1　引言解题教学是数学教学永远的主题 ,很多教师把解题教学等同于“题型 +技巧”教学 ,让学生机械模仿 ,大量重复 ,搞题海战术 .此种教学“虽然能够巩固所学的知识 ,也能加强基本方法的训练 ,但忽视了解题目标、过程的分析 ,以及解题中数学思维方法的培养 ,学生缺乏独立开拓创 1 Introduction The problem-solving teaching is always the subject of mathematics teaching. Many teachers equate the problem-solving teaching with the “type + skill” teaching, allowing the students to imitate mechanically, repeating a lot, and pursuing the sea tactics. Such teaching “is able to consolidate what is learned. The knowledge can also strengthen the training of the basic methods, but ignoring the analysis of the title and the process of the problem, as well as the cultivation of the mathematical thinking methods in solving the problems, the students lack independent innovation and innovation.
