This project will study learning and teaching processes in several exemplary sciencecurricula in different subject areas. All of them use new approaches to teaching that areunique in the way that they foster active learning of conceptual models on the part of thestudent. At present many of the general principles underlying the learning that occurs inthese lessons are poorly understood. However, advances in cognitive science haveproduced a very promising new theory of model-based learning which can help toanalyze and describe these teaching techniques. The investigators will use acombination of qualitative and quantitative methods to study these innovative units andanalyze them using these new cognitive science concepts. The overall goal is to findprinciples of instruction for developing students' visualizable models in science. Centralto the project will be case studies of skilled teachers who are adept at fostering modelconstruction by students. The problem is to identify the strategies by which teachers areable to do this. The project will analyze teaching strategies and resulting student learningprocesses in detail using protocol analysis techniques. Follow up studies will makequantitative comparisons between groups that complement the qualitative case studies,and pre and post testing will measure the size of learning gains in different areas. In a second part of the project, key elements of model-based learning theory will be elaborated via the analysis of expert learning protocols. Similarities and differences between expert and student processes will be examined that highlight new ways of understanding student learning processes that suggest new teaching strategies.

该项目将在不同学科领域的几个模范科学典范中研究学习和教学过程。他们所有人都使用新的方法来进行教学，这些方法是通过他们促进概念模型的积极学习方式的方式。目前，在这些课程中进行学习的许多一般原则对这些课程的理解很少。但是，认知科学的进步已经生成了一种非常有前途的基于模型的学习理论，可以帮助展景观和描述这些教学技术。研究人员将使用定性和定量方法的结构来研究这些创新的单元，并使用这些新的认知科学概念对其进行了分析。总体目标是为开发学生在科学中的可视化模型找到教学的普通。该项目将是熟练的教师的案例研究，他们擅长促进学生的模型结构。问题是要确定教师在该策略中实现这一目标的策略。该项目将使用协议分析技术详细分析教学策略和导致的学生学习过程。后续研究将在补充定性案例研究的小组之间进行精心的比较，并且在测试前后，将衡量不同领域的学习收益的规模。 在项目的第二部分中，将通过分析专家学习协议来详细阐述基于模型的学习理论的关键要素。 将研究专家和学生流程之间的相似性和差异，这些方法强调了理解学生学习过程的新方法，这些方法提示了新的教学策略。
