顾名思义,逆向思维是与顺向思维相反的一种思维方式,它是从原问题的相反方向出发,由结果探究原因,由事物的现象去挖掘其本质。小学数学因其别于其他科目的极强的逻辑性和一些概念、性质、运算、思路及方法的可逆性,决定了学生需要具备一定的理解数学可逆性的能力,即需要具备一定的逆向思维的能力。然而现实生活中,许多学生仍然保持着顺向思维的习惯,不会变通地思考问题,这种思 As the name implies, reverse thinking is a way of thinking which is the opposite of forward thinking. It starts from the opposite direction of the original problem, explores the reason from the result, and excavates its essence from the phenomena of things. Because of its strong logic and its reversibility of some concepts, properties, operations, ideas and methods, elementary mathematics determines that students need to have a certain ability to understand the mathematical reversibility, that is, they need to have some backward thinking Ability. However, in real life, many students still maintain the habit of thinking forward without thinking about the problem in a flexible way.
