一、化归思想概述(一)化归思想简介数学思想方法是数学知识的重要组成部分,也是数学教学的主要内容,化归思想是数学教学中常用的思想方法。在数学思想方法中,化归思想法的教学是重点,其应用远比其他数学思想方法广泛。化归思想的根本特征:在解决一个复杂问题时人们的眼光并不落在问题的结论上,而是去寻觅、追溯一些熟知的结果,尽管向前走两步,也许能达到目的,但我们也情愿退一步回到原来的问题上去。(二)化归方法的运用 I. Overview of the thought of returning to the past (1) Introduction to the thought of returning to the past Mathematical thinking is an important part of mathematics knowledge. It is also the main content of mathematics teaching. The thought of returning to normalization is a common way of thinking in mathematics teaching. In mathematics method, the teaching of returning to thought method is the key point, and its application is far more extensive than other mathematical methods. The basic characteristics of the thought of return to nature: When looking at a complex issue, people’s eyes do not fall on the conclusion of the problem. Instead, they seek out and trace some well-known results. Although two steps can possibly achieve their goal, we Also willing to take a step back to the original question.
