还原法在数学解题教学中的应用探究

Exploration of the Application of Reduction Method in Mathematical Problem-solving Teaching

还原法是数学学习中非常重要的一种方法,对帮助学生掌握数学思想、提高学生数学素养有很大的作用。运用还原法解决数学问题时,要针对不同类型的问题使用不同的方法:单个对象--循序渐进,多个对象--明确关系,对象有定有变--确定核心,再次还原--验证答案。

Reduction method is a very important method in mathematics learning, which plays a very important role in helping students master mathematics thought and improving their mathematics accomplishment. When using reduction method to solve mathematical problems, different methods should be used for different types of problems as follows: single object--step by step, multiple objects--define the relationship, object defined and changed--determine the core, reduction again --verify the answer.
