分类讨论思想在中考数学中的应用摘要 本文主要研究了分类讨论思想在中考数学中的应用，首先提出分类讨论思想的概念并且强调了中学生学习分类讨论思想的原因，接着阐述了分类讨论思想的几个基本的要点：本质、原则、较强的逻辑性和解题步骤以及分类讨论思想的意义，然后归纳并总结出分类讨论思想在不同的中考数学题型中的解题方法，通过举例说明对于不同的分类讨论思想的中考数学题型对应的解题方法也大不相同。而本文中所归纳的是中考数学中常见的几类蕴含分类讨论思想的数学题型，对于每类题型提供了有效的解决方法，帮助中学生较好的掌握。最后提供了关于分类讨论思想的一些学习方法和教学建议。中学生在解答复杂的数学问题时,运用分类思想,将复杂的问题进行分类，分类成一个个小问题，并对所有的小问题逐一解决，有利于将复杂的问题变得简单,方便解答。有利于培养学生良好的数学思维习惯，激发中学生学习数学的兴趣，从而提高学生解决数学问题的能力。关键词 分类讨论 思维能力 中考数学The Application of Classified Discussion Thought in Mathematics of Senior High School Entrance ExaminationAbstract This paper mainly studies the application of classified discussion thought in mathematics for senior high school entrance examination. Firstly, it puts forward the concept of classified discussion thought and emphasizes the reason why middle school students study classified discussion thought. Secondly, it expounds several basic points of classified discussion thought: essence, principle, strong logicality, problem-solving steps and significance of classified discussion thought. Finally, it sums up and summarizes the problem-solving methods of classified discussion thought in different types of mathematics for senior high school entrance examination. Through examples, it illustrates that the corresponding problem-solving methods for different types of mathematics for senior high school entrance examination are also quite different. However, what is summarized in this article is several types of mathemat...
