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. 相似文献

University Modeling Instruction (UMI) is an approach to curriculum and pedagogy that focuses instruction on engaging students in building, validating, and deploying scientific models. Modeling Instruction has been successfully implemented in both high school and university physics courses. Studies within the physics education research (PER) community have identified UMI''s positive impacts on learning gains, equity, attitudinal shifts, and self-efficacy. While the success of this pedagogical approach has been recognized within the physics community, the use of models and modeling practices is still being developed for biology. Drawing from the existing research on UMI in physics, we describe the theoretical foundations of UMI and how UMI can be adapted to include an emphasis on models and modeling for undergraduate introductory biology courses. In particular, we discuss our ongoing work to develop a framework for the first semester of a two-semester introductory biology course sequence by identifying the essential basic models for an introductory biology course sequence. 相似文献

Over the past decade, repeated calls have been made to incorporate more active teaching and learning in undergraduate biology courses. The emphasis on inquiry-based teaching is especially important in laboratory courses, as these are the courses in which students are applying the process of science. To determine the current state of research on inquiry-based teaching in undergraduate biology laboratory courses, we reviewed the recent published literature on inquiry-based exercises. The majority of studies in our data set were in the subdisciplines of biochemistry, cell biology, developmental biology, genetics, and molecular biology. In addition, most exercises were guided inquiry, rather than open ended or research based. Almost 75% of the studies included assessment data, with two-thirds of these studies including multiple types of assessment data. However, few exercises were assessed in multiple courses or at multiple institutions. Furthermore, assessments were rarely based on published instruments. Although the results of the studies in our data set show a positive effect of inquiry-based teaching in biology laboratory courses on student learning gains, research that uses the same instrument across a range of courses and institutions is needed to determine whether these results can be generalized. 相似文献

This paper describes a newly adapted instrument for measuring novice-to-expert-like perceptions about biology: the Colorado Learning Attitudes about Science Survey for Biology (CLASS-Bio). Consisting of 31 Likert-scale statements, CLASS-Bio probes a range of perceptions that vary between experts and novices, including enjoyment of the discipline, propensity to make connections to the real world, recognition of conceptual connections underlying knowledge, and problem-solving strategies. CLASS-Bio has been tested for response validity with both undergraduate students and experts (biology PhDs), allowing student responses to be directly compared with a consensus expert response. Use of CLASS-Bio to date suggests that introductory biology courses have the same challenges as introductory physics and chemistry courses: namely, students shift toward more novice-like perceptions following instruction. However, students in upper-division biology courses do not show the same novice-like shifts. CLASS-Bio can also be paired with other assessments to: 1) examine how student perceptions impact learning and conceptual understanding of biology, and 2) assess and evaluate how pedagogical techniques help students develop both expertise in problem solving and an expert-like appreciation of the nature of biology. 相似文献

Literacy instruction is a powerful determinant of children’s academic and school outcomes. Teachers’ training for literacy instruction is therefore critical for children’s reading learning. The present study examined the contents of 130 courses related to literacy instruction from a representative national sample of primary teachers’ undergraduate programs (N = 81), to address the following issues: which courses, related to literacy instruction, are included in the curriculum of undergraduate training programs? Which is the weight of the courses in undergraduate programs? What are the contents of the courses? The results show that most critical features of literacy instruction are included in the course contents of most programs (e.g. phonics, theory of literature). Still, some other critical features are underrepresented (reading/writing comprehension skills) or apparently missing (assessment and intervention in reading/writing problems). Moreover, the time allocated to literacy instruction seems to be scarce. Still, wide differences across university programs and courses were found. 相似文献

This study describes the effects on student motivation and cognitive learning strategies of an approach involving an undergraduate learner-centered community of learners approach to instruction. Six learning communities were created using the following objectives: integrated courses, active and collaborative learning, and opportunities for learning through information technology and library resources. Instructors attended ten workshops designed to assist them in developing the learning communities according to the objectives of the program. Results indicate significant changes in motivation and cognitive strategy use by the end of participation in the learning community. Within the motivation subscales, students in the learning communities reported significantly higher levels of intrinsic and extrinsic motivation, more internal control of their learning, and self-efficacy, along with significantly lower levels of test anxiety and task value. Within the learning strategies subscales, students reported increases in their use of rehearsal strategies, organization strategies, critical thinking, time management, and the use of peer learning and help-seeking behaviors. 相似文献

