy score outcomes in a group of US medical students. This may reflect a direct effect of the humanities coursework. Alternately, students' elective choice to take medical humanities coursework may be a marker for students with a propensity to favorable empathy outcomes. Copyright © 2016 Elsevier Inc.

Graduate healthcare students experience significant stressors during professional training. Mindfulness-Based Stress Reduction (MBSR) is a behavioural intervention designed to teach self-regulatory skills for stress reduction and emotion management. This study examines the impact of MBSR training on students from five healthcare graduate programs in a quasi-experimental trial. A total of 13 students completed the MBSR program and were compared with 15 controls. Both groups answered validated questionnaires measuring anxiety, burnout and empathy at baseline, at conclusion of the course (week 8) and 3 weeks post-course completion (week 11). Significant decrease in anxiety at weeks 8 and 11 compared with baseline (P<0.001 and P<0.01, respectively) was observed using the Burns Anxiety Inventory. Significant increase in empathy at week 8 (P<0.0096) was observed using the Jefferson Scale of Physician Empathy. Week 11 demonstrated a decrease in empathy from baseline (not statistically significant) across all subjects. No significant differences in burnout scores at weeks 8 and 11 were observed between those in the intervention and control groups. These results provide supportive evidence of MBSR as a behavioural intervention to reduce anxiety and increase empathy among graduate healthcare students.

What counts as knowing: Constructing a communicative repertoire for student demonstration of knowledge in science

NASA Astrophysics Data System (ADS)

Crawford, Teresa

2005-02-01

The purpose of this study was twofold. One purpose was to identify the locally negotiated literate practices that defined ways of communicating information and knowledge across the curriculum in a fourth/fifth grade classroom. Through an ethnographic and sociolinguistic set of analyses, this investigation illustrated how the teacher worked to construct a learning environment that valued the use of multiple discourses as a way of communicating competence as a learner. Another purpose was specifically to address the ways that these practices contributed to student demonstration of knowledge in science. This was accomplished by an analysis of one student's presentation of science knowledge after a study of simple machines. A comparative analysis between his use of two discourses, written and oral, showed that the opportunity to choose between multiple discourses led to his success in demonstrating competence in ways that may have otherwise remained questionable.

Medical and psychology students' knowledge and attitudes regarding aging and sexuality.

Snyder, Rachel J; Zweig, Richard A

2010-01-01

The current study surveys medical and doctoral psychology students (N = 100) from an urban northeastern university regarding knowledge and attitudes toward elderly sexuality and aging using the Facts on Aging Quiz, the Aging Sexuality Knowledge and Attitudes Scale, and measures of interest in gerontology, academic/clinical exposure to aging and sexuality, and contact with elders. The current study found that psychology students demonstrated greater aging knowledge than medical students; however, both groups showed gaps in knowledge about sexuality. Married students had greater academic/clinical exposure and greater knowledge about aging but less permissive attitudes toward elderly sexuality. Generally, knowledge about aging was the strongest correlate of knowledge about sexuality. Level of knowledge about sexuality was not associated with attitudes. Attitudes toward sexuality and aging may be more strongly tied to demographic variables reflective of religious beliefs or adherence to sociocultural norms.

The perceptions of inquiry held by greater Houston area science supervisors

NASA Astrophysics Data System (ADS)

Aoki, Jon Michael

The purpose of this study was to describe the perceptions of inquiry held by responding greater Houston area science supervisors. Leading science organizations proposed that students might be better served if students are mentally and physically engaged in the process of finding out about natural phenomena rather than by didactic modes of teaching and learning. During the past fifty years, inquiry-based instruction has become a significant theme of new science programs. Students are more likely to make connections between classroom exercises and their personal lives through the use of inquiry-based instruction. Learning becomes relevant to students. Conversely, traditional science instruction often has little or no connection to students' everyday lives (Papert, 1980). In short, inquiry-based instruction empowers students to become independent thinkers. The utilization of inquiry-based instruction is essential to a successful reform in science education. However, a reform's success is partly determined by the extent to which science supervisors know and understand inquiry and consequently promote its integration in the district's science curricula. Science supervisors have the role of providing curriculum and instructional support to science teachers and for implementing science programs. There is a fundamental need to assess the perceptions of inquiry held by greater Houston area science supervisors. Science supervisor refers to a class of job titles that include department chairperson, science specialist, science consultant, and science coordinator. The target population was greater Houston area science supervisors in Texas. This study suggests that there are three major implications for educational practice. First, there is the implication that responding greater Houston area science supervisors need an inclusive perception of inquiry. Second, responding greater Houston area science supervisors' perception of inquiry may affect the perceptions and understandings

To examine changes in prevalence of obesity and target health behaviors (fruit, vegetable, and beverage consumption; physical activity; screen time; sleep duration) among students from communities that participated in the Massachusetts Childhood Obesity Research Demonstration (MA-CORD) project compared to controls. MA-CORD was implemented in two low-income communities. School-level prevalence of obesity among students in first, fourth, and seventh grades was calculated for the intervention communities and nine matched control communities pre and post intervention. Fourth- and seventh-grade students' self-reported health behaviors were measured in intervention communities at baseline and post intervention. Among seventh-graders (the student group with greatest intervention exposure), a statistically significant decrease in prevalence of obesity from baseline to post intervention in Community 2 (-2.68%, P = 0.049) and a similar but nonsignificant decrease in Community 1 (-2.24%, P = 0.099) was observed. Fourth- and seventh-grade students in both communities were more likely to meet behavioral targets post intervention for sugar-sweetened beverages (both communities: P < 0.0001) and water (Community 1: P < 0.01; Community 2: P = 0.04) and in Community 2 for screen time (P < 0.01). This multisector intervention was associated with a modest reduction in obesity prevalence among seventh-graders in one community compared to controls, along with improvements in behavioral targets. © 2017 The Obesity Society.

Ninth Grade Student Responses to Authentic Science Instruction

NASA Astrophysics Data System (ADS)

Ellison, Michael Steven

This mixed methods case study documents an effort to implement authentic science and engineering instruction in one teacher's ninth grade science classrooms in a science-focused public school. The research framework and methodology is a derivative of work developed and reported by Newmann and others (Newmann & Associates, 1996). Based on a working definition of authenticity, data were collected for eight months on the authenticity in the experienced teacher's pedagogy and in student performance. Authenticity was defined as the degree to which a classroom lesson, an assessment task, or an example of student performance demonstrates construction of knowledge through use of the meaning-making processes of science and engineering, and has some value to students beyond demonstrating success in school (Wehlage et al., 1996). Instruments adapted for this study produced a rich description of the authenticity of the teacher's instruction and student performance. The pedagogical practices of the classroom teacher were measured as moderately authentic on average. However, the authenticity model revealed the teacher's strategy of interspersing relatively low authenticity instructional units focused on building science knowledge with much higher authenticity tasks requiring students to apply these concepts and skills. The authenticity of the construction of knowledge and science meaning-making processes components of authentic pedagogy were found to be greater, than the authenticity of affordances for students to find value in classroom activities beyond demonstrating success in school. Instruction frequently included one aspect of value beyond school, connections to the world outside the classroom, but students were infrequently afforded the opportunity to present their classwork to audiences beyond the teacher. When the science instruction in the case was measured to afford a greater level of authentic intellectual work, a higher level of authentic student performance on

Adding an extra dimension to what students see through the light microscope: a lab exercise demonstrating critical analysis for microscopy students.

PubMed

Garrill, Ashley

2011-01-01

This article describes an undergraduate lab exercise that demonstrates the importance of students thinking critically about what they see through a microscope. The students are given growth data from tip-growing organisms that suggest the cells grow in a pulsatile manner. The students then critique this data in several exercises that incorporate aspects of a problem-based learning approach, envisaging growth not just in two dimensions, but in three dimensions. For some cells, what appears to be pulsatile growth could also be explained by growth at a constant rate up and down in the z-axis. Depending on the diffraction pattern generated by the tip of the cell, this movement in the z-axis could go undetected. This raises the possibility that pulsatile growth seen in some species may be an artifact generated by the limitations of the light microscope. Students were subsequently asked to rate their awareness of the need to think critically about what they see through a microscope, using a scale of 1 (unaware) to 5 (very much aware). Prior to doing the lab exercise, the mean rating was 2.7; this increased to 4.4 after the lab. The students also indicated a likelihood of being more critical in their thinking in other aspects of their biology curriculum.

Visualizing Sound: Demonstrations to Teach Acoustic Concepts

NASA Astrophysics Data System (ADS)

Rennoll, Valerie

Interference, a phenomenon in which two sound waves superpose to form a resultant wave of greater or lower amplitude, is a key concept when learning about the physics of sound waves. Typical interference demonstrations involve students listening for changes in sound level as they move throughout a room. Here, new tools are developed to teach this concept that provide a visual component, allowing individuals to see changes in sound level on a light display. This is accomplished using a microcontroller that analyzes sound levels collected by a microphone and displays the sound level in real-time on an LED strip. The light display is placed on a sliding rail between two speakers to show the interference occurring between two sound waves. When a long-exposure photograph is taken of the light display being slid from one end of the rail to the other, a wave of the interference pattern can be captured. By providing a visual component, these tools will help students and the general public to better understand interference, a key concept in acoustics.

Chan, V; Pisegna, J M; Rosian, R L; DiCarlo, S E

1996-12-01

Employment opportunities in the future will require higher skills and an understanding of mathematics and science. As a result of the growing number of careers that require solid science and mathematics training, the methods of science education are undergoing major reform. To adequately equip students for technologically advanced positions, new teaching methods must be developed that prepare tomorrow's workforce for the challenges of the 21st century. One such method is the use of models. By actively building and manipulating concrete models that represent scientific concepts, students are involved in the most basic level of Piaget's learning scheme: the sensorimotor stage. Models are useful in reaching all students at the foundational levels of learning, and further learning experiences are rapidly moved through higher learning levels. This success ensures greater comprehension and understanding compared with the traditional methods of rote memorization. We developed an exercise for the construction of an inexpensive, easy-to-build model demonstrating neural pathways and reflex arcs. Our exercise also includes many supplemental teaching tools. The exercise is designed to fulfill the need of sound physiological teaching materials for high school students.

It is time for action by leaders across higher education to strengthen quality improvement (QI) in college health, in pursuit of better care, better health, and increased value - goals closely linked to students' learning and success. The size and importance of the college student population; the connections between wellbeing, and therefore QI, and student success; the need for improved standards and greater accountability; and the positive contributions of QI to employee satisfaction and professionalism all warrant a widespread commitment to building greater capacity and capability for QI in college health. This report aims to inspire, motivate, and challenge college health professionals and their colleagues, campus leaders, and national entities to take both immediate and sustainable steps to bring QI to the forefront of college health practice - and, by doing so, to elevate care, health, and value of college health as a key pathway to advancing student success.

What early experiences attract students to pursue an education and career in science, technology, engineering, and mathematics (STEM)? Does hands-on research influence them to persevere and complete a major course of academic study in STEM? We evaluated survey responses from 149 high school and undergraduate students who gained hands-on research experience in the 2007–2013 Aspiring Scientists Summer Internship Programs (ASSIP) at George Mason University. Participants demonstrated their strong interest in STEM by volunteering to participate in ASSIP and completing 300 h of summer research. The survey queried extracurricular experiences, classroom factors, and hands-on projects that first cultivated students’ interest in the STEM fields, and separately evaluated experiences that sustained their interest in pursuing a STEM degree. The majority of students (65.5%, p < 0.0001) reported extracurricular encounters, such as the influence of a relative or family member and childhood experiences, as the most significant factors that initially ignited their interest in STEM, while hands-on lab work was stated as sustaining their interest in STEM (92.6%). Based on these findings collected from a cohort of students who demonstrated a strong talent and interest in STEM, community-based programs that create awareness about STEM for both children and their family members may be key components for igniting long-term academic interest in STEM.

Science, technology, engineering, and mathematics (STEM) graduate students are often encouraged to maximize their engagement with supervised research and minimize teaching obligations. However, the process of teaching students engaged in inquiry provides practice in the application of important research skills. Using a performance rubric, we compared the quality of methodological skills demonstrated in written research proposals for two groups of early career graduate students (those with both teaching and research responsibilities and those with only research responsibilities) at the beginning and end of an academic year. After statistically controlling for preexisting differences between groups, students who both taught and conducted research demonstrate significantly greater improvement in their abilities to generate testable hypotheses and design valid experiments. These results indicate that teaching experience can contribute substantially to the improvement of essential research skills.

The correct and appropriate performance of nursing skills by students can ensure patient safety and care quality. However, developing appropriate teaching and learning strategies to enhance nursing students' nursing skills and knowledge are challenging tasks for nursing faculty members. Nowadays, smartphones are popular mobile devices that are used on campuses by students and could be considered a potential tool to deliver learning materials to nursing students. This study aimed to examine the effects of a skill demonstration video delivered by smartphone on facilitating nursing students' nursing skill competency and confidence. A randomized controlled trial study design was used. A convenience sample of nursing students at a university was recruited. After receiving a regular nursing skills lab demonstration, pre-test data were collected from nursing students in an intervention group (n = 44) and a comparison group (n = 43). Then, students in the intervention group downloaded the skill demonstration video onto their smartphones, while the comparison group did not. Post-test data were collected at 2 weeks after the intervention. There were significant differences in students' urinary catheterization knowledge (F = 4.219, p = 0.04) and skills (F = 6.739, p = 0.013), but there was no difference in students' confidence level (F = 2.201, p = 0.142) between the two groups after the intervention. Furthermore, the average score of the satisfaction level regarding the intervention was 4.46 (SD = 0.43) on a scale of 1-5. This study found that delivering learning materials through smartphones to nursing students is suitable. Although there was no significant difference in students' self-confidence level, students' knowledge and skills were improved by the intervention. Smartphones can serve as a supplemental tool for learning nursing skills. Copyright © 2018 Elsevier Ltd. All rights reserved.

Encouraging students at all grade levels to consider pursuing a career in Science, Technology, Engineering, and Mathematics (STEM) fields i s a national focus. In 2005, the Naval Surface Warfare Center, Dahlgren Division (NSWCDD), a Department of Defense laboratory located in Da hlgren, Virginia, began work on the Virginia Demonstration Project (VDP) with the goal of increasing more student interest in STEM educatio n and pursuing STEM careers. This goal continues as the program enters its sixth year. This project has been successful through the partici pation of NSWCDD's scientists and engineers who are trained as mentor s to work in local middle school classrooms throughout the school year, As an extension of the in-class activities, several STEM summer aca demies have been conducted at NSWCDD, These academies are supported by the Navy through the VDP and the STEM Learning Module Project. These projects are part of more extensive outreach efforts offered by the National Defense Education Program (NDEP), sponsored by the Director, Defense Research and Engineering. The focus of this paper is on the types of activities conducted at the summer academy, an overview of the academy planning process, and recommendations to help support a nati onal plan of integrating modeling and simulation-based engineering and science into all grade levels. based upon the lessons learned

The Effect of Tutoring With Nonstandard Equations for Students With Mathematics Difficulty.

PubMed

Powell, Sarah R; Driver, Melissa K; Julian, Tyler E

2015-01-01

Students often misinterpret the equal sign (=) as operational instead of relational. Research indicates misinterpretation of the equal sign occurs because students receive relatively little exposure to equations that promote relational understanding of the equal sign. No study, however, has examined effects of nonstandard equations on the equation solving and equal-sign understanding of students with mathematics difficulty (MD). In the present study, second-grade students with MD (n = 51) were randomly assigned to standard equations tutoring, combined tutoring (standard and nonstandard equations), and no-tutoring control. Combined tutoring students demonstrated greater gains on equation-solving assessments and equal-sign tasks compared to the other two conditions. Standard tutoring students demonstrated improved skill on equation solving over control students, but combined tutoring students' performance gains were significantly larger. Results indicate that exposure to and practice with nonstandard equations positively influence student understanding of the equal sign. © Hammill Institute on Disabilities 2013.

We evaluated survey responses from 149 high school and undergraduate students who gained hands-on research experience in the 2007-2013 Aspiring Scientists Summer Internship Programs (ASSIP) at George Mason University. Participants demonstrated their strong interest in STEM by volunteering to participate in ASSIP and completing 300 h of summer research. The survey queried extracurricular experiences, classroom factors, and hands-on projects that first cultivated students' interest in the STEM fields, and separately evaluated experiences that sustained their interest in pursuing a STEM degree. The majority of students (65.5%, p < 0.0001) reported extracurricular encounters, such as the influence of a relative or family member and childhood experiences, as the most significant factors that initially ignited their interest in STEM, while hands-on lab work was stated as sustaining their interest in STEM (92.6%). Based on these findings collected from a cohort of students who demonstrated a strong talent and interest in STEM, community-based programs that create awareness about STEM for both children and their family members may be key components for igniting long-term academic interest in STEM. © 2014 A.

Non-physics peer demonstrators in undergraduate laboratories: a study of students’ perceptions

NASA Astrophysics Data System (ADS)

Braun, Michael; Kirkup, Les

2016-01-01

Laboratory demonstrators play a crucial role in facilitating students’ learning in physics subjects. Inspired by the success of peer-led activities, we introduced peer demonstrators to support student learning in first-year physics subjects that enrol students not intending to major in physics. Surveys were administered to 1700 students over 4 years in four subjects to examine student perceptions of how demonstrators assisted them in the laboratory. Scores awarded to peer demonstrators by students were no lower than those awarded to demonstrators traditionally employed in the first year physics laboratory. These latter demonstrators were drawn mainly from the ranks of physics research students. The findings validate the recruitment of peer demonstrators and will be used to inform the recruitment and support programmes for laboratory demonstrators.

Using a physics experiment in a lecture setting to engage biology students with the concepts of Poiseuille's law.

PubMed

Breckler, Jennifer L; Christensen, Tina; Sun, Wendy

2013-06-01

Biology students enrolled in a typical undergraduate physiology course encounter Poiseuille's law, a physics equation that describes the properties governing the flow of blood through the circulation. According to the equation, a small change in vessel radius has an exponential effect on resistance, resulting in a larger than expected change in blood flow. To help engage students in this important concept, we performed a physics experiment as a lecture demonstration to mimic the original research by the 19th-century French scientist. We tested its impact as a research project and found that students who viewed the demonstration reacted very positively and showed an immediate increase in test performance, while the control group was able to independently "catch up" at the fourth week posttest. We further examined whether students' math skills mapped to learning gains. The students with lower math scores who viewed the demonstration had slightly more improvement in test performance than those students who did not view the demonstration. Our data suggest that watching a lecture demonstration may be of even greater benefit to biology students with lower math achievement.

Rose, Barbara L; Mansour, Mona; Kohake, Kelli

2005-12-01

The Cincinnati School Health Demonstration Project was a 3-year collaboration that evaluated school-linked health services in 6 urban elementary (kindergarten to eighth grade) schools. Partners from the Cincinnati Health Department, Cincinnati Public Schools, Cincinnati Children's Hospital Medical Center, and The Health Foundation of Greater Cincinnati wanted to determine if levels of school-linked care made a difference in student quality of life, school connectedness, attendance, emergency department use, and volume of referrals to health care specialists. School nurses, principals and school staff, parents and students, upper-level managers, and health service researchers worked together over a 2.5-year period to learn about and use new technology to collect information on student health, well-being, and outcome measures. Varying levels of school health care intervention models were instituted and evaluated. A standard model of care was compared with 2 models of enhanced care and service. The information collected from students, parents, nurses, and the school system provided a rich database on the health of urban children. School facilities, staffing, and computer technology, relationship building among stakeholders, extensive communication, and high student mobility were factors that influenced success and findings of the project. Funding for district-wide computerization and addition of school health staff was not secured by the end of the demonstration project; however, relationships among the partners endured and paved the way for future collaborations designed to better serve urban school children in Cincinnati.

2015-01-01

BACKGROUND We examined whether fatigue was associated with greater symptomatic burden and functional impairment in college students with depressive symptoms. METHODS Using data from the self-report Beck Depression Inventory (BDI), we stratified a group of 287 students endorsing significant symptoms of depression (BDI score ≥13) into 3 levels: no fatigue, mild fatigue, or moderate/severe fatigue. We then compared the 3 levels of fatigue across a battery of psychiatric and functional outcome measures. RESULTS Approximately 87% of students endorsed at least mild fatigue. Students with moderate/severe fatigue had significantly greater depressive symptom severity compared with those with mild or no fatigue and scored higher on a suicide risk measure than those with mild fatigue. Students with severe fatigue evidenced greater frequency and intensity of anxiety than those with mild or no fatigue. Reported cognitive and functional impairment increased significantly as fatigue worsened. CONCLUSIONS Depressed college students with symptoms of fatigue demonstrated functional impairment and symptomatic burden that worsened with increasing levels of fatigue. Assessing and treating symptoms of fatigue appears warranted within this population. PMID:25954936

Quiroz, Yakeel T.; Hasselmo, Michael E.; Stern, Chantal E.

2009-01-01

Most functional magnetic resonance imaging (fMRI) studies examining working memory (WM) load have focused on the prefrontal cortex (PFC) and have demonstrated increased prefrontal activity with increased load. Here we examined WM load effects in the medial temporal lobe (MTL) using an fMRI Sternberg task with novel complex visual scenes. Trials consisted of 3 sequential events: 1) sample presentation (encoding), 2) delay period (maintenance), and 3) probe period (retrieval). During sample encoding, subjects saw either 2 or 4 pictures consecutively. During retrieval, subjects indicated whether the probe picture matched one of the sample pictures. Results revealed that activity in the left anterior hippocampal formation, bilateral retrosplenial area, and left amygdala was greater at retrieval for trials with larger memory load, whereas activity in the PFC was greater at encoding for trials with larger memory load. There was no load effect during the delay. When encoding, maintenance, and retrieval periods were compared with fixation, activity was present in the hippocampal body/tail and fusiform gyrus bilaterally during encoding and retrieval, but not maintenance. Bilateral dorsolateral prefrontal activity was present during maintenance, but not during encoding or retrieval. The results support models of WM predicting that activity in the MTL should be modulated by WM load. PMID:19224975

Relationship quality and student engagement

NASA Astrophysics Data System (ADS)

Culver, Jennifer

The purpose of this study was to examine the qualities of support, relatedness, and negative interaction within parent-child and teacher-student relationships and their association with cognitive, psychological, and behavioral engagement. Additionally, this study explored the contributions of cognitive and psychological engagement on behavioral engagement. The role of gender, grade, and ethnicity on relationship quality and engagement was also considered. Participants (n=311) were students in grades three through five from a suburban school district in southeastern Michigan. Perceptions of teacher-student relationship quality varied by grade level. In general, younger students reported greater teacher support and relatedness in comparison to older students. Conversely, older students perceived greater conflict within the teacher-student relationship. Student engagement also varied by grade level, with younger students reporting greater engagement than older students. Ethnicity also contributed to variance in student engagement, with African American students reporting significantly more engagement than Caucasian or Multiracial students. Teacher-student relationship quality was a significant predictor of student engagement, even after controlling for student characteristics and parent-child relationship variables. Results of path analysis revealed that cognitive and psychological engagement contributed significantly to behavioral engagement.

