Teaching basic science to optimize transfer.

PubMed

Norman, Geoff

2009-09-01

Basic science teachers share the concern that much of what they teach is soon forgotten. Although some evidence suggests that relatively little basic science is forgotten, it may not appear so, as students commonly have difficulty using these concepts to solve or explain clinical problems: This phenomenon, using a concept learned in one context to solve a problem in a different context, is known to cognitive psychologists as transfer. The psychology literature shows that transfer is difficult; typically, even though students may know a concept, fewer than 30% will be able to use it to solve new problems. However a number of strategies to improve transfer can be adopted at the time of initial teaching of the concept, in the use of exemplars to illustrate the concept, and in practice with additional problems. In this article, we review the literature in psychology to identify practical strategies to improve transfer. Critical review of psychology literature to identify factors that enhance or impede transfer. There are a number of strategies available to teachers to facilitate transfer. These include active problem-solving at the time of initial learning, imbedding the concept in a problem context, using everyday analogies, and critically, practice with multiple dissimilar problems. Further, mixed practice, where problems illustrating different concepts are mixed together, and distributed practice, spread out over time, can result in significant and large gains. Transfer is difficult, but specific teaching strategies can enhance this skill by factors of two or three.

Metaphysics and medical education: taking holism seriously.

PubMed

Wilson, Bruce

2013-06-01

Medical education is now suffused with concepts that have their source outside the traditional scientific and medical disciplines: concepts such as holism, connectedness and reflective practice. Teaching of these, and other problematic concepts such as medical uncertainty and error, has been defined more by the challenge they pose to the standard model rather than being informed by a strong positive understanding. This challenge typically involves a critical engagement with the idea of objectivity, which is rarely acknowledged as an inherently metaphysical critique. Consequently, these ideas prove to be difficult to teach well. I suggest that the lack of an integrating, positive narrative is the reason for teaching difficulty, and propose that what is needed is an explicit commitment to teach the metaphysics of medicine, with the concept of holism being the fulcrum on which the remaining concepts turn. An acknowledged metaphysical narrative will encompass the scientific realism that medical students typically bring to their tertiary education, and at the same time enable a bigger picture to be drawn that puts the newer and more problematic concepts into context. © 2013 John Wiley & Sons Ltd.

Tapilouw, Marisa Christina; Firman, Harry; Redjeki, Sri; Chandra, Didi Teguh

2017-05-01

Teacher training is one form of continuous professional development. Before organizing teacher training (material, time frame), a survey about teacher's need has to be done. Science teacher's perception about science learning in the classroom, the most difficult learning model, difficulties of lesson plan would be a good input for teacher training program. This survey conducted in June 2016. About 23 science teacher filled in the questionnaire. The core of questions are training participation, the most difficult science subject matter, the most difficult learning model, the difficulties of making lesson plan, knowledge of integrated science and problem based learning. Mostly, experienced teacher participated training once a year. Science training is very important to enhance professional competency and to improve the way of teaching. The difficulties of subject matter depend on teacher's education background. The physics subject matter in class VIII and IX are difficult to teach for most respondent because of many formulas and abstract. Respondents found difficulties in making lesson plan, in term of choosing the right learning model for some subject matter. Based on the result, inquiry, cooperative, practice are frequently used in science class. Integrated science is understood as a mix between Biology, Physics and Chemistry concepts. On the other hand, respondents argue that problem based learning was difficult especially in finding contextual problem. All the questionnaire result can be used as an input for teacher training program in order to enhanced teacher's competency. Difficult concepts, integrated science, teaching plan, problem based learning can be shared in teacher training.

2016-01-01

Objective: To compare the perception of medical students on the usefulness of the interactive lectures, case-based lectures, and structured interactive sessions (SIS) in teaching and learning of Physiology. Methods: A cross-sectional study was carried out from January to December 2012 at Bahria University Medical & Dental College, Karachi, which had qualitative and quantitative aspects, assessed by self- reported questionnaire and focused group discussion (FGD). The questionnaire was distributed to 100 medical students after completion of first year of teaching of MBBS Physiology. The data was analyzed using SPSS version 15. Differences were considered significant at p-values <0.05 after application of Friedman test. Responses of FGD were analyzed. Results: All the teaching methodologies helped in understanding of precise learning objectives. The comprehension of structure and functions with understanding of difficult concepts was made best possible by SIS (p=0.04, p<0.01). SIS enabled adult learning, self-directed learning, peer learning and critical reasoning more than the other teaching strategies (p< 0.01). Conclusion: SIS involved students who used reasoning skills and power of discussion in a group to comprehend difficult concepts for better understanding of Physiology as compared to interactive and case-based lectures.

Technology in the teaching of neuroscience: enhanced student learning.

PubMed

Griffin, John D

2003-12-01

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

Common Origins of Diverse Misconceptions: Cognitive Principles and the Development of Biology Thinking

PubMed Central

Coley, John D.; Tanner, Kimberly D.

2012-01-01

Many ideas in the biological sciences seem especially difficult to understand, learn, and teach successfully. Our goal in this feature is to explore how these difficulties may stem not from the complexity or opacity of the concepts themselves, but from the fact that they may clash with informal, intuitive, and deeply held ways of understanding the world that have been studied for decades by psychologists. We give a brief overview of the field of developmental cognitive psychology. Then, in each of the following sections, we present a number of common challenges faced by students in the biological sciences. These may be in the form of misconceptions, biases, or simply concepts that are difficult to learn and teach, and they occur at all levels of biological analysis (molecular, cellular, organismal, population, and ecosystem). We then introduce the notion of a cognitive construal and discuss specific examples of how these cognitive principles may explain what makes some misconceptions so alluring and some biological concepts so challenging for undergraduates. We will argue that seemingly unrelated misconceptions may have common origins in a single underlying cognitive construal. These ideas emerge from our own ongoing cross-disciplinary conversation, and we think that expanding this conversation to include other biological scientists and educators, as well as other cognitive scientists, could have significant utility in improving biology teaching and learning.

A Hierarchical Biology Concept Framework: A Tool for Course Design

PubMed Central

Khodor, Julia; Halme, Dina Gould; Walker, Graham C.

2004-01-01

A typical undergraduate biology curriculum covers a very large number of concepts and details. We describe the development of a Biology Concept Framework (BCF) as a possible way to organize this material to enhance teaching and learning. Our BCF is hierarchical, places details in context, nests related concepts, and articulates concepts that are inherently obvious to experts but often difficult for novices to grasp. Our BCF is also cross-referenced, highlighting interconnections between concepts. We have found our BCF to be a versatile tool for design, evaluation, and revision of course goals and materials. There has been a call for creating Biology Concept Inventories, multiple-choice exams that test important biology concepts, analogous to those in physics, astronomy, and chemistry. We argue that the community of researchers and educators must first reach consensus about not only what concepts are important to test, but also how the concepts should be organized and how that organization might influence teaching and learning. We think that our BCF can serve as a catalyst for community-wide discussion on organizing the vast number of concepts in biology, as a model for others to formulate their own BCFs and as a contribution toward the creation of a comprehensive BCF.

Teaching genetics using hands-on models, problem solving, and inquiry-based methods

NASA Astrophysics Data System (ADS)

Hoppe, Stephanie Ann

Teaching genetics can be challenging because of the difficulty of the content and misconceptions students might hold. This thesis focused on using hands-on model activities, problem solving, and inquiry-based teaching/learning methods in order to increase student understanding in an introductory biology class in the area of genetics. Various activities using these three methods were implemented into the classes to address any misconceptions and increase student learning of the difficult concepts. The activities that were implemented were shown to be successful based on pre-post assessment score comparison. The students were assessed on the subjects of inheritance patterns, meiosis, and protein synthesis and demonstrated growth in all of the areas. It was found that hands-on models, problem solving, and inquiry-based activities were more successful in learning concepts in genetics and the students were more engaged than tradition styles of lecture.

Elucidating concepts in drug design through taste with natural and artificial sweeteners.

PubMed

Lipchock, James M; Lipchock, Sarah V

2016-11-12

Fundamental concepts in biochemistry important for drug design often lack connection to the macroscopic world and can be difficult for students to grasp, particularly those in introductory science courses at the high school and college level. Educational research has shown that multisensory teaching facilitates learning, but teaching at the high school and college level is almost exclusively limited to the visual and auditory senses. This approach neglects the lifetime of experience our students bring to the classroom in the form of taste perception and makes our teaching less supportive of those with sensory impairment. In this article, we outline a novel guided-inquiry activity that utilizes taste perception for a series of natural and artificial sweetener solutions to introduce the concepts of substrate affinity and selectivity in the context of drug design. The findings from this study demonstrate clear gains in student knowledge, as well as an increase in enthusiasm for the fields of biochemistry and drug design. © 2016 by The International Union of Biochemistry and Molecular Biology, 44(6):550-554, 2016. © 2016 The International Union of Biochemistry and Molecular Biology.

Exploring the development of novice unqualified graduate teachers' topic-specific PCK in teaching the particulate nature of matter in South Africa's classrooms

NASA Astrophysics Data System (ADS)

Pitjeng-Mosabala, Phihlo; Rollnick, Marissa

2018-05-01

This study investigates the development of Topic-Specific Pedagogical Content Knowledge (TSPCK) of 14 novice uncertified graduate science teachers during a Professional Development Intervention (PDI) on teaching particulate nature of matter. TSPCK was defined in terms of five knowledge components: learner prior knowledge, curricular saliency, representations, what is difficult to teach and conceptual teaching strategies. Data sources consisted of validated pre- and post-TSPCK and content knowledge (CK) tests, teacher-constructed Content Representations (CoRes) before and after teaching and, for four teachers, video-recorded lessons, and field notes together with teacher interviews. The purpose of this study was to investigate how the teachers develop TSPCK through the process. The results provide an insight into how initial construction of CoRes enabled the entire group to start thinking about how to teach the topic. For the four case-study teachers, evidence of TSPCK development was observed in their teaching. These teachers showed greater improvement in TSPCK and CK than those who taught only the prerequisite concepts of the topic. The findings show that it is possible for uncertified teachers to develop PCK in the practice context with appropriate PDI. Some improvement in PCK was also observed for the larger group who taught only prerequisite concepts.

Is case-based learning an effective teaching strategy to challenge students' alternative conceptions regarding chemical kinetics?

NASA Astrophysics Data System (ADS)

Yalçınkaya, Eylem; Taştan-Kırık, Özgecan; Boz, Yezdan; Yıldıran, Demet

2012-07-01

Background: Case-based learning (CBL) is simply teaching the concept to the students based on the cases. CBL involves a case, which is a scenario based on daily life, and study questions related to the case, which allows students to discuss their ideas. Chemical kinetics is one of the most difficult concepts for students in chemistry. Students have generally low levels of conceptual understanding and many alternative conceptions regarding it. Purpose: This study aimed to explore the effect of CBL on dealing with students' alternative conceptions about chemical kinetics. Sample: The sample consists of 53 high school students from one public high school in Turkey. Design and methods : Nonequivalent pre-test and post-test control group design was used. Reaction Rate Concept Test and semi-structured interviews were used for data collection. Convenience sampling technique was followed. For data analysis, the independent samples t-test and ANOVA was performed. Results : Both concept test and interview results showed that students instructed with cases had better understanding of core concepts of chemical kinetics and had less alternative conceptions related to the subject matter compared to the control group students, despite the fact that it was impossible to challenge all the alternative conceptions in the experimental group. Conclusions: CBL is an effective teaching method for challenging students' alternative conceptions in the context of chemical kinetics. Since using cases in small groups and whole class discussions has been found to be an effective way to cope with the alternative conceptions, it can be applied to other subjects and grade levels in high schools with a higher sample size. Furthermore, the effect of this method on academic achievement, motivation and critical thinking skills are other variables that can be investigated for future studies in the subject area of chemistry.

Genetic Pedagogical Content Knowledge (PCK) Ability Profile of Prospective Biology Teacher

NASA Astrophysics Data System (ADS)

Purwianingsih, W.; Muthmainnah, E.; Hidayat, T.

2017-02-01

Genetics is one of the topics or subject matter in biology that are considered difficult. Student difficulties of understanding genetics, can be caused by lack of understanding this concept and the way of teachers teach. Pedagogical Content Knowledge (PCK) is a way to understand the complex relationships between teaching and content taught through the use of specific teaching approaches. The aims of study was to analyze genetic PCK ability profile of prospective biology teacher.13 student of sixth semester Biology education department who learned Kapita Selekta Biologi SMA course, participated in this study. PCK development was measured by CoRes (Content Representation). Before students fill CoRes, students are tested mastery genetic concepts through a multiple-choice test with three tier-test. Data was obtained from the prior CoRes and its revisions, as well as the mastery concept in pre and post test. Results showed that pre-test of genetic mastery concepts average on 55.4% (low category) and beginning of the writing CoRes, student get 43.2% (Pra PCK). After students get lecture and simulating learning, the post-test increased to 63.8% (sufficient category) and PCK revision is also increase 58.1% (growing PCK). It can be concluded that mastery of subject matter could affects the ability of genetic PCK.

Twelve tips to stimulate intrinsic motivation in students through autonomy-supportive classroom teaching derived from self-determination theory.

PubMed

Kusurkar, R A; Croiset, G; Ten Cate, Th J

2011-01-01

Self-determination theory (SDT) of motivations distinguishes between intrinsic and extrinsic motivations. Intrinsic motivation is observed when one engages in an activity out of genuine interest and is truly self-determined. Intrinsic motivation is the desired type of motivation for study as it is associated with deep learning, better performance and positive well-being in comparison to extrinsic motivation. It is dependent on the fulfilment of three basic psychological needs described by SDT. These are the needs for autonomy, competence and relatedness. According to SDT, autonomy-supportive teaching is important, because it makes students feel autonomous and competent in their learning and also supported (relatedness) by their teachers. The concept of autonomy-supportive teaching is relevant to medical education, but less known. Through this article, we aim to make this concept understood and practically used by medical teachers. We used SDT literature as a basis to formulate these 12 tips. We present 12 practical tips derived from SDT, for teachers in health professions, on how to engage in autonomy-supportive teaching behaviours in order to stimulate intrinsic motivation in their students. These tips demonstrate that it is not difficult to engage in autonomy-supportive teaching behaviour. It can be learned through practice and self-reflection on teaching practices.

A novel technique for teaching the brachial plexus.

PubMed

Lefroy, Henrietta; Burdon-Bailey, Victoria; Bhangu, Aneel; Abrahams, Peter

2011-09-01

The brachial plexus has posed problems for both students and teachers throughout generations of medical education. The anatomy is intricate, and traditional pictorial representations can be difficult to understand and learn. Few innovative teaching methods have been reported. The basic anatomy of the brachial plexus is core knowledge required by medical students to aid clinical examination and diagnosis. A more detailed understanding is necessary for a variety of specialists, including surgeons, anaesthetists and radiologists. Here, we present a novel, cheap and interactive method of teaching the brachial plexus. Using coloured pipe cleaners, teachers and students can construct three-dimensional models using different colours to denote the origin and outflow of each nerve. The three-dimensional nature of the model also allows for a better understanding of certain intricacies of the plexus. Students may use these models as adjuncts for self study, didactic lectures and tutorials. Compared with traditional textbooks and whiteboards, the pipe-cleaner model was preferred by medical students, and provided a higher level of student satisfaction. This was demonstrated and analysed using student feedback forms. Our model could be incorporated into current curricula to provide an effective and enjoyable way of rapidly teaching a difficult concept. Other such novel methods for teaching complex anatomical principles should be encouraged and explored. © Blackwell Publishing Ltd 2011.

Integrating Inquiry-Based Science and Education Methods Courses in a "Science Semester" for Future Elementary Teachers

Madsen, J.; Fifield, S.; Allen, D.; Brickhouse, N.; Dagher, Z.; Ford, D.; Shipman, H.

2001-05-01

In this NSF-funded project we will adapt problem-based learning (PBL) and other inquiry-based approaches to create an integrated science and education methods curriculum ("science semester") for elementary teacher education majors. Our goal is to foster integrated understandings of science and pedagogy that future elementary teachers need to effectively use inquiry-based approaches in their classrooms. This project responds to calls to improve science education for all students by making preservice teachers' experiences in undergraduate science courses more consistent with reforms at the K-12 level. The involved faculty teach three science courses (biology, earth science, physical science) and an elementary science education methods course that are degree requirements for elementary teacher education majors. Presently, students take the courses in variable sequences and at widely scattered times. Too many students fail to appreciate the value of science courses to their future careers as teachers, and when they reach the methods course in the junior year they often retain little of the science content studied earlier. These episodic encounters with science make it difficult for students to learn the content, and to translate their understandings of science into effective, inquiry-based teaching strategies. To encourage integrated understandings of science concepts and pedagogy we will coordinate the science and methods courses in a junior-year science semester. Traditional subject matter boundaries will be crossed to stress shared themes that teachers must understand to teach standards-based elementary science. We will adapt exemplary approaches that support both learning science and learning how to teach science. Students will work collaboratively on multidisciplinary PBL activities that place science concepts in authentic contexts and build learning skills. "Lecture" meetings will be large group active learning sessions that help students understand difficult concepts, make connections between class activities, and launch and wrap-up PBL problems. Labs will include activities from elementary science kits as launching points for in-depth investigations that demonstrate the continuity of science concepts and pedagogies across age levels. In the methods course, students will critically explore the theory and practice of elementary science teaching, drawing on their shared experiences of inquiry learning in the science courses. Field placements in elementary classrooms will allow students to ground their studies of science and pedagogy in actual practice.

2013-01-01

We have designed a three-week experiment that can complement any microbiology course, to teach main geomicrobiology concepts for non-geology majors. One of the most difficult concepts for non-geology majors to comprehend is how bacteria serve as a platform for different mineralization reactions. In our three-week laboratory practice, students learn the main principles and conditions required for an induced bacterial mineralization. Upon completion of the laboratory experience, students will: 1) learn how microbial-induced mineralization (such as calcium carbonate formation) is affected by differential media and growth conditions; 2) understand how bacterial physiology affects any induced in situ or in vitro mineralization; 3) comprehend how growing conditions and bacterial physiologies interrelate, resulting in differential crystal formation. The teaching-learning process was assessed using a pre-/posttest with an increase from 26% to 76% in the number of positive answers from the students. We also measured the students' proficiency while conducting specific technical tasks, revealing no major difficulties while conducting the experiments. A final questionnaire was provided with satisfactory evaluations from the students regarding the organization and content of the practices. 84-86% of the students agreed that the exercises improved their knowledge in geomicrobiology and would like to attend similar laboratories in the future. Such response is the best indicator that the laboratory practice can be implemented in any undergraduate/graduate microbiology course to effectively teach basic geomicrobiology concepts to non-geology majors.

The complexity of teaching density in middle school

NASA Astrophysics Data System (ADS)

Hashweh, Maher Z.

2016-01-01

Background: Density is difficult to learn and teach in middle schools. This study, hypothesizing that the density concept develops as part of a conceptual system, used a conceptual change approach to teaching density. The approach emphasized the use of multiple strategies to teach the density concept and the associated concepts in the conceptual system. Purpose: This study assessed post-instructional understanding of different aspects of density in a sample of seventh grade students, examined the effectiveness of the multi-dimensional approach in teaching density, investigated the relations between prior student characteristics and their post-instructional understanding, and investigated if the concept of density develops as part of a conceptual system. Program description: In the first part of the study, student understanding of density was assessed in regular classrooms. In the second part, the investigator and a science teacher co-taught the density unit over a two-week period emphasizing relations between density, mass, volume, part-whole relations, and a scientific particulate conception of matter. A conceptual change approach was used which emphasized multiple representations of knowledge and the use of analogies. Sample: The sample in regular classes consisted of 1645 seventh graders in 51 schools in the West Bank, Palestine. The intervention group consisted of 29 students in one school. Design and methods: The post-instructional understanding of density in 51 regularly taught classrooms was assessed in the first part of the study using a pencil-and paper test. In the second part, a pre-test was used with the intervention group. Students in both parts of the study took the same post-test. Descriptive statistics were calculated to describe student performance. Comparison between pre-test and post-test performance of students in the intervention group was conducted using t-test and ANOVA. Correlations between pre-test sub-scores and post-test scores for students in the intervention class also were calculated. X2 was used to test for co-development of the density concept and other concepts using the different items of the post-test for all groups. Results: Student understanding of density was found poor after instruction, while the intervention had a moderate effect on understanding. Students who started with a basic understanding of some aspects of density gained more from the intervention. The density concept co-developed with the concept of volume and a particulate conception of matter. Conclusions: Teaching density as part of a conceptual system helps promote understanding of the concept. This requires the continuous development and refinement of a learning progression of density, volume, and the particulate nature of matter on the one hand, and an in-depth treatment while teaching the concept on the other hand.

Strategies for teaching object-oriented concepts with Java

NASA Astrophysics Data System (ADS)

Sicilia, Miguel-Ángel

2006-03-01

A considerable amount of experiences in teaching object-oriented concepts using the Java language have been reported to date, some of which describe language pitfalls and concrete learning difficulties. In this paper, a number of additional issues that have been experienced as difficult for students to master, along with approaches intended to overcome them, are addressed. Concretely, practical issues regarding associations, interfaces, genericity and exceptions are described. These issues suggest that more emphasis is required on presenting Java programs as derivations of conceptual models, in order to guarantee that a thorough design of the object structure actually precedes implementation issues. In addition, common student misunderstandings about the uses of interfaces and exceptions point to the necessity of introducing both specific design philosophies and also a clear distinction between design-for-reuse and more specific implementation issues.

Models are an important tool in science: not only do they act as a convenient device for describing a system or problem, but they also act as a conceptual tool for framing and exploring hypotheses. Models, and in particular computer simulations, are also an important education tool for training scientists, but it is difficult to teach students the…

Student’s misconceptions have been concerned over twenty years in the chemistry education research. It influences students to learn new knowledge and gain a correct concept. The buffer solution is found as a difficult topic due to student’s misconception. However, the research related this subject are still rare. Concept cartoon has been used as one of the effective tools to diagnose misconceptions. This study aims to identify the effectiveness of concept cartoon to diagnose them. The concept cartoon consists of three concept questions. 98 students of grade 11 as respondents of this research and followed by interview for selected students. The data obtain of the study are analyzed by using a scoring key. The detected misconceptions are about what buffers do, what buffers are, and how buffers are able to do what they do. Concept cartoon is potential as a basic tool for remedial teaching.

Concepts regarding momentum and energy are especially difficult for students to grasp and concrete examples are valuable. We will discuss, and show video, of launching water rockets using standard plastic soda and water bottles and describe the launcher composed of PVC pipe and a bicycle pump. We pose the question to students of the ratio of water to air that achieves the greatest time-of-flight. Immediate feedback is obtained by immediately testing student's hypotheses. After several launches the students understanding of Newton's Third Law and momentum and energy concepts improves. This is an engaging activity, students enjoy watching their instructors become thoroughly drenched, and students are enthusiastic. This enthusiasm, fun, and immediate testing of hypotheses reinforce momentum and energy concepts as will be shown by questionnaire results.

Interest in computer-based learning, especially in the use of virtual reality simulations is increasing rapidly. While there are good reasons to believe that technologies have the potential to improve teaching and learning, how to utilize the technology effectively in teaching specific content difficulties is challenging. To help students develop robust understandings of correct physics concepts, we have developed interactive virtual experiment simulations that have the unique feature of enabling students to experience force and motion via an analogue joystick, allowing them to feel the applied force and simultaneously see its effects. The simulations provide students learning experiences that integrate both scientific representations and low-level sensory cues such as haptic cues under a single setting. In this paper, we introduce a virtual experiment module on circular motion. A controlled study has been conducted to evaluate the impact of using this virtual experiment on students' learning of force and motion in the context of circular motion. The results show that the interactive virtual experiment method is preferred by students and is more effective in helping students grasp the physics concepts than the traditional education method such as problem-solving practices. Our research suggests that well-developed interactive virtual experiments can be useful tools in teaching difficult concepts in science.

Teaching Introductory Mineralogy With the GeoWall

Anderson, C. D.; Haymon, R. M.

