Science teaching in pre-college institutions has been undergoing reform in recent years, particularly since 1996, when the National Science Education Standards were published. This reform includes inquiry-based teaching, student-centered classrooms, authentic assessment, and collaborative learning. Professional development is also recommended in the Standards document as the means for preparing teachers for reform-based teaching in pre-college classrooms. In post-secondary institutions, there is no curriculum-governing body to institute reform, and college faculty have devised their own standards and methods for teaching science, most often in the form of lecture and traditional procedure-driven laboratory exercises. This study was conducted to find examples of reform-based biology teaching in small, private, liberal arts colleges in the Southeast, where teaching innovations may be more likely to occur due to the size and independence of the schools. Professional development opportunities were also examined, since these would be important in the development of new curricula and methods of teaching. Data were collected from 151 participants, representing 78.3% of these colleges in eight southeastern states, by survey and from three volunteers by on-site interviews. Teaching was the main responsibility reported by all respondents, with both lower and upper level biology courses taught by all participants. Significant differences were found in the use of reform-based teaching in lower level biology courses versus upper level biology courses. Overall average use of inquiry-based teaching was 70.5%, while student-centered learning was reported on average by 57% of respondents, authentic assessment was reported on average by 56.6% of respondents, and collaborative learning was reported on average by 56% of respondents. Professional development opportunities most frequently used were reported to be journal, books, and videotapes. Multivariate regression analyses revealed

We all expect our students to learn facts and concepts, but more importantly, we want them to learn how to evaluate new information from an educated and skeptical perspective; that is, we want them to become critical thinkers. For many of us who are scientists and teachers, critical thought is either intuitive or we learned it so long ago that it is not at all obvious how to pass on the skills to our students. Explicitly discussing the logic that underlies the experimental basis of developmental biology is an easy and very successful way to teach critical thinking skills. Here, I describe some simple changes to a lecture course that turn the practice of critical thinking into the centerpiece of the learning process. My starting point is the "Evidence and Antibodies" sidelight in Gilbert's Developmental Biology (2000), which I use as an introduction to the ideas of correlation, necessity and sufficiency, and to the kinds of experiments required to gather each type of evidence: observation ("show it"), loss of function ("block it") and gain of function ("move it"). Thereafter, every experiment can be understood quickly by the class and discussed intelligently with a common vocabulary. Both verbal and written reinforcement of these ideas dramatically improve the students' ability to evaluate new information. In particular, they are able to evaluate claims about cause and effect; they become experts at distinguishing between correlation and causation. Because the intellectual techniques are so powerful and the logic so satisfying, the students come to view the critical assessment of knowledge as a fun puzzle and the rigorous thinking behind formulating a question as an exciting challenge.

Education research has focused on defining and identifying student learning style preferences and how to incorporate this knowledge into teaching practices that are effective in engaging student interest and transmitting information. One objective was determining the learning style preferences of undergraduate students in Biology courses at New Mexico State University by using the online VARK Questionnaire and an investigator developed survey (Self Assessed Learning Style Survey, LSS). Categories include visual, aural, read-write, kinesthetic, and multimodal. The courses differed in VARK single modal learning preferences (p = 0.035) but not in the proportions of the number of modes students preferred (p = 0.18). As elsewhere, the majority of students were multimodal. There were similarities and differences between LSS and VARK results and between students planning on attending medical school and those not. Preferences and modalities tended not to match as expected for ratings of helpfulness of images and text. To detect relationships between VARK preferred learning style and academic performance, ANOVAs were performed using modality preferences and normalized learning gains from pre and post tests over material taught in the different modalities, as well as on end of semester laboratory and lecture grades. Overall, preference did not affect the performance for a given modality based activity, quiz, or final lecture or laboratory grades (p > 0.05). This suggests that a student's preference does not predict an improved performance when supplied with material in that modality. It is recommended that methods be developed to aid learning in a variety of modalities, rather than catering to individual learning styles. Another topic that is heavily debated in the field of education is the use of simulations or videos to replace or supplement dissections. These activities were compared using normalized learning gains from pre and post tests, as well as attitude surveys
Full Text Available Evolutionary Biology integrates several disciplines of Biology in a complex and interactive manner, where a deep understanding of the subject demands knowledge in diverse areas. Since this knowledge is often inaccessible to the majority of specialized professionals, including the teachers, we present some reflections in order to stimulate discussions aimed at the improvement of the conditions of education in this area. We examine the profile of evolutionary teaching in Brazil, based on questionnaires distributed to teachers in Secondary Education in the Federal District, on data provided by the "National Institute for Educational Studies and Research", and on information collected from teachers working in various regions of this country. Issues related to biological misconceptions, curriculum and didactic material are discussed, and some proposals are presented with the objective of aiding discussions aimed at the improvement of the teaching of evolutionary biology.

Graduate students earning a doctorate in the sciences historically focus their work on research and not professional development in college science teaching. However, for those who go on to a career in academia, a majority of their time will be dedicated to teaching. During the past few years, graduate teaching assistants (GTAs) have been prepared to teach by attending a daylong workshop that included logistical information, but left pedagogy largely unexplored. Since that time, a seminar has been added to provide an introduction to pedagogical theory and practices and to provide practice teaching in the biological sciences laboratory course. Yet, more pedagogical preparation is needed. This study was conducted to determine if there was a need for a teaching certificate program for doctoral students in the College of Science and Technology (CoST) at The University of Southern Mississippi. The GTA respondents studied set teaching goals that were consistent with faculty members across the country; however, this research went further by finding out how competent the GTAs perceived they were and how much support they perceived they needed with respect to teaching and professional development. The GTAs did not differ in their perceived level of competence based on experience level; however, the less experienced GTAs did perceive they needed more support than the experienced GTAs. To help GTAs develop a skill set that many CoST graduates currently lack, it is recommended that the University provide ample training and supervision. Establishing a certificate program can potentially impact the community in the following ways: (1) the training of GTAs contributes to the academic preparation of future academic professionals who will be teaching in various institutions; (2) GTA training provides professional development and awareness that teaching requires life long professional development; (3) ensuring competent academicians, not only in content but also in pedagogy; (4

Full Text Available In recent years, increasing use of the Internet has changed English teaching methods. In this study, we constitute and propagate one new English teaching mode in colleges. It is three-dimensional which comprises online class, regular class and extracurricular activities. Its three prominent feathers include highlighting the studentsཿ important position; highlighting English comprehensive application and autonomous learning ability and extending computer network autonomous learning. Furthermore, five general implementing processes are included. Through feedback questionnaire and average marks comparison, we found that this mode improved the efficiency of experiment classes. It is hoped that this new mode would be able to assist more teachers to improve their teaching efficiency and more English learners to improve their learning efficiency.
There are substantial changes of the relationship between teaching and learning in college English teaching. On one hand, the dominant role of teachers has been changed. New teaching idea advocates the dominant role of students and also their active participation in teaching. On the other hand, the reform has combined teaching with learning which propels the interaction between them. Thus, based on the features of college English teaching, this paper, which aims to promote the quality of coll...

To document teaching evaluation practices in colleges and schools of pharmacy. A 51-item questionnaire was developed based on the instrument used in a previous study with modifications made to address changes in pharmacy education. An online survey service was used to distribute the electronic questionnaire to the deans of 98 colleges and schools of pharmacy in the United States. Completed surveys were received from 89 colleges and schools of pharmacy. All colleges/schools administered student evaluations of classroom and experiential teaching. Faculty peer evaluation of classroom teaching was used by 66% of colleges/schools. Use of other evaluation methods had increased over the previous decade, including use of formalized self-appraisal of teaching, review of teaching portfolios, interviews with samples of students, and review by teaching experts. While the majority (55%) of colleges/schools administered classroom teaching evaluations at or near the conclusion of a course, 38% administered them at the midpoint and/or conclusion of a faculty member's teaching within a team-taught course. Completion of an online evaluation form was the most common method used for evaluation of classroom (54%) and experiential teaching (72%). Teaching evaluation methods used in colleges and schools of pharmacy expanded from 1996 to 2007 to include more evaluation of experiential teaching, review by peers, formalized self-appraisal of teaching, review of teaching portfolios, interviews with samples of students, review by teaching experts, and evaluation by alumni. Procedures for conducting student evaluations of teaching have adapted to address changes in curriculum delivery and technology.

Students enrolled in a non-majors college biology course were pretested to determine their level of intellectual development, degree of field independence, mental capacity, amount of prior genetics knowledge, and amount of fluid intelligence. They were then taught a unit on Mendelian genetics. The only student variables found to not account for a significant amount of variance on a test of reading comprehension and/or a test of genetics achievement was amount of prior genetics knowledge. Developmental level was found to be the most consistent predictor of performance, suggesting that a lack of general hypothetico-deductive reasoning ability is a major factor limiting achievement among these students.

Distance education and Internet instruction are increasingly being used in college science teaching. In an effort to reach more students, Iowa State University's Human Anatomy and Physiology course was offered via Internet as well as via traditional lecture format. To assess the educational ramifications of this offering, three studies were conducted. In the first study, a collective case study approach was utilized to describe the learning environment created by an Internet-based college science course. In this study, three students were followed as they worked their way through the course. Collective case study methodologies were used to provide a rich description of the learning environment experienced by these students. Motivation, computer savvy, and academic and personal self-confidence appeared to impact the satisfaction level of the students enrolled in the class. To evaluate the effectiveness of the learning environment offered through the Internet-based science course, a quantitative comparison study was undertaken. In this study a comparison of achievement scores and study habits between students enrolled in the Internet-based class and those enrolled in the traditional section was made. Results from this study indicated that content understanding and retention did not appear to be effected by the type of instruction. Desirable study habits were reportedly used more frequently in the Internet section of the class than in the traditional class. To complete the description of the Internet course experience, a qualitative examination of Internet instructors' time commitment and level of teaching satisfaction was conducted. Data for this study consisted of interviews and researcher observations. Instructor time-on-task was initially quite high, and remained above the average spent on average face-to-face instruction in subsequent semesters. Additionally the role of the faculty member changed dramatically, causing some lessening of job satisfaction. Taken as

As the frontiers of biology become increasingly interdisciplinary, the physics education community has engaged in ongoing efforts to make physics classes more relevant to life science majors. These efforts are complicated by the many apparent differences between these fields, including the types of systems that each studies, the behavior of those systems, the kinds of measurements that each makes, and the role of mathematics in each field. Nonetheless, physics and biology are both sciences that rely on observations and measurements to construct models of the natural world. In this article, we propose that efforts to bridge the teaching of these two disciplines must emphasize shared scientific practices, particularly scientific modeling. We define modeling using language common to both disciplines and highlight how an understanding of the modeling process can help reconcile apparent differences between the teaching of physics and biology. We elaborate on how models can be used for explanatory, predictive, and functional purposes and present common models from each discipline demonstrating key modeling principles. By framing interdisciplinary teaching in the context of modeling, we aim to bridge physics and biology teaching and to equip students with modeling competencies applicable in any scientific discipline.

Evolution is fundamental to biology and scientific literacy, but teaching high school evolution is often difficult. Evolution teachers face several challenges including limited content knowledge, personal conflicts with evolution, expectations of resistance, concerns about students' conflicts with religion, and curricular constraints. Evolution teaching can be particularly challenging for student teachers who are just beginning to gain pedagogical knowledge and pedagogical content knowledge related to evolution teaching and who seek approval from university supervisors and cooperating teachers. Science teacher educators need to know how to best support student teachers as they broach the sometimes daunting task of teaching evolution within student teaching placements. This multiple case study report documents how three student teachers approached evolution instruction and what influenced their approaches. Data sources included student teacher interviews, field note observations for 4-5 days of evolution instruction, and evolution instructional artifacts. Data were analyzed using grounded theory approaches to develop individual cases and a cross-case analysis. Seven influences (state exams and standards, cooperating teacher, ideas about teaching and learning, concerns about evolution controversy, personal commitment to evolution, knowledge and preparation for teaching evolution, and own evolution learning experiences) were identified and compared across cases. Implications for science teacher preparation and future research are provided.

Evolution is a core concept of biology, and yet many college biology students do not accept evolution because of their religious beliefs. However, we do not currently know how instructors perceive their role in helping students accept evolution or how they address the perceived conflict between religion and evolution when they teach evolution. This study explores instructor practices and beliefs related to mitigating students’ perceived conflict between religion and evolution. Interviews with 32 instructors revealed that many instructors do not believe it is their goal to help students accept evolution and that most instructors do not address the perceived conflict between religion and evolution. Instructors cited many barriers to discussing religion in the context of evolution in their classes, most notably the instructors’ own personal beliefs that religion and evolution may be incompatible. These data are exploratory and are intended to stimulate a series of questions about how we as college biology instructors teach evolution. PMID:27193289

The clear and effective matching of post-secondary faculty requirements with incoming student characteristics is strongly related to undergraduate student success (National Research Council, 1996). It is especially a responsibility of secondary school biology teachers to prepare their students for introductory college biology (life science) requirements. If post-secondary faculty requirements for incoming student preparation are to be met, secondary teacher assumptions about what is required must be congruent with post-secondary faculty assumptions. The purpose of this study was to learn how well matched high school biology teachers' assumptions about the knowledge, abilities, and dispositions necessary for success in introductory college biology courses are with the knowledge, abilities, and dispositions faculty teaching introductory college biology courses assume are essential to success. The research questions were: (1) What are the secondary biology teachers' assumptions about the knowledge, abilities, and dispositions required for success in introductory college biology (life science) courses? (2) What are post-secondary biology teachers' assumptions about the knowledge, abilities, and dispositions required for success in introductory college biology (life science) courses? and (3) Do secondary biology teachers' assumptions about the knowledge, abilities, and dispositions required for success in introductory college biology (life science) courses match with those of post-secondary biology teachers'? To answer these questions, faculty were interviewed individually and the results of the interviews summarized. Then all faculty participants met in focus groups to discuss the summary data. The study included life science faculty participants from secondary and post-secondary institutions. The results of this study indicated five major findings about faculty assumptions. First, secondary and post-secondary faculty do not have the same assumptions about the

Understanding what teachers need to be more comfortable and confident in their profession is crucial to the future of effective teachers and scientific literacy in public schools. This study focuses on the experiences of Arizona biology teachers in teaching evolution, using a clinical model of stress to identify sources of pressure, the resulting stresses, and coping strategies they employ to alleviate these stresses. We conducted focus groups, one-on-one interviews, and written surveys with 15 biology teachers from the Phoenix area. On the basis of their responses, teachers were clustered into three categories: Conflicted, who struggle with their own beliefs and the possible impact of their teaching, Selective, who carefully avoid difficult topics and situations, and Scientists, who see no place for controversial social issues in their science classroom. Teachers from each group felt that they could be more effective in teaching evolution if they possessed the most up-to-date information about evolution and genomics, a safe space in which to reflect on the possible social and personal implications with their peers, and access to richer lesson plans for teaching evolution that include not only science but personal stories regarding how the lessons arose, and what problems and opportunities they created.

Full Text Available Basic concepts of cell biology are essential for scientific literacy. However, because many aspects of cell theory and cell functioning are quite abstract, students experience difficulties understanding them. In this study, we investigated whether diverse teaching resources such as the use of replicas of Leeuwenhoek’s microscope, visualization of cells using an optical microscope, construction of three-dimensional cell models, and reading of a comic book about cells could mitigate the difficulties encountered when teaching cell biology to 8th-grade primary school students. The results suggest that these didactic activities improve students’ ability to learn concrete concepts about cell biology, such as the composition of living beings, growth, and cicatrization. Also, the development of skills was observed, as, for example, the notion of cell size. However, no significant improvements were observed in students’ ability to learn about abstract topics, such as the structures of subcellular organelles and their functions. These results suggest that many students in this age have not yet concluded Piaget’s concrete operational stage, indicating that the concepts required for the significant learning of abstract subjects need to be explored more thoroughly in the process of designing programs that introduce primary school students to cell biology.

University teaching remains an area of concern, and perhaps the most difficult discipline for both teaching and learning is evolution. The concepts that underpin evolution, although complex, have been shown to be fairly straightforward, yet students arrive at and leave university with serious misconceptions, misunderstandings related to language, and often a reluctance to learn the subject because of cultural or societal pressures. Because of the unifying power of the theory, however, it is necessary not only for biology students to have a thorough understanding of evolution, but also for them to learn it in their first year so that this knowledge can then be taken into further years of study. Rather than teaching evolution at the end of a degree program, embedding it as a semester-long first-year course will ensure that a far larger number of students are made aware of misconceptions that they have brought with them from high school. Teaching through traditional passive lectures makes learning difficult conceptual material more difficult, and needs to be replaced with more interactive lectures coupled with inquiry-based practicals and small group-learning sessions to increase student engagement and interest in the subject. A new approach in pedagogy, curriculum design, and academic staff professional development is essential, especially at this time, when enrollments across science courses in many countries around the world are in decline.

The issue of student preparation for college study in science has been an ongoing concern for both college-bound students and educators of various levels. This study uses a national sample of college students enrolled in introductory biology courses to address the relationship between high school biology preparation and subsequent introductory college biology performance. Multi-Level Modeling was used to investigate the relationship between students' high school science and mathematics experiences and college biology performance. This analysis controls for student demographic and educational background factors along with factors associated with the college or university attended. The results indicated that high school course-taking and science instructional experiences have the largest impact on student achievement in the first introductory college biology course. In particular, enrollment in courses, such as high school Calculus and Advanced Placement (AP) Biology, along with biology course content that focuses on developing a deep understanding of the topics is found to be positively associated with student achievement in introductory college biology. On the other hand, experiencing high numbers of laboratory activities, demonstrations, and independent projects along with higher levels of laboratory freedom are associated with negative achievement. These findings are relevant to high school biology teachers, college students, their parents, and educators looking beyond the goal of high school graduation.

Problem-based learning (PBL) has now been introduced in at least one of its various taxonomic forms in most dental curricula. We recently developed a novel form of PBL, referred to as Context Rich Problems, which we implemented in the Oral Biology course at the Otago University Dental School. A unique event, the teaching of second and third year students in the same year, allowed us to evaluate CRPs in these two academic years simultaneously. Our findings showed that second year students were not as positive as more mature third year students in accepting the transition from a traditional didactic form of teaching to PBL. Both groups, however, found that CRPs significantly enhanced their learning experience and both groups found that they needed less time spent on preparation than they had expected. In some respects, such as previous exposure to the web and electronic media, non-New Zealanders had had a significantly higher exposure.

Used effectively, stereoscopic three-dimensional (3D) technologies can engage students with complex disciplinary content as they are presented with informative representations of abstract concepts. In addition, preliminary evidence suggests that stereoscopy may enhance learning and retention in some educational settings. Biological concepts particularly benefit from this type of presentation since complex spatially oriented structures frequently define function within these systems. Viewing biological phenomena in 3D as they are in real life allows the user to relate these spatial relationships and easily grasp concepts making the key connection between structure and function. In addition, viewing these concepts interactively in 3D and in a manner that leads to increased engagement for young prospective scientists can further increase the impact. We conducted two studies evaluating the use of this technology as an instructional tool to teach high school students complex biological concepts. The first study tested the use of stereoscopic materials for teaching brain function and human anatomy to four classes. The second study evaluated stereoscopic images to support the learning of cell structure and DNA in four different high school classes. Most important, students who used stereoscopic 3D had significantly higher test scores than those who did not. In addition, students reported enjoying 3D presentations, and it was among their top choices for learning about these complex concepts.

Previous research has suggested that adding active learning to traditional college science lectures substantially improves student learning. However, this research predominantly studied courses taught by science education researchers, who are likely to have exceptional teaching expertise. The present study investigated introductory biology courses randomly selected from a list of prominent colleges and universities to include instructors representing a broader population. We examined the relationship between active learning and student learning in the subject area of natural selection. We found no association between student learning gains and the use of active-learning instruction. Although active learning has the potential to substantially improve student learning, this research suggests that active learning, as used by typical college biology instructors, is not associated with greater learning gains. We contend that most instructors lack the rich and nuanced understanding of teaching and learning that science education researchers have developed. Therefore, active learning as designed and implemented by typical college biology instructors may superficially resemble active learning used by education researchers, but lacks the constructivist elements necessary for improving learning.

Full Text Available The multi-interactive teaching mode of college English takes students as the center and the task as the link, realizing the combination of classroom teaching and network-based autonomous learning in information technology environment. This teaching model is characterized by integrated teaching methods, open teaching environment and hierarchical teaching management compared with the traditional classroom teaching methods. This paper took the interactive teaching model of college English based on computer information technology as the research object and the "construction", "interaction" and "cooperation" as the core guiding ideology based on the learning theory of constructivism and communicative theory, guiding the design of listening, speaking and reading experiments in college English teaching under the multi-interactive teaching model. This paper first described the application and concept of multivariate interactive teaching mode, and then introduced the related learning theories. By selecting non-English major college students of 2015 from Hunan Normal University as the application object of multi-interactive teaching model, this paper validated the effectiveness of multi-interactive teaching model for college English teaching through detailed teaching experimental design and comparative analysis of teaching achievements. Under the background of the rapid development of information technology, the new multi-interactive teaching mode opens up the multi-dimensional and multi-form language learning process, which is of innovative and practical significance for the teaching of college English.

The study explored the effect of the science-technology-society (STS) and traditional teaching methods in non-majors biology classes at a community college. It investigated the efficacy of the two methods in developing cognitive abilities at Bloom's first three levels of learning. It compared retention rates in classes taught in the two methods. Changes in student attitude relating to anxiety, fear, and interest in biology were explored. The effect of each method on grade attainment among men and women was investigated. The effect of each method on grade attainment among older and younger students was examined. Results of the study indicated that no significant differences, relating to retention or student attitude, existed in classes taught in the two methods. The study found no significant cognitive gains at Bloom's first three levels in classes taught in the traditional format. In the STS classes no significant gains were uncovered at Bloom's first level of cognition. Statistically significant gains were found in the STS classes at Bloom's second and third levels of cognition. In the classes taught in the traditional format no difference was identified in grade attainment between males and females. In the STS-based classes a small correlational difference between males and females was found with males receiving lower grades than expected. No difference in grade attainment was found between older and younger students taught in the traditional format. In the STS-based classes a small statistically significant difference in grade attainment was uncovered between older and younger students with older students receiving more A's and fewer C's than expected. This study found no difference in the grades of older, female students as compared to all other students in the traditionally taught classes. A weak statistically significant difference was discovered between grade attainment of older, female students and all other students in the STS classes with older, female

Nearly half of all undergraduates are enrolled at community colleges (CCs), including the majority of U.S. students who represent groups underserved in the sciences. Yet only a small minority of studies published in discipline-based education research journals address CC biology students, faculty, courses, or authors. This marked underrepresentation of CC biology education research (BER) limits the availability of evidence that could be used to increase CC student success in biology programs. To address this issue, a diverse group of stakeholders convened at the Building Capacity for Biology Education Research at Community Colleges meeting to discuss how to increase the prevalence of CC BER and foster participation of CC faculty as BER collaborators and authors. The group identified characteristics of CCs that make them excellent environments for studying biology teaching and learning, including student diversity and institutional cultures that prioritize teaching, learning, and assessment. The group also identified constraints likely to impede BER at CCs: limited time, resources, support, and incentives, as well as misalignment between doing research and CC faculty identities as teachers. The meeting culminated with proposing strategies for faculty, administrators, journal editors, scientific societies, and funding agencies to better support CC BER. PMID:28450448

Full Text Available Shifts in enrollment patterns are affecting college classrooms and elements of teaching ranging from options for delivering course materials online to multiple methods of assessing learning. With the enrollment of more diverse college learners comes a call to intentionally design instruction that is more inclusive and responsive to multiple learning styles. The notion of Universal Design for Instruction (UDI is examined from its roots in the architectural field to its application as a model for teaching that anticipates diversity including students with disabilities. Principles of UDI are defined, and pedagogical examples are provided. Several implementation projects based on the UDI concept are described as are preliminary results regarding outcomes. Substantive issues are identified that have bearing on the direction this innovative idea will take over the next several years.

