初中物理总复习涉及的内容很多,其中基本概念约370多个(包括重要物理量23个),重要规律20个,基本公式42个,主要分组实验23个。复习不能搞成简单的知识重复。心理学研究表明,复习若能在类似材料的学习中进行,通过对新旧材料的比较、分析,就可以使原材料的识记更加精确。因此,总复习采用知识归类、对比是行之有效的方法。一、知识归类 1、按照知识系统归类初中物理分为力、光、热、电四大部分。要为学生理清知识系统,使其掌握知识的内在联系。例如,光学部分的知识系统:
The overall review of junior high school physics involves many topics, including about 370 basic concepts (including 23 important physical quantities), 20 important laws, 42 basic formulas, and 23 main group experiments. Review cannot be a simple repetition of knowledge. Psychology studies show that if the review can be performed in the learning of similar materials, the comparison of the old and new materials can make the memorization of the raw materials more accurate. Therefore, the review of the use of knowledge and comparison is an effective method. First, the classification of knowledge 1, according to the knowledge system categorized junior high school physics is divided into force, light, heat, electricity, four major parts. It is necessary to sort out the knowledge system for students so that they can grasp the inner links of knowledge. For example, the optical part of the knowledge system:
