变式与质疑是数学教学中常用的两种教学方式。在运用时，教师要抓住教材中典型问题变式，开拓学生思路；对学生的众多解法或问题本身，要引导学生反思总结，发现新东西。 创新的前提是必须具备良好的发散性思维，即要求从不同角度、不同层面思考问题，培养学生思维的敏捷性
Variant and questioning are two kinds of teaching methods commonly used in mathematics teaching. In use, teachers should grasp the typical problem variants in the teaching materials and open up student ideas. To students’ numerous solutions or problems themselves, they should guide students to reflect and summarize and discover new things. The premise of innovation is to have good divergent thinking, that is, to ask questions from different angles and levels, and to cultivate the agility of students’ thinking.
