一、背景分析众所周知,初中数学课堂教学的过程应该是师生互动的过程。师生互动在于解决问题,而数学问题是沟通师生互动的载体。这里的问题,就学生的学习内容而言就是学习材料,即在数学教学过程中,教师为了让学生更好地认识和掌握新知、更好地提高数学思维、更好地完善自我价值观而选择与创设的数学学习材料,包括数学课堂提问、数学活动、数学例题和试题。要使课堂 First, the background analysis As we all know, junior high school mathematics classroom teaching process should be teachers and students interaction. The interaction between teacher and student is to solve the problem, while the mathematical problem is the carrier to communicate the interaction between teacher and student. The problem here is learning materials in terms of students’ learning content. In the process of mathematics teaching, teachers choose and Created math learning materials, including math classroom questions, math activities, math examples and test questions. To make the class
