例题教学是数学复习教学的主要组成部分,能起到引导、归纳和示范的作用.目前的初三数学复习教学中,仍存在因教师例题设计不恰当而导致课堂效率低下的现象,使得面临中考的学生们依然深陷题海.笔者发现,初三学生在解题中常常出现解题不严谨、解法不简便、难题不敢想、变式不会做等问题.为帮助学生解决上述问题,笔者对初三数学复习教学中的例
Example teaching is the main component of mathematics review teaching. It can play the role of guidance, induction, and demonstration. In the current third-year mathematics review teaching, there is still the phenomenon of classroom inefficiency due to inappropriate teacher example design, which makes the face of the examination. The students are still deeply in the sea of questions. The author finds that junior high school students often have problems in the problem solving, such as rigorous problem solving, inconvenient solution, difficulty in thinking and change, and so on. To help students solve the above problems, The author’s example of mathematics review in junior high school