Simple Summary We surveyed university students in 11 Eurasian countries for their attitudes to animals, using an internet-based questionnaire to which 1,902 female and 1,530 male student responded from 102 universities. Across countries female students had greater concern for animal welfare and rights than males, but especially so in more gender empowered countries. One contributing factor appeared to be the greater association of females than males with pets, and a possible outcome was greater female avoidance of meat consumption, especially red meat. Abstract Previous research has demonstrated that in households where the male partner is more dominant, there is convergence in male and female attitudes towards animals, whereas if the female partner is empowered they exhibit greater empathy towards animals than the male partner. We tested this theory of ‘female empowered empathy’ internationally in a survey of female and male students' attitudes towards use of animals, conducted in 11 Eurasian countries: China, Czech Republic, Great Britain, Iran, Ireland, South Korea, Macedonia, Norway, Serbia, Spain and Sweden. Gender empowerment was estimated for each country using the Gender Empowerment Measure designed by the United Nations. The survey was administered via the internet in universities within countries, and 1,902 female and 1,530 male student responses from 102 universities were received. Respondents rated the acceptability of 43 major concerns about human use of animals, and the importance of 13 world social issues, including animal protection, environmental protection and sustainable development. Females had greater concern for animal welfare and rights than males. There was a positive correlation between the Gender Empowerment Measure and the ratio of female to male concern for animal welfare and rights, but not for other world issues. Thus in countries where females were more empowered, principally Sweden, Norway and Great Britain, females had much

2006-12-01

Project LITE (Light Inquiry Through Experiments) is a materials, software, and curriculum development project. It focuses on light, optics, color and visual perception. According to two recent surveys of college astronomy faculty members, these are among the topics most often included in the large introductory astronomy courses. The project has aimed largely at the design and implementation of hands-on experiences for students. However, it has also included the development of lecture demonstrations that employ novel light sources and materials. In this presentation, we will show some of our new lecture demonstrations concerning geometrical and physical optics, fluorescence, phosphorescence and polarization. We have developed over 200 Flash and Java applets that can be used either by teachers in lecture settings or by students at home. They are all posted on the web at http://lite.bu.edu. For either purpose they can be downloaded directly to the user's computer or run off line. In lecture demonstrations, some of these applets can be used to control the light emitted by video projectors to produce physical effects in materials (e.g. fluorescence). Other applets can be used, for example, to demonstrate that the human percept of color does not have a simple relationship with the physical frequency of the stimulating source of light. Project LITE is supported by Grant #DUE-0125992 from the NSF Division of Undergraduate Education.

One in four psychiatric beds in Australia are located in the private sector, and more than half of Australian psychiatrists undertake private work. However, nearly all medical student teaching in psychiatry takes place in public hospitals. This paper explores the learning opportunities in the private sector. We report the South Australian experience; medical students have been taught in Ramsay Health Care (SA) Mental Health facilities for more than 23 years. Our experience demonstrates that clinical teaching in private hospitals is sustainable and well accepted by students, patients and clinicians.

Science and fun in a Magic Show of Light from optical demonstrations on an overhead projector for elementary school students

NASA Astrophysics Data System (ADS)

Lones, Joe J.; Maltseva, Nadezhda K.; Peterson, Kurt N.

2007-06-01

We seek methods of stimulating young school children to develop an interest in science and engineering through a natural curiosity for the reaction of light. Science learning now begins fully at middle school. Reading skills develop with activity at home and progress through the elementary school curriculum, and in a like manner, a curious interest in science also should begin at that stage of life. Within the ranks of educators, knowledge of optical science needs to be presented to elementary school students in an entertaining manner. One such program used by the authors is Doug Goodman's Optics Demonstrations With the Overhead Projector, co-published by and available from OSA (Optical Society of America) and SPIE-The International Society of Optical Engineering. These demonstrations have found their way into middle and high schools; however, as a special approach, the authors have presented selected Goodman demonstrations as a "Magic Show of Light" to elementary schools. Both students and faculty have found the show most entertaining! If optical knowledge is utilized to stimulate science learning in the coming generation at elementary school level, there's a good chance we can sow some fertile seeds of advancement for all future segments of the workforce. Students can enjoy what they are doing while building a foundation for contributing gainfully to society in any profession. We need to explore expanding exposure of the "Magic Show of Light" to elementary schools.

Denny, Simon; Howie, Hamish; Grant, Sue; Galbreath, Ross; Utter, Jennifer; Fleming, Theresa; Clark, Terryann

2018-01-01

Objective School-based health services (SBHS) have been shown to improve access to mental health services but the evidence of their effectiveness on students' mental health is lacking. Our objective was to examine associations between variation in the provision of SBHS and students' mental health. Methods A cross-sectional analysis of a nationally representative health and well-being survey of 8500 New Zealand high school students conducted in March-November 2012. Students' mental health is related to data on school health services obtained from clinic leaders and clinicians from 90 participating high schools. Results After adjustment for socio-demographic differences in students between schools, increasing levels of services were associated with progressively lower levels of student-reported depressive symptoms (p = 0.002), emotional and behavioural difficulties (p = 0.004) and suicidality (p = 0.008). Services with greater levels of nursing hours (p = 0.02) and those that performed routine, comprehensive psychosocial assessments (p = 0.01) were both associated with lower levels of student-reported depressive symptoms. Greater levels of nursing hours and doctor hours were associated with lower self-reported suicidality among students. Conclusions Although a causal association between school-based health services and students' mental health cannot be demonstrated, these findings support the benefit of such services and the need for a cluster randomized trial.

The first direct dating of Main Central Thrust phyllonite demonstrates exhumation of the Greater Himalayan Crystalline had already taken place

NASA Astrophysics Data System (ADS)

Rajabi, Sareh; Forster, Marnie; Ahmad, Talat; Lister, Gordon

2017-04-01

Here we report the results of step-heating experiments that allow the first direct dating of the timing of movement on the Himalayan Main Central Thrust (MCT). Timing of MCT operation has, until now, been inferred based on specific tectonic models, or with data not directly attributable to MCT movement, e.g., the debatable assertion that leucogranite formation is invariably related to crustal shortening, and therefore that the MCT must already have been in operation. However the tectonic evolution may have been more complex, e.g., at times involving horizontal extension. In any case, many different thrust systems operated during India-Asia convergence, and the MCT is only one of them. It is time to move away from models and to bring geology back into the equation. Here we apply 40Ar/39Ar geochronology to directly date highly strained, phyllonitized, muscovite in the MCT above the Kullu-Rampur tectonic window (NW Indian Himalaya), showing that the timing of the shear movement lasted from 15-9 Ma. We show that these ages have been preserved because the white mica was sufficiently retentive of argon to be able to inhibit its diffusional loss at the temperatures and pressures in question. Arrhenius data from ultra-high-vacuum diffusion experiments show that deformation occurred below the closure temperature of this muscovite, for moderate cooling rates. Furthermore, we demonstrate that microscopic shear bands associated with MCT operation overprinted an earlier decussate mica growth. This decussate growth had taken place prior to ˜ 18 Ma. The decussate microstructure, together with foam textures in the host deformed quartzite, demonstrate that low deviatoric stress conditions applied during a prior period of static annealing under middle- to upper-greenschist facies conditions. In this region, therefore, the Greater Himalayan Crystalline had therefore already been significantly exhumed prior to the onset of MCT operation. The foam textures in quartzite and the

Using a Physics Experiment in a Lecture Setting to Engage Biology Students with the Concepts of Poiseuille's Law

Biology students enrolled in a typical undergraduate physiology course encounter Poiseuille's law, a physics equation that describes the properties governing the flow of blood through the circulation. According to the equation, a small change in vessel radius has an exponential effect on resistance, resulting in a larger than expected change in blood flow. To help engage students in this important concept, we performed a physics experiment as a lecture demonstration to mimic the original research by the 19th-century French scientist. We tested its impact as a research project and found that students who viewed the demonstration reacted very positively and showed an immediate increase in test performance, while the control group was able to independently “catch up” at the fourth week posttest. We further examined whether students’ math skills mapped to learning gains. The students with lower math scores who viewed the demonstration had slightly more improvement in test performance than those students who did not view the demonstration. Our data suggest that watching a lecture demonstration may be of even greater benefit to biology students with lower math achievement. PMID:23737633

Greater fruit selection following an appearance-based compared with a health-based health promotion poster

PubMed Central

2016-01-01

Abstract Background This study investigated the impact of an appearance-based compared with a traditional health-based public health message for healthy eating. Methods A total of 166 British University students (41 males; aged 20.6 ± 1.9 years) were randomized to view either an appearance-based (n = 82) or a health-based (n = 84) fruit promotion poster. Intentions to consume fruit and immediate fruit selection (laboratory observation) were assessed immediately after poster viewing, and subsequent self-report fruit consumption was assessed 3 days later. Results Intentions to consume fruit were not predicted by poster type (largest β = 0.03, P = 0.68) but were associated with fruit-based liking, past consumption, attitudes and social norms (smallest β = 0.16, P = 0.04). Immediate fruit selection was greater following the appearance-based compared with the health-based poster (β = −0.24, P < 0.01), and this effect remained when controlling for participant characteristics (β = −0.21, P < 0.01). Subsequent fruit consumption was greater following the appearance-based compared with the health-based poster (β = −0.22, P = 0.03), but this effect became non-significant on consideration of participant characteristics (β = −0.15, P = 0.13), and was instead associated with fruit-based liking and past consumption (smallest β = 0.24, P = 0.03). Conclusions These findings demonstrate the clear value of an appearance-based compared with a health-based health promotion poster for increasing fruit selection. A distinction between outcome measures and the value of a behavioural measure is also demonstrated. PMID:28158693

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.

Perceived racial discrimination, heavy episodic drinking, and alcohol abstinence among African American and White college students.

PubMed

Wade, Jeannette; Peralta, Robert L

2017-01-01

Previous research has demonstrated that White college students are more likely to drink alcohol at a greater frequency and quantity compared to their African American counterparts. Examining race-related factors that structure alcohol use among college students remains an important area of research. In this study, we specifically examine perceived discrimination and its association with both heavy episodic drinking (HED) and alcohol abstinence among college students. Items that measured perceived racial discrimination in alcohol use contexts and demographic characteristics were used as independent and control variables. African American students were more likely to abstain from alcohol and less likely to engage in HED compared to their White counterparts. Results also suggest that students who believe their drinking will solicit race-based police bias have lower odds of engaging in HED and greater odds of alcohol abstention. We conclude that unsolicited policing, experienced by African Americans generally, and White Americans on campuses, explains effect sizes.

Validity of Medical Student Questionnaire Data in Prediction of Rural Practice Choice and Its Association With Service Orientation.

PubMed

Shannon, C Ken; Jackson, Jodie

2015-01-01

The validity of medical student projection of, and predictors for, rural practice and the association of a measure of service orientation, projected practice accessibility to the indigent, were investigated. West Virginia (WV) medical student online pre- and postrural rotation questionnaire data were collected during the time period 2001-2009. Of the 1,517 respondent students, submissions by 1,271 met the time interval criterion for inclusion in analyses. Subsequent WV licensing data were available for 461 in 2013. These 2 databases were used to assess for validity of projection of rural practice, for predictors of rural practice, and for student projected accessibility of the future practice to indigent patients. There were statistically significant associations between both pre- and postrotation projections of rural practice and subsequent rural practice. The most significant independent predictors of rural practice were student rural background, reported primary care intent, prediction of rural practice and projection of greater accessibility of the future practice to indigent patients. For scoring of practice access, there were trends for higher scoring by rural students and rural practitioners, with greater pre-post increases for those with urban hometowns. This study demonstrates the utility of medical student questionnaires for projections of numbers of future rural physicians. It suggests that students with a rural background, rural practice intent, or greater service orientation are more likely to enter rural practice. It also suggests that students, particularly those with urban hometowns, are influenced by rural rotation experiences in forecasting greater practice accessibility and in entering rural practice. © 2015 National Rural Health Association.

We present a collection of demonstrations using common foods to illustrate factors that influence bubble and crystal nucleation and growth in magmas, and consequences for volcanic processes. Using foods such as soda water, raisins, fudge, popcorn and cake, ensures that the demonstration are safe, cheap and can be repeated by students (with variations) in their own kitchens. From these experiments students learn about the influence of crystals and bubbles on magma rheology and permeability, and how these properties in turn affect lava flow morphologies, crystal fractionation, the formation of breadcrust bombs, and styles of volcanic eruptions.

A randomized controlled pilot trial comparing the impact of access to clinical endocrinology video demonstrations with access to usual revision resources on medical student performance of clinical endocrinology skills

PubMed Central

2013-01-01

Background Demonstrating competence in clinical skills is key to course completion for medical students. Methods of providing clinical instruction that foster immediate learning and potentially serve as longer-term repositories for on-demand revision, such as online videos demonstrating competent performance of clinical skills, are increasingly being used. However, their impact on learning has been little studied. The aim of this study was to determine the value of adjunctive on-demand video-based training for clinical skills acquisition by medical students in endocrinology. Methods Following an endocrinology clinical tutorial program, 2nd year medical students in the pre-assessment revision period were recruited and randomized to either a set of bespoke on-line clinical skills training videos (TV), or to revision as usual (RAU). The skills demonstrated on video were history taking in diabetes mellitus (DMH), examination for diabetes lower limb complications (LLE), and examination for signs of thyroid disease (TE). Students were assessed on these clinical skills in an observed structured clinical examination two weeks after randomization. Assessors were blinded to student randomization status. Results For both diabetes related clinical skills assessment tasks, students in the TV group performed significantly better than those in the RAU group. There were no between group differences in thyroid examination performance. For the LLE, 91.7% (n = 11/12) of students randomized to the video were rated globally as competent at the skill compared with 40% (n = 4/10) of students not randomized to the video (p = 0.024). For the DMH, 83.3% (n = 10/12) of students randomized to the video were rated globally as competent at the skill compared with 20% (n = 2/10) of students not randomized to the video (p = 0.007).

Objective. To assess graduating pharmacy students' attitudes toward debt and determine associations with stress, student loan debt, financial need, current employment, post-graduation plans, and expected length of time to repay loans. Methods. Survey was conducted using an attitudes-toward-debt scale (sub-scales: tolerant attitudes toward debt; contemplation and knowledge about loans; fear of debt), Perceived Stress Scale, and questions concerning current employment, estimated total student loan debt, post-graduation plans, and expected length of time to repay loans. Federal loan data were collected using financial aid records. Independent samples t -test, ANOVA, and Pearson's r correlations were conducted. Results. There were 147 students (96.7%) who participated. The majority were female (59.2%), white (69.4%), and had federal student loans (90.5%). Mean total loan amount was $153,276 (SD $59,810), which included federal students loans accumulated before and during pharmacy school. No significant differences were noted on attitudes toward debt or stress based on whether respondents had federal student loans. Greater "fear of debt" was correlated with increased stress, estimated total student loan debt, total federal loan debt, and pharmacy school loan debt. Greater "contemplation and knowledge about loans" was correlated with lower estimated total student loan debt, total federal loan amount, and pharmacy school loan amount. Students with higher "contemplation and knowledge" scores expected to repay loans within a shorter time frame than students with lower scores. Conclusion. Increased fear of debt was related to greater perceived stress and higher student loan amounts borrowed, while increased contemplation and knowledge about loans was associated with lower amounts borrowed. Educational programming concerning loans, debt, and personal financial management may help reduce stress and amount borrowed.

Magnetic levitation on a type-I superconductor as a practical demonstration experiment for students

We describe and discuss an experimental set-up which allows undergraduate and graduate students to view and study magnetic levitation on a type-I superconductor. The demonstration can be repeated many times using one readily available 25 l liquid helium dewar. We study the equilibrium position of a magnet that levitates over a lead bowl immersed in a liquid hand-held helium cryostat. We combine the measurement of the position of the magnet with simple analytical calculations. This provides a vivid visualization of magnetic levitation from the balance between pure flux expulsion and gravitation. The experiment contrasts and illustrates the case of magnetic levitation with high temperature type-II superconductors using liquid nitrogen, where levitation results from partial flux expulsion and vortex physics.

Misconceptions and stigma associated with autism vary across cultures and may be influenced by various factors. Undergraduates in Japan (N = 212) and the United States (US) (N = 365) completed an online autism training, with pre- and posttest surveys assessing autism-related stigma (i.e., social distance) and knowledge. Aims were to examine differences in autism stigma and knowledge in Japan and the US, while extending prior research demonstrating benefits of an online autism training in the US and Lebanon to Japan. The results revealed that Japanese students indicated greater autism-related stigma than US students, which was not attributable to differences in autism knowledge, prior experience with autism, or college major. In both countries, students majoring in "helping professions" exhibited greater willingness to engage with people with autism. Japanese and US students varied in their misconceptions about autism, with significant differences on about half of the knowledge items. Japanese students showed decreased stigma after completing the autism training, yet continued to exhibit greater social distance towards people with autism relative to US students. Future research should focus on identifying specific cultural factors (e.g., conformity to social norms and homogeneity within communities) that contribute to fear and exclusion of people with autism in different societies.

The purpose of this study was to compare the efficacy of simulation versus lecture-based education among preclinical medical students. Twenty medical students participated in this randomized, controlled crossover study. Students were randomized to four groups. Each group received two simulations and two lectures covering four different topics. Students were administered a pre-test, post-test and delayed post-test. The mean percentage of questions answered correctly on each test was calculated. The mean of each student's change in score across the three tests was used to compare simulation- versus lecture-based education. Students in both the simulation and lecture groups demonstrated improvement between the pre-test and post-test (p < 0.05). Students in the simulation group demonstrated improvement between the immediate post-test and delayed post-test (p < 0.05), while students in the lecture group did not demonstrate improvement (p > 0.05). When comparing interventions, the change in score between the pre-test and post-test was similar among both the groups (p > 0.05). The change in score between the post-test and delayed post-test was greater in the simulation group (p < 0.05). High-fidelity simulation may serve as a viable didactic platform for preclinical medical education. Our study demonstrated equivalent immediate knowledge gain and superior long-term knowledge retention in comparison to lectures.

The pre-clinical curriculum at the University of New Mexico School of Medicine is a hybrid model that includes small group, problem-based learning (PBL) tutorials and didactic lectures. A structured tutorial format was piloted for the human sexuality/reproduction organ system block for the PBL component. The objective of this study was to compare the acceptability of the structured format and its effectiveness with that of a traditional PBL tutorial. Students were surveyed after the renal/endocrinology block of 2004 (traditional tutorial format) and after the human sexuality/reproduction block of 2004 (structured tutorial format) (n = 70). Survey questions covered the quality of learning and of tutorial. Students (n = 132) and tutors (n = 24) who participated in human sexuality/reproduction in 2004 and 2005 were surveyed for attitudes about the structured tutorial overall and specific components. Means of responses were compared using t-tests. Students indicated that the structured tutorial format supported a greater improvement in their basic science and clinical knowledge and their ability to evaluate information (p < 0.05). The majority of students and tutors recommended the structured format for tutorials in other blocks. We demonstrated the acceptability of a structured tutorial format to students and faculty. Faculty members perceived greater depth of learning and participation by the students.

Instructional multimedia: An investigation of student and instructor attitudes and student study behavior

PubMed Central

2011-01-01

Background Educators in allied health and medical education programs utilize instructional multimedia to facilitate psychomotor skill acquisition in students. This study examines the effects of instructional multimedia on student and instructor attitudes and student study behavior. Methods Subjects consisted of 45 student physical therapists from two universities. Two skill sets were taught during the course of the study. Skill set one consisted of knee examination techniques and skill set two consisted of ankle/foot examination techniques. For each skill set, subjects were randomly assigned to either a control group or an experimental group. The control group was taught with live demonstration of the examination skills, while the experimental group was taught using multimedia. A cross-over design was utilized so that subjects in the control group for skill set one served as the experimental group for skill set two, and vice versa. During the last week of the study, students and instructors completed written questionnaires to assess attitude toward teaching methods, and students answered questions regarding study behavior. Results There were no differences between the two instructional groups in attitudes, but students in the experimental group for skill set two reported greater study time alone compared to other groups. Conclusions Multimedia provides an efficient method to teach psychomotor skills to students entering the health professions. Both students and instructors identified advantages and disadvantages for both instructional techniques. Reponses relative to instructional multimedia emphasized efficiency, processing level, autonomy, and detail of instruction compared to live presentation. Students and instructors identified conflicting views of instructional detail and control of the content. PMID:21693058

Emphasizing the process of science using demonstrations in conceptual chemistry

NASA Astrophysics Data System (ADS)

Lutz, Courtney A.

The purpose of this project was to teach students a method for employing the process of science in a conceptual chemistry classroom when observing a demonstration of a discrepant event. Students observed six demonstrations throughout a trimester study of chemistry and responded to each demonstration by asking as many questions as they could think of, choosing one testable question to answer by making as many hypotheses as possible, and choosing one hypothesis to make predictions about observed results of this hypothesis when tested. Students were evaluated on their curiosity, confidence, knowledge of the process of science, and knowledge of the nature of science before and after the six demonstrations. Many students showed improvement in using or mastery of the process of science within the context of conceptual chemistry after six intensive experiences with it. Results of the study also showed students gained confidence in their scientific abilities after completing one trimester of conceptual chemistry. Curiosity and knowledge of the nature of science did not show statistically significant improvement according to the assessment tool. This may have been due to the scope of the demonstration and response activities, which focused on the process of science methodology instead of knowledge of the nature of science or the constraints of the assessment tool.

Construct: Clinical skills are used in the care of patients, including reporting, diagnostic reasoning, and decision-making skills. Written comprehensive new patient admission notes (H&Ps) are a ubiquitous part of student education but are underutilized in the assessment of clinical skills. The interpretive summary, differential diagnosis, explanation of reasoning, and alternatives (IDEA) assessment tool was developed to assess students' clinical skills using written comprehensive new patient admission notes. The validity evidence for assessment of clinical skills using clinical documentation following authentic patient encounters has not been well documented. Diagnostic justification tools and postencounter notes are described in the literature (1,2) but are based on standardized patient encounters. To our knowledge, the IDEA assessment tool is the first published tool that uses medical students' H&Ps to rate students' clinical skills. The IDEA assessment tool is a 15-item instrument that asks evaluators to rate students' reporting, diagnostic reasoning, and decision-making skills based on medical students' new patient admission notes. This study presents validity evidence in support of the IDEA assessment tool using Messick's unified framework, including content (theoretical framework), response process (interrater reliability), internal structure (factor analysis and internal-consistency reliability), and relationship to other variables. Validity evidence is based on results from four studies conducted between 2010 and 2013. First, the factor analysis (2010, n = 216) yielded a three-factor solution, measuring patient story, IDEA, and completeness, with reliabilities of .79, .88, and .79, respectively. Second, an initial interrater reliability study (2010) involving two raters demonstrated fair to moderate consensus (κ = .21-.56, ρ =.42-.79). Third, a second interrater reliability study (2011) with 22 trained raters also demonstrated fair to moderate agreement

Background Sleep disturbance (SD) has complex associations with depression, both preceding and following the onset and recurrence of depression. We hypothesized that students with depressive symptoms with SD would demonstrate a greater burden of comorbid psychiatric symptoms and functional impairment compared to students with depressive symptoms without SD. Methods During a mental health screening, 287 undergraduate students endorsed symptoms of depression (Beck Depression Inventory [BDI] ≥ 13) and filled out the following self-report measures: demographic questionnaire, BDI, Anxiety Symptom Questionnaire—intensity and frequency (ASQ), Beck Hopelessness Scale (BHS), Beck Anxiety Inventory (BAI), Quality of Life Enjoyment and Satisfaction Questionnaire (QLESQ), and the Massachusetts General Hospital Cognitive and Physical Functioning Questionnaire (CPFQ). SD was measured using the BDI sleep item #16 dichotomized (score 0: no SD; or score > 0: some SD). Results Students with depressive symptoms and SD (n = 220), compared to those without SD (n = 67), endorsed significantly more intense and frequent anxiety and poorer cognitive and physical functioning. Students with depressive symptoms with and without SD did not significantly differ in depressive severity, hopelessness, or quality of life. Conclusions College students with depressive symptoms with SD may experience a greater burden of comorbid anxiety symptoms and hyperarousal, and may have impairments in functioning, compared to students with depressive symptoms without SD. These findings require replication. Depression and Anxiety 00:1–8, 2013. PMID:23681944

Student conceptions of the nature of science

NASA Astrophysics Data System (ADS)

Talbot, Amanda L.

