问题是数学的核心,数学问题的种类很多,结构比较复杂。所以,我们在解决数学问题的时候,注重化归思想的培养很重要,即把要解决的问题转化为已能解决的问题。本文先介绍化归的方向、原则,再结合例子说明化归方法,从而为中学生的数学学习提供有效而方便的途径。
The problem is the core of mathematics. There are many kinds of mathematical problems and the structure is complicated. Therefore, when we solve the mathematics problem, it is very important to pay attention to the cultivation of the thought of returning to the past, that is, to turn the problem to be solved into the problem that can be solved. This article firstly introduces the direction and principle of the return to naturalization, and then combines the examples to illustrate the method of return to normal so as to provide an effective and convenient way for middle school students to learn mathematics.