Active learning and research-oriented activities have been increasingly used in smaller, specialized science courses. Application of this type of scientific teaching to large enrollment introductory courses has been, however, a major challenge. The general microbiology lecture/laboratory course described has been designed to incorporate published active-learning methods. Three major case studies are used as platforms for active learning. Themes from case studies are integrated into lectures and laboratory experiments, and in class and online discussions and assignments. Students are stimulated to apply facts to problem-solving and to learn research skills such as data analysis, writing, and working in teams. This course is feasible only because of its organizational framework that makes use of teaching teams (made up of faculty, graduate assistants, and undergraduate assistants) and Web-based technology. Technology is a mode of communication, but also a system of course management. The relevance of this model to other biology courses led to assessment and evaluation, including an analysis of student responses to the new course, class performance, a university course evaluation, and retention of course learning. The results are indicative of an increase in student engagement in research-oriented activities and an appreciation of real-world context by students. 相似文献

This study used OpenTTD, a video game that supports in-depth experiential learning, to evaluate undergraduate students’ opinions regarding supply chain and logistics management learning. The 101 undergraduate participants were assigned to either an experimental group or a control group. From the post-test questionnaires, the analytical results suggested that students had more positive attitudes toward video game-based learning than toward traditional education. Additionally, video game-based learning yielded more positive learning experiences than did traditional instruction. In summary, video game-based learning was found to have positive effects on the instruction of undergraduate courses on supply chain and logistics management. 相似文献

Chemical kinetics is an extremely important concept for introductory chemistry courses. The literature suggests that instruction in chemical kinetics is often teacher‐dominated at both the secondary school and tertiary levels, and this is the case in Thailand – the educational context for this inquiry. The work reported here seeks to shift students from passive learning to more active, student‐centred learning and involved some 413 first year undergraduate science students in Thailand. Drawing on inquiry‐based learning, the participants were asked to design an experiment investigating the reaction of acids and bases. The research findings suggest that participants were able to explain the changes of the rate of a chemical reaction, and developed good conceptual understanding of chemical kinetics both qualitatively and quantitatively. It also showed this more active teaching approach, which is radically different from normal teaching in Thailand, was an enjoyable experience for the students. 相似文献

There is currently strong and widespread support among university administrators for blended learning at the college level, or courses that incorporate some degree of online instruction. As instructors are called on to incorporate online and face-to-face elements into their instruction, they face the critical question of how to intentionally connect the two modalities in ways that strengthen learning. This article first outlines the historical context of social-constructivism's presence in online instruction, and then presents a rationale for the use of “crossover” discussion protocols that connect online forums and face-to-face discussions. The article argues that by drawing deliberately on the benefits of both online and in-person learning environments, crossover protocols help students make more insightful connections among ideas and push their own—and each others'—thinking in unexpected ways. A set of crossover protocols is then provided, along with considerations for implementing them effectively. These practical strategies for facilitating conversations across the two modalities were developed in the author's undergraduate and graduate level courses in English and education and are adaptable across course levels and disciplines. The article concludes with a discussion of how students experience the learning benefits of crossover protocols. 相似文献

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. 相似文献

Today, more minority students are entering undergraduate programs than ever before, but they earn only 6% of all science or engineering PhDs awarded in the United States. Many studies suggest that hands-on research activities enhance students' interest in pursuing a research career. In this paper, we present a model for the implementation of laboratory research in the undergraduate teaching laboratory using a culturally relevant approach to engage students. Laboratory modules were implemented in upper-division genetics and cell biology courses using cassava as the central theme. Students were asked to bring cassava samples from their respective towns, which allowed them to compare their field-collected samples against known lineages from agricultural stations at the end of the implementation. Assessment of content and learning perceptions revealed that our novel approach allowed students to learn while engaged in characterizing Puerto Rican cassava. In two semesters, based on the percentage of students who answered correctly in the premodule assessment for content knowledge, there was an overall improvement of 66% and 55% at the end in the genetics course and 24% and 15% in the cell biology course. Our proposed pedagogical model enhances students' professional competitiveness by providing students with valuable research skills as they work on a problem to which they can relate. 相似文献

Photographs Generate Knowledge: Reflections on Experiential Learning In/Outside the Social Work Classroom 总被引：2，自引：2，他引：0
Building active learning strategies into courses can be risky, but the benefits to students often outweigh the concerns, as in the case presented here. The process began as an attempt to employ experiential learning, through the use of photovoice, to enhance the teaching of an undergraduate social work research course. In later courses it blossomed into a community-based research project that saw the students interacting directly with people who had experienced homelessness, and with community agencies. This article explains the transformative process that took place in Canada over 3 academic years. It includes an overview of the photovoice research approach, a discussion of the methodologies used, and reflections on student experiences during a process based on principles of co-learning, mutual benefit, capacity building, and long-term commitment to the goal of social change. 相似文献