Full Text Available The biologic structures of living creatures are of difficult understanding for students, because they are usually unknown by those, in needs of strategic didactics in order to facilitate the student understanding. There are several strategies and methods for teaching, such as, analogies, metaphors, descriptions, among others. In this article we aim to identify, assess and classify the analogies used in the Higher School Biology textbooks, commonly used in Public State Schools of Manaus – AM, related to the zoology theme. The methodological procedure includes: a analysis of the whole zoological content of the most used textbooks in the public state network of Amazonas throughout the year; b three didactic textbooks have been specifically analyzed in order to specify the class taxon of “Fish” for the comparison of possible variations of types and quantities of analogies. The adopted classification of analogies was of Curtis & Reigeluth (1984 and the model of enriching analysis was according to the TWA Glynn model (Harrison & Treagust, 1993. It has been concluded that the use of analogies is greater in the content of invertebrates than that of vertebrates. Most Analogies are presented in a simple and direct manner, comparing structures, concrete to concrete, and of verbal mediation, almost nothing is presented in a diverse and heuristic manner of Zoology content on the LD. The development of limits of comparison and reflexion about the analogies was rare, only the presentation of the analogue and the target of analogy occurred.

Full Text Available A quality evaluation method is an important means and the main basis on which to evaluate the college English classroom teaching quality of teachers. To overcome the one-sided subjectivity and resulting imprecision of the traditional classroom teaching quality evaluation method, a scientific and reasonable quality evaluation index system for college English classroom teaching is constructed. The fuzzy comprehensive evaluation method and the analytic hierarchy process method are combined to propose an improved multi-level fuzzy comprehensive evaluation model for obtaining a new college English classroom teaching quality evaluation method. In the proposed method, according to the fuzzy characteristics of a college English classroom teaching quality evaluation, the fuzzy comprehensive evaluation method is used to transform the qualitative evaluation indexes into limited quantitative evaluation indexes, then a judgment matrix is constructed to determine the weights among different levels by using the analytic hierarchy process method. Additionally, the college English classroom teaching quality is evaluated in detail. Finally, an actual case of college English classroom teaching is used to verify the effectiveness of the college English classroom teaching quality evaluation method. The results show that the proposed college English classroom teaching method can overcome the subjectivity and randomness shortcomings of the traditional classroom teaching quality evaluation methods, and improve the reliability, accuracy, and objectivity of fuzzy comprehensive evaluation. It is an effective method to evaluate college English classroom teaching quality.

The present article describes teaching experiences and observations in college courses and public lectures on twins. It is concluded that much more information about twins, at both research and practical levels, requires general dissemination. This discussion is followed by reviews of recent twin research on the topics of obesity control, post-zygotic mutation, in vitro fertilization, and schisis-associated defects. Media reports of twins accused of rape, infant Chinese twins sold separately for profit, a twin CEO, and twins pursuing the same career are presented.
"Energy ideas" run through much of secondary school biology teaching. These ideas are not always consistent with each other or with the ideas used by other science disciplines. Would a change in terminology help avoid confusion or do we need to review the use of "energy" in science teaching?

The case-study teaching method has a long history (starting at least with Socrates), and wide current use in business schools, medical schools, law schools, and a variety of other disciplines. However, relatively little use is made of it in the physical sciences, specifically in physics or astronomy. The case-study method should be considered by physics faculty as part of the effort to transition the teaching of college physics from the traditional frontal-lecture format to other formats that enhance active student participation. In this paper we endeavor to interest physics instructors in the case-study method, and hope that it would also serve as a call for more instructors to produce cases that they use in their own classes and that can also be adopted by other instructors.

Full Text Available The purpose of this study is to find out facts on music teaching in Botswana Secondary Teacher Training Colleges. The authors conducted a formal study with regard to the Diploma in Secondary Education with a component of Music Education Training in Botswana. The study was conducted in Botswana at Molepolole College of Education (MCE which is the only government Secondary Teacher Training College, offering music in the whole country. Data were collected over a period of time by the three authors through meetings with staff and students surveys. The process was informed by involving all three authors. The leading author consecutively moderated this college for twelve years whilst the other two have been lecturers at the research college. This experience facilitated a further exploration of the competence frameworks in music education that they believed offered a narrow and technical view that neglected personal attributes and qualities. Apart from observations, research information was obtained through external examination/moderation reports review compiled consecutively over a number of years. Some of the information was obtained through consultation of government documents such as: The National Development Plan 10 (NDP 10, Vision 2016, Revised National Policy on Education (RNPE and Education for Kagisano with regard to prospects of music teaching in Botswana. In addition, Colleges of Education documents such as syllabuses, regulations, and prospectus were also consulted. It became evident through this research that music is accorded low status hence termed a minor subject as compared to other subjects called major. This research revealed that the admission process is also biased towards “Major” subjects. Initially there used to be interviews for “minor” opting students selection which have been since abandoned. The review found that lecturers at MCE were committed to serving for excellence yet strong criticism was made of perceived

Full Text Available It has been stated in Lithuania‘s National School Concept that the primary goal of the education of Lithuania is to secure the best possible comprehensive development of physical, psychological and spiritual human powers, to create conditions for the unfolding of the personal individuality. The subject of my teaching is economic theory. We face economic questions every day and in all areas of life. Therefore, my purpose is to acquaint college students, who do not study economics, with economic basics, to develop economic thinking and literacy. Greatest attention is paid to describe economic concepts and to use them in practice. Economics can not be learned through observing, one must work, analyse, solve practical exercises, search for correct answers. The purpose of the article is to assess the students‘ approach to the relevance of the subjects of economics. It is sought to identify the possibilities of applying new methods for teaching economic subjects and of selecting a teaching method in accordance with the students‘ level of preparation. The assessment of the research carried out enables to conclude that teaching economics forms students‘ capacities of a wide range, stimulates their self-expression, prepares young people to work in market conditions. The following methods of the research have been employed: pedagogic observation, questionnaire (survey, analysis of scientific literature and generalization.

Full Text Available The objective of this research is to describe, from the perspective of managers, how the management of teaching happens. It’s a exploratory study, conducted in in a Public University in Midwest Region. Subjects were occupants of the positions of Director, Head of Department and Course coordinator. The collection and data analysis was held by documentary surveys, semi-structured interviews and thematic analysis, respectively. The project was approved by Ethical Committee No. 796/CEP/HUJM. As main results, we identified that the management acts were based on institutional goals and objectives, materialized in PDI. Teachers were organized into working groups and research groups and extension, by area of expertise. The college management is anchored in national and institutional regulations governing the teaching profession, but they enjoy autonomy in performing their duties. The managers believe that their main role is to articulate the administrative structures and academic faculty, in order to achieve planned results. Understanding how does the management of teaching happens, helped us to suggest strategies to overcome difficulties encountered in teaching and managerial work.
Finding the time for developing or locating new class materials is one of the biggest barriers for instructors reforming their teaching approaches. Even instructors who have taken part in training workshops may feel overwhelmed by the task of transforming passive lecture content to engaging learning activities. Learning cycles have been instrumental in helping K-12 science teachers design effective instruction for decades. This paper introduces the College Science Learning Cycle adapted from the popular Biological Sciences Curriculum Study 5E to help science, technology, engineering, and mathematics faculty develop course materials to support active, student-centered teaching approaches in their classrooms. The learning cycle is embedded in backward design, a learning outcomes-oriented instructional design approach, and is accompanied by resources and examples to help faculty transform their teaching in a time-efficient manner. © 2016 M.

Large enrolment science courses play a significant role in educating undergraduate students. The discourse in these classes usually involves an instructor lecturing with little or no student participation, despite calls from current science education reform documents to elicit and utilize students' ideas in teaching. In this study, we used the 5E instructional model to develop and implement four lessons in a large enrolment introductory biology course with multiple opportunities for teacher-student and student-student interaction. Data consisted of video and audio recordings of whole-class and small-group discussions that took place throughout the study. We then used a science classroom discourse framework developed by Mortimer and Scott (2003) to characterize the discursive interactions in each 5E lesson phase. Analysis of the data resulted in two assertions. First, the purpose, communicative approach, patterns of discourse, and teaching interventions were unique to each 5E lesson phase. Second, the type of lesson topic influenced the content of the discourse. We discuss how the findings help characterize the discourse of each phase in a 5E college science lesson and propose a model to understand internalization through discursive interaction using this reform-based approach. We conclude with implications for facilitating discourse in college science lessons and future research. This study provides support for using the discourse framework to characterize discursive interaction in college science courses.

Inadequate student-teacher interactions in undergraduate courses have been linked to poor student performance. Researchers have noted that students' perceptions of student-teacher relationships may be an important factor related to student performance. The administration of a Mid-Atlantic community college prioritized increasing undergraduate biology student performance. The purpose of this quantitative study was to examine the relationship between students' biology achievement and their perceptions of interpersonal teaching behaviors and student-teacher interactions in introductory biology courses. Leary's theory on interpersonal communication and the systems communication theory of Watzlawick, Beavin, and Jackson served as the theoretical foundation. The Wubbel's Likert-scale questionnaire on student-teacher interactions was administered to 318 undergraduate biology students. Non-parametric Spearman's rank correlations revealed a significant direct correlation between students' grades and their perceptions of teachers' interpersonal teaching behaviors. The relationship between student achievement and students' perceptions of student-teacher interactions prompted the recommendation for additional study on the importance of student-teacher interactions in undergraduate programs. A recommendation for local practice included faculty development on strategies for improving student-teacher interactions. The study's implications for positive social change include increased understanding for administrators and instructors on the importance of teacher-student interactions at the community college level.

Full Text Available “Film Studies” has become one of the fastest developing disciplines at liberal arts colleges in the United States since the early 1990s. Many factors have contributed to the growth of this new teaching field, among which is the fact that new generations of college students are more accustomed than ever before to visual learning due to the influence of media technology. Also with the growth of global studies, “film” is widely used as “cultural text” through which students learn about other national histories, cultures, and customs in a visualized way that is different from conventional text-reading. Chinese language cinema, with perspectives and content distinctive from Western films, has become an innovative point in the development of Chinese studies curricula. China’s fast-paced economic development and the emergence of the Chinese cinematic movements (so-called “New Waves” of the mid-1980s have also played critical roles in drawing increased attention to Chinese cinema in classrooms in the United States.

Educational studies report that secondary and college level students have developed only limited understandings of the most basic biological processes and their interrelationships from typical classroom experiences. Furthermore, students have developed undesirable reasoning schemes and beliefs that directly affect how they make sense of and account for biological phenomena. For these reasons, there exists a need to rethink instructional practices in biology. This dissertation discusses how the principles of Harel's (1998, 2001) DNR-based instruction in mathematics could be applied to the teaching and learning of biology. DNR is an acronym for the three foundational principles of the system: Duality, Necessity, and Repeated-reasoning. This study examines the application of these three principles to ecology instruction. Through clinical and teaching interviews, I developed models of students' existing ways of understanding in ecology and inferred their ways of thinking. From these models a hypothetical learning trajectory was developed for 16 college level freshmen enrolled in a 10-week ecology teaching experiment. Through cyclical, interpretive analysis I documented and analyzed the evolution of the participants' progress. The results provide empirical evidence to support the claim that the DNR principles are applicable to ecology instruction. With respect to the Duality Principle, helping students develop specific ways of understanding led to the development of model-based reasoning---a way of thinking and the cognitive objective guiding instruction. Through carefully structured problem solving tasks, the students developed a biological understanding of the relationship between matter cycling, energy flow, and cellular processes such as photosynthesis and respiration, and used this understanding to account for observable phenomena in nature. In the case of intellectual necessity, the results illuminate how problem situations can be developed for biology learners

Graduate teaching assistants (GTAs) are used extensively as undergraduate science lab instructors at universities, yet they often have having minimal instructional training and little is known about effective training methods. This blind randomized control trial study assessed the impact of two training regimens on GTA teaching effectiveness. GTAs teaching undergraduate biology labs (n = 52) completed five hours of training in either inquiry-based learning pedagogy or general instructional “best practices”. GTA teaching effectiveness was evaluated using: (1) a nine-factor student evaluation of educational quality; (2) a six-factor questionnaire for student learning; and (3) course grades. Ratings from both GTAs and undergraduates indicated that indicated that the inquiry-based learning pedagogy training has a positive effect on GTA teaching effectiveness. PMID:24147138

Programs to help pre-college students understand the importance of Sustainability can be found around the world. A key feature for many is the collaboration among educators, researchers, and business. Two examples will be described to indicate what is being done and goals for the future. "Educação para a Sustentabilidade" ("Education for Sustainability", http://sustentabilidade.colband.net.br/) developed at the Colegio Bandeirantes in Sao Paulo, Brazil, is a popular extracurricular offering at one of Brazil's top schools that empowers students to investigate major issues facing their country and the world. They recognized that merely knowing is insufficient, so they have created several efforts towards an "environmentally friendly, socially just, and economically viable" world. The Education Project for Sustainability Science interacts with students in various grade levels within the school, participates in sustainability initiatives in other parts of the nation, and communicates electronically with like-minded programs in other countries. A second example will spotlight the CHANGE Viewer (Climate and Health Analysis for Global Education Viewer, http://climatechangehumanhealth.org/), a visualization tool that uses NASA World Wind to explore climate science through socio-economic datasets. Collaboration among scientists, programmers, and classroom educators created a suite of activities available to teach about Food Security, Water Resources, Rising Sea Level, and other themes.

This year's applicants to medical school took a newly revised version of the Medical College Admission Test. Unlike applicants in the past, they were asked to demonstrate their knowledge and use of concepts commonly taught in introductory psychology courses. The new Psychological, Social, and Biological Foundations of Behavior Test asked applicants to demonstrate the ways in which psychological, social, and biological factors influence perceptions and reactions to the world; behavior and behavior change; what people think about themselves and others; the cultural and social differences that influence well-being; and the relationships among social stratification, access to resources, and well-being. Building from the classic biopsychosocial model, this article provides the rationale for testing psychology concepts in application to medical school. It describes the concepts and skills that the new exam tests and shows how they lay the foundation for learning in medical school about the behavioral and sociocultural determinants of health. This article discusses the implications of these changes for undergraduate psychology faculty and psychology curricula as well as their importance to the profession of psychology at large.

A growing revolution is under way in the teaching of introductory science to undergraduates. It is driven by concerns about American competitiveness as well as results from recent educational research, which explains why traditional teaching approaches in large classes fail to reach many students and provides a basis for designing improved methods of instruction. Discipline-based educational research in the life sciences and other areas has identified several innovative promising practices and demonstrated their effectiveness for increasing student learning. Their widespread adoption could have a major impact on the introductory training of biology students.

Full Text Available We are presenting results of a collaborative study with a teacher from a public school in the Bahia State (northeastern Brazil. The main objective was to develop a didactic resource that could be applied in biology teaching based on intercultural dialogue, between students’ cultural knowledge and the school’s biological knowledge about mushrooms. In other words, this didactics of biology links the knowledge inherited culturally. It was applied a questionnaire with students of this school, and from the answers it was prepared Comparative Cognition tables. Relations of similarity and differences between prior knowledge of students and school biological knowledge were scored in these tables. The results revealed relationships between these two forms of knowledge, being mandatory similarity relations. These revelations were important for planning and construction of an educational game based on intercultural dialogue. The present study aims to continue with the application of this teaching resource in the classrooms of the participating teacher, looking for its viability in educational interventions in relation to the intercultural dialogue between students’ preconceptions and school science knowledge about fungi.

Progress in mathematics frequently occurs first by studying particular examples and then by generalizing the patterns that have been observed into far-reaching theorems. Similarly, in teaching mathematics one often employs examples to motivate a general principle or to illustrate its use. This volume uses the same idea in the context of learning how to teach: By analyzing particular teaching situations, one can develop broadly applicable teaching skills useful for the professional mathematician. These teaching situations are the Case Studies of the title. Just as a good mathematician seeks bot

Full Text Available This review complements another one done by the same author, in 1997, regarding the role of comprehending the concept of cell in the learning of Biology. In addition, some general papers on science education that provide a better understanding of research approaches used in the investigation of this topic have been included. The reviewed papers have been organized into categories according to the object of study, the relevance assigned to the cell concept, and the framework of analysis. The review shows that the concept of cell is very important in the biological conceptualization, however, it also shows the need of additional research on this matter, from theoretical frameworks that pay more attention to the psychological level, in order to provide some guidance to improve the teaching and learning processes of the biological content that presupose the comprehension of living beings.

The purpose of this study was to examine general and domain-specific critical thinking skills in college students, particularly ways in which these skills might be increased through the use of the case study method of teaching. General critical thinking skills were measured using the Watson-Glaser Critical Thinking Appraisal (WGCTA) Short Form, a forty-item paper-and-pencil test designed to measure important abilities involved in critical thinking, including inference, recognition of assumptions, deduction, interpretation, and evaluation of arguments. The ability to identify claims and support those claims with evidence is also an important aspect of critical thinking. I developed a new instrument, the Claim and Evidence Assessment Tool (CEAT), to measure these skills in a domain-specific manner. Forty undergraduate students in a general science course for non-science majors at a small two-year college in the northeastern United States experienced positive changes in general critical thinking according to results obtained using the Watson-Glaser Critical Thinking Appraisal (WGCTA). In addition, the students showed cumulative improvement in their ability to identify claims and evidence, as measured by the Claim and Evidence Assessment Tool (CEAT). Mean score on the WGCTA improved from 22.15 +/- 4.59 to 23.48 +/- 4.24 (out of 40), and the mean CEAT score increased from 14.98 +/- 3.28 to 16.20 +/- 3.08 (out of 24). These increases were modest but statistically and educationally significant. No differences in claim and evidence identification were found between students who learned about specific biology topics using the case study method of instruction and those who were engaged in more traditional instruction, and the students' ability to identify claims and evidence and their factual knowledge showed little if any correlation. The results of this research were inconclusive regarding whether or not the case study teaching method promotes college students' general or

The Office of Instruction and Assessment at the University of Arizona currently offers a Certificate in College Teaching Program. The objective of this program is to develop the competencies necessary to teach effectively in higher education today, with an emphasis on learner-centered teaching. This type of teaching methodology has repeatedly shown to have superior effects compared to traditional teacher-centered approaches. The success of this approach has been proven in both short term and long term teaching scenarios. Students must actively participate in class, which allows for the development of depth of understanding, acquisition of critical thinking, and problem-solving skills. As optical science graduate students completing the teaching program certificate, we taught a recitation class for OPTI 370: Photonics and Lasers for two consecutive years. The recitation was an optional 1-hour long session to supplement the course lectures. This recitation received positive feedback and learner-centered teaching was shown to be a successful method for engaging students in science, specifically in optical sciences following an inquiry driven format. This paper is intended as a guide for interactive, multifaceted teaching, due to the fact that there are a variety of learning styles found in every classroom. The techniques outlined can be implemented in many formats: a full course, recitation session, office hours and tutoring. This guide is practical and includes only the most effective and efficient strategies learned while also addressing the challenges faced, such as formulating engaging questions, using wait time and encouraging shy students.

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.

Knowing what skills underlie college success can allow students, teachers, and universities to identify and to help at-risk students. One skill that may underlie success across a variety of subject areas is structure building, the ability to create mental representations of narratives (Gernsbacher, Varner, & Faust, 1990). We tested if…

Most biologists outside the USA and a few other countries, like Australia and Canada, are under the impression that the threat to the teaching of biology represented by creationism does not concern them directly. This is unfortunately no longer true: the recent growth of creationism, especially in its pseudo-scientific manifestation known as "intelligent design", has been obvious in several countries of Western Europe, especially the UK, Germany and Poland, and it is beginning to be noticeable in Brazil, and maybe elsewhere in Latin America. The problem is complicated by the fact that there are not just two possibilities, evolution and creationism, because creationism comes in various incompatible varieties. Turkey is now a major source of creationist propaganda outside the USA, and is especially significant in relation to its influence on Muslim populations in Europe. The time for biologists to address the creationist threat is now.

The authors describe an integrated area of study for undergraduate college students that targets an increase in knowledge of mental health issues in children, adolescents, and emerging adults; encourages mental health service utilization on college campuses; and exposes young minds to the possibilities of working with children and adolescents in the mental health field. An overview of the program is provided, including the resources required to oversee and manage the program, student requirements, a description of the role that clinicians and researchers play as the program faculty, and an explanation of the tuition model. The program currently includes 40 courses with an annual enrollment of over 3000 students, resulting in departmental revenues that currently exceed $11 million per year. Student evaluations of the courses are very positive, and in a program survey students reported that their participation in the program had a positive impact on their life (84.2%) and impacted their career choice (60.2%). The benefits of the program include a valuable outreach to college students regarding the importance of seeking help for mental health issues, a positive influence on early career decision-making, opportunities for clinical and research educators to develop their scholarly areas of interest, and a significant source of departmental discretionary revenues.

In the United States (U.S.), student engagement, persistence, and academic performance levels in college science, technology, engineering, and mathematics (STEM) programs have been unsatisfactory over the last decade. Low student engagement, persistence, and academic performance in STEM disciplines have been identified as major obstacles to U.S. economic goals and U.S. science education objectives. The central and salient science identity a college student claims can influence his engagement, persistence, and academic achievement in college science. While science identity studies have been conducted on four-year college populations there is a gap in the literature concerning community college students' science identity and science performance. The purpose of this quantitative correlational study was to examine the relationship between community college students claimed science identities and engagement, persistence, and academic performance. A census sample of 264 community college students enrolled in biology during the summer of 2015 was used to study this relationship. Science identity and engagement levels were calculated using the Science Identity Centrality Scale and the Biology Motivation Questionnaire II, respectively. Persistence and final grade data were collected from institutional and instructor records. Engagement significantly correlated to, r =.534, p = .01, and varied by science identity, p < .001. Percent final grade also varied by science identity (p < .005), but this relationship was weaker (r = .208, p = .01). Results for science identity and engagement and final grade were consistent with the identity literature. Persistence did not vary by science identity in this student sample (chi2 =2.815, p = .421). This result was inconsistent with the literature on science identity and persistence. Quantitative results from this study present a mixed picture of science identity status at the community college level. It is suggested, based on the findings

Educational studies report that secondary and college level students have developed only limited understandings of the most basic biological processes and their interrelationships from typical classroom experiences. Furthermore, students have developed undesirable reasoning schemes and beliefs that directly affect how they make sense of and account for biological phenomena. For these reasons, there exists a need to rethink instructional practices in biology. This dissertation discusses how th...
Most students in the USA learn about the earth in elementary and middle school, with most of the learning in middle schools (students who are 12 to 15 years old). A few students study geosciences in high school (ages 15 to 19). In some states, for example Texas, the high-school courses are being de-emphasized, and very few students take geoscience courses after they are 15 years old. As a result, most high-school graduates know little about such important issues as global warming, air pollution, or water quality. In the USA, the geoscience curriculum is guided by national and state standards for teaching mathematics and science. But the guidance is weak. Curricula are determined essentially by local school boards and teachers with some overview by state governments. For example, the State of Texas requires all students to pass standardized examinations in science at grades 5,10, and 11. The tests are based on the Texas Essential Knowledge and Skills, the state's version of the national standards. The teaching of the geosciences, especially oceanography, is hindered by the weak guidance provided by the national standards. Because of the lack of strong guidance, textbooks include far too much material with very weak ties between the geosciences. As a result, students learn many disconnected facts, not earth system science. Improvements in the teaching of the geosciences requires a clear statement of the important in the geosciences. Why must they be taught? What must be taught? What are the major themes of geoscience research? What is important for all to know?