Research has shown that students from elementary school to college have major misconceptions about the nature of science. While an appropriate understanding of the nature of science has been an objective of science education for a century, researchers using a variety of instruments, continue to document students' inadequate conceptions of what science is and how it operates as an enterprise. Current research involves methods to improve student understanding of the nature of science. Students often misunderstand the creative, subjective, empirical, and tentative nature of science. They do not realize the relationship between laws and theories, nor do they understand that science does not follow a prescribed method. Many do not appreciate the influence culture, society, and politics; nor do they have an accurate understanding of the types of questions addressed by science. This study looks at student understanding of key nature of science (NOS) concepts in order to examine the impact of implementing activities intended to help students better understand the process of science and to see if discussion of key NOS concepts following those activities will result in greater gains in NOS understanding. One class received an "activities only" treatment, while the other participated in the same activities followed by explicit discussion of key NOS themes relating to the activity. The interventions were implemented for one school year in two high school anatomy and physiology courses composed of juniors and seniors. Student views of the nature of science were measured using the Views of the Nature of Science-Form C (VNOS-C). Students in both classes demonstrated significant gains in NOS understanding. However, contrary to current research, the addition of explicit discussion did not result in significantly greater gains in NOS understanding. This suggests that perhaps students in higher-level science classes can draw the correlations between NOS related activities and

Persistence factors among engineering students at the Polytechnic University of Puerto Rico: Student perceptions and curricular implications

NASA Astrophysics Data System (ADS)

Gonzalez Juarbe, Juan M.

Various persistence studies demonstrate that there is a direct correlation between college or university academic program completion and the amount of students' involvement in the college or university on a social, academic, and institutional level. These studies suggest that, over the course of time, the greater the level of involvement the greater the probability of increased persistence towards program completion. Student persistence among Hispanic engineering students was researched at the Polytechnic University of Puerto Rico during the period of January 2002 to April 2003. Persistence factors lead students to either one of the following behaviors: (1) to re-enroll, (2) to switch to another educational program, or (3) to depart from the institution. Increased student persistence is the result of recurring decisions to re-enroll each trimester. Decreased student persistence is the outcome associated with a decision to either depart or switch to another educational vocation. Early departure at the institution is linked to perceptions formed day-to-day as the student experiences the educational environment. These perceptions inspire behavioral outcomes to either persist or depart the education process. Desirable behavioral outcomes are closely related with educational commitments leading to increased persistence. Likewise, undesirable behavioral outcomes are those resulting in decreased persistence. Satisfactory student experiences in successfully achieving social, academic, and institutional responsibilities set the course towards increased persistence. In the research undertaken, student and faculty educational experiences were analyzed and documented. This was accomplished by the use of a combined quantitative and qualitative research methodology. The volunteer participants in this study included: six full time professors, eight part time professors, eighty-one students at a job fair, and seven individual student participants.

The purpose of this study is to investigate whether differences identified between first-year law and medical students in North America in the 1950s apply in the UK in the 1990s. First-year law and medical students are compared in terms of commitment to career, alternative career choices and length of time the student has wished to study for his/her chosen profession. Questionnaires were administered to first-year law students at the University of East Anglia and Essex University and to first-year medical students at Liverpool University Medical School and St George's Hospital Medical School. A total of 162 questionnaires were completed by law students and 195 questionnaires from medical students. The questionnaire responses provided by law and medical students were analysed using a series of two-sample comparisons. Differences between the two groups were examined using t and chi-squared tests. In each of the seven questions answered by students, the differences between the law and medical students were found to be significant. This suggests a difference in career aspirations and perceptions between the two groups. The study shows a greater commitment of medical students than law students to their chosen career. This is demonstrated by medical students' greater desire to pursue their career, their greater satisfaction with their choice of career and finding that more medical students would persist with reapplying for medicine than law students would in reapplying for law. It is also shown that medical students are twice as likely as law students to have a family member within the profession.

Education Not Discrimination (END) is the component of the Time to Change programme intended to reduce mental health stigma among professionals and professional trainees. To investigate the impact of the END anti-stigma programme on medical students immediately and after 6 months with regard to knowledge, attitudes, behaviour and empathy. A total of 1452 medical students participated in the study (intervention group n = 1066, control group n = 386). Participants completed questionnaires at baseline, and at immediate and 6-month follow-up. Groups were compared for changes in stigma outcomes. All measures improved in both groups, particularly among students with less knowledge and more stigmatising attitudes and intended behaviour at baseline. At immediate follow-up the intervention group demonstrated significantly greater improvements in stigma-related knowledge and reductions in stigma-related attitudes and intended behaviour, relative to the control group. At 6 months' follow-up, however, only one attitude item remained significantly better. Although the intervention produced short-term advantage there was little evidence for its persistent effect, suggesting a need for greater integration of ongoing measures to reduce stigma into the medical curriculum.

Preferred Methods of Learning for Nursing Students in an On-Line Degree Program.

PubMed

Hampton, Debra; Pearce, Patricia F; Moser, Debra K

Investigators have demonstrated that on-line courses result in effective learning outcomes, but limited information has been published related to preferred teaching strategies. Delivery of on-line courses requires various teaching methods to facilitate interaction between students, content, and technology. The purposes of this study were to understand student teaching/learning preferences in on-line courses to include (a) differences in preferred teaching/learning methods for on-line nursing students across generations and (b) which teaching strategies students found to be most engaging and effective. Participants were recruited from 2 accredited, private school nursing programs (N=944) that admit students from across the United States and deliver courses on-line. Participants provided implied consent, and 217 (23%) students completed the on-line survey. Thirty-two percent of the students were from the Baby Boomer generation (1946-1964), 48% from Generation X (1965-1980), and 20% from the Millennial Generation (born after 1980). The preferred teaching/learning methods for students were videos or narrated PowerPoint presentations, followed by synchronous Adobe Connect educations sessions, assigned journal article reading, and e-mail dialog with the instructor. The top 2 methods identified by participants as the most energizing/engaging and most effective for learning were videos or narrated PowerPoint presentations and case studies. The teaching/learning method least preferred by participants and that was the least energizing/engaging was group collaborative projects with other students; the method that was the least effective for learning was wikis. Baby Boomers and Generation X participants had a significantly greater preference for discussion board (P<.0167) than millennial students. Millennial students also had a greater preference for simulation than did Baby Boomer and Generation X students and rated on-line games as significantly more energizing/engaging and

Effective admissions practices to achieve greater student diversity in dental schools.

PubMed

Price, Shelia S; Grant-Mills, Donna

2010-10-01

In this chapter we describe the institutional and policy-level strategies that dental schools in the Pipeline, Profession, and Practice: Community-Based Dental Education program used to modify their admissions practices to increase the diversity of their student bodies. Schools developed and used clear statements recognizing the value of diversity. They incorporated recent U.S. Supreme Court rulings regarding educational diversity into their revised admissions practices; these rulings cited diversity as both a "compelling interest" and its use in only "narrowly tailored" circumstances. We make a case for admissions decisions based on a comprehensive evaluation that balances the quantitative and qualitative qualities of a candidate. It refutes the practice of overreliance on standardized tests by detailing the whole-file review process to measure merit and professional promise. Also described is a range of noncognitive variables (e.g., leadership, ability to sustain academic achievement with competing priorities, volunteerism, communication, social background, and disadvantaged status) that schools can take into consideration in admissions decisions. Admissions committees can tie this comprehensive review of candidates into the case for promoting cross-cultural understanding and enhanced competence to provide care to patients from diverse backgrounds. In addition, the chapter reviews the challenges schools face in developing admissions policies and procedures that reflect the university's mission for diversity. It addresses the importance of a diverse composition of the admissions committee. It also describes how tailored workshops and technical assistance for admissions committees can help schools improve their student diversity and how admissions committees can engage in a process of periodic review of their diversity objectives in relationship to the school's mission.

Borderless STEM education: A study of both American students and foreign students

NASA Astrophysics Data System (ADS)

Komura, Kiriko

This study explores the current status of borderless education in STEM through surveys of two populations of STEM students: American students who studied abroad and foreign students who were studying in the U.S. It was undertaken in response to the U.S. government's desires to strengthen STEM education and to develop American students' global competencies. The purpose was to understand how international experiences can be enhanced in order to increase American STEM students' interest in study abroad programs and in earning advanced STEM degrees and to understand how to attract more foreign STEM students to study in the United States. Issues of particular focus were: the impacts of gender, race/ethnicity, and nationality on STEM students' motivation to participate in, and responses to study abroad programs, and the value of Information and Communication Technologies (ICTs) in borderless STEM education. Several different forms of multivariate analyses were performed on data from surveys at seven public and private colleges and universities in the Southern California area. The results indicated that among American students, greater value was placed on social and cultural experiences gained through studying abroad. In contrast, among foreign students greater value was placed on enhancement of their academic and professional development opportunities. American students whose study abroad included research experiences had a greater interest in international research and teaching in the future. Foreign graduate students majoring in computer science, engineering and biology are the most likely to seek opportunities to study and work in the US. Finally, ICTs were valued by American students as platforms for social interactions and by foreign students for facilitating professional networks. The analyses lead to several recommendations, including: STEM faculty should be made aware of the critical importance of their advising and mentoring in motivating students to choose to

Large data sets on human genetic variation have been collected recently, but their usefulness for learning about history and natural selection has been limited by biases in the ways polymorphisms were chosen. We report large subsets of SNPs from the International HapMap Project that allow us to overcome these biases and to provide accurate measurement of a quantity of crucial importance for understanding genetic variation: the allele frequency spectrum. Our analysis shows that East Asian and northern European ancestors shared the same population bottleneck expanding out of Africa but that both also experienced more recent genetic drift, which was greater in East Asians.

Previous research has demonstrated that in households where the male partner is more dominant, there is convergence in male and female attitudes towards animals, whereas if the female partner is empowered they exhibit greater empathy towards animals than the male partner. We tested this theory of 'female empowered empathy' internationally in a survey of female and male students' attitudes towards use of animals, conducted in 11 Eurasian countries: China, Czech Republic, Great Britain, Iran, Ireland, South Korea, Macedonia, Norway, Serbia, Spain and Sweden. Gender empowerment was estimated for each country using the Gender Empowerment Measure designed by the United Nations. The survey was administered via the internet in universities within countries, and 1,902 female and 1,530 male student responses from 102 universities were received. Respondents rated the acceptability of 43 major concerns about human use of animals, and the importance of 13 world social issues, including animal protection, environmental protection and sustainable development. Females had greater concern for animal welfare and rights than males. There was a positive correlation between the Gender Empowerment Measure and the ratio of female to male concern for animal welfare and rights, but not for other world issues. Thus in countries where females were more empowered, principally Sweden, Norway and Great Britain, females had much greater concern than males for animal issues, whereas in other countries the responses of males and females were more similar. Across countries female students were more likely to avoid meat and less likely to avoid eggs, milk and seafood than male students, and were more likely to have kept pets than males. Females rated cats as more sentient than males did. The results demonstrate that females have greater concern for animal welfare and rights than males, and that this is more likely to be expressed in countries where females are relatively empowered, suggesting that

Sleep patterns and impulse control among Japanese junior high school students.

Adolescents with decreased impulse control exhibit behavioral problems. Lifestyles are related to impulse control. However, the relations of sleep patterns and impulse control among adolescents are unknown. Thus we examined how sleep patterns were associated with impulse control among Japanese junior high school students. Surveys were completed by a nationwide sample of 1934 students. A significant association between decreased impulse control and bedtimes after midnight was revealed. Specific lifestyle factors related to bedtimes after midnight were older age, greater numbers of hours spent watching television, lack of participation in an extracurricular activity, greater use of convenience stores, and increased attendance at cram schools. This study revealed that going to sleep after midnight was significantly related to decreased impulse control among adolescents. Data about specific lifestyle factors related to going to sleep after midnight should be useful in preventing those behaviors demonstrated by school children that derive from decreased impulse control.

Increasing the Use of Student-Centered Pedagogies from Moderate to High Improves Student Learning and Attitudes about Biology

Connell, Georgianne L.; Donovan, Deborah A.; Chambers, Timothy G.

2016-01-01

Student-centered strategies are being incorporated into undergraduate classrooms in response to a call for reform. We tested whether teaching in an extensively student-centered manner (many active-learning pedagogies, consistent formative assessment, cooperative groups; the Extensive section) was more effective than teaching in a moderately student-centered manner (fewer active-learning pedagogies, less formative assessment, without groups; the Moderate section) in a large-enrollment course. One instructor taught both sections of Biology 101 during the same quarter, covering the same material. Students in the Extensive section had significantly higher mean scores on course exams. They also scored significantly higher on a content postassessment when accounting for preassessment score and student demographics. Item response theory analysis supported these results. Students in the Extensive section had greater changes in postinstruction abilities compared with students in the Moderate section. Finally, students in the Extensive section exhibited a statistically greater expert shift in their views about biology and learning biology. We suggest our results are explained by the greater number of active-learning pedagogies experienced by students in cooperative groups, the consistent use of formative assessment, and the frequent use of explicit metacognition in the Extensive section.

Teaching and learning activities in the dental clinic or hospital are a challenging area for students as well as teachers. With various teaching methodologies being used in dental schools around the world, gaining greater understanding of students' attitudes toward these methodologies would be useful for dental educators. The objective of this study was to explore the preferences of dental students in India about various aspects of lecture courses. A structured survey consisting of ten closed-ended questions was developed, and 2,680 undergraduate students from forty-three dental schools in India were approached via e-mail with a follow-up postal mailing. Of these, 1,980 students responded, for a response rate of 73.8 percent. Most of the students reported preferring lectures with the aid of PowerPoint and chalkboard. They preferred morning lectures from 8 am to 10 am for a maximum of thirty to forty minutes for each lecture, and they preferred to receive information about the lecture topic in advance. The students said that delivery of clinical demonstrations was beneficial after the lectures, and they preferred learning-based rather than exam-oriented education. The respondents also said that attendance should be made compulsory and that numerical marking of examinations should not be replaced by a grading system.

Training in intercultural competency for health care professionals is necessary to bring greater balance to the disparity currently found among those needing health care. The purpose of this study was to determine what, if any, improvements in cultural competency were measurable in physician assistant (PA) students as they matriculated, using the Multicultural Awareness, Knowledge and Skills Survey-Revised as a pretest upon program entry and again as a posttest on the final day of the program. Ninety-three PA students from four successive classes graduating from a private midwest college between 2003 and 2007 participated in the pre and post measurements. All students were enrolled in specific didactic studies and clinical experiences in cultural sensitivity and competency. The results demonstrated significant improvement in knowledge (pretest 2.63, posttest 2.76, p=0.001) and skills (pretest 2.63, posttest 2.93, p<0.001) for all classes combined. The Intercultural Development Inventory was administered to the most recent graduating class to further explore these results. This cohort showed the highest scores (group mean 3.58 on scale of 1-5) in the Minimization developmental stage, which emphasizes cultural commonality over cultural distinctions. Enhanced curricular instruction such as exploring cultural assessment methods and controversies in health care differences, combined with increased clinical experiences with diverse cultures, are recommended to help move students past the minimization stage to gain greater cultural competency.

2012-10-01

The SPIE/OSA Student Chapter at Michigan Technological University have developed demonstrations and workshops for science and engineering outreach. The practical approach to holography promotes the study of photonic related sciences in high school and college-aged students. An introduction to laser safety, optical laboratory practices, and basic laser coherence theory is given in order to first introduce the participants to the science behind the holograms. The students are then able to create a hologram of an item of their choice, personalizing the experience. By engaging directly, the students are able to see how the theory is applied and also enforces a higher level of attention from them so no mistakes are made in their hologram. Throughout the course participants gain an appreciation for photonics by learning how holograms operate and are constructed through hands on creation of their own holograms. This paper reviews the procedures and methods used in the demonstrations and workshop while examining the overall student experience.

2005-09-01

This is a variation on the String and Sticky Tape demonstration "The Wave Game," suggested by Ron Edge. A group of students stand side by side, each one holding a card chest high with both hands. The teacher cues the first student to begin raising and lowering his card. When he starts lowering his card, the next student begins to raise his. As succeeding students move their cards up and down, a wave such as that shown in the figure is produced. To facilitate the process, students' motions were synchronized with the ticks of a metronome (without such synchronization it was nearly impossible to generate a satisfactory wave). Our waves typically had a frequency of about 1 Hz and a wavelength of around 3 m. We videotaped the activity so that the students could analyze the motions. The (17-year-old) students had not received any prior instruction regarding wave motion and did not know beforehand the nature of the exercise they were about to carry out. During the activity they were asked what a transverse wave is. Most of them quickly realized, without teacher input, that while the wave propagated horizontally, the only motion of the transmitting medium (them) was vertical. They located the equilibrium points of the oscillations, the crests and troughs of the waves, and identified the wavelength. The teacher defined for them the period of the oscillations of the motion of a card to be the total time for one cycle. The students measured this time and then several asserted that it was the same as the wave period. Knowing the length of the waves and the number of waves per second, the next step can easily be to find the wave speed.

Depth cue reliance in surgeons and medical students.

PubMed

Shah, J; Buckley, D; Frisby, J; Darzi, A

2003-09-01

Depth perception is reduced in endoscopic surgery, although little is known about the effect this has on surgical performance. To assess the role of depth cues, 45 subjects completed tests of depth cue reliance. Surgical skill was assessed using the Minimally Invasive Surgical Trainer-Virtual Reality, a previously validated laparoscopic simulator. We could demonstrate no difference in cue reliance for three depth cues--namely stereo, texture, and outline--between surgeons and medical students. Greater dominance on stereo for medical students was a positive finding and a negative finding for the surgeons when correlated with surgical performance. We suggest that surgeons learn to adapt to the nonstereo environment in MIS, and this is the first study to show evidence of this phenomenon. This difference in stereo reliance is a reflection of the experience that surgeons have with laparoscopy compared with medical students, who have none.

Science inquiry and student diversity: Enhanced abilities and continuing difficulties after an instructional intervention

Lee, Okhee; Buxton, Cory; Lewis, Scott; Leroy, Kathryn

2006-09-01

This study examines elementary students' abilities to conduct science inquiry through their participation in an instructional intervention over a school year. The study involved 25 third and fourth grade students from six elementary schools representing diverse linguistic and cultural groups. Prior to and at the completion of the intervention, the students participated in elicitation sessions as they conducted a semistructured inquiry task on evaporation. The results indicate that students demonstrated enhanced abilities with some aspects of the inquiry task, but continued to have difficulties with other aspects of the task even after instruction. Although students from all demographic subgroups showed substantial gains, students from non-mainstream and less privileged backgrounds in science showed greater gains in inquiry abilities than their more privileged counterparts. The results contribute to the emerging literature on designing learning environments that foster science inquiry of elementary students from diverse backgrounds.

Greater tactile sensitivity and less use of immature psychological defense mechanisms predict women's penile-vaginal intercourse orgasm.

PubMed

Brody, Stuart; Houde, Stephanie; Hess, Ursula

2010-09-01

Previous research has suggested that diminished tactile sensitivity might be associated with reduced sexual activity and function. Research has also demonstrated significant physiological and psychological differences between sexual behaviors, including immature psychological defense mechanisms (associated with various psychopathologies) impairing specifically women's orgasm from penile-vaginal intercourse (PVI). To examine the extent to which orgasm triggered by PVI (distinguished from other sexual activities) is associated with both greater tactile sensitivity and lesser use of immature psychological defenses. Seventy French-Canadian female university students (aged 18-30) had their finger sensitivity measured with von Frey type microfilaments, completed the Defense Style Questionnaire and a short form of the Marlowe-Crowne social desirability scale, and provided details of the 1 month (and ever) frequencies of engaging in, and having an orgasm from, PVI, masturbation, anal intercourse, partner masturbation, and cunnilingus. Logistic and linear regression prediction of orgasm triggered by PVI from tactile sensitivity, age, social desirability responding, and immature psychological defenses. Having a PVI orgasm in the past month was associated with greater tactile sensitivity (odds ratio=4.0 for each filament point) and less use of immature defense mechanisms (odds ratio=5.1 for each scale point). Lifetime PVI orgasm was associated only with less use of immature defense mechanisms (and lower social desirability responding score). Orgasms triggered by other activities were not associated with either tactile sensitivity or immature defense mechanisms.

To compare medical students' skills for vaginal operative delivery by vacuum extraction (VE) after hands-on training versus video demonstration. We randomized medical students to an expert demonstration (group 1) or a hands-on (group 2) training using a standardized VE algorithm on a pelvic training model. Students were tested with a 40-item Objective Structured Assessment of Technical Skills (OSATS) scoring system after training and 4 days later. OSATS scores were the primary outcome. Performance time, self-assessment, confidence, and global rating scale were secondary outcomes. We assessed the constructive validity of OSATS in this VE model comparing metric scores of experts and students. In all, 137 students were randomized. OSATS scores were higher in group 2 (n = 63) compared with group 1 (n = 74) (32.89 ± 6.39 vs 27.51 ± 10.27, respectively; P < 0.0001). Global rating scale (1.49 ± 0.76 vs 2.33 ± 0.94, respectively; P < 0.0001), confidence (2.22 ± 0.75 vs 3.26 ± 0.94, respectively; P = 0.04), self-assessment (2.03 ± 0.62 vs 2.51 ± 0.77, respectively; P < 0.0001), and performance time (38.81 ± 11.58 seconds vs 47.23 ± 17.35 seconds, respectively; P = 0.001) also favored group 2. After 4 days, this effect persisted with OSATS scores still being significantly higher in group 2 (30.00 ± 6.50 vs 25.59 ± 6.09, respectively; P = 0.001). The assessed OSATS scores showed constructive validity. In a multiple linear regression analysis, group assignment independently influenced OSATS scores, whereas sex, handedness, sports activities, and type of curriculum were not independently associated with OSATS scores. Hands-on training is superior to video demonstration for teaching VE on a pelvic model.

