项目摘要

Although a lot of optical and magnetic technology is used, students in primary and secondary schools as well as universities haven't had opportunities for learning the phenomena that are the bases of technology. We proposed teaching materials for demonstrating the interactions between light and substances. Four topics were taken up. Three of them are for direct observations of optical phenomena and the other is an application in electromagnetic experiments.Coloring of polymer sheets using polarizing plates is attractive to school students because of its simple construction and easy change of color. This system can be expanded into a university student experiments taking account of the spectroscopy. We proposed a learning program of spectroscopic experiments using polarizations. One of the basic concepts of light is the law of refraction. We made demonstrative materials for understanding this law. This idea is based on change of the phase velocity of light in substances and the incident and refracted angles can easily be visualized. An application of Michelson interferometer was discussed to detect weaker interactions between light and substances. There are many essential parts to be perform in this experiment. Starting with construction of the system, students are expected to learn the use of light sources, detectors and electric circuits and to master skills to acquire and analyze data. Teaching materials for electromagnetic fields and waves are considered in a developmental stage. A program for understanding magnets and linear motors are introduced. Students of school education made teaching materials by themselves and practiced this program in a friendship project.

虽然使用了大量的光和磁技术，但中小学和大学的学生还没有机会学习作为技术基础的现象。我们提出了演示光与物质相互作用的教材。讨论了四个专题。其中三个是直接观察光学现象，另一个是在电磁实验中的应用。使用偏振片对聚合物片着色，由于其结构简单，易于改变颜色，对学生很有吸引力。该系统可以扩展为大学生的光谱学实验。我们提出了一个利用偏振光谱实验的学习计划。光的基本概念之一是折射定律。我们制作了理解这一规律的示范材料。这种想法是基于物质中光的相速度的变化，并且入射角和折射角可以很容易地可视化。讨论了迈克尔逊干涉仪在探测光与物质弱相互作用中的应用。在这个实验中有许多重要的部分要做。从系统的构建开始，学生将学习光源，探测器和电路的使用，并掌握获取和分析数据的技能。电磁场和电磁波教材处于发展阶段。介绍了一个理解磁体和直线电机的程序。学校教育的学生自己制作了教材，并在一个友谊项目中实践了这一方案。
