In this editorial we link the articles published in this Special Issue with the framework from Vision and Change and summarize findings from the editorial process of assembling the Special Issue.The authors of Vision and Change (American Association for the Advancement of Science [AAAS], 2011 ) issued the following call to action to biologists, physicists, chemists, and mathematicians:
To ensure that all students graduate with a basic level of scientific literacy and meet the challenges raised in Bio 2010: Transforming Undergraduate Education for Future Research Biologists (2003), Scientific Foundations for Future Physicians: Report of the AAMC-HHMI Committee (2009), A New Biology for the 21st Century (2009), and similar reports, biologists, physicists, chemists, and mathematicians need to look thoughtfully at ways they can introduce interdisciplinary approaches into their gateway courses. (AAAS, 2011 , p 54)The articles that comprise this special issue of CBE—Life Sciences Education (LSE) take important steps toward responding to this call by describing teaching and learning at the intersection of biology and physics. Broadly defined, the work aims to encourage the development of genuine interdisciplinary understanding, or “the capacity to integrate knowledge and modes of thinking in two or more disciplines or established areas of expertise to produce a cognitive advancement … in ways that would have been impossible or unlikely through single disciplinary means” (Boix Mansilla and Duraisingh, 2007 , p. 219). Indeed, many of the most exciting recent breakthroughs in the life sciences have occurred at the intersection of these established disciplines. Physical laws help to predict, describe, and explain biological phenomena occurring at molecular to ecosystem levels, and the development of new physical tools helps to visualize these phenomena in new and informative ways. Thus, the Vision and Change report stresses the urgency for undergraduate biology and physics educators to develop, assess, and revise content materials, pedagogical strategies, and epistemological perspectives for encouraging student learning in interdisciplinary biology and physics classes.We received more than 50 abstracts in response to the call for this special issue, and we are pleased to publish 10 Articles, four Essays, and eight Features reflecting the state of educational transformation at the intersection of biology and physics. Several articles describe integration of physics into biology curriculum or biology into physics curriculum that goes beyond simple provision of examples from the respective disciplines (e.g., Batiza et al., Christensen et al., Svoboda Gouvea et al., O’Shea et al., Thompson et al., Breckler et al.). A number of articles address cross-cutting themes, such as problem solving (e.g., Hoskinson et al.) and energy (e.g., Cooper and Klymkowsky, Svoboda Gouvea et al.), the application of mathematical laws to biological phenomena (e.g., Redish and Cooke), epistemology (e.g., Watkins and Elby), and assessment as a powerful tool for driving curriculum change, in this case the integration of physics and biological thinking (e.g., Svoboda Gouvea et al., Momsen et al., Thompson et al.). Other articles reflect research crossing disciplinary boundaries to introduce research approaches (e.g., Watkins and Elby, Momsen et al.) or innovative curriculum models (e.g., Manthey and Brewe, Donovan et al., Thompson et al.) to help students develop reasoning strategies that move beyond traditional disciplinary boundaries. The Hillborn and Friedlander essay highlights potential impacts of cross-disciplinary collaboration in education on the revised Medical College Admission Test.We were pleased by the number of articles coauthored by physicists and biologists working in teams to examine and recommend new directions for the future of biology education. These teams brought a richness and depth of knowledge in both disciplines that made it possible to move instruction and research forward at the intersection of the disciplines. Together, these articles start to provide the evidence base for responding to the calls for interdisciplinary teaching and learning. Further, they provide opportunities to compare and contrast education and epistemologies in biology and physics, allowing for more informed integration of knowledge from these disciplines. 相似文献

The purpose of this study was to assess the relationship between temporal and structural components of organizational life (i.e., job tenure, employment history, and organizational history) and employee dissent. This was accomplished by comparing respondents’ reports about their tendencies to use varying strategies for dissent to their reports about present job tenure, number of full‐time employers, total years work experience, and organizational status. Structural equation models were used to examine the association between temporal measures (job tenure, number of full‐time employers, total years work experience), structural measures (organizational status) and dissent constructs. Findings indicated that articulated dissent use was associated with management status, whereas latent dissent use was associated with nonmanagement status, increases in present job tenure and decreases in number of full‐time employers and total years work experience. 相似文献

