Teaching for conceptual understanding and self-regulation through collaborative problem solving

9353099安德森计划是一项为期三年的科学协作问题解决调查，目的是发展中学生学习和解决问题的账户，并制定教学策略和材料，以提高学生对科学的概念理解和在复杂问题解决情景下的自我调节能力。第一年是一项干预研究，调查了三种教学条件的比较效果：a)中介独立问题解决，b)集体问题解决，c)中介集体问题解决。这项调查将在八个教室进行，学生们学习一个关于物质的性质和性质的单元。对一年级数据的分析将在第二年进行，目的是：a)评估在概念理解、自我调节能力和三种条件下实践的社会规范的内化方面，在各种条件下取得预期结果的成功情况；b)评估结果的原因，主要是通过课堂互动的微观分析；以及c)修订教学程序。在第三年，我们将调查修订后的教学计划在八个教室的实施情况。这项拟议的研究将有助于研究科学中的问题解决和概念理解，并有助于改善教育实践，重点是教师和学生在“学习社区”中共同工作的机会。

9353099 Anderson The project is a three year investigation of collaborative problem solving in science for the purpose of developing accounts of learning and problem solving by middle school students and developing instructional strategies and materials that improve both students' conceptual understanding of science and their capacities for self-regulation in complex problem solving situations. Year 1 is an intervention study investigating the comparative effects of three instructional conditions: a) mediated independent problem solving, b) group problem solving, and c) mediated group problem solving. This investigation will be conducted in eight classrooms as the students study a unit on the nature and properties of matter. Analyses of Year 1 data will occur in Year 2 for the purpose of: a) evaluating the success with which the desired outcomes were achieved across the various conditions in terms of conceptual understanding, self-regulatory abilities, and internalization of the social norms practiced across the three conditions, b) evaluating the reasons for the outcomes, principally through microanalysis of classroom interactions, and c) revising the instructional procedures. In Year 3, we will investigate the implementation of the revised instructional program in eight classrooms. The proposed study will contribute both to research on problem solving and conceptual understanding in science and to the improvement of educational practice, focusing on the opportunities for teachers and students to work together in "learning communities." ***
