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.

The impact of institutional factors on student academic results: implications for ‘quality’ in universities 总被引：1，自引：0，他引：1
This paper situates the topic of student assessment and the moderation of assessment within a broader context of policy debates about the quality of teaching and learning in universities. The focus and discussion grew out of a research project that aimed to investigate factors related to academic success and failure in a Faculty of Arts. The study, initially, identified a range of student demographic and biographical factors significantly related to academic success and failure. However, there was also evidence of pronounced differences in grading practices between different components (courses, programs, schools) within the institution. The paper explores the implications of such inconsistencies for the institutional mechanisms and processes that have typically been advocated as sufficient safeguards of quality. It concludes that the tendency of governments and other stakeholders to now champion performance indicators, along with the shifting focus towards quality ‘outcomes’, are likely to increasingly throw the strengths and weaknesses of institutional assessment practices into stark relief. 相似文献

Socioscientific issues encompass social dilemmas with conceptual or technological links to science. The process of resolving these issues is best characterized by informal reasoning which describes the generation and evaluation of positions in response to complex situations. This article presents a critical review of research related to informal reasoning regarding socioscientific issues. The findings reviewed address (a) socioscientific argumentation; (b) relationships between nature of science conceptualizations and socioscientific decision making; (c) the evaluation of information pertaining to socioscientific issues, including student ideas about what counts as evidence; and (d) the influence of an individual's conceptual understanding on his or her informal reasoning. This synthesis of the current state of socioscientific issue research provides a comprehensive framework from which future research can be motivated and decisions about the design and implementation of socioscientific curricula can be made. The implications for future research and classroom applications are discussed. © 2004 Wiley Periodicals, Inc. J Res Sci Teach 41: 513–536, 2004 相似文献

Students at America’s most renowned private universities face different acceptance rates, college wealth, class sizes, and potential graduate earnings even in comparison with students at the nation’s highest-ranking public institutions. The analyses that led to these findings frequently focused on national or state-wide comparisons of public versus private universities. This paper contrasts these studies by analysing a fixed group of colleges, those regularly listed in the global top 50 of research and reputation rankings. It argues that even within this small subset of colleges, the highest-ranking public universities have more in common with their similarly positioned private counterparts than with lower ranking public institutions; a finding reflected in assessments of private colleges. Subsequently, the paper finds that student experiences are more likely defined by a college’s reputational rank than by an institution’s public or private status, endowment, or acceptance rates, however, the same was found not to be true of potential graduate earnings. 相似文献

Editor's note. In the 1970s Professor Nicholas Hobbs directed a comprehensive study on child classification while Provost at Vanderbilt University in the USA. Though neglected in recent years his 1975 edited text, 'Issues in the Classification of Children', remains a relevant and important source of thinking about categorisation. Given the current policy interest in categories of special educational need it seems appropriate to reconsider some of these ideas. The following article originally appeared as Chapter 4 from Volume One of the Hobbs text. It is reprinted here with the kind permission of the Hobbs family.

Antibiotic resistance (ABR) is a significant contemporary socio-scientific issue. To engage in informed reasoning about ABR, students need to understand natural selection. A secondary science unit was designed and implemented, combining an issues-based approach and model-based reasoning, to teach students about natural selection and ABR. This sequential explanatory mixed methods study explored students’ explanations of natural selection. Students created model-based explanations (MBEs) about ABR and verbally explained generalised natural selection during semi-structured interviews. Students’ MBEs significantly increased in natural selection content, and misconceptions about natural selection and ABR significantly decreased after the unit. However, students’ explanations of generalised natural selection differed from ABR explanations. Students struggled to include mutation as the cause of initial variation when explaining generalised natural selection, whereas students included mutation when explaining ABR but often did so after selection pressure. Qualitative analysis indicated students correctly explained ABR or correctly explained generalised natural selection, but none correctly explained both. Students who did understand ABR struggled to apply their understanding to a context other than ABR. This study demonstrates contextual differences in students’ natural selection ideas and provides implications for natural selection instruction. While ABR is a compelling issue to contextualise natural selection instruction, it may be problematic. 相似文献

This study examines cognitive and social processes in group interactions that shape collaborative learning in science classrooms. Three small groups of students were observed while working collaboratively on explaining the burning of a candle under a jar. The learning environment served as a context for examination of conceptual convergence, a process wherein students construct shared meanings for science concepts through gradual refinement of ambiguous, partial meanings presented in group space. Despite engaging in the same activity with very similar instructional supports, the groups displayed very different patterns of interaction and achieved varied degrees of conceptual convergence. One group collaborated effectively and displayed evidence of individual conceptualizations of science content converging to establish a more well‐informed shared conceptualization. The other groups were not as successful, each for unique reasons. Problems demonstrated in one group included lack of self‐confidence, poor monitoring of group learning, and active avoidance of potentially fruitful conceptual conflicts. The other group struggled primarily because of a combative social context. The major educational significance of this study was the identification of social context and interactive patterns, group approaches to conceptual conflicts, and instructors' roles in collaborative activities as crucial aspects of productive group learning. © 2007 Wiley Periodicals, Inc.

The purpose of this study is to contribute to a theoretical knowledge base through research by examining factors salient to science education reform and practice in the context of socioscientific issues. The study explores how individuals negotiate and resolve genetic engineering dilemmas. A qualitative approach was used to examine patterns of informal reasoning and the role of morality in these processes. Thirty college students participated individually in two semistructured interviews designed to explore their informal reasoning in response to six genetic engineering scenarios. Students demonstrated evidence of rationalistic, emotive, and intuitive forms of informal reasoning. Rationalistic informal reasoning described reason‐based considerations; emotive informal reasoning described care‐based considerations; and intuitive reasoning described considerations based on immediate reactions to the context of a scenario. Participants frequently relied on combinations of these reasoning patterns as they worked to resolve individual socioscientific scenarios. Most of the participants appreciated at least some of the moral implications of their decisions, and these considerations were typically interwoven within an overall pattern of informal reasoning. These results highlight the need to ensure that science classrooms are environments in which intuition and emotion in addition to reason are valued. Implications and recommendations for future research are discussed. © 2004 Wiley Periodicals, Inc. J Res Sci Teach 42: 112–138, 2005 相似文献