2014-01-01

Purpose: The Community Clinical Oncology Program (CCOP) and Minority-Based Community Clinical Oncology Program (MBCCOP) are provider-based research networks (PBRN) that improve minority enrollment in cancer-focused clinical trials. We hypothesized that affiliation with a PBRN may also mitigate racial differences in hospice enrollment for patients with lung cancer. Methods: We used the SEER-Medicare data, linked to the National Cancer Institute's CCOP program data, to identify all patients (≥ age 65 years) with lung cancer, diagnosed from 2001 to 2007. We defined clinical treatment settings as CCOP, MBCCOP, academic, or community-affiliated and used multivariable logistic regression analysis to determine factors associated with hospice enrollment. Results: Forty-one thousand eight hundred eighty-five (55.1%) patients with lung cancer enrolled in hospice before death. Approximately 55% of CCOP, 57% of MBCCOP, 57% of academic, and 52% of community patients enrolled. Patients who were more likely to enroll were female (odds ratio [OR], 1.36; 95% CI, 1.31 to 1.40); ≥ age 79 years (OR, 1.11; 95%CI, 1.06 to 1.16); white; lived in more educated areas; had minimal comorbidities; and had distant disease. Asian and black patients in academic (41.1% and 50.4%, respectively) and community practices (35.2% and 43.4%, respectively) were less likely to enroll in hospice compared with white patients (academic, 58.8%; community, 53.1%). However, hospice enrollment was equivalent for black and white patients in MBCCOP (59.5% v 57.2%) and CCOP (52.2% v 56.3%) practices. Conclusion: Minority patients with lung cancer receiving treatment in cancer-focused PBRN- affiliated practices have greater hospice enrollment than those treated in academic and community practices.

2013-01-01

The present study investigated the significance of auditory discrimination and the use of phonological and orthographic codes during the course of reading development in Chinese students who are deaf or hard of hearing (D/HH). In this study, the reading behaviors of D/HH students in 2 tasks-a task on auditory perception of onset rime and a synonym decision task-were compared with those of their chronological age-matched and reading level (RL)-matched controls. Cross-group comparison of the performances of participants in the task on auditory perception suggests that poor auditory discrimination ability may be a possible cause of reading problems for D/HH students. In addition, results of the synonym decision task reveal that D/HH students with poor reading ability demonstrate a significantly greater preference for orthographic rather than phonological information, when compared with the D/HH students with good reading ability and their RL-matched controls. Implications for future studies and educational planning are discussed.

University science students' knowledge of fats.

PubMed

Mazier, M J Patricia; McLeod, Sheena L

2007-01-01

Students entering university often lack knowledge about fats; whether students gain such information during four years at university is unclear. Students' knowledge of fat in the first and fourth years was measured and compared. The effect of a nutrition course on knowledge was also examined. A total of 215 science students at a small undergraduate university completed a 15-item, closed-ended questionnaire concerning knowledge of fats in the diet. Fourth-year science students have greater nutrition knowledge of fats than do first-year science students (p<0.005). Given that the majority of first-year students reside on campus and the majority of fourth-year students reside off campus, the purchasing of food and preparation of meals may explain the senior students' greater knowledge of fat. Students who have taken a nutrition course know more about fats than do those who have not (p<0.001). Taking even one course in nutrition greatly increases nutrition knowledge. Universities could encourage undergraduate students to take a basic nutrition course, which should emphasize the identification and understanding of different types of dietary fats.

Direct Demonstration of the Greenhouse Effect

NASA Astrophysics Data System (ADS)

Jaffe, D. A.; Malashanka, S.; Call, K.; Bernays, N.

2012-12-01

Consider these three "theories:" climate change, evolution, and gravity. Why are two of them hotly debated by non-scientists, but not gravity? In part, the answer is that climate change and evolution are more complex processes and not readily observable over short time scales to most people. In contrast, the "theory of gravity" is tested every day by billions of people world-wide and is therefore not challenged. While there are numerous "demonstrations" of the greenhouse effect available online, unfortunately, many of them are based on poor understanding of the physical principles involved. For this reason, we sought to develop simple and direct experiments that would demonstrate aspects of the greenhouse effect that would be suitable for museums, K-12, and/or college classrooms. We will describe two experiments. In the first, we use a simple plexiglass tube, approximately 12 cm long, with IR transparent windows. The tube is first filled with dry nitrogen and exposed to an IR heat lamp. Following this, the tube is filled with pure, dry CO2. Both tubes warm up, but the tube filled with CO2 ends up about 0.7 degrees C warmer. It is useful to compare this 12 cm column of CO2 to the column in the earth's atmosphere, which is equivalent to approximately 2.7 meters of pure CO2. This demonstration would be suitable for museum exhibits to demonstrate the physical basis of CO2 heating in the atmosphere. In the second experiment, we use FTIR spectroscopy to quantify the CO2 content of ambient air and indoor/classroom air. For this experiment, we use a commercial standard of 350 ppm CO2 to calibrate the absorption features. Once the CO2 content of ambient air is found, it is useful for students to compare their observed value to background data (e.g. NOAA site in Hawaii) and/or the "Keeling Curve". This leads into a discussion on causes for local variations and the long-term trends. This experiment is currently used in our general chemistry class but could be used in many

Demonstrating the unit hydrograph and flow routing processes involving active student participation - a university lecture experiment

NASA Astrophysics Data System (ADS)

Schulz, Karsten; Burgholzer, Reinhard; Klotz, Daniel; Wesemann, Johannes; Herrnegger, Mathew

2018-05-01

The unit hydrograph (UH) has been one of the most widely employed hydrological modelling techniques to predict rainfall-runoff behaviour of hydrological catchments, and is still used to this day. Its concept is based on the idea that a unit of effective precipitation per time unit (e.g. mm h-1) will always lead to a specific catchment response in runoff. Given its relevance, the UH is an important topic that is addressed in most (engineering) hydrology courses at all academic levels. While the principles of the UH seem to be simple and easy to understand, teaching experiences in the past suggest strong difficulties in students' perception of the UH theory and application. In order to facilitate a deeper understanding of the theory and application of the UH for students, we developed a simple and cheap lecture theatre experiment which involved active student participation. The seating of the students in the lecture theatre represented the hydrological catchment in its size and form. A set of plastic balls, prepared with a piece of magnetic strip to be tacked to any white/black board, each represented a unit amount of effective precipitation. The balls are evenly distributed over the lecture theatre and routed by some given rules down the catchment to the catchment outlet, where the resulting hydrograph is monitored and illustrated at the black/white board. The experiment allowed an illustration of the underlying principles of the UH, including stationarity, linearity, and superposition of the generated runoff and subsequent routing. In addition, some variations of the experimental setup extended the UH concept to demonstrate the impact of elevation, different runoff regimes, and non-uniform precipitation events on the resulting hydrograph. In summary, our own experience in the classroom, a first set of student exams, as well as student feedback and formal evaluation suggest that the integration of such an experiment deepened the learning experience by

Peer-to-Peer Instruction with Interactive Demonstrations in Upper Level Astronomy Courses

NASA Astrophysics Data System (ADS)

Gelderman, Richard

2013-06-01

Spectral and polarization properties of light are topics that most intro physics courses barely touch. Students therefore rarely have any useful experience to draw on when those topics come up in an upper level astronomy class. This means that they approach problems dealing with spectra or polarization as plug-and-chug mathematics applications, devoid of physical context. We have been addressing such dilemmas by using interactive demonstrations in the lecture meeting to give students direct experience with polarization filters, diffraction gratings, spectral sources, and situations requiring them to analyze sources based on the observed polarization of spectral properties. Each student individually predicts the outcomes for a demonstration. Students then collaborate within in a group of three to discuss their prediction, reporting the group’s consensus prediction. After observing the demonstration, students in the group compare their predictions to the results, and attempt to explain the phenomena. Based on curricular reforms in physics education, these methods have provided our students with the ability to much more than just manipulate equations related to spectroscopic and polarization analysis.

Passengers' perception of the safety demonstration on board an aircraft

NASA Astrophysics Data System (ADS)

Ruenruoy, Ratchada

The cabin safety demonstration on board an aircraft is one of the methods to provide safety information for passengers before aircraft takeoff. However, passengers' enthusiasm toward safety demonstrations is normally low. Therefore, the study of passengers' perception toward safety briefings on board an aircraft is important in increasing the safety awareness for the travelling public on commercial aircraft. A survey was distributed to measure the perceptions of Middle Tennessee State University (MTSU) faculty and staff, Aerospace students, and international students who have traveled in the last year. It was generally found that watching the cabin safety demonstration before aircraft takeoff was believed to be important for passengers. However, the attention to the safety demonstration remained low because the safety briefings were not good enough in terms of clear communication, particularly in the recorded audio demonstration and the live safety demonstration methods of briefing.

Various alternative methods are being used in many medical colleges to reinforce didactic lectures in physiology. Small group teaching can take on a variety of different tasks such as problem-solving, role play, discussions, brainstorming, and debate. Research has demonstrated that group discussion promotes greater synthesis and retention of materials. The aims of this study were to adopt a problem-solving approach by relating basic sciences with the clinical scenario through self-learning. To develop soft skills, to understand principles of group dynamics, and adopt a new teaching learning methodology. Experimental study design was conducted in Phase I 1(st) year medical students of 2014-2015 batch (n = 120). On the day of the session, the students were grouped into small groups (15 each). The session started with the facilitator starting off the discussion. Feedback forms from five students in each group was taken (n = 40). A five point Likert scale was used ranging from strongly agree to strongly disagree. Data were analyzed using IBM SPSS Statistics for Windows, Version 21.0. Armonk, NY: IBM Corp. Our results show that 70% of the students opined that small group discussion were interactive, friendly, innovative, built interaction between teacher and student. Small group discussion increased their thought process and helped them in better communication. The small group discussion was interactive, friendly, and bridged the gap between the teacher and student. The student's communication skills are also improved. In conclusion, small group discussion is more effective than the traditional teaching methods.

Demonstration models allow students to readily grasp theory and relate difficult concepts and equations to real life. However drawbacks of using these demonstration models are that they are can be costly to purchase from vendors or take a significant amount of time to build. These two limiting factors can pose a significant obstacle for adding demonstrations to the curriculum. This article presents an assignment to overcome these obstacles, which has resulted in 36 demonstration models being added to the curriculum. The article also presents the results of student performance on course objectives as a result of the developed models being used in the classroom. Overall, significant improvement in student learning outcomes, due to the addition of demonstration models, has been observed.

A Investigation of the Conceptual Changes Resulting from the Use of Demonstrations in College Physics.

NASA Astrophysics Data System (ADS)

Gattis, Kenneth William

1995-01-01

The purpose was to investigate the acquisition and retrieval of physics concepts introduced to college physics students by classroom demonstrations. Three experimental groups of calculus-based physics classes were presented lessons on three different topics during the semester. The lessons, which were planned to deliver identical concepts and examples, were preceded by a short quiz and were followed by an identical posttest. One treatment group received "enhanced" demonstration lessons, which included a brief period of peer discussion prior to the demonstration lesson. The second treatment group received typical demonstration lessons, and the control group received traditional lectures. Both demonstration groups were found to have higher conceptual gains than the control group on the topic of force and motion, which featured an air track demonstration. No differences were found on the topic of conservation of energy. On the topic of angular momentum, the demonstration groups tended to have higher prediction gains and the control group had higher explanation gains. No differences were found between the gains of the two demonstration groups. Student interview responses recorded one to two weeks after the experimental lessons indicated that the lesson containing a "stool and dumbbell" demonstration in the treatment groups was more memorable than the corresponding angular momentum lesson seen by the control group. Demonstration group students who made conceptual gains on the quizzes were found to give more complete responses to problems; yet they used language that was similar to that used by demonstration group students making no gains. In recalling experimental lessons, the demonstration group students gave responses that were more complete and used more everyday language than the control group students. It was concluded that demonstrations may assist students on certain topics by (1) helping to make concepts more believable; (2) helping to explain concepts that have

How Should Students Learn in the School Science Laboratory? The Benefits of Cooperative Learning

NASA Astrophysics Data System (ADS)

Raviv, Ayala; Cohen, Sarit; Aflalo, Ester

2017-07-01

Despite the inherent potential of cooperative learning, there has been very little research into its effectiveness in middle school laboratory classes. This study focuses on an empirical comparison between cooperative learning and individual learning in the school science laboratory, evaluating the quality of learning and the students' attitudes. The research included 67 seventh-grade students who undertook four laboratory experiments on the subject of "volume measuring skills." Each student engaged both in individual and cooperative learning in the laboratory, and the students wrote individual or group reports, accordingly. A total of 133 experiment reports were evaluated, 108 of which also underwent textual analysis. The findings show that the group reports were superior, both in terms of understanding the concept of "volume" and in terms of acquiring skills for measuring volume. The students' attitudes results were statistically significant and demonstrated that they preferred cooperative learning in the laboratory. These findings demonstrate that science teachers should be encouraged to implement cooperative learning in the laboratory. This will enable them to improve the quality and efficiency of laboratory learning while using a smaller number of experimental kits. Saving these expenditures, together with the possibility to teach a larger number of students simultaneously in the laboratory, will enable greater exposure to learning in the school science laboratory.

2012-01-01

This study investigated the effectiveness of a multicomponent reading intervention implemented with middle school students with severe reading difficulties, all of whom had received remedial and/or special education for several years with minimal response to intervention. Participants were 38 students in grades 6–8 who had severe deficits in word reading, reading fluency, and reading comprehension. Most were Spanish-speaking English language learners (ELLs) with identified disabilities. Nearly all demonstrated severely limited oral vocabularies in English and, for ELLs, in both English and Spanish. Students were randomly assigned to receive the research intervention (n = 20) or typical instruction provided in their school’s remedial reading or special education classes (n = 18). Students in the treatment group received daily explicit and systematic small-group intervention for 40 minutes over 13 weeks, consisting of a modified version of a phonics-based remedial program augmented with English as a Second Language practices and instruction in vocabulary, fluency, and comprehension strategies. Results indicated that treatment students did not demonstrate significantly higher outcomes in word recognition, comprehension, or fluency than students who received the school’s typical instruction and that neither group demonstrated significant growth over the course of the study. Significant correlations were found between scores on teachers’ ratings of students’ social skills and problem behaviors and posttest decoding and spelling scores, and between English oral vocabulary scores and scores in word identification and comprehension. The researchers hypothesize that middle school students with the most severe reading difficulties, particularly those who are ELLs and those with limited oral vocabularies, may require intervention of considerably greater intensity than that provided in this study.

Wheat is an important food security crop in central Asia but frequently suffers severe damage and yield losses from insect pests, pathogens, and weeds. With funding from the United States Agency for International Development, a team of scientists from three U.S. land-grant universities in collaboration with the International Center for Agricultural Research in Dry Areas and local institutions implemented an integrated pest management (IPM) demonstration program in three regions of Tajikistan from 2011 to 2014. An IPM package was developed and demonstrated in farmer fields using a combination of crop and pest management techniques including cultural practices, host plant resistance, biological control, and chemical approaches. The results from four years of demonstration/research indicated that the IPM package plots almost universally had lower pest abundance and damage and higher yields and were more profitable than the farmer practice plots. Wheat stripe rust infestation ranged from 30% to over 80% in farmer practice plots, while generally remaining below 10% in the IPM package plots. Overall yield varied among sites and years but was always at least 30% to as much as 69% greater in IPM package plots. More than 1,500 local farmers—40% women—were trained through farmer field schools and field days held at the IPM demonstration sites.

Wheat is an important food security crop in central Asia but frequently suffers severe damage and yield losses from insect pests, pathogens, and weeds. With funding from the United States Agency for International Development, a team of scientists from three U.S. land-grant universities in collaboration with the International Center for Agricultural Research in Dry Areas and local institutions implemented an integrated pest management (IPM) demonstration program in three regions of Tajikistan from 2011 to 2014. An IPM package was developed and demonstrated in farmer fields using a combination of crop and pest management techniques including cultural practices, host plant resistance, biological control, and chemical approaches. The results from four years of demonstration/research indicated that the IPM package plots almost universally had lower pest abundance and damage and higher yields and were more profitable than the farmer practice plots. Wheat stripe rust infestation ranged from 30% to over 80% in farmer practice plots, while generally remaining below 10% in the IPM package plots. Overall yield varied among sites and years but was always at least 30% to as much as 69% greater in IPM package plots. More than 1,500 local farmers-40% women-were trained through farmer field schools and field days held at the IPM demonstration sites. In addition, students from local agricultural universities participated in on-site data collection. The IPM information generated by the project was widely disseminated to stakeholders through peer-reviewed scientific publications, bulletins and pamphlets in local languages, and via Tajik national television.

Using Food to Demonstrate Earth Science Concepts

Walter, J.; Francek, M.

2001-12-01

One way to better engage K-16 students with the earth sciences is through classroom demonstrations with food. We summarize references from journals and the world wide web that use food to illustrate earth science concepts. Examples of how edible substances have been used include using candy bars to demonstrate weathering concepts, ice cream to mimic glaciers, and grapes to demonstrate evaporation. We also categorize these demonstrations into geology, weather, space science, and oceanography categories. We further categorize the topics by grade level, web versus traditional print format, amount of time necessary to prepare a lesson plan, and whether the activity is better used as a demonstration or hands on activity.

Emerging technologies and student information technology literacy are enabling new methods of teaching and learning for clinical skill performance. Facilitating experiential practice and reflection on performance through student self-video, and exposure to peer benchmarks, may promote greater levels of skill competency. This study examines the impact of student self-video on the attainment of clinical skills. A total of 60 Physiotherapy students (100%) consented to participate in the randomised controlled trial. One group (50%) was taught a complex clinical skill with regular practical tutoring, whilst the other group (50%) supplemented the tutoring with a self-video task aimed at promoting reflection on performance. Student skill performance was measured in an objective structured clinical examination (OSCE). Students also completed an anonymous questionnaire, which explored their perception of their learning experiences. Students received significantly higher scores in the OSCE when the examined clinical skill had been supplemented with a self-video of performance task (P = 0.048). Descriptive analysis of the questionnaires relating to student perceptions on the teaching methods identified that the self-video of performance task utilised contributed to improvement in their clinical performance and their confidence for future clinical practice. Students identified a number of aspects of the submission process that contributed to this perception of educational value. The novel results of this study demonstrate that greater clinical skill competency is achieved when traditional tutoring methods are supplemented with student self-video of performance tasks. Additional benefits included the ability of staff and students to monitor longitudinal performance, and an increase in feedback opportunities.

A popular demonstration involves placing a yo-yo on a level table and gently pulling the string horizontally when it is wrapped to come out below the center of the yo-yo's axis. Students are then asked to predict which way the yo-yo will move. A similar demonstration is performed with a tricycle by pulling forward on a pedal with the pedal down in its lowest position.2,3 As well as pulling the yo-yo horizontally, often the string is lifted until the angle it makes with the table causes no motion. This occurs when the line extended from the string intersects the point of contact of the yo-yo with the table.4 This paper describes an apparatus that extends these demonstrations to the situation where the force pulling the yo-yo is still horizontal yet is below the level of the table.

Nursing management needs to demonstrate its commitment to clinical education for undergraduate nursing students. The vision for the nursing leadership and management team at Princess Alexandra Hospital is to guide and support the development of hospital clinicians, at all levels in the organization, to effectively facilitate undergraduate students' learning during their clinical practical experiences. This paper examines the evolution of the meaning, commitment and practices that have been intrinsic to the development of strategic partnerships between the health-care organization and tertiary institutions to ensure that hospital staff who consistently facilitate student learning in the clinical context are well supported. The partnerships are based on open channels of communication between the health-care organization and the tertiary institutions whereby each party identifies its needs and priorities. This has resulted in increased hospital staff satisfaction through greater involvement by them in the placements of students, and enhanced understanding of clinicians of the student placement process that has contributed to improved satisfaction and outcomes for the students.

In 1996, CMS launched the end stage renal disease (ESRD) managed care demonstration to study the experience of offering managed care to ESRD patients. This article analyzes the financial impact of the demonstration, which sought to assess its economic impact on the Federal Government, the sites, and the ESRD Medicare beneficiaries. Medicare's costs for demonstration enrollees were greater than they would have been if these enrollees had remained in the fee-for-service (FFS) system. This loss was driven by the lower than average predicted Medicare spending given the demonstration patients' conditions. The sites experienced losses or only modest gains, primarily because they provided a larger benefit package than traditional Medicare coverage, including no patient obligations and other benefits, especially prescription drugs. Patient financial benefits were approximately $9,000 annually. PMID:14628400

2017-01-01

Background and Objectives Relatively little is known about the neuropsychological profiles of college students who misuse prescription stimulant medications. Methods Data presented are from college students aged 18 to 28 years who misused prescription stimulants prescribed for attention-deficit/hyperactivity disorder and controls (no prescription stimulant misuse). Students were assessed neuropsychologically using the self-report Behavioral Rating Inventory of Executive Functioning (BRIEF-A), the Cambridge Automated Neuropsychological Test and Battery (CANTAB), and other tests of cognitive functioning. The analyses included 198 controls (age 20.7 ± 2.6 years) and 100 prescription stimulant misusers (age 20.7 ± 1.7 years). Results On the BRIEF-A, misusers were more likely than controls to endorse greater dysfunction on 8 of 12 measures including Inhibition, Self Monitor, Initiation, Working Memory, and Plan/Organize, when adjusting for race and sex (all p’s <0.05). Similarly, when dichotomizing the BRIEF-A as abnormal (T score ≥ 65), misusers had more abnormalities on 5 of 9 subscales, as well as all major indices (p’s<0.05). Misusers also performed worse on several subtests of the CANTAB and standardized cognitive battery (p’s <0.05). A proxy of prescription stimulant misuse frequency was positively correlated with greater executive dysfunction on the BRIEF-A. Discussion and Conclusions These data demonstrate elevated risk for neuropsychological dysfunction among students who misuse prescription stimulants compared to non-misusing peers. The presence of ADHD contributed significantly to these cognitive findings. Students who misuse prescription stimulants should be screened for neuropsychological dysfunction. Scientific Significance These data may better elucidate the neuropsychological profile of college-aged prescription stimulant misusers. PMID:28494131

Critical classroom structures for empowering students to participate in science discourse

Belleau, Shelly N.; Otero, Valerie K.

2013-01-01

We compared contextual characteristics that impacted the nature and substance of "summarizing discussions" in a physics and a chemistry classroom in an Hispanic-serving urban high school. Specifically, we evaluated structural components of curricula and classrooms necessary to develop a culture of critical inquiry. Using the Physics and Everyday Thinking (PET) curriculum in the physics course, we found that students demonstrated critical thinking, critical evaluation, and used laboratory evidence to support ideas in whole-class summarizing discussions. We then implemented a model similar to PET in the chemistry course. However, chemistry students' statements lacked evidence, opposition and critical evaluation, and required greater teacher facilitation. We hypothesize that the designed laboratories and the research basis of PET influenced the extent to which physics students verbalized substantive scientific thought, authentic appeals to evidence, and a sense of empowerment to participate in the classroom scientific community.