Online learning has become a reality for many students in higher education. Unfortunately, something that has also become a reality is a sense of isolation in online courses, and Moore (1980) has warned that students' sense of distance can threaten their ability to learn. The community of inquiry framework (Garrison, Anderson, & Archer, 2000) has provided insight into ways that online interactions can improve students' and instructors' social presence and learning. Emerging video technologies may be able to improve these interactions and thus more easily support the development of communities of inquiry. In this study we interviewed students in three distinct courses using different video-based instructional strategies. A large majority of students indicated feeling that the video-based communication made their instructors seem more real, present, and familiar, and that these relationships were similar to face-to-face instruction. Video communication impacted students' social presence in similar ways, although to a lesser degree than they believed it impacted instructor social presence. We conclude with discussion for future research and practice. 相似文献

Learner‐centered approaches to science and mathematics instruction assume that only when students are active participants will learning be deep, enduring, and enjoyable, and transfer to contexts beyond the classroom. Although their beneficial effects are well known, the extent to which learner‐centered practices are used in college classrooms may be low. Surveys of undergraduate science and math majors reveal general dissatisfaction with how courses in their majors are taught, and their number is half what it was 2 decades ago. In response, federally funded systemic reform initiatives have targeted increasing the use learner‐centered instruction in science and mathematics courses to improve undergraduate education generally and the training of preservice teachers specifically. Few data exist regarding how effective these initiatives have been or how frequently learned‐centered instruction occurs as assessed from faculty's perspective, which may not corroborate undergraduate perceptions. Accordingly, a survey was developed to assess the use of learner‐centered techniques and was administered to science and math professors of Louisiana over the Internet. The return rate was 28%. Analyses reveal that they are used infrequently, but when used, are applied to all aspects of teaching. Data also suggest that federal funding has been slightly effective in promoting its use. © 2003 Wiley Periodicals, Inc. J Res Sci Teach 40: 566–584, 2003 相似文献

Abstract Universities and colleges have a responsibility to help solve complex social problems. The article describes an interdisciplinary approach that integrates the diverse strengths of a research and teaching institution to address issues in one such complex problem: race, science, and health. The authors' model involved a “feedback loop” among three different and simultaneous activities: two undergraduate courses, one in biology and one open to all first-year student, and a weekly seminar that included the professors teaching these two courses, other faculty from across the university, and undergraduate and graduate student representatives. The topic and logistical strategies are discussed in detail and the value and challenges of such an integrated multilevel approach are explored. 相似文献

Several studies have found active learning to enhance students’ motivation and attitudes. Yet, faculty indicate that students resist active learning and censure them on evaluations after incorporating active learning into their instruction, resulting in an apparent paradox. We argue that the disparity in findings across previous studies is the result of variation in the active learning instruction that was implemented. The purpose of this study was to illuminate sources of motivation from and resistance to active learning that resulted from a novel, exemplary active-learning approach rooted in essential science practices and supported by science education literature. This approach was enacted over the course of 4 weeks in eight sections of an introductory undergraduate biology laboratory course. A plant concept inventory, administered to students as a pre-, post-, and delayed-posttest indicated significant proximal and distal learning gains. Qualitative analysis of open-response questionnaires and interviews elucidated sources of motivation and resistance that resulted from this active-learning approach. Several participants indicated this approach enhanced interest, creativity, and motivation to prepare, and resulted in a challenging learning environment that facilitated the sharing of diverse perspectives and the development of a community of learners. Sources of resistance to active learning included participants’ unfamiliarity with essential science practices, having to struggle with uncertainty in the absence of authoritative information, and the extra effort required to actively construct knowledge as compared to learning via traditional, teacher-centered instruction. Implications for implementation, including tips for reducing student resistance to active learning, are discussed.

Beverage-agarose gel electrophoresis: an inquiry-based laboratory exercise with virtual adaptation 总被引：1，自引：1，他引：0
A wide range of literature and experience has shown that teaching methods that promote active learning, such as inquiry-based approaches, are more effective than those that rely on passive learning. Gel electrophoresis, one of the most common laboratory techniques in molecular biology, has a wide range of applications in the life sciences. As such, we chose it as a platform to expose high school and undergraduate students to the active process of scientific inquiry in general, while specifically teaching electrophoresis. First, we optimized DNA electrophoresis in the laboratory by using common beverages instead of standard media (e.g., Tris-based media). Second, we adapted this laboratory process of progressive optimization to a Web-based format in which students had to achieve all the same steps of optimization by performing serial electrophoreses. And third, we evaluated the use of this entirely Web-based virtual laboratory exercise in high school and undergraduate biology courses. Students learned fundamental and practical principles of electrophoresis, while experiencing the essential inquiry-based process of optimizing a technique, and they also enjoyed it. Our findings provide a readily accessible, inexpensive, and intriguing technique for teaching electrophoresis and the progressive optimization of a laboratory technique. 相似文献