2003-12-01

Mineralogy, like many topics in Earth Sciences, contains inherently three-dimensional topics that are difficult to teach. Concepts such as crystal symmetry and forms, Miller indices, the polymerization of silica tetrahedra and resulting structures of silicate mineral groups, and the interaction of light and minerals are particularly difficult. Two-dimensional diagrams are limited in their effectiveness, and physical models, while effective, are expensive and do not work as well in large class settings. The GeoWall system brings the effectiveness of physical models to the large classroom. In Fall 2003, we will integrate the GeoWall into our introductory mineralogy classes at UCSB using a combination of commercial software, atomic structure models available on the web, and custom content created in-house. The commercial software SHAPE (www.shapesoftware.com) allows users to build and display crystal shapes and their symmetry. Though not designed for the GeoWall, the software's stereopair display mode works perfectly on the system. Using the Chime web browser plug-in (www.mdl.com), computer models of silicate minerals available from the Virtual Museum of Minerals and Molecules (www.soils.umn.eduvirtual_museum) provide an interactive display of silicate mineral structure that illustrates the tetrahedral framework. Again, while not developed for the GeoWall, the Chime plug-in works seamlessly with the GeoWall hardware. 3-D GeoWall images that display light paths through minerals, and reveal relationships between crystal symmetry and optical indicatrix properties, have been developed in-house using a combination of SHAPE and 3D modeling software. The 3-D GeoWall images should convey in an instant these difficult concepts that students historically have struggled to visualize. Initial assessment of the GeoWall's effectiveness as a mineralogy teaching aid at UCSB in Fall 2003 will come from the instructor's impressions and by comparing test scores with classes from previous years.

Understanding concepts of molecular mechanisms of drug action involves sequential visualization of physiological processes and drug effects, a task that can be difficult at an undergraduate level. Role-play is a teaching-learning methodology whereby active participation of students as well as clear visualization of the phenomenon is used to convey complex physiological concepts. However, its use in teaching drug action, a process that demands understanding of a second level of complexity over the physiological process, has not been investigated. We hypothesized that role-play can be an effective and well accepted method for teaching molecular pharmacology. In an observational study, students were guided to perform a role-play on a selected topic involving drug activity. Students' gain in knowledge was assessed comparing validated pre- and post-test questionnaires as well as class average normalized gain. The acceptance of role-play among undergraduate medical students was evaluated by Likert scale analysis and thematic analysis of their open-ended written responses. Significant improvement in knowledge (P < 0.001) was noted in the pre- to post-test knowledge scores, while a high gain in class average normalized score was evident. In Likert scale analysis, most students (93%) expressed that role-play was an acceptable way of teaching. In a thematic analysis, themes of both strengths and weaknesses of the session emerged. Role-play can be effectively utilized while teaching selected topics of molecular pharmacology in undergraduate medical curricula.

Experiences Teaching Stoichiometry to Students in Grades 10 and 11

NASA Astrophysics Data System (ADS)

Bridges, Cynthia Denise

Many students have problems learning stoichiometry, a complex mathematical chemistry concept used to determine how much product will be produced or formed from a given quantity of reactants. The problem addressed in this study was teachers' lack of understanding of how to teach stoichiometry in a Midwestern urban school district. The conceptual framework of the study was based upon constructivist theory. A qualitative narrative approach was used to obtain the perceptions of 5 high school chemistry instructors related to their experiences, successful or unsuccessful, in teaching stoichiometry to students in Grades 10 and 11. Data were gathered through face-to-face interviews, which were analyzed via an inductive approach to reveal 6 themes: a difficult subject to teach, presentation of stoichiometry, relevancy, students' reactions, barriers, and gender differences. Findings suggested the need for teachers to be knowledgeable, creative, and resourceful in their subject areas to help their students to learn stoichiometry. Findings also revealed the need for teachers to adapt their instructional strategies and modes of delivery to reflect their students' individual learning styles. Understanding how the participating teachers explained stoichiometry to their students might help other chemistry teachers to examine and adapt their own instructional styles and delivery methods of the concept. This understanding might, in term, help to improve student achievement in stoichiometry in particular and chemistry in general.

Anatomy and physiology instructors often face the daunting task of teaching the principles of neurophysiology as part of a laboratory course with very limited resources. Teaching neurophysiology can be a difficult undertaking as sophisticated electrophysiology and data acquisition equipment is often financially out-of-reach for two-year institutions, and for many preparations, instructors need to be highly skilled in electrophysiology techniques when teaching hands-on laboratories. In the absence of appropriate laboratory tools, many undergraduate students have difficulty understanding concepts related to neurophysiology. The cricket can serve as a reliable invertebrate model to teach the basic concepts of neurophysiology in the educational laboratory. In this manuscript, we describe a series of hands-on, demonstrative, technologically simple, and affordable laboratory activities that will help undergraduate students gain an understanding of the principles of neurophysiology. By using the cerci ganglion and leg preparation, students can quantify extracellular neural activity in response to sensory stimulation, understand the principles of rate coding and somatotopy, perform electrical microstimulation to understand the threshold of sensory stimulation, and do pharmacological manipulation of neuronal activity. We describe the utility of these laboratory activities, provide a convenient protocol for quantifying extracellular recordings, and discuss feedback provided by undergraduate students with regards to the quality of the educational experience after performing the lab activities.

Fractions are well known to be difficult to learn. Various hypotheses have been proposed in order to explain those difficulties: fractions can denote different concepts; their understanding requires a conceptual reorganization with regard to natural numbers; and using fractions involves the articulation of conceptual knowledge with complex manipulation of procedures. In order to encompass the major aspects of knowledge about fractions, we propose to distinguish between conceptual and procedural knowledge. We designed a test aimed at assessing the main components of fraction knowledge. The test was carried out by fourth-, fifth- and sixth-graders from the French Community of Belgium. The results showed large differences between categories. Pupils seemed to master the part-whole concept, whereas numbers and operations posed problems. Moreover, pupils seemed to apply procedures they do not fully understand. Our results offer further directions to explain why fractions are amongst the most difficult mathematical topics in primary education. This study offers a number of recommendations on how to teach fractions.

Big Ideas in Volcanology-a new way to teach and think about the subject?

2011-12-01

As intense work with identifying and presenting earth science to middle school science teachers in the MiTEP project advances, I have realized that tools used to connect with teachers and students of earth science in general and especially to promote higher levels of learning, should be advantageous in graduate teaching as well. In my last of 40 years of teaching graduate volcanology, I have finally organized the class around ideas based on Earth Science Literacy Principles and on common misconceptions. As such, I propose and fully explore the twelve "big ideas" of volcanology at the rate of one per week. This curricular organization highlights the ideas in volcanology that have major impact beyond volcanology itself and explores the roots and global ramifications of these ideas. Together they show how volcanology interfaces with the science world and the "real" world or how volcanologists interface with "real" people. In addition to big ideas we explore difficult and misunderstood concepts and the public misconceptions associated with each. The new organization and its focus on understanding relevant and far reaching concepts and hypotheses provides a refreshing context for advanced learning. It is planned to be the basis for an interactive website.

Teaching three-dimensional surgical concepts of inguinal hernia in a time-effective manner using a two-dimensional paper-cut.

Mann, B D; Seidman, A; Haley, T; Sachdeva, A K

1997-06-01

Because inguinal hernia repair is difficult for third-year students to comprehend, a 2-dimensional paper-cut was developed to teach the concepts of inguinal hernia in a time-effective manner before students' observation of herniorrhaphy in the operating room. Using Adobe Illustrator 5.5 for MacIntosh, a 2-dimensional inexpensively printed paper-cut was created to allow students to perform their own simulated hernia repair before observing surgery. The exercise was performed using a no.15 scalpel or an iris scissors and was evaluated by comparing 10-question pre-tests and post-tests. Seventy-five students performed the exercise, most completing it within 15 minutes. The mean pre-test score was 7.4/10 and the mean post-test score was 9.1/10. Students performing the paper-cut reported better understanding when observing actual herniorrhaphy. A 2-dimensional paper-cut ("surgical origami") may be a time-effective method to prepare students for the observation of hernia repair.

Creating the Chemistry in Cellular Respiration Concept Inventory (CCRCI)

NASA Astrophysics Data System (ADS)

Forshee, Jay Lance, II

Students at our institution report cellular respiration to be the most difficult concept they encounter in undergraduate biology, but why students find this difficult is unknown. Students may find cellular respiration difficult because there is a large amount of steps, or because there are persistent, long-lasting misconceptions and misunderstandings surrounding their knowledge of chemistry, which affect their performance on cellular respiration assessments. Most studies of cellular respiration focus on student macro understanding of the process related to breathing, and matter and energy. To date, no studies identify which chemistry concepts are most relevant to students' development of an understanding of the process of cellular respiration or have developed an assessment to measure student understanding of them. Following the Delphi method, the researchers conducted expert interviews with faculty members from four-year, masters-, and PhD-granting institutions who teach undergraduate general biology, and are experts in their respective fields of biology. From these interviews, researchers identified twelve chemistry concepts important to understanding cellular respiration and using surveys, these twelve concepts were refined into five (electron transfer, energy transfer, thermodynamics (law/conservation), chemical reactions, and gradients). The researchers then interviewed undergraduate introductory biology students at a large Midwestern university to identify their knowledge and misconceptions of the chemistry concepts that the faculty had identified previously as important. The CCRCI was developed using the five important chemistry concepts underlying cellular respiration. The final version of the CCRCI was administered to n=160 introductory biology students during the spring 2017 semester. Reliability of the CCRCI was evaluated using Cronbach's alpha (=.7) and split-half reliability (=.769), and validity of the instrument was assessed through content validity via expert agreement, response process validity through student think-aloud interviews, and via the Delphi survey methodology. Included is a discussion of item function (difficulty, discrimination, and point-biserial correlation), persistent misconceptions and the interpretation, uses, and future directions of the CCRCI.

Students' Multimodal Construction of the Work-Energy Concept

Tang, Kok-Sing; Chee Tan, Seng; Yeo, Jennifer

2011-09-01

This article examines the role of multimodalities in representing the concept of work-energy by studying the collaborative discourse of a group of ninth-grade physics students engaging in an inquiry-based instruction. Theorising a scientific concept as a network of meaning relationships across semiotic modalities situated in human activity, this article analyses the students' interactions through their use of natural language, mathematical symbolism, depiction, and gestures, and examines the intertextual meanings made through the integration of these modalities. Results indicate that the thematic integration of multimodalities is both difficult and necessary for students in order to construct a scientific understanding that is congruent with the physics curriculum. More significantly, the difficulties in multimodal integration stem from the subtle differences in the categorical, quantitative, and spatial meanings of the work-energy concept whose contrasts are often not made explicit to the students. The implications of these analyses and findings for science teaching and educational research are discussed.

Teaching evolution (and all of biology) more effectively: Strategies for engagement, critical reasoning, and confronting misconceptions.

PubMed

Nelson, Craig E

2008-08-01

The strength of the evidence supporting evolution has increased markedly since the discovery of DNA but, paradoxically, public resistance to accepting evolution seems to have become stronger. A key dilemma is that science faculty have often continued to teach evolution ineffectively, even as the evidence that traditional ways of teaching are inferior has become stronger and stronger. Three pedagogical strategies that together can make a large difference in students' understanding and acceptance of evolution are extensive use of interactive engagement, a focus on critical thinking in science (especially on comparisons and explicit criteria) and using both of these in helping the students actively compare their initial conceptions (and publicly popular misconceptions) with more fully scientific conceptions. The conclusion that students' misconceptions must be dealt with systematically can be difficult for faculty who are teaching evolution since much of the students' resistance is framed in religious terms and one might be reluctant to address religious ideas in class. Applications to teaching evolution are illustrated with examples that address criteria and critical thinking, standard geology versus flood geology, evolutionary developmental biology versus organs of extreme perfection, and the importance of using humans as a central example. It is also helpful to bridge the false dichotomy, seen by many students, between atheistic evolution versus religious creationism. These applications are developed in detail and are intended to be sufficient to allow others to use these approaches in their teaching. Students and other faculty were quite supportive of these approaches as implemented in my classes.

On Gene Concepts and Teaching Genetics: Episodes from Classical Genetics

NASA Astrophysics Data System (ADS)

Burian, Richard M.

2013-02-01

This paper addresses the teaching of advanced high school courses or undergraduate courses for non-biology majors about genetics or history of genetics. It will probably be difficult to take the approach described here in a high school science course, although the general approach could help improve such courses. It would be ideal for a college course in history of genetics or a course designed to teach non-science majors how science works or the rudiments of the genetics in a way that will help them as citizens. The approach aims to teach the processes of discovery, correction, and validation by utilizing illustrative episodes from the history of genetics. The episodes are treated in way that should foster understanding of basic questions about genes, the sorts of techniques used to answer questions about the constitution and structure of genes, how they function, and what they determine, and some of the major biological disagreements that arose in dealing with these questions. The material covered here could be connected to social and political issues raised by genetics, but these connections are not surveyed here. As it is, to cover this much territory, the article is limited to four major episodes from Mendel's paper to the beginning of World War II. A sequel will deal with the molecularization of genetics and with molecular gene concepts through the Human Genome Project.

2018-04-01

Linear equation is one of the topics in mathematics that are considered difficult. Student difficulties of understanding linear equation can be caused by lack of understanding this concept and the way of teachers teach. TPACK is a way to understand the complex relationships between teaching and content taught through the use of specific teaching approaches and supported by the right technology tools. This study aims to identify TPACK of junior high school mathematics teachers in teaching linear equation. The method used in the study was descriptive. In the first phase, a survey using a questionnaire was carried out on 45 junior high school mathematics teachers in teaching linear equation. While in the second phase, the interview involved three teachers. The analysis of data used were quantitative and qualitative technique. The result PCK revealed teachers emphasized developing procedural and conceptual knowledge through reliance on traditional in teaching linear equation. The result of TPK revealed teachers’ lower capacity to deal with the general information and communications technologies goals across the curriculum in teaching linear equation. The result indicated that PowerPoint constitutes TCK modal technological capability in teaching linear equation. The result of TPACK seems to suggest a low standard in teachers’ technological skills across a variety of mathematics education goals in teaching linear equation. This means that the ability of teachers’ TPACK in teaching linear equation still needs to be improved.

To assess whether students find concept mapping a useful learning methodology to conceptualize and organize topics studied in CNS module of Pharmacology; and to evaluate whether addition of concept mapping assignment could help to improve examination scores. An analytical study. College of Dentistry, Jinnah Medical and Dental College, Karachi, Pakistan, from March to May 2009. A class of 50 BDS students was recruited for the study. Two randomly selected groups of 12 students each, prepared concept maps in topics from CNS pharmacology which were displayed and discussed during tutorial sessions. The other two groups (n = 25) following the traditional teaching methodology, served as controls. Scores from best choice questions and short essay questions were compared between the investigational and control groups using the student's t-test with significance at p < 0.05. Feedback obtained after completion of the study was evaluated as percent response. One-best-choice test of the control group showed a mean grade of 57.1 ± 16.7 vs. test group mean of 58.8 ± 13. For the short essay questions, control group obtained a mean of 52.3 ± 18.8 vs. test group mean grade of 53.8 ± 22.5. Both results were not significantly different (p > 0.05). However, feedback about concept mapping showed that the technique helped the students to conceptualize difficult topics in CNS pharmacology (86.36%). Concept mapping was particularly beneficial in preparing for exams as it provided a quick overview of the entire subject (68.68%). Students found concept mapping as a useful pedagogical tool which could potentially be used to acquire meaningful learning in Pharmacology as a supplement to traditional teaching techniques. It was not found beneficial in improving examination grades probably because standard examinations and concept mapping measure different cognitive domains.

Assessment of Spreadsheet-based Modules in a Physical Geology Course with Emphasis on the Effectiveness of the use of Excel

Lehto, H.; Vacher, H. L.

2013-12-01

Educators have used spreadsheets to teach math concepts for years. However, when spreadsheet-based modules began to be used to teach math and geology concepts at USF students found them difficult to use. Most often students expressed frustration that learning how to use Excel took precedence over learning the concepts presented in the modules. Was the Excel was getting in the way? To investigate this question, we placed students in Physical Geology courses into two groups: one group was given a set of modules that instructed them to use Excel for their calculations, while the modules given to the other group simple instructed them to do the calculations but they were not told what method to use. Our expectation was that students in the Non-Excel group would be less frustrated and thus attain a higher level of learning of the concepts presented in the modules. However, our results show that students had high gains for both the math and geology concepts presented in the modules whether Excel was used or not. We also tested the students' attitudes about the modules and the knowledge they gained and found that overall students were comfortable with the math and geology concepts presented in the modules, and most felt that the modules were worth their time; however they did not wish to complete any more modules. The only observed difference in gains was that students in the course led by the author of the modules had larger gains in knowledge versus those in the course led by another instructor. This difference may have been the result of differences in teaching style, such as the module author's mention and linking of the modules with lecture materials throughout the course. We believe that spreadsheet-based modules are a good tool for teaching math and geology concepts, as overall the students were confident in their new knowledge. We also found that the use of Excel within the module did not affect the learning outcomes. The one downside of this study was that after completing the modules the students did not wish to do any more, which may have to do with a strong tendency towards math avoidance.

Interactive computer simulations increase students' understanding of difficult concepts and their ability to explain complex ideas. We created a module of eight interactive programs and accompanying lesson plans for teaching the fundamental concepts of Nuclear Magnetic Resonance (NMR) and Magnetic Resonance Imaging (MRI) that we call interactive NMR (iNMR). We begin with an analogy between nuclear spins and metronomes to start to build intuition about the dynamics of spins in a magnetic field. We continue to explain T1, T2, and pulse sequences with the metronome analogy. The final three programs are used to introduce and explain the Magnetic Resonance Switch, a recent diagnostic technique based on NMR. A modern relevant application is useful to generate interest in the topic and confidence in the students' ability to apply their knowledge. The iNMR module was incorporated into a high school AP physics class. In a preliminary evaluation of implementation, students expressed enthusiasm and demonstrated enhanced understanding of the material relative to the previous year. Funded by NSF PHY-0646094 grant.

Understanding the geometry especially of three-dimensional space is still considered difficult by some students. Therefore, a learning innovation is required to overcome students’ difficulties in learning geometry. In this research, we developed geometry learning media based on augmented reality in android flatform’s then it was implemented in teaching three-dimensional objects for some junior high school students to find out: how is the students response in using this new media in geometry and is this media can solve the student’s difficulties in understanding geometry concept. The results showed that the use of geometry learning media based on augmented reality in android flatform is able to get positive responses from the students in learning geometry concepts especially three-dimensional objects and students more easy to understand concept of diagonal in geometry than before using this media.

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

2017-08-01

Polarization of light and the related knowledge are key and difficult points in optical teaching, and they are difficult to be understood since they are very abstract concepts. To help students understand the polarization properties of light, some classroom demonstration experiments have been constructed by employing the optical source, polarizers, wave plates optical cage system and polarization axis finder (PAF). The PAF is a polarization indicating device with many linear polarizing components concentric circles, which can visualize the polarization axis's direction of linearly polarized light intuitively. With the help of these demonstration experiment systems, the conversion and difference between the linear polarized light and circularly polarized light have been observed directly by inserting or removing a quarter-wave plate. The rotation phenomenon of linearly polarized light's polarization axis when it propagates through an optical active medium has been observed and studied in experiment, and the strain distribution of some mounted and unmounted lenses have also been demonstrated and observed in experiment conveniently. Furthermore, some typical polarization targets, such as liquid crystal display (LCD), polarized dark glass and skylight, have been observed based on PAF, which is quite suitable to help students understand these targets' polarization properties and the related physical laws. Finally, these demonstration experimental systems have been employed in classroom teaching of our university in physical optics, optoelectronics and photoelectric detection courses, and they are very popular with teachers and students.

How effective are simulated molecular-level experiments for teaching diffusion and osmosis?

PubMed

Meir, Eli; Perry, Judith; Stal, Derek; Maruca, Susan; Klopfer, Eric

2005-01-01

Diffusion and osmosis are central concepts in biology, both at the cellular and organ levels. They are presented several times throughout most introductory biology textbooks (e.g., Freeman, 2002), yet both processes are often difficult for students to understand (Odom, 1995; Zuckerman, 1994; Sanger et al., 2001; and results herein). Students have deep-rooted misconceptions about how diffusion and osmosis work, especially at the molecular level. We hypothesized that this might be in part due to the inability to see and explore these processes at the molecular level. In order to investigate this, we developed new software, OsmoBeaker, which allows students to perform inquiry-based experiments at the molecular level. Here we show that these simulated laboratories do indeed teach diffusion and osmosis and help overcome some, but not all, student misconceptions.

Students have deep-rooted misconceptions about how diffusion and osmosis work, especially at the molecular level. We hypothesized that this might be in part due to the inability to see and explore these processes at the molecular level. In order to investigate this, we developed new software, OsmoBeaker, which allows students to perform inquiry-based experiments at the molecular level. Here we show that these simulated laboratories do indeed teach diffusion and osmosis and help overcome some, but not all, student misconceptions. PMID:16220144

Development of a microlesson in teaching energy levels of atoms

NASA Astrophysics Data System (ADS)

Rodriguez, Cherilyn A.; Buan, Amelia T.

2018-01-01

Energy levels of atoms is one of the difficult topics in understanding atomic structure of matter. It appears tobe abstract, theoretical and needs visual representation and images. Hence, in this study a microlesson in teaching the high school chemistry concept on the energy levels of atoms is developed and validated. The researchers utilized backward curriculum design in planning the microlesson to meet the standards of the science K-12 curriculum. The planning process of the microlesson involved a) Identifying the learning competencies in K-12 science curriculum b) write learning objectives c) planning of assessment tools d) making a storyboard e) designing the microlesson and validate and revise the microlesson. The microlesson made use of varied resources in the internet from which the students accessed and collected information about energy levels of atoms. Working in groups, the students synthesized the information on how and why fireworks produce various colors of light through a post card. Findings of the study showed that there was an increase of achievement in learning the content and the students were highly motivated to learn chemistry. Furthermore, the students perceived that the microlesson helped them to understand the chemistry concept through the use of appropriate multimedia activities.

Questioning and metacognitive thinking: On-line and off-line assessments in understanding the role of prompting/questioning and metacognitive thinking in a digital learning environment

NASA Astrophysics Data System (ADS)

Schroeder, Mubina Khan

In science education, the use of digital technology-based learning can help students struggling with difficult concepts such as the movement of molecules. While digital learning tools hold much promise for science education, the question arises as to whether or not such technology can serve as an adequate surrogate for the teacher-student interactions that theorists like Lev Vygotsky (1978) underscored as being critical to learning. In response to such concerns, designers of digital curricula often utilize scaffolds to help students as they learn from such programs. Using a simulation designed to teach students about the concept of diffusion as an example, I examine the effect of including prompting language in the learning sequence of the simulation. The use of prompting language in digital curriculum appears to be successful because it elicits science students to reflect and metacognise about their learning, lending support to Vygotsky's (1978) ideas of teaching and learning involving outer and inner dialog. However, findings from think aloud data continue to underscore the importance of human linguistic exchange as a preferable learning paradigm.

This research aims to develop oxidation-reduction reactions (redox) teaching material used the Four Steps Teaching Material Development (4S TMD) method consists of four steps: selection, structuring, characterization and didactical reduction. This paper is the first part of the development of teaching material that includes selection and structuring steps. At the selection step, the development of teaching material begins with the development concept of redox based on curriculum demands, then the development of fundamental concepts sourced from the international textbook, and last is the development of values or skills can be integrated with redox concepts. The results of this selection step are the subject matter of the redox concept and values can be integrated with it. In the structuring step was developed concept map that provide on the relationship between redox concepts; Macro structure that guide systematic on the writing of teaching material; And multiple representations which are the development of teaching material that connection between macroscopic, submicroscopic, and symbolic level representations. The result of the two steps in this first part of the study produced a draft of teaching material. Evaluation of the draft of teaching material is done by an expert lecturer in the field of chemical education to assess the feasibility of teaching material.

A novel patchwork model used in lecture and laboratory to teach the three-dimensional organization of mesenteries.