Langfield, Tracey; Colthorpe, Kay; Ainscough, Louise

2017-12-04

Allied health professionals concur that a sound knowledge of practical gross anatomy is vital for the clinician, however, human anatomy courses in allied health programs have been identified as high-risk for attrition and failure. While anatomists and clinicians agree that learning anatomy via human cadaveric instruction is the preferred method, students vary in their reaction to the cadaveric learning experience and have differing levels of anatomy self-efficacy. This study investigated whether student self-efficacy had an effect on student usage of supplemental instructional videos and whether the use of videos had an impact on student self-efficacy and/or learning. Anatomy self-efficacy differed based on gender and prior performance. Student usage of the videos varied widely and students with lower self-efficacy were more inclined to use the resources. The provision of the videos did not improve overall cohort performance as compared to a historical cohort, however, those students that accessed all video sets experienced a greater normalized learning gain compared to students that used none or one of the four sets of videos. Student reports and usage patterns indicate that the videos were primarily used for practical class preparation and revision. Potentially, the videos represent a passive mode of teaching whereas active learning has been demonstrated to result in greater learning gains. Adapting the videos into interactive tutorials which will provide opportunity for feedback and the development of students' self-evaluation may be more appropriate.

With a growing need for developing future physician scientists, identifying characteristics of medical students who are likely to benefit from research training programs is important. This study assessed if specific learning styles of medical students, participating in federally funded short-term research training programs, were associated with research self-efficacy, a potential predictor of research career success. Seventy-five first-year medical students from 28 medical schools, selected to participate in two competitive NIH-supported summer programs for research training in aging, completed rating scales to evaluate learning styles at baseline, and research self-efficacy before and after training. We examined associations of individual learning styles (visual-verbal, sequential-global, sensing-intuitive, and active-reflective) with students' gender, ranking of medical school, and research self-efficacy. Research self-efficacy improved significantly following the training programs. Students with a verbal learning style reported significantly greater research self-efficacy at baseline, while visual, sequential, and intuitive learners demonstrated significantly greater increases in research self-efficacy from baseline to posttraining. No significant relationships were found between learning styles and students' gender or ranking of their medical school. Assessments of learning styles may provide useful information to guide future training endeavors aimed at developing the next generation of physician-scientists. © 2014 Wiley Periodicals, Inc.

Abstract Background: To compare medical students’ skills for vaginal operative delivery by vacuum extraction (VE) after hands-on training versus video demonstration. Methods: We randomized medical students to an expert demonstration (group 1) or a hands-on (group 2) training using a standardized VE algorithm on a pelvic training model. Students were tested with a 40-item Objective Structured Assessment of Technical Skills (OSATS) scoring system after training and 4 days later. OSATS scores were the primary outcome. Performance time, self-assessment, confidence, and global rating scale were secondary outcomes. We assessed the constructive validity of OSATS in this VE model comparing metric scores of experts and students. Results: In all, 137 students were randomized. OSATS scores were higher in group 2 (n = 63) compared with group 1 (n = 74) (32.89 ± 6.39 vs 27.51 ± 10.27, respectively; P < 0.0001). Global rating scale (1.49 ± 0.76 vs 2.33 ± 0.94, respectively; P < 0.0001), confidence (2.22 ± 0.75 vs 3.26 ± 0.94, respectively; P = 0.04), self-assessment (2.03 ± 0.62 vs 2.51 ± 0.77, respectively; P < 0.0001), and performance time (38.81 ± 11.58 seconds vs 47.23 ± 17.35 seconds, respectively; P = 0.001) also favored group 2. After 4 days, this effect persisted with OSATS scores still being significantly higher in group 2 (30.00 ± 6.50 vs 25.59 ± 6.09, respectively; P = 0.001). The assessed OSATS scores showed constructive validity. In a multiple linear regression analysis, group assignment independently influenced OSATS scores, whereas sex, handedness, sports activities, and type of curriculum were not independently associated with OSATS scores. Conclusions: Hands-on training is superior to video demonstration for teaching VE on a pelvic model. PMID:28296771

Electrostatic demonstration of free-fall weightlessness

2015-05-01

The phenomena of free-fall weightlessness have been demonstrated to students for many years in a number of different ways. The essential basis of all these demonstrations is the fact that in free-falling, gravitationally accelerated systems, the weight force and weight-related forces (for example, friction and hydrostatic forces) disappear. In this article, an original electrostatic demonstration of weightlessness is presented. A charged balloon fixed at the opening of a plastic container cannot lift a light styrofoam sphere sitting on the bottom when the container is at rest. However, while the system is in free-fall, the sphere becomes weightless and the charged balloon is able to lift it electrostatically.

The need of understanding and teaching about wave-particle duality if light with gets more and more apparent in the background of the attention of modern physics. As early as the beginning of twentieth Century, Einstein dared to "deny" the development of a very perfect light electromagnetic theory, so that the quantum of light can be developed. In 1924, De Broglie put forward wave-particle duality if light to other micro particles and the concept of matter wave, pointed out that all micro particle has wave-particle duality. This is a very abstract concept for students, most college physics teaching all lack of demonstration about particle duality of light. The present article aims to contribute to demonstrate the wave-particle duality of light at the same time using a simple way based on fiber optical tweezers. It is hoped that useful lesson can be absorbed so that students can deepen the understanding of the particle and wave properties of light. To complement the demonstration experiment for this attribute light has momentum.

Greater decision-making competence is associated with greater expected-value sensitivity, but not overall risk taking: an examination of concurrent validity.

PubMed

Parker, Andrew M; Weller, Joshua A

2015-01-01

Decision-making competence reflects individual differences in the susceptibility to committing decision-making errors, measured using tasks common from behavioral decision research (e.g., framing effects, under/overconfidence, following decision rules). Prior research demonstrates that those with higher decision-making competence report lower incidence of health-risking and antisocial behaviors, but there has been less focus on intermediate processes that may impact real-world decisions, and, in particular, those implicated by normative models. Here we test the associations between measures of youth decision-making competence (Y-DMC) and one such process, the degree to which individuals make choices consistent with maximizing expected value (EV). Using a task involving hypothetical gambles, we find that greater EV sensitivity is associated with greater Y-DMC. Higher Y-DMC scores are associated with (a) choosing risky options when EV favors those options and (b) avoiding risky options when EV favors a certain option. This relationship is stronger for gambles that involved potential losses. The results suggest that Y-DMC captures decision processes consistent with standard normative evaluations of risky decisions.

Greater Physiological and Behavioral Effects of Interrupted Stress Pattern Compared to Daily Restraint Stress in Rats

Repeated stress can trigger a range of psychiatric disorders, including anxiety. The propensity to develop abnormal behaviors after repeated stress is related to the severity, frequency and number of stressors. However, the pattern of stress exposure may contribute to the impact of stress. In addition, the anxiogenic nature of repeated stress exposure can be moderated by the degree of coping that occurs, and can be reflected in homotypic habituation to the repeated stress. However, expectations are not clear when a pattern of stress presentation is utilized that diminishes habituation. The purpose of these experiments is to test whether interrupted stress exposure decreases homotypic habituation and leads to greater effects on anxiety-like behavior in adult male rats. We found that repeated interrupted restraint stress resulted in less overall homotypic habituation compared to repeated daily restraint stress. This was demonstrated by greater production of fecal boli and greater corticosterone response to restraint. Furthermore, interrupted restraint stress resulted in a lower body weight and greater adrenal gland weight than daily restraint stress, and greater anxiety-like behavior in the elevated plus maze. Control experiments demonstrated that these effects of the interrupted pattern could not be explained by differences in the total number of stress exposures, differences in the total number of days that the stress periods encompased, nor could it be explained as a result of only the stress exposures after an interruption from stress. These experiments demonstrate that the pattern of stress exposure is a significant determinant of the effects of repeated stress, and that interrupted stress exposure that decreases habituation can have larger effects than a greater number of daily stress exposures. Differences in the pattern of stress exposure are therefore an important factor to consider when predicting the severity of the effects of repeated stress on

How to make mathematics relevant to first-year engineering students: perceptions of students on student-produced resources

NASA Astrophysics Data System (ADS)

Loch, Birgit; Lamborn, Julia

2016-01-01

Many approaches to make mathematics relevant to first-year engineering students have been described. These include teaching practical engineering applications, or a close collaboration between engineering and mathematics teaching staff on unit design and teaching. In this paper, we report on a novel approach where we gave higher year engineering and multimedia students the task to 'make maths relevant' for first-year students. This approach is novel as we moved away from the traditional thinking that staff should produce these resources to students producing the same. These students have more recently undertaken first-year mathematical study themselves and can also provide a more mature student perspective to the task than first-year students. Two final-year engineering students and three final-year multimedia students worked on this project over the Australian summer term and produced two animated videos showing where concepts taught in first-year mathematics are applied by professional engineers. It is this student perspective on how to make mathematics relevant to first-year students that we investigate in this paper. We analyse interviews with higher year students as well as focus groups with first-year students who had been shown the videos in class, with a focus on answering the following three research questions: (1) How would students demonstrate the relevance of mathematics in engineering? (2) What are first-year students' views on the resources produced for them? (3) Who should produce resources to demonstrate the relevance of mathematics? There seemed to be some disagreement between first- and final-year students as to how the importance of mathematics should be demonstrated in a video. We therefore argue that it should ideally be a collaboration between higher year students and first-year students, with advice from lecturers, to produce such resources.

National policy statements increasingly espouse the delivery of comprehensive mental health services in schools. In response to the limited evidence supporting this recommendation, the purpose of this study was to assess the need for, and feasibility, desirability, and outcomes of a full model of comprehensive mental health services in 2 public elementary schools in inner-city neighborhoods. The program, based upon a national model for comprehensive school mental health services, comprised universal and indicated preventive as well as clinical interventions designed to target needs identified in a baseline screening survey. The program was implemented over 1 school year by mental health professionals in collaboration with school teachers. Mental health outcomes comparing baseline to follow-up data were assessed in multiple domains among students and teachers. After 1 year of intervention, students had significantly fewer mental health difficulties, less functional impairment, and improved behavior, and reported improved mental health knowledge, attitudes, beliefs, and behavioral intentions. Teachers reported significantly greater proficiency in managing mental health problems in their classrooms. School staff overwhelmingly endorsed satisfaction with the program. If the observed favorable findings from this pilot demonstration can be replicated in methodologically rigorous studies, additional support would be garnered for national policy recommendations about comprehensive school mental health services. © 2011, American School Health Association.

The direct anterior approach (DAA) for the treatment of total hip arthroplasty (THA) has gained popularity in recent years. Chip fractures of the greater trochanter are frequently seen, but the risk factors for such fractures are unknown. The study aimed to identify the risk factors for chip fractures in patients undergoing primary THA by the DAA during the surgeons' learning curve. From November 2011 to April 2015, the first experiences of three surgeons who performed 120 THAs by the DAA (120 hips; 40 cases per beginner surgeon) were included. The incidence of chip fracture of the greater trochanter, the size of the greater trochanter as measured by computed tomography, and the patients' characteristics were retrospectively investigated. After exclusion of 11 hips, the remaining 109 hips were investigated. Chip fracture of the greater trochanter was identified in 32 hips (29.4 %). Univariate analysis with and without fractures showed that the width and depth of the greater trochanter were statistically significant risk factors (p = 0.02 and p < 0.001, respectively). Multivariate analysis using a logistic regression model demonstrated that the depth of the greater trochanter was an independent risk factor for chip fracture of the greater trochanter (OR 1.725; 95 % CI 1.367-2.177; p < 0.001). The size of the greater trochanter was identified as a risk factor for chip fracture of the greater trochanter. Novice surgeons should pay attention to the size of the greater trochanter when performing THA by the DAA.

Increasing the Use of Student-Centered Pedagogies from Moderate to High Improves Student Learning and Attitudes about Biology.

PubMed

Connell, Georgianne L; Donovan, Deborah A; Chambers, Timothy G

2016-01-01

Student-centered strategies are being incorporated into undergraduate classrooms in response to a call for reform. We tested whether teaching in an extensively student-centered manner (many active-learning pedagogies, consistent formative assessment, cooperative groups; the Extensive section) was more effective than teaching in a moderately student-centered manner (fewer active-learning pedagogies, less formative assessment, without groups; the Moderate section) in a large-enrollment course. One instructor taught both sections of Biology 101 during the same quarter, covering the same material. Students in the Extensive section had significantly higher mean scores on course exams. They also scored significantly higher on a content postassessment when accounting for preassessment score and student demographics. Item response theory analysis supported these results. Students in the Extensive section had greater changes in postinstruction abilities compared with students in the Moderate section. Finally, students in the Extensive section exhibited a statistically greater expert shift in their views about biology and learning biology. We suggest our results are explained by the greater number of active-learning pedagogies experienced by students in cooperative groups, the consistent use of formative assessment, and the frequent use of explicit metacognition in the Extensive section. © 2016 G.

Core Surgical Trainees (CST) in the London (UK) Postgraduate School of Surgery receive clinical anatomy teaching in their first year of training, and, in their second year, give 30 sessions of anatomy teaching to medical and other students. This study set out to investigate the role of demonstrators from the perspective of the trainees. A focus group was convened to ascertain trainees' perspectives on demonstrating anatomy and to identify problems and improvement strategies to optimize their ability to enhance students' learning. A questionnaire was formulated and all second-year CST (n = 186-from two cohorts) in the London Postgraduate School of Surgery were invited. A total of 109 out of 186 trainees completed the questionnaire. A high percentage (98%) of trainees that completed the questionnaire responded that demonstrating was an invaluable part of their training. Sixty-two per cent responded that anatomy teaching they received in their first year of core surgical training helped them in their teaching role and 80% responded that it helped them prepare for surgical training. The study also revealed the need for improved communication between trainees and the London Postgraduate School of Surgery/Medical Schools/National Health Service Trusts to address issues such as trainees' perceived difficulty in fulfilling their teaching session requirement. The stakeholders have acknowledged and addressed the outcomes to improve the experience for both surgical trainees and students. The results indicate that anatomy demonstrating delivers important benefits to early surgical trainees, in addition to those received by the students that they teach. Clin.

It can be quite difficult to instill an intuitive sense of the scaling relationships for mantle convection to a class of geology students, but the use of various props can help. One favorite demonstration tool is the good old lava lamp which, coincidentally, first went on sale at the very time plate tectonic theory was gaining acceptance. Armed with one or more lava lamps, a lecturer can quickly impress upon students how scaling effects such as viscosity, heat input, gravitional acceleration influence the vigour of convection - a first step to understanding basic concepts such as Rayleigh number from a non-mathematical perspective. For more advanced students it is instructive to build a lava lamp for themselves because then it is necessary to understand the trade-off between chemical and thermal buoyancy, and how the equivalent scaling relationships to the purely thermal convection case play out. However, most of the recipes for lava lamps which you can find on the web involve the use of highly toxic substances, often flammable, and suggest the use of mains electricity to provide the light and heat. Needless to say, university safety officers and concerned parents are nervous about permitting such activities in student offices, dorms or at home. We share their concerns, of course, and here suggest a number of relatively safe alternatives which can be constructed from supermarket foodstuffs and cosmetic products together with heat sources such as a cappucino machine, a laptop running finite element simulations, as well as sealed chemical handwarmers.

Associations among bullying, cyberbullying, and suicide in high school students.

Bauman, Sheri; Toomey, Russell B; Walker, Jenny L

2013-04-01

This study examined associations among depression, suicidal behaviors, and bullying and victimization experiences in 1491 high school students using data from the 2009 Youth Risk Behavior Survey. Results demonstrated that depression mediated the association between bullying/victimization and suicide attempts, but differently for males and females. Specifically, depression mediated the link between traditional victimization and suicide attempts similarly across gender, whereas depression mediated the link between cyber victimization and suicide attempts only for females. Similarly, depression mediated the link between traditional bullying and suicide attempts for females only. Depression did not mediate the link between cyberbullying and suicide attempts for either gender. Implications of the findings are discussed, including the importance of greater detection of depression among students involved in bullying, and the need for a suicide prevention and intervention component in anti-bullying programs. Findings suggest that bullying prevention efforts be extended from middle school students to include high school students.

Higher motivation - greater control? The effect of arousal on judgement.

PubMed

Riemer, Hila; Viswanathan, Madhu

2013-01-01

This research examines control over the effect of arousal, a dimension of affect, on judgement. Past research shows that high processing motivation enhances control over the effects of affect on judgement. Isolating and studying arousal as opposed to valence, the other dimension of affect, and its effect on judgement, we identify boundary conditions for past findings. Drawing from the literature on processes by which arousal influences judgement, we demonstrate that the role of motivation is contingent upon the type of judgement task (i.e., memory- versus stimulus-based judgement). In stimulus-based judgement, individuals exert greater control over the effect of arousal on judgement under low compared to high motivation. In contrast, in memory-based judgement individuals exert greater control over the effect of arousal under high compared to low motivation. Theoretical implications and avenues for future research are discussed.

Analysis of social networks may be a useful tool for understanding the relationship between resilience and engagement, and this could be applied to educational methodologies, not only to improve academic performance, but also to create emotionally sustainable networks. This descriptive study was carried out on 134 university students. We collected the network structural variables, degree of resilience (CD-RISC 10), and engagement (UWES-S). The computer programs used were excel, UCINET for network analysis, and SPSS for statistical analysis. The analysis revealed results of means of 28.61 for resilience, 2.98 for absorption, 4.82 for dedication, and 3.13 for vigour. The students had two preferred places for sharing information: the classroom and WhatsApp. The greater the value for engagement, the greater the degree of centrality in the friendship network among students who are beginning their university studies. This relationship becomes reversed as the students move to later academic years. In terms of resilience, the highest values correspond to greater centrality in the friendship networks. The variables of engagement and resilience influenced the university students' support networks.

Patient-centred care is an important aspect of quality health care. The learning environment may impact medical students' adoption of patient-centred behaviours. All medical students at a single institution received an anonymous, modified version of the Communication, Curriculum, and Culture instrument that measures patient-centredness in the training environment along three domains: role modelling, students' experience, and support for patient-centred behaviours. We compared domain scores and individual items by class year and gender, and qualitatively analyzed responses to two additional items that asked students to describe experiences that demonstrated varying degrees of patient-centredness. Year 1 and 2 students reported greater patient-centredness than year 3 and 4 students in each domain: role modelling (p = 0.03), students' experience (p = <0.001), and support for patient-centred behaviours (p < 0.001). Female students reported less support for patient-centred behaviours compared with male students (p = 0.03). Qualitative analysis revealed that explicit patient-centred curricula and positive role modelling fostered patient-centredness. Themes relating to low degrees of patient-centredness included negative role modelling and students being discouraged from being patient-centred. Students' perceptions of the patient-centredness of the learning environment decreased as students progressed through medical school, despite increasing exposure to patients. Qualitative analysis found that explicit patient-centred curricula cultivated patient-centred attitudes. Role modelling impacted student perceptions of patient-centredness within the learning environment.

An emerging model for sexuality education is the rights-based approach, which unifies discussions of sexuality, gender norms, and sexual rights to promote the healthy sexual development of adolescents. A rigorous evaluation of a rights-based intervention for a broad population of adolescents in the U.S. has not previously been published. This paper evaluates the immediate effects of the Sexuality Education Initiative (SEI) on hypothesized psychosocial determinants of sexual behavior. A cluster-randomized trial was conducted with ninth-grade students at 10 high schools in Los Angeles. Classrooms at each school were randomized to receive either a rights-based curriculum or basic sex education (control) curriculum. Surveys were completed by 1,750 students (N = 934 intervention, N = 816 control) at pretest and immediate posttest. Multilevel regression models examined the short-term effects of the intervention on nine psychosocial outcomes, which were hypothesized to be mediators of students' sexual behaviors. Compared with students who received the control curriculum, students receiving the rights-based curriculum demonstrated significantly greater knowledge about sexual health and sexual health services, more positive attitudes about sexual relationship rights, greater communication about sex and relationships with parents, and greater self-efficacy to manage risky situations at immediate posttest. There were no significant differences between the two groups for two outcomes, communication with sexual partners and intentions to use condoms. Participation in the rights-based classroom curriculum resulted in positive, statistically significant effects on seven of nine psychosocial outcomes, relative to a basic sex education curriculum. Longer-term effects on students' sexual behaviors will be tested in subsequent analyses. ClinicalTrials.gov NCT02009046.

Dramatic (and Simple!) Demonstration of Newton's Third Law

NASA Astrophysics Data System (ADS)

Feldman, Gerald

2011-02-01

An operational understanding of Newton's third law is often elusive for students. Typical examples of this concept are given for contact forces that are closer to the students' everyday experience. While this is a good thing in general, the reaction force can sometimes be taken for granted, and the students can miss the opportunity to really think about what is going on. In the case of magnetic forces, however, the notion of action at a distance actually requires a careful inspection of the forces involved and thereby promotes a more detailed analysis of the situation. In this paper, a simple demonstration of Newton's third law is presented in the context of a magnet falling through a hollow conducting tube. The results are unambiguous and lead the students to an irrefutable verification of Newton's third law.

Oral health of Rhodesia African first year student teachers.

PubMed

Ritchie, J

1979-08-01

A basic oral health survey was carried out on a random sample of first year African student teachers attending four teachers' colleges in Rhodesia. The number examined and interviewed was 309. Methods and criteria used are those described in the second (1977) edition of the World Health Organization manual Oral health surveys - Basic methods. Prevalences of dental caries were 31.0% for the 142 male students and 59.5% for the 167 female students. The difference is statistically significant (P less than 0.001). Mean DMFTs were 0.74 for men and 2.02 for women. The prevalences of "intense gingivitis" were 52.8% for male students and 34.7% for female students. This difference also is significant (P less than 0.005). The major treatment requirements are for one-surface fillings and prophylaxis with oral hygiene instruction. Dental service utilization is low. Less than 10% of the sample had obtained dental care in the previous 12 months. The main reason for seeking care was pain. Self-assessments of oral health needs were not valid. The stated desire for fillings is greater than for extractions. A need has been demonstrated for dental health education aimed at the prevention of disease and the encouragement, use and demand for quality care services.