Full Text Available Instructors across the disciplines require their students to write literature reviews. Although numerous sources describe the literature review process, instructors and students face difficulty when approaching the structure of a literature review. This paper presents a straightforward, efficient approach for teaching students how to write a literature review. Developed over the course of three years at a university writing center, this lesson received substantial support from students across the disciplines. This paper reflects on one group of students’ experiences while writing literature reviews in a political science course, showing that students demonstrated a sense of confidence and direction after the lesson. University professors, writing center staff, and content-discipline instructors in higher education classrooms can alleviate their students’ anxiety about literature reviews by using this lesson in their classrooms.
Stimulating the interest of students in biological sciences necessitates the use of new teaching methods and motivating approaches. The idea of the self-expression assignment (SEA) has evolved from the prevalent environment at the College for Women of Kuwait University (Safat, State of Kuwait), a newly established college where the number of students is low and where students have varied backgrounds and interests and are being instructed biological sciences in English for the first time. This SEA requires each student to choose a topic among a long list of topics and interact with it in any way to produce a finished product without the interference of the course instructor. Students are told that the SEA will be graded based on their commitment, creative thinking, innovation in developing the idea, and finishing up of the chosen assignment. The SEA has been implemented in three introductory courses, namely, Biology, Introduction to Human Nutrition and Food Science, and The Human Body. Many interesting projects resulted from the SEA, and, based on an administered survey, students assessed this assignment very favorably. Students expressed their pleasure of experiencing freedom in choosing their own topics, interacting with such topics, learning more about them, and finishing up their projects. Students appreciated this type of exposure to biological sciences and expressed that such an experience enhanced their interest in such sciences.
Full Text Available Abstract The purpose of this study was to assess and determine impacts of insufficient instructional materials and ineffective lesson delivery methods on teaching in biology higher education. The participants of this study were 60 trainees who graduated in Bachelor of Sciences from eight public universities in majoring biology. Data for the study was collected while these trainees were attending the course of Biology Teaching Methods in the Post Graduate Diploma in Teaching, both in the regular and summer 2015/2016 training programs at Addis Ababa University. The study employs a mixed method design of both qualitative and quantitative data evaluations. Data was collected through classroom observations and interviews with the trainees. The findings indicated that insufficient instructional materials and ineffective teaching methods in higher education had negative impacts; that have affected the skills of performing biological tasks of graduates 71%. In the course of the Post Graduate Diploma in Teaching training, trainees were unsuccessful to conduct essential biological tasks expected from graduates of biology upon the completion of their undergraduate study program. The study was concluded with emphasis on the need to integrate theory and practice through using adequate instructional materials and proper teaching methods in the higher education biology teaching.

This study assessed financial literacy and its correlates among Turkish college students, with special emphasis on the role of formal education, learning approaches, and parental influences. Financial literacy was measured by the College Student Financial Literacy Survey, which assesses knowledge in four areas: general financial management, saving and borrowing, insurance, and investing. 853 Turkish university students were administered the survey (416 men, 437 women; M age = 20.3 yr., SD = 0.6). The mean percentage of correct responses was 45% (SD = 12.8%). Regression results showed that formal finance education in college, a deep approach to learning, and direct financial teaching by parents were significantly associated with higher financial literacy scores.
College students must complete a life science course prior to graduation for a bachelor's degree. Generally, the course has lecture and laboratory components. It is in the laboratory where there are exceptional opportunities for exploration, challenge and application of the material learned. Optimally, this would utilize the best of inquiry based approaches. Most community colleges are using a home-grown or self written laboratory manual for the direction of work in the laboratory period. Little was known about the motivation, development and adaptation of use. It was also not known about the future of the laboratory manuals in light of the recent learning reform in California Community Colleges, Student Learning Outcomes. Extensive interviews were conducted with laboratory manual authors to determine the motivation, process of development, who was involved and learning framework used in the creation of the manuals. It was further asked of manual authors their ideas about the future of the manual, the development of staff and faculty and finally, the role Student Learning Outcomes would play in the manual. Science faculty currently teaching the non-majors biology laboratories for at least two semesters were surveyed on-line about actual practice of the manual, assessment, manual flexibility, faculty training and incorporation of Student Learning Outcomes. Finally, an evaluation of the laboratory manual was done using an established Laboratory Task Analysis Instrument. Laboratory manuals were evaluated on a variety of categories to determine the level of inquiry instruction done by students in the laboratory section. The results were that the development of homegrown laboratory manuals was done by community colleges in the Los Angeles and Orange Counties in an effort to minimize the cost of the manual to the students, to utilize all the exercises in a particular lab and to effectively utilize the materials already owned by the department. Further, schools wanted to

Most American colleges and universities offer gateway biology courses to meet the needs of three undergraduate audiences: biology and related science majors, many of whom will become biomedical researchers; premedical students meeting medical school requirements and preparing for the Medical College Admissions Test (MCAT); and students completing general education (GE) graduation requirements. Biology textbooks for these three audiences present a topic scope and sequence that correlates with the topic scope and importance ratings of the biology content specifications for the MCAT regardless of the intended audience. Texts for "nonmajors," GE courses appear derived directly from their publisher's majors text. Topic scope and sequence of GE texts reflect those of "their" majors text and, indirectly, the MCAT. MCAT term density of GE texts equals or exceeds that of their corresponding majors text. Most American universities require a GE curriculum to promote a core level of academic understanding among their graduates. This includes civic scientific literacy, recognized as an essential competence for the development of public policies in an increasingly scientific and technological world. Deriving GE biology and related science texts from majors texts designed to meet very different learning objectives may defeat the scientific literacy goals of most schools' GE curricula.

Nowadays, the application of multimedia technology is most widely used in College English teaching and learning in China. Considerable money had been invested to better the technical equipments, such as multimedia classroom, computers recently, which meet each student needs. The effectiveness of multimedia has been made obvious by many teachers and students, however, it remains a controversial issue. The advantages and disadvantages in the use of multimedia technology are always being argued. It seems urgent and necessary to evaluate this new teaching mode, so the writer designed a questionnaire to seek the students' attitudinal data concerning the multimedia effectiveness. The data collected from the subjects of 150 non-English majors students, using the Experiencing English learning system and College English Integrated Course (New Edition) on CD-ROM. After statistical analysis to the valid questionnaires, the results are as follows: the students prefer multimedia to traditional teaching mode which indicate it is useful and helpful; but they do not have multimedia as a worthwhile replacement of traditional teaching modes; they generally perceive the learning on the system effective, but it will have a long way to go and attain to maturity, because the complex relationships between the teachers and the courseware, the students and courseware should be coordinated, producing a compound object among the teacher-student as well as the courseware.

Although the medical schools in Iraq recently started to increasingly use the small group teaching approach, only little is known about the students' perceptions toward this approach. Therefore, the aim of this study was to assess small group teaching as a method of teaching at Hawler College of Medicine, from the students' perspectives. This study was a qualitative study which was based on six focus group discussions which involved a sample of students from the three last years at the Hawler College of Medicine. A topic guide was used to lead the discussions and it covered questions on the positive aspects and the problems of small group teaching in the college, in addition to recommendations for its improvement. The qualitative data analysis involved a content analysis, followed by a thematic analysis. The participants were generally happy with the application of the small group teaching approach and they recognized many positive aspects which were related to this experience, which included, increasing the focus on the study subjects, enhancing the student-teacher interaction, building a better student-teacher relationship, encouraging the students' attendance, providing a better opportunity to apply a student-centered learning, enhancing a more efficient use of time and assisting in a better understanding of the subjects. The main problems which were faced, included a poor infrastructure and teaching facilities, problems which were related to examinations and the mark distribution, an improper syllabus preparation and problems which were related to the teachers' commitments and performances. The main suggestions which were put forth to improve this system, included, changing the assessment system with the focus more on the end of the course assessment, the students' involvement in the curriculum design, improving the infrastructure and teaching facilities and a better organization and management of the system. The concept of the small group teaching approach was

Alcohol use disorders and their related consequences continue to be among the nation's most prevalent and persistent healthcare problems across the lifespan. The vast majority of treatment facilities for substance use disorders in the United States report using some form of 12-step facilitation to help direct their patients to mutual help groups such as Alcoholics Anonymous (AA). Yet, many students in various healthcare disciplines may lack familiarity and direct experience with this readily accessible and potentially lifesaving, low-cost resource. AA has a long-standing tradition of extending an open invitation to professionals and providing educational materials about this worldwide program of recovery. The purpose of this article is to describe an experiential, interdisciplinary approach that has been used to teach undergraduate psychology students about AA. Associated activities included (a) selected readings, (b) attendance at an open AA meeting, (c) the formulation of thoughtful questions by the students, and (d) a single, interactive didactic session. Undergraduate psychology students responded positively when principles of experiential learning were applied to educational activities related to AA.

Past research documented that student perceptions of scientists constituted a stereotypical image that had a negative effect on the students' attitudes towards science and resulted in low numbers of students studying to become scientists and engineers in college. The present study paralleled the research on student perceptions of scientists to investigate to what extent student perceptions of science teachers affect their willingness to consider science teaching as a career. This was accomplished by surveying 91 college students and 25 science teachers at the beginning, middle, and end of the collegiate career path of becoming a science teacher. Each survey contained quantitative data utilizing seven-point semantic differential scales and written open response questions. In-depth interviews with two members of each level were conducted to supplement the survey data. The study found that college students begin college with a positive perception of teaching as a career and highly rank teachers, especially science teachers, as having a positive influence on their career path. The qualities of job enjoyment, job stability, and helping others that are characteristic of teaching were also found to be of high importance. Perceptions of the personal, social, professional, and career qualities of a science teacher were found to differ from a scientist. While both science teachers and scientists were found to be responsible, persistent, and productive, science teachers were perceived as being a distinct career possessing qualities that make them more personable, sociable, and wise than scientists. Some gender differences were detected but there was no evidence of gender bias affecting students choosing a career path to science teaching. Science teachers were perceived to be very supportive of females pursuing scientific career paths. The study also found evidence that some introductory level college students steer away from science teaching because of low salary, the lack of

The gender gap of women in science is an important and unresolved issue in higher education and occupational opportunities. The present study was motivated by the fact that there are typically fewer females than males advancing in science, and therefore fewer female science instructor role models. This observation inspired the questions: Are female college students influenced in a positive way by female science teaching assistants (TAs), and if so how can their influence be measured? The study tested the hypothesis that female TAs act as role models for female students and thereby encourage interest and increase overall performance. To test this "role model" hypothesis, the reasoning ability and self-efficacy of a sample of 724 introductory college biology students were assessed at the beginning and end of the Spring 2010 semester. Achievement was measured by exams and course work. Performance of four randomly formed groups was compared: 1) female students with female TAs, 2) male students with female TAs, 3) female students with male TAs, and 4) male students with male TAs. Based on the role model hypothesis, female students with female TAs were predicted to perform better than female students with male TAs. However, group comparisons revealed similar performances across all four groups in achievement, reasoning ability and self-efficacy. The slight differences found between the four groups in student exam and coursework scores were not statistically significant. Therefore, the results did not support the role model hypothesis. Given that both lecture professors in the present study were males, and given that professors typically have more teaching experience, finer skills and knowledge of subject matter than do TAs, a future study that includes both female science professors and female TAs, may be more likely to find support for the hypothesis.

To obtain feedback on teaching and assessment methods in professional undergraduate medical examinations. The study was conducted at Nishtar Medical College, Multan, Pakistan, from May 21 to May 26, 2012. A written questionnaire covering topics on various teaching and assessment methods was used to get feedback from students of 2nd, 3rd, 4th and 5th year M.B.B.S. SPSS version 17 was used for statistical analysis. Of the 534 questionnaires distributed, 538 (99%) were returned duly filled. Overall, 382 (71%) students were satisfied with all aspects of the lectures delivered and 393 (73%) students agreed that teaching staff was punctual in delivering lectures. Although 312 (58%) students were satisfied with the teaching conducted in the wards, students felt dissatisfaction with the teaching carried out in outpatient departments and operating theatres. Multimedia was favoured by 306 (56%) students as a supporting teaching tool. Although the students agreed that questions asked in examinations were relevant and the pattern of Objective Structured Clinical Examination (OSCE) / Objective Structured Practical Examination (OSPE) was satisfactory, they felt that the time allowed was insufficient. 399 (74%) students agreed that multiple modes of assessment improved their knowledge and skill. There was no consensus among the students on the best form of assessment. Number of students favouring short essay questions (SEQ's), multiple choice questions including true/false type, single best choice questions (BCQ'S) and descriptive questions were 209(38.8%), 176(32.7%), 70 (13%) and 28 (5%) respectively. There was disparity in students' satisfaction in internal assessment and university examination. Although 226 (42%) students were satisfied with internal assessment, 199 (37%) were satisfied with university assessment. Overall, the students were satisfied with the lectures and clinical teaching conducted in the wards. Preferred methods of assessment included short essay questions
Full Text Available In foreign-language teaching and learning, there exist a number of methodologies and approaches. The idea and principles of Task-based Language Teaching (TBLT and the task-based framework in language teaching and learning have proven to be effective in classrooms. The three pedagogic goals for task-based approaches—communication, restructuring and fluency—are also the goals of Mandarin learners. This paper explains, using examples, that the Task-based Language Teaching applied in introductory level Mandarin classes at the College of the Bahamas is helpful and that enthusiastic Bahamian learners can improve their Mandarin skills by completing various activities and tasks within the task-based framework. Observations and results obtained through using this strategy have shown that TBLT is effective in classroom Mandarin teaching and learning for Bahamian college students and adult learners, though some issues exist, which warrant further discussion.

In the complex setting of a medical school it becomes essential to utilize an approach to teaching and learning that is best suited to the needs of the students. In developing countries like India, where there is an exponential increase of institutions catering to medical students, it becomes a challenge to teach to large number of students per class. Hence, research is needed to identify the needs of students in relation to their day to day learning activities. To understand the preferences and perception of medical students about the current methods of teaching, aids used for teaching and also identify barriers in learning as perceived by the students. A Cross-sectional study was carried out at Kasturba Medical College, Mangalore during May 2012. Study participants included 2(nd) and 3(rd) year medical students. A semi-structured questionnaire was used to collect the information in relation to preferences and perceptions regarding teaching methods utilized for theory and clinical teaching. SPSS version 11.5 was used for analysis of data. The association between variables of interest was tested using Chi-square test. A total of 286 students (56.6 % females and 43.4% males) participated with a dropout rate of 10.6%. The study revealed that 71.3% of the students had an attendance above 75%. The most preferred teaching method was Problem Based Learning (PBL) (71.4%) as students felt that it enhanced lateral thinking while Didactic Lectures was the least preferred (32.8%). The most preferred modality of teaching aid was found to be Black board preferred by 46.9% students. In learning rare signs and cases, students preferred video lectures (41%) and mannequins (75.9%) in learning clinical skills. The main barrier in theory learning identified was inappropriate teaching methods (15%) and being new to clinical posting (38.5%) in case of learning clinical skills. The findings of the study suggest that a combination of traditional methods with other methods such as PBL

Training innovative talents, as one of the major aims for Chinese universities, needs to reform the traditional teaching methods. The research-oriented teaching method has been introduced and its connotation and significance for Chinese university teaching have been discussed for years. However, few practical teaching methods for routine class teaching were proposed. In this paper, a comprehensive and concrete research-oriented teaching model with contents of reference value and evaluation method for class teaching was proposed based on the current teacher-guiding teaching model in China. We proposed that the research-oriented teaching model should include at least seven aspects on: (1) telling the scientific history for the skills to find out scientific questions; (2) replaying the experiments for the skills to solve scientific problems; (3) analyzing experimental data for learning how to draw a conclusion; (4) designing virtual experiments for learning how to construct a proposal; (5) teaching the lesson as the detectives solve the crime for learning the logic in scientific exploration; (6) guiding students how to read and consult the relative references; (7) teaching students differently according to their aptitude and learning ability. In addition, we also discussed how to evaluate the effects of the research-oriented teaching model in examination.
Full Text Available An experiment was conducted to investigate methods that enable college students to learn the meaning of unknown words as they read discipline-specific academic text. Forty-one college students read specific passages aloud during three sessions. Participants were randomly assigned to three vocabulary learning interventions or a control condition. The interventions involved applying context, morphemic, and syntactic strategies; applying definitions; or applying both strategies and definitions to determine word meanings. Word learning and comprehension were measured during the interventions and in a transfer task to assess treatment effects on independent text reading. Results revealed that students in all three intervention groups outperformed controls in learning words and comprehending passages. However, the treatment groups did not differ from controls on the transfer task. Teaching both strategies and definitions was especially effective for learning unknown words and comprehending text containing those words.

Optical fiber sensor technology is one of the main contents of modern information technology, which has a very important position in modern science and technology. Fiber optic sensor experiment can improve students' enthusiasm and broaden their horizons in college physics experiment. In this paper the main structure and working principle of fiberoptical sensor with intensity compensation model are introduced. And thus fiber-optical sensor with intensity compensation model is applied to measure micro displacement of Young's modulus measurement experiment and metal linear expansion coefficient measurement experiment in the college physics experiment. Results indicate that the measurement accuracy of micro displacement is higher than that of the traditional methods using fiber-optical sensor with intensity compensation model. Meanwhile this measurement method makes the students understand on the optical fiber, sensor and nature of micro displacement measurement method and makes each experiment strengthen relationship and compatibility, which provides a new idea for the reform of experimental teaching.

I aimed to document the online undergraduate course supply in biology to evaluate how well biology educators are serving the diverse and growing population of online students. I documented online biology course offerings in the 2015-2016 academic year at 96 American colleges and universities. I quantified differences in variety, extent, and availability of courses offered by different kinds of academic institutions and characterized 149 online biology courses offered. Although there was no relationship between an institution's enrollment size and any measure of its online biology offerings, I found significantly more online biology course options at 2-year public compared with 4-year public and 4-year private schools. Courses offered for nonmajors, including students pursuing healthcare-related degrees, were three times as common as those intended for biology majors, who were more likely to be offered hybrid courses with face-to-face laboratories. These data indicate some deficiencies in online biology course options; options for students majoring in biology are limited at all types of institutions examined with a minority of 4-year institutions having any online options in biology. Significant investment of institutional resources in faculty training and technological support are necessary to develop online biology courses that will benefit a larger student population. © 2016 A.

A college for women has been cited as one of the most productive origins of female physical science doctorates in the United States. A case study was conducted to investigate teaching strategies that support the retention of women in the physical sciences, based on evidence from one of the college's most notable instructors and her teaching strategies. The strategies this teacher used included a personal "contract", confidence building techniques, and science internships. Data were collected from classroom documents, classroom observations, teacher interviews, student focus groups, student feedback sheets, Likert-response student surveys, and student final exams. Evidence from the Likert-response survey and focus groups suggested that the contract increased students' likelihood of success in the course and that confidence-building strategies improved students' confidence in their ability to succeed in science. An analysis of students' final exam scores indicated that student marks improved after the introduction of the aforementioned teaching innovations: 4% of students taking the same science course with the same teacher earned less than a C-, compared to a previous three-year average of 18% of students with below C- grades. In addition, notably fewer minority women dropped the course than they had in the past. The findings of this study suggest that this teacher's strategies may have played a part in retaining these women in the physical sciences. Based on the data, a theoretical model is proposed that suggests how switching or "fading" out of the course may have been addressed and how multiple teaching strategies can work in concert with each other to contribute to women's positive experiences in the physical sciences.

Self-efficacy is a strong predictor of academic achievement. Self-efficacy refers to the ability of college students to achieve the desired results. The metacognition level can influence college student’s self-efficacy. This study aims to identify college student’s metacognition level and self-efficacy, as well as determine the relationship between self-efficacy and metacognition level for college students of Biology Education 2013, Semarang State University. The ex-post facto quantitative research was conducted on 99 students Academic Year 2015/2016. Saturation sampling technique determined samples. E-D scale collected data for self-efficacy identification. Data for assess the metacognition level collected by Metacognitive Awareness Inventory. Data were analysed quantitatively by Pearson correlation and linear regression. Most college students have the high level of metacognition and average self-efficacy. Pearson correlation coefficient result was 0.367. This result showed that metacognition level and self-efficacy has a weak relationship. Based on linear regression test, self-efficacy influenced by metacognition level up to 13.5%. The results of the study showed that positive and significant relationships exist between metacognition level and self-efficacy. Therefore, if the metacognition level is high, then self-efficacy will also be high (appropriate).

Contemporary genomics research will impact the daily practice of biology teachers who want to teach up-to-date genetics in secondary education. This article reports on a research project aimed at enhancing biology teachers' expertise for teaching genetics situated in the context of genetic testing. The increasing body of scientific knowledge concerning genetic testing and the related consequences for decision-making indicate the societal relevance of an educational approach based on situated learning. What expertise do biology teachers need for teaching genetics in the personal health context of genetic testing? This article describes the required expertise by exploring the educational practice. Nine experienced teachers were interviewed about the pedagogical content, moral and interpersonal expertise areas concerning how to teach genetics in the personal health context of genetic testing, and the lessons of five of them were observed. The findings showed that the required teacher expertise encompasses specific pedagogical content expertise, interpersonal expertise and a preference for teacher roles and teaching approaches for the moral aspects of teaching in this context. A need for further development of teaching and learning activities for (reflection on) moral reasoning came to the fore. Suggestions regarding how to apply this expertise into context-based genetics education are discussed.

For a number of years we have been organizing and teaching a special outreach course during our Winter Study Program (the month of January). College students plan, develop, and present hands-on workshops to fourth-grade students and their parents, with faculty providing logistical support and pedagogical advice. Recent topics have been "Forensic Science", "Electricity and Magnetism", "Chemistry and Cooking", "Waves", "Natural Disasters", "Liquids", "Pressure", "Color and Light", "Momentum and Inertia", "Illusions", and "The Senses". The two-hour workshops, held one weekend on campus, emphasize hands-on experiments involving both the kids and the parents. Handouts for each workshop give instructions for doing several experiments at home. This program has been a great success for all involved: the college students gain insight into an aspect of science and what it takes to develop and teach that topic, the elementary school students participate in an exciting and challenging scientific exploration, and the parents have a chance to learn some science while spending time working on projects with their children. We provide an overview of the pedagogical aims of our current approach and a sense of the time-line for putting together such a program in a month.

The practice of learning physics contributes to the development of many transdisciplinary skills learners are able to exercise independent of the physics discipline. However, the standard practices of physics instruction do not explicitly include the monitoring or evaluation of these skills. In a competency-based (CB) learning model, the skills (competencies) are clearly defined and evaluated. We envisioned that a CB approach, where the underlying competencies are highlighted within the instructional process, would be more suitable to teaching physics to learners with diversified disciplinary interests. A model CB course curriculum was developed and practiced at Purdue University to teach introductory college physics to learners who were majoring in the technology disciplines. The experiment took place from the spring semester in 2015 until the spring semester in 2017. The practice provided a means to monitor and evaluate a set of developmental transdisciplinary competencies that underlie the learning of force and motion concepts in classical physics. Additionally, the CB practice contributed to produce substantial physics learning outcomes among learners who were underprepared to learn physics in college.

Research supports an explicit-reflective approach to teaching about nature of science (NOS), but little is reported on teachers' journeys as they attempt to integrate NOS into everyday lessons. This participatory action research paper reports the challenges and successes encountered by an in-service teacher, Sarah, implementing NOS for the first time throughout four units of a community college biology course (genetics, molecular biology, evolution, and ecology). Through the action research cycles of planning, implementing, and reflecting, Sarah identified areas of challenge and success. This paper reports emergent themes that assisted her in successfully embedding NOS within the science content. Data include weekly lesson plans and pre/post reflective journaling before and after each lesson of this lecture/lab combination class that met twice a week. This course was taught back to back semesters, and this study is based on the results of a year-long process. Developing pedagogical content knowledge (PCK) for NOS involves coming to understand the overlaps and connections between NOS, other science subject matter, pedagogical strategies, and student learning. Sarah found that through action research she was able to grow and assimilate her understanding of NOS within the biology content she was teaching. A shift in orientation toward teaching products of science to teaching science processes was a necessary shift for NOS pedagogical success. This process enabled Sarah's development of PCK for NOS. As a practical example of putting research-based instructional recommendations into practice, this study may be very useful for other teachers who are learning to teach NOS.