PubMed

Noël, Geoffroy P J C

2013-01-01

Anatomy teaching is seeing a decline in both lecture and laboratory hours across many medical schools in North America. New strategies are therefore needed to not only make anatomy teaching more clinically integrated, but also to implement new interactive teaching techniques to help students more efficiently grasp the complex organization of the human body. Among the difficult anatomical concepts that students struggle to understand, the anatomy of the peritoneal cavity with its complex projections of peritoneum could benefit strongly from new learning aids. In this report, an innovative teaching tool is presented to engage students during both lecture and laboratory, and help them build three-dimensional (3D) mental maps of peritoneal cavity. The model consists of a patchwork of mesenteries and gut made from colored cloth stitched together onto a T-shirt to denote the origin and outflow of each peritoneum projection. As the lecturer wears the life-size model, the students can appreciate the 3D organization of the peritoneal cavity on a living body. In addition, the T-shirt model can be used in parallel with dissection to ensure a strong reinforcement of the spatial understanding of the peritoneal cavity.

The development of a digital logic concept inventory

NASA Astrophysics Data System (ADS)

Herman, Geoffrey Lindsay

Instructors in electrical and computer engineering and in computer science have developed innovative methods to teach digital logic circuits. These methods attempt to increase student learning, satisfaction, and retention. Although there are readily accessible and accepted means for measuring satisfaction and retention, there are no widely accepted means for assessing student learning. Rigorous assessment of learning is elusive because differences in topic coverage, curriculum and course goals, and exam content prevent direct comparison of two teaching methods when using tools such as final exam scores or course grades. Because of these difficulties, computing educators have issued a general call for the adoption of assessment tools to critically evaluate and compare the various teaching methods. Science, Technology, Engineering, and Mathematics (STEM) education researchers commonly measure students' conceptual learning to compare how much different pedagogies improve learning. Conceptual knowledge is often preferred because all engineering courses should teach a fundamental set of concepts even if they emphasize design or analysis to different degrees. Increasing conceptual learning is also important, because students who can organize facts and ideas within a consistent conceptual framework are able to learn new information quickly and can apply what they know in new situations. If instructors can accurately assess their students' conceptual knowledge, they can target instructional interventions to remedy common problems. To properly assess conceptual learning, several researchers have developed concept inventories (CIs) for core subjects in engineering sciences. CIs are multiple-choice assessment tools that evaluate how well a student's conceptual framework matches the accepted conceptual framework of a discipline or common faulty conceptual frameworks. We present how we created and evaluated the digital logic concept inventory (DLCI).We used a Delphi process to identify the important and difficult concepts to include on the DLCI. To discover and describe common student misconceptions, we interviewed students who had completed a digital logic course. Students vocalized their thoughts as they solved digital logic problems. We analyzed the interview data using a qualitative grounded theory approach. We have administered the DLCI at several institutions and have checked the validity, reliability, and bias of the DLCI with classical testing theory procedures. These procedures consisted of follow-up interviews with students, analysis of administration results with statistical procedures, and expert feedback. We discuss these results and present the DLCI's potential for providing a meaningful tool for comparing student learning at different institutions.

Asking a Great Question: A Librarian Teaches Questioning Skills to First-Year Medical Students.

PubMed

Adams, Nancy E

2015-01-01

In a single one-hour session, first-year medical students were taught a framework for differentiating between lower-order questions that lead to knowledge of facts and higher-order questions that lead to integration of concepts and deeper learning, thereby preparing them for problem-based learning (PBL). Students generated lists of questions in response to an assertion prompt and categorized them according to Bloom's Taxonomy. These data were analyzed in addition to data from the course exam, which asked them to formulate a higher-level question in response to a prompt. Categorizing questions according to Bloom's Taxonomy was a more difficult task for students than was formulating higher-order questions. Students reported that the skills that they learned were used in subsequent PBL sessions to formulate higher-order learning objectives that integrated new and previously-learned concepts.

Training hydrologists to be ecohydrologists: A ';how-you-can-do-it' example leveraging an active learning environment

2013-12-01

Structuring an education strategy capable of addressing the various spheres of ecohydrology is difficult due to the inter-disciplinary and cross-disciplinary nature of this emergent field. Clearly, there is a need for such strategies to accommodate more progressive educational concepts while highlighting a skills-based education. To demonstrate a possible way to develop courses that include such concepts, we offer a case-study or a ';how-you-can-do-it' example from an ecohydrology course recently co-taught by teachers from Stockholm University and Cornell University at Stockholm University's Navarino Environmental Observatory (NEO) in Costa Navarino, Greece. This course focused on introducing hydrology Master's students to some of the central concepts of ecohydrology while at the same time supplying process-based understanding relevant for characterizing evapotranspiration. As such, the main goal of the course was to explore central theories in ecohydrology and their connection to plant-water interactions and the water cycle in a semiarid environment. In addition to presenting this roadmap for ecohydrology course development, we explore the utility and effectiveness of adopting active teaching and learning strategies drawing from the suite of learn-by-doing, hands-on, and inquiry-based techniques in such a course. We test a gradient of ';activeness' across a sequence of three teaching and learning activities. Our results indicate that there was a clear advantage for utilizing active learning techniques in place of traditional lecture-based styles. In addition, there was a preference among the student towards the more ';active' techniques. This demonstrates the added value of incorporating even the simplest active learning approaches in our ecohydrology (or general) teaching.

Trying to assess if our students really understand the ideas we present in class can be difficult. Concept inventories are research-validated assessment tools that can provide us with data to better understand whether we are successful in the classroom. The idea for the Solar System Concept Inventory (SSCI) was born after realizing that no concept inventory currently available covered details regarding the formation and evolution of our solar system. Topics were selected by having faculty identify the key concepts they address when teaching about the solar system and interviewing students in order to identify common naive ideas and reasoning difficulties relating to these key topics. Beginning in fall of 2008, a national multi-institutional field test began which would eventually involve nearly 2500 students and 17 instructors from 10 different institutions. After each round of testing, a group of instructors from multiple institutions around the country worked together to analyze the data and revise or eliminate underperforming questions. Each question was examined using a combination of point biserial, percent correct on the pre-test, and item difficulty to determine if the question was properly differentiating student understanding while also ensuring the question was not too easy or too hard. In this talk, I will present an overall outline of the development of the SSCI as well as the final testing results. The final version of the SSCI can be found at http://casa.colorado.edu/ hornstei/ssci/. This material is based upon work supported by the National Science Foundation under Grant No. 0715517, a CCLI Phase III Grant for the Collaboration of Astronomy Teaching Scholars (CATS).

Using literature to help physician-learners understand and manage "difficult" patients.

PubMed

Shapiro, J; Lie, D

2000-07-01

Despite significant clinical and research efforts aimed at recognizing and managing "difficult" patients, such patients remain a frustrating experience for many clinicians. This is especially true for primary care residents, who are required to see a significant volume of patients with diverse and complex problems, but who may not have adequate training and life experience to enable them to deal with problematic doctor-patient situations. Literature--short stories, poems, and patient narratives--is a little-explored educational tool to help residents in understanding and working with difficult patients. In this report, the authors examine the mechanics of using literature to teach about difficult patients, including structuring the learning environment, establishing learning objectives, identifying teaching resources and appropriate pedagogic methods, and incorporating creative writing assignments. They also present an illustrative progression of a typical literature-based teaching session about a difficult patient.

Unpacking Exoplanet Detection Using Pedagogical Discipline Representations (PDRs)

Prather, Edward E.; Chambers, Timothy G.; Wallace, Colin Scott; Brissenden, Gina

2017-01-01

Successful educators know the importance of using multiple representations to teach the content of their disciplines. We have all seen the moments of epiphany that can be inspired when engaging with just the right representation of a difficult concept. The formal study of the cognitive impact of different representations on learners is now an active area of education research. The affordances of a particular representation are defined as the elements of disciplinary knowledge that students are able to access and reason about using that representation. Instructors with expert pedagogical content knowledge teach each topic using representations with complementary affordances, maximizing their students’ opportunity to develop fluency with all aspects of the topic. The work presented here examines how we have applied the theory of affordances to the development of pedagogical discipline representation (PDR) in an effort to provide access to, and help non-science-majors engage in expert-like reasoning about, general relativity as applied to detection of exoplanets. We define a pedagogical discipline representation (PDR) as a representation that has been uniquely tailored for the purpose of teaching a specific topic within a discipline. PDRs can be simplified versions of expert representations or can be highly contextualized with features that purposefully help unpack specific reasoning or concepts, and engage learners’ pre-existing mental models while promoting and enabling critical discourse. Examples of PDRs used for instruction and assessment will be provided along with preliminary results documenting the effectiveness of their use in the classroom.

Gibbs and Coffey (2004) have reported that teaching practices are influenced by teachers' conceptions of learning and teaching. In our previous research we found significant differences between teachers' conceptions in two medical schools with student-centred education. Medical school was the most important predictor, next to discipline, gender and teaching experience. Our research questions for the current study are (1) which specific elements of medical school explain the effect of medical school on teachers' conceptions of learning and teaching? How? and (2) which contextual and personal characteristics are related to conceptions of learning and teaching? How? Individual interviews were conducted with 13 teachers of the undergraduate curricula in two medical schools. Previously their conceptions of learning and teaching were assessed with the COLT questionnaire. We investigated the meanings they attached to context and personal characteristics, in relation to their conceptions of learning and teaching. We used a template analysis. Large individual differences existed between teachers. Characteristics mentioned at the medical school and curriculum level were 'curriculum tradition', 'support by educational department' and 'management and finances'. Other contextual characteristics were 'leadership style' at all levels but especially of department chairs, 'affordances and support', 'support and relatedness', and 'students' characteristics'. Personal characteristics were 'agency', 'experience with PBL (as a student or a teacher)','personal development', 'motivation and work engagement'and 'high content expertise'. Several context and personal characteristics associated with teachers' conceptions were identified, enabling a broader view on faculty development with attention for these characteristics, next to teaching skills.

Because there is little connection between physics concepts and real life, most students find physics very difficult. In this frontline I have provided a timely link of the historical development using the basic story of neutrino physics and integrated this into introductory modern physics courses in high schools or in higher education. In this way an instructor may be able to build on students’ curiosity in order to enhance the curriculum with some remarkable new physics. Using the history of science in the classroom shapes and improves students’ views and knowledge of the nature of science and increase students’ interest in physics.

The Sources of Science Teaching Self-efficacy among Elementary School Teachers: A mediational model approach

This study aimed to investigate the factors accounting for science teaching self-efficacy and to examine the relationships among Taiwanese teachers' science teaching self-efficacy, teaching and learning conceptions, technological-pedagogical content knowledge for the Internet (TPACK-I), and attitudes toward Internet-based instruction (Attitudes) using a mediational model approach. A total of 233 science teachers from 41 elementary schools in Taiwan were invited to take part in the study. After ensuring the validity and reliability of each questionnaire, the results indicated that each measure had satisfactory validity and reliability. Furthermore, through mediational models, the results revealed that TPACK-I and Attitudes mediated the relationship between teaching and learning conceptions and science teaching self-efficacy, suggesting that (1) knowledge of and attitudes toward Internet-based instruction (KATII) mediated the positive relationship between constructivist conceptions of teaching and learning and outcome expectancy, and that (2) KATII mediated the negative correlations between traditional conceptions of teaching and learning and teaching efficacy.

Elementary Teacher's Conceptions of Inquiry Teaching: Messages for Teacher Development

NASA Astrophysics Data System (ADS)

Ireland, Joseph E.; Watters, James J.; Brownlee, Jo; Lupton, Mandy

2012-02-01

This study explored practicing elementary school teacher's conceptions of teaching in ways that foster inquiry-based learning in the science curriculum (inquiry teaching). The advocacy for inquiry-based learning in contemporary curricula assumes the principle that students learn in their own way by drawing on direct experience fostered by the teacher. That students should be able to discover answers themselves through active engagement with new experiences was central to the thinking of eminent educators such as Pestalozzi, Dewey and Montessori. However, even after many years of research and practice, inquiry learning as a referent for teaching still struggles to find expression in the average teachers' pedagogy. This study drew on interview data from 20 elementary teachers. A phenomenographic analysis revealed three conceptions of teaching for inquiry learning in science in the elementary years of schooling: (a) The Experience-centered conception where teachers focused on providing interesting sensory experiences to students; (b) The Problem-centered conception where teachers focused on engaging students with challenging problems; and (c) The Question-centered conception where teachers focused on helping students to ask and answer their own questions. Understanding teachers' conceptions has implications for both the enactment of inquiry teaching in the classroom as well as the uptake of new teaching behaviors during professional development, with enhanced outcomes for engaging students in Science.

A historical study to understand students’ current difficulties about RMS values

NASA Astrophysics Data System (ADS)

Khantine-Langlois, Françoise; Munier, Valérie

2016-07-01

Several studies show that students experience more and more difficulties managing the measurements of electrical values in alternating current and that they have trouble making links between theory and practice. They find it difficult to give meaning to root mean square (RMS; or effective) values, which are not understood as average values and are confused with instantaneous values. This shows that students do not clearly differentiate variable and direct currents. In this paper we try, with a historical study and a study of teaching the concept of RMS values, to understand students’ difficulties with this concept. In the first part we present an epistemological analysis of the concept of RMS values, showing that it is multifaceted and can be approached from different points of view. In the second part we analyse the evolution of French secondary school curricula and textbooks from the explicit introduction of variable currents to today, questioning the links between the evolution of the curricula and the evolution of the place of science and technology in our societies. We point out that the evolution of the curricula is linked to the social context and to the connections between science, technology and society, and also to the relationship with mathematics curricula. We show that alternating current is introduced earlier in the curriculum but has gradually lost all phenomenological description. This study allows us to better understand students’ difficulties and to discuss some implications for teaching.

In addition, the effect of "TU Youyou" will not only improve the industry development, but also indicates the increasing international competition intensely. Therefore, one of the core problems of the sustainable-development industry is the training of senior talents under the "New Situation" with opportunity and intense competition. As one of the forefront courses of Chinese Pharmacology, Molecular Pharmacognosy (MP) is a new interdisciplinary science, which integrates the pharmacognosy and molecular biology, and combines many discipline theories and technological systems. MP not only inherits the traditional concepts,but also makes up for the shortages of pharmacognosy, and improves the development of pharmacognosy. Thus, these are importance of MP for cultivation of senior talents, and also the difficult teaching points of MP with no unified teaching mode. We will, in this paper, discuss the possible teaching modes through several aspects for talent cultivation and meeting the needs of social and industry development, such as teaching state of MP, the education of undergraduate and graduate students, social identity, and self renewal of curriculum theories and practice.

One goal of postsecondary education is to assist students in developing expert-level understanding. Previous attempts to encourage expert-level understanding of phylogenetic analysis in college science classrooms have largely focused on isolated, or “one-shot,” in-class activities. Using a deliberate practice instructional approach, we designed a set of five assignments for a 300-level plant systematics course that incrementally introduces the concepts and skills used in phylogenetic analysis. In our assignments, students learned the process of constructing phylogenetic trees through a series of increasingly difficult tasks; thus, skill development served as a framework for building content knowledge. We present results from 5 yr of final exam scores, pre- and postconcept assessments, and student surveys to assess the impact of our new pedagogical materials on student performance related to constructing and interpreting phylogenetic trees. Students improved in their ability to interpret relationships within trees and improved in several aspects related to between-tree comparisons and tree construction skills. Student feedback indicated that most students believed our approach prepared them to engage in tree construction and gave them confidence in their abilities. Overall, our data confirm that instructional approaches implementing deliberate practice address student misconceptions, improve student experiences, and foster deeper understanding of difficult scientific concepts.

2010-01-01

Objective To design and implement a demonstration project to teach interprofessional teams how to recognize and engage in difficult conversations with patients. Design Interdisciplinary teams consisting of pharmacy students and residents, student nurses, and medical residents responded to preliminary questions regarding difficult conversations, listened to a brief discussion on difficult conversations; formed ad hoc teams and interacted with a standardized patient (mother) and a human simulator (child), discussing the infant's health issues, intimate partner violence, and suicidal thinking; and underwent debriefing. Assessment Participants evaluated the learning methods positively and a majority demonstrated knowledge gains. The project team also learned lessons that will help better design future programs, including an emphasis on simulations over lecture and the importance of debriefing on student learning. Drawbacks included the major time commitment for design and implementation, sustainability, and the lack of resources to replicate the program for all students. Conclusion Simulation is an effective technique to teach interprofessional teams how to engage in difficult conversations with patients. PMID:21088725

Image and video-based results and process control are essential tools of a new teaching concept for conveying surgical skills. The new teaching concept integrates approved teaching principles and new media. Every performance of exercises is videotaped and the result photographically recorded. The quality of the process and result becomes accessible for an analysis by the teacher and the student/learner. The learner is instructed to perform a criteria-based self-analysis of the video and image material by themselves. The new learning concept has so far been successfully applied in seven rounds within the newly designed modular class "Intensivkurs Chirurgische Techniken" (Intensive training of surgical techniques). Result documentation and analysis via digital picture was completed by almost every student. The quality of the results was high. Interestingly the result quality did not correlate with the time needed for the exercise. The training success had a lasting effect. The new and elaborate concept improves the quality of teaching. In the long run resources for patient care should be saved when training students according to this concept prior to performing tasks in the operating theater. These resources should be allocated for further refining innovative teaching concepts.

Enhanced podcasts for teaching biochemistry to veterinary students.

Gough, Kevin C

2011-01-01

The teaching of biochemistry within medical disciplines presents certain challenges; firstly to relay a large body of complex facts and abstract concepts, and secondly to motivate students that this relatively difficult topic is worth their time to study. Here, nutrient biochemistry was taught within a multidisciplinary module as part of an undergraduate veterinary curriculum. The teaching approach was initially focussed on a mixture of didactic lectures and student-centred activities such as directed group/self learning. In subsequent years the core didactic lectures were replaced with enhanced podcasts covering the same material, along with the introduction of student presentations delivered within groups with both peer and facilitator assessment. These changes were accompanied by an increase in the time dedicated to this topic to allow sufficient time for students to work through podcasts and prepare presentations. The combination of these changes resulted in significant improvements in student performance within an in-course biochemistry long essay. These changes in the teaching approach, and particularly the introduction of extensive podcasts, was well received by students who perceived the process of going through the podcasts as time consuming but allowing them flexibility in both the pace that they studied this topic as well as the location and times that they studied it.

Medicinal chemistry and pharmacology are difficult topics to both teach and learn given the complex nature of drug mechanisms and drug-receptor interactions. This highlights the need for innovative teaching methods to deliver this information to students. One such method is through three-dimensional (3D) printing of enzymes and ligands in the teaching of molecular modelling concepts relating to drug-receptor and enzyme interactions be ligands. This type of printing has been shown to be beneficial in several educational settings; however, to our knowledge, its effectiveness in pharmacy, medicinal chemistry and pharmacology learning and teaching is largely unknown. Therefore, the aim of this study was to evaluate pharmacy student perceptions and the educational benefits of 3D printed molecules in molecular modelling with regards to engagement and learning outcomes when used in a drug-target interaction topic. This aim was achieved through administering students a short questionnaire designed to evaluate their engagement and learning outcomes with students also free to provide comments. This study found that nearly all (>90%) students found the activity was useful in improving both student engagement and learning outcomes. In conclusion, 3D printing may provide an alternative learning activity to help pharmacy students understand the drug-target interaction. Copyright © 2017 Elsevier Inc. All rights reserved.

Using History to Teach Mathematics: The Case of Logarithms

NASA Astrophysics Data System (ADS)

Panagiotou, Evangelos N.

2011-01-01

Many authors have discussed the question why we should use the history of mathematics to mathematics education. For example, Fauvel (For Learn Math, 11(2): 3-6, 1991) mentions at least fifteen arguments for applying the history of mathematics in teaching and learning mathematics. Knowing how to introduce history into mathematics lessons is a more difficult step. We found, however, that only a limited number of articles contain instructions on how to use the material, as opposed to numerous general articles suggesting the use of the history of mathematics as a didactical tool. The present article focuses on converting the history of logarithms into material appropriate for teaching students of 11th grade, without any knowledge of calculus. History uncovers that logarithms were invented prior of the exponential function and shows that the logarithms are not an arbitrary product, as is the case when we leap straight in the definition given in all modern textbooks, but they are a response to a problem. We describe step by step the historical evolution of the concept, in a way appropriate for use in class, until the definition of the logarithm as area under the hyperbola. Next, we present the formal development of the theory and define the exponential function. The teaching sequence has been successfully undertaken in two high school classrooms.

Technological advances that enhance teaching using animals, and the application of the Three Rs.

Davies, Alexander S

The inventions that have progressively contributed to education have never offered opportunities as vast as in the digital era, even though this is still scarcely 25 years old. In this time, digital handling of data led first to text processing, then to bitmap and vector graphics, and now, to digital sound and movies. As these advanced, the storage methods became larger, faster, easier and cheaper. The advancement of technology has been so rapid that the standard of most teaching aids now available is well below what can currently be achieved. We are confronted with an unprecedented opportunity for applying the principles of reduction, refinement and replacement of animals in education. Not only are the visual teaching aids improved by digitising, but all aspects of their development, including the ease, higher speed, and low cost of creation, editing, copying, distribution and access, are improved, as well. Several examples will be given, including access to interactive panoramic movies, animated sequences to explain difficult concepts, on-line tutorials and image databases using digital photography, radiography and other diagnostic methods, as well as the production of desktop movies. The speed of technical advance brings its own problems, but the challenges and possibilities for developing viable alternatives to the use of animals in teaching are vast.

Interactive Web-based tutorials for teaching digital electronics

Bailey, Donald G.

2000-10-01

With a wide range of student abilities in a class, it is difficult to effectively teach and stimulate all students. A series of web based tutorials was designed to help weaker students and stretch the stronger students. The tutorials consist of a series of HTML web pages with embedded Java applets. This combination is particularly powerful for providing interactive demonstrations because any textual content may be easily provided within the web page. The applet is able to be a compete working program that dynamically illustrates the concept, or provides a working environment for the student to experiment and work through their solution. The applet is dynamic, and responds to the student through both mouse clicks and keyboard entry. These allow the student to adjust parameters, make selections, and affect the way the program is run or information is displayed. Such interaction allows each applet to provide a mini demonstration or experiment to help the student understand a particular concept or technique. The approach taken is illustrated with a tutorial that dynamically shows the relationships between a truth table, Karnaugh amp, logic circuit and Boolean algebra representations of a logic function, and dramatically illustrates the effect of minimization on the resultant circuit. Use of the tutorial has resulted in significant benefits, particularly with weaker students.

From surprise to cognition: Some effects of the structure of C.A.L. simulation programs on the cognitive and scientific activities of young adults

NASA Astrophysics Data System (ADS)

Dicker, R. J.

The main objective of this thesis is to describe the effect on cognition of the structure of CAL simulation programs used, in science teaching. Four programs simulating a pond ecosystem were written so as to present a simulation model and to assist in cognition in different ways. Various clinically detailed methods of describing learning were developed and tried including concept maps which were found to be sammative rather than formative descriptions of learning, and to be ambiguous) and hierarchical structures (which were found to be difficult to produce). Fran these concept maps and hierarchical structures I developed my Interaction Model of Learning which can be used to describe the chronological events concerned with cognition. Using the Interaction Model, the nature of cognition and the effect that CAL program structure has on this process is described. Various scenarios are presented as a means of showing the possible effects of program structure on learning. Four forms of concept learning activity and their relationship to learning valid and alternative conceptions are described. The findings from the study are particularly related to the work of Driver (1983), Marton (1976) and Entwistle (1981).

