著名数学家波利亚说过:数学问题的解决仅仅只是一半,更重要的是解题之后的回顾与反思.解题是数学学习的一个核心内容和一种最基本的活动形式,让学生在掌握基础知识、基本技能的前提下,培养学生的数学创新能力、探究能力,是新课程标准的重要指示.初中数学要想取得理想的教学效果,教材所提供的“母题”的教学功能与作用不可小视.下面就课本的习 Polya, a famous mathematician, said: The solution to the problem of mathematics is only half, more importantly, it is the retrospect and reflection after the problem solving. Problem solving is a core content of mathematics learning and a most basic form of activity, Master the basic knowledge and basic skills under the premise of training students in mathematical innovation ability to explore the new curriculum standards is an important indicator of junior high school mathematics want to achieve the desired effect of teaching materials provided by the “motif” teaching Functions and functions can not be ignored. The following textbook learning