Full Text Available E-learning is a byproduct of instructional design. Thus online learning designers, in their approaches are expected to be familiar with the epistemological underpinnings of several theories and their consequences on the process of instruction. In the same vein constructivism holds assumptions, that learning is an active process whereby the learner constructs knowledge base on experience. Secondly, learning occurs when there is disequilibrium. It therefore takes place in a social context. Recently, technological developments are playing an important role in improving the educational process especially the integration of holographic presentation in the area. A hologram is a three-dimensional record of the positive interference of laser light waves. Teacher training in virtual holographic classrooms could help the new teachers adapt to a real problematic classroom with such tools. Nigeria being one of the moderately growing economy and a successful and relatively stable democracy, educational development is always on the increase due to commitment of government in the area. Holography is a virgin area in the Nigerian educational mindset. Colleges of education in Nigeria are basically teacher training institutions. Teachers are the backbone of education every development. This brought about the need of this study to investigate on the perception, appreciation attitude as well as acceptance of holography in teaching among the academicians in colleges of education in the Nigerian context. This study therefore in a small sample of 100 teachers survey opinions and reported the results in a descriptive statistics as well as variance (t-test and ANOVA with regards to gender and designation. On the scale of structural equation modeling (SEM tool and SPSS regression analysis as well, it presents the actual model of the modified technology acceptance model TAM. The finding indicates less positive attitude and less general acceptance of the holographic system

The purpose of this article is to determine the effectiveness of a hands-on continuing education program for practicing child and adolescent psychiatrists (CAPs) with a focus on best practices in transitioning psychiatric patients to college. The plan was to build on the unique knowledge and skill set of CAPs, use audience and facilitator feedback from prior programs to inform program content, structure, and format, and incorporate findings from the evolving literature. A 3-h interactive workshop was designed with an emphasis on audience participation. The workshop was divided into three main segments: didactics, whole group discussion/brainstorming, and small group discussion of illustrative case vignettes. Improvements and changes in knowledge, skills, and attitudes related to transition planning were identified by program participants. Quantitative feedback in the form of course evaluations, pre- and posttests, and a 6-month follow-up questionnaire indicate that the use of interactive teaching techniques is a productive learning experience for practicing CAPs. Qualitative feedback was that the discussion of the case vignettes was the most helpful. The use of a workshop format is an effective strategy to engage practicing CAPs in learning about and implementing best practices to support the transition of their patients to college and into young adulthood. Comprehensive and proactive transition planning, facilitated by clinicians, should promote the wellness of college-bound patients and help to reduce the potential risks in the setting of an upcoming transition.

Full Text Available A new teaching methodology was tested at a private college, which delivers business studyprograms on the undergraduate and graduate level. The combination of video-lectures with live classactivities (discussions, case study solving was used in the course which provides studentscompetences for managing growing small and medium-sized business. Full- and part-time studentsparticipated in the two separated classes with identical study program and the same methodologicalapproach was applied to assess the teaching approach. The main objective of the study was toexamine the possible differences between the two groups of studies. In total 126 students participatedin the study and the data collection was done with a survey. Several statistically significantdifferences were revealed. The most important finding is that part-time students were much lessenthusiastic for the delivered teaching approach. It looks like they appreciated more the liveinteraction with other students and with the teacher and probably saw the opportunity of activeparticipation as the main added value of the studies. The implication of the study is that coursedesign, which includes video, should carefully take into account the two types of students addressed.
As the medical environment and dental services change, the importance of educating dentists in responses to systemic emergencies is increasing. The current student-oriented education paradigm is moving towards training students in the abilities required to address the daily crises they will face, while also providing them with the ability to deliver knowledge. Before addressing a patient's situation, emergency physicians begin by diagnosing symptoms. As they must decide on the tests and treatments that are immediately required and must solve problems through interdisciplinary treatment, emergency physicians require additional skills and communication abilities besides clinical knowledge. Since dentistry colleges provide education that emphasizes the skills dentists require to treat oral diseases, they do not have sufficient time to teach emergency care. Additionally, because their professors lack expertise in pedagogy, dental students also have insufficient motivation to study the pathophysiology of systemic diseases. This review proposes a direction of teaching that can help dental students recognize problems and situations in emergency cases and that can help them develop their capability to immediately make a decision and resolve the problem. To do this, the author surveyed the educational philosophy and knowledge provided in the instructional design of clinical professors who give lectures on emergency care, and also examined the teaching methods of the learner-oriented education paradigm.

We present an inquiry-based, hands-on laboratory exercise on enzyme activity for an introductory college biology course for science majors. We measure student performance on a series of objective and subjective questions before and after completion of this exercise; we also measure performance of a similar cohort of students before and after completion of an existing, standard, "direct" exercise over the same topics. Although student performance on these questions increased significantly after completion of the inquiry exercise, it did not increase after completion of the control, standard exercise. Pressure to "cover" many complex topics as preparation for high-stakes examinations such as the Medical College Admissions Test may account for persistence of highly efficient, yet dubiously effective "cookbook" laboratory exercises in many science classes.
In this study, we addressed the following research question: does the concept mapping methodology, articulated with the mediated learning experience, increase meaningful learning in students attending to the cardiovascular module of a biology course?

Many undergraduate students lack a sound understanding of information literacy. The skills that comprise information literacy are particularly important when combined with scientific writing for biology majors as they are the foundation skills necessary to complete upper-division biology course assignments, better train students for research projects, and prepare students for graduate and professional education. To help undergraduate biology students develop and practice information literacy and scientific writing skills, a series of three one-hour hands-on library sessions, discussions, and homework assignments were developed for Biological Literature, a one-credit, one-hour-per-week, required sophomore-level course. The embedded course librarian developed a learning exercise that reviewed how to conduct database and web searches, the difference between primary and secondary sources, source credibility, and how to access articles through the university's databases. Students used the skills gained in the library training sessions for later writing assignments including a formal lab report and annotated bibliography. By focusing on improving information literacy skills as well as providing practice in scientific writing, Biological Literature students are better able to meet the rigors of upper-division biology courses and communicate research findings in a more professional manner.

The inconsistency of professional development (PD) in teaching for graduate teaching assistants (GTAs) is a widespread problem in higher education. Although GTAs serve an important role in retention of undergraduate science majors and in promotion of scientific literacy in nonmajors, they often lack preparation and ongoing support for teaching. Given the recent national focus on instructional quality in introductory courses, our goal was to use an online survey to identify current practices of teaching PD for biology GTAs and compare these results with the last national survey on this topic. In responses from 71 participant institutions, 96% reported some mandatory teaching preparation for biology GTAs; however, 52% of these programs required 10 or fewer hours per year. Respondents wanted to change their programs to include more pedagogical information and teaching observations with feedback to their GTAs. Programmatic self-ratings of satisfaction with GTA PD were positively correlated with the number of topics discussed during PD. Although more schools are requiring GTA PD for teaching compared with the last national survey, the lack of program breadth at many schools warrants a national conversation with regard to recent calls for improving undergraduate instruction.

Full Text Available There is concern that online education may widen the achievement gap between students from different socioeconomic classes. The recent discussion of integrating massive open online courses (MOOCs into formal higher education has added fuel to this debate. In this study, factors influencing enrollment and completion in a pre-college preparatory MOOC were explored. University of California at Irvine (UCI students of all preparation levels, defined by math Scholastic Aptitude Test (SAT score, were invited to take a Bio Prep MOOC to help them prepare for introductory biology. Students with math SAT below 550 were offered the explicit incentive of an early change to the biology major upon successful completion of the MOOC and two additional onsite courses. Our results demonstrate that, among course registrants, a higher percentage of UCI students (>60% completed the course than non-UCI registrants from the general population (<9%. Female UCI students had a greater likelihood of enrolling in the MOOC, but were not different from male students in terms of performance. University students entering with low preparation outperformed students entering who already had the credentials to become biology majors. These findings suggest that MOOCs can reach students, even those entering college with less preparation, before they enter university and have the potential to prepare them for challenging science, technology, engineering, and mathematics (STEM courses.
Online education has exploded in popularity. While there is ample research on predictors of traditional college student success, little research has been done on effective methods of predicting student success in online education. In this study, a number of demographic variables including GPA, ACT, gender, age and others were examined to determine what, if any, role they play in successfully predicting student success in an online, lab-based biology for non-majors course. Within course variables such as participation in specific categories of assignment and frequency of online visits were also examined. Groups of students including Native American/Non-Native American and Digital Immigrants and Digital Natives and others were also examined to determine if overall course success differed significantly. Good predictors of online success were found to be GPA, ACT, previous course experience and frequency of online visits with the course materials. Additionally, students who completed more of the online assignments within the course were more successful. Native American and Non-Native American students were found to differ in overall course success significantly as well. Findings indicate student academic background, previous college experience and time spent with course materials are the most important factors in course success. Recommendations include encouraging enrollment advisors to advise students about the importance of maintaining high academic levels, previous course experience and spending time with course materials may impact students' choices for online courses. A need for additional research in several areas is indicated, including Native American and Non-Native American differences. A more detailed examination of students' previous coursework would also be valuable. A study involving more courses, a larger number of students and surveys from faculty who teach online courses would help improve the generalizability of the conclusions.

This dissertation identifies and describes student and instructor perceptions that contribute to effective teaching and learning of Automata Theory in a competitive college-level Computer Science program. Effective teaching is the ability to create an appropriate learning environment in order to provide effective learning. We define effective learning as the ability of a student to meet instructor set learning objectives, demonstrating this by passing the course, while reporting a good learning experience. We conducted our investigation through a detailed qualitative case study of two sections (118 students) of Automata Theory (CS 341) at The University of Texas at Austin taught by Dr. Lily Quilt. Because Automata Theory has a fixed curriculum in the sense that many curricula and textbooks agree on what Automata Theory contains, differences being depth and amount of material to cover in a single course, a case study would allow for generalizable findings. Automata Theory is especially problematic in a Computer Science curriculum since students are not experienced in abstract thinking before taking this course, fail to understand the relevance of the theory, and prefer classes with more concrete activities such as programming. This creates a special challenge for any instructor of Automata Theory as motivation becomes critical for student learning. Through the use of student surveys, instructor interviews, classroom observation, material and course grade analysis we sought to understand what students perceived, what instructors expected of students, and how those perceptions played out in the classroom in terms of structure and instruction. Our goal was to create suggestions that would lead to a better designed course and thus a higher student success rate in Automata Theory. We created a unique theoretical basis, pedagogical positivism, on which to study college-level courses. Pedagogical positivism states that through examining instructor and student perceptions

Full Text Available Memes, the replicator of culture and information, and basic unit of culture, are copied, spread, transmitted and finally survives through imitation among vectors. The replication and transmission of memes have some resemblance to the process of second language acquisition. This paper examines the influence of language memes on the development of Chinese college students’ English writing proficiency through an empirical study. The study reveals that students instructed by the framework of teaching writing with memetics obtain an obvious improvement in their overall writing proficiency, compared with those who are instructed by the traditional method, that students’ awareness of using memes is greatly enhanced, and that language memes are significantly correlated to the students’ performance in the post-test writing. Singular language memes can be easily transmitted; memetic genotype prevails in EFL learners’ essay writing.

This paper aimed to investigate the existing ideas of nature of science (NOS) teaching in Thailand biology classroom. The study reported the existing ideas of nature of science (NOS) teaching of one biology teacher Mrs. Mali who had been teaching for 6 years at in a school in Khon Kaen city. Methodology regarded interpretive paradigm. Tools of interpretation included 2 months of classroom observation, interviewing, and questionnaire of NOS. The findings revealed Mali held good understanding of the nature of science in the aspect of the use of evidence, the aspect of knowledge inquiry through different observation and deduction, the aspect of creativity and imagination influencing science knowledge inquiry, and the aspect of changeable scientific knowledge. Her biology teaching indicated that she used both the deficient nature of science approach and the implicit nature of science approach. The implicit nature of science approach was applied mostly in 7 periods and only 2 periods were arranged using the deficient nature of science approach. The paper has implication for professional development and pre-service program on NOS teaching in Thailand.

Full Text Available The teaching of Science and Biology at school is recent, and has been practiced according to the different educational proposals, that have been developed along the last decades. The LDB (Lei nº 9.394, December, 20, 1996 proposes a pedagogical project that goes beyond the blackboard, chalk and teacher's talk in order to better prepare the students for the challenges of the labor market. Thus, this paper aims at contributing to the discussion on the teaching practice and teaching resources that can help the teaching and learning process, especially in the disciplines of Science and Biology. Based on a qualitative approach, this research aims at contributing to the construction of new knowledge that can be generated from a careful and critical look at the documentary sources. Finally, the great challenge of the educator is to make the teaching of Science and Biology pleasurable and exciting, being able to develop in students the scientific knowledge and the taste for these school subjects.

Full Text Available ”Cracking the Code” is an activity developed to demonstrate the processes of transcription and translation. This hands-on activity helps students understand the relationship between form (base pairing and function (information storage and transfer of nucleic acids. In this activity, students go through the processes of transcription and translation of a DNA molecule to create jewelry; a beaded bracelet or necklace is used as a tactile representation of a chain of amino acids. To determine the correct order of “amino acid” beads, students must first decode a strand of DNA using complementary base pairing rules. The decoding is a two-step process that illustrates transcription (the copying of DNA to RNA and translation (using tRNAs to match the genetic code to the correct amino acid. This teaches the relationship between structure (base pairs and function (information storage and transfer in nucleic acids.
1. What is usually taught as biological psychiatry in psychiatric residency training is mainly psychopharmacology, but biology has a lot more to offer to psychiatry educators. 2. The main thesis of this article is that an introductory course on the applications to psychiatry based on the theory of the evolution of the species by natural selection and mutation, along with a comprehensive theory of mind, may contribute to: (i) helping young physicians to integrate the diverse and extensive knowledge acquired during the residency training; (ii) aid in keeping the psychiatrist within the medical approach to mental illnesses while promoting the specific features of the specialty, and (iii) perhaps developing a general theoretical framework that allows psychiatrists to maintain a prominent role in the mental health staff. 3. The author describes how he has conducted such training in Venezuela. It is expected that the author's ideas will serve as a forum for discussion of this pivotal subject.

The primary goals of this dissertation were to determine the relationships between interpersonal teaching behaviors and student achievement and affective learning outcomes. The instrument used to collect student perceptions of teacher interpersonal teaching behaviors was the Questionnaire on Teacher Interactions (QTI). The instrument used to assess student affective learning outcomes was the Biology Student Affective Instrument (BSAI). The interpersonal teaching behavior data were collected using students as the observers. 111 students in an urban influenced, rural high school answered the QTI and BSAI in September 1997 and again in April 1998. At the same time students were pre and post tested using the Biology End of Course Examination (BECE). The QTI has been used primarily in European and Oceanic areas. The instrument was also primarily used in educational stratified environment. This was the first time the BSAI was used to assess student affective learning outcomes. The BECE is a Texas normed cognitive assessment test and it is used by Texas schools districts as the end of course examination in biology. The interpersonal teaching behaviors model was tested to ascertain if predictive power in the USA and in a non-stratified educational environment. Findings indicate that the QTI is an adequate predictor of student achievement in biology. The results were not congruent with the non-USA data and results, this indicates that the QTI is a society/culturally sensitive instrument and the instrument needs to be normed to a particular society/culture before it is used to affect teachers' and students' educational environments.

Information about social issues is underemphasized in college science education. This article takes the race concept as an example of this neglect. We review the history of the race concept and report the current status of the concept in textbooks and among professors. Responses to surveys of faculty at Ph.D.-granting departments indicate that 67% of biologists accept the concept of biological races in the species Homo sapiens, while only 50% of physical anthropologists do so. Content analysis of college textbooks indicates a significant degree of change over time (1936-1984) in physical anthropology but a lesser degree in biology. We suggest several reasons for the dissimilarity in the two disciplines. We propose continued use of the concept for some infrahuman species, while abandoning its application to Homo sapiens. For those biologists and anthropologists who continue to use the concept, scientific accuracy can be achieved by the presentation in lecture and text of the following ideas: first, consensus among scientists on the race concept's utility and accuracy does not exist; second, there is more variation within than between so-called races; third, discordant gradations due to natural selection, drift, and interbreeding make consistent racial boundary lines impossible to identify; fourth, past use of the race concept has had harmful consequences; fifth, the most precise study of human hereditary variation maps one trait at a time; and sixth, racial labels are misleading, especially as most populations have a cultural designation.

Full Text Available This study examined the teaching practices of 227 college instructors of introductory statistics from the health and behavioral sciences. Using primarily multidimensional scaling (MDS techniques, a two-dimensional, 10-item teaching-practice scale, TISS (Teaching of Introductory Statistics Scale, was developed. The two dimensions (subscales are characterized as constructivist and behaviorist; they are orthogonal. Criterion validity of the TISS was established in relation to instructors’ attitude toward teaching, and acceptable levels of reliability were obtained. A significantly higher level of behaviorist practice (less reform-oriented was reported by instructors from the U.S., as well as instructors with academic degrees in mathematics and engineering, whereas those with membership in professional organizations, tended to be more reform-oriented (or constructivist. The TISS, thought to be the first of its kind, will allow the statistics education community to empirically assess and describe the pedagogical approach (teaching practice of instructors of introductory statistics in the health and behavioral sciences, at the college level, and determine what learning outcomes result from the different teaching-practice orientations. Further research is required in order to be conclusive about the structural and psychometric properties of this scale, including its stability over time.

This experimental study examined the effects of participation in a Supplemental Instruction (SI) program on student performance in a college level biology course. SI is an academic support program which incorporates study techniques into the framework of an academic course through discussion sessions. According to Blanc, DeBuhr, and Martin (1983) and Kenney (1988), students who experienced Supplemental Instruction had higher course grades, semester grade point averages, and rates of re-enrollment than did non-participants. The present study was conducted within the scheduled discussion sections of a large lecture class of biology for science majors (n = 135). The researcher and another graduate student conducted these discussion sessions in which half of the sections served as the SI treatment group and half of the sections served as the non-SI (traditional) control group. This design eliminated both time on task and motivation as potential contaminating variables. This posttest only, quasi-experimental design study uses a modified nonequivalent control group design. The academic performance of students who participated in SI discussion sessions was compared to the academic performance of students who participated in traditional review-type discussion sessions. Other research questions examined the interactive effect of SI on student performance with respect to SI leader experience, student ability level as measured by total SAT scores, previous academic success as measured by previous college GPA, and different cognitive level of examination questions. t-test and ANOVA statistical methods were used to analyze the data. The results of the t-tests to compare the means of the SI group to the non-SI group (p student performance. The most important results obtained from this study are those with respect to the interactive effect of SI and student ability groups as measured by SAT total scores and prior college GPA.

Recent advances in microscope automation provide new opportunities for high-throughput cell biology, such as image-based screening. High-complex image analysis tasks often make the implementation of static and predefined processing rules a cumbersome effort. Machine-learning methods, instead, seek to use intrinsic data structure, as well as the expert annotations of biologists to infer models that can be used to solve versatile data analysis tasks. Here, we explain how machine-learning methods work and what needs to be considered for their successful application in cell biology. We outline how microscopy images can be converted into a data representation suitable for machine learning, and then introduce various state-of-the-art machine-learning algorithms, highlighting recent applications in image-based screening. Our Commentary aims to provide the biologist with a guide to the application of machine learning to microscopy assays and we therefore include extensive discussion on how to optimize experimental workflow as well as the data analysis pipeline.
Science content area literacy, particularly literacy development in college level biology, is the focus of this study. The study investigates the actions and activities of an instructor and six students over the course of 16 weeks. The study is in response to interest in the literate practices in science classes (NSES, 1996) and to the call for contextual studies that facilitate the learning of science (Borasi & Siegel, 1999; Moje, 1996; Nist & Holschuh, 1996; Prentiss, 1998). A collaborative study between the biology teacher and the researcher, this study investigates the practices believed to be effective for the development of biology literacy. Data sources, in the qualitative bounded case study (Bogdin & Biklin, 1982; Glaser & Strauss, 1967; Miles & Huberman, 1994), include: field notes of classroom observations, in-depth interviews (Seidman, 1992), class surveys, and literate artifacts. The data were coded and analyzed using a constant comparative method (Glaser & Strauss, 1967). The six students reveal similarities and differences regarding the actions, patterns, practices and use of materials and their beliefs about effective practice in the development of biology literacy. The results indicate that a variety of actions and activities are needed to facilitate the development of biology literacy. The common themes to develop from the students' data about effective teacher actions are the following: (a) involves and engages students in inquiry learning through group projects, hands-on, and group discussions; (b) relates examples, experiences, and stories; (c) exhibits expertise; (d) encourages a relaxed classroom atmosphere; (e) facilitates and coaches students; and (f) credits creativity. Further, students report their teacher to be an expert, in terms of science knowledge and literate practices, and that her expertise contributes to their understanding of biology literacy. The teachers' data reveals three themes embedded in her classroom actions: science as
Full Text Available The teacher’s skills in conducting the lesson and choice of teaching methods play an essential role in creating students’ interest in biology. The aim of the research was to study the opinion of secondary school students and biology teachers regarding the most successful teaching methods used in biology lessons and viable options to make biology lessons more interesting. The research comprised polling students and biology teachers from several schools, namely: 2 secondary schools in Jelgava, 2 in Riga and 1 in Vecumnieki. The responses revealed that 58% of students find biology lessons interesting. 56% of students indicated that their ability to focus attention during biology lessons depends on the task presented to them. Most of all they prefer watching the teacher’s presentations, listening to their teacher telling about the actual topic as well as performing laboratory work and group-work. Many students like participating in discussions, whereas a far smaller number would do various exercises, individual tasks, fill out worksheets or complete projects. Least of all students wish to work with the textbook. The methods most frequently applied by teachers are as follows: lecture, explanation, demonstration, and discussion. Teachers believe that their students prefer laboratory work and discussions as well as listening to their teacher and watching presentations or films. They also indicate at the necessity to link theory with practice and to involve information technologies. While teaching their subject biology teachers try to establish relationship between theory and real life in order to develop their students’ interest in natural processes.