Competitive sports are recognized as having unique health benefits and risks, and the effect of sports on life-span health among elite athletes has received increasing attention. However, supporting scientific data are sparse and do not represent modern athletes. To assess holistic life-span health and health-related quality-of-life (HRQL) among current and former National Collegiate Athletic Association student-athletes (SAs). Cross-sectional study. A large Division I university. Population-based sample of 496 university students and alumni (age 17-84 years), including SAs and an age-matched and sex-matched nonathlete (NA) control group. Participants completed anonymous, self-report questionnaires. We measured the Short-Form 12 (SF-12) physical and mental component HRQL scores and cumulative lifetime experience and relative risk of treatment for joint, cardiopulmonary, and psychosocial health concerns. Older alumni (age 43+ years) SAs reported greater joint health concerns than NAs (larger joint summary scores; P = .04; Cohen d = 0.69; probability of clinically important difference [pCID] = 77%; treatment odds ratio [OR] = 14.0, 95% confidence interval [CI] = 1.6, 126). Joint health for current and younger alumni SAs was similar to that for NAs. Older alumni reported greater cardiopulmonary health concerns than younger alumni (summary score P < .001; d = 1.05; pCID = 85%; OR = 5.8, 95% CI = 2.0, 16) and current students (P < .001; d = 2.25; pCID >99.5%; OR = 7.1, 95% CI = 3.3, 15), but the risk was similar for SAs and NAs. Current SAs demonstrated evidence of better psychosocial health (summary score P = .006; d = -0.52; pCID = 40%) and mental component HRQL (P = .008; d = 0.50; pCID = 48%) versus NAs but similar psychosocial treatment odds (OR = 0.87, 95% CI = 0.39, 1.9). Psychosocial health and mental component HRQL were similar between alumni SAs and NAs. No differences were observed between SAs and NAs in physical component HRQL. The SAs demonstrated

Complex social, racial, economic, and political issues involved in the practice of teaching today require beginning teachers to be informed, skilled, and culturally responsive when entering the classroom. Teacher educators must educate future teachers in ways that will help them teach all children regardless of language, cultural background, or prior knowledge. The purpose of this study was to explore the extent to which culturally and linguistically diverse (CLD) novice teachers described and demonstrated culturally responsive teaching strategies using their students' cultural and academic profiles to inform practice in science and mathematics instruction. This qualitative exploratory case study considered the culturally responsive teaching practices of 12, non-traditional, Latina/o students as they progressed through a distance-based collaborative teacher education program. Qualitative techniques used throughout this exploratory case study investigated cultural responsiveness of these student teachers as they demonstrated their abilities to: a) integrate content and facilitate knowledge construction; b) illustrate social justice and prejudice reduction; and c) develop students academically. In conclusion, student teachers participating in this study demonstrated their ability to integrate content by: (1) including content from other cultures, (2) building positive teacher-student relationships, and (3) holding high expectations for all students. They also demonstrated their ability to facilitate knowledge construction by building on what students knew. Since there is not sufficient data to support the student teachers' abilities to assist students in learning to be critical, independent thinkers who are open to other ways of knowing, no conclusions regarding this subcategory could be drawn. Student teachers in this study illustrated prejudice reduction by: (1) using native language support to assist students in learning and understanding science and math content

2008-11-01

This paper examines the experiences of nursing students undertaking an international placement during their pre-registration education. The study took place in two schools--one in the United Kingdom, and one in Sweden. The move of nursing education into higher education enabled students to participate in international exchange programmes. Previous research demonstrates that students participating in such programmes may gain enhanced cultural awareness and experience personal and professional growth. The study comprised a multiple case study, utilising semi-structured individual and group interviews and documentary analysis. Eighteen students from the UK and 14 from Sweden participated. Participants described an increase in confidence, self-reliance and professional knowledge and skills resulting from their international placement. There was an awareness of how healthcare roles differ between countries and a change in attitudes to others from different backgrounds and cultures. The differences between the two cases were marginal. Whilst there was support from both home and host universities this varied between the international placement providers. The international placements were beneficial; however, there is a need for change in the preparation, support and monitoring of students, greater engagement with the partner institutions, and more effective mentoring of staff.

Alcohol use is reported in university students with discrepancy between countries. The study objectives were to assess prevalence and associated factors of alcohol consumption among university students in Germany and China. Data used were from 1853 Chinese and 3306 German university students. Alcohol consumption frequency was measured by a question "How often did you drink alcohol in the last three months?" with six possible responses, which were later collapsed into three categories of "At least once a week", "Less than once a week" and "Never". Problem drinking was measured by the CAGE test and defined as a CAGE score of two or more (four as the maximum). Simple and multivariable logistic regressions were used for association analyses. German students reported more often "At least once a week" drinking (59.8 vs. 9.0 %). Among Germans, women drank less often "At least once a week" (OR = 0.40, 0.30-0.53). Among Chinese, a higher BMI was associated with drinking "At least once a week" (OR = 1.09, 1.02-1.18). Age revealed a positive association with "At least once a week" drinking in Chinese (1.33, 1.21-1.46) but a negative association in Germans (OR = 0.97, 0.94-0.99). Having a father with high educational level was positively related to "At least once a week" drinking in both countries (OR = 4.25, 2.67-6.78 for Chinese; OR = 1.32, 1.01-1.72 for Germans). Doing less than once a week physical exercise was negatively associated with "At least once a week" drinking in Chinese and German students (OR = 0.27, 0.15-0.48 for Chinese; OR = 0.69, 0.49-0.96 for Germans). Among the German students, 20.3 % reported problem drinking. Being a female (OR = 0.32, 0.26-0.40) and performing less than once a week physical activity (OR = 0.73, 0.56-0.95) were negatively associated with problem drinking, while having a father with high educational level (OR = 1.32, 1.09-1.60) and experiencing higher level of perceived stress (OR = 1.08, 1

2009-03-01

Launch into education about pharmacology (LEAP) is an inquiry-based science enrichment program designed to enhance competence in biology and chemistry and foster interest in science careers especially among under-represented minorities. The study of how drugs work, how they enter cells, alter body chemistry, and exit the body engages students to conceptualize fundamental precepts in biology, chemistry, and math. Students complete an intensive three-week course in the fundamentals of pharmacology during the summer followed by a mentored research component during the school year. Following a 5E learning paradigm, the summer course captures student interest by introducing controversial topics in pharmacology and provides a framework that guides them to explore topics in greater detail. The 5E learning cycle is recapitulated as students extend their knowledge to design and to test an original research question in pharmacology. LEAP students demonstrated significant gains in biology and chemistry knowledge and interests in pursuing science. Several students earned honors for the presentation of their research in regional and state science fairs. Success of the LEAP model in its initial 2 years argues that coupling college-level coursework of interest to teens with an authentic research experience enhances high school student success in and enthusiasm for science.

Pecor, Keith; Kang, Lilia; Henderson, Matthew; Yin, Sunny; Radhakrishnan, Varsha; Ming, Xue

2016-06-01

We tested for associations of bedtime, sleep duration, instant messaging, and chronic headaches with hypersomnolence and academic performance in a sample of high school students in New Jersey, USA. Students were surveyed anonymously and asked to report their sleep and messaging habits, headache status, and overall grades. We found that greater hypersomnolence was associated with later bedtimes, shorter sleep durations, and the presence of chronic headaches, but not with messaging after lights out. Also, we found that academic performance was lower in students who messaged after lights out, but it was not affected by headache status, bedtime, or sleep duration. These results are consistent with other studies that have demonstrated associations between headaches and hypersomnolence and between instant messaging habits and academic performance. They also add to a growing literature on the relationships among use of electronic devices, sleep health, and academic performance by adolescents.

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.

"Greater India" is an 80-yr-old concept that has been used by geoscientists in plate tectonic models of the India-Asia collision system. Numerous authors working on the orogen and/or plate models of the broader region have added various sized chunks of continental lithosphere to the now northern edge of their reconstructed Indian plate. Prior to plate tectonic theory, Emile Argand (1924) [Argand, E., 1924. La tectonique de l' Asie. Proc. 13th Int. Geol. Cong. 7 (1924), 171-372.] and Arthur Holmes (1965) [Holmes, A., 1965.

The Ronald Press Company, New York, 1128.] thought that the Himalayan Mountains and Tibetan Plateau had been raised due to the northern edge of the Indian craton under-thrusting the entire region. Since the advent of plate tectonic theory, Greater India proposals have been based principally on three lines of logic. One group of workers has added various amounts of continental lithosphere to India as part of their Mesozoic Gondwana models. A second form of reconstruction is based on Himalayan crustal-shortening estimates. A third body of researchers has used India continent extensions as means of allowing initial contact between the block and the Eurasian backstop plate in southern Tibet to take place at various times between the Late Cretaceous and late Eocene in what we call "fill-the-gap" solutions. The Indian craton and the southern edge of Eurasia were almost invariably some distance from one another when the collision was supposed to have started; extensions to the sub-continent were used to circumvent the problem. Occasionally, Greater India extensions have been based on a combination of fill-the-gap and shortening estimate arguments. In this paper, we exhume and re-examine the key Greater India proposals. From our analysis, it is clear that many proponents have ignored key information regarding the sub-continent's pre break-up position within Gondwana and the bathymetry of the Indian Ocean

Ishak, Zahari; Low, Suet Fin; Lau, Poh Li

2012-08-01

Parenting styles have always been a crucial factor in influencing all aspects of a person's development. The purpose of this study is to test the structural equation model of academic achievement among the students using parenting styles as a moderator. The sample comprised 493 students from eight schools. Parenting styles are determined using the Parental Authority Questionnaire (Buri in J Pers Assess 57:110-119, 1991). Academic achievement is measured based on the students' performance in the Lower Secondary Assessment. Data were analyzed using structural equation modelling. Results demonstrated that model of authoritative and model of authoritarian fit the data of this study well. Both authoritative and authoritarian parenting styles are the most common practice of the parents. Parenting styles have been found to be a moderator of this study. The results indicated that parenting styles moderated the effect of academic self-concept on academic achievement. The impact of academic self-concept on academic achievement is found to be greater for the authoritative than the authoritarian parenting style.

Discounting of Condom-Protected Sex as a Measure of High Risk for Sexually Transmitted Infection Among College Students.

PubMed

Collado, Anahí; Johnson, Patrick S; Loya, Jennifer M; Johnson, Matthew W; Yi, Richard

2017-10-01

The study examined sexual delay discounting, or the devaluation of condom-protected sex in the face of delay, as a risk factor for sexually transmitted infection (STI) among college students. Participants (143 females, 117 males) completed the sexual delay discounting task (Johnson & Bruner, 2012) and questionnaires of risky sexual behavior, risk perception, and knowledge. Participants exhibited steeper sexual delay discounting (above and beyond general likelihood of having unprotected sex) when partners were viewed as more desirable or less likely to have a STI, with males demonstrating greater sexual delay discounting than females across most conditions. Importantly, greater self-reported risky sexual behaviors were associated with higher rates of sexual delay discounting, but not with likelihood of using a condom in the absence of delay. These results provide support for considering sexual delay discounting, with particular emphasis on potential delays to condom use, as a risk factor for STI among college students.

Loudspeaker line array educational demonstration.

PubMed

Anderson, Brian E; Moser, Brad; Gee, Kent L

2012-03-01

This paper presents a physical demonstration of an audio-range line array used to teach interference of multiple sources in a classroom or laboratory exercise setting. Software has been developed that permits real-time control and steering of the array. The graphical interface permits a user to vary the frequency, the angular response by phase shading, and reduce sidelobes through amplitude shading. An inexpensive, eight-element loudspeaker array has been constructed to test the control program. Directivity measurements of this array in an anechoic chamber and in a large classroom are presented. These measurements have good agreement with theoretical directivity predictions, thereby allowing its use as a quantitative learning tool for advanced students as well as a qualitative demonstration of arrays in other settings. Portions of this paper are directed toward educators who may wish to implement a similar demonstration for their advanced undergraduate or graduate level course in acoustics. © 2012 Acoustical Society of America

Severinsson, Elisabeth; Sand, Ase

2010-09-01

The aim of the present study was to evaluate the clinical supervision and professional development of student nurses during their undergraduate education. Nursing education has undergone radical changes as a result of improvements in the academic-based clinical education required for the Bachelor's degree. The sample consisted of student nurses (n = 147) and data were collected by means of questionnaires. The results demonstrated that the frequency of sessions and the supervision model employed influence the student nurses' professional development. Several significant correlations were found, most of which were related to the development of the student nurses' professional relationships with their supervisors and reflection on the development of their skills. From the patients' perspective, a high correlation was found between the factors 'preserving integrity' and 'protecting participation by patients and family members'. Clinical supervision strongly influences the student nurses' development of a professional identity, enhancing decision-making ability and personal growth. However, development of documentation skills should include a greater level of user involvement. The findings highlight the need for management and staff nurses to engage in on-going professional development. Transformative leadership, which is value driven, can facilitate and enhance the supervision and development of student nurses. © 2010 The Authors.

Exploring ESL students' understanding of mathematics in the early years: factors that make a difference

NASA Astrophysics Data System (ADS)

Miller, Jodie; Warren, Elizabeth

2014-12-01

Students living in disadvantaged contexts and whose second language is English (ESL) are at risk of not succeeding in school mathematics. It has been internationally recognised that students' socioeconomic background and their achievements in mathematics is more pronounced for Australian students (Thomson et al. 2011). This gap is even more prominent for students who also have English as their second language (ESL). This paper explores the impact of the representations, oral language and engagement in mathematics (RoleM) learning experiences on ESL students' performance in mathematics in the early years (foundation-year 2). All students participating in the study are from disadvantaged contexts ( n = 461). The sample comprised 328 students who identified themselves as having English as a second language (ESL) and 133 mainstream students. Pre- and post-tests were conducted at the commencement and completion of each school year. All students demonstrated a significant improvement on their post-test scores, with ESL students displaying greater gains than the mainstream students. Additionally, students' results were meeting norm-referenced expectations for students of the same age. A hypothesised taxonomy was developed to further investigate which types of test items foundation ESL students displayed greatest gains. ESL students again outperformed the mainstream cohort on all levels of test categorisation, including questions that were linguistically and conceptually challenging for foundation students.

Purpose of the review To provide an overview of studies within the past five years examining the impact of social network factors on addictive behaviors among college students, to discuss gaps, limitations, and controversies in the field, and to summarize with a discussion of future directions and implications for interventions. Recent findings A review of 13 studies indicated that greater network exposure, centrality, reciprocated ties, and more tightly interconnected networks were associated with greater alcohol use and other addictive behaviors among college students. Summary Greater research is needed that expands beyond alcohol use to other addictive behaviors among college students. Additionally, more studies are needed that longitudinally study the impact of changes in social networks on addictive behaviors and vice versa, as well as studies examining sociocentric (whole) networks. Social network approaches offer innovative perspectives in understanding social influences on addictive behaviors and novel intervention strategies for potentially reducing addictive behaviors among college students.

2017-01-01

Analysis of social networks may be a useful tool for understanding the relationship between resilience and engagement, and this could be applied to educational methodologies, not only to improve academic performance, but also to create emotionally sustainable networks. This descriptive study was carried out on 134 university students. We collected the network structural variables, degree of resilience (CD-RISC 10), and engagement (UWES-S). The computer programs used were excel, UCINET for network analysis, and SPSS for statistical analysis. The analysis revealed results of means of 28.61 for resilience, 2.98 for absorption, 4.82 for dedication, and 3.13 for vigour. The students had two preferred places for sharing information: the classroom and WhatsApp. The greater the value for engagement, the greater the degree of centrality in the friendship network among students who are beginning their university studies. This relationship becomes reversed as the students move to later academic years. In terms of resilience, the highest values correspond to greater centrality in the friendship networks. The variables of engagement and resilience influenced the university students’ support networks. PMID:29194361

With increasing use of digital scanning with restorative procedures in the dental office, it becomes necessary that educational institutions adopt instructional methodology for introducing this technology together with conventional impression techniques. To compare the time differences between instructing dental students on digital scanning (DS) (LAVA C.O.S. digital impression system) and a conventional impression technique (CI) (polyvinyl siloxane), and to compare students' attitudes and beliefs towards both techniques. Volunteer sophomore dental students (n = 25) with no prior experience in clinical impressions were recruited and IRB consent obtained. Participants responded to a pre-and post-exposure questionnaire. Participants were instructed on the use of both DS and CI for a single tooth full coverage crown restoration using a consecutive sequence of video lecture, investigator-led demonstration and independent impression exercise. The time necessary for each step (minutes) was recorded. Statistical significance was calculated using dependent t-tests (time measurements) and 2-sample Mann-Whitney (questionnaire responses). The time spent teaching students was greater for DS than CI for video lecture (15.95 and 10.07 min, P = 0.0000), demonstration time (9.06 and 4.70 min, P = 0.0000) and impression time (18.17 and 8.59 min, P = 0.0000). Prior to the instruction and practice, students considered themselves more familiar with CI (3.96) than DS (1.96) (P = 0.0000). After the instruction and practice, participants reported CI technique proved significantly easier than expected (pre-instruction: 3.52 and post-instruction: 4.08, P = 0.002). However, overall participants' perception of ease of use for DS was not influenced by this instruction and practice experience (pre-instruction: 3.84 and post-instruction: 3.56, P = 0.106). Despite the results, 96% of participants expressed an expectation that DS will become their predominant impression technique during their

Brice, Chad; Masia Warner, Carrie; Okazaki, Sumie; Ma, Pei-Wen Winnie; Sanchez, Amanda; Esseling, Petra; Lynch, Chelsea

2015-10-01

Asian American adults endorse more symptoms of social anxiety (SA) on self-report measures than European Americans, but demonstrate lower prevalence rates of SA disorder in epidemiological studies. These divergent results create ambiguity concerning the mental health needs of Asian Americans. The present study is the first to investigate this issue in adolescents through assessment of self-reported SA in Asian American high school students. Parent and self-ratings of impairment related to SA and self-reported mental health service use for SA were also measured. Asian American students endorsed a greater number of SA symptoms and scored in the clinical range more frequently than other ethnic groups. Also, Asian American and Latino students endorsed more school impairment related to SA than other ethnic groups. No differences in parent-reported impairment or service utilization were identified. Implications for future research and treatment for SA among Asian American adolescents are discussed.

Carolan, Mary C; Kruger, Gina B

2011-01-01

Since 2000, there has been a shift to undergraduate midwifery education in Australia. Midwifery students are generally highly motivated, however attrition rates remain high among first-year students. This study was undertaken in one Australian University against a background of high course demand and high student attrition. Thirty-two first-year midwifery students completed a demographic questionnaire and wrote a reflection in response to the question: What if anything, would make your experience as a first year student better? Data were subjected to thematic content analysis. Findings indicated a need for: greater opportunities to prepare; for more time to study; for greater student supports; and outlined difficulties such as financial and childcare. In conclusion, undergraduate midwifery courses and local conditions vary among institutions. Student feedback is a useful way of identifying local concerns that may impact on student completion rates. This is a necessary first step to the provision of meaningful student support.

The prevalence of alcohol use and dating violence are shockingly high among male college students, making this a particularly high-risk group for alcohol-related aggression. Expanding upon previous research, the current study examined the relations between three indicators of alcohol use and three types of dating violence among 204 male college students. We also examined whether hazardous drinkers reported more violence perpetration than non-hazardous drinkers. Results demonstrated that alcohol use was related to all types of aggression, and hazardous drinkers are at greater risk of violence perpetration than non-hazardous drinkers. Implications for dating violence prevention programs and future research are discussed. © The Author(s) 2014.

This trial compares the effectiveness and safety of HYC-24L (Juvéderm Ultra XC; Allergan plc, Dublin, Ireland) (24 mg/mL of hyaluronic acid, 0.3% lidocaine) and CPM-22.5 (Belotero Balance; Merz Aesthetics, Raleigh, NC) (22.5 mg/mL of hyaluronic acid) for the treatment of perioral lines. Men and women aged 35 years or older with moderate-to-severe perioral lines were recruited for this randomized controlled, rater-blinded, 2-arm trial. The primary endpoint was a comparison of rater-assessed responder rates by the validated 4-point Perioral Lines Severity Scale at Month 6; responders were those who showed a ≥1 point improvement. A secondary endpoint was subject-assessed change in perioral lines measured by the Global Assessment of Change Scale. A total of 136 subjects received treatment and 132 completed the trial (mean age: 58 ± 8 years). Total volume injected was 1.18 mL (HYC-24L) and 1.32 mL (CPM-22.5). At Month 6, a significantly greater proportion of HYC-24L subjects responded to treatment (87%) than CPM-22.5 subjects (72%) (p < .04). At all time points, HYC-24L subjects reported significantly greater improvement in their perioral lines than CPM-22.5 subjects, with the greatest difference at Month 6. No unexpected adverse events occurred. HYC-24L subjects showed a higher response rate and a greater improvement in their perioral lines than CPM-22.5 subjects for up to 6 months.

2015-05-01

Ultrasonography is a highly useful diagnostic technique that supplements traditional physical examinations. To demonstrate that students previously trained in clinical ultrasonography are capable of instructing other students in a similar manner in a short period of time ("peer mentoring"). Five medical students in their 5th year, trained in abdominal and cardiac ultrasonography by physicians with experience, instructed 24 other students in the same procedure. The training consisted of an online theoretical course and practical training lasting about 12hours, in which each student had to perform 6 basic abdominal planes and 4 basic cardiac planes on 20 healthy volunteers. Subsequently, the students underwent an objective assessment test on healthy models performed by expert physicians in clinical ultrasonography. The students managed to correctly identify 90.2% of the basic abdominal planes, except for the left coronal (spleen and left kidney) and subcostal (gallbladder) planes, with slightly lower success rates of 82.5% and 80%, respectively. Due to the greater difficulty of obtaining cardiac planes, the success rate was lower: 70.3%, in the subxiphoid, short parasternal and four chamber planes. The cardiac plane with the fewest errors in identification was the parasternal long plane (90% success). We observed no statistically significant differences between the results (teaching capacity) of the various mentors. Medical students are capable of instructing other colleagues (peer mentoring) on the basic aspects of abdominal and cardiac ultrasonography after a relatively short training period.

‘Gamma Anna’: a classroom demonstration for teaching the concepts of gamma imaging

NASA Astrophysics Data System (ADS)

Wolff, Nicola; Griffiths, Jennifer; Yerworth, Rebecca

2017-01-01

Gamma imaging is at the interface of medicine and physics and thus its teaching is important in both fields. Pedagogic literature highlights the benefits of interactive demonstrations in teaching: an increase in enjoyment and interest, as well as improvement in academic achievement. However gamma imaging uses radioactive sources, which are potentially dangerous and thus their use is tightly controlled. We have developed a demonstration which uses a localised exothermic reaction within a rag doll as an analogue of radioactivity. This can be safely used in classrooms to demonstrate the principles of gamma imaging. The tool is easy to make, cheap, robust and portable. The supplementary material in this paper gives teacher notes and a description of how to make the rag doll demonstrator. We have tested the tool using six participants, acting as ‘teachers’, who carried out the demonstration and described the doll as easy to use, and the ‘tumour’ clearly identifiable. The teaching tool was separately demonstrated to a group of 12 GCSE physics students and a group of 12 medical students. Feedback showed increased student engagement, enjoyment and understanding of gamma imaging. Previous research has shown that these benefits have an impact on learning and academic outcomes.

HIV/AIDS stigma and knowledge among predominantly middle-class high school students in New Delhi, India.

