数学课堂教学的本质是教数学思维过程,而思维过程首先是解决问题的过程,故思维通常是有问题情境产生的,而且是以解决问题情境为目的的。故在课堂中创设问题情境是数学课堂培养学生思维内在的要求。数学课程标准也强调数学教学应从学生实际出发,创设有助于学生自主学习的问题情境,引导学生通过实践、思考、探索、交流,获 The essence of mathematics classroom teaching is to teach mathematical thinking process, and thinking process is the first to solve the problem process, so thinking is usually a problem situation, but also to solve the problem situation for the purpose. Therefore, the creation of problem situations in the classroom is an inherent requirement of students’ thinking in mathematics classroom. Mathematical curriculum standards also emphasize that mathematics teaching should proceed from the students’ reality and create problem situations that help students to learn independently. Students should be encouraged to practice, think, explore, exchange and obtain
