项目摘要

This project builds on previous research by physics educators and cognitive scientists and addresses an important instructional problem in science teaching: how to facilitate the process by which students learn to connect real world phenomena with scientific representations of the phenomena. The domain of focus is geometrical optics and the main population of interest consists of pre-service elementary school teachers. The project activities cover two major areas. The investigations: (1) will develop a general template which will be used for specifying an individuals's mental model about optical phenomena. The template will be used to describe how the physics expert's and students' mental models differ, and also to describe changes in a student's mental model during various phases of instruction. (2) will develop and investigate the effectiveness of an instructional strategy, based upon the psychological principle of simultaneous encoding of information, to facilitate students' ability to connect ray diagrams and optical phenomena. In this strategy ray diagram representations will be simultaneously presented with the visual demonstration of the related optical phenomenon. Finally, the investigators will develop a videodisc with a myriad of examples of optical phenomena, and will use the text and graphics overlay capabilities of a computer videodisc system to implement the instructional strategy.

该项目建立在物理教育工作者以前的研究基础上，认知科学家和解决一个重要的教学问题，科学教学：如何促进学生学习的过程将真实的世界现象与科学表征联系起来，现象。聚焦的领域是几何光学，感兴趣的人群包括职前小学教师项目活动包括两个主要领域。调查：（1）将开发一个通用模板，用于指定个人对光学现象的心理模型。该模板将用来描述物理专家和学生的心智模型不同，也可以描述学生在学习过程中心理模型的变化。教学的各个阶段。 (2)将开发和调查教学策略的有效性，基于心理信息同步编码的原则，以便于学生将光线图和光学现象联系起来的能力。在该策略射线图表示将同时提出了相关的光学视觉演示现象最后，研究人员将开发一个视频光盘，光学现象的无数例子，并将使用文本和计算机视盘系统的图形覆盖能力实施教学策略。