PubMed

Pramanik, Suneet; Chartier, Maggie; Koopman, Cheryl

2006-03-01

This study examined stigmatizing attitudes toward HIV/AIDS among predominantly middle-class adolescents in New Delhi high schools. This study was specifically designed to: 1) assess stigmatizing attitudes toward HIV/AIDS and sexuality; HIV/AIDS knowledge, and awareness of HIV-related health resources; and 2) examine whether HIV-related stigma and knowledge are related to one another and to gender, parents' education, and exposure to HIV/AIDS education. In four high schools in New Delhi, 186 students completed a questionnaire assessing stigmatization of HIV/AIDS, stigmatization of sexuality, knowledge of HIV/AIDS, HIV/AIDS education and resources, and demographic characteristics. Adolescents varied in how much they stigmatized persons with HIV/AIDS. They generally lacked accurate knowledge about the disease and of related health resources. However, those with greater exposure to HIV/AIDS education demonstrated significantly greater HIV/AIDS knowledge. Female adolescents demonstrated significantly less knowledge about HIV/AIDS compared with male adolescents, while the males reported significantly greater exposure to HIV/AIDS education compared with the females. These results suggest a need for greater HIV/AIDS education and awareness of health resources, especially among female adolescents. Education must directly address stigmatizing attitudes about HIV/AIDS, gaps in HIV/AIDS knowledge and awareness of HIV-related health resources.

Prototype CoolCup cryolipolysis applicator with over 40% reduced treatment time demonstrates equivalent safety and efficacy with greater patient preference.

PubMed

Kilmer, Suzanne L

2017-01-01

Cryolipolysis is a safe, effective non-surgical procedure to reduce fat. For most cryolipolysis treatments, tissue is pulled between parallel cooling plates with a treatment duration of 60 minutes. A novel contoured cup, medium-sized applicator was developed to increase tissue contact with reduced skin tension and reduced treatment time. This prototype contoured cup was investigated with a standard cryolipolysis applicator to evaluate safety, efficacy, and patient preference. A prototype CoolCup medium-sized vacuum applicator (CoolSculpting System, ZELTIQ Aesthetics) was used to treat n = 19 subjects in the flanks. Randomly assigned, one flank received standard treatment with the CoolCore applicator (-10°C for 60 minutes). The contralateral flank received treatment from the CoolCup (-11°C for 35 minutes). The clinical study primary efficacy endpoint was 70% correct identification of baseline photographs by independent physician review. Incidence of adverse device effects was monitored. Fat layer reduction was measured by ultrasound and subject surveys were administered 12 weeks post-treatment. Equivalent efficacy was demonstrated between the CoolCore standard treatment and the prototype CoolCup. Independent review from three blinded physicians found 81% correct identification of baseline photographs for the standard treatment and 79% for the CoolCup. Ultrasound measurements indicated mean fat layer reduction of 4.38 mm for the standard treatment and 4.40 mm for the CoolCup; no statistically significant difference was found when comparing treatment efficacy of the two applicators (P = 0.96). Patient questionnaires revealed 85% preferred CoolCup because of shorter treatment duration and greater comfort. Procedural assessments revealed 45% lower pain scores for CoolCup. Immediate post-treatment clinical assessments revealed 82% less bruising. Typical side effects, such as numbness and erythema, were similar. There were no adverse events. This clinical

There has been growing recognition that medical students, interns, residents and practicing physicians across many specialties are prone to burnout, with recent studies linking high rates of burnout to adverse mental health issues. Little is known about the trajectory and origins of burnout or whether its roots may be traced to earlier in medical training, specifically, during undergraduate studies. Here, the authors surveyed undergraduates at UC San Diego (UCSD) to assess the relationship of burnout to premedical status while controlling for depression severity. Undergraduate students at UCSD were invited to participate in a web-based survey, consisting of demographic questions; the Maslach Burnout Inventory Student Survey (MBI-SS), which gauged the three dimensions of burnout; and the nine-item Patient Health Questionnaire (PHQ-9), to assess depression severity. A total of 618 premedical students and 1,441 non-premedical students completed the questionnaire. Premedical students had greater depression severity and emotional exhaustion than non-premedical students, but they also exhibited a greater sense of personal efficacy. The burnout differences were persistent even after adjusting for depression. Also, premedical women and Hispanic students had especially high levels of burnout, although differences between groups became nonsignificant after accounting for depression. Despite the limitations of using a burnout questionnaire not specifically normed for undergraduates, the unique ethnic characteristics of the sample, and the uncertain response rate, the findings highlight the importance of recognizing the unique strains and mental health disturbances that may be more common among premedical students than non-premedical students. Results also underscore the close relationship between depression and burnout, and point the way for subsequent longitudinal, multi-institutional studies that could help identify opportunities for prevention and intervention.

Dental schools are developing new curricula, with outreach placements enhancing the hospital-based training. To assess the students' experience of outreach as one component of determining the value and feasibility of outreach placements. Six-week block placements for 10 undergraduates and 3 weeks for 11 hygiene and hygiene and therapy students in existing primary care clinics, in areas of need, to work supervised by local dentists. Semi-structured interviews with 20 students by staff independent of the course team. Interviews were audio-recorded, transcribed and content analysed before being verified by a second observer. Findings were triangulated against a peer-run focus group and students' clinical records. Students were very positive about their experience and the potential role of outreach training in dental education. They described: gaining greater experience of new types of patients and their communities; learning from broader clinical experience, alternative approaches and practicing or observing dentistry in different settings; the benefits of team working; and, acquiring a more holistic and pragmatic view of health care. Many students reported gaining greater confidence, wider awareness of potential careers in dentistry and a greater sense of realism in their experience. Some reflected on their own training needs. Students also discussed the importance of preparation for the placements and the merits of different styles of supervision. Dental outreach training can provide students with valuable learning experience in a range of areas. It requires careful management to ensure those experiences match individuals' needs and the programme's purposes.

Voice Range Profiles of Singing Students: The Effects of Training Duration and Institution.

Lycke, Hugo; Siupsinskiene, Nora

2016-01-01

The aim of the study was to assess differences in voice parameters measured by the physiological voice range profile (VRP) in groups of vocally healthy subjects differentiated by the duration of vocal training and the training institution. Six basic frequency- and intensity-related VRP parameters and the frequency dip of the register transition zone were determined from VRP recordings of 162 females studying in individual singing lessons (1st-5th level) in Dutch, Belgian, English, and French public or private training facilities. Sixty-seven nonsinging female students served as controls. Singing students in more advanced singing classes demonstrated a significantly greater frequency range, particularly at high frequencies, than did first-year students. Students with private training showed a significantly increased mean intensity range in comparison to those in group classes, while students with musical theater training exhibited significantly increased frequency- and intensity-related VRP parameters in comparison to the students with classical training. When compared to nonsingers, all singing student subgroups showed significant increases in all basic VRP parameters. However, the register transition parameter was not influenced by training duration or institution. Our study suggests that the extension of physiological vocal limits might depend on training duration and institution. © 2016 S. Karger AG, Basel.

"Over my dead body?": the influence of demographics on students' willingness to participate in peer physical examination.

PubMed

Rees, Charlotte E; Bradley, Paul; Collett, Tracey; McLachlan, John C

2005-11-01

This study aims to explore quantitatively and qualitatively students' attitudes towards peer physical examination (PPE) and the influence of demographics on students' willingness to participate in PPE. A total of 296 first-year medical students from two consecutive cohorts at the Peninsula Medical School, UK completed the EFS questionnaire. Quantitative data from the questionnaire were analysed using univariate (i.e. Mann-Whitney and chi-squared tests) and multivariate statistics (i.e. stepwise multiple regression) and qualitative data were analysed using theme analysis. At least 92% of Peninsula Medical School students were willing to examine all 11 body parts (except breast and inguinal regions) of peers of same and opposite gender. Qualitative data support this by highlighting students' positive attitudes towards PPE. PPE was more acceptable within rather than across gender and students generally felt more comfortable examining their peers than being examined by peers. Qualitative data outline the range of student concerns with PPE. Significant relationships existed between students' attitudes towards PPE and various variables: gender, age and religious faith. The findings demonstrate that students may show a greater willingness to participate in PPE than previously thought. Further research is required to explore more fully the barriers to PPE.

The article contains description of several demonstration experiments connected with application of light scattering (LS) for investigation of optical properties of nanoparticles solutions. The demonstrations are based on the usage of laser pointers with different wavelengths (405, 532, and 650 nm) for observing of light scattering and absorbance by various nanoparticles (silver, gold, sulfur, and cadmium selenide). These experiments were used during short course for secondary school students ("Introduction to Nanotechnology") and applied as hands-on activities in order to introduce students to methods of investigation of nanostructures. The demonstrations (included to the course) were tested during summer-camp school (in 2015 and 2016) and in club in chemistry (2016) for secondary school students (15-17 years old).

Chiu, Ming Ming; Pong, Suet-ling; Mori, Izumi; Chow, Bonnie Wing-Yin

2014-01-01

Central to student learning and academic success, the school engagement of immigrant children also reflects their adaptation to a primary institution in their new country. Analysis of questionnaire responses of 276,165 fifteen-year-olds (50 % female) and their 10,789 school principals in 41 countries showed that school engagement has distinct, weakly-linked cognitive and emotional components. Native students had weaker attitudes toward school (cognitive engagement) but greater sense of belonging at school (emotional engagement) than immigrant students or students who spoke a foreign language at home. Students with better teacher–student relationships, teacher support or a classroom disciplinary climate often had a greater sense of belonging at school and had better attitudes toward school than other students. While immigrant students often have solid attitudes toward school, teachers can help them feel a greater sense of belonging at school. PMID:22484548

"An adjective is a word hanging down from a noun": learning to write and students with learning disabilities.

PubMed

Harris, Karen R; Graham, Steve

2013-04-01

By the upper elementary grades, writing becomes an essential tool both for learning and for showing what you know. Students who struggle significantly with writing are at a terrible disadvantage. Data from the National Assessment of Educational Progress indicate that only 25% of students can be classified as competent writers; students with learning disabilities (LD) have even greater problems with writing than their normally achieving peers and frequently demonstrate a deteriorating attitude toward writing after the primary grades. In this article, we focus on composing and the writing process, and examine the knowledge base about writing development and instruction among students with LD. We address what research tells us about skilled writers and the development of writing knowledge, strategies, skill, and the will to write, and how this relates to students with LD. Next, we summarize what has been learned from research on writing development, effective instruction, and the writing abilities of students with LD in terms of effective instruction for these students. Finally, we indicate critical areas for future research.

Whitney, Eli M; Aleksejuniene, Jolanta; Walton, Joanne N

2016-08-01

Critical thinking is a key element of complex problem-solving and professional behavior. An ideal critical thinking measurement instrument would be able to accurately predict which dental students are predisposed to and capable of thinking critically and applying such thinking skills to clinical situations. The aims of this study were to describe critical thinking disposition and skills in dental students at the beginning and end of their first year, examine cohort and gender effects, and compare their critical thinking test scores to their first-year grades. Volunteers from three student cohorts at the University of British Columbia were tested using the California Critical Thinking Disposition Inventory and California Critical Thinking Skills instruments at the beginning and end of their first year. Based on the preliminary findings, one cohort was retested at graduation when their final-year grades and clinical advisor rankings were compared to their critical thinking test scores. The results showed that students who entered dental school with higher critical thinking scores tended to complete their first year with higher critical thinking scores, achieve higher grades, and show greater disposition to think critically at the start of the program. Students who demonstrated an ability to think critically and had a disposition to do so at the start of the program were also likely to demonstrate those same attributes at the completion of their training. High critical thinking scores were associated with success in both didactic and clinical settings in dental school.

Sleep quality not only refers to sleeping well at night, but also includes appropriate daytime functioning. Poor quality of sleep can affect a variety of attention processes. The aim of this investigation was to evaluate the relationship between the perceived quality of sleep and selective focus in a group of college students. A descriptive cross-sectional study was carried out in a group of 52 Argentinian college students of the Universidad Adventista del Plata. The Pittsburgh Sleep Quality Index, the Continuous Performance Test and the Trail Making Test were applied. The main results indicate that students sleep an average of 6.48 hours. Generally half of the population tested had a good quality of sleep. However, the dispersion seen in some components demonstrates the heterogeneity of the sample in these variables. It was observed that the evaluated attention processes yielded different levels of alteration in the total sample: major variability in the process of process and in the divided-attention processes were detected. A lower percentage of alteration was observed in the process of attention support. Poor quality of sleep has more impact in the sub processes with greater participation of corticocortical circuits (selective and divided attention) and greater involvement of the prefrontal cortex. Fewer difficulties were found in the attention-support processes that rely on subcortical regions and have less frontal involvement.

Shakerin, Said

2018-04-01

Demonstrations of physics phenomena via relatively simple devices and toys have been around for a long time. Because of the pedagogical value of demonstrations, this journal and other periodicals have published papers on the subject of classroom demonstrations including those related to fluid mechanics. Four new, low-cost apparatuses that demonstrate a variety of fluid mechanics phenomena are presented in this paper. The apparatuses are self-contained, instantly set up, require no electric power for operation, and are maintenance free. They can be used as demonstration tools to enhance classroom lectures and outreach activities. Alternatively, these apparatuses can be assigned as projects for students to construct and test. Further involvement, from an aesthetic point of view, might be to construct variations of them as decorative objects by collaborating with students/teachers in visual arts. Features of the apparatuses are presented first, followed by notes on fabrication to enable interested readers to replicate them.

2017-09-01

Understanding obsessive-compulsive behavior in medical students and law students is necessary for administrators and educators to properly work with students struggling with obsessionality. We aim to compare the differences in obsessive symptoms between medical students, law students and a control population. A total of 100 third-year medical students, 102 third-year law students and 103 control subjects drawn from the general population completed the Leyton Obsessional Inventory (LOI). Subjects were examined on all three sections (symptoms/traits, resistance and interference) of the LOI. Obsessional symptom scores for medical students (14.29 ± 7.33) and law students (13.65 ± 6.61) were significantly greater than for the control group (11.58 ± 7.45). Medical and law students were both more likely to report checking, order, routine and attention to detail as obsessive symptoms. Medical students were more likely than law students to possess the obsessive symptoms of cleanliness and conscientiousness, while law students were more likely than medical students to possess obsessive symptoms related to difficulty in making up their mind and doubting themselves. While medical students and law students are more obsessional than the control population, each group is more likely to report different obsessive symptoms.

Correlating Student Knowledge and Confidence Using a Graded Knowledge Survey to Assess Student Learning in a General Microbiology Classroom †

PubMed Central

Favazzo, Lacey; Willford, John D.; Watson, Rachel M.

2014-01-01

Knowledge surveys are a type of confidence survey in which students rate their confidence in their ability to answer questions rather than answering the questions. These surveys have been discussed as a tool to evaluate student in-class or curriculum-wide learning. However, disagreement exists as to whether confidence is actually an accurate measure of knowledge. With the concomitant goals of assessing content-based learning objectives and addressing this disagreement, we present herein a pretest/posttest knowledge survey study that demonstrates a significant difference correctness on graded test questions at different levels of reported confidence in a multi-semester timeframe. Questions were organized into Bloom’s taxonomy, allowing for the data collected to further provide statistical analyses on strengths and deficits in various levels of Bloom’s reasoning with regard to mean correctness. Collectively, students showed increasing confidence and correctness in all levels of thought but struggled with synthesis-level questions. However, when students were only asked to rate confidence and not answer the accompanying test questions, they reported significantly higher confidence than the control group which was asked to do both. This indicates that when students do not attempt to answer questions, they have significantly greater confidence in their ability to answer those questions. Additionally, when students rate only confidence without answering the question, resolution across Bloom’s levels of reasoning is lost. Based upon our findings, knowledge surveys can be an effective tool for assessment of both breadth and depth of knowledge, but may require students to answer questions in addition to rating confidence to provide the most accurate data.

Interprofessional education (IPE) provides students with opportunities to learn about the roles and responsibilities of other professions and develop communication and teamwork skills. As different health professions have recognised the importance of IPE, the number of disciplines participating in IPE events is increasing. Consequently, it is important to examine the effect group structure has on the learning environment and student knowledge acquisition during IPE events. The purpose of this study was to determine the effect of group composition on student perceptions of interprofessional teamwork and collaboration when participating in a case-based IPE forum. To examine this construct, six cohorts of students were divided into two groups: Group-one (2010-2012) included students from five professions. Group-two (2013-2015) included students from 10 professions. The only other change for group-two was broadening the case scenarios to ensure a role for each profession. At the conclusion of the case-based IPE forums, both groups demonstrated a statistically significant increase in 'readiness for interprofessional learning' and 'interdisciplinary education perceptions'. However, participants in group-one (2010-2012) demonstrated a greater change in scores when compared to group-two (2013-2015). It was concluded a case-based IPE forum with students from numerous health professions participating in a discussion about broad case scenarios was moderately effective at introducing students to other health professions and increasing their knowledge of others' identities. However, a smaller grouping of professions with targeted cases was more effective at influencing student perceptions of the need for teamwork. When planning an IPE event, faculty should focus on intentional groupings of professions to reflect the social context of healthcare teams so all students can fully participate and experience shared learning.

2014-01-01

Purpose. Whistleblowing is the reporting of illegal, immoral, or illegitimate practices to persons or organizations that may affect the action. The current study compares experienced nurses to nursing students regarding their willingness to blow the whistle to protect a patient's interests. Methods. 165 participants were divided into two groups: 82 undergraduate nursing students and 83 experienced nurses. Participants responded to two vignettes that described a colleague's and a manager's misconduct at work. Results. The nursing students perceived the severity of the misconduct significantly lower compared to the experienced nurses. The nursing students also ranked the internal and external whistleblowing indices higher than the nurses, but the differences did not reach statistical significance. For each of the examined internal and external indices, professional experience was found to be significant in multivariate regression analyses. Conclusions. Even though nursing students perceived the severity of the misconduct significantly lower than the experienced nurses, the students demonstrated a greater readiness to blow the whistle, both internally and externally. Recommendations for handling comparable situations are offered. PMID:25379527

2004-06-01

This analogue study compared the effectiveness of computer-generated visual displays, classroom demonstration, and traditional lecture as methods of instruction used to teach neuronal structure and processes. Randomly assigned 116 undergraduate students participated in 1 of 3 classrooms in which they experienced the same content but different teaching approaches presented by 3 different student-instructors. Then participants completed a survey of their subjective reactions and a measure of factual information designed to evaluate objective learning outcomes. Participants repeated this factual measure 5 wk. later. Results call into question the use of classroom demonstration methods as well as the trend towards devaluing traditional lecture in favor of computer-generated visual display.

NASA Astrophysics Data System (ADS)

Aurnou, J.

2005-12-01

The complex relationship between rotation and its effect on fluid motions presents some of the most difficult and vexing concepts for both undergraduate and graduate level students to learn. We have found that student comprehension is greatly increased by the presentation of in-class fluid mechanics experiments. A relatively inexpensive experimental set-up consists of the following components: a record player, a wireless camera placed in the rotating frame, a tank of fluid, and food coloring. At my poster, I will use this set-up to carry out demonstrations that illustrate the Taylor-Proudman theorem, flow within the Ekman layer, columnar convection, and flow around high and low pressure centers. By sending the output of the wireless camera through an LCD projection system, such demonstrations can be carried out even for classes in large lecture halls.

Brice, Chad; Warner, Carrie Masia; Okazaki, Sumie; Ma, Pei-Wen Winnie; Sanchez, Amanda; Esseling, Petra; Lynch, Chelsea

2014-01-01

Asian American adults endorse more symptoms of social anxiety (SA) on self-report measures than European Americans, but demonstrate lower prevalence rates of social anxiety disorder in epidemiological studies. These divergent results create ambiguity concerning the mental health needs of Asian Americans. The present study is the first to investigate this issue in adolescents through assessment of self-reported SA in Asian American high school students. Parent and self-ratings of impairment related to SA and self-reported mental health service use for SA were also measured. Asian American students endorsed a greater number of SA symptoms and scored in the clinical range more frequently than other ethnic groups. Also, Asian American and Latino students endorsed more school impairment related to SA than other ethnic groups. No differences in parent-reported impairment or service utilization were identified. Implications for future research and treatment for SA among Asian American adolescents are discussed. PMID:25300193

Part-Time Work and Physical Activity in American High School Students.

2015-08-01

To compare physical activity (PA) in American high school students who work part-time with those who do not work. Data were obtained from the National Health and Nutrition Examination Survey 2003 to 2006 (n = 791). Work status was self-reported and PA was measured using accelerometers. In males, adjusted for age, race, and poverty-income ratio, workers averaged greater counts per minute, less sedentary time, and greater moderate-to-vigorous PA compared with nonworkers. In females, workers and nonworkers had similar counts per minute, whereas nonworkers had somewhat greater moderate-to-vigorous PA. There was a work-by-school status interaction on sedentary time (P = 0.021), whereby work was associated with less sedentary time among students not on break from school. In American high school students, work is associated with greater PA in males and a different composition of PA in females.

Objective. To describe the extent to which pharmacy students hold negative attitudes toward people living with HIV/AIDS (PLWHA) and to determine whether background variables, student knowledge, and professional attitudes may affect willingness to care for PLWHA. Methods. An online survey tool was developed and administered to 150 pharmacy students in their third professional year. Descriptive and stepwise multivariate regressions were performed. Results. While descriptive results showed a majority of respondents had favorable professional attitudes towards caring for PLWHA, most pharmacy students expressed discomfort with specific attitudes about being in close physical contact and receiving selected services from PLWHA. Multivariate results revealed that: (1) being a minority predicted greater knowledge; (2) having received prior HIV instruction and greater HIV knowledge predicted more positive professional attitudes caring for PLWHA; (3) being more socially liberal, having more positive professional attitudes caring for PLWHA, and having greater empathy towards PLWHA predicted student willingness to provide services. Conclusion. Future educational interventions specifically targeted toward socially conservative whites may impact greater student willingness to care for PLWHA. Additional research should also explore the generalizability of the present findings and modeling to pharmacy students in other regions of the country. PMID:27170816

2018-05-18

Despite the paucity of supporting data, it has generally been held that proptosis in thyroid eye disease (TED) may provide relative protection from compressive optic neuropathy (CON) by producing spontaneous decompression. The objective of this study was to investigate this phenomenon in patients with bilateral TED-CON. We retrospectively reviewed the charts of 67 patients (134 orbits) with bilateral TED-CON at Columbia-Presbyterian Medical Center. Significant asymmetric proptosis (Hertel) was defined as ≥ 2 mm. Significant asymmetric CON was defined first, as the presence of an relative afferent pupillary defect. Those without an relative afferent pupillary defect were evaluated according to the TED-CON formula y = -0.69 - 0.31 × (motility) - 0.2 × (mean deviation) - 0.02 × (color vision) as previously established for the diagnosis of TED-CON. A difference in the formula result ≥ 1.0 between eyes was considered significant. Patients were then divided into 4 groups. Forty-one of 67 patients demonstrated asymmetric CON (29 by relative afferent pupillary defect, 12 by formula). Twenty-one of 67 patients demonstrated asymmetric proptosis. Only 5 of 12 (41.6%) of the patients who had both asymmetric proptosis and asymmetric CON (group 1) showed greater proptosis in the eye with less CON. Twenty-nine patients (group 2) showed that asymmetric CON occurred despite symmetrical proptosis. Seventeen patients (group 3), showed the inverse, that asymmetric differences in proptosis occurred with symmetrical CON. Despite commonly held assumptions, our results suggest that greater proptosis is not associated with improved TED-CON. Combining groups 1 to 3-all of which demonstrated asymmetry of either proptosis, CON, or both-91.4% of patients did not show a relationship between greater proptosis and improved CON.

graphs, and as raw, downloadable data. Finally, URSSA has high content validity based on its research grounding and rigorous development. We will present examples of how URSSA has been used in evaluations of UR programs. A multi-year evaluation of a university-based UR program shows that URSSA items are sensitive to differences in students' prior level of experience with research. For example, experienced student researchers reported greater gains than did their peers new to UR in understanding the process of research and in coming to see themselves as scientists. These differences are consistent with interview data that suggest a developmental progression of gains as students pursue research and gain confidence in their ability to contribute meaningfully. A second example comes from a multi-site evaluation of sites funded by the National Science Foundation's Research Experience for Undergraduates (REU) program in Biology. This study acquired data from nearly 800 students at some 60 Bio REU sites in 2010 and 2011. Results reveal differences in gains among demographic groups, and the general strength of these well-planned programs relative to a comparison sample of UR programs that are not part of REU. Our presentation will demonstrate the evaluative use of URSSA and its potential applications to undergraduate research in the geosciences.