Despite many calls for undergraduate biology instructors to incorporate active learning into lecture courses, few studies have focused on what it takes for instructors to make this change. We sought to investigate the process of adopting and sustaining active-learning instruction. As a framework for our research, we used the innovation-decision model, a generalized model of how individuals adopt innovations. We interviewed 17 biology instructors who were attempting to implement case study teaching and conducted qualitative text analysis on interview data. The overarching theme that emerged from our analysis was that instructors prioritized personal experience—rather than empirical evidence—in decisions regarding case study teaching. We identified personal experiences that promote case study teaching, such as anecdotal observations of student outcomes, and those that hinder case study teaching, such as insufficient teaching skills. By analyzing the differences between experienced and new case study instructors, we discovered that new case study instructors need support to deal with unsupportive colleagues and to develop the skill set needed for an active-learning classroom. We generated hypotheses that are grounded in our data about effectively supporting instructors in adopting and sustaining active-learning strategies. We also synthesized our findings with existing literature to tailor the innovation-decision model. PMID:25713092

With more than 36% of nonscience-major community college students unable to successfully complete their general life science courses, graduation and transfer rates to four-year universities are negatively affected. Many students also miss important opportunities to gain some level of science proficiency. In an effort to address the problem of poor science achievement, this research project determined which factors were most significantly related to student success in a community college biology course. It also aimed to understand the student perspectives on which modifications to the course would best help them in the pursuit of success. Drawing heavily on the educational psychology schools of thought on motivation and self-efficacy of science learning, this study surveyed and interviewed students on their perceptions of which factors were related to success in biology and the changes they believed were needed in the course structure to improve success. The data revealed that the primary factors related to student success are the students' study skills and their perceived levels of self-efficacy. The findings also uncovered the critical nature of the professor's role in influencing the success of the students. After assessing the needs of the community college population, meaningful and appropriate curriculum and pedagogical reforms could be created to improve student learning outcomes. This study offered recommendations for reforms that can be used by science practitioners to provide a more nurturing and inspiring environment for all students. These suggestions revolved around the role of the instructor in influencing the self-efficacy and study skills of students. Providing more opportunities for students to interact in class, testing more frequently, establishing peer assistance programs, managing better the course material, and making themselves more available to students were at the forefront of the list. Examples of the potential benefits of increasing

An NSF-funded project-based program was implemented by Clarkson University in 2000 to increase the interest and knowledge of middle school students in science, math and technology through the solution of an environmental problem that is relevant to their local school community. Clarkson students developed curricula for 7th and 8th grade science and technology classes and then worked with the middle school students throughout the year to reduce to transform solid waste into healthy soil for plant growth. The solution to this problem provided a vehicle to teach fundamental science and math content as well as the process of doing science and solving problems. Placing college science and engineering students in the classroom proved to be a great mechanism for engaging students in science topics and providing mentoring experiences that differ greatly from those that a practicing professional can provide. It is clear, however, that the students must be well prepared for this experience to maximize the benefits of university - school district partnership programs. The objective of this presentation will be to describe the training program that has been developed to prepare Clarkson students to work effectively in middle school classrooms. The Clarkson students are trained for their classroom experiences during the summer before they enter the classroom. They receive three credits for the training, curriculum development, and teaching efforts. It is expected that the students have the necessary background in science and technology to teach themselves the content and environmental relevance of the problem they will be teaching. Lectures and workshops focus on how to transform this knowledge into a project-based curriculum that meets the needs of the teachers, while also exciting the students. Lecture/workshops include: team work; components of an effective class and teacher; project planning and management; problem solving process; inquiry based learning, deductive

The purpose of this study was to investigate how aware high school biology teachers are of societal issues (values, moral, ethic, and legal issues) while teaching genetics, genetics engineering, molecular genetics, human heredity, and evolution. The study includes a short historical review of World War II atrocities during the Holocaust when scientists from all the above-mentioned disciplines had been involved in trying to support and develop the eugenics theories. It investigates pre- and postwar theories of the eugenics movement in the United States which were implemented successfully in Germany and a literature survey of the studies of societal issues related to these subjects. The sample consisted of 30 male and female biology teachers. Enclosed are teachers' answers in favor or against including debates about societal issues in their classrooms while teaching the disciplines mentioned above. Teachers' answers were analyzed in relation to three variables: years of teaching experience, gender, and religion faith. Data were collected from questionnaires and personal interviews and analyzed according to qualitative and quantitative methods. The results show that amongst the teachers there is a medium to low level of awareness of societal issues, while mainly emphasizing scientific subjects in preparation of matriculation examinations. The majority of the teachers do not include societal issues in their teaching, but if students raise these issues, teachers claimed to address them. No differences in teachers' opinions to societal issues were found in relation to gender or religious faith. Teachers with more years of teaching experience tend to teach with a more Science, Technology, and Society (STS) approach than novice teachers. The results are discussed in relation to teachers' professional development and teaching strategies are suggested to be used in their classrooms based on a STS approach, which includes the societal issues as a main goal.
The purpose of this study was to investigate affective outcomes and academic achievement for students enrolled in high school biology when instruction included concept-mapping. The research design was quasi-experimental and allowed for a comparison between an experimental group who constructed concept maps and a control group who received traditional biology instruction. The subjects were 140 ninth-grade students, distributed into six intact biology classes, three honors and three general biology classes. Chapter tests and a textbook generated 9-week comprehensive posttest were used to measure achievement. ANCOVA analysis on the comprehensive posttest indicated no significant overall effect of concept mapping on biology achievement across the whole quarter when controlling for the quarter pretest. Chi-square analyses were performed to measure students' attitude toward biology class and activities. The experimental group indicated higher than expected tendency to be positive about the instructional methods, however, the control group indicated fewer than expected positive responses. T-tests were conducted to determine the differences between the experimental and control groups on chapter tests with or without concept mapping. The group with concept mapping scored significantly better than those with traditional methods. Honors class comparisons indicated a significant difference between groups at pstudents benefit from concept mapping more than traditional instruction. In narrative self-evaluations, only a small percentage of participants overall listed concept mapping as the review activity that helped them learn most. Recommendations for practitioners and future research were provided related to the use of concept mapping.

The increasing body of scientific knowledge concerning genetic testing and the related consequences for decision-making indicate the societal relevance of such a situated learning approach. What content knowledge do biology teachers need for teaching genetics in the personal health context of genetic testing? This study describes the required content knowledge by exploring the educational practice and clinical genetic practices. Nine experienced teachers and 12 respondents representing the clinical genetic practices (clients, medical professionals, and medical ethicists) were interviewed about the biological concepts and ethical, legal, and social aspects (ELSA) of testing they considered relevant to empowering students as future health care clients. The ELSA suggested by the respondents were complemented by suggestions found in the literature on genetic counselling. The findings revealed that the required teacher knowledge consists of multiple layers that are embedded in specific genetic test situations: on the one hand, the knowledge of concepts represented by the curricular framework and some additional concepts (e.g. multifactorial and polygenic disorder) and, on the other hand, more knowledge of ELSA and generic characteristics of genetic test practice (uncertainty, complexity, probability, and morality). Suggestions regarding how to translate these characteristics, concepts, and ELSA into context-based genetics education are discussed.

EBI is a further education establishment which provides education in applied industrial biology at level of MSc engineering degree. Fluid mechanics at EBI was considered by students as difficult who seemed somewhat unmotivated. In order to motivate them, we applied a new play-based pedagogy. Students were asked to draw inspiration from everyday life situations to find applications of fluid mechanics and to do experiments to verify and validate some theoretical results obtained in course. In this paper, we present an innovative teaching/learning pedagogy which includes the concept of learning through play and its implications in fluid mechanics for engineering. Examples of atypical experiments in fluid mechanics made by students are presented. Based on teaching evaluation by students, it is possible to know how students feel the course. The effectiveness of this approach to motivate students is presented through an analysis of students' teaching assessment. Learning through play proved a great success in fluid...

Full Text Available This paper aimed at analyzing the academic production on Biology Teaching developed in Brazilian programs of post-graduation from 1972 to 2000. From 130 documents, 77 researches had been particularly considered, to serve as the basis for a historical-epistemological study. It was considered theses and dissertations on Education, Mathematics Education and Science Education, which provided subsidies to the analytical reference used in this paper, guided by Fleck’s epistemological conception, more specifically by the categories of thought style, thought collective, intra-collective and inter-collective circulation of thought. The content of such theses and dissertations – the problems investigated, theoretical reference and methodological procedures adopted – made possible to present and argue that, during the period investigated, different perspectives, mainly epistemological and educational, guided the academic production on Biology Teaching. Transformations that occurred in several conceptions that based the research during those three decades were identified and characterized. It was observed that the area changed from a research centered in problems related exclusively to teaching activities and faced from a empiricist-positivist perspective, into a research whose problems considered both teachers and students activities. However, those activities were analyzed by a non-empiricist epistemological conception, from which a concept of subject comes – scientists, teachers, students and researchers on Biology Teaching –, whose most remarkable characteristic is to be active and, mainly, non-neutral. It is argued that, based on Fleck’s conception, the group of researchers on Biology Teaching may be understood as thought collectives that share epistemological, educational and methodological concepts, which have been transformed as long as the area of Biology Teaching has been built. It was possible to conclude that the consolidation of

This study explored the pedagogical content knowledge (PCK) and its development of four experienced biology teachers in the context of teaching school genetics. PCK was defined in terms of teacher content knowledge, pedagogical knowledge and knowledge of students' preconceptions and learning difficulties. Data sources of teacher knowledge base included teacher-constructed concept maps, pre- and post-lesson teacher interviews, video-recorded genetics lessons, post-lesson teacher questionnaire and document analysis of teacher's reflective journals and students' work samples. The results showed that the teachers' individual PCK profiles consisted predominantly of declarative and procedural content knowledge in teaching basic genetics concepts. Conditional knowledge, which is a type of meta-knowledge for blending together declarative and procedural knowledge, was also demonstrated by some teachers. Furthermore, the teachers used topic-specific instructional strategies such as context-based teaching, illustrations, peer teaching, and analogies in diverse forms but failed to use physical models and individual or group student experimental activities to assist students' internalization of the concepts. The finding that all four teachers lacked knowledge of students' genetics-related preconceptions was equally significant. Formal university education, school context, journal reflection and professional development programmes were considered as contributing to the teachers' continuing PCK development. Implications of the findings for biology teacher education are briefly discussed.

Many teachers are not adequately prepared to help urban students who have trouble understanding conceptual ideas in biology because these students have little connection to the natural world. This study explored potential professional development strategies to help urban biology teachers use concept maps effectively with various topics in the biology curriculum. A grounded theory approach was used to develop a substantive professional development model for urban biology teachers. Qualitative data were collected through 16 semi-structured interviews of professional developers experienced in working with concept maps in the urban context. An anonymous online survey was used to collect quantitative data from 56 professional developers and teachers to support the qualitative data. The participants were from New York City, recruited through the NY Biology-Chemistry Professional Development Mentor Network and the NY Biology Teachers' Association. According to the participants, map construction, classroom applications, lesson planning, action research, follow-up workshops, and the creation of learning communities are the most effective professional development strategies. The interviewees also proposed English language learning strategies such as picture maps, native word maps, and content reading materials with underlined words. This study contributes to social change by providing a professional development model to use in planning workshops for urban teachers. Urban teachers improve their own conceptual understanding of biology while learning how to implement concept mapping strategies in the classroom. Students whose teachers are better prepared to teach biology in a conceptual manner have the potential of growing into more scientifically literate citizens.

Evolutionary developmental biology (Evo-devo) is a vibrant area of contemporary life science that should be (and is) increasingly incorporated into teaching curricula. Although the inclusion of this content is important for biological pedagogy at multiple levels of instruction, there are also philosophical lessons that can be drawn from the scientific practices found in Evo-devo. One feature of particular significance is the interdisciplinary nature of Evo-devo investigations and their resulting explanations. Instead of a single disciplinary approach being the most explanatory or fundamental, different methodologies from biological disciplines must be synthesized to generate empirically adequate explanations. Thus, Evo-devo points toward a non-reductionist epistemology in biology. I review three areas where these synthetic efforts become manifest as a result of Evo-devo's practices (form versus function reasoning styles; problem-structured investigations; idealizations related to studying model organisms), and then sketch some possible applications to teaching biology. These philosophical considerations provide resources for life science educators to address (and challenge) key aspects of the National Science Education Standards and Benchmarks for Scientific Literacy.

In this first chapter of the series "Teaching molecular genetics," an introduction to molecular genetics is presented. We describe the structure of DNA and genes and explain in detail the central dogma of molecular biology, that is, the flow of genetic information from DNA via RNA to polypeptide (protein). In addition, several basic and frequently used general molecular tools, such as restriction enzymes, Southern blotting, DNA amplification and sequencing are discussed, in order to lay the foundations for the forthcoming chapters.
This study is an interpretive inquiry into how students and teachers understand the question, "What does it mean to teach biology well?" It explores the participants' experience of the biology classroom and how they navigate between the expectations of external factors, such as diploma examinations, post-secondary requirements, and the demands of the Alberta Education Program of Studies' expectations of teaching through an inquiry-based focus. The study explores the tensions that the students and teachers experience as they navigate between the expectations for post-secondary education and the time constraints of covering the curriculum. Through a hermeneutic frame, some of the experiences and assumptions about understandings are explored in depth. The findings discuss teachers' sense of conflict between wanting students to have an opportunity to explore the process and complexity of science with their sense of issues with time, expectations to cover an expansive curriculum and the expectations to prepare students for post-secondary science. This study unpacks these experiences through researching the historical arguments that teachers have inherited, exploring the continual stress of running out of time, and exploring how relationships was seen as the most essential component of teaching biology.

Practical classes on protein expression and purification were given to undergraduate biology students enrolled in the elective course "Introduction to Genetic Engineering." The heterologous expression of the green fluorescent protein (GFP)* of Aequorea victoria is an interesting system for didactic purposes because it can be viewed easily during experiments. The students were provided with basic information about the molecular features and applications of the GFP in molecular biology, the available heterologous expression systems, and the theoretical and experimental details of GFP expression in Escherichia coli and its purification. E. coli BL21-competent cells were transformed with the pET28a expression vector containing the GFP gene fused to a histidine (His) tag. During the induction of a transformed clone by isopropylthiogalactoside, a time course for GFP expression was analyzed by SDS-PAGE, and the expression was also visualized by the increasing green fluorescence of the bacterial culture. After cellular disruption, protein purification was illustrated by affinity chromatography of the His-tagged protein in a nickel column. Eluted fractions containing imidazole in increasing concentrations were analyzed visually and also by SDS-PAGE, demonstrating the role of imidazole in protein recovery by competition with nonspecific proteins and the His-tagged protein. The results obtained and the experimental factors involved in protein expression, solubilization, and folding were discussed following the laboratory experiments. These practical classes allowed several current approaches to molecular biology to be demonstrated rapidly and helped underscore some of the topics taught during the course.

Full Text Available Online learning environments provide an unprecedented opportunity to increase student access to higher education. Accomplishing this much needed goal requires the active participation and cooperation of university faculty from a broad spectrum of institutional settings. Although online learning has seen rapid growth in recent years, it remains a relatively small percentage of the entire curriculum of higher education today. As a relatively recent development, online teaching can be viewed through the lens of diffusion of innovation research. This paper reports on research from 913 professors from community colleges, four-year colleges, and university centers in an attempt to determine potential barriers to the continued growth in adoption of online teaching in higher education. It is concluded through factor and regression analysis that four variables are significantly associated with faculty satisfaction and their likelihood, therefore, to adopt or continue online teaching – these include levels of interaction in their online course, technical support, a positive learning experience in developing and teaching the course, and the discipline area in which they taught. Recommendations for institutional policy, faculty development, and further research are included.

Full Text Available Information and communication technologies (ICT such as computers, multimedia systems, productivity software, and the Internet have greatly improved the performance of different organizations and influenced higher learning institutions like Sorsogon State College (SSC to develop and implement innovative teaching and learning methods. However, despite the many benefits of ICT when used in education, there are still faculty members who do not use these technologies for teaching. Hence, this research was conducted to assess their readiness for teaching with ICT. Findings revealed that most of the surveyed respondents were above forty-five years old, have 1-10 years of government service, and have specialization in the field of education. In terms of readiness to teach with ICT, the results disclosed that they were fairly ready along human-resource readiness, ready along technological skill readiness, and much ready along equipment readiness. Their age was not significantly related to their human resource readiness but significantly related to their technological skill and equipment readiness. The respondents’ number of years in the government was significantly related to their readiness to teach with ICT in terms of human resource, technological skill, and equipment readiness. Their field of specialization was not significantly related to their readiness to teach with ICT. Among the most identified factors why some of them do not use ICT resources were unavailability of ICT resources, lack of knowledge and lack of familiarity to ICT. The output of this research is a faculty training program to enhance their know

The purpose of this study was to examine the effects of Peer Instruction (PI) in a state college biology classroom. Students discussed biological concepts in the area of genetics among their peers during class time. Conceptual questions were delivered to the student in the form of ConcepTests, conceptual questions designed to uncover students' misconceptions in the material. Students first answered a question projected from the computer to an overhead screen on their own. Depending on the percentage of students that answered correctly, students then discussed their answers with their peers (PI). These discussions allowed students to uncover their misunderstandings in the material by asking them to think about what they know and what they don't know. Students' initial and secondary responses to the related questions gave the instructor a real time instant view of the collective class' conceptual understanding of concepts being covered. This study was a quasi-experimental, pretest-posttest, control group design. The sample consisted of 134 students enrolled in General Biology (BSCC 1010) a Eastern Florida State College (EFSC) in Palm Bay, Florida. Both control N = 62 and experimental groups N = 72 were comprised of whole intact classes during the Fall 2014 semester. The control groups received traditional lecture content during the course of the study. They had access to conceptual questions but they were not used in a Peer Instruction format during class time. A statistical analysis was conducted after the completion of pre-tests and posttests during the Fall 2014 semester. Although there was an increase in test scores in the experimental group compared to the control, the results were not significant with p = 0.0687 at an alpha level of .05. No significant difference was found in retention p= 0.5954, gender p = 0.4487 or past science coursework p = 0.6695 between classes that engaged in PI and classes that were taught in traditional lecture-based classes.

Full Text Available Background: The gradual increase in the number of learners admitted into a nursing college in Gauteng resulted in an increase in class size without a proportional increase in the number of nurse educators.Objectives: To explore and describe the experiences of nurse educators teaching in large classes at a nursing college in Gauteng in order to present recommendations to facilitate teaching and learning.Method: A qualitative, exploratory, descriptive, and phenomenological research design which is contextual in nature was used. A total of 20 nurse educators were selected through purposive sampling, and in-depth phenomenological semi-structured individual interviews were conducted between January and February 2013. Data were analysed together with the field notes, using Tesch’s open coding protocol of qualitative data analysis. Lincoln and Guba’s four principles were used to ensure trustworthiness.Results: The themes that emerged from this study were that nurse educators experienced difficulty in recognising learners as individuals in a large class, using innovative pedagogical strategies, and managing a large class. These findings had a negative impact on meaningful teaching and learning as they interfered with an enabling learning environment.Recommendations: Nurse educators should be empowered with facilitative skills in order to effectively manage a large class and hence to achieve teaching and learning abilities.Conclusion: There is a need for nurse educators to finding alternative ways to overcome challenges associated with teaching in large classes and prepare learners to render individualised, caring and holistic nursing care to each unique patient in the healthcare setting.Keywords: Large class, Teaching, Learning; Hindrance

Previous research has found that scientific concepts can be meaningfully classified as descriptive (i.e., concepts such as predator and organism with directly observable exemplars) or theoretical (i.e., concepts such as atom and gene without directly observable exemplars). Previous research has also found that developing understanding of descriptive and theoretical concepts is linked to students' developmental levels, presumably because the procedural knowledge structures (i.e., reasoning patterns) that define developmental levels are needed for concept construction. The present study extends prior theory and research by postulating the existence of an intermediate class of concepts called hypothetical (i.e., concepts such as subduction and evolution with exemplars that cannot in practice be observed due to limits on the normal observational time frame). The hypothesis that three kinds of scientific concepts exist was tested by constructing and administering a test on concepts introduced in a college biology course. As predicted, descriptive concept questions were significantly easier than hypothetical concept questions, than were theoretical concept questions. Further, because concept construction presumably depends in part on developmental level, students at differing developmental levels (levels 3, 4, and 5, where level 5 is conceptualized as post-formal in which hypotheses involving unseen entities can be tested) were predicted to vary in the extent to which they succeeded on the concepts test. As predicted, a significant relationship (p < 0.001) was found between conceptual knowledge and developmental level. This result replicates previous research, and therefore provides additional support for the hypothesis that procedural knowledge skills associated with levels of intellectual development play an important role in declarative knowledge acquisition and in concept construction. The result also supports the hypothesis that intellectual development continues

Organizations in science and science education call for students to have a thorough understanding of the theory of evolution. Yet many high school biology teachers do not teach evolution and/or include creationism in their instruction (National Academy of Science, 1998). Historically, the controversy surrounding evolution has created tension for teachers. This case study explored the sociocultural influences related to teaching evolution in three Southern 10th-grade public high school biology classrooms. It also explored the socially and culturally embedded influences on teachers' instructional goals and personal perspectives toward evolution as well as modification of instruction when evolution is taught. Theoretically framed using symbolic interactionism and sociocultural theory, data were collected between October 2003 and April 2004 and included classroom observations two to three times per week, artifacts, and in-depth interviews of the participating teachers, their science department chairpersons, their students, and a Protestant minister. The classroom teachers were unaware of the focus of the study until after evolution was taught. The analysis used in this study was an inductive, interpretative approach that allowed exploration of the sociocultural influences that affect how teachers teach evolution. The sociocultural influences and the lived experiences of each teacher created a continuum for teaching evolution. One of the participating teachers who was heavily involved in the community and one of its fundamentalist churches elected to avoid teaching evolution. Another participating teacher at the same school integrated the theory of evolution in every unit. The third teacher who taught in another school elected to teach evolution in a superficial manner to avoid conflict. The data revealed that the participating teachers' sociocultural situatedness influenced their decisions and instruction on evolution. The influence of strong religious beliefs within

Full Text Available Visual impairment is a limitation that occurs in the sensory part of the vision, and can be classified as blindness, low vision or subnormal vision. The people with visually impaired have guaranteed rights to study in regular schools or special education schools. Therefore, a differentiated teaching is necessary for the learning of visually impaired students to happen effectively and ensure educational inclusion within the school. The aim of this study was to qualitatively analyze the teaching of Biological Sciences for the visually impaired in schools of the Distrito Federal, noting the institution, teachers and visually impaired students. The study was conducted using semi-structured interviews analyzed epistemologically. The results showed that: the institutions do not have adequate physical infrastructure; Biology teachers have no qualifications required; teachers of resource rooms are able to meet visually impaired students, even if resources are not sufficient, and the students do not understand all the benefits they could have. Therefore, it is necessary to adapt the teaching and learning materials to allow for a better education for visually impaired students and thus ensure appropriate learning for all students within the same educational institution.

Data relative to Pneumocystis pneumonia in sub-Saharan Africa are not well known. Weakness of the technical material and use of little sensitive biological tools of diagnosis are among the evoked reasons. The objective of this study is to update the data of the disease at the Fann Teaching Hospital in Dakar and to estimate biological methods used in diagnosis. A descriptive longitudinal study was carried out from January 5th, 2009 to October 31st, 2011 in the parasitology and mycology laboratory of the Fann Teaching Hospital in Dakar. The bronchoalveolar lavages received in the laboratory were examined microscopically for Pneumocystis jirovecii by indirect fluorescent assay or after Giemsa or toluidine blue O staining. One hundred and eighty-three bronchoalveolar lavages withdrawn from 183 patients were received in the laboratory. Sixteen were positive for P. jirovecii at 9% frequency. Four among these patients were HIV positive. Indirect fluorescent assay allowed finding of P. jirovecii among 16 patients while Giemsa staining discovered P. jirovecii only in a single patient. No case was diagnosed by toluidine blue O staining. Pneumocystis pneumonia in Parasitology and Mycology Laboratory of Fann Teaching Hospital at Dakar was mainly diagnosed among HIV patients.

This article provides a summary of the ideas discussed at the 2015 Annual Meeting of the Society for Integrative and Comparative Biology society-wide symposium on Leading Students and Faculty to Quantitative Biology through Active Learning. It also includes a brief review of the recent advancements in incorporating active learning approaches into quantitative biology classrooms. We begin with an overview of recent literature that shows that active learning can improve students' outcomes in Science, Technology, Engineering and Math Education disciplines. We then discuss how this approach can be particularly useful when teaching topics in quantitative biology. Next, we describe some of the recent initiatives to develop hands-on activities in quantitative biology at both the graduate and the undergraduate levels. Throughout the article we provide resources for educators who wish to integrate active learning and technology into their classrooms. © The Author 2015.

Full Text Available The structure and operating principle of semiconductor devices are a central topic in teaching electronics, both in universities and in two-year colleges. Teachers teaching this subject normally run into substantial difficulties stemming from the fact that a major part of the concepts and processes that are relevant to understanding these devices are abstract. In light of the advantages of multimedia in illustrating dynamic processes, the chapter covering the field effect transistor (FET has recently been taught through animation at a two-year college in Israel. The study presented here has examined, through quantitative tools, whether animation-based teaching of the FET had any effect on students’ achievements in the subject of basic electronic devices. Forty electronics students have participated in the study. Its findings indicate that in the short and long term alike, the achievements of students who studied the transistor through animation were significantly higher than those of their peers who studied it through a traditional method. Additionally, the effect size was very large.

