In this paper we explore the relationship between learning gains, measured through pre‐assessment and post‐assessment, and engagement in scientific argumentation. In order to do so, this paper examines group discourse and individual learning during the implementation of NASA Classroom of the Future’s BioBLAST!® (BB) software program in a high school biology classroom. We found that the argumentative structures, the quality of these structures, and the identities that students take on during collaborative group work are critical in influencing student learning and achievement in science. We provide recommendations for instructors implementing argumentation in their science classrooms, and provide suggestions for the development of future research in this area. 相似文献

An assessment‐oriented design‐based research model was applied to existing inquiry‐oriented multimedia programs in astronomy, biology, and ecology. Building on emerging situative theories of assessment, the model extends prevailing views of formative assessment for learning by embedding “discursive” formative assessment more directly into the curriculum. Three twenty‐hour curricula were designed and aligned to content standards, and three levels of assessments were developed and used to assess and enhance learning for each curriculum. These assessments included three or four informal “activity‐oriented” quizzes and discursive formative feedback rubrics supporting collective discourse, a “curriculum‐oriented” examination of individual conceptual understanding, and a “standards‐oriented” test measuring aggregated achievement of targeted standards. After two design‐research cycles, worthwhile scientific argumentation and statistically significant gains were attained for two of the three packages on the exam and test. Achievement gains were comparable to or larger than those of students in comparison classrooms. Many existing innovations could be enhanced and evaluated in this fashion; designing these strategies directly into innovations could have an even greater impact on discourse, understanding, and achievement. © 2012 Wiley Periodicals, Inc.

This study examined the relationship among cognitive and motivational variables impacting college students’ willingness to
take mitigative action to reduce the impacts of human-induced climate change. One hundred and forty college students were
asked to read a persuasive text about human-induced climate change and were pre and post tested on their attitudes about climate
change and their willingness to take action to mitigate its effects. Students showed statistically significant changes in
their attitudes about climate change and their willingness to commit to take action. A path model demonstrated that openness
to change and a willingness to think deeply about issues predicted both change in attitudes and expressed willingness to take
action. This research demonstrates that a persuasive text has the potential to promote change around complex socio-scientific
issues. 相似文献

This study details an innovative approach to coordinating and enhancing multiple levels of assessment and discursive feedback around an existing multi‐media curricular environment called Astronomy Village®. As part of a broader design‐based research programme, the study analysed small group interactions in feedback activities across two design cycles. The goal of this analysis is to develop an understanding of the ways that a situative approach to assessment and practise supports learning. Findings demonstrate ways that student and teacher engagement in collaborative activities support and constrain meaningful understanding, which we consider in terms of a trajectory of participation in and across conversations and written assessments, as well as individual learning gains on formal classroom examinations and standards‐oriented external tests. Analyses of complementary formulations of domain concepts—discourse practises and assessment performance—suggest that participation in social forms of scientific engagement supports both learning and subsequent performance in more formal contexts. We suggest design principles for integrating the formative functions of discursive feedback with the summative functions of traditional assessment, through participation in different forms of science discourse(s). 相似文献

A structural equation model of conceptual change in physics 总被引：1，自引：0，他引：1
A model of conceptual change in physics was tested on introductory‐level, college physics students. Structural equation modeling was used to test hypothesized relationships among variables linked to conceptual change in physics including an approach goal orientation, need for cognition, motivation, and course grade. Conceptual change in physics was determined using gains from pre‐ to post‐administration of the Force Concept Inventory (FCI). Results indicated that need for cognition and approach goals had a significant influence on motivation. Motivation influenced change scores on the FCI both directly, and indirectly, through course grade. Finally, course grade directly influenced conceptual change. The implications of these findings for future research and developing students' conceptual change in physics are discussed. © 2011 Wiley Periodicals, Inc. J Res Sci Teach 48: 901–918, 2011 相似文献

For the past 10 years the Ministry of Education of Mongolia has periodically oscillated between decentralization and recentralization policies. On paper, it has consistently and enthusiastically subscribed to decentralization, but in practice has given these policies low priority. This study attempts to explain the discrepancies between policy talk and actual implementation. Methodologically, the authors investigate local policy contexts and examine how international interventions such as decentralization policies are locally reinterpreted or ‘Mongolized’. The study examines several areas where cultural legacies from the socialist past have clashed with the expectations of international donors. Theoretically, the Mongolian fiasco of decentralization reform lends itself as a case to address issues that have been raised both in comparative research on ‘transitology’ and on cross‐national policy borrowing. 相似文献

本文主要以概览的视角回顾了在教育政策借鉴与传播（policy borrowing and lending）研究中的主要议题和趋势。政策借鉴与传播是一个在学术上依托于比较教育学和公共政策学的研究领域。在比较教育学中,针对“旅行式改革”（travelling reforms）、全球化教育政策的探索是一个经久不衰的研究课题。本文主要描述了政策借鉴与传播研究领域的历史,并讨论了四个新的研究趋势：第一,由双边框架向国际标准框架的转变;第二,学者们开始关注各国系统与个案背后的逻辑;第三,政策图景（policyscapes）概念对研究方法论的启示;第四,政策映射研究,即借鉴他国教育政策时的本土解读。 相似文献

We tested a theoretical model of college students’ ratings of messengers of resilience and models of resilience, students’ own perceived resilience, regulatory strategy use and achievement. A total of 116 undergraduates participated in this study. The results of a path analysis indicated that ratings of models of resilience had a direct effect on students’ perceived resilience and that perceived resilience directly influenced regulatory strategy use (i.e. effort regulation, self-regulation and time management), which influenced academic achievement (as measured by grade point average). The implications of our findings are further discussed, along with avenues for future research. 相似文献