Constructing the integral concept on the basis of the idea of accumulation: suggestion for a high school curriculum

NASA Astrophysics Data System (ADS)

Kouropatov, Anatoli; Dreyfus, Tommy

2013-07-01

Students have a tendency to see integral calculus as a series of procedures with associated algorithms and many do not develop a conceptual grasp giving them the desirable versatility of thought. Thus, instead of a proceptual view of the symbols in integration, they have, at best, a process-oriented view. On the other hand, it is not surprising that many students find concepts such as the integral difficult when they are unable to experience these processes directly in the classroom. With a view towards improving this situation, constructing the integral concept on the basis of the idea of accumulation has been proposed (Educ Stud Math. 1994;26:229-274; Integral as accumulation: a didactical perspective for school mathematics; Thessaloniki: PME; 2009. p. 417-424). In this paper, we discuss a curriculum that is based on this idea and a design for curriculum materials that are intended to develop an improved cognitive base for a flexible proceptual understanding of the integral and integration in high school. The main focus is on how we (mathematics teachers and mathematics educators) might teach the integral concept in order to help high school students to construct meaningful knowledge alongside acquiring technical abilities.

Secondary Physical Science Teachers' Conceptions of Science Teaching in a Context of Change

Taylor, Dale L.; Booth, Shirley

2015-05-01

Pre-service teachers enter initial teacher education programmes with conceptions of teaching gleaned from their own schooling. These conceptions, which include teachers' beliefs, may be resistant to change, which is a challenge in contexts where teacher educators hope that teachers will teach in ways different from their own schooling. Conceptions of teaching found in different cultural and disciplinary contexts have contextual differences but have resonances with the results of research into teacher beliefs. Our sample of eight South African secondary physical science teachers was schooled in a system which encouraged knowledge transmission, but they were prepared in their initial teacher education for a learner-centred approach. After they had taught for a few years, we explored their conceptions of science teaching, using phenomenographic interviews. Four conceptions emerged inductively from the analysis: transferring science knowledge from mind to mind; transferring problematic science knowledge from mind to mind; creating space for learning science knowledge and creating space for learning problematic science knowledge. Internally these conceptions are constituted by three dimensions of variation: the nature of the science knowledge to be learnt, the role of the students and the role of the teacher. Media and practical work play different roles in the external horizon of these conceptions. These conceptions reflect the disciplinary context as well as the emphases of the sample's initial teacher education programme. This suggests that initial teacher education can significantly shape teachers' conceptions of teaching.

2011-11-01

This article describes the evolution of prospective primary teachers' conceptions of the methodology of teaching. Three categories were analyzed: the concept of activity, the organization of activities, and the concept of teaching resources. The study was conducted with five teams of prospective teachers, who were participating in teacher education courses of a constructivist orientation. The results showed very different itineraries in the processes of change, and the presence of two major obstacles—the belief that teaching is the direct cause of learning, and epistemological absolutism. The study allows us to deduce some implications for initial teacher education.

2015-01-01

Interpreting an electrocardiogram (ECG) is not only one of the most important parts of diagnostics but also one of the most difficult areas to teach. Owing to the abstract nature of the basic theoretical knowledge of the ECG, its scattered characteristics, and tedious and difficult-to-remember subject matter, teaching how to interpret ECGs is as difficult for teachers to teach as it is for students to learn. In order to enable medical students to master basic knowledge of ECG interpretation skills in a limited teaching time, we modified the content used for traditional ECG teaching and now propose a new ECG teaching method called the "graphics-sequence memory method." A prospective randomized controlled study was designed to measure the actual effectiveness of ECG learning by students. Two hundred students were randomly placed under a traditional teaching group and an innovative teaching group, with 100 participants in each group. The teachers in the traditional teaching group utilized the traditional teaching outline, whereas the teachers in the innovative teaching group received training in line with the proposed teaching method and syllabus. All the students took an examination in the final semester by analyzing 20 ECGs from real clinical cases and submitted their ECG reports. The average ECG reading time was 32 minutes for the traditional teaching group and 18 minutes for the innovative teaching group. The average ECG accuracy results were 43% for the traditional teaching group and 77% for the innovative teaching group. Learning to accurately interpret ECGs is an important skill in the cardiac discipline, but the ECG's mechanisms are intricate and the content is scattered. Textbooks tend to make the students feel confused owing to the restrictions of the length and the format of the syllabi, apart from many other limitations. The graphics-sequence memory method was found to be a useful method for ECG teaching.

What is biomedical informatics?

PubMed Central

Bernstam, Elmer V.; Smith, Jack W.; Johnson, Todd R.

2009-01-01

Biomedical informatics lacks a clear and theoretically grounded definition. Many proposed definitions focus on data, information, and knowledge, but do not provide an adequate definition of these terms. Leveraging insights from the philosophy of information, we define informatics as the science of information, where information is data plus meaning. Biomedical informatics is the science of information as applied to or studied in the context of biomedicine. Defining the object of study of informatics as data plus meaning clearly distinguishes the field from related fields, such as computer science, statistics and biomedicine, which have different objects of study. The emphasis on data plus meaning also suggests that biomedical informatics problems tend to be difficult when they deal with concepts that are hard to capture using formal, computational definitions. In other words, problems where meaning must be considered are more difficult than problems where manipulating data without regard for meaning is sufficient. Furthermore, the definition implies that informatics research, teaching, and service should focus on biomedical information as data plus meaning rather than only computer applications in biomedicine.

Geometry is the most important branch in mathematics. The purpose of teaching this material is to develop students' level of thinking for a better understanding. Otherwise, geometry in particular, has contributed students' failure in mathematics examinations. This problem occurs due to special feature in geometry which has complexity of correlation among its concept. This relates to mathematical connection. It is still difficult for students to improve this ability. This is because teachers' lack in facilitating students towards it. Eventhough, facilitating students can be in the form of teaching material. A learning module can be a solution because it consists of series activities that should be taken by students to achieve a certain goal. A series activities in this case is adopted by the phases of discovery-based learning model. Through this module, students are facilitated to discover concept by deep instruction and guidance. It can build the mathematical habits of mind and also strengthen the mathematical connection. Method used in this research was ten stages of research and development proposed by Bord and Gall. The research purpose is to create a valid learning module to improve students' mathematical connection in teaching quadrilateral. The retrieved valid module based on media expert judgment is 2,43 for eligibility chart aspect, 2,60 for eligibility presentation aspect, and 3,00 for eligibility contents aspect. Then the retrieved valid module based on material expert judgment is 3,10 for eligibility content aspect, 2,87 for eligibility presentation aspect, and 2,80 for eligibility language and legibility aspect.

2013-04-01

Diversity and differentiation within our classrooms, at all levels of education, is nowadays a fact. It has been one of the biggest challenges for educators to respond to the needs of all students in such a mixed-ability classroom. Teachers' inability to deal with students with different levels of readiness in a different way leads to school failure and all the negative outcomes that come with it. Differentiation of teaching and learning helps addressing this problem by respecting the different levels that exist in the classroom, and by responding to the needs of each learner. This article presents an action research study where a team of mathematics instructors and an expert in curriculum development developed and implemented a differentiated instruction learning environment in a first-year engineering calculus class at a university in Cyprus. This study provides evidence that differentiated instruction has a positive effect on student engagement and motivation and improves students' understanding of difficult calculus concepts.

Animated Cell Biology: A Quick and Easy Method for Making Effective, High-Quality Teaching Animations

PubMed Central

2006-01-01

There is accumulating evidence that animations aid learning of dynamic concepts in cell biology. However, existing animation packages are expensive and difficult to learn, and the subsequent production of even short animations can take weeks to months. Here I outline the principles and sequence of steps for producing high-quality PowerPoint animations in less than a day that are suitable for teaching in high school through college/university. After developing the animation it can be easily converted to any appropriate movie file format using Camtasia Studio for Internet or classroom presentations. Thus anyone who can use PowerPoint has the potential to make animations. Students who viewed the approximately 3-min PowerPoint/Camtasia Studio animation “Calcium and the Dual Signalling Pathway” over 15 min scored significantly higher marks on a subsequent quiz than those who had viewed still graphics with text for an equivalent time. In addition, results from student evaluations provided some data validating the use of such animations in cell biology teaching with some interesting caveats. Information is also provided on how such animations can be modified or updated easily or shared with others who can modify them to fit their own needs. PMID:17012217

Teaching-materials study of the elementary science using an extraterrestrial material

The schoolchild of a Japan likes the universe primarily and an inquisitive mind is also considered to be a high. It appears also in children having raised interest concern to astronomical phenomena, such as the space probe "Hayabusa", solar eclipse, and solar Face passage of Venus, in recent Japan. However, generally aside from a child's interest concern, a time and a space concept are difficult for the astronomical phenomenon requested by school education. It is a big problem not only for student but also for teacher. In this presentation, we propose the teaching-materials development which used a meteorite and cosmic dust. Since these teaching materials can touch thing, a student actually taking in his hand, or observing under a microscope, leading to the study understanding accompanied by realization is expected. It looks up at and observes a Star Burst and a constellation. However, acquisition of recognition that it is possible to take in its hand simultaneously and to observe is important. About the meteorite to observe, we can purchase from a special contractor. About cosmic dust, the sample extraction from the concrete floor of the roof of a school building is possible.

From biology to mathematical models and back: teaching modeling to biology students, and biology to math and engineering students.

PubMed

Chiel, Hillel J; McManus, Jeffrey M; Shaw, Kendrick M

2010-01-01

We describe the development of a course to teach modeling and mathematical analysis skills to students of biology and to teach biology to students with strong backgrounds in mathematics, physics, or engineering. The two groups of students have different ways of learning material and often have strong negative feelings toward the area of knowledge that they find difficult. To give students a sense of mastery in each area, several complementary approaches are used in the course: 1) a "live" textbook that allows students to explore models and mathematical processes interactively; 2) benchmark problems providing key skills on which students make continuous progress; 3) assignment of students to teams of two throughout the semester; 4) regular one-on-one interactions with instructors throughout the semester; and 5) a term project in which students reconstruct, analyze, extend, and then write in detail about a recently published biological model. Based on student evaluations and comments, an attitude survey, and the quality of the students' term papers, the course has significantly increased the ability and willingness of biology students to use mathematical concepts and modeling tools to understand biological systems, and it has significantly enhanced engineering students' appreciation of biology.

International Schools for Young Astronomers Teaching for Astronomy Development: two programmes of the International Astronomical Union

NASA Astrophysics Data System (ADS)

Gerbaldi, Michèle; DeGreve, Jean-Pierre; Guinan, Edward

2011-06-01

This text outlines the main features of two educational programmes of the International Astronomical Union (IAU): the International Schools for Young Astronomers (ISYA) and the Teaching for Astronomy Development programme (TAD), developed since 1967. The main goal of the International Schools for Young Astronomers (ISYA) is to support astronomy (education and research) in developing countries in organizing a 3-week School for students with typically M.Sc. degrees. The context in which the ISYA were developed changed drastically during the last decade. From a time when access to large telescopes was difficult and mainly organized on a nation-basis, nowadays the archives of astronomical data have accumulated at the same time that many major telescope become accessible, and they are accessible from everywhere, the concept of virtual observatory reinforcing this access. A second programme of the IAU, Teaching for Astronomy Development (TAD), partially based on a School, but also of shorter duration (typically one week) has a complementary objective. It is dedicated to assist countries that have little or no astronomical activity, but that wish to enhance their astronomy education. The fast development of the TAD programme over the past years is emphasized.

In the middle grades, students characteristically conflate mass and density, and even after instruction many students do not distinguish them consistently (Smith, Maclin, Grosslight, & Davis, 1997). Few develop a conceptualization of density that accounts for the implications of changing mass, volume, temperature, and/or state. My work looks specifically at how students make sense of the relationship between mass and volume as they refine their understanding of density. The concept of density is challenging to teach. Traditional methods of teaching density in middle-school classrooms typically involve either the measurement of an object's mass and volume and the subsequent calculation of the ratio of the two quantities, or the observation of different materials in water to learn about their buoyancy. Unfortunately, as Carol Smith and her colleagues have documented (1985, 1992, 1997), these approaches leave many students stuck in their "commonsense frameworks" that merge mass and density into one concept. Teachers need better ways to teach density. Hence I designed an intervention to study the effects of some possibly more effective ways to teach density. I developed and taught a complex intervention (Brown, 1992) featuring student modeling, extensive student dialogue on data and data analyses, formative assessments, the substitution of hands-on inquiry for mathematical problem sets, and multiple thought experiments. The hallmarks of the intervention were modeling and student dialogue, and the research question I posed was: Does classroom practice that encourages modeling with open-ended discourse help students differentiate between the concepts of mass and density? I patterned my research on a Smith study of density instruction in eighth grade (Smith, Maclin, Grosslight, & Davis, 1997), which had a quasiexperimental research design that compared the results of teaching density differently in two classrooms. I selected an intervention class and a comparison class from those I was teaching. The core of the density curriculum was similar in both classes. Instead of the intervention, though, the comparison class closely followed the lesson sequences provided by the classroom textbook, which tended to focus on formal and formulaic density instruction. I modified Smith's assessments for sixth graders. After teaching one class the intervention curriculum and the other the textbook-based curriculum, I evaluated and compared the progress of research participants in both classrooms by means of a pre- and post-instruction clinical interview, a pre- and post-instruction written test, and the end-of-chapter test from the textbook used in the comparison classroom. The results of my study were consistent: the intervention students outperformed and showed greater improvement on all assessments compared to the comparison students. In this study, modeling and student discourse were more effective ways to teach density than a standard textbook-based lesson sequence. The intervention helped students start to disrupt the conflation of mass and density, fostering both the comprehension of volume as a variable property of matter, and a nuanced understanding of density beyond formulaic reasoning. This dissertation is a report of my study for two audiences---academics and science educators. For the latter, I include recommendations for improving density instruction that are informed by my research.

Toward using games to teach fundamental computer science concepts

NASA Astrophysics Data System (ADS)

Edgington, Jeffrey Michael

Video and computer games have become an important area of study in the field of education. Games have been designed to teach mathematics, physics, raise social awareness, teach history and geography, and train soldiers in the military. Recent work has created computer games for teaching computer programming and understanding basic algorithms. We present an investigation where computer games are used to teach two fundamental computer science concepts: boolean expressions and recursion. The games are intended to teach the concepts and not how to implement them in a programming language. For this investigation, two computer games were created. One is designed to teach basic boolean expressions and operators and the other to teach fundamental concepts of recursion. We describe the design and implementation of both games. We evaluate the effectiveness of these games using before and after surveys. The surveys were designed to ascertain basic understanding, attitudes and beliefs regarding the concepts. The boolean game was evaluated with local high school students and students in a college level introductory computer science course. The recursion game was evaluated with students in a college level introductory computer science course. We present the analysis of the collected survey information for both games. This analysis shows a significant positive change in student attitude towards recursion and modest gains in student learning outcomes for both topics.

Water Plan 2030: A Dynamic Education Model for Teaching Water Management Issues

NASA Astrophysics Data System (ADS)

Rupprecht, C.; Washburne, J.; Lansey, K.; Williams, A.

2006-12-01

Dynamic educational tools to assist teachers and students in recognizing the impacts of water management decisions in a realistic context are not readily available. Water policy issues are often complex and difficult for students trying to make meaningful connections between system components. To fill this need, we have developed a systems modeling-based educational decision support system (DSS) with supplementary materials. This model, called Water Plan 2030, represents a general semi-arid watershed; it allows users to examine water management alternatives by changing input values for various water uses and basin conditions and immediately receive graphical outputs to compare decisions. The main goal of our DSS model is to foster students' abilities to make knowledgeable decisions with regard to water resources issues. There are two reasons we have developed this model for traditional classroom settings. First, the DSS model provides teachers with a mechanism for educating students about inter-related hydrologic concepts, complex systems and facilitates discussion of water resources issues. Second, Water Plan 2030 encourages student discovery of cause/effect relationships in a dynamic, hands-on environment and develops the ability to realize the implications of water management alternatives. The DSS model has been utilized in an undergraduate, non-major science class for 5 course hours, each of the past 4 semesters. Accompanying the PC-based model are supplementary materials to improve the effectiveness of implementation by emphasizing important concepts and guiding learners through the model components. These materials include in-class tutorials, introductory questions, role-playing activities and homework extensions that have been revised after each user session, based on student and instructor feedback. Most recently, we have developed individual lessons that teach specific model functions and concepts. These modules provide teachers the flexibility to adapt the model to meet numerous teaching goals. Evaluation results indicate that students improved their understanding of fundamental concepts and system interactions and showed the most improvement in questions related to water use by sector and sustainability issues. Model modifications have also improved student feedback of the model effectiveness and user- friendliness. Positive results from this project have created the demand for a web-based version, which will be online in late 2006.

Detecting changes in student teachers' conceptions of teaching science to adolescent English language learners

NASA Astrophysics Data System (ADS)

Pomeroy, Jonathon Richard

2000-10-01

This research study investigated the changes that occurred in six student teachers' conceptions of teaching science to adolescent English language learners over the duration of their participation in a one-year, graduate level, science teacher education program. Cases were created for each of the student teachers based on their concept maps, writing samples, interviews, lesson plans, informal interviews with cooperating teachers, and observation notes collected on biweekly visitations. The cases were divided into three dyads each consisting of two student teachers with similar preprogram and student teaching experiences. Cross case analysis revealed the existence of seven themes related to teaching science to adolescent English language learners. Further analysis suggested that student teachers that worked with experienced cooperating teachers and who had achieved a sense of autonomy over their student teaching demonstrated broad and sophisticated growth across all seven themes. Student teachers who had not achieved a sense of autonomy, demonstrated growth in two to three themes. Student teachers who demonstrated broad and sophisticated growth were able to clearly articulate their conceptions of teaching science to English language learners where as those who demonstrated limited growth were not. This research establishes the use of concept maps as a tool for detecting changes in student teachers' conceptions of teaching science to adolescent English language learners as well as the sensitivity of concept maps to detect the types of changes historically detected by writing samples and interviews. Recommendations based on the implications from are included.

Evaluation of competence-based teaching in higher education: From theory to practice.

PubMed

Bergsmann, Evelyn; Schultes, Marie-Therese; Winter, Petra; Schober, Barbara; Spiel, Christiane

2015-10-01

Competence-based teaching in higher education institutions and its evaluation have become a prevalent topic especially in the European Union. However, evaluation instruments are often limited, for example to single student competencies or specific elements of the teaching process. The present paper provides a more comprehensive evaluation concept that contributes to sustainable improvement of competence-based teaching in higher education institutions. The evaluation concept considers competence research developments as well as the participatory evaluation approach. The evaluation concept consists of three stages. The first stage evaluates whether the competencies students are supposed to acquire within the curriculum (ideal situation) are well defined. The second stage evaluates the teaching process and the competencies students have actually acquired (real situation). The third stage evaluates concrete aspects of the teaching process. Additionally, an implementation strategy is introduced to support the transfer from the theoretical evaluation concept to practice. The evaluation concept and its implementation strategy are designed for internal evaluations in higher education and primarily address higher education institutions that have already developed and conducted a competence-based curriculum.

2015-06-01

This study investigated how fifth-grade children's concept images of the unit fractions represented by the symbols , , and changed as a result of their participation in an instructional intervention based on multiple embodiments of fraction concepts. The participants' concept images were examined through pre- and post-teaching written questions and pre- and post-teaching one-to-one verbal interview questions. Results showed that at the pre-teaching stage, the student concept images of unit fractions were very narrow and mainly linked to area models. However, after the instructional intervention, the fifth graders were able to select and apply a variety of models in response to unit fraction tasks, and their concept images of unit fractions were enriched and linked to capacity, perimeter, linear and discrete models, as well as to area models. Their performances on tests had improved, and their conceptual understandings of unit fractions had developed.

VERT, a virtual clinical environment, enhances understanding of radiation therapy planning concepts.

PubMed

Leong, Aidan; Herst, Patries; Kane, Paul

2018-06-01

The ability to understand treatment plan dosimetry and apply this understanding clinically is fundamental to the role of the radiation therapist. This study evaluates whether or not the Virtual Environment for Radiotherapy Training (VERT) contributes to teaching treatment planning concepts to a cohort of first-year radiation therapy students. We directly compared a custom-developed VERT teaching module with a standard teaching module with respect to the understanding of treatment planning concepts using a cross-over design. Students self-reported their understanding of specific concepts before and after delivery of the VERT and standard teaching modules and evaluated aspects of VERT as a learning experience. In addition, teaching staff participated in a semi-structured interview discussing the modules from an educational perspective. Both the standard teaching module and VERT teaching module enhanced conceptual understanding and level of confidence in the student cohort after both teaching periods. The proportion of students reporting a perceived increase in knowledge/confidence was similar for the VERT teaching module for all but two scenarios. We propose that an integrated approach, providing a strong theoretical conceptual framework, followed by VERT to situate this framework in the (simulated) clinical environment combines the best of both teaching approaches. This study has established for the first time a clear role for a tailored VERT teaching module in teaching RT planning concepts because of its ability to visualise conceptual information within a simulated clinical environment. © 2018 The Authors.

A multimedia approach for teaching human embryology: Development and evaluation of a methodology.

PubMed

Moraes, Suzana Guimarães; Pereira, Luis Antonio Violin

2010-12-20

Human embryology requires students to understand the simultaneous changes in embryos, but students find it difficult to grasp the concepts presented and to visualise the related processes in three dimensions. The aims of this study have been to develop and evaluate new educational materials and a teaching methodology based on multimedia approaches to improve the comprehension of human development. The materials developed at the State University of Campinas include clinical histories, movies, animations, and ultrasound, as well as autopsy images from embryos and foetuses. The series of embryology lectures were divided into two parts. The first part of the series addressed the development of the body's structures, while in the second part, clinical history and the corresponding materials were shown to the students, who were encouraged to discuss the malformations. The teaching materials were made available on software used by the students in classes. At the end of the discipline, the material and methodology were evaluated with an attitudinal instrument, interviews, and knowledge examination. The response rate to the attitudinal instrument was 95.35%, and the response rate to the interview was 46%. The students approved of the materials and the teaching methodology (reliability of the attitudinal instrument was 0.9057). The exams showed that most students scored above 6.0. A multimedia approach proved useful for solving an important problem associated with teaching methods in many medical institutions: the lack of integration between basic sciences and clinical disciplines. 2010 Elsevier GmbH.

Integrating the New Generation Science Standards (NGSS) into K- 6 teacher training and curricula

NASA Astrophysics Data System (ADS)

Pinter, S.; Carlson, S. J.

2017-12-01

The Next Generation Science Standards is an initiative, adopted by 26 states, to set national education standards that are "rich in content and practice, arranged in a coherent manner across disciplines and grades to provide all students an internationally benchmarked science education." Educators now must integrate these standards into existing curricula. Many grade-school (K-6) teachers face a particularly daunting task, as they were traditionally not required to teach science or only at a rudimentary level. The majority of K-6 teachers enter teaching from non-science disciplines, making this transition even more difficult. Since the NGSS emphasizes integrated and coherent progression of knowledge from grade to grade, prospective K-6 teachers must be able to deliver science with confidence and enthusiasm to their students. CalTeach/MAST (Mathematics and Science Teaching Program) at the University of California Davis, has created a two-quarter sequence of integrated science courses for undergraduate students majoring in non-STEM disciplines and intending to pursue multiple-subject K-6 credentials. The UCD integrated science course provides future primary school teachers with a basic, but comprehensive background in the physical and earth/space sciences. Key tools are taught for improving teaching methods, investigating complex science ideas, and solving problems relevant to students' life experiences that require scientific or technological knowledge. This approach allows prospective K-6 teachers to explore more effectively the connections between the disciplinary core ideas, crosscutting concepts, and scientific and engineering practices, as outlined in the NGSS. In addition, they develop a core set of science teaching skills based on inquiry activities and guided lab discussions. With this course, we deliver a solid science background to prospective K-6 teachers and facilitate their ability to teach science following the standards as articulated in the NGSS.

2017-10-20

Undergraduate students majoring in forestry generally reflect that genetics is one of the most difficult compul-sory courses, because the traditional teaching method is difficult to satisfy their needs. According to the theoretical charac-teristics of forestry and actual demands of the students, in the light of teaching and research experience in recent years, we adopted a series of typical genetic cases such as 'opening coffin to identify relatives', stem-throne of Lycium ruthenicum Murr, and magic powers in Harry Potter. Our practices revealed that the case teaching in genetics could train good personality traits, learning abilities and creativity of the students, stimulate their interests and initiatives in learning, and increase systematic learning.