Within a single research design, this investigation compared the effects of student and instructor cognitive mapping on student achievement and attitudes in introductory college biology for nonmajors. Subjects self-selected into either a Control Group that experienced no cognitive mapping, an Experimental Group 1 that experienced instructor cognitive mapping, or an Experimental Group 2 in which students constructed cognitive maps. Data were collected by a Students' Opinions of Teaching Poll and instructor prepared tests that included objective questions representing all levels of the cognitive domain. An ANCOVA revealed no significant differences in the academic achievement of students in the control and experimental groups. The academic performance of males and females was similar among all three groups of students and data confirmed a lack of interaction between gender and instructional strategy. This investigation confirmed that cognitive mapping will not disrupt a gender-neutral classroom environment. Students' opinions of teaching were overwhelmingly positive. A Kruskal Wallis analysis, followed by a nonparametric Tukey-type multiple comparison, revealed that students who experienced no mapping consistently rated the instructor with higher scores than did students who experienced instructor mapping. Students who cooperatively constructed cognitive maps reported the lowest scores on the opinion polls.

We conducted a study of 19 biology instructors participating in small, local groups at six research-intensive universities connected to the Automated Analysis of Constructed Response (AACR) project (www.msu.edu/∼aacr). Our aim was to uncover participants' motivation to persist in a long-term teaching professional development effort, a topic that is understudied in discipline-based educational research. We interviewed each participant twice over a 2-year period and conducted qualitative analyses on the data, using expectancy-value theory as a framework for considering motivation. Our analyses revealed that motivation among instructors was high due to their enjoyment of the AACR groups. The high level of motivation is further explained by the fact that AACR groups facilitated instructor involvement with the larger AACR project. We also found that group dynamics encouraged persistence; instructors thought they might never talk with colleagues about teaching in the absence of AACR groups; and groups were perceived to have a low-enough time requirement to warrant sustained involvement. We conclude that instructors have persisted in AACR groups because the groups provided great value with limited cost. The characterization of instructor experiences described here can contribute to a better understanding of faculty needs in teaching professional development. © 2017 J. S. McCourt et al.

In this paper, I explain variation in the adoption of student-centred teaching practices among college faculty members in a program designed to promote K-20 instructional reform. I analyze data from a qualitative study of a Math and Science Partnership in order to understand why some faculty members had undergone extensive changes to their practices whereas others had not, even though both groups had demonstrated changes in their beliefs. Findings show that when collective identities focused on reform become more salient than the role identities associated with their teaching positions, faculty members are able to persist through the loss of self-efficacy that results from struggles with new student-centred practices. This study demonstrates how professional communities can enhance "collective efficacy", thereby affecting whether the cognitive dissonance that accompanies professional development leads to instructional change rather than disengagement from reform initiatives.

Structural molecular biology is now becoming part of high school science curriculum thus posing a challenge for teachers who need to convey three-dimensional (3D) structures with conventional text and pictures. In many cases even interactive computer graphics does not go far enough to address these challenges. We have developed a flexible model of the polypeptide backbone using 3D printing technology. With this model we have produced a polypeptide assembly kit to create an idealized model of the Triosephosphate isomerase mutase enzyme (TIM), which forms a structure known as TIM barrel. This kit has been used in a laboratory practical where students perform a step-by-step investigation into the nature of protein folding, starting with the handedness of amino acids to the formation of secondary and tertiary structure. Based on the classroom evidence we collected, we conclude that these models are valuable and inexpensive resource for teaching structural molecular biology. Copyright © 2017 Elsevier Ltd.

Studies indicate that many teachers have negative beliefs about science, which translates into low teacher efficacy, resulting in avoidance of science teaching or in ineffective science teaching behaviors. Highly efficacious teachers have been found to be more likely to use inquiry and student-centered teaching strategies, while teachers with a low sense of science-teaching efficacy are more likely to use teacher-directed strategies, such as didactic lectures and reading from the textbook (Czemiak, 1990). The purpose of this study was to investigate preservice science teachers' science-teaching self-efficacy changes and their correlation to teaching environment factors during the student teaching semester. Moreover, it explains how teaching environment factors and preservice teachers' science-teaching self-efficacy beliefs may relate to their use of teaching strategies in the science classroom during their student teacher training at teachers' colleges in Saudi Arabia. The population of this study is consisted of 184 middle and elementary preservice science teachers who were doing their student teaching at nine teachers' colleges (i.e., teachers' colleges of Riyadh, Dammam, Alrras, Almadinah, Alihsa, Jeddah, Makah, Altaief, and Abha) in Saudi Arabia during the spring semester of 2005. Three instruments were used to collect data for this study: (1) to measure science teaching self-efficacy, the researcher adapted the Science Teaching Efficacy Belief Instrument form B designed specifically for preservice teachers (STEBI-B); (2) to measure the school environment, the researcher adapted the Organizational Health Inventory (OHI), developed by Hoy, Tarter & Kottkamp (1991); and (3) to measure the type and frequency of instructional strategies that preservice science teachers use in the classroom, the researcher adapted the teaching practice subscale from The Local Systemic Change through Teacher Enhancement Science K-8 Teacher Questionnaire (Horizon Research, Inc., 2000
Full Text Available Facing the current situation that Chinese students are poor in English productive ability, the mode of only English-medium teaching is put forward to completely improve students’ English abilities and comprehensive competence by creating second language acquisition atmosphere. Since few studies have been conducted on students’ attitudes toward only English-medium teaching in ELT classrooms especially from the perspective of students themselves, this paper, through questionnaires and interviews, focuses on students’ attitudes to figure out their preferences, evaluations and suggestions of teaching modes, and further discusses the practical application of only English-medium teaching in EFL classrooms from five respects: teaching purpose, course design, teacher’ qualification, students’ language level and teaching effect. It is concluded that only English-medium teaching is not of popularity among students giving their own English levels and the advancement of only English-medium teaching quality depends on the qualified teachers and suitable courses. Keywords: English teaching, Teaching effect, Teacher qualification, Students’ language level, Course design
Background Failure to plan a pregnancy can adversely affect the health of the family as a whole. High parity is related to increased maternal, perinatal and infant deaths and is associated with nutritional problems of both mother and child. Hence, good knowledge, attitude and practice of family planning among women are important. This study is aimed to determine the knowledge, attitude and practice of contraception among the postpartum women attending Kathmandu Medical College Teaching Hospital. Objective To determine the knowledge, attitude and the practice of various contraceptive methods among the postpartum women. Method A cross-sectional observational study was conducted in the department of Obstetrics and Gynecology on 400 postpartum women (within 42 days of delivery) who delivered and came for follow-up in this institution. All the postnatal women were interviewed with pre-designed questionnaire and information on sociodemographic variable, awareness and knowledge of various contraceptive methods, previous and current use of family planning methods, source of information, utilization and reasons for use/non-use of family planning methods were obtained. Data collected were entered and analyzed using SPSS 20. The results were presented as percentages, means, tables and charts. Result Majority of the participants 363 (90.8%) were aware of contraceptive usage. Amongst 60.5% of women who had previously used contraception, OCPs were the commonest one. Maximum number of participants (60.35%) had used modern contraceptives in the past. The most common source of information on contraception was media (55.7%). The reason of using contraception was spacing between the subsequent pregnancies, while the most common reason of discontinuation or not willing to use family planning methods was husband being abroad, fear of side effects and not knowing which contraceptives to use. Conclusion The contraceptive awareness and knowledge among the postpartum women was high but

Cooperative learning allows individuals with varying abilities to work alongside their peers. Students are placed into achievement levels based on placement test scores. The Regular College Preparatory (RCP) level is a score of 59% or lower and Academic College Preparatory (ACP) level is a score of 60-92% on the placement test. The purpose of this study was to obtain 9th grade RCP students' perceptions of the student teams achievement divisions (STAD) approach which allows each member of a team to have a defined role in group work. The research questions addressed 9 th grade RCP students' perceptions of integrated STAD teams. Qualitative data from 6 RCP participants were collected from interviews and observations. Data were analyzed using typological analysis by creating codes and categories. Findings indicated that RCP students retained more content and enhanced their skills in communication, critical thinking, and problem solving. Teachers need to serve as guides to monitor motivation and enhance peer interaction. School administrators are advised to provide professional development opportunities allowing educators to learn how to incorporate cooperation for optimal student learning communication, negotiation, and problem solving.

This study is an investigation into the science literacy of college genetics students who were given a modified curriculum to address specific teaching and learning problems from a previous class. This study arose out of an interest by the professor and researcher to determine how well students in the class Human Genetics in the 21st Century responded to a reorganized curriculum to address misconceptions that were prevalent after direct instruction in the previous year's class. One of the components to the revised curriculum was the addition of a multimodal representation requirement as part of their normal writing assignments. How well students performed in these writing assignments and the relationship they had to student learning the rest of the class formed the principle research interest of this study. Improving science literacy has been a consistent goal of science educators and policy makers for over 50 years (DeBoer, 2000). This study uses the conceptualization of Norris and Phillips (2003) in which science literacy can be organized into both the fundamental sense (reading and writing) and the derived sense (experience and knowledge) of science literacy. The fundamental sense of science literacy was investigated in the students' ability to understand and use multimodal representations as part of their homework writing assignments. The derived sense of science literacy was investigated in how well students were able to apply their previous learning to class assessments found in quizzes and exams. This study uses a mixed-methods correlational design to investigate the relationship that existed between students' writing assignment experiences connected to multimodal representations and their academic performance in classroom assessments. Multimodal representations are pervasive in science literature and communication. These are the figures, diagrams, tables, pictures, mathematical equations, and any other form of content in which scientists and science

We represent several generations of biology educators – with teaching experiences beginning in the 1940s and continuing to the present, from elementary school to graduate-level programs. We find the vast array of subjects that biology teachers can now cover both thrilling and mind-boggling. Depending on the grade level, units exist that focus on neurobiology, forensics, DNA analysis, biotechnology, marine biology, and a host of other topics.Although science teachers cover a potpourri of advanced topics, we must ask ourselves – no matter our biology-teaching responsibilities – how well we are teaching carrying capacity, one of the most fundamental biological concepts for our society, knowledge of which becomes more important every day. As biology teachers, most of you know that carrying capacity is defined as the maximum population an environment can sustain, given the amounts of food, habitat, and other resources available. Every environment – from your goldfish bowl to the local forest to planet Earth – can only sustain a set number (weight) of a particular species, based on available resources and space. Currently, most science classes teach …

This article presents a selective review of best practices for the psychiatric care of college student populations. It describes psychiatric advances in evidence-based practice for college students and offers a brief compendium for college health practitioners. College mental health services are delivered in a specialized milieu, designed to address many of the unique needs of college students and to support their successful scholastic advancement and graduation. Practical steps for implementing these best practices within the college community setting are identified, with a focus on the initial student evaluation, risk assessment, treatment planning and goal setting, and steps to optimize academic functioning during psychopharmacologic and nonpharmacologic treatment. At the center of these practices is the use of a collaborative team and psychoeducation that engages students to actively learn about their mental health. By applying common sense and evidence-based practices within interdisciplinary and student-centered services, college communities can effectively meet the mental health needs of their students and empower them to reach their educational goals.

Purpose. The purpose of this study was to identify, according to the Productivity Environment Preference Survey (PEPS) instrument, which learning-style domains (environmental, emotional, sociological, and physiological) were favored among Latino/Hispanic community college students enrolled in introductory biology classes in a large, urban community college. An additional purpose of this study was to determine whether statistically significant differences existed between the learning-style preferences and the demographic variables of age, gender, number of prior science courses, second language learner status, and earlier exposure to scientific information. Methodology. The study design was descriptive and ex post facto. The sample consisted of a total of 332 Latino/Hispanic students enrolled in General Biology 3. Major findings. The study revealed that Latino/Hispanic students enrolled in introductory biology at a large urban community college scored higher for the learning preference element of structure. Students twenty-five years and older scored higher for the learning preference elements of light, design, persistence, responsibility, and morning time (p English language learners and those who learned English as their primary language (p <= 0.05). Students who frequently read science articles scored higher for the elements of motivation, persistence, responsibility, and tactile (p <= 0.05). Conclusions and recommendations. The conclusions were that Latino/Hispanic students need detailed guidance and clearly stated course objectives. The recommendations were: (1) College professors, counselors, and administrators must become aware of the Dunn learning-style model and instruments and on recent learning-style research articles on ethnically diverse groups of adult learners; and (2) Instructors should plan their instruction to incorporate the learning-style preferences of their students.

Full Text Available INTRODUCTION: Currently students grow up in a world of digital tools that allow you to connect instantly with the world. At the same time, teachers face several challenges to increase student interest and learning efficiency. One such challenge is the pedagogical commitment of the density of biochemistry and cell biology contents, producing a conflict scenario, between meeting content and maintain the class quality. OBJECTIVES: From this perspective, this study aimed to evaluate the learning biochemistry and cell biology contents in high school classes of IFRN, using collaborative and digital tools in the Moodle. MATERIAL AND METHODS: The contents were offered using various tools such as video lectures, forums, questionnaires, portfolios, glossaries and electronic books. Then these tools were evaluated using an electronic form. In addition to the tools, we evaluated the platform interaction, the performance of activities and the content gamification. RESULTS: The quantitative results revealed directly proportional relationship of the interaction of Moodle with the performance of activities. The content gamification was also assessed positively, with 61% of students considered good, very good or excellent. The best evaluated tools were video lectures, with 31% preference, and questionnaires, with 24%; followed by electronic book, with 10%, and portfolio, with 5.5%. The other tools totaled 30% of the preference. Qualitative results revealed an educational gain of content, because the student lived the experience of teaching and learning collaboratively. In addition, these tools decreased conflicts between content and schedule. CONCLUSION: Thus, the use of information and communication technology (ICT in a collaborative learning provides relevant results, bringing the reality of the world connected to the classroom. In addition, it assists in defining the content and creative development of a strategy for the construction of the concepts applied
Scientific attitude is need of today's society for peaceful and meaningful living of every person in a multicultural world. A case study was conducted at the Faculty of Teacher Training and Education, University of Riau, Pekanbaru in order to describe the scientific attitude that shaped by research-based teaching (RBT). Eighteen students of English for Biology bilingual program were selected from 88 regular students as a subject of the study. RBT designed consists of 9 steps: 1) field observations, 2) developing research proposals, 3) research proposal seminar, 4) field data collecting, 5) data analyzing & ilustrating, 6) writing research papers, 7) preparing power point slides, 8) creating a scientific poster, 9) seminar & poster session. Data were collected by using check list observation instuments during 14 weeks (course sessions), then analyzed by using descriptive-quantitative method. The results showed that RBT were able to shape critical-mindedness, suspended judgement, respect for evidence, honesty, objectivity, and questioning attitude as well as tolerance of uncertainty. These attitudes which shaped were varies according to every steps of learning activities. It's seems that the preparation of scientific posters and research seminar quite good in shaping the critical-mindedness, suspended judgment, respect for evidence, honesty, objectivity, and questioning attitude, as well as tolerance of uncertainty. In conclusion, the application of research-based teaching through the English for Biology courses could shape the students scientific attitudes. However, the consistency of the appearance of a scientific attitude in every stage of Biology-based RBT learning process need more intensive and critical assessment.

This study was aimed at determining the perception of the medical students of a relatively new medical school in Nigeria about the teaching of Pharmacology, the best way of learning and retaining the subject. Suggestions on the ways of making pharmacology more interesting to them were also sought. A total of forty eight 400 level medical students of the Lagos State University College of Medicine (LASUCOM), who were due to write 2nd Professional M.B; B.S degree examinations in 2007 and 26 successful older students that had passed the 2nd Professional M.B; B.S degree examinations in 2006, were interviewed with a structured questionnaire. Some of the questions were close-ended but the ones related to suggestion on impaired teaching of the subject were open-ended. The pharmacology lecturers were also interviewed with another questionnaire, different from the one used in interviewing the students, to assess their views on the non-inclusion of clinical pharmacology topics to the curriculum and to suggest ways of improving the teaching of the subject. Sixteen (41.02%) respondents and 26 (92.86%) successful older students wanted audiovisual aids teaching and inclusion of clinically oriented pharmacology lectures. Fourteen (35.89%) respondents respectively and all the successful older students wanted seminars and group discussions introduced into their programme. Over half (58.97%) of the respondents and all the successful older students wanted case studies and treatment as part of the regular teaching schedule, 20 (51.28%) respondents and 20 (76.92%) successful older students preferred inclusion of clinical pharmacology. Most of the students (respondents and older successful students) felt that special topics in clinical pharmacology should be taught both in the lectures and practical. Medical students are very willing to learn pharmacology from both clinical and therapeutic angles that encompass both theoretical and practical approaches. It is therefore imperative to

Developing human capital in nuclear with required nuclear background and professional qualifications is necessary to support the implementation of nuclear power projects in the near future. Sufficient educational and training skills are required to ensure that the human resources needed by the nuclear power industry meets its high standard. The Government of Malaysia has made the decision to include nuclear as one of the electricity generation option for the country, post 2020 in order to cater for the increasing energy demands of the country as well as to reduce CO2 emission. The commitment by the government has been made clearer with the inclusion of the development of first NPP by 2021 in the Economic Transformation Program (ETP) which was launched by the government in October 2010. The In tandem with the government initiative to promote nuclear energy, Center for Nuclear Energy, College of Engineering, Universiti Tenaga Nasional (UNITEN) is taking the responsibility in developing human capital in the area of nuclear power and technology. In the beginning, the College of Engineering has offered the Introduction to Nuclear Technology course as a technical elective course for all undergraduate engineering students. Gradually, other nuclear technical elective courses are offered such as Nuclear Policy, Security and Safeguards, Introduction to Nuclear Engineering, Radiation Detection and Nuclear Instrumentation, Introduction to Reactor Physics, Radiation Safety and Waste Management, and Nuclear Thermal-hydraulics. In addition, another course Advancement in Nuclear Energy is offered as one of the postgraduate elective courses. To enhance the capability of teaching staffs in nuclear areas at UNITEN, several junior lecturers are sent to pursue their postgraduate studies in the Republic of Korea, United States and the United Kingdom, while the others are participating in short courses and workshops in nuclear that are conducted locally and abroad.

Previous experiments have shown that college students benefit when they understand that challenges in the transition to college are common and improvable and, thus, that early struggles need not portend a permanent lack of belonging or potential. Could such an approach-called a lay theory intervention-be effective before college matriculation? Could this strategy reduce a portion of racial, ethnic, and socioeconomic achievement gaps for entire institutions? Three double-blind experiments tested this possibility. Ninety percent of first-year college students from three institutions were randomly assigned to complete single-session, online lay theory or control materials before matriculation (n > 9,500). The lay theory interventions raised first-year full-time college enrollment among students from socially and economically disadvantaged backgrounds exiting a high-performing charter high school network or entering a public flagship university (experiments 1 and 2) and, at a selective private university, raised disadvantaged students' cumulative first-year grade point average (experiment 3). These gains correspond to 31-40% reductions of the raw (unadjusted) institutional achievement gaps between students from disadvantaged and nondisadvantaged backgrounds at those institutions. Further, follow-up surveys suggest that the interventions improved disadvantaged students' overall college experiences, promoting use of student support services and the development of friendship networks and mentor relationships. This research therefore provides a basis for further tests of the generalizability of preparatory lay theories interventions and of their potential to reduce social inequality and improve other major life transitions.
On the occasion of the 250th anniversary of the foundation of the astronomical observatory at the college and seminary of Nagyszombat in 1755, it may be of interest to say something about the colleges of the Society of Jesus. The presence of the Jesuits there was brief, only two decades, as under the pressure of various external forces, the Jesuit Order was suppressed by Pope Clement XIV with the bull Dominus ac Redemptor on 23 July 1773. All the colleges that the Society had been running successfully all over the world either were closed, taken over by the governments, or given to the local bishops. Shortly after the Jesuits left the college of Nagyszombat, the king transferred it to Buda, where it gave rise to modern institutions of higher education derived. When Pope Pius VII returned to Rome after the Napoleonic wars, one of the first things he did was to reestablish the Society of Jesus in 1814. Old Jesuits, survivors of so many disgraces, joined younger Jesuits from Russia and Poland where in fact the order had never been suppressed. The most important of the Jesuit colleges, the Collegium Romanum in Rome, was given back to the Society of Jesus in 1823. Many other colleges were lost forever, but new ones were founded to continue the Society's previous successful activity.

The body of research work presented in this dissertation integrates critical ethnography with video and conversation analyses in order to provide ways to articulate and understand the complexities associated with social life enactment as it unfolds during cogenerative dialogues and in the science classroom as the teacher and her students engage in science teaching and learning. The primary goal is to improve the teaching and learning of science in an urban science classroom at a public high school in Philadelphia, Pennsylvania. In order to understand what is going on in the classroom and why, I worked with a female science teacher who identify as an African-American and her culturally diversified students in a biology class to examine teacher's and students' conscious and unconscious patterned actions, (i.e., classroom practices, that structure teaching and learning in the classroom. It is my belief that to improve science teaching and learning in the classroom, it is salient to improve science teacher's practices as a precursor to transforming students' practices. In order to ameliorate breaches in the fluency of encounters in the classroom, the teacher and her students need to establish and sustain critical, collaborative and collective conversations through cogen. I employ theoretical lenses of cultural sociology that I triangulate with sociology of emotions and critical pedagogy. I focus on culture as schemas and associated practices layered with the triple dialectics of agency, passivity and structure as new or hybridized/interstitial cultures that are produced get enacted in the science classroom to transform teacher's and her students' encounters with each other. The salient implication is that since encounters are imbued with emotions, teacher and her students learn to generate positive emotional energy during cogen that gets reproduced and transformed in the science classroom. Positive emotional energy creates resources that help to initiate and sustain
Full Text Available Agricultural higher education institutions have a significant role in development of the agriculture sector and the effectiveness of higher education is dependent on the quality of teaching offered by its faculty members. The purpose of this study was to determine and classify factors related to teaching quality by members of a scientific board. The method of evaluation for this research was by evaluation of data from a descriptive survey taken with a researcher made questionnaire. The target population of the study consisted of 256 faculty members in agricultural colleges in Tehran University. A sample of 100 staff was selected through a randomized multi-stage sampling method based on the Koukran formula. The questionnaire, used as the research tool, was verified by a panel of experts. The reliability of the questionnaire was verified through calculating the Crookback Alpha coefficient equal to 0/86 following a pilot study. Data was analyzed through SPSS15/Win and results of the explorative factor analysis revealed that five components explained 74/82% of the total variance. These factors were as follows; (1 lesson plan (19.52%, (2 teaching skill (17.97%, (3 communication skills (17.93%, (4 expertise related to lesson content (10.59%, and (5 individual capabilities of members (9.15% respectively.

Student-centered approaches to learning are aligned with the Constructivist Model and have been the focus of much recent science education research in the United States. It is based on the premise that students learn better when they are actively engaged and given the opportunity to construct their own knowledge. In addition, the search continues for effective science curricular and pedagogical approaches that will provide adequate understanding of the nature of science and development of positive attitudes. This study investigated the effectiveness of the scientific inquiry approach, which is a student-centered style of teaching, in improving students' attitudes and understanding of the nature of science. The scientific inquiry approach was used in the teaching of Natural Science in a Philippine university. Pre- and post-surveys on attitude and views about science were administered to 767 first year college students enrolled in the course. The results of the surveys revealed significant differences in both students' views and their attitudes before and after instruction. The overall trend of respondents' answers was changed from a mixed-folk (unscientific) direction to a mixed-expert (scientific) direction. Thus, the study concludes that the scientific inquiry style of teaching makes a significant impact in changing or improving students' attitudes and understanding about the nature of science. This study also showed a positive correlation between students' views and their attitudes toward science.

