“分类”是一种重要的思维方式,分类可以将研究对象条理化,以利于问题的深入探究。分类的科学性对思维的缜密性、组织性和灵活性提出了较高的要求,自然成了初中数学教学的热点。然而,“分类”教学却存在着不少误区:分类的方式单一、思维固化,缺乏调控意识,过度强化分类导致思维定势等。分类是否必要、是否正确,取决于对数学对象的认识与理解。本文就初中数学教学中分类方式的选择、分类方法的优化、如何看待分类等问题谈 “Classification ” is an important way of thinking, the classification of the object of study can be organized to facilitate the in-depth exploration of the issue. The scientific nature of classification put forward higher requirements on the meticulousness, organization and flexibility of thinking, which has naturally become a hot spot in mathematics teaching in junior high schools. However, there are many misunderstandings in the teaching of “classification”: the way of classification is single, the thinking is solidified, the lack of awareness of regulation and control, the over-intensification of classification leads to the setting of thinking and so on. Classification is necessary and correct, depending on the understanding and understanding of mathematical objects. This article on junior high school mathematics teaching in the choice of classification, optimization of classification, classification and other issues on how to treat
