一、设计能引起学生思考与猜想的问题问题是数学的心脏。在数学教学中,从课堂提问到新概念的形成与确立、新知识的巩固与应用、学生思维方法的训练与提高以及实际应用能力和创新能力的增强,无不是从“问题”开始的。对于数学中的一些概念、性质、法则、公式等新知识的学习,教师应结合具体的学习内容,设计能引导学生通过思考,产生认知冲突从而进行猜想的问题。
First, the design can cause students to think and guess the problem The problem is the heart of mathematics. In the teaching of mathematics, from the classroom questioning to the formation and establishment of new concepts, the consolidation and application of new knowledge, the training and improvement of students’ thinking methods, and the enhancement of practical application ability and innovation ability, all from “question” . For some new concepts in mathematics, such as the nature, rules and formulas, teachers should combine specific learning content to design questions that can guide students to think and generate cognitive conflicts through conjecture.
