课后练习题是数学教学的一个重要环节,在学生学习过程中有着举足轻重的重要作用,是学生巩固知识、形成技能、培养能力的重要手段。目前的各类教材,在新知的学习之后,都安排了一定量的练习题。但很少有教师去关注那些隐藏在习题背后的有价值的东西,对课后的练习题往往缺乏精心设计和发掘。因此要开动我们的脑筋,对一些练习题进行有效的开发,作比较深入细致的分析研究,充分发掘出习题背后的隐藏价值,让课后练习题真正成为培养学生各方面能力的 After-school exercises is an important part of mathematics teaching, plays an important and important role in the process of student learning. It is an important means for students to consolidate knowledge, form skills and cultivate their abilities. The current types of textbooks, after learning new knowledge, have arranged a certain amount of exercises. However, few teachers pay attention to those valuable things hidden behind the exercises, and often lack of careful design and exploration of the exercises after class.
