学习数学离不开解题,解题教学是数学教学的重要组成部分,数学解题大师,陕西师大的罗增儒教授提出了解题教学四部曲:模仿、变式、反思和自觉分析,但笔者认为这是专家给出的解题教学的总纲,并非具体的可操作化的路径,因此结合自己长期的教学实践,针对初中数学解题教学进行了探索,积累了一定的心得体会,本文就是基于实际学情,从教师层面(选编题目和习题的讲解)和学生层面(能力的分层)展开分析,探索
Learning mathematics is inseparable from the problem solving, problem-solving teaching is an important part of mathematics teaching, mathematics problem solving master, Professor Luo Zengru Shaanxi Normal University put forward the problem-solving teaching trilogy: imitation, variant, reflection and conscious analysis, but the author Considering that this is the general outline of problem-solving teaching given by the experts, it is not a concrete operational path. Therefore, based on my long-term teaching practice, this article explores the teaching of junior middle school mathematics problem solving and accumulates some experience. This article is based on The actual situation, from the teacher level (selected topics and exercises to explain) and the student level (ability to stratify) analysis and exploration
