习题是教材的重要组成部分,习题教学是课堂教学中不可忽视的重要环节。通过练习既可以使学生牢固地掌握知识,形成熟练的技能、技巧,还可以在潜移默化中渗透数学思想方法,促进学生数学思维能力的提高。但目前的课堂教学中,对教材习题机械处理、浅显教学或任意改动、盲目拓宽的现象多有存在。那教师应怎样合理使用课本习题,提高习题的有效性呢?下面笔者以课本习题的教学为 Exercises are an important part of teaching materials. Exercises teaching is an important part that can not be ignored in classroom teaching. Through practice can not only enable students to firmly grasp the knowledge, the formation of skilled skills, skills, but also subtle impermeability of mathematical thinking and methods to promote students’ ability to improve mathematical thinking. However, in the current classroom teaching, mechanical processing of teaching materials exercises, shallow teaching or arbitrary changes, there are many blind to widen the phenomenon. How to use the textbooks should be reasonable teacher exercises to improve the effectiveness of the exercises? The following textbook exercises to teach