The Genetic Drift Inventory: A Tool for Measuring What Advanced Undergraduates Have Mastered about Genetic Drift

PubMed Central

Price, Rebecca M.; Andrews, Tessa C.; McElhinny, Teresa L.; Mead, Louise S.; Abraham, Joel K.; Thanukos, Anna; Perez, Kathryn E.

2014-01-01

Understanding genetic drift is crucial for a comprehensive understanding of biology, yet it is difficult to learn because it combines the conceptual challenges of both evolution and randomness. To help assess strategies for teaching genetic drift, we have developed and evaluated the Genetic Drift Inventory (GeDI), a concept inventory that measures upper-division students’ understanding of this concept. We used an iterative approach that included extensive interviews and field tests involving 1723 students across five different undergraduate campuses. The GeDI consists of 22 agree–disagree statements that assess four key concepts and six misconceptions. Student scores ranged from 4/22 to 22/22. Statements ranged in mean difficulty from 0.29 to 0.80 and in discrimination from 0.09 to 0.46. The internal consistency, as measured with Cronbach's alpha, ranged from 0.58 to 0.88 across five iterations. Test–retest analysis resulted in a coefficient of stability of 0.82. The true–false format means that the GeDI can test how well students grasp key concepts central to understanding genetic drift, while simultaneously testing for the presence of misconceptions that indicate an incomplete understanding of genetic drift. The insights gained from this testing will, over time, allow us to improve instruction about this key component of evolution. PMID:24591505

Start With What You Know: Using Our Scientific Background in the Classroom

Most "Astro 101” instructors enter their teaching careers as scientists anxious to impart their passion and knowledge of astronomy to the students sitting before them. The reality of the real teaching and learning environment starts when first confronted by non-science majors. Most of these students resist an authentic engagement of learning science and default to the shortest, easiest path to a high grade. Unfortunately this approach is usually unsuccessful in a course designed to measure students’ deep conceptual understanding rather than their declarative knowledge. While it's clear that, by itself, lecturing is insufficient to promote robust or deep learning, it is difficult to create a learning environment that elicits students’ initial ideas on a topic, while confronting and resolving their misconceptions and helping them to resolve their reasoning difficulties. Instructional strategies such as think-pair-share, Lecture-Tutorials, Ranking Tasks, and concept maps can be very successful at elevating students’ intellectual engagement and understanding, even when used in large lecture classrooms. But success will ONLY occur if these strategies are correctly implemented. Mastering the many subtle, and sometimes non-intuitive elements of proper implementation can be so challenging that instructors often abandon an active learning environment and default back to lecture-centered instruction even though they know this results in lower levels of understanding overall. In an effort to improve our teaching, the astronomy faculty of Santiago Canyon College (SCC) have been attending NASA's Center for Astronomy Education Learner-Centered Teaching Excellence workshops. We present our rationale for implementing learner-centered instructional strategies, and the difficulties encountered during implementation. We also present results on how these techniques have promoted meaningful conceptual gains for non-science majors in other equivalent Astro 101 courses. We further report conceptual gains of SCC students, from pre/post testing using the Light, Spectroscopy Concept Inventory, during the 2006-2007 academic school year.

Validation and structural analysis of the kinematics concept test

2017-06-01

The kinematics concept test (KCT) is a multiple-choice test designed to evaluate students' conceptual understanding of kinematics at the high school level. The test comprises 49 multiple-choice items about velocity and acceleration, which are based on seven kinematic concepts and which make use of three different representations. In the first part of this article we describe the development and the validation process of the KCT. We applied the KCT to 338 Swiss high school students who attended traditional teaching in kinematics. We analyzed the response data to provide the psychometric properties of the test. In the second part we present the results of a structural analysis of the test. An exploratory factor analysis of 664 student answers finally uncovered the seven kinematics concepts as factors. However, the analysis revealed a hierarchical structure of concepts. At the higher level, mathematical concepts group together, and then split up into physics concepts at the lower level. Furthermore, students who seem to understand a concept in one representation have difficulties transferring the concept to similar problems in another representation. Both results have implications for teaching kinematics. First, teaching mathematical concepts beforehand might be beneficial for learning kinematics. Second, instructions have to be designed to teach students the change between different representations.

Enhanced learning of proportional math through music training and spatial-temporal training.

PubMed

Graziano, A B; Peterson, M; Shaw, G L

1999-03-01

It was predicted, based on a mathematical model of the cortex, that early music training would enhance spatial-temporal reasoning. We have demonstrated that preschool children given six months of piano keyboard lessons improved dramatically on spatial-temporal reasoning while children in appropriate control groups did not improve. It was then predicted that the enhanced spatial-temporal reasoning from piano keyboard training could lead to enhanced learning of specific math concepts, in particular proportional math, which is notoriously difficult to teach using the usual language-analytic methods. We report here the development of Spatial-Temporal Math Video Game software designed to teach fractions and proportional math, and its strikingly successful use in a study involving 237 second-grade children (age range six years eight months-eight years five months). Furthermore, as predicted, children given piano keyboard training along with the Math Video Game training scored significantly higher on proportional math and fractions than children given a control training along with the Math Video Game. These results were readily measured using the companion Math Video Game Evaluation Program. The training time necessary for children on the Math Video Game is very short, and they rapidly reach a high level of performance. This suggests that, as predicted, we are tapping into fundamental cortical processes of spatial-temporal reasoning. This spatial-temporal approach is easily generalized to teach other math and science concepts in a complementary manner to traditional language-analytic methods, and at a younger age. The neural mechanisms involved in thinking through fractions and proportional math during training with the Math Video Game might be investigated in EEG coherence studies along with priming by specific music.

Assessment of microbiology students' progress with an audience response system.

PubMed

Chaudhry, M Ahmad

2011-01-01

The development of new approaches to teaching of large lecture courses is needed. Today's classroom has a wide range of students including high-achieving motivated learners, students struggling to understand basic concepts, and learning-challenged students. Many of these students can be lost in large classes under the shadow of the high-achieving extroverted students who dominate classroom question-and-answer sessions. Measuring a student's understanding and achievement of content standards becomes difficult until an assessment has been done. To close this gap, an audience response system was introduced in an introductory Principles of Microbiology course.

Motions of Celestial Bodies; Computer simulations

NASA Astrophysics Data System (ADS)

Butikov, Eugene

2014-10-01

This book is written for a wide range of graduate and undergraduate students studying various courses in physics and astronomy. It is accompanied by the award winning educational software package 'Planets and Satellites' developed by the author. This text, together with the interactive software, is intended to help students learn and understand the fundamental concepts and the laws of physics as they apply to the fascinating world of the motions of natural and artificial celestial bodies. The primary aim of the book is the understanding of the foundations of classical and modern physics, while their application to celestial mechanics is used to illustrate these concepts. The simulation programs create vivid and lasting impressions of the investigated phenomena, and provide students and their instructors with a powerful tool which enables them to explore basic concepts that are difficult to study and teach in an abstract conventional manner. Students can work with the text and software at a pace they can enjoy, varying parameters of the simulated systems. Each section of the textbook is supplied with questions, exercises, and problems. Using some of the suggested simulation programs, students have an opportunity to perform interesting mini-research projects in physics and astronomy.

Use of the concept mapping in teaching during a medical rotation of interns: an exploratory study.

PubMed

Kwas, Hamida; Ghédira, Habib

2017-12-01

Concept mapping is an excellent learning toolallowing to stimulate active learning.For this reason, the concept mapping is currently used increasingly in the medical and paramedical field. The aim of our study is to determine the contribution of teaching of medical interns by the concept mapping. Fourteen students enrolled at the same time in a medical rotation in Pulmonology were recruited for this exploratory study. Interns are divided into two groups (A and B).Both groups are taught by the clinical case method, illustrated by a concept mapping for group A interns. The evolution of the knowledge accuracy at post-testing has been greater in the group taught by the method of concept mapping: the number of correct responses increased in all participants of group A versus only 4 of group B. All students taught by concept mapping had at the post-test a note higher than or equal to 10/20 versus only three of the group taught by the method without concept map. The average score was 13 (11-15) in group A versus 10.28 (6-14) in group B. We emphasize the use of concept mapping in teaching especially in the faculty of medicine and we encourage clinicians to use this method in teaching interns in the hospital.

From Biology to Mathematical Models and Back: Teaching Modeling to Biology Students, and Biology to Math and Engineering Students

PubMed Central

McManus, Jeffrey M.; Shaw, Kendrick M.

2010-01-01

We describe the development of a course to teach modeling and mathematical analysis skills to students of biology and to teach biology to students with strong backgrounds in mathematics, physics, or engineering. The two groups of students have different ways of learning material and often have strong negative feelings toward the area of knowledge that they find difficult. To give students a sense of mastery in each area, several complementary approaches are used in the course: 1) a “live” textbook that allows students to explore models and mathematical processes interactively; 2) benchmark problems providing key skills on which students make continuous progress; 3) assignment of students to teams of two throughout the semester; 4) regular one-on-one interactions with instructors throughout the semester; and 5) a term project in which students reconstruct, analyze, extend, and then write in detail about a recently published biological model. Based on student evaluations and comments, an attitude survey, and the quality of the students' term papers, the course has significantly increased the ability and willingness of biology students to use mathematical concepts and modeling tools to understand biological systems, and it has significantly enhanced engineering students' appreciation of biology.

Coteaching with senior students – a way to refine teachers' PCK for teaching chemical bonding in upper secondary school

NASA Astrophysics Data System (ADS)

Schultze, Felix; Nilsson, Pernilla

2018-04-01

During the last decade there has been on-going discussions about students' declining interest and low achievement in science. One of the reasons suggested for this decline is that teachers and students have different frames of reference, whereby teachers sometimes communicate science in the classroom in a way that is not accessible to the students. There is a lack of research investigating the effects of coteaching with senior students in science in upper secondary schools. To improve teaching and to narrow the gap between teachers' and students' different frames of references, this study investigates how an experienced chemistry teacher gains and refines her pedagogical content knowledge (PCK) by cooperating with two grade 12 students (age 18) as coteachers. The teacher and the two coteachers coplanned, cotaught and coevaluated lessons in chemical bonding in a grade 10 upper secondary class. Findings indicate that the coteachers contributed with their own learning experiences to help the teacher understand how students perceive difficult concepts. In such way, the coteachers were mediating between the teacher and the students, thus bridging the gap between the teacher and the students' frames of references. The teachers' PCK was refined which in turn lead to improved teaching strategies.

Activity-Based Introductory Physics Reform *

NASA Astrophysics Data System (ADS)

Thornton, Ronald

2004-05-01

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

Schmitz, Daniela; Höhmann, Ulrike

2016-01-01

Objective: Care for people with dementia is considered a multi-professional challenge that requires a collaborative approach between health professionals and non-health professionals. Didactic strategies to ensure the same qualifications across these occupational groups are lacking. This article presents the joint learning of selected properties and promotive and obstructive conditions, using the example of a multi-professional Master's programme. It subsequently draws conclusions for didactic concepts. Methodology: The perceptions of 12 teachers on this Master's programme, all representing different professions, were determined by using a qualitative exploratory survey on the three stated dimensions. With the aid of a summarising content analysis, their statements were condensed and abstracted so as to deduce appropriate requirements for methodical and didactic learning scenarios. Results: In view of the fact that the students have very varied previous knowledge, the main challenge is finding a balance between expertise and tediousness. Establishing essential and common expertise, as well as sensitivity for different perspectives, is made particularly difficult by the fact that health and non-health professions differ greatly in terms of methods and approaches. For a successful outcome, the content focal points and didactic and methodical concepts for a learning group need to take into account the composition of that specific group. Recourse to didactic standard concepts is only possible to a limited extent. Conclusions: The aim of joint teaching and learning of health and non-health professionals is to enhance the understanding of a profession: This is done by making individuals aware of their role in the chain of care, so they can recognise and organise the mutual conditionality of their own and external professional contributions.

Using Reflective Practice to Facilitate Conversations and Transform Instructional Practice for Middle School Science Teachers

NASA Astrophysics Data System (ADS)

Higdon, Robbie L.

The process of teaching, especially inquiry, is complex and requires extended time for developing one's instructional practice (Loucks-Horsley, Stiles, Mundry, Love, & Hewson, 2010). The implementation of a continued cycle of self-reflection can engage teachers in analyzing their prior experiences and understandings about their instructional practice to promote the accommodation of new concepts and transform their practice. However, many teachers have difficulty engaging in the cognitive dissonance needed to identify those problems and promote their own growth without support. As one's professional practice becomes more repetitive and routine, it is difficult for the practitioner to recognize opportunities in which to contemplate one's habitual actions (Schon, 1983). In this multi-case study, two middle school science teachers who were engaged within a sustained professional development initiative participated in a series of one-on-one reflective dialogues regarding the decisions they made about the utilization of inquiry-based instruction. In addition, these teachers were asked to reflect upon the criteria used to determine how and when to implement these inquiry-based practices. These reflective dialogue sessions provided the opportunity to observe teacher conceptions and stimulate teacher cognitive dissonance about instructional practice. Qualitative analysis of data collected from these reflective dialogues along with informal and formal classroom observations of instructional practice uncovered diverse perceptions regarding the implementation of inquiry-based methods into present teaching practice. The use of reflective dialogue within the existing structure of the professional development initiative allowed for the facilitators of the professional development initiative to tailor ongoing support and their effective implementation of inquiry-based instruction. Additional research is needed to investigate the impact of reflective dialogue in achieving accommodation of new concepts leading to lasting conceptual change about inquiry-based instruction.

Development of an Electrochemistry Teaching Sequence using a Phenomenographic Approach

NASA Astrophysics Data System (ADS)

Rodriguez-Velazquez, Sorangel

Electrochemistry is the area of chemistry that studies electron transfer reactions across an interface. Chemistry education researchers have acknowledged that difficulties in electrochemistry instruction arise due to the level of abstraction of the topic, lack of adequate explanations and representations found in textbooks, and a quantitative emphasis in the application of concepts. Studies have identified conceptions (also referred to as misconceptions, alternative conceptions, etc.) about the electrochemical process that transcends academic and preparation levels (e.g., students and instructors) as well as cultural and educational settings. Furthermore, conceptual understanding of the electrochemical process requires comprehension of concepts usually studied in physics such as electric current, resistance and potential and often neglected in introductory chemistry courses. The lack of understanding of physical concepts leads to students. conceptions with regards to the relation between the concepts of redox reactions and electric circuits. The need for instructional materials to promote conceptual understanding of the electrochemical process motivated the development of the electrochemistry teaching sequence presented in this dissertation. Teaching sequences are educational tools that aim to bridge the gap between student conceptions and the scientific acceptable conceptions that instructors expect students to learn. This teaching sequence explicitly addresses known conceptions in electrochemistry and departs from traditional instruction in electrochemistry to reinforce students. previous knowledge in thermodynamics providing the foundation for the explicit relation of redox reactions and electric circuits during electrochemistry instruction. The scientific foundations of the electrochemical process are explained based on the Gibbs free energy (G) involved rather than on the standard redox potential values (E° ox/red) of redox half-reactions. Representations of the core concepts from discipline-specific models and theories serve as visual tools to describe reversible redox half-reactions at equilibrium, predict the spontaneity of the electrochemical process and explain interfacial equilibrium between redox species and electrodes in solution. The integration of physics concepts into electrochemistry instruction facilitated describing the interactions between the chemical system (e.g., redox species) and the external circuit (e.g., voltmeter). The "Two worlds" theoretical framework was chosen to anchor a robust educational design where the world of objects and events is deliberately connected to the world of theories and models. The core concepts in Marcus theory and density of states (DOS) provided the scientific foundations to connect both worlds. The design of this teaching sequence involved three phases; the selection of the content to be taught, the determination of a coherent and explicit connection among concepts and the development of educational activities to engage students in the learning process. The reduction-oxidation and electrochemistry chapters of three of the most popular general chemistry textbooks were revised in order to identify potential gaps during instruction, taking into consideration learning and teaching difficulties. The electrochemistry curriculum was decomposed into manageable sections contained in modules. Thirteen modules were developed and each module addresses specific conceptions with regard to terminology, redox reactions in electrochemical cells, and the function of the external circuit in electrochemical process. The electrochemistry teaching sequence was evaluated using a phenomenographic approach. This approach allows describing the qualitative variation in instructors' consciousness about the teaching of electrochemistry. A phenomenographic analysis revealed that the most relevant aspect of variation came from instructors' expertise. Participant A expertise (electrochemist) promoted in-depth discussions of fundamental theories and models that explain the electrochemical process while participant B expertise (general chemistry instruction) emphasized a coherent and explicit presentation of such theories and models to students. Other categories of variation were identified as: recognizing students' conceptions, the use of teaching resources and instructors' expectations for the teaching sequence. For example, while Participant B depended heavily on representations and explanations found in textbooks, participant A recognized misleading representations and oversimplified statements in general chemistry textbooks. Participant A was also more inclined to question the significance of some conceptions such as the correlation between the use of the term circuit and students' conceptions related to the movement of electrons in solution in an electrochemical cell. The electrochemistry teaching sequence in this dissertation fulfils each of the instructors' expectations with regards to the content that incorporated discipline-specific theories and models, explicit connections and flow among concepts, and addressing students' conceptions via the educational activities developed.

Wong, Siu Ling; Yung, Benny Hin Wai; Cheng, Man Wai; Lam, Kwok Leung; Hodson, Derek

2006-01-01

This paper reports findings about a curriculum innovation conducted at The University of Hong Kong. A CD-ROM consisting of videos of two lessons by different teachers demonstrating exemplary science teaching was used to elicit conceptions of good science teaching of student-teachers enrolled for the 1-year Postgraduate Diploma in Education at several stages during the programme. It was found that the videos elicited student-teachers’ conceptions and had impact on those conceptions prior to the commencement of formal instruction. It has extended student-teachers’ awareness of alternative teaching methods and approaches not experienced in their own schooling, broadened their awareness of different classroom situations, provided proof of existence of good practices, and prompted them to reflect on their current preconceptions of good science teaching. In several ways, the videos acted as a catalyst in socializing the transition of student-teachers from the role of student to the role of teacher.

Exploring science teachers' pedagogical content knowledge in the teaching of genetics in Swaziland

NASA Astrophysics Data System (ADS)

Mthethwa-Kunene, Khetsiwe Eunice Faith

Recent trends show that learners' enrolment and performance in science at secondary school level is dwindling. Some science topics including genetics in biology are said to be difficult for learners to learn and thus they perform poorly in examinations. Teacher knowledge base, particularly topic-specific pedagogical content knowledge (PCK), has been identified by many researchers as an important factor that is linked with learner understanding and achievement in science. This qualitative study was an attempt to explore the PCK of four successful biology teachers and how they developed it in the context of teaching genetics. The purposive sampling technique was employed to select the participating teachers based on their schools' performance in biology public examinations and recommendations by science specialists and school principals. Pedagogical content knowledge was used as a theoretical framework for the study, which guided the inquiry in data collection, analysis and discussion of the research findings. The study adopted the case study method and various sources of evidence including concept maps, lesson plans, pre-lesson interviews, lesson observations, post-teaching teacher questionnaire, post-lesson interviews and document analysis were used to collect data on teachers' PCK as well as how PCK was assumed to have developed. The data were analysed in an attempt to determine the individual teachers' school genetics' content knowledge, related knowledge of instructional strategies and knowledge of learners' preconceptions and learning difficulties. The analysis involved an iterative process of coding data into PCK categories of content knowledge, pedagogical knowledge and knowledge of learners' preconceptions and learning difficulties. The findings of the study indicate that the four successful biology teachers generally have the necessary content knowledge of school genetics, used certain topic-specific instructional strategies, but lacked knowledge of genetics-related learners' preconceptions and learning difficulties despite having taught the topic for many years. There were some instructional deficits in their approaches and techniques in teaching genetics. The teachers failed to use physical models, teacher demonstration and/or learner experimentation in their lessons (or include them in their lesson plans) to assist learners in visualizing or internalizing the genetics concepts or processes located at the sub-microscopic level. The teachers' PCK in genetics teaching was assumed to have developed mainly through formal university education programmes, classroom teaching experiences, peer support and participation in in-service workshops. The implications for biology teacher education are also discussed.

E-learning: Web-based education.

Sajeva, Marco

2006-12-01

This review introduces state-of-the-art Web-based education and shows how the e-learning model can be applied to an anaesthesia department using Open Source solutions, as well as lifelong learning programs, which is happening in several European research projects. The definition of the term e-learning is still a work in progress due to the fact that technologies are evolving every day and it is difficult to improve teaching methodologies or to adapt traditional methods to a new or already existing educational model. The European Community is funding several research projects to define the new common market place for tomorrow's educational system; this is leading to new frontiers like virtual Erasmus inter-exchange programs based on e-learning. The first step when adapting a course to e-learning is to re-define the educational/learning model adopted: cooperative learning and tutoring are the two key concepts. This means that traditional lecture notes, books and exercises are no longer effective; teaching files must use rich multimedia content and have to be developed using the new media. This can lead to several pitfalls that can be avoided with an accurate design phase.

Understanding ‘human’ waves: exploiting the physics in a viral video

NASA Astrophysics Data System (ADS)

Ferrer-Roca, Chantal

2018-01-01

Waves are a relevant part of physics that students find difficult to grasp, even in those cases in which wave propagation kinematics can be visualized. This may hinder a proper understanding of sound, light or quantum physics phenomena that are explained using a wave model. So-called ‘human’ waves, choreographed by people, have proved to be an advisable way to understand basic wave concepts. Videos are widely used as a teaching resource and can be of considerable help in order to watch and discuss ‘human’ waves provided their quality is reasonably good. In this paper we propose and analyse a video that went viral online and has been revealed to be a useful teaching resource for introductory physics students. It shows a unique and very complete series of wave propagations, including pulses with different polarizations and periodic waves that can hardly be found elsewhere. After a proposal on how to discuss the video qualitatively, a quantitative analysis is carried out (no video-tracker needed), including a determination of the main wave magnitudes such as period, wavelength and propagation speed.

The affordances of using a flipped classroom approach in the teaching of mathematics: a case study of a grade 10 mathematics class

NASA Astrophysics Data System (ADS)

Muir, Tracey; Geiger, Vince

2016-03-01

Teaching secondary mathematics has a number of challenges, including the expectations that teachers cover the prescribed curriculum, help students learn difficult concepts, prepare students for future studies, and, increasingly, that they do so incorporating digital technologies. This study investigates a teacher's, and his students', perceptions of the benefits or otherwise of a flipped classroom approach in meeting these challenges, within a prescribed curriculum context. Data collection instruments included a survey designed to investigate the nature of students' engagement with the flipped approach and semi-structured student and teacher interviews. Analysis of these data indicated that the teacher and students were positive about their experiences with a flipped classroom approach and that students were motivated to engage with the teacher-created online mathematics resources. The study adds to the limited research literature related to student and teacher perceptions of the affordances of the flipped classroom approach and has implications for secondary mathematics teachers who face the challenge of the twin demands of covering the prescribed curriculum and catering for a range of students' learning needs.

Teaching about Water Relations in Plant Cells: An Uneasy Struggle

PubMed Central

Malińska, Lilianna; Rybska, Eliza; Sobieszczuk-Nowicka, Ewa; Adamiec, Małgorzata

2016-01-01

University students often struggle to understand the role of water in plant cells. In particular, osmosis and plasmolysis appear to be challenging topics. This study attempted to identify student difficulties (including misconceptions) concerning osmosis and plasmolysis and examined to what extent the difficulties could be revised during a plant physiology course. A questionnaire was developed to monitor university students’ conceptual knowledge before and after a course, and both qualitative and quantitative data were obtained. The data were analyzed using the constant comparison technique and descriptive statistics. Students were found to come to university with many misconceptions that had accumulated during their education. These misconceptions are extremely difficult to change during the traditional course, which comprises lectures and practical exercises. Students’ misconceptions originate from commonly used sources such as textbooks, which are perceived as being reliable. Effective teaching of water relations in plant cells could include such didactic methods as “questioning the author,” which allow teachers to monitor students’ knowledge and help students acquire a more scientific understanding of key concepts.

