化归思想不仅是一种重要的解题思想方法,也是一种最基本的思维策略。所谓化归思想方法,就是在研究和解决有关数学问题时采用某种手段将问题通过变换使之转化,进而达到解决的一种方法。一、把握基础,遵循原则,在实践中认识化归原理在学习过程中,学生应当注意结合基础知识,在实践中逐渐认识化归思想,学生通过遵循以下几个原则,能更好的体会数学学习中化归思想的运用1、遵循熟悉化原则:即化陌生为熟悉比如,求n边形的内角和。在教学过程中,教师可以让学生回顾一下三角形的内角和,学生可以很熟练的答出结果,三角形内角和等于180°;接着引导学
To return to thinking is not only an important method of thinking and solving problems, but also a most basic thinking strategy. The so-called way of thinking, is to study and solve the mathematical problems using some means to transform the problem to transform, so as to achieve a solution. First, grasp the foundation, follow the principle, in principle, understanding of the principle of return In the learning process, students should pay attention to combining basic knowledge, in practice gradually recognize the idea of return to normal, students follow the following principles, to better understand mathematics Learning to use the idea of change 1, to follow the principle of familiarization: that is unfamiliar to be familiar with, for example, the inner angle and n polygons. During the teaching process, the teacher can ask the students to review the interior angles of the triangle, and the students can learn the result very well. The interior angles of the triangle are equal to 180 °.