Through the administration of the Geoscience Concept Inventory (GCI) in over 50 introductory college-level geosciences courses nationwide, we identified little to no pre- to post-test gain on many of the GCI questions. Although it may seem reasonable to attribute these results to the entrenchment of ideas in this population of students, a closer look at individual matched pre- and post-tests shows that student ideas about the Earth are extremely mobile rather than entrenched. For those individual GCI questions that show low or no gain from pre- to post-test, individual students are typically switching between wrong answers, rather than holding on to one particular alternative conception. Of the 21 GCI questions that showed a normalized gain of definition of a tectonic plate. These results have implications for the teaching of introductory college-level geosciences courses. We suggest that students may have difficulty settling on a correct geosciences conception because of the shaky supporting-science underpinnings upon which these geosciences concepts are built. An important question stemming from these results is "when does learning occur in college-level courses?". Given that students in most introductory geosciences courses show little or no overall gain over the course of a semester, when do our geology majors gain a firm conceptual understanding of our fundamental geosciences topics, what role does the introductory course play in their learning, and are there strategies that can be employed in introductory courses to enhance learning for those students who will only take one college-level geosciences course? In light of findings available from GCI and other research, we suggest that longitudinal studies of learning in the geosciences are needed for time periods longer than a semester, and that more attention be paid to when conceptual change occurs for our majors.

Self-efficacy theory was first introduced in a seminal article by Albert Bandura in 1977 entitled "Self-efficacy: Toward a unifying theory of behavioral change". Since its original introduction, self-efficacy has been a major focus of academic performance, anxiety, career development, and teacher retention research. Self-efficacy can be defined as the belief an individual possesses about their ability to perform a given task. Bandura proposed that self-efficacy should be measured at the highest level of specificity due to the fact that different people are efficacious in different areas. Interested in students' efficacy toward biology, Ebert-May, Baldwin, & Allred (1997) created and validated a survey to measure students' biology self-efficacy. Their survey was modeled after the guidelines for science literacy, and loaded to three sub-factors; methods of biology, generalization to other science courses, and application of the concepts. As self-efficacy theory has been related to effort expenditure and persistence (Bandura, 1977; 1997), one might think it would have some effect on students' attitudes toward the topic at hand. The current research investigated what changes in biology self-efficacy occurred after an introductory biology course with an inquiry based laboratory learning environment. In addition, changes in students' attitudes towards science were explored and how self-efficacy might affect them.

Although frequently coexistent, we know little about the interactions among research, teaching and learning in higher education. This study examines the preferences of second and third year dental students for questions that require a research-based deep approach or questions that require a straightforward didactic approach. A questionnaire was designed to evaluate the opinion of 114 students who took part in the Oral Biology course. 56 second year students (75%) responded while 58 (84%) of third year students responded. Questions that required an interpretive approach were found to be most appealing by 70.2% of all students. Questions which required a regurgitative approach were favoured by 11.6% of students. No significant differences were found when the sample was broken down by country of origin, year of study or gender, suggesting that dental students preferred research-based learning rather than superficial didactic learning.
Previous work has established that a narrated animation is more effective at communicating a complex biological process (signal transduction) than the equivalent graphic with figure legend. To my knowledge, no study has been done in any subject area on the effectiveness of animations versus graphics in the long-term retention of information, a primary and critical issue in studies of teaching and learning. In this study, involving 393 student responses, three different animations and two graphics—one with and one lacking a legend—were used to determine the long-term retention of information. The results show that students retain more information 21 d after viewing an animation without narration compared with an equivalent graphic whether or not that graphic had a legend. Students' comments provide additional insight into the value of animations in the pedagogical process, and suggestions for future work are proposed. PMID:17785404
Full Text Available This paper documents our experience using declarative languages to give secondary school students a first taste of Computer Science. The course aims to teach students a bit about programming in Prolog, but also exposes them to important Computer Science concepts, such as unification or searching strategies. Using Haskell's Snap Framework in combination with our own NanoProlog library, we have developed a web application to teach this course.

This easy-to-read guide gives educators the kind of clear explanations, examples, and strategies they need to feel comfortable teaching the CCSS, an
This study investigated undergraduate students' attitudes toward science and science teaching who were majoring in science education at four-year teachers colleges in Turkey. Furthermore, the study examined pre-service Turkish science teachers' attitudes toward science and science teaching based on genders, class levels, teachers colleges, and several socio-demographic factors. The subjects for this study were 309 female and 303 male pre-service Turkish science teachers, who were freshmen, sophomores, juniors, and seniors, from teachers colleges of Ataturk, Dokuz Eylul, Gazi, and Karadeniz Technical Universities in Turkey during the 1998 spring semester. The instrument used in this study was "Science Teaching Attitude Scale-II" (STAS-II) developed by Moore (1973) and revised by Moore and Foy (1997). The reliability coefficient of the Turkish translation of STAS-II was found to be .795 using test-retest method. Three-way analysis of variance (ANOVA) and multiple regression analysis were the statistical techniques utilized to test the null hypotheses of the study. The results of the study showed that all of the subjects have positive attitudes toward science and science teaching. There was a statistically significant mean difference between class levels on attitudes of pre-service Turkish science teachers toward science and science teaching. This was primarily due to a statistically higher attitudinal mean of juniors than that of freshmen using three-way ANOVA and Tukey tests. However, when data were analyzed according to gender and teachers colleges, attitudes of pre-service Turkish science teachers toward science and science teaching did not indicate statistically significant mean differences. The subjects of families having higher level incomes had statistically significant higher mean on attitudes toward science and science teaching than other subjects. Therefore, the uniqueness of a nationwide science curriculum and the unification of the education system may

In this study, we used a case study approach to obtain an in-depth understanding of the change process of two university instructors who were involved with redesigning a biology course. Given the hesitancy of many biology instructors to adopt evidence-based, learner-centered teaching methods, there is a critical need to understand how biology instructors transition from teacher-centered (i.e., lecture-based) instruction to teaching that focuses on the students. Using the innovation-decision model for change, we explored the motivation, decision-making, and reflective processes of the two instructors through two consecutive, large-enrollment biology course offerings. Our data reveal that the change process is somewhat unpredictable, requiring patience and persistence during inevitable challenges that arise for instructors and students. For example, the change process requires instructors to adopt a teacher-facilitator role as opposed to an expert role, to cover fewer course topics in greater depth, and to give students a degree of control over their own learning. Students must adjust to taking responsibility for their own learning, working collaboratively, and relinquishing the anonymity afforded by lecture-based teaching. We suggest implications for instructors wishing to change their teaching and administrators wishing to encourage adoption of learner-centered teaching at their institutions. © 2016 G.

Full Text Available Electrical engineering staff (reorganized to Electrical and Computer engineering in 2004 has taught electrical engineering students for mathematics classes in Wakayama National College of Technology (WNCT in Japan from 2007. Effects of the mathematics classes by the electrical engineering staff were evaluated by using the results of the mathematics placement tests. The results of the tests are compared with averages of other National Colleges of Technology in Japan and other divisions of WNCT. As a result, an ability of electrical engineering students for mathematics improved dramatically with increasing the ratio of mathematics classes by the electrical engineering staff. It should seem that these good results were achieved by eagerness and strong motivation of the staff with electrical specialty for improving the ability of their division's students. The reasons for the improvement are discussed and the unique class of mathematics for college of technology is also introduced.

Full Text Available There are very few studies concerning the importance of teaching methods in biology education and environmental education including outdoor education for promoting sustainability at the levels of primary and secondary schools and pre-service teacher education. The material was selected using special keywords from biology and sustainable education in several scientific databases. The article provides an overview of 24 selected articles published in peer-reviewed scientific journals from 2006–2016. The data was analyzed using qualitative content analysis. Altogether, 16 journals were selected and 24 articles were analyzed in detail. The foci of the analyses were teaching methods, learning environments, knowledge and thinking skills, psychomotor skills, emotions and attitudes, and evaluation methods. Additionally, features of good methods were investigated and their implications for teaching were emphasized. In total, 22 different teaching methods were found to improve sustainability education in different ways. The most emphasized teaching methods were those in which students worked in groups and participated actively in learning processes. Research points toward the value of teaching methods that provide a good introduction and supportive guidelines and include active participation and interactivity.

Undergraduate biology students are required to learn, understand and apply a variety of cellular and molecular biology concepts and techniques in preparation for biomedical, graduate and professional programs or careers in science. To address this, a simple laboratory module was devised to teach the concepts of cell division, cellular communication and cancer through the application of animal cell culture techniques. Here the mouse mammary tumor (MMT) cell line is used to model for breast cancer. Students learn to grow and characterize these animal cells in culture and test the effects of traditional and non-traditional chemotherapy agents on cell proliferation. Specifically, students determine the optimal cell concentration for plating and growing cells, learn how to prepare and dilute drug solutions, identify the best dosage and treatment time course of the antiproliferative agents, and ascertain the rate of cell death in response to various treatments. The module employs both a standard cell counting technique using a hemocytometer and a novel cell counting method using microscopy software. The experimental procedure lends to open-ended inquiry as students can modify critical steps of the protocol, including testing homeopathic agents and over-the-counter drugs. In short, this lab module requires students to use the scientific process to apply their knowledge of the cell cycle, cellular signaling pathways, cancer and modes of treatment, all while developing an array of laboratory skills including cell culture and analysis of experimental data not routinely taught in the undergraduate classroom.

The ability to interpret and reason from Tree of Life (ToL) diagrams has become a vital component of science literacy in the 21st century. This article reports on the effectiveness of a research-based curriculum, including an instructional booklet, laboratory, and lectures, to teach the fundamentals of such tree thinking in an introductory biology class for science majors. We present the results of a study involving 117 undergraduates who received either our new research-based tree-thinking curriculum or business-as-usual instruction. We found greater gains in tree-thinking abilities for the experimental instruction group than for the business-as-usual group, as measured by performance on our novel assessment instrument. This was a medium size effect. These gains were observed on an unannounced test that was administered ∼5-6 weeks after the primary instruction in tree thinking. The nature of students' postinstruction difficulties with tree thinking suggests that the critical underlying concept for acquiring expert-level competence in this area is understanding that any specific phylogenetic tree is a subset of the complete, unimaginably large ToL. © 2016 L.

The main research question of this study was: What gaps in biochemical understanding are revealed by a range of university introductory biology students as they work through a critically acclaimed multimedia program on photosynthesis, and what are the corresponding implications for elaboration of the Ausubel-Novak-Gowin Learning Theory (ANG, now Human Constructivism)? Twelve students, mixed for ability, gender and ethnicity, were recruited from two sections of "Bio 101." Before and after instruction in photosynthesis, in-depth clinical interviews were conducted during which participants completed a range of cognitive tasks such as sorting, concept mapping, explaining and predicting. Some tasks involved interacting with a computer simulation of photosynthesis. This study primarily employed qualitative case study and verbal analysis methods. Verbal analysis of the clinical interviews revealed numerous gaps that were categorized into typologies. The two major categories were propositional gaps and processing gaps. Propositional gaps were evident in development of participants' concepts, links and constructs. Significant among these were conceptual distance gaps and continuity of matter gaps. Gaps such as convention gaps and relative significance gaps seem to be due to naivete in the discipline. Processing gaps included gaps in graphic decoding skills and relevant cognitive habits such as self-monitoring and consulting prior knowledge. Although the gaps were easier to detect and isolate with the above-average participants, all participants showed evidence of at least some of these gaps. Since some gaps are not unexpected at all but the highest literacy levels, not all the gaps identified are to be considered deficiencies. The gaps identified support the attention given by ANG theorists to the role of prior knowledge and metacognition as well as the value of graphic organizers in knowledge construction. In addition, this study revealed numerous gaps in graphic decoding

Full Text Available Many universities have introduced Humanities subjects into the engineering streams in tune with trends practiced globally. Engineers need to inculcate the spirit of humanities to acquire team spirit, critical thinking abilities and also problem-solving abilities for career advancement. Language skills empower engineers to face future challenges globally. In India also, Communicative English and Business English/ Professional English have been integrated into the Humanities stream of undergraduate programs in all Engineering colleges. Under this background, this empirical study examines the problems related to syllabus designed in the existing curricula of English language through questionnaire survey which was administered to 770 students of 20 engineering colleges. Ten items questionnaire objectively aimed to analyze three different aspects of the course designed for engineers. Firstly, to find out how the implementation of the syllabus matches the language learning needs of the students of the digital age. Secondly, to examine the teaching methodologies of four language skills of listening, speaking, reading and writing and finally to investigate how far the students preferred lab classes to theory classes. On the basis of the responses elicited, the aspects related to their immediate need of a learner centered curriculum are represented through graphical data for better interpretation. The research, thus, aimed at throwing light on the strengths and weaknesses of the existing system and the need to envisage a paradigm shift for preparing global engineers in the context of fast emerging situations around the world.
In the midst of a teacher shortage no field suffers more than physics. Half of our secondary physics teachers have less than a minor in physics. Meanwhile half of our future teachers start out at two-year colleges with physicists on staff. The opportunity for community colleges to have an impact on K-12 teaching is tremendous. Project TEACH has been honored as an outstanding teacher preparation program. It is a collaboration of colleges and K-12 schools dedicated to the improvement of teacher preparation, especially in science and math. Based at Green River Community College, Project TEACH unites certification institutions, community colleges, and K-12 school districts in the pre-service and in-service training of teachers. Activities of Project TEACH include recruitment and advising of future teachers, field experience for education students, creation of pre-teaching and para-educator degrees, tutoring from elementary school through college, in-service courses for current teachers, and special math and science courses aimed at future teachers. The yearlong interdisciplinary science sequence blends chemistry, physics, geology, and biology in a hands-on inquiry-based environment. The yearlong math sequence covers arithmetic, algebra, geometry, and probability with inquiry-based pedagogy. The programs developed by Project TEACH are being disseminated to colleges across Washington State and beyond.
Full Text Available This study is part of a research project that aims to characterize the epistemological, psychological and didactic presuppositions of science teachers (Biology, Physics, Chemistry that implement Computational Modeling and Simulation (CMS activities as a part of their teaching practice. We present here a synthesis of a literature review on the subject, evidencing how in the last two decades this form of computer usage for science teaching has boomed in disciplines such as Physics and Chemistry, but in a lesser degree in Biology. Additionally, in the works that dwell on the use of CMS in Biology, we identified a lack of theoretical bases that support their epistemological, psychological and/or didactic postures. Accordingly, this generates significant considerations for the fields of research and teacher instruction in Science Education.

Full Text Available This study aims to investigate the student satisfaction with the Online English Language courses piloted for the first time at a Vocational College in a remote town located in the north-west of Turkey in 2014-2015 educational year. These courses were designed with a format of face-to-face testing and online delivery of course materials. Data were collected from students both quantitatively and qualitatively using a survey which included seven likert scale attitude questions and two open-ended questions where they had to express their opinions about either face-to-face or online courses of which they thought was more advantageous and relevant for them. Twenty three female and a hundred and eighty four male students attending ten different departments, aged mostly eighteen and nineteen years participated in our study. Quantitative data from the students indicate that while 52% of the whole participants thought that online teaching of English as a foreign language was not useful for them at all, just 6% of the students declared that the online teaching system was very useful. To the question whether they preferred online or face-to-face learning, quite surprisingly, 82% of the participants declared that they preferred face-to-face learning. As to why they preferred the particular kind of teaching; the online course proponents cited mostly “comfortness” and “no-attendance obligation”; on the other hand, the face-to-face advocates mostly cited “effectiveness of learning from a live instructor” and “possibility of asking questions when something is not clear” and “lacking of technical equipment “or “internet access”.

This interpretive research set out to investigate the characteristics of an exemplary college science instructor who endeavors to improve teaching and learning in a physical science course for prospective teachers. The course was innovative in the sense that it was designed to meet the specific needs of prospective elementary teachers who needed to have models of how to teach science in a way that employed materials and small group activities. The central purpose for this study is to understand the metaphors that Mark (a pseudonym), the chemistry instructor in the course, used as referents to conceptualize his roles and frame actions and interactions in the classroom. Within the theoretical frame of constructivism, human cognitive interests, and co-participation theories, an ethnographic research design, described by Erickson (1986), Guba and Lincoln (1989), and Gallagher (1991), was employed in the study. The main sources of data for this study were field notes, transcript analysis of interviews with the instructor and students, and analyses of videotaped excerpts. Additional data sources, such as student journals and the results of students' responses to the University/Community College Student Questionnaire which was developed by a group science education researchers at Florida State University, were employed to maximize that the assertions I constructed were consistent with the variety of data. Data analyses and interpretation in the study focused on identifying the aspects which the instructor and the researcher might find useful in reflecting to understand what was happening and why that was happening in the classroom. The analysis reveals how the instructor used constructivism as a referent for his teaching and the learning of his students.

The present study examined young children's understanding of respiration and oxygen as a source of vital energy underlying physical activity. Specifically, the purpose of the study was to explore whether a coherent biological theory, characterized by an understanding that bodily parts (heart and lungs) and processes (oxygen in respiration) as part of a biological system, can be taught as a foundational concept to reason about physical activity. The effects of a biology-based intervention curriculum designed to teach preschool children about bodily functions as a part of the respiratory system, the role of oxygen as a vital substance and how physical activity acts an energy source were examined. Participants were recruited from three private preschool classrooms (two treatment; 1 control) in Southern California and included a total of 48 four-year-old children (30 treatment; 18 control). Findings from this study suggested that young children could be taught relevant biological concepts about the role of oxygen in respiratory processes. Children who received biology-based intervention curriculum made significant gains in their understanding of the biology of respiration, identification of physical and sedentary activities. In addition these children demonstrated that coherence of conceptual knowledge was correlated with improved accuracy at activity identification and reasoning about the inner workings of the body contributing to endurance. Findings from this study provided evidence to support the benefits of providing age appropriate but complex coherent biological instruction to children in early childhood settings.
The purpose of this study was to examine the constructivist-based " case study teaching methodology" in High School Biology classes, specifically investigating the effect this methodology had on Academic Achievement, Science Attitudes, Problem Solving Skills, and Teamwork Skills. The effect of Teacher Beliefs toward constructivist learning environments was also explored and investigated, using a quantitative measure (the Constructivist Learning Environment Survey, or CLES). A quasi-experimental design used eleven classes, five teachers, and two hundred fifty two high school biology students over two separate, consecutive quarters of a school year. Two researcher-made instruments measured Academic Achievement after each study quarter. T-Tests were used to compare the Experimental Group (Case Study Teaching Methodology) to the Control Group (Traditional Teaching) during each study quarter. Otis-Lennon School Ability Test (OLSAT) scores were used as a covariate for ANCOVA tests. Case Study Teaching Methodology had a statistically significant improvement on Academic Achievement during the first study quarter, but not the second quarter. Case Study Teaching Methodology had a statistically significant improvement on four of seven Science Attitudes, Problem Solving Skills, and Teamwork Skills during the second quarter of the study. This study is significant in that it addresses a knowledge gap regarding the effects of the constructivist-based case study teaching methodology on secondary science education. The theoretical implications of this study are meaningful: empirical evidence is added to the growing knowledge base regarding the benefits of constructivist theory. The practical implications are equally meaningful: case study teaching methodology is supported as an effective application of constructivist theory in the secondary science classroom.
Full Text Available The purpose of this study was to investigate the application of the model of the “flipped classroom” as a complementary method to school distance education in junior high school Biology. The “flipped classroom” model attempts a different way of organizing the educational process according to which the traditional methods of learning at school and studying at home are interchanged, the learners’ active involvement is supported, their autonomy is reinforced, ICT is utilized and learning occurs partially by distance (blended learning. We performed an action research implementing flipped classroom in Biology teaching in a class of 17 students attending the1st year of junior high school. The educational platform used was the Learning Activity Management System (LAMS. The findings were evaluated qualitative rather than quantitative, and can provide evidence about the prevailing situation. During the action research, it became evident that time management in the classroom was improved. Furthermore, it was observed that students’ involvement in the educational process was also improved. Students had already familiarized themselves with the cognitive aspect of the lesson before entering the class and they considered the learning process as an individual affair which does not only depend on the teacher. The implementation of digital activities accomplished by distance led to taking action and initiative and finally to active learning. School distance education combined with the radical development of ICT can be complementary with the use of various methods, like the “flipped learning”, and give a new perspective and potential to the limited choices of conventional education in the Greek educational system which is worth further investigation.

To identify changes in the teaching of nontechnical skills, knowledge, aptitudes, and attitudes (SKAs) at US colleges and schools of veterinary medicine between 1999 and 2009. Design-Cross-sectional survey. All 28 US colleges and schools of veterinary medicine. Procedures-An electronic questionnaire was sent to the entire study population. Results were compared with published results of a similar survey performed in 1999 of colleges and schools of veterinary medicine in the United States and Canada. A 100% response rate was achieved. All respondents were found to offer at least 1 course related to SKAs in 2009, compared with 94% (29/31) of respondents in 1999. A total of 110 such courses were documented, compared with 47 in 1999. In 2009, 26 of the 28 (93%) colleges and schools had at least 1 course related to SKAs that was required, compared with 17 of the 31 (55%) respondents to the 1999 survey. Courses were most commonly incorporated in years 1 and 3 of the curriculum and were most often valued at 1 or 2 credit hours. Forty-one of 67 (61%) courses had been developed since 1999. The most common topics were communication and financial management. Results demonstrated an increased commitment to teaching the SKAs on the part of the US colleges and schools of veterinary medicine. However, the question remains as to how effective these initiatives will be in enhancing the economic success of graduates and the veterinary medical profession in general.

Full Text Available This paper presents a study carried out with Biology teachers under training, and aimed at investigating how concept maps enabled meaningful learning. The work was motivated by the fact that future teachers presented difficulties learning various concepts. In this light, maps can be a valuable instrument for the diagnosis and assessment of learning, enabling better concept learning. Thus, during our pedagogical intervention, we have strived to identify the conceptual evolution of students, through the construction of concept maps before, during and after the study of a proposed theme. The qualitative analysis of the produced maps focused on the processes of teaching, learning and assessment. At this point, the goal was to investigate whether or not students were able to relate the concepts under study, according to the principles of progressive differentiation and integrative reconcilitation. This was done while searching for evidences of meaningful learning.The pedagogical intervention lasted for 45 hours (8 meetings, during which a Zoology topic, concept Elephants was studied at a State university of Brazil. The qualitative analysis of the maps created by the learners has shown, in 58% of the cases, that there was an evolution of the learnersʼ knowledge of the theme. Obtained results suggest that maps have an efficient functional action and help improve the professional profile under formation.

E-learning is the use of Information and Communication Technology (ICT) to provide online education and learning. E- Learning has now been integrated into the traditional teaching as the concept of 'blended learning' that combines digital learning with the existing traditional teaching methods to address the various challenges in the field of medical education. Structured e-learning activities were started in Melaka Manipal Medical College in 2009 via e-learning platform (MOODLE-Modular Object-Oriented Dynamic Learning Environment). The objective of the present study is to investigate the faculty opinions toward the existing e-learning activities, and to analyse the extent of adopting and integration of e-learning into their traditional teaching methods. A cross sectional study was conducted among faculties of Medicine and Dentistry using pre-tested questionnaires. The data was analyzed by using the statistical package for social science, SPSS, version 16.0. The result of our survey indicates that majority of our faculty (65.4%) held positive opinion towards e-learning. Among the few, who demonstrated reservations, it is attributed to their average level of skills and aptitude in the use of computers that was statistically significant (plearning that enables smooth transition of the faculty from their traditional teaching methods into blended approach. Our results are anticipated to strengthen the existing e-learning activities of our college and other universities and convincingly adopt e-learning as a viable teaching and learning strategy.

There is an increasing need for students in the biological sciences to build a strong foundation in quantitative approaches to data analyses. Although most science, engineering, and math field majors are required to take at least one statistics course, statistical analysis is poorly integrated into undergraduate biology course work, particularly at the lower-division level. Elements of statistics were incorporated into an introductory biology course, including a review of statistics concepts and opportunity for students to perform statistical analysis in a biological context. Learning gains were measured with an 11-item statistics learning survey instrument developed for the course. Students showed a statistically significant 25% (p < 0.005) increase in statistics knowledge after completing introductory biology. Students improved their scores on the survey after completing introductory biology, even if they had previously completed an introductory statistics course (9%, improvement p < 0.005). Students retested 1 yr after completing introductory biology showed no loss of their statistics knowledge as measured by this instrument, suggesting that the use of statistics in biology course work may aid long-term retention of statistics knowledge. No statistically significant differences in learning were detected between male and female students in the study.