Necessity and Contention of Education on Engineer Ethics

NASA Astrophysics Data System (ADS)

Takeda, Kunihiko; Ishikawa, Tomoyuki

Using examples of major accidents caused by technical technology are effective when teaching engineering ethics in undergraduate courses because almost all students have had no actual experience in technical problems or accidents in their lives. The typical accidents that have been selected in the past for this purpose by lecturers are limited in Japanese colleges or in textbooks. Some examples are the Minamata disease, the Kanemi oil PCB contamination, the space shuttle “Challenger” accident, the Ford “Pinto” design problem, Mitsubishi Motor's scandal and the unclear power plant accident at Tokai. However, it is difficult to decide whether or not these typical accidents are suitable for the teaching of engineering ethics. The responsibility of an engineer in Japan is strictly limited because he has no authority to finally decide upon the problem of ethics even if the item is purely technical and he is the best person to make the decision. The reason is discussed focusing on 1) the concept of the “profession” of medical doctors and engineers and 2) the relationships between the treatment, position, honor and responsibility of engineers in Japanese society.

Changing to Concept-Based Curricula: The Process for Nurse Educators.

PubMed

Baron, Kristy A

2017-01-01

The complexity of health care today requires nursing graduates to use effective thinking skills. Many nursing programs are revising curricula to include concept-based learning that encourages problem-solving, effective thinking, and the ability to transfer knowledge to a variety of situations-requiring nurse educators to modify their teaching styles and methods to promote student-centered learning. Changing from teacher-centered learning to student-centered learning requires a major shift in thinking and application. The focus of this qualitative study was to understand the process of changing to concept-based curricula for nurse educators who previously taught in traditional curriculum designs. The sample included eight educators from two institutions in one Western state using a grounded theory design. The themes that emerged from participants' experiences consisted of the overarching concept, support for change, and central concept, finding meaning in the change. Finding meaning is supported by three main themes : preparing for the change, teaching in a concept-based curriculum, and understanding the teaching-learning process. Changing to a concept-based curriculum required a major shift in thinking and application. Through support, educators discovered meaning to make the change by constructing authentic learning opportunities that mirrored practice, refining the change process, and reinforcing benefits of teaching.

Adili, F; Kadmon, M; König, S; Walcher, F

2013-10-01

For competency-oriented teaching in surgery a comprehensive medical educational training and professionalization of clinical teachers is essential. The Surgical Working Group for Teaching has therefore set itself the task of developing an appropriate training concept. In the first step the core group took stock of the most relevant educational barriers in the clinical environment. Taking into account these findings a trimodular course was devised that addressed both previous knowledge and different clinical functions of the faculty as well as modern concepts of competency-based academic teaching. The A course is designed for medical teaching of novices with a focus on collation of the medical history, clinical examination and teaching of practical skills. The B course is devised for experienced clinicians and should qualify them for competency-based teaching in complex educational scenarios, such as the operating room or ward rounds, while the C course is directed to a group of persons entrusted with the organization and administration of clinical teaching.

Preservice elementary teachers' alternative conceptions of science and their self-efficacy beliefs about science teaching

NASA Astrophysics Data System (ADS)

Koc, Isil

The present study was conducted to investigate the extent to which preservice elementary teachers held alternative conceptions in fundamental elementary science concepts from earth/space science, life science, and physical science along with their self-efficacy beliefs about science teaching and to determine the relationship between these two issues. Eighty-six preservice elementary education majors enrolled in the four sections of the course titled "07E:162 Methods Elementary School Science" offered in the Science Education Center, College of Education, the University of Iowa during the 2005-2006 academic year participated in this study. Twelve preservice elementary teachers participated in follow-up interviews. Data were collected through the use of Alternative Conceptions in Science Instrument constructed by Schoon and Boone (1998), Science Teaching Efficacy Belief Instrument (STEBI-B) constructed by Enochs and Riggs (1990), a participant information form, and through utilization of interviews. The results from the alternative conception instrument indicated that the majority of preservice elementary teachers held a number of alternative conceptions with most being in the physical sciences followed by earth/space, and then life science. Various sources of alternative conceptions emerged during the interview sessions. Participants mainly cited science teachers, science textbooks, and previous science experiences as sources of their alternative conceptions. On the other hand, the analysis of the self-efficacy instrument and follow-up interviews revealed generally positive self-efficacy beliefs. Findings from the study also confirmed that science courses completed in high school and college do not seem to have influenced participants' number and types of alternative conceptions regarding earth/space science, life science, and physical science and self-efficacy beliefs about science teaching. The results also indicate that participants with the lowest number of alternative conceptions regarding earth/space science, physical science, and life science have a relatively high personal science teaching efficacy. Overall, the results of the study regarding self-efficacy beliefs propose that consideration be given to identification and modification of preservice elementary teachers' science alternative conceptions if they are expected to teach science effectively.

The evolution of teaching.

PubMed

Fogarty, L; Strimling, P; Laland, K N

2011-10-01

Teaching, alongside imitation, is widely thought to underlie the success of humanity by allowing high-fidelity transmission of information, skills, and technology between individuals, facilitating both cumulative knowledge gain and normative culture. Yet, it remains a mystery why teaching should be widespread in human societies but extremely rare in other animals. We explore the evolution of teaching using simple genetic models in which a single tutor transmits adaptive information to a related pupil at a cost. Teaching is expected to evolve where its costs are outweighed by the inclusive fitness benefits that result from the tutor's relatives being more likely to acquire the valuable information. We find that teaching is not favored where the pupil can easily acquire the information on its own, or through copying others, or for difficult to learn traits, where teachers typically do not possess the information to pass on to relatives. This leads to a narrow range of traits for which teaching would be efficacious, which helps to explain the rarity of teaching in nature, its unusual distribution, and its highly specific nature. Further models that allow for cumulative cultural knowledge gain suggest that teaching evolved in humans because cumulative culture renders otherwise difficult-to-acquire valuable information available to teach. © 2011 The Author(s).

Medical curricula are currently being reformed in order to establish superordinated learning objectives, including, e.g., diagnostic, therapeutic and preventive competences. This requires a shifting from traditional teaching methods towards interactive and case-based teaching concepts. Conceptions, initial experiences and student evaluations of a novel radiological course Co-operative Learning In Clinical Radiology (CLICR) are presented in this article. A novel radiological teaching course (CLICR course), which combines different innovative teaching elements, was established and integrated into the medical curriculum. Radiological case vignettes were created for three clinical teaching modules. By using a PC with PACS (Picture Archiving and Communication System) access, web-based databases and the CASUS platform, a problem-oriented, case-based and independent way of learning was supported as an adjunct to the well established radiological courses and lectures. Student evaluations of the novel CLICR course and the radiological block course were compared. Student evaluations of the novel CLICR course were significantly better compared to the conventional radiological block course. Of the participating students 52% gave the highest rating for the novel CLICR course concerning the endpoint overall satisfaction as compared to 3% of students for the conventional block course. The innovative interactive concept of the course and the opportunity to use a web-based database were favorably accepted by the students. Of the students 95% rated the novel course concept as a substantial gain for the medical curriculum and 95% also commented that interactive working with the PACS and a web-based database (82%) promoted learning and understanding. Interactive, case-based teaching concepts such as the presented CLICR course are considered by both students and teachers as useful extensions to the radiological course program. These concepts fit well into competence-oriented curricula.

Concept mapping is an effective method in teaching and learning, however this strategy has not been evaluated among electrocardiogram (ECG) diagnosis learning. This study explored the use of concept maps to assist ECG study, and sought to analyze whether this method could improve undergraduate students’ ECG interpretation skills. There were 126 undergraduate medical students who were randomly selected and assigned to two groups, group A (n = 63) and group B (n = 63). Group A was taught to use concept maps to learn ECG diagnosis, while group B was taught by traditional methods. After the course, all of the students were assessed by having an ECG diagnostic test. Quantitative data which comprised test score and ECG features completion index was compared by using the unpaired Student’s t-test between the two groups. Further, a feedback questionnaire on concept maps used was also completed by group A, comments were evaluated by a five-point Likert scale. The test scores of ECGs interpretation was 7.36 ± 1.23 in Group A and 6.12 ± 1.39 in Group B. A significant advantage (P = 0.018) of concept maps was observed in ECG interpretation accuracy. No difference in the average ECG features completion index was observed between Group A (66.75 ± 15.35%) and Group B (62.93 ± 13.17%). According qualitative analysis, majority of students accepted concept maps as a helpful tool. Difficult to learn at the beginning and time consuming are the two problems in using this method, nevertheless most of the students indicated to continue using it. Concept maps could be a useful pedagogical tool in enhancing undergraduate medical students’ ECG interpretation skills. Furthermore, students indicated a positive attitude to it, and perceived it as a resource for learning. PMID:26221331

Is physics worth teaching?

NASA Astrophysics Data System (ADS)

Machold, Dolf K.

1992-09-01

The paper points out that many students and adults are accustomed to solving problems in physics on the basis of everyday concepts; believing that these concepts are very successful, those students are not interested in concepts offered by science teaching. Furthermore, the teaching physics in terms of mathematical descriptions of problems is too early — students don't see the original problem, so they are not interested in solutions. One way to avoid these difficulties is M. Wagenschein's proposal of the ‘Exemplary-genetic Method’. This method and its principles are presented and illustrated with examples taken from history. On the basis of this method educational and pedagogical functions of teaching physics are developed. P.S.: Martin Wagenschein (1896 1989), Professor of physics education at the University of Tübingen, was concerned with finding new methods for successfully teaching science.

Teaching tools in Evidence Based Practice: evaluation of reusable learning objects (RLOs) for learning about Meta-analysis

PubMed Central

2011-01-01

Background All healthcare students are taught the principles of evidence based practice on their courses. The ability to understand the procedures used in systematically reviewing evidence reported in studies, such as meta-analysis, are an important element of evidence based practice. Meta-analysis is a difficult statistical concept for healthcare students to understand yet it is an important technique used in systematic reviews to pool data from studies to look at combined effectiveness of treatments. In other areas of the healthcare curricula, by supplementing lectures, workbooks and workshops with pedagogically designed, multimedia learning objects (known as reusable learning objects or RLOs) we have shown an improvement in students' perceived understanding in subjects they found difficult. In this study we describe the development and evaluation of two RLOs on meta-analysis. The RLOs supplement associated lectures and aim to improve students' understanding of meta-analysis in healthcare students. Methods Following a quality controlled design process two RLOs were developed and delivered to two cohorts of students, a Master in Public Health course and Postgraduate diploma in nursing course. Students' understanding of five key concepts of Meta-analysis were measured before and after a lecture and again after RLO use. RLOs were also evaluated for their educational value, learning support, media attributes and usability using closed and open questions. Results Students rated their understanding of meta-analysis as improved after a lecture and further improved after completing the RLOs (Wilcoxon paired test, p < 0.01 in all cases) Whilst the media components of the RLOs such as animations helped most students (86%) understand concepts including for example Forest plots, 93% of students rated usability and control as important to their learning. A small number of students stated they needed the support of a lecturer alongside the RLOs (7% 'Agreed' and 21% 'Neutral'). Conclusions Meta-analysis RLOs that are openly accessible and unrestricted by usernames and passwords provide flexible support for students who find the process of meta-analysis difficult.

This research-in-progress hypothesizes that urban second graders can have an early understanding about the shape of Sun, Moon, and Earth, how day and night happens, and how Moon appears to change its shape by using three dimensional stereoscopic vision. The 3D stereoscopic vision system might be an effective way to teach subjects like astronomy that explains relationships among objects in space. Currently, Indiana state standards for science teaching do not suggest the teaching of these astronomical concepts explicitly before fourth grade. Yet, we expect our findings to indicate that students can learn these concepts earlier in their educational lives with the implementation of such technologies. We also project that these technologies could revolutionize when these concepts could be taught to children and expand the ways we think about children's cognitive capacities in understanding scientific concepts.

kNOw Soil - kNOw Life: Integrating soil science across disciplines

Teaching primary and secondary school students (K-12) about science and art, although absolutely critical, can be difficult. Teachers have specific standards or subject matters that they are required to cover and often soils and soil science is not included in that list. We have struggled with ways to bring soil science information to the larger audience as the direct approach meets with resistance due to the time commitments to other standards. Our approach now is to use soils as a media or vehicle to teach key concepts in broad subject areas. We have developed several lesson plans in science, geography, math and art that focus on a concept but use soils to convey it. For example students make "mini" monoliths of a state soil. During this exercise students need to use skills in geography to find where their state soil occurs in their state and in the country. They need to understand colors in order to choose the correct colors to use to make their monolith. Finally, they must understand how scales work in order to make the monolith accurate in terms of horizon depths. Throughout the exercise discussion on my certain colors occur in the soil can be discussed. This discussion can lead to a qualitative understanding of chemistry and biology. This presentation will demonstrate this lesson and several others that have been developed and available through the Soil Science Society of America's K12 Education Committee and our International Year of Soil website.

Advancing clinical reasoning in virtual patients - development and application of a conceptual framework.

Background: Clinical reasoning is a complex skill students have to acquire during their education. For educators it is difficult to explain their reasoning to students, because it is partly an automatic and unconscious process. Virtual Patients (VPs) are used to support the acquisition of clinical reasoning skills in healthcare education. However, until now it remains unclear which features or settings of VPs optimally foster clinical reasoning. Therefore, our aims were to identify key concepts of the clinical reasoning process in a qualitative approach and draw conclusions on how each concept can be enhanced to advance the learning of clinical reasoning with virtual patients. Methods: We chose a grounded theory approach to identify key categories and concepts of learning clinical reasoning and develop a framework. Throughout this process, the emerging codes were discussed with a panel of interdisciplinary experts. In a second step we applied the framework to virtual patients. Results: Based on the data we identified the core category as the "multifactorial nature of learning clinical reasoning". This category is reflected in the following five main categories: Psychological Theories, Patient-centeredness, Context, Learner-centeredness, and Teaching/Assessment. Each category encompasses between four and six related concepts. Conclusions: With our approach we were able to elaborate how key categories and concepts of clinical reasoning can be applied to virtual patients. This includes aspects such as allowing learners to access a large number of VPs with adaptable levels of complexity and feedback or emphasizing dual processing, errors, and uncertainty.

Conceptually driven and visually rich tasks in texts and teaching practice: the case of infinite series

González-Martín, Alejandro S.; Nardi, Elena; Biza, Irene

2011-07-01

The study we report here examines parts of what Chevallard calls the institutional dimension of the students' learning experience of a relatively under-researched, yet crucial, concept in Analysis, the concept of infinite series. In particular, we examine how the concept is introduced to students in texts and in teaching practice. To this purpose, we employ Duval's Theory of Registers of Semiotic Representation towards the analysis of 22 texts used in Canada and UK post-compulsory courses. We also draw on interviews with in-service teachers and university lecturers in order to discuss briefly teaching practice and some of their teaching suggestions. Our analysis of the texts highlights that the presentation of the concept is largely a-historical, with few graphical representations, few opportunities to work across different registers (algebraic, graphical, verbal), few applications or intra-mathematical references to the concept's significance and few conceptually driven tasks that go beyond practising with the application of convergence tests and prepare students for the complex topics in which the concept of series is implicated. Our preliminary analysis of the teacher interviews suggests that pedagogical practice often reflects the tendencies in the texts. Furthermore, the interviews with the university lecturers point at the pedagogical potential of: illustrative examples and evocative visual representations in teaching; and, student engagement with systematic guesswork and writing explanatory accounts of their choices and applications of convergence tests.

Teaching to Promote Deep Understanding and Instigate Conceptual Change

Zirbel, Esther

2006-12-01

This paper focuses on how to promote deep understanding by making the students to question their inherent conceptual knowledge of how the world works, and on how to correct these views should they be different form the scientifically proven views. This paper reviews the conceptual change model and suggests additional steps. First, the student has to consciously notice and understand what the problem is; second, s/he has to assimilate more information and try to fit it into already existing neural networks; third, s/he has to critically think through all the argumentation in his/her own words and reorganize this thoughts s/he has to accommodate the knowledge and evaluate against his or her prior beliefs; forth s/he has to own the concept and has to consider it her/his personal construct; and finally, s/he has to work towards obtaining fluency in the newly acquired and understood concept so that this concept itself has then becomes a mere building block for future, more advanced concepts. The claim is that during the process of conceptual change what happens in the student’s mind is a reorganization of his or her thoughts, the creation of new neural networks, and the rewiring of old ones. This process is difficult to provoke and requires the student to work hard. Instructors can challenge the student to undergo the process of conceptual change but cannot do it for the student.

Clinical training imposes time and resource constraints on educators and learners, making it difficult to provide and absorb meaningful instruction. Additionally, innovative and personalized education has become an expectation of adult learners. Fortunately, the development of web-based educational tools provides a possible solution to these challenges. Within this review, we introduce the utility of adaptive eLearning platforms in pathology education. In addition to a review of the current literature, we provide the reader with a suggested approach for module creation, as well as a critical assessment of an available platform, based on our experience in creating adaptive eLearning modules for teaching basic concepts in gynecologic cytopathology.

Assessment of Microbiology Students’ Progress With an Audience Response System

PubMed Central

Chaudhry, M. Ahmad

2011-01-01

The development of new approaches to teaching of large lecture courses is needed. Today’s classroom has a wide range of students including high-achieving motivated learners, students struggling to understand basic concepts, and learning-challenged students. Many of these students can be lost in large classes under the shadow of the high-achieving extroverted students who dominate classroom question-and-answer sessions. Measuring a student’s understanding and achievement of content standards becomes difficult until an assessment has been done. To close this gap, an audience response system was introduced in an introductory Principles of Microbiology course. This technology specifically addressed the goal of individualizing instruction to the needs of the students. The evaluation of this project indicated an overall positive impact on student learning.

2010-02-01

This paper reports on an investigation of the effectiveness an intervention using several different methods for teaching solution chemistry. The teaching strategy comprised a four-step approach derived from a constructivist view of learning. A sample consisting of 44 students (18 boys and 26 girls) was selected purposively from two different Grade 9 classes in the city of Trabzon, Turkey. Data collection employed a purpose-designed `solution chemistry concept test', consisting of 17 items, with the quantitative data from the survey supported by qualitative interview data. The findings suggest that using different methods embedded within the four-step constructivist-based teaching strategy enables students to refute some alternative conceptions, but does not completely eliminate student alternative conceptions for solution chemistry.

Changing to Concept-Based Curricula: The Process for Nurse Educators

Baron, Kristy A.

2017-01-01

Background: The complexity of health care today requires nursing graduates to use effective thinking skills. Many nursing programs are revising curricula to include concept-based learning that encourages problem-solving, effective thinking, and the ability to transfer knowledge to a variety of situations—requiring nurse educators to modify their teaching styles and methods to promote student-centered learning. Changing from teacher-centered learning to student-centered learning requires a major shift in thinking and application. Objective: The focus of this qualitative study was to understand the process of changing to concept-based curricula for nurse educators who previously taught in traditional curriculum designs. Methods: The sample included eight educators from two institutions in one Western state using a grounded theory design. Results: The themes that emerged from participants’ experiences consisted of the overarching concept, support for change, and central concept, finding meaning in the change. Finding meaning is supported by three main themes: preparing for the change, teaching in a concept-based curriculum, and understanding the teaching-learning process. Conclusion: Changing to a concept-based curriculum required a major shift in thinking and application. Through support, educators discovered meaning to make the change by constructing authentic learning opportunities that mirrored practice, refining the change process, and reinforcing benefits of teaching.

Biosciences in nurse education: is the curriculum fit for practice? Lecturers' views and recommendations from across the UK.

Taylor, Vanessa; Ashelford, Sarah; Fell, Patricia; Goacher, Penelope J

2015-10-01

This study aims to review the biosciences component of preregistration nursing programmes in higher education institutions across the UK through the experiences and perceptions of lecturers involved in nursing education. Studies suggest that some qualified nurses lack confidence in explaining the bio-scientific rationale for their clinical practice. Biosciences can be difficult to understand and integrate into clinical decision-making and require protected time within preregistration nurse education. In the absence of explicit national guidelines, it is unclear as to the depth and extent biosciences are taught across different institutions and the level achieved at the point of registration. A survey approach was adopted to generate quantitative and qualitative feedback. Data were collected using a semi-structured questionnaire seeking the experiences and views of lecturers involved in teaching biosciences to nursing students across the UK. Data received from 10 institutions were analysed using descriptive statistics and thematic analysis. Lecturers reported that the hours of taught biosciences ranged from 20-113 hours, principally within the first year. This represents between 0·4-2·4% of time within a preregistration nursing programme (4600 hours). Large group lectures predominate, supplemented by smaller group or practical work, and online materials. The biosciences are assessed specifically in half the institutions surveyed and as part of integrated assessments in the rest. In relation to student feedback, all respondents stated that students consistently requested more time and greater priority for biosciences in their programme. This survey suggests that the number of hours spent teaching biosciences is minimal and varies widely between higher education institutions. All respondents expressed concern about the challenges of teaching difficult bio-scientific concepts to large groups in such a limited time and called for greater clarity in national guidelines to ensure that all nurses are adequately educated and assessed in bioscience subjects. Failure to understand the biosciences underpinning care has implications for safe and competent nursing. © 2015 John Wiley & Sons Ltd.

Development of a Solar System Concept Inventory

NASA Astrophysics Data System (ADS)

Hornstein, Seth D.; Duncan, D.; S, C. A. T.

2009-01-01

Concept inventories can provide useful insight into students’ understanding of key physical concepts. Knowing what your students have learned during a course is a valuable tool for improving your own teaching. Unfortunately, current astronomy concept inventories are not suitable for an introductory solar system course because they either cover too broad of a range of topics (e.g. Astronomy Diagnostic Test) or are too narrowly focused (e.g. Greenhouse Effect Concept Inventory, Lunar Phase Concept Inventory). We have developed the Solar System Concept Inventory (SSCI) to cover those topics commonly taught in an introductory solar system course. The topics included on the SSCI were selected by having faculty identify the key concepts they address when teaching about the solar system. SSCI topics include formation mechanisms, planetary interiors, atmospheric effects, and small solar system bodies. Student interviews were conducted to identify common naive ideas and reasoning difficulties relating to these key topics. Preliminary development of the SSCI was completed at the University of Colorado and involved over 400 students. A larger, national, multi-institutional field test is planned for Spring 2009 as a Collaboration of Astronomy Teaching Scholars (CATS) research project. We present here the results from the preliminary development and proposed changes for the next stage of research. We would like to thank the NSF for funding under Grant No. 0715517, a CCLI Phase III Grant for the Collaboration of Astronomy Teaching Scholars (CATS) Program.

Development of Problem-Based Learning Oriented Teaching Learning Materials to Facilitate Students’ Mastery of Concept and Critical Thinking Skill

2018-01-01

This research aims to develop problem-based learning oriented teaching materials to improve students’ mastery of concept and critical thinking skill. Its procedure was divided into two phases; developmental phase and experimental phase. This developmental research used Four-D Model. However, within this research, the process of development would not involve the last stages, which is disseminate. The teaching learning materials which were developed consist of lesson plan, student handbook, student worksheet, achievement test and critical thinking skill test. The experimental phase employs a research design called one group pretest-posttest design. Results show that the validity of the teaching materials which were developed was good and revealed the enhancement of students’ activities with positive response to the teaching learning process. Furthermore, the learning materials improve the students’ mastery of concept and critical thinking skill.

Pancreatic trauma: Universities of Melbourne HPB Group.

PubMed

Fleming, W R; Collier, N A; Banting, S W

1999-05-01

Pancreatic trauma is uncommon, but carries high morbidity and mortality rates, especially when diagnosis is delayed or inappropriate surgery is attempted. Although the retroperitoneal position of the pancreas confers it some immunity to injury, the force required to do so often results in severe associated injuries to other organs, which may be life threatening. Diagnosis may be difficult and surgery can be a considerable technical challenge. All patients with pancreatic trauma who attended one of three Melbourne teaching hospitals from 1977 to 1998 were identified. Injuries were graded and the method of diagnosis and treatment studied. The incidence and causation of postoperative morbidity and mortality was identified. Thirty-eight patients (26 men and 12 women) were studied. Blunt trauma was responsible in 30 patients, stab wounds in five, gunshot wounds in two and iatrogenic injury in one. Injuries to other organs occurred in 30 patients. Surgical procedures were undertaken in 34 patients, resulting in the death of five and complications in 25. Complications and death are related to the associated injuries, as much as to the pancreatic injury itself. In this study, we review the experience of the management of pancreatic trauma in three large teaching hospitals in Melbourne over a 21-year period, and suggest a strategy for dealing with these difficult patients. Adherence to the basic concepts of control of bleeding from associated vascular injury, minimization of contamination, accurate pancreatic assessment, judicious resection and adequate drainage can diminish the risk. By approaching the problem in a systematic way and adopting a generally conservative management plan, complications and deaths can be minimized in these complex cases.