Medical and psychology students' knowledge of and attitudes towards mindfulness as a clinical intervention.

PubMed

McKenzie, Stephen P; Hassed, Craig S; Gear, Jacqui L

2012-01-01

Mindfulness is a technique for training people to pay full attention and to fully accept the reality of what they are paying attention to. The clinical efficacy of mindfulness has been increasingly demonstrated during the last two decades. Very little research, however, has been undertaken on health professionals' and students of health professions' knowledge of and attitudes towards mindfulness. These may affect the current and future level of use of a technique that offers important clinical advantages. We aimed to compare knowledge of and attitudes towards mindfulness of medical students without exposure to it in their training with psychology students without exposure and with medical students with exposure to mindfulness in their training. A total of 91 medical students from Monash University, 49 medical students from Deakin University, and 31 psychology students from Deakin University were given a questionnaire that elicited quantitative and qualitative responses about level of knowledge of mindfulness and willingness to administer or recommend it to their future patients. Psychology students without exposure to mindfulness in their training have a greater knowledge of it and are more likely to administer it or recommend it than are medical students without exposure to it in their training. Medical students with exposure to mindfulness in their course have a greater knowledge of it and are more likely to administer it or recommend it than are medical students without exposure. Knowledge of mindfulness is positively correlated with students' willingness to use or recommend it. Possible implications of the findings of this study are that if future doctors are routinely instructed in mindfulness as a clinical intervention they may be more likely to form a more positive attitude towards it, that is more consistent with that of nonmedical health professions such as psychologists, and that they therefore may be more likely to administer it or refer its use.

The city has proved to be the most successful form of human agglomeration and provides wide employment opportunities for its dwellers. As advances in robotics and artificial intelligence revive concerns about the impact of automation on jobs, a question looms: how will automation affect employment in cities? Here, we provide a comparative picture of the impact of automation across US urban areas. Small cities will undertake greater adjustments, such as worker displacement and job content substitutions. We demonstrate that large cities exhibit increased occupational and skill specialization due to increased abundance of managerial and technical professions. These occupations are not easily automatable, and, thus, reduce the potential impact of automation in large cities. Our results pass several robustness checks including potential errors in the estimation of occupational automation and subsampling of occupations. Our study provides the first empirical law connecting two societal forces: urban agglomeration and automation's impact on employment. © 2018 The Authors.

These findings inform best practices associated with environmental education. The implications include teacher-practitioner collaboration with IT personnel, naturalists, hydrologists, zoological and botanical experts, to design local, site-based virtual-nature and in-nature (or hybrid) field trips to nurture environmental literacy goals.

The Downside of Greater Lexical Influences: Selectively Poorer Speech Perception in Noise

PubMed Central

Xie, Zilong; Tessmer, Rachel; Chandrasekaran, Bharath

2017-01-01

Purpose Although lexical information influences phoneme perception, the extent to which reliance on lexical information enhances speech processing in challenging listening environments is unclear. We examined the extent to which individual differences in lexical influences on phonemic processing impact speech processing in maskers containing varying degrees of linguistic information (2-talker babble or pink noise). Method Twenty-nine monolingual English speakers were instructed to ignore the lexical status of spoken syllables (e.g., gift vs. kift) and to only categorize the initial phonemes (/g/ vs. /k/). The same participants then performed speech recognition tasks in the presence of 2-talker babble or pink noise in audio-only and audiovisual conditions. Results Individuals who demonstrated greater lexical influences on phonemic processing experienced greater speech processing difficulties in 2-talker babble than in pink noise. These selective difficulties were present across audio-only and audiovisual conditions. Conclusion Individuals with greater reliance on lexical processes during speech perception exhibit impaired speech recognition in listening conditions in which competing talkers introduce audible linguistic interferences. Future studies should examine the locus of lexical influences/interferences on phonemic processing and speech-in-speech processing. PMID:28586824

Demonstration and evaluation of gas turbine transit buses

1983-01-01

The Gas Turbine Transit Bus Demonstration Program was designed to demonstrate and evaluate the operation of gas turbine engines in transit coaches in revenue service compared with diesel powered coaches. The main objective of the program was to accelerate development and commercialization of automotive gas turbines. The benefits from the installation of this engine in a transit coach were expected to be reduced weight, cleaner exhaust emissions, lower noise levels, reduced engine vibration and maintenance requirements, improved reliability and vehicle performance, greater engine braking capability, and superior cold weather starting. Four RTS-II advanced design transit coaches were converted to gas turbine power using engines and transmissions. Development, acceptance, performance and systems tests were performed on the coaches prior to the revenue service demonstration.

Dating violence and posttraumatic stress disorder symptoms in Taiwanese college students: the roles of cultural beliefs.

PubMed

Shen, April Chiung-Tao

2014-03-01

This study has examined the effects that young adults' experience of dating-violence victimization can have on their manifestation of posttraumatic stress disorder (PTSD) symptoms. This study has also examined the possible roles that cultural beliefs can play in dating-violence experience, coping choices, and PTSD symptoms. This study has used self-reporting measures to collect data from a nationally stratified random sample of 1,018 college students in Taiwan. Results demonstrate that college students who had experienced dating-violence victimization reported higher levels of PTSD symptoms than those who had not. The results reveal that psychological-violence victimization and cultural beliefs have direct and indirect effects on PTSD symptoms via the mediation of young adults' use of emotion-focused coping strategies. Greater frequencies of psychological-violence victimization were associated with a greater use of emotion-focused coping, which was in turn associated with increases in PTSD symptoms. This study illustrates that traditional Chinese beliefs have played significant roles in exacerbating the risk for dating violence and PTSD, and in shaping victims' coping choices with dating violence.

For the past two years, Cal Poly's rocket program has been aggressively exploring the concept of remotely controlled, fixed wing, flyable rocket boosters. This program, embodied by a group of student engineers known as Cal Poly Space Systems, has successfully demonstrated the idea of a rocket design that incorporates a vertical launch pattern followed by a horizontal return flight and landing. Though the design is meant for supersonic flight, CPSS demonstrators are deployed at a subsonic speed. Many steps have been taken by the club that allowed the evolution of the StarBooster prototype to reach its current size: a ten-foot tall, one-foot diameter, composite material rocket. Progress is currently being made that involves multiple boosters along with a second stage, third rocket.

Virtual and concrete manipulatives: a comparison of approaches for solving mathematics problems for students with autism spectrum disorder.

PubMed

Bouck, Emily C; Satsangi, Rajiv; Doughty, Teresa Taber; Courtney, William T

2014-01-01

Students with autism spectrum disorder (ASD) are included in general education classes and expected to participate in general education content, such as mathematics. Yet, little research explores academically-based mathematics instruction for this population. This single subject alternating treatment design study explored the effectiveness of concrete (physical objects that can be manipulated) and virtual (3-D objects from the Internet that can be manipulated) manipulatives to teach single- and double-digit subtraction skills. Participants in this study included three elementary-aged students (ages ranging from 6 to 10) diagnosed with ASD. Students were selected from a clinic-based setting, where all participants received medically necessary intensive services provided via one-to-one, trained therapists. Both forms of manipulatives successfully assisted students in accurately and independently solving subtraction problem. However, all three students demonstrated greater accuracy and faster independence with the virtual manipulatives as compared to the concrete manipulatives. Beyond correctly solving the subtraction problems, students were also able to generalize their learning of subtraction through concrete and virtual manipulatives to more real-world applications.

Deaf students and their classroom communication: an evaluation of higher order categorical interactions among school and background characteristics.

PubMed

Allen, Thomas E; Anderson, Melissa L

2010-01-01

This article investigated to what extent age, use of a cochlear implant, parental hearing status, and use of sign in the home determine language of instruction for profoundly deaf children. Categorical data from 8,325 profoundly deaf students from the 2008 Annual Survey of Deaf and Hard-of-Hearing Children and Youth were analyzed using chi-square automated interaction detector, a stepwise analytic procedure that allows the assessment of higher order interactions among categorical variables. Results indicated that all characteristics were significantly related to classroom communication modality. Although younger and older students demonstrated a different distribution of communication modality, for both younger and older students, cochlear implantation had the greatest effect on differentiating students into communication modalities, yielding greater gains in the speech-only category for implanted students. For all subgroups defined by age and implantation status, the use of sign at home further segregated the sample into communication modality subgroups, reducing the likelihood of speech only and increasing the placement of students into signing classroom settings. Implications for future research in the field of deaf education are discussed.

A study on the impact of the GLOBE program on students' attitudes regarding environmental issues

NASA Astrophysics Data System (ADS)

Manfready, Gary Martin

A key objective in environmental curricula should be to instill responsible and concerned attitudes toward environmental issues. This can be accomplished through the application of innovative programs which emphasize the development of the affective domain of learning. The development of personal attitudes is one form of evidence that the affective domain is being addressed. This study was undertaken to determine the impact of the GLOBE program (Global Learning and Observation to Benefit the Environment) on the attitudes of students toward environmental issues. Three hundred and five middle and high school level students from four states were surveyed to determine their attitudes toward selected environmental statements. Results demonstrated that attitudes toward environmental issues of GLOBE students were significantly greater than non-GLOBE students. Additional analysis demonstrated that regardless of grade levels, gender, racial and ethnicity backgrounds, depth of GLOBE involvement, and degree of teachers' GLOBE experiences, GLOBE students display similar levels of attitudes toward environmental issues. Establishment of a reliable Likert scale measurement instrument was accomplished. Permission to use an existing survey was obtained. Additional items were added to increase validity. Establishment of reliability was accomplished through a Guttman split half analysis of the piloted instrument. Through the use of factor analysis, four categories or sub-groupings of attitudes were determined to exist. Reliability was established for the factors. These sub-groupings were identified as personal commitment to environmental protection, awareness of avenues for action, loci of control, and students' perception of teachers' abilities to present environmental topics. These categories were a part of the analysis of four hypotheses.

Finding science is fun in a 'Magic Show of Light' from Optical Demonstrations on an Overhead Projector for elementary school students

Lones, Joe J.; Maltseva, Nadezhda K.; Peterson, Kurt N.

2007-09-01

We seek methods of stimulating young school children to develop an interest in science and engineering through a natural curiosity for the reaction of light. Science learning now begins fully at middle school. Reading skills develop with activity at home and progress through the elementary school curriculum, and in a like manner, a curious interest in science also should begin at that stage of life. Within the ranks of educators, knowledge of optical science needs to be presented to elementary school students in an entertaining manner. One such program used by the authors is Doug Goodman's Optics Demonstrations With the Overhead Projector, co-published by and available from OSA (Optical Society of America) and SPIE-The International Society of Optical Engineering. These demonstrations have been presented in middle and high schools; however, as a special approach, the authors have developed selected Goodman demonstrations as a "Magic Show of Light" for elementary schools. Teachers in the U.S. are overloaded with classroom instruction specifically targeted at improving reading and math scores on the Standard Achievement Test (SAT); therefore, science is getting "short changed" in the education system. For the sake of our future, industry volunteers must come forward to promote interest in science beginning with K-6.

Balta, Nuri; Çetin, Ali

2017-05-01

This study is aimed at first introducing a well-known discrepant event; inseparable phone books and second, turning it into an experiment for high school or middle school students. This discrepant event could be used especially to indicate how friction force can be effective in producing an unexpected result. Demonstration, discussion, explanation and experiment steps are presented on how to turn a simple discrepant event into an instructional activity. Results showed the relationships between number of pages and force, as well as between amounts of interleave and force. In addition to these, the mathematical equation for the total force between all interleaved pages is derived. As a conclusion, this study demonstrated that not only can phone books be used, but also ordinary books, to investigate this discrepant event. This experiment can be conducted as an example to show the agreement between theoretical and experimental results along with the confounding variables. This discrepant event can be used to create a cognitive conflict in students’ minds about the concepts of ‘force and motion’ and ‘friction force’.

2018-01-01

We describe a hands-on accurate demonstrator for cosmic rays realized by six high school students. The main aim is to show the relevance and the functioning of the principal parts of a cosmic ray telescope (muon detector), with the help of two large sized wooden artefacts. The first one points out how cosmic rays can be tracked in a muon telescope, while the other one shows the key avalanche process of electronic ionization that effectively allows muon detection through a photomultiplier. Incoming cosmic rays are visualized in terms of laser beams, whose 3D trajectory is highlighted by turning on LEDs on two orthogonal matrices. Instead the avalanche ionization process is demonstrated through the avalanche falling off glass marbles on an inclined plane, finally turning on a LED. A pictured poster accompanying the demonstrator is as effective in assisting cosmic ray demonstration and its detection. The success of the demonstrator has been fully proven by the general public during a science festival, in which the corresponding project won the Honorable Mention in a dedicated competition.

Gwazdauskas, F C; McGilliard, M L; Corl, B A

2014-10-01

Several factors affect the success of students in college classes. The objective of this research was to determine what factors affect success of undergraduate students in an anatomy and physiology class. Data were collected from 602 students enrolled in the Agriculture and Life Sciences (ALS) 2304 Animal Physiology and Anatomy course from 2005 through 2012. The data set included 476 females (79.1%) and 126 males (20.9%). Time to complete exams was recorded for each student. For statistical analyses, students' majors were animal and poultry sciences (APSC), agricultural sciences, biochemistry, biological sciences, dairy science, and "other," which combined all other majors. All analyses were completed using the GLIMMIX procedure of SAS (SAS Institute Inc., Cary, NC). Gender, major, matriculation year, major by year interaction, gender by year interaction, and time to complete the exam affected final course grade. The significant gender effect was manifested in the final grade percentage of 75.9 ± 0.4 for female students compared with 72.3 ± 0.6 for male students. Junior males had final course grades comparable with those of females, but sophomore and senior males had lower final course grades than other combinations. Biology majors had a final grade of 82.4 ± 0.6 and this grade was greater than all other majors. Students classified as "other" had a final score of 74.4 ± 0.8, which was greater than agricultural science majors (69.5 ± 0.9). The APSC grade (72.6 ± 0.5) was higher than the agricultural science majors. Junior students had significantly greater final grades (76.1 ± 0.5) than sophomores (73.3 ± 0.6) and seniors (72.9 ± 0.9). All biology students had greater final grades than all other majors, but biochemistry juniors had greater final course grades than APSC, agricultural science, and dairy science juniors. "Other" seniors had greater final course grades than agricultural science seniors. The regression for time to complete the exam was

School-based victimization has short- and long-term implications for the health and academic lives of sexual minority students. This analysis assessed the prevalence and relative risk of school violence and bullying among sexual minority and heterosexual high school students. Youth Risk Behavior Survey data from 10 states and 10 large urban school districts that assessed sexual identity and had weighted data in the 2009 and/or 2011 cycle were combined to create two large population-based data sets, one containing state data and one containing district data. Prevalence of physical fighting, being threatened or injured with a weapon, weapon carrying, and being bullied on school property and not going to school because of safety concerns was calculated. Associations between these behaviors and sexual identity were identified. In the state data, sexual minority male students were at greater risk for being threatened or injured with a weapon, not going to school because of safety concerns and being bullied than heterosexual male students. Sexual minority female students were at greater risk than heterosexual female students for all five behaviors. In the district data, with one exception, sexual minority male and female students were at greater risk for all five behaviors than heterosexual students. Sexual minority students still routinely experience more school victimization than their heterosexual counterparts. The implementation of comprehensive, evidence-based programs and policies has the ability to reduce school violence and bullying, especially among sexual minority students.

The study's purpose was to investigate whether differences in local sweat rates on the upper body between American football linemen (L) and backs (B) exist independently of differences in metabolic heat production. Twelve NCAA Division I American football players (6 linemen (mass = 141.6 ± 6.5 kg, body surface area (BSA) = 2.67 ± 0.08 m2) and 6 backs (mass = 88.1 ± 13.4 kg, BSA = 2.11 ± 0.19 m2)) cycled at a fixed metabolic heat production per unit BSA of 350 W·m(-2) for 60 min in a climatic chamber (t(db) [dry bulb temperature] = 32.4°C ± 1.0°C, t(wb) [wet bulb temperature] = 26.3°C ± 0.6°C, v [air velocity] = 0.9 ± 0.1 m·s(-1)). Local sweat rates on the head, arm, shoulder, lower back, and chest were measured after 10, 30, and 50 min of exercise. Core temperature, mean skin temperature, and HR were measured throughout exercise. Because metabolic heat production per unit surface area was fixed between participants, the rate of evaporation required for heat balance was similar (L = 261 ± 35 W·m(-2), B = 294 ± 30 W·m(-2), P = 0.11). However, local sweat rates on the head, arm, shoulder, and chest were all significantly greater (P < 0.05) in linemen at all time points, and end-exercise core temperature was significantly greater (P = 0.033) in linemen (38.5°C ± 0.4°C) relative to backs (38.0°C ± 0.2°C) despite a ∼25% lower heat production per unit mass. The change in mean skin temperature from rest was greater in linemen (P < 0.001) after 15, 30, 45, and 60 min, and HR was greater in linemen for the last 30 min of exercise. Football linemen sweat significantly more on the torso and head than football backs independently of any differences in metabolic heat production per unit BSA and therefore the evaporative requirements for heat balance. Despite greater sweating, linemen demonstrated significantly greater elevations in core temperature suggesting that sweating efficiency (i.e., the proportion of sweat that evaporates) was much lower in

Recent research suggests that underrepresented minority (URM) college students, and especially first-generation URMs, may lose motivation to persist if they see science careers as unable to fulfill culturally relevant career goals. In the present study, we used a mixed-methods approach to explore patterns of motivation to pursue physical and life sciences across ethnic groups of freshman college students, as moderated by generational status. Results from a longitudinal survey (N = 249) demonstrated that freshman URM students who enter with a greater belief that science can be used to help their communities identified as scientists more strongly over time, but only among first-generation college students. Analysis of the survey data were consistent with content analysis of 11 transcripts from simultaneously conducted focus groups (N = 67); together, these studies reveal important differences in motivational characteristics both across and within ethnicity across educational generation status. First-generation URM students held the strongest prosocial values for pursuing a science major (e.g., giving back to the community). URM students broadly reported additional motivation to increase the status of their family (e.g., fulfilling aspirations for a better life). These findings demonstrate the importance of culturally connected career motives and for examining intersectional identities to understand science education choices and inform efforts to broaden participation. © 2016 M.

The Teaching Games for Understanding (TGfU) and Sport Education (SE) pedagogical models share several objectives and pedagogical processes. Despite this seemingly uncanny relationship, few studies have examined the efficacy of a hybrid TGfU/SE pedagogical model, particularly how a teacher's utilization of such a model impacts on student motivation. The purpose of the current study was to investigate the effect a hybrid TGfU/SE unit, in comparison to direct instruction, on students' perceptions of various aspects of their motivation to engage in physical education (autonomous motivation, basic psychological needs, enjoyment and intention to be physically active). A crossover design was utilized, using the technique of counterbalancing. One group experienced a hybrid SE/TGfU unit first, followed by a unit of direct instruction. A second group experienced the units in the opposite order. Participants were 55 students. The intervention was conducted over a total of 16 lessons. The hybrid unit was designed according to the characteristics of SE by using seasons, roles, persistent teams, etc. Learning tasks set by the teacher during individual lessons, however, were designed according to the pedagogical principles of TGfU. Student motivation data was generated using validated questionnaires. Results showed that regardless of the order of intervention, the two groups showed significant improvements in autonomy, competence and enjoyment when they were taught using the hybrid model. Instead, in the variables autonomous motivation, relatedness and intention to be physically active there were no significant improvements in one group. These results demonstrate that it is possible to design varied learning situations in which affiliation, leadership and trust are fostered, while tasks are adapted to the characteristics of the students. All this can cause greater autonomous motivation, and consequently, perceived competence in the student, a positive image of the sport to

Dental student debt.

The aim of this investigation is to provide information about the financial status of dental students enrolled on the Bachelor of Dental Surgery degree course at the University of Birmingham. All undergraduate dental students enrolled during the academic year 1993-94 were asked to participate in the study. The pre-tested questionnaire, which was given to all students, covered personal details, expenditure levels, income, loans, overdrafts, use of government schemes ('top-up loans'), and so on. The questionnaire was completed by 115 dental students (response rate 47%). The results showed that dental students' debts increased each year throughout the course. A top-up loan (range 700 Pounds-850 Pounds) had been taken out by 36% of students. The financial status of 9% of students was severe enough to warrant their eligibility for awards from access funds. Credit cards were possessed by 52% of the surveyed students, and although only half of these owed money, 22% owed between 500 Pounds and 2000 Pounds. Personal overdrafts were held by 56% of respondents. A total of 17% of students engaged in weekly part-time employment. The average debt for final year students was 1200 Pounds. Dental students' estimates of the level of debt they were likely to incur was greater than the actual debt presently experienced by final year students. In conclusion, this preliminary study showed that most dental students incur debt during their undergraduate course and that this debt increases during the course.

In recent years mature students have been encouraged into nurse education for the valuable qualities they are known to possess, along with their ability to assist in providing a sustainable solution to the current health care crisis. Unfortunately corresponding resources and support structures have not accompanied this widening of access and mature students are expected to fit into structures that already exist, structures that were formulated with eighteen year olds in mind. This qualitative study explores the experiences of mature students in nurse education. Three discipline specific focus group interviews were used as a means of gathering data from 28 mature students. Data were analysed using thematic content analysis as described by Burnard [Burnard, P., 1991. A method of analysing interview transcripts in qualitative research. Nurse Education Today 11, 461-466]. Findings revealed that students continue to struggle with the academic component of the course. They also found it difficult to balance the home and university divide. Greater challenges were identified by female participants as they maintained their previous roles. Males on the other hand were provided with greater freedom to pursue their studies. There is a need for curricular changes to be implemented in order to provide a greater flexibility and supportive experience for mature students. Further research is advocated in this area.