Our objective was to investigate the impact of the Science Writing Heuristic (SWH) on undergraduates’ ability to express logical conclusions and include appropriate evidence in formal writing assignments. Students in three laboratory sections were randomly allocated to the SWH treatment (n?=?51 students) with another three sections serving as a control (n?=?47 students). All sections received an identical formal writing assignment to report results of laboratory activities. Four blinded raters used a 6-point rating scheme to evaluate the quality of students’ writing performance. Raters’ independent scoring agreement was evaluated using Cronbach's α. Paper scores were compared using a t-test, then papers were combined into low-scoring (3.5 of 6 points) or high-scoring (>3.5 of 6 points) sets and SWH and control cohorts were compared using Pearson's chi-square test. Papers from the SWH cohort were significantly (P?=?0.02) more likely to receive a high score than those from the control cohort. Overall scores of SWH cohort papers tended to be higher (P?=?0.07) than those from the control cohort. Gains in student conceptual understanding elicited by the SWH approach improved student ability to express logical conclusions about their data and include appropriate evidence to support those conclusions in formal research reports. Extending the writing tasks of the SWH to formal writing assignments can improve the ability of undergraduates to argue effectively for their research findings. 相似文献

Constructivism is an important theory of learning that is used to guide the development of new teaching methods, particularly in science education. However, because it is a theory of learning and not of teaching, constructivism is often either misused or misunderstood. Here we describe the four essential features of constructivism: eliciting prior knowledge, creating cognitive dissonance, application of new knowledge with feedback, and reflection on learning. We then use the criteria we developed to evaluate five representative published articles that claim to describe and test constructivist teaching methods. Of these five articles, we demonstrate that three do not adhere to the constructivist criteria, whereas two provide strong examples of how constructivism can be employed as a teaching method. We suggest that application of the four essential criteria will be a useful tool for all professional educators who plan to implement or evaluate constructivist teaching methods. 相似文献

ABSTRACTResearch in learning progressions (LPs) has been essential towards building understanding of how students’ ideas change over time. There has been little work, however, into how ideas between separate but related constructs within a multi-faceted LP relate. The purpose of this paper is to elaborate on the idea of progression webs to model connections within and between related constructs simultaneously, and to explain and demonstrate the efficacy of path analysis towards validating a hypothesised progression web for understanding of modern genetics. Specifically, we evaluate strength of evidence for a progression web based upon multiple related constructs within a multi-faceted LP describing undergraduate biology students’ understanding of genetics. We then utilise the progression web to generalise theory around how undergraduate students understand relationships between related genetics concepts, and how they use simpler concepts to scaffold those which are more complex. 相似文献

This article reviews empirically based studies demonstrating gender‐biased perceptions resulting from use of “man”‐linked words (e.g., “mankind”) and third‐person‐singular masculine pronouns. Contrary to commonsense beliefs, neither of these linguistic conventions has been found to he associated with equal likelihood perceptions of female and male referents. Specific suggestions are made for the adoption of alternatives to masculine generics in speech and communication teaching and research reportage. Also, suggestions are made for research and development activities. 相似文献

This study investigated the personality and viewing-motivation correlates of reality television exposure. Results from a survey of 592 undergraduates showed that extroversion negatively predicted reality television exposure, whereas neuroticism was not associated with it. Both instrumental (social interaction, information, and arousal) and ritualized (relaxation, pass time, entertainment, and companionship) viewing motivations positively predicted exposure to reality television. A two-stage model by which personality traits contributed to viewing motivations, which, in turn, contributed to the selection of reality television, was tested and offered an adequate fit to the data. Implications for uses and gratifications research are discussed. 相似文献
