极值问题是中学物理教学中常见的、也是学生难于掌握的问题。虽然此类问题在初中物理教学中研究不多,但是如果适当地研究些简单的极值问题,让初中学生尽早了解这类问题的分析方法,这对加滚理解物理知识和培养学生的思维能力都是颇有裨益的。下面通过几例的分析谈谈我初浅的认识。 The problem of extreme value is a common problem in middle school physics teaching and it is also difficult for students to master. Although this type of problem has not been studied in junior high school physics teaching, if we properly study some simple extremum problems, let junior high school students understand the analysis methods of this type of problem as early as possible, which will help students understand physics knowledge and cultivate their thinking ability. It is all very helpful. Let’s talk about my early understanding through the analysis of several cases.
