物理学是一门比较抽象难懂的科学,所包含的内容极其丰富.物理学的许多基本概念、定律、定理需要学生准确掌握,以备后继学习之用.为了使学生顺利理解和掌握其中的物理精髓,物理实验,尤其是演示实验在物理教学过程中的有效运用是必不可少的.课堂演示实验是配合课堂教学的一种手段.教师结合课堂教学,或者让学生观察某些实验现象,然后引导学生总结规律;或者先讲理论,然后做演示实验来验证;或者课后让学生到实验室看实验表演,这些都是常用的、可行的做法.然而,延时演示的效果不如即时表演,而购买昂贵的仪器又常常受到经费的限制,CAI在此领域正好可以弥补许多不足.
Physics is a relatively abstract and difficult science, and it contains extremely rich contents. Many basic concepts, laws, and theorems of physics need students to master it accurately in order to prepare for subsequent learning. In order to enable students to understand and master the Physical physics, physical experiments, especially demonstration experiments, are indispensable for effective use in the physics teaching process. Classroom demonstration experiments are a means of cooperating with classroom teaching. Teachers combine classroom teaching or allow students to observe certain experimental phenomena. Then guide the students to sum up the rules; either first discuss the theory and then do the demonstration experiment to verify; or let the students go to the lab to see the experimental performance after class. These are common and feasible methods. However, the delayed demonstration is not as effective as the real-time performance. , And the purchase of expensive instruments is often limited by funding, CAI in this area can just make up for many deficiencies.
