初中数学更多是作为高中数学的一个铺垫,大体上可以分为几个教学模块,分别有方程、几何证明、三角函数、统计学等。在这几个模块中,统计学、三角函数、几何证明只是最初级的介绍,题目难度不大,所考察的数学思想也较为固定。而方程则是学生在小学就已经接触的知识,在初中必然要进行一定的加深,因此,方程及与其相关的知识点,才是初中教学的重点,而谈到方程和演化而来的应用题,分类思想往往会起到很大作用。笔者认为,分类思想的教学
Junior high school mathematics as a bedding for high school mathematics, in general, can be divided into several teaching modules, respectively, equations, geometric proof, trigonometry, statistics and so on. In these modules, statistics, trigonometry, geometric proof is only the first introduction, the title is not difficult, the study of mathematical ideas are relatively fixed. But the equation is the knowledge that the students have already contacted in the elementary school, and it must be deepened in the junior middle school. Therefore, the equation and its related knowledge points are the focuses of the junior middle school teaching, but the equation and the evolved application question , Classification ideas tend to play a big role. The author believes that the classification of teaching ideas