University faculty often express frustration with the accuracy of students' understanding of science in general and of evolution in particular. A rich research literature suggests that inquiry-based pedagogies are more effective in producing meaningful learning than are traditional, didactic approaches. A pragmatic investigation into the efficacy of inquiry-based curricular reforms compared to traditional laboratory activities was undertaken in the introductory biology course for majors at a large state university in the southeastern United States. The topics of the course focused on biodiversity, evolution, and plant and animal anatomy and physiology. Students' learning in the inquiry versus traditional units was compared using both a test of pre-post content knowledge as well as open-ended written responses in which students described events in which there was meaningful learning and conceptual changes. The pre-post tests were replicated over five semesters of the same course (n = 1493 students). Students' misconceptions as well as examples of meaningful learning were gathered for two semesters in the same course (n = 518 students). Results consistently revealed that descriptive, concrete topics such as anatomy can be taught effectively using traditional didactic methods; average effect sizes (a measure of the difference between pretest scores and posttest scores) range from 1.8 to 2.1. The inquiry units also increased knowledge of content on the topics of evolution and biodiversity by a significant degree (average effect sizes range from 1.0 to 1.1), despite the fact that students spent less than half the instructional time on these units compared to the didactic units. In addition, a literature review indicated that highly abstract or mathematical concepts such as evolution or geologic time require greater formal reasoning ability and that students often show lesser gains in these areas compared to more concrete topics. It was therefore especially notable that

Background: The ubiquity, availability and exponential growth of digital information and communication technology (ICT) creates unique opportunities for learning and teaching in the senior secondary school biology curriculum. Digital technologies make it possible for emerging disciplinary knowledge and understanding of biological processes previously too small, large, slow or fast to be taught. Indeed, much of bioscience can now be effectively taught via digital technology, since its representational and symbolic forms are in digital formats. Purpose: This paper is part of a larger Australian study dealing with the technologies and modalities of learning biology in secondary schools. Sample: The classroom practices of three experienced biology teachers, working in a range of NSW secondary schools, are compared and contrasted to illustrate how the challenges of limited technologies are confronted to seamlessly integrate what is available into a number of molecular genetics lessons to enhance student learning. Design and method: The data are qualitative and the analysis is based on video classroom observations and semi-structured teacher interviews. Results: Findings indicate that if professional development opportunities are provided where the pedagogy of learning and teaching of both the relevant biology and its digital representations are available, then teachers see the immediate pedagogic benefit to student learning. In particular, teachers use ICT for challenging genetic concepts despite limited computer hardware and software availability. Conclusion: Experienced teachers incorporate ICT, however limited, in order to improve the quality of student learning.

The earthworm is ideal for studying action potential conduction velocity in a classroom setting, as its simple linear anatomy allows easy axon length measurements and the worm's sparse coding allows single action potentials to be easily identified. The earthworm has two giant fiber systems (lateral and medial) with different conduction velocities that can be easily measured by manipulating electrode placement and the tactile stimulus. Here, we present a portable and robust experimental setup that allows students to perform conduction velocity measurements within a 30-min to 1-h laboratory session. Our improvement over this well-known preparation is the combination of behaviorally relevant tactile stimuli (avoiding electrical stimulation) with the invention of minimal, low-cost, and portable equipment. We tested these experiments during workshops in both a high school and college classroom environment and found positive learning outcomes when we compared pre- and posttests taken by the students.

The purpose of this study was to determine the effects that a pre-laboratory guide, conceptualized as a "scientific story grammar," has on college chemistry students' learning when they read an introductory chemistry laboratory manual and perform the experiments in the chemistry laboratory. The participants (N = 56) were students enrolled in four existing general chemistry laboratory sections taught by two instructors at a women's liberal arts college. The pre-laboratory guide consisted of eight questions about the experiment, including the purpose, chemical species, variables, chemical method, procedure, and hypothesis. The effects of the intervention were compared with those of the traditional pre-laboratory assignment for the eight chemistry experiments. Measures included quizzes, tests, chemistry achievement test, science process skills test, laboratory reports, laboratory average, and semester grade. The covariates were mathematical aptitude and prior knowledge of chemistry and science processes, on which the groups differed significantly. The study captured students' perceptions of their experience in general chemistry through a survey and interviews with eight students. The only significant differences in the treatment group's performance were in some subscores on lecture items and laboratory items on the quizzes. An apparent induction period was noted, in that significant measures occurred in mid-semester. Voluntary study with the pre-laboratory guide by control students precluded significant differences on measures given later in the semester. The groups' responses to the survey were similar. Significant instructor effects on three survey items were corroborated by the interviews. The researcher's students were more positive about their pre-laboratory tasks, enjoyed the laboratory sessions more, and were more confident about doing chemistry experiments than the laboratory instructor's groups due to differences in scaffolding by the instructors.

Professionalism and ethics have gained widespread recognition as competencies to be fulfilled, taught, and assessed within medical education. The role of the anatomy course in developed nations has evolved over time and now encompasses multiple domains, including knowledge, skills, and the inculcation of professionalism and ethics. The Medical Council of India recently recommended the integration of professionalism teaching in undergraduate medical curricula. The authors investigated whether the initial orientation lectures and instructions given by faculty at the outset of undergraduate medical anatomy courses throughout India served a "hidden curriculum" regarding professionalism practices, and whether these orientation messages could serve as an early exposure to medical professionalism and ethics for medical students. An online survey was carried out among 102 anatomy faculty members across India requesting details about specific professionalism protocols and instructions regarding behavior in the dissection hall that are routinely given to preclinical students, as well as the importance that they placed on professional behavior. It was found that most faculty members regularly instruct students regarding expected behavior during the anatomy course, including dissection practices. These instructions stress attributes of professionalism like humanism, accountability, and honesty. However, there needs to be a more concentrated effort by educators to prohibit such unprofessional practices like dissection hall photography, and better information is required regarding biomedical waste disposal. Despite the absence of clear guidelines for professionalism teaching in medical education in India, the existing framework of anatomy education provides an opportunity to introduce the concept of professionalism to the first-year medical student. This opportunity may provide an early foundation for designing a professionalism-integrated curriculum. Anat Sci Educ 10: 433

Full Text Available Here we present a mechanism to infuse ecology into the classroom using a broadly adaptable system. We developed a novel moss-based project that introduces research-based experiences for middle school students, and can be modified for integration into K-16 classrooms. The project is ecologically relevant, facilliating opportunities for students to experience intimate interactions with ecosystem subtleties by asking their own questions. We describe and suggest how students can develop, build, test, and assess microcosm experiments of their own design, learning the process of science by “doing science.” Details on project execution, representative examples of distinctive research-question-based projects are presented. We aim for biology educators to adopt, replicate, modify, and formally assess this relatively simple, low-cost moss-based project across classroom levels. The project provides a chance for students to experience the complexity of a dynamic ecosystem via a research project of their own design as they practice basic tenets of scientific discovery. Editor's Note:The ASM advocates that students must successfully demonstrate the ability to explain and practice safe laboratory techniques. For more information, read the laboratory safety section of the ASM Curriculum Recommendations: Introductory Course in Microbiology and the Guidelines for Biosafety in Teaching Laboratories, available at www.asm.org. The Editors of JMBE recommend that adopters of the protocols included in this article follow a minimum of Biosafety Level 1 practices. Adopters who wish to culture microbes from the moss as an extension of this protocol should follow Biosafety Level 2 practices.

The purpose of this study was to investigate the attitudes toward science and science teaching of Saudi pre-service elementary science teachers at male and female teachers' colleges by using an Arabic translation of the Science Teaching Attitudes Scale (STAS-II) constructed by Moore and Foy (1997). It also used an Inquiry-based Science Instruction Questionnaire (ISIQ) constructed by the researcher to explore the relationship between self-reported inquiry-based science instructional experiences that the pre-service elementary science teachers had during their science preparation, their intention to practice inquiry-based science instruction in their future careers, and their attitudes toward science and science teaching. The sample size of the study was 300 Saudi male and female pre-service elementary science teachers at two teachers' colleges in Medina, Saudi Arabia. Two-way multivariate analysis of variance (MANOVA) was used to test the first three hypotheses because the study has two independent (gender and grade level) and two dependent (attitudes toward science and attitudes toward science teaching) variables. The Pearson Correlation Coefficient Procedure was used to test the other hypotheses. In addition, all tests were conducted at alpha = 0.05. One of the findings of the study revealed that both Saudi male and female preservice elementary science teachers had positive attitudes toward science and toward science teaching, but females had more favorable attitudes toward science than males. The result of the MANOVA showed that there was a significant mean difference between males and females in regard to pre-service elementary science teachers' attitudes toward science (p = .002), but no difference between grade levels, or in the interaction between grade levels and gender. The result of the Pearson Correlation Coefficient Procedure showed that there were significant (moderate positive) correlations between pre-service elementary science teachers' attitudes

This paper deals with the methodological aspects of teaching histology at the medical university and medical college. The authors raise the issue of the necessity of teaching of the topic "Introduction to Special Histology" and the inclusion of the appropriate chapter into the textbooks. This is important for the students, as the formation of the general concepts of organ structure and function, components, and classification will aid in the further study of specific organs during the course of Special Histology. The authors describe their own experience in teaching of the section, dedicated to the general regularities of organ structure, present some definitions and classifications that are used by them for a number of years.

Cell-free protein synthesis (CFPS) has emerged as a practical method for producing a broad variety of proteins. In addition, the direct accessibility to the reaction environment makes CFPS particularly suitable as a learning vehicle for fundamental biological concepts. Here, we describe its implementation as a teaching tool for a high school laboratory course. Ninety students in a biotechnology class used CFPS to study the effects of the concentrations of amino acids, cell extract, DNA, and the energy source on accumulation of active super-folder green fluorescent protein. Students estimated product concentrations simply by comparing solution colors to a printed green color gradient. This simple and inexpensive method allows for immediate measurements, and 26 of the 30 groups observed measurable product concentrations within 60 min. These student-generated data were then discussed to illustrate concepts of data analysis such as outliers and standard deviation. We also combined the laboratory experience with a visit to a university campus that included a laboratory tour and a college-style lecture. Our overall objective was to excite the students about the scientific enterprise and to instill a sense of personal relevance and attainability so that these students could realistically consider technical careers.

Full Text Available The influence of the evolutionary theory is widespread in modern worldview. Due to its great explanatory power and pervasiveness, the theory of evolution should be used as the organizing theme in biology teaching. For this purpose, the essential concepts of phylogenetic systematics are useful as a didactic instrument. The phylogenetic method was the first objective set of rules to implement in systematics the evolutionary view that the organisms are all connected at some hierarchical level due to common ancestry, as suggested by Darwin and Wallace. Phylogenetic systematics was firstly proposed by the German Entomologist Willi Hennig in 1950 and had considerably importance in the decrease of the role of essentialism and subjectivity in classificatory studies, becoming one of the paradigms in biological systematics. Based on cladograms, a general phylogenetic reference system allows to the depiction and representation of large amounts of biological information in branching diagrams. Besides, the phylogenetic approach sheds light upon typical misconceptions concerning evolution and related concepts that directly affect students' comprehension about the evolutionary process and the hierarchical structure of the living world. The phylogenetic method is also a form of introducing students to some of the philosophical and scientific idiosyncrasies, providing them the ability to understand concepts such as hypothesis, theory, paradigm and falsifiability. The students are incited to use arguments during the process of accepting or denying scientific hypotheses, which overcomes the mere assimilation of knowledge previously elaborated.A influência da teoria evolutiva é disseminada na visão de mundo moderna. Devido a seu grande poder explanatório e penetração, a teoria da evolução deve ser usada como o tema organizador do ensino de biologia.

Lack of physical activity, consumption of junk food, habit of not taking breakfast and consuming food in canteen, home and mess are found to have significant association with obesity and overweight. CONCLUSION The problem of obesity is on rise and there is a definite need to inculcate good habits of healthy eating and regular physical exercise.
Teachers are the most important factor in student learning (National Research Council, 1996); yet little is known about the specialized knowledge held by experienced teachers. The purpose of this study was twofold: first, to make explicit the pedagogical content knowledge (PCK) for teaching diffusion and osmosis held by experienced biology teachers and, second, to reveal how topic-specific PCK informs teacher practice. The Magnusson et al. (1999) PCK model served as the theoretical framework for the study. The overarching research question was: When teaching lessons on osmosis and diffusion, how do experienced biology teachers draw upon their topic-specific pedagogical content knowledge? Data sources included observations of two consecutive lessons, three semi-structured interviews, lesson plans, and student handouts. Data analysis indicated five of the six teachers held a constructivist orientation to science teaching and engaged students in explorations of diffusion and osmosis prior to introducing the concepts to students. Explanations for diffusion and osmosis were based upon students' observations and experiences during explorations. All six teachers used representations at the molecular, cellular, and plant organ levels to serve as foci for explorations of diffusion and osmosis. Three potential learning difficulties identified by the teachers included: (a) understanding vocabulary terms, (b) predicting the direction of osmosis, and (c) identifying random molecular motion as the driving force for diffusion and osmosis. Participants used student predictions as formative assessments to reveal misconceptions before instruction and evaluate conceptual understanding during instruction. This study includes implications for teacher preparation, research, and policy.

Departments of animal sciences must be relevant to a society in which a small number of people can raise almost all the food animal products needed. The declining number of people involved in animal agriculture has decreased enrollment of students interested in food animals in many departments of animal science. However, several departments welcomed students from a diverse background and began research on animals other than food animals. In many states, the undergraduate enrollment is made up primarily of students interested only in companion animals. A benefit of this is that we have recruited new students into animal agriculture and they have gone on to excellent careers. We have a new challenge now: how to maintain and expand the efforts in teaching, research, and outreach of companion animal science. Departments wishing to expand in teaching have examples of successful courses and curricula from other departments. Some departments have expanded their teaching efforts across their own university to teach about pets to a wider audience than their own majors; other departments can follow. In research, a small number of faculty have been able to establish extramurally funded projects on pets, including horses. But it will be difficult for more than a handful of departments to have a serious research effort in dogs, cats, birds, fish, or exotic animals. Departments will have to make a concerted effort to invest in such endeavors; joint ventures with other universities and colleges of veterinary medicine (or medicine) will probably be required. Funding sources for "traditional" efforts in nutrition, reproduction, and physiology are small and inconsistent; however, with the progress of the equine, canine, and feline genome projects, there should be opportunities from federal funding sources aimed at using animal models for human health. In addition, efforts in animal behavior and welfare can be expanded, perhaps with some funding from private foundations or animal

Full Text Available The main goal of this work was to identify the didactic and teaching practice aspects of the superior education teacher under the perception of the students in the Course of Biologic Sciences. It was applied a questionnaire that focused the aspects of education strategies, behaviors and attitudes of the professor in classroom. Were analyzed 69 questionnaires, and the answers had indicated that the majority of the classes was oral-expositive, however the students prefer lessons with discussion and debates. The students gave emphasis to the content domain, considering it the most important component for the good teacher, also the use of different teaching strategies and the teacher-student relationship. It was observed that the notes of the students corroborate to the available bibliographical references on the teaching-learning process and didactics, especially, when they disaccorded that the superior didactics is thought as something to “knowing to teach”. It was observed that the pedagogical practices could be changed to improve the teaching-learning and the motivation of the students. This study had great importance in the survey of the main questions that occur daily in the classroom and the characteristics that the good professor would have to acquire.
The underrepresentation of women enrolled in the physical sciences continues to challenge academic leaders despite over 40 years of programming to promote gender equity within these curricula. This study employed a quantitative, causal comparative method to explore if and to what extent career concerns differed among female and male undergraduate physical and biological science students. The theory of planned behavior and life-span, life-space theory served as the theoretical framework for the study. Quantitative survey data were collected from 43 students at four institutions across the United States. The findings indicated that undergraduate women in physical science programs of study had a significantly different level of concern about the Innovating sub-category of the third stage of career development, Maintenance, as compared to undergraduate women in biological science curricula [F(1,33) = 6.244, p = 0.018]. Additionally, there was a statistically significant difference between female undergraduate physical science students and undergraduate male science students in the sub-categories of Implementation [F(1,19) = 7.228, p = 0.015], Advancing [F(1,19) = 11.877, p = 0.003], and Innovating [F(1,19) = 11.782, p = 0.003] within the first three stages of career development (Exploration, Establishment, and Maintenance). The comparative differences among the study groups offers new information about undergraduate career concerns that may contribute to the underrepresentation of women enrolled in the physical sciences. Suggestions for future research and programs within higher education targeted at reducing the career concerns of current and prospective female students in physical science curricula are discussed.

Teaching high school students about the digestive system can be a challenge for a teacher when s/he wants to overcome rote learning of facts without a deeper understanding of the physiological processes inside the alimentary tract. A series of model experiments illustrating the journey of a sandwich was introduced into teaching high school biology. Using a computer equipped with a commercially available data-acquisition system and a couple of sensors, it was possible to illustrate the basic underlying physical and chemical principles of digestion to the students. Students were able to investigate, through hands-on activities, the chewing force of the jaws, importance of the mechanical breakdown of food, enzymatic activity of pepsin and amylase, antibacterial activity of hydrochloric acid, and importance of the villi for absorption. Students found the experiments interesting and helpful for understanding the digestive process. Furthermore, the results from testing indicated that the students had a deeper understanding of the physiological processes.

Dissection has always played a crucial role in biology and anatomy courses at all levels of education. However, in recent years, ethical concerns, as well as improved technology, have brought to the forefront the issue of whether virtual dissection is as effective or whether it is more effective than traditional dissection. Most prior research indicated the two methods produced equal results. However, none of those studies examined retention of information past the initial test of knowledge. Two groups of college students currently enrolled in an introductory level college biology course were given one hour to complete a frog dissection. One group performed a traditional frog dissection, making cuts in an actual preserved frog specimen with scalpels and scissors. The other group performed a virtual frog dissection, using "The Digital Frog 2" software. Immediately after the dissections were completed, each group was given an examination consisting of questions on actual specimens, pictures generated from the computer software, and illustrations that neither group had seen. Two weeks later, unannounced, the groups took the same exam in order to test retention. The traditional dissection group scored significantly higher on two of the three sections, as well as the total score on the initial exam. However, with the exception of specimen questions (on which the traditional group retained significantly more information), there was no significant difference in the retention from exam 1 to exam 2 between the two groups. These results, along with the majority of prior studies, show that the two methods produce, for the most part, the same end results. Therefore, the decision of which method to employ should be based on the goals and preferences of the instructor(s) and the department. If that department's goals include: Being at the forefront of new technology, increasing time management, increasing student: teacher ratio for economic reasons, and/or ethical issues, then

Full Text Available The national College English Curriculum Requirements in China focus on college students’ overall English ability, students’ self-learning ability and teachers’ objective assessment towards students as well. This paper thus designed a syllabus for college Integrated English class based on syllabus design standard by Nunan, task-based language teaching theory by Ellis and the classroom-based assessment theory by Gottlieb and Brown and Abeywickrama. Task-based teaching and classroom-based assessment both emphasize the importance of student-centered and student-involved tasks and the overall assessment of students’ performance. This syllabus thus combined these theories, designed tasks such as in-class quick shares, textbook lecturing, social interviews and reports, written reflections of each textbook article etc. and tries to assess students’ performance through both formative and summative ways such as peer and self assessment through the evaluating rubrics of these tasks, portfolios, and final examinations. The implementation will finally test the effectiveness and efficiency of this syllabus.
The Vision and Change reports (American Association for the Advancement of Science, 2011, 2013) have identified a need for change in undergraduate biology education, emphasizing student learning of content knowledge and competencies. Missing from this report and larger efforts to improve undergraduate education (Brainard, 2007; Henderson et al., 2011; Sunal et al., 2001) are guidelines for how to support instructors' professional learning to change teaching practices. I am exploring one possible support structure by studying a group of seven biology instructors that are engaged in a collaborative process over two semesters. This process is modeled after Lesson Study (Lewis et al., 2006), a form of cyclical inquiry-based professional learning activities. The purpose of this qualitative case study is to examine the micro-processes of this collaboration and how these micro-processes afford and limit the ability to change one's teaching practices. Wenger's (1998) concept of "community of practice" provides a theoretical framework for data analysis. I view an instructor's professional learning as social and situated, involving negotiation of new meanings, boundaries, and participation as part of an on-going collaboration. Data analysis shows that negotiation of meaning, characterized by friction and dissonance, is a normal part of the micro-processes of collaborative group work. There are three friction points that are intertwined and influence each other: 1) rhythmic ebb and flow of negotiation about a common professional goal for the instructors and a common learning goal for undergraduates in biology, 2) pressure of time to produce an outcome, and 3) grappling with collective agency, authority and capacity. I argue that these friction points are necessary and important for understanding the micro-processes of negotiation in a collaborative process. Furthermore, this study contributes to literature examining how the use of collaborative processes that are often

Incorporation of mathematics into biology curricula is critical to underscore for undergraduate students the relevance of mathematics to most fields of biology and the usefulness of developing quantitative process skills demanded in modern biology. At our institution, we have made significant changes to better integrate mathematics into the undergraduate biology curriculum. The curricular revision included changes in the suggested course sequence, addition of statistics and precalculus as prerequisites to core science courses, and incorporating interdisciplinary (math-biology) learning activities in genetics and zoology courses. In this article, we describe the activities developed for these two courses and the assessment tools used to measure the learning that took place with respect to biology and statistics. We distinguished the effectiveness of these learning opportunities in helping students improve their understanding of the math and statistical concepts addressed and, more importantly, their ability to apply them to solve a biological problem. We also identified areas that need emphasis in both biology and mathematics courses. In light of our observations, we recommend best practices that biology and mathematics academic departments can implement to train undergraduates for the demands of modern biology.

Full Text Available BACKGROUND Traditional lecture is the most common type of teaching learning method used in professional colleges of India. Interactive lecture seems to be an important and feasible teaching learning method to increase the effect of learning in medical education. MATERIALS & METHODS The study was performed from July 2015 to October 2015 among first year medical students in Government Medical College, Idukki. All fifty first year MBBS students of 2014 batch were divided into group A and group B by simple random method. Two topics of translation were taken to both groups by two different lecture methods. The first topic was taught by interactive lecture to group A and traditional lecture to group B on the first day. Pre-test and post-test were done to assess gain in knowledge by two lecture methods. Second topic was taken to both groups on the second day by exchanging lecture methods. Their increase in knowledge was assessed by pre-test and post-test. On the second day, their feedback regarding perceptions and preferences were taken. STATISTICAL ANALYSIS Mean scores of pre and post-test were analysed by paired t test. Level of knowledge gained among two lecture methods was compared by independent t test and qualitative data on feedback was analysed using Chi square test. RESULTS The level of knowledge gained by interactive lectures was significantly higher than traditional lectures. Students agreed that interactive lectures motivated them for self-learning and increased their confidence regarding study materials. It also helped them in the recollection of lecture content and clearing doubt than traditional lectures. CONCLUSIONS Interactive lectures were accepted and considered to be more useful than traditional lectures for teaching biochemistry at Government Medical College, Idukki.

The objective of this study was to demonstrate the sequential process (i.e., social factors→mediators→motivation→consequences) underlying the Hierarchical Model of Intrinsic and Extrinsic Motivation at the contextual level in instruction using three teaching tools, modified balls, a high net, and colored balls and cones in a college-level tennis class in South Korea. 126 students enrolled in a 15-week tennis class participated in the study. The results indicate that the three teaching tools positively affected students' perceived competence, with perceived competence's beta on intrinsic motivation equal to 0.45. Intrinsic motivation was found to reduce negative affect further by -0.33, thereby demonstrating the sequential process of the Hierarchical Model of Intrinsic and Extrinsic Motivation.