Teaching undergraduate biomechanics with Just-in-Time Teaching.

Riskowski, Jody L

2015-06-01

Biomechanics education is a vital component of kinesiology, sports medicine, and physical education, as well as for many biomedical engineering and bioengineering undergraduate programmes. Little research exists regarding effective teaching strategies for biomechanics. However, prior work suggests that student learning in undergraduate physics courses has been aided by using the Just-in-Time Teaching (JiTT). As physics understanding plays a role in biomechanics understanding, the purpose of study was to evaluate the use of a JiTT framework in an undergraduate biomechanics course. This two-year action-based research study evaluated three JiTT frameworks: (1) no JiTT; (2) mathematics-based JiTT; and (3) concept-based JiTT. A pre- and post-course assessment of student learning used the biomechanics concept inventory and a biomechanics concept map. A general linear model assessed differences between the course assessments by JiTT framework in order to evaluate learning and teaching effectiveness. The results indicated significantly higher learning gains and better conceptual understanding in a concept-based JiTT course, relative to a mathematics-based JiTT or no JiTT course structure. These results suggest that a course structure involving concept-based questions using a JiTT strategy may be an effective method for engaging undergraduate students and promoting learning in biomechanics courses.

Are Danish doctors comfortable teaching in English?

2016-08-27

From 2012-2015, the Departments of Obstetrics and Gynecology and of Pediatrics at the University of Copenhagen conducted a project, "Internationalization at Home ", offering clinical teaching in English. The project allowed international students to work with Danish speaking students in a clinical setting. Using semi-quantitative questionnaires to 89 clinicians about use of English and need for training, this paper considers if Danish clinical doctors are prepared to teach in English. The majority self-assessed their English proficiency between seven and eight on a 10 unit visual analogue scale, with 10 equivalent to working in Danish, while 15 % rated five or less. However, one-fourth found teaching and writing in English to be twice as difficult than in Danish, and 12 % rated all teaching tasks in English at four or less compared to Danish. The self-assessed need for additional English skills was perceived low. Teaching in English was rated as 30 % more difficult than in Danish, and a significant subgroup of doctors had difficulties in all forms of communication in English, resulting in challenges when introducing international students in non-native English speaking medical departments.

3D animation model with augmented reality for natural science learning in elementary school

Many opinions from primary school students' on Natural Science are a difficult lesson. Many subjects are not easily understood by students, especially on materials that teach some theories about natural processes. Such as rain process, condensation and many other processes. The difficulty that students experience in understanding it is that students cannot imagine the things that have been taught in the material. Although there is material to practice some theories but is actually quite limited. There is also a video or simulation material in the form of 2D animated images. Understanding concepts in natural science lessons are also poorly understood by students. Natural Science learning media uses 3-dimensional animation models (3D) with augmented reality technology, which offers some visualization of science lessons. This application was created to visualize a process in Natural Science subject matter. The hope of making this application is to improve student's concept. This app is made to run on a personal computer that comes with a webcam with augmented reality. The app will display a 3D animation if the camera can recognize the marker.

[Historic, cultural, legal, psychosocial and educational aspects of induced abortion].

PubMed

Aguirre Zozaya, F; Iglesias, M; Reyes, R M; Iturralde, G; Martínez, M; Pineda Hernández, C

1980-08-01

The history of abortion is a very long one. Every people and nation used different and widely varied methods during the centuries to get rid of unwanted pregnancies. Unfortunately, in most instances, the great majority of these methods was equivalent to zero effectiveness, or, too often, to suicide. Legal aspects of induced abortion have changed considerably with the passing of time and according to countries; these days 36% of the world countries admit abortion on request, 24% for specific reasons only, 16% for medical reasons only, and 8% still consider it an illegal practice. In Mexico abortion is legal only when pregnancy would imply death of the mother, when it is the result of rape of minors, or when it is done on women with very serious mental pathology. Obviously abortion is not the solution to unwanted pregnancies; an improvement in the socioeconomic condition and in the quality of life of many people would be a much better, and more difficult, approach to the solution. Psychosocial factors of abortion involve concepts which are difficult to define, such as those of the wanted or of the unwanted child, and can cause problems which are very difficult to handle. Health education, and sex education in particular, should not only teach the fundamentals of reproduction, but respect and consideration for the phenomenon of procreation, and a strong sense of personal and social responsibility toward family planning.

2018-01-01

Problem-based learning (PBL) as a teaching strategy has recently become quite widespread in especially chemistry classes. Research has found that students, from elementary through college, have many alternative conceptions regarding enthalpy changes in systems. Although there are several studies focused on identifying student alternative conceptions and misunderstandings of this subject, studies on preventing the formation of these alternative conceptions are limited.

A Teaching Model for Scaffolding 4th Grade Students' Scientific Explanation Writing

NASA Astrophysics Data System (ADS)

Yang, Hsiu-Ting; Wang, Kuo-Hua

2014-08-01

Improving students scientific explanations is one major goal of science education. Both writing activities and concept mapping are reported as effective strategies for enhancing student learning of science. The purpose of this study was to examine the effect of a teaching model, named the DCI model, which integrates a Descriptive explanation writing activity, Concept mapping, and an Interpretive explanation writing activity, is introduced in a 4th grade science class to see if it would improve students' scientific explanations and understanding. A quasi-experimental design, including a non-randomized comparison group and a pre- and post-test design, was adopted for this study. An experimental group of 25 students were taught using the DCI teaching model, while a comparison group received a traditional lecture teaching. A rubric and content analysis was used to assess students' scientific explanations. The independent sample t test was used to measure difference in conceptual understanding between the two groups, before and after instruction. Then, the paired t test analysis was used to understand the promotion of the DCI teaching model. The results showed that students in the experimental group performed better than students in the comparison group, both in scientific concept understanding and explanation. Suggestions for using concept mapping and writing activities (the DCI teaching model) in science classes are provided in this study.

Open inquiry-based learning experiences: a case study in the context of energy exchange by thermal radiation

NASA Astrophysics Data System (ADS)

Pizzolato, Nicola; Fazio, Claudio; Rosario Battaglia, Onofrio

2014-01-01

An open inquiry (OI)-based teaching/learning experience, regarding a scientific investigation of the process of energy exchange by thermal radiation, is presented. A sample of upper secondary school physics teachers carried out this experience at the University of Palermo, Italy, in the framework of ESTABLISH, a FP7 European Project aimed at promoting and developing inquiry-based science education. The teachers had the opportunity to personally experience an OI-based learning activity, with the aim of exploring the pedagogical potentialities of this teaching approach to promote both the understanding of difficult concepts and a deeper view of scientific practices. The teachers were firstly engaged in discussions concerning real-life problematic situations, and then stimulated to design and carry out their own laboratory activities, aimed at investigating the process of energy exchange by thermal radiation. A scientific study on the energy exchange between a powered resistor and its surrounding environment, during the heating and cooling processes, was designed and performed. Here we report the phases of this experiment by following the teachers' perspective. A structured interview conducted both before and after the OI experience allowed us to analyze and point out the teachers' feedback from a pedagogical point of view. The advantages and limits of an OI-based approach to promote the development of more student-centred inquiry-oriented teaching strategies are finally discussed.

Biology laboratory classes are designed to teach concepts and techniques through experiential learning. Students who have never performed a technique must be guided through the process, which is often difficult to standardize across multiple lab sections. Visual demonstration of laboratory procedures is a key element in teaching pedagogy. The main goals of the study were to create videos explaining and demonstrating a variety of lab techniques that would serve as teaching tools for undergraduate and graduate lab courses and to assess the impact of these videos on student learning. Demonstrations of individual laboratory procedures were videotaped and then edited with iMovie. Narration for the videos was edited with Audacity. Undergraduate students were surveyed anonymously prior to and following screening to assess the impact of the videos on student lab performance by completion of two Participant Perception Indicator surveys. A total of 203 and 171 students completed the pre- and posttesting surveys, respectively. Statistical analyses were performed to compare student perceptions of knowledge of, confidence in, and experience with the lab techniques before and after viewing the videos. Eleven demonstrations were recorded. Chi-square analysis revealed a significant increase in the number of students reporting increased knowledge of, confidence in, and experience with the lab techniques after viewing the videos. Incorporation of instructional videos as prelaboratory exercises has the potential to standardize techniques and to promote successful experimental outcomes.

Elevating Student Potential: Creating Digital Video to Teach Neurotransmission

PubMed Central

Jarvinen, Michael K.; Jarvinen, Lamis Z.

2012-01-01

Students today have unprecedented access to technology, the Internet, and social media. Their nearly ubiquitous use of these platforms is well documented. Given that today’s students may be primed to learn using a different medium, incorporating various technological elements into the classroom in a manner compatible with traditional approaches to teaching becomes a challenge. We recently designed and implemented a strategy that capitalized on this knowledge. Students in their first neuroscience course were required to create a 3–5 minute digital video using video-making freeware available on any Mac or PC. They used images, text, animation, as well as downloaded music to describe the fundamental process of neurotransmission as it applies to a topic of their choice. In comparison to students taught using other more traditional approaches to demonstrate the process of neurotransmission, we observed that students who took part in the video-making project exhibited better understanding of the neurological process at multiple levels, as defined by Bloom’s revised taxonomy. This was true even of students who had no aspirations of pursuing a Neuroscience career, thus suggesting that there was an overall increased level of student engagement regardless of personal career interests. The utility of our approach was validated by both direct and indirect assessments. Importantly, this particular strategy to teaching difficult concepts offers a high degree of flexibility allowing it to potentially be incorporated into any upper-level Neuroscience course.

Teaching Einsteinian physics at schools: part 1, models and analogies for relativity

NASA Astrophysics Data System (ADS)

Kaur, Tejinder; Blair, David; Moschilla, John; Stannard, Warren; Zadnik, Marjan

2017-11-01

The Einstein-First project aims to change the paradigm of school science teaching through the introduction of modern Einsteinian concepts of space and time, gravity and quanta at an early age. These concepts are rarely taught to school students despite their central importance to modern science and technology. The key to implementing the Einstein-First curriculum is the development of appropriate models and analogies. This paper is the first part of a three-paper series. It presents the conceptual foundation of our approach, based on simple physical models and analogies, followed by a detailed description of the models and analogies used to teach concepts of general and special relativity. Two accompanying papers address the teaching of quantum physics (Part 2) and research outcomes (Part 3).

Alternative conceptions of introductory geoscience students and a method to decrease them

NASA Astrophysics Data System (ADS)

Kortz, Karen Melissa

College students often leave introductory geoscience courses with alternative conceptions, and these alternative conceptions are a barrier to their grasp of geological conceptions. This dissertation clarifies the problem and suggests pedagogical strategies for correcting it. It is an integration of research on students' conceptions of geoscience topics with the application of that knowledge to the development of materials to change these conceptions to be more scientifically accurate. This research identifies and documents alternative conceptions students have in several key geoscience topics and the consequences of these alternative conception in terms of preventing understanding. After documenting the alternative conceptions, I investigate their sources. In addition, I develop ways in which the alternative conceptions can be addressed in classrooms in terms of non-traditional teaching techniques, and I assess the success of these methods. Chapter 1 addresses alternative conceptions in general introductory geoscience topics. I use known student alternative conceptions to develop a series of interactive materials to help reduce students' alternative conceptions. After their development, I assess the efficacy of these materials, and my research indicates that they are successful in helping students better learn the geoscience concepts. Chapter 2 deals with a particularly difficult topic for students---that of phylogenetic systematics. Students have an intuitive way of categorizing organisms, and this categorization is different from the system used by experts within the field. My investigation indicates the conceptual change required of students to fully understand the topic leads to great difficulties with learning. Drawing upon results of the research in Chapter 1, I developed and assessed interactive materials to help students better understand phylogenetic systematics. Using the insight gained from Chapters 1 and 2, Chapters 3 and 4 further examine students' conceptions in an area critical to understanding geology: rocks and their formation. My research indicates that students view rocks as objects independent from the processes that form and change them. In addition, I document students' alternative conceptions of rocks. Using these alternative conceptions, I look more deeply into the underlying factors that cause the difficulties students have with learning rocks, their formation, and their importance to the geosciences.

Scientists Interacting With University Science Educators

NASA Astrophysics Data System (ADS)

Spector, B. S.

2004-12-01

Scientists with limited time to devote to educating the public about their work will get the greatest multiplier effect for their investment of time by successfully interacting with university science educators. These university professors are the smallest and least publicized group of professionals in the chain of people working to create science literate citizens. They connect to all aspects of formal and informal education, influencing everything from what and how youngsters and adults learn science to legislative rulings. They commonly teach methods of teaching science to undergraduates aspiring to teach in K-12 settings and experienced teachers. They serve as agents for change to improve science education inside schools and at the state level K-16, including what science content courses are acceptable for teacher licensure. University science educators are most often housed in a College of Education or Department of Education. Significant differences in culture exist in the world in which marine scientists function and that in which university science educators function, even when they are in the same university. Subsequently, communication and building relationships between the groups is often difficult. Barriers stem from not understanding each other's roles and responsibilities; and different reward systems, assumptions about teaching and learning, use of language, approaches to research, etc. This presentation will provide suggestions to mitigate the barriers and enable scientists to leverage the multiplier effect saving much time and energy while ensuring the authenticity of their message is maintained. Likelihood that a scientist's message will retain its authenticity stems from criteria for a university science education position. These professors have undergraduate degrees in a natural science (e.g., biology, chemistry, physics, geology), and usually a master's degree in one of the sciences, a combination of natural sciences, or a master's including about eighteen hours in a natural science. Their doctorates in science education include in-depth understanding of how people construct basic science concepts and ways to mitigate conceptions not consistent with current science. They have learned ways to transform scientific information to various audiences enabling learners to construct meaningful understanding of science phenomena, the nature of science, and its historical and philosophical underpinnings. Lessons learned from current and past innovations will be presented.

A pragmatic conception of science: Implications for science teaching

NASA Astrophysics Data System (ADS)

Sessoms, Deidre Bates

In this dissertation, I examine various philosophical conceptions of the nature of science---its goals, methods and products---and link those views to how science is taught. While the review begins in the 1600s, the focus is primarily on logical positivism. The logical positivist view of science prevailed for much of the twentieth century and has greatly influenced how science is taught. The review section culminates with current conceptions of science from the fields of philosophy, sociology, feminist studies and radical studies of science. These various conceptions of the nature of science are linked to how science is currently taught, at the K--12 level and at the university. In particular, the logical positivist conception has influenced the teaching of science by emphasizing the products of science (factual knowledge and theories) over the processes of science (the social methods of knowledge production). As a result of viewing science as the logical positivists did, teachers primarily focus on science as unchanging factual knowledge, at the expense of examining the social and cultural aspects of scientific practices. I develop a pragmatic conception of the method of science as reflective thinking that we effectively use in our everyday lives. Linking that conception with the aims that John Dewey outlined for schools in a democratic society points the way towards certain goals and methods for teaching science. Therefore, I explore the type of science teaching that might result when viewing science as a pragmatic activity conducted in a democracy. Teaching of this sort would involve students in working together on shared problems that arise in the context of daily life. For science students at the university, this would include participating in and critiquing scientific research in active research laboratories. Implementing this view of science teaching might result in modifications in the practices and goals of science. Lastly, the experiences of a group of under-represented minority students who studied the sciences at the university are used to illustrate both the promises and the pitfalls of attempting to incorporate a pragmatic view of science into science teaching.

Integration of the concepts of sustainability into teaching at post-secondary institutions

NASA Astrophysics Data System (ADS)

Davis, Sara Allison

The purpose of this study was to examine the incorporation of the concepts of sustainability into teaching at two post-secondary public education residential institutions, Northern Arizona University (NAU) and the University of South Carolina (USC). A total of 17 faculty members, six administrators, and 31 students were interviewed in the study. An individual case record for each participating institution was developed. The two case records were then qualitatively cross-case analyzed to derive crosscutting themes and patterns at the two participating institutions. Based on the findings of this study, several major themes emerged across the two post-secondary public institutions. Sustainability was consistently viewed by faculty members, administrators, and students as a very broad term. While faculty members and administrators differentiated between the ecological, economic, and social dimensions of sustainability, students commonly associated sustainability more narrowly with an ecological meaning. Several common factors that influenced faculty members' and administrators' understanding of sustainability included literature, campus-wide training, personal influences, and professional networking. Common methods used by faculty to incorporate the concepts of sustainability into teaching included assigned readings, class discussions, and class projects. Key benefits of incorporating the concepts of sustainability into teaching included increased student awareness, collaboration, vision development, and social implications, while key challenges included time, support, assessment, student understanding, and more realistic classroom experiences. Key driving forces for faculty members and administrators for incorporating the concepts of sustainability into teaching were the initiatives specifically developed at the institutions. Based on the common themes at the two institutions studied, it is recommended that post-secondary institutions desiring to deploy the concepts of sustainability into teaching include the multiple dimensions of sustainability in their campus-wide initiatives, faculty and student development, and policies. In addition, it is recommended that campus-wide sustainability initiatives emphasize the key benefits of increased student awareness, collaboration, social implications, and vision development, and that they consider the challenges of time, support, assessment, and student understanding, while rewarding faculty members for their efforts to incorporate the concepts of sustainability into teaching.

Concept-Based Learning in Clinical Experiences: Bringing Theory to Clinical Education for Deep Learning.

PubMed

Nielsen, Ann

2016-07-01

Concept-based learning is used increasingly in nursing education to support the organization, transfer, and retention of knowledge. Concept-based learning activities (CBLAs) have been used in clinical education to explore key aspects of the patient situation and principles of nursing care, without responsibility for total patient care. The nature of best practices in teaching and the resultant learning are not well understood. The purpose of this multiple-case study research was to explore and describe concept-based learning in the context of clinical education in inpatient settings. Four clinical groups (each a case) were observed while they used CBLAs in the clinical setting. Major findings include that concept-based learning fosters deep learning, connection of theory with practice, and clinical judgment. Strategies used to support learning, major teaching-learning foci, and preconditions for concept-based teaching and learning will be described. Concept-based learning is promising to support integration of theory with practice and clinical judgment through application experiences with patients. [J Nurs Educ. 2016;55(7):365-371.].

The change in students' understanding of the mole concept in introductory college chemistry

NASA Astrophysics Data System (ADS)

Smith, Shane Harvie

This study investigated the difference between the students' understanding of the mole concept in chemistry at the beginning and at the end of the first semester of introductory chemistry courses. The study also identified the relationship between the criterion variable understanding of the mole concept in chemistry and the independent variables of cognitive level, type of introductory college chemistry class, and the number of lectures spent teaching the mole concept. In addition, this study examined (a) the students' misconceptions and (b) the aspects of the traditional teaching methods used in the introductory college chemistry courses that helped the students' understanding of the mole concept. This study was conducted using 180 volunteer students in their first semester of an introductory college chemistry course. These students were given a pretest instrument called the Mole Concepts Examination (MCE) to measure their understanding of the mole concept, the Group Assessment of Logical Thinking (GALT) to measure the students' cognitive level of logical thinking, and a posttest of the MCE to measure the students' understanding of the mole concept at the end of the semester. In addition, an interview was given to a selected group of 18 students to find out if the students remember the teaching techniques used to help them understand the mole concept and to determine some of the misconceptions that the students retained at the end of the semester. Results indicated a statistically significant relationship between students' understanding of the mole concept and their cognitive level. There was no significant relationship between students' understanding of the mole concept and the type of class, or the number of lectures spent teaching the mole concept. Qualitative results indicated that students were able to explain their answers to the posttest questions; students were able to identify some instructional techniques that helped them to understand the mole concept, and students of all cognitive levels retained misconceptions about the mole concept at the end of the semester.

Developing and evaluating research-informed instruction about energy in Cyprus high schools

NASA Astrophysics Data System (ADS)

Orfanidou, Dora

There is an extensive academic literature documenting students' pre-instructional interpretations of phenomena and events, showing that these interpretations are not consistent with 'energy' as used in physics. Furthermore, there is evidence showing that teaching does not always result in students' interpretations becoming consistent with teaching. This evidence has been collected across many decades and in many countries. This thesis presents a theoretical rationale for the design, implementation and evaluation of a teaching sequence aiming to promote conceptual understanding of the concept of energy to 15-16 years old physics students in Cyprus. Students' pre-instructional ideas about energy were investigated and were found to be consistent with those reported in the international literature. A design study was conducted with the aim of improving students' conceptual understanding compared to that might be expected from physics teaching usually conducted in Cyprus. Among the perspectives and the methods critically reviewed to inform the design, the perspective set out by Leach and Scott (2002) drawing on the concept of Learning Demand was chosen. Furthermore, the energy ideas proposed within the SPT11-14 project (2006) were used as a basis for the development of the theoretical framework of the teaching sequence.The research questions for the study were as follows: RQ1. What concepts of energy are used by a Cypriot cohort of upper high school students prior to teaching? RQ2. How do the conceptions and learning of the sub-cohort of Cypriot students taught through the research-informed approach compare with those following 'normal teaching' after instruction? RQ3. How do the understandings of the energy concept, of a small sub-group of students, develop during the lessons of the research-informed approach? The study involved thirty six Cypriot students in two classes of an urban upper secondary school. One of the classes acted as an intervention group, receiving the 'new' teaching sequence whilst the comparison group followed normal teaching. For addressing RQ1, data were collected through a pre-test administered to all participant students. Pre-test data and data collected through a post-test also administered to all participant students were used to test the comparative effectiveness of the teaching, thereby addressing RQ2. To address RQ3, data collected from a small number of experimental students through pre and post-test, two short-length diagnostic probes, two interviews and through an interview conducted with the experimental teacher were used.Analysis of data allowed for the following answers to each research question: RQ1: The students' pre-instructional views about the concept of energy were not within the current scientific beliefs; rather, these were within an alternative context. They were consistent with findings reported internationally in the literature. RQ2: The students' understandings of the concept of energy taught through the research-informed approach were significantly higher after instruction compared with those following 'normal teaching'. RQ3: The students' understandings of the concept of energy through the lessons of the research-informed approach were developed in a manner consistent with the intended aims of the teaching.The answers to the three research questions strongly suggest that the proposed teaching sequence for energy was found to be effective.

Film-based teaching files require a substantial investment in human, logistic, and financial resources. The combination of computer and network technology facilitates the workflow integration of distributing radiologic teaching cases within an institution (intranet) or via the World Wide Web (Internet). A digital teaching file (DTF) should include the following basic functions: image import from different sources and of different formats, editing of imported images, uniform case classification, quality control (peer review), a controlled access of different user groups (in-house and external), and an efficient retrieval strategy. The portable network graphics image format (PNG) is especially suitable for DTFs because of several features: pixel support, 2D-interlacing, gamma correction, and lossless compression. The American College of Radiology (ACR) "Index for Radiological Diagnoses" is hierarchically organized and thus an ideal classification system for a DTF. Computer-based training (CBT) in radiology is described in numerous publications, from supplementing traditional learning methods to certified education via the Internet. Attractiveness of a CBT application can be increased by integration of graphical and interactive elements but makes workflow integration of daily case input more difficult. Our DTF was built with established Internet instruments and integrated into a heterogeneous PACS/RIS environment. It facilitates a quick transfer (DICOM_Send) of selected images at the time of interpretation to the DTF and access to the DTF application at any time anywhere within the university hospital intranet employing a standard web browser. A DTF is a small but important building block in an institutional strategy of knowledge management.

