逆向思维指的是不按照给出条件的先后顺序,从结果或者反方向出发,对问题进行逆向推理的一种思维方式。逆向思维是小学数学中常用的一种解题方法,能够起到发散思维、培养数学思考能力、提高数学素质的作用,对小学生理解数学问题、解决数学问题的关键途径。本文结合教学实际,以苏教版教材为例,分析了逆向思维在小学数学解题中的应用方法及效果,希望能够为培养小学生的创新能力提供一些参考。
Reverse thinking refers to a way of thinking that does not follow the order of given conditions and proceeds from the result or the opposite direction to reverse reasoning on the question. Reverse thinking is a commonly used method of solving problems in primary school mathematics. It can play a key role in helping pupils understand mathematics problems and solve mathematical problems by diverging their thinking, cultivating their mathematical thinking skills, improving their mathematical qualities. Based on the teaching practice, this paper analyzes the application methods and effects of reverse thinking in elementary mathematics problem solving, and hopes to provide some reference for cultivating the innovative ability of primary school students.
