逆向思维是一种创造性思维.在数学学习中,适当运用逆向思维,往往能使许多问题简单化.在数学教学过程中,当学生理解了某个定理、概念后,如果加以适当的逆向思维训练,往往会引导学生跨进新的知识领域,提高学生的创新意识.本文分析了阻碍学生逆向思维的原因,结合一些具体事例,阐述如何在数学学习中运用逆向思维解决问题.一、阻碍学生逆向思维的因素1.教学形式的原因传统的数学教学模式,一般遵循“定理的建立——定理的证明——定理的运用”三个部分,学生习惯了教师引导的正向思维,不加以引导,很难将正向思维转向逆向思维.2.思维过程的原因 Reverse thinking is a kind of creative thinking.In mathematics study, proper use of reverse thinking often can simplify many problems.In mathematics teaching process, when students understand a certain theorem, the concept of appropriate reverse thinking training , Often lead students into new areas of knowledge and improve students ’innovative awareness.This article analyzes the reasons that hinder students’ reverse thinking, and combines some concrete examples to explain how to use reverse thinking to solve the problem in mathematics learning.One, hinder students to reverse Factors of thinking 1. The reason of the teaching form The traditional mathematics teaching mode generally follows “the establishment of the theorem - the proof of the theorem - the application of the theorem”. The students are accustomed to the positive thinking guided by the teacher, Guide, it is difficult to forward thinking to reverse thinking .2 reason of thinking process
