分类讨论思想是中学数学教学中要求学生重点掌握的四种数学思想方法之一.但学生在解决相关问题时,常常感觉比较困难且易出现错误.因此尽量简化讨论.要做到这一点,就要仔细观察题目中隐含信息,充分挖掘数学问题中潜在的特殊性,打破常规,从而简化,甚至避免讨论.本文介绍几种处理分类讨论问题的非常规策略,供大家参考. The idea of ​​classifying and discussing is one of the four mathematics and thinking methods that students are required to master in mathematics teaching in middle school. However, students often find it difficult and error-prone to solve related problems. Therefore, simplify discussion as much as possible. To achieve this, It is necessary to carefully observe the implicit information in the topic and fully exploit the potential particularities of mathematical problems, break the conventions, simplify and even avoid discussion. This article describes several unconventional strategies for dealing with the issues of classification and discussion for your reference.
