中国物理学家叶企孙教授指出“物理教学不仅要给学生以知识,更要给学生以科学的思想方法”。等效替代法既是科学家研究问题的方法,也是学生在学习物理中常用的方法,新课程标准便要求学生要掌握一些探究问题的物理方法。教师在物理教学中应做到知识传授与方法指导并重。一般来说运用等效方法处理问题的步骤如下:1、分析原事物(需研究求解的物理问题)的本质特性和非本质特性。
Professor Ye Qi-sun, a Chinese physicist, pointed out that “physics teaching not only gives students knowledge but also gives students a scientific way of thinking.” The equivalent substitution method is not only a method for scientists to study the problem, but also a method commonly used by students in studying physics. The new curriculum standard requires students to master some physical methods to explore the problem. Teachers in the teaching of physics should be both imparted knowledge and methodological guidance. In general, the steps to deal with the problem using the equivalent method are as follows: 1. Analyze the essential and non-essential characteristics of the original matter (the physical problem to be studied and solved).