Texas Science Teacher Characteristics and Conceptual Understanding of Newton's Laws of Motion

NASA Astrophysics Data System (ADS)

Busby, Karin Burk

Misconceptions of Newtonian mechanics and other physical science concepts are well documented in primary and pre-service teacher populations (Burgoon, Heddle, & Duran, 2009; Allen & Coole, 2012; Kruger, Summers, & Palacio, 1990; Ginns & Watters, 1995; Trumper, 1999; Asikainen & Hirovonen, 2014). These misconceptions match the misconceptions held by students, leaving teachers ill-equipped to rectify these concepts in the classroom (Kind, 2014; Kruger et al., 1990; Cochran & Jones, 1998). Little research has been devoted to misconceptions held by in-service secondary teachers, the population responsible for teaching Newtonian mechanics. This study focuses on Texas in-service science teachers in middle school and high school science, specifically sixth grade science, seventh grade science, eighth grade science, integrated physics and chemistry, and physics teachers. This study utilizes two instruments to gauge conceptual understanding of Newton's laws of motion: the Force Concept Inventory [FCI] (Hestenes, Wells, & Swackhamer, 1992) and a custom instrument developed for the Texas Regional Collaboratives for Excellence in Science and Mathematics Teaching (Urquhart, M., e-mail, April 4, 2017). Use of each instrument had its strengths and limitations. In the initial work of this study, the FCI was given to middle and high school teacher volunteers in two urban school districts in the Dallas- Fort Worth area to assess current conceptual understanding of Newtonian mechanics. Along with the FCI, each participant was asked to complete a demographic survey. Demographic data collected included participant's sex, years of service in teaching position, current teaching position, degrees, certification type, and current certifications for science education. Correlations between variables and overall average on the FCI were determined by t-tests and ANOVA tests with a post-hoc Holm-Bonferroni correction test. Test questions pertaining to each of Newton's three laws of motion were extrapolated to determine any correlations. The sample size for this study was small (n=24), requiring a second study investigate potential correlations to teacher characteristics. The second study was conducted using the 2013-2014 school year participants in the Texas Regional Collaboratives for Excellence in Science and Mathematics Teaching [TRC] (Texas Regional Collaborative for Excellence in Science and Mathematics Teaching, 2013), a statewide program led by The University of Texas at Austin Center for STEM Education (Texas Regional Collaborative for Excellence in Science and Mathematics Teaching, 2013). Participants completed a demographic survey and took the TRC Physics Assessment instrument developed for the TRC to determine current conceptual understanding of Newtonian mechanics as defined by the Texas Essential Knowledge and Skills. The TRC also collected demographic data including Texas Educational Agency region, participant's sex, years of service in teaching, current teaching position, level of highest degree earned, whether or not the participant had a STEM degree, and certification type. Correlations were determined between overall average and conceptual force questions only. The sample size was substantial (n=368) but due to time constraints in its development, the TRC Physics Assessment was unable to undergo reliability or validity testing before implementation. Test question pertaining to each of Newton's three laws of motion were extrapolated to determine any correlations. A significance value of p= 0.05 was used for all tests. Both content assessments indicated that, on average, teacher-participants had a considerable misunderstanding of Newtonian mechanics with Newton's third law questions especially difficult for the populations. Teachers' current teaching assignment was statistically significant for most tests, suggesting that high school physics teachers have more conceptual understanding of Newtonian mechanics than middle school teachers but have not necessarily mastered Newtonian mechanics. STEM majors and participant's sex were significant only for the TRC Physics Assessment. One outcome of this study is a recommendation that the Texas teacher certification process for middle school science change to include a general science test that includes physical science. Also, in-service science teachers responsible for teaching Newton's laws of motion should participate in specific professional development from a physics content educational expert to address misconceptions. Additional recommendations include that physics teachers take a mentoring role to help other teachers in physical science concepts and that middle school curriculum provide assistance to teachers for addressing misconceptions of Newton's third law.

Teaching children in low-income countries to assess claims about treatment effects: prioritization of key concepts.

2015-11-01

Health-related knowledge and behaviours developed during childhood are increasingly being recognized as foundational, deeply rooted and resistant to change as children mature into adulthood. The aim of this study was to engage stakeholders in prioritizing key concepts that children need to understand when assessing claims about treatment effects. A list of 30 concepts developed prior was categorized into six groups considered important for children to understand in order to assess claims about the effects of "treatments" (any type of healthcare intervention). A teachers' network was established comprising of primary school teachers, who attended a three-day meeting where the concepts were presented, discussed and prioritized using a pre-set criteria thus: (i) relevance of concepts for children, (ii) ease of comprehension of concepts for children, (iii) potential for developing resources to teach the children and (iv) whether the resources once developed would have an impact on children's ability to assess claims. Using a modified Delphi technique, participants ranked each group of concepts using the four criteria on a Likert scale of one to six (1 = lowest, 6 = highest). The rankings were analysed using STATA statistical software. Twenty-two of the 24 participants reported having understood the concepts well; with self-assessments of their own understanding above 75 on a scale of (1 to 100). All six groups of concepts were considered relevant. It is important to teach children how to assess claims about benefits and harms of treatments. Resources will be developed to teach children these concepts. © 2015 Chinese Cochrane Center, West China Hospital of Sichuan University and Wiley Publishing Asia Pty Ltd.

The concept lens diagram: a new mechanism for presenting biochemistry content in terms of "big ideas".

PubMed

Rowland, Susan L; Smith, Christopher A; Gillam, Elizabeth M A; Wright, Tony

2011-07-01

A strong, recent movement in tertiary education is the development of conceptual, or "big idea" teaching. The emphasis in course design is now on promoting key understandings, core competencies, and an understanding of connections between different fields. In biochemistry teaching, this radical shift from the content-based tradition is being driven by the "omics" information explosion; we can no longer teach all the information we have available. Biochemistry is a core, enabling discipline for much of modern scientific research, and biochemistry teaching is in urgent need of a method for delivery of conceptual frameworks. In this project, we aimed to define the key concepts in biochemistry. We find that the key concepts we defined map well onto the core science concepts recommended by the Vision and Change project. We developed a new method to present biochemistry through the lenses of these concepts. This new method challenged the way we thought about biochemistry as teachers. It also stimulated the majority of the students to think more deeply about biochemistry and to make links between biochemistry and material in other courses. This method is applicable to the full spectrum of content usually taught in biochemistry. Copyright © 2011 Wiley Periodicals, Inc.

Physics teacher use of the history of science

NASA Astrophysics Data System (ADS)

Winrich, Charles

The School of Education and the Department of Physics at Boston University offer a sequence of 10 two-credit professional development courses through the Improving the Teaching of Physics (ITOP) project. The ITOP courses combine physics content, readings from the physics education research (PER) literature, and the conceptual history of physics (CHOP). ITOP participants self-report changes to their teaching practices as a result of their participation in ITOP. The purpose of this study was to verify and characterize those changes in the specific area of the participants' use of history after their study of CHOP. Ten recent ITOP participants were observed, interviewed, and asked to provide lesson plans and samples of student work from their classes. Case studies of each participant's teaching were constructed from the data. The individual cases were synthesized to characterize the impact of CHOP on the ITOP participants. The results show that the participants integrate CHOP into their pedagogical content knowledge (PCK) to inform their understanding of: (1) the relationship between physics and other disciplines, (2) the relationship between specific physics concepts, (3) student understanding of physics concepts, (4) student difficulties in learning physics concepts, and (5) methods for teaching physics concepts. The participants use history to teach a variety of topics, although the most common were mechanics and electromagnetism. All of the participants used history to teach aspects of the nature of science (NOS) and to increase student interest in physics, while eight participants taught physics concepts through history. The predominant mode of incorporating history was through adding anecdotes about the scientists who worked on the concepts, but seven participants had their students study the historical development of physical concepts. All the participants discussed a lack of time as a factor that inhibits a greater use of history in their courses. Eight participants discussed a lack of appropriate resources for using history in high school physics classes. Two participants said they did not feel that explicit study of the history of physics would benefit their students until they had better mastery of physics concepts.

Learning by Teaching: Implementation of a Multimedia Project in Astro 101

NASA Astrophysics Data System (ADS)

Perrodin, D.; Lommen, A.

2011-09-01

Astro 101 students have deep-seated pre-conceptions regarding such topics as the cause of moon phases or the seasons. Beyond exploring the topics in a learner-centered fashion, the "learning by teaching" philosophy enables students to truly master concepts. In order to make students teach the cause of moon phases, we created a multimedia project where groups of students taught other students and filmed the session. They were to produce a 10-minute final movie highlighting their teaching techniques and showing students in the process of learning the concepts. This "experiment" turned out to be a great success for a few reasons. First, students gained experience explaining conceptually-challenging topics, making them learn the material better. Additionally, they learned to apply learner-centered techniques, most likely learning to teach for the first time. Finally, this project provided the students a connection between the classroom and the rest of the college, making them responsible for applying and sharing their knowledge with their peers.

Presented work is dedicated to improvement of teaching-learning process and classroom time utilization. What should students carry with them from the classroom? Enthusiasm of their teacher, understanding of the basic concepts, understanding of what they should work on at home and, of course, some notes Teaching materials, which relate concepts of Physics to each other and to a variety of concepts in other areas of knowledge and human activity were developed. This approach is based on my experience of interacting with students with diversity of backgrounds, educational goals and objectives. Those include Business and Politics, Literature and Media, everyday family and College life, etc. A supplement workbook based on teaching materials was developed to be available for students to make notes during the lectures. This method was tested in Introductory Physics classes at the College of Charleston during some past years. The teaching-learning effectiveness has been increased and positive feedback was received from students and faculty at the College and some other Universities.

German MedicalTeachingNetwork (MDN) implementing national standards for teacher training.

2016-01-01

An increasing demand for proof of professionalism in higher education strives for quality assurance (QA) and improvement in medical education. A wide range of teacher trainings is available to medical staff in Germany. Cross-institutional approval of individual certificates is usually a difficult and time consuming task for institutions. In case of non-acceptance it may hinder medical teachers in their professional mobility. The faculties of medicine aimed to develop a comprehensive national framework, to promote standards for formal faculty development programmes across institutions and to foster professionalization of medical teaching. Addressing the above challenges in a joint approach, the faculties set up the national MedicalTeacherNetwork (MDN). Great importance is attributed to work out nationally concerted standards for faculty development and an agreed-upon quality control process across Germany. Medical teachers benefit from these advantages due to portability of faculty development credentials from one faculty of medicine to another within the MDN system. The report outlines the process of setting up the MDN and the national faculty development programme in Germany. Success factors, strengths and limitations are discussed from an institutional, individual and general perspective. Faculties engaged in similar developments might be encouraged to transfer the MDN concept to their countries.

Supporting Interactive Teaching Methods at the New Faculty Workshop with Astronomy Lecture-Tutorials

Slater, T. F.; Brissenden, G.; Duestua, S.; Prather, E. E.

2004-05-01

Ongoing research by the Conceptual Astronomy and Physics Education Research (CAPER) Team at the University of Arizona Steward Observatory suggests that, although faculty realize that lecture-based instruction is ineffective for many students, they are not aware of what interactive teaching strategies are available, particularly for large enrollment courses. A major emphasis of the AAPT/AAS New Faculty Workshop was to introduce faculty to effective active-learning strategies based on an understanding of how people learn. Faculty were introduced to think-pair-share methods where students work together to explain difficult concepts to each other. Faculty were also introduced to authentic assessment strategies that go beyond using traditional multiple-choice tests. In particular, faculty were introduced to Lecture-Tutorials for Introductory Astronomy. The Lecture-Tutorials are instructional materials intended for use with collaborative student learning groups and are designed specifically to be easily integrated into existing courses centered on conventional lectures and do not require any outside equipment or a drastic course revision for implementation. The materials are based on research into student beliefs and reasoning difficulties and use effective instructional strategies that center on student learning. Each workshop presentation was complimented by a follow-up small group discussion session.

SU-E-E-05: Initial Experience On Physics Rotation of Radiological Residents

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

Zhang, J; Williams, D; DiSantis, D

Purpose: The new ABR core exam integrates physics into clinical teaching, with an emphasis on understanding image quality, image artifacts, radiation dose and patient safety for each modality and/or sub-specialty. Accordingly, physics training of radiological residents faces a challenge. A traditional teaching of physics through didactic lectures may not fully fulfill this goal. It is also difficult to incorporate physics teaching in clinical practice due to time constraints. A dedicated physics rotation may be a solution. This study is to evaluate a full week physics workshop developed for the first year radiological residents. Methods: The physics rotation took a fullmore » week. It included three major parts, introduction lectures, hand-on experiences and observation of technologist operation. An introduction of basic concepts was given to each modality at the beginning. Hand-on experiments were emphasized and took most of time. During hand-on experiments, residents performed radiation measurements, studied the relationship between patient dose and practice (i.e., fluoroscopy), investigated influence of acquisition parameters (i.g., kV, mAs) on image quality, and evaluated image quality using phantoms A physics test before and after the workshop was also given but not for comparison purpose. Results: The evaluation shows that the physics rotation during the first week of residency in radiology is preferred by all residents. The length of a full week of physics workshop is appropriate. All residents think that the intensive workshop can significantly benefit their coming clinical rotations. Residents become more comfortable regarding the use of radiation and counseling relevant questions such as a pregnant patient risk from a CE PE examination.

Conflicting Interpretations of Scientific Pedagogy

NASA Astrophysics Data System (ADS)

Galamba, Arthur

2016-05-01

Not surprisingly historical studies have suggested that there is a distance between concepts of teaching methods, their interpretations and their actual use in the classroom. This issue, however, is not always pitched to the personal level in historical studies, which may provide an alternative insight on how teachers conceptualise and engage with concepts of teaching methods. This article provides a case study on this level of conceptualisation by telling the story of Rómulo de Carvalho, an educator from mid-twentieth century Portugal, who for over 40 years engaged with the heuristic and Socratic methods. The overall argument is that concepts of teaching methods are open to different interpretations and are conceptualised within the melting pot of external social pressures and personal teaching preferences. The practice and thoughts of Carvalho about teaching methods are scrutinised to unveil his conflicting stances: Carvalho was a man able to question the tenets of heurism, but who publicly praised the heurism-like "discovery learning" method years later. The first part of the article contextualises the arrival of heurism in Portugal and how Carvalho attacked its philosophical tenets. In the second part, it dwells on his conflicting positions in relation to pupil-centred approaches. The article concludes with an appreciation of the embedded conflicting nature of the appropriation of concepts of teaching methods, and of Carvalho's contribution to the development of the philosophy of practical work in school science.

Teaching weight to explicitly address language ambiguities and conceptual difficulties

Language ambiguities in concept meanings can exacerbate student learning difficulties and conceptual understanding of physics concepts. This is especially true for the concept of "weight," which has multiple meanings in both scientific and everyday usage. The term weight has been defined in several different ways, with nuances, but in textbooks and teaching the term is almost always defined in one of two ways: operationally either as the contact force between an object and a measuring scale or as the gravitational force on an object due to some other body such as Earth. The use of the same name for different concepts leads to much confusion, especially in accelerating situations, and to conflicting notions of "weightlessness" in free fall situations. In the present paper, we share an innovative approach that initially avoids the term weight entirely while teaching the physics of each situation, and then teaches the language ambiguities explicitly. We developed an instructional module with this approach and implemented it over two terms in three sections of an introductory physics course for preservice elementary teachers. Learning gains for content understanding were assessed using pretests and post-tests. Participants achieved remarkably high gains for both static and accelerating situations. Surveys pre- and postinstruction showed substantially improved appreciation of language issues and ambiguities associated with weight, weightlessness, and free fall. Interviews with instructors teaching the module provided additional insight into the advantages and teaching demands of the new approach.

DLESE Teaching Box Pilot Project: Developing a Replicable Model for Collaboratively Creating Innovative Instructional Sequences Using Exemplary Resources in the Digital Library for Earth System Education (DLESE)

NASA Astrophysics Data System (ADS)

Weingroff, M.

2004-12-01

Before the advent of digital libraries, it was difficult for teachers to find suitable high-quality resources to use in their teaching. Digital libraries such as DLESE have eased the task by making high quality resources more easily accessible and providing search mechanisms that allow teachers to 'fine tune' the criteria over which they search. Searches tend to return lists of resources with some contextualizing information. However, teachers who are teaching 'out of discipline' or who have minimal training in science often need additional support to know how to use and sequence them. The Teaching Box Pilot Project was developed to address these concerns, bringing together educators, scientists, and instructional designers in a partnership to build an online framework to fully support innovative units of instruction about the Earth system. Each box integrates DLESE resources and activities, teaching tips, standards, concepts, teaching outcomes, reviews, and assessment information. Online templates and best practice guidelines are being developed that will enable teachers to create their own boxes or customize existing ones. Two boxes have been developed so far, one on weather for high school students, and one on the evidence for plate tectonics for middle schoolers. The project has met with significant enthusiasm and interest, and we hope to expand it by involving individual teachers, school systems, pre-service programs, and universities in the development and use of teaching boxes. A key ingredient in the project's success has been the close collaboration between the partners, each of whom has brought unique experiences, perspectives, knowledge, and skills to the project. This first effort involved teachers in the San Francisco Bay area, the University of California Museum of Paleontology, San Francisco State University, U.S. Geological Survey, and DLESE. This poster will allow participants to explore one of the teaching boxes. We will discuss how the boxes were developed, the conditions that engendered successful collaboration and high-quality results, lessons learned, and potential adaptations for networks of user communities, for example, in ocean education or seismology.

Bonding Ideas About Inquiry: Exploring Knowledge and Practices of Metacognition in Beginning Secondary Science Teachers

NASA Astrophysics Data System (ADS)

Rivero Arias, Ana Margarita

Metacognition, identified generally as "thinking about thinking", plays a fundamental role in science education. It enhances the understanding of science as a way to generate new knowledge using scientific concepts and practices. Moreover, metacognition supports the development of students' life-long problem solving, collaboration, and critical thinking skills. When teachers use metacognition with intention, it can promote students' agency and responsibility for their own learning. However, despite all of its benefits, metacognition is rarely seen in secondary science classrooms. Thus, it is important to understand what beginning teachers know and how they use metacognition during their first years in order to find ways to prepare and support them in incorporating metacognitive practices into their science teaching. The purpose of this multimethod study was to describe the metacognitive knowledge and experiences of beginning science teachers. For the quantitative research strand, I surveyed 36 secondary science teachers about their awareness of metacognition and used classroom observations coded from a larger research study to identify how often teachers were using metacognition to teach science. For the qualitative strand, I interviewed 15 participants about their knowledge and experiences of metacognition (including reflective practices) and spent two weeks observing two of the teachers who described exemplary metacognitive teaching practices. I found that participants had a solid awareness of metacognition, but considered the term complicated to enact, difficult for students, and less important to focus on during their first years of teaching than other elements such as content. Additionally, teaching experience seemed to have an effect on teachers' knowledge and experiences of metacognition. However, participants who were using metacognitive practices had recognized their importance since the beginning of their teaching. Reflective practices can help improve teaching, but what seems more effective is for teachers to have an experience using metacognition embedded in science content. The results of this study include a description of metacognitive teaching practices that could be helpful for secondary science teachers. The study also provides recommendations for future research, especially for teacher education programs, to promote a better understanding of metacognition while preparing secondary science teachers.

Difficult Doctors, Difficult Patients: Building Empathy.

PubMed

Anderson, Patricia F; Wescom, Elise; Carlos, Ruth C

2016-12-01

Effective doctor-patient communication facilitates the therapeutic relationship, promotes patient physical and mental health, and improves physician satisfaction. Methods of teaching effective communication use a range of techniques, typically combining didactic instruction with simulated communication encounters and reflective discussion. Rarely are patients and physicians exposed to these instructions as colearners. The evidence for the utility of graphic stories, comics, and cartoons to improve patient comprehension and self-regulation is small but encouraging. The authors describe the use of graphic medicine as a teaching tool for engendering empathy from both the physician and the patient for the other during a shared clinical encounter. This use of educational comics in a colearning experience represents a new use of the medium as a teaching tool. Copyright © 2016. Published by Elsevier Inc.

Evaluating learning and teaching using the Force Concept Inventory

Zitzewitz, Paul

1997-04-01

Teaching methods used in the calculus-based mechanics course for engineers and scientists (P150) at the University of Michigan-Dearborn were markedly changed in September, 1996. Lectures emphasize active learning with Mazur's ConcepTests, Sokoloff's Interactive Demonstrations, and Van Heuvelen's ALPS Kit worksheets. Students solve context-rich problems using Van Heuvelen's multiple representation format in cooperative groups in discussion sections. Labs were changed to use MBL emphasizing concepts and Experiment Problems to learn lab-based problem solving. Pre- and post-testing of 400 students with the Force Concept Inventory has demonstrated considerable success. The average increase in score has been 35-45methods as defined by Hake. The methods and results will be discussed. Detailed analyses of the FCI results will look at success in teaching specific concepts and the effect of student preparation in mathematics and high school physics.

Conception et evaluation d'une intervention didactique a propos des phases de la lune dans un planetarium numerique

NASA Astrophysics Data System (ADS)

Chastenay, Pierre

Since the Quebec Education Program came into effect in 2001, Quebec classrooms have again been teaching astronomy. Unfortunately, schools are ill-equipped to teach complex astronomical concepts, most of which occur outside school hours and over long periods of time. Furthermore, many astronomical phenomena involve celestial objects travelling through three-dimensional space, which we cannot access from our geocentric point of view. The lunar phases, a concept prescribed in secondary cycle one, fall into that category. Fortunately, schools can count on support from the planetarium, a science museum dedicated to presenting ultra-realistic simulations of astronomical phenomena in fast time and at any hour of the day. But what type of planetarium will support schools? Recently, planetariums also underwent their own revolution: they switched from analogue to digital, replacing geocentric opto-mechanical projectors with video projectors that offer the possibility of travelling virtually through a completely immersive simulation of the three-dimensional Universe. Although research into planetarium education has focused little on this new paradigm, certain of its conclusions, based on the study of analogue planetariums, can help us develop a rewarding teaching intervention in these new digital simulators. But other sources of inspiration will be cited, primarily the teaching of science, which views learning no longer as the transfer of knowledge, but rather as the construction of knowledge by the learners themselves, with and against their initial conceptions. The conception and use of constructivist learning environments, of which the digital planetarium is a fine example, and the use of simulations in astronomy will complete our theoretical framework and lead to the conception of a teaching intervention focusing on the lunar phases in a digital planetarium and targeting students aged 12 to 14. This teaching intervention was initially tested as part of development research (didactic engineering) aimed at improving it, both theoretically and practically, through multiple iterations in its "natural" environment, in this case an inflatable digital planetarium six metres in diameter. We are presenting the results of our first iteration, completed with help from six children aged 12 to 14 (four boys and two girls) whose conceptions about the lunar phases were noted before, during and after the intervention through group interviews, questionnaires, group exercises and recordings of the interventions throughout the activity. The evaluation was essentially qualitative, based on the traces obtained throughout the session, in particular within the planetarium itself. This material was then analyzed to validate the theoretical concepts that led to the conception of the teaching intervention and also to reveal possible ways to improve the intervention. We noted that the intervention indeed changed most participants' conceptions about the lunar phases, but also identified ways to boost its effectiveness in the future.

Impact of a concept map teaching approach on nursing students' critical thinking skills.

Nurses confront complex problems and decisions that require critical thinking in order to identify patient needs and implement best practices. An active strategy for teaching students the skills to think critically is the concept map. This study explores the development of critical thinking among nursing students in a required pathophysiology and pharmacology course during the first year of a Bachelor of Science in Nursing in response to concept mapping as an interventional strategy, using the Health Education Systems, Incorporated critical thinking test. A two-group experimental study with a pretest and posttest design was used. Participants were randomly divided into a control group (n = 42) taught by traditional didactic lecturing alone, and an intervention group (n = 41), taught by traditional didactic lecturing with concept mapping. Students in the concept mapping group performed much better on the Health Education Systems, Incorporated than students in the control group. It is recommended that deans, program directors, and nursing faculties evaluate their curricula to integrate concept map teaching strategies in courses in order to develop critical thinking abilities in their students. © 2016 John Wiley & Sons Australia, Ltd.
