物理解题过程可简单地分为“分析”“表达”和“演算”三个环节,其中“分析”是整个解题过程的基础环节;“表达”是关键环节,其地位相对重要一些;但不可否认,“演算”有时候也会成为解题成败的关键因素.因此教师在教学中,除需加强基本物理知识、物理方法和物理思想外,还应注意通过典型例题剖析,强化 The problem-solving process of physics can be divided into three parts: “analysis ” “expression ” and “calculus ”, in which “analysis ” is the basic part of the whole problem solving process; “expression However, it is undeniable that ”calculus" can sometimes become a key factor in the success or failure of a problem.Therefore, in the teaching of teachers, in addition to strengthening the basic physical knowledge, physical methods and physical thinking, Should also pay attention to the typical example analysis, strengthening
