问题解决教学是以学生为主体,学生通过思考、合作交流等方式,在教师的引导下完成从发现问题、提出问题、分析问题和解决问题的教学过程.高中数学课程国家标准研制组组长张奠宙指出,改革我国数学教育的突破口是“以问题解决为主导”.问题解决教学中的“问题解决”与平时经常听到的“解决问题”是不同的.“问题解决”比“解决问题”的教学过程要多一些思维过程和探索过程,它更加强调过程,注重让学生在过程中获得数学解题 Problem-solving teaching is based on students, students through the way of thinking, cooperation and exchange, under the guidance of the teacher to complete the teaching process of finding problems, asking questions, analyzing problems and solving problems. It is pointed out that the breakthrough in reforming mathematics education in our country is that “problem-solving is the dominant factor.” “Problem-solving” in problem-solving teaching is different from “problem-solving” often heard in peacetime. “More than the” problem-solving "teaching process to some more thinking process and exploration process, it is more emphasis on the process, focusing on getting students in the process of solving mathematical problems
