本节内容是七年级第二学期学习了平行线、三角形及其等腰三角形之后所要上的《等腰三角形的复习》一课,通过这节课的实践我认识到上好几何复习课的关键就是要把握好题目的设置,那么如何科学有效地设置题目呢?首先要好好研究教材,吃透教材,然后会活用教材,结合学生的认知情况设置出符合学生实际水平的题目。本文就以两个班级不同的例题设计来谈一谈几何复习课中题目设置存在的问题和有效性策略。
This section is the seventh semester of the seventh grade learning parallel lines, triangles and their isosceles triangle after the “isosceles triangle review” lesson, through the practice of this lesson I realized that the key to good geometry review class Is to grasp the subject set, then how to set the subject scientifically and effectively? First of all to study the textbook, thoroughly through the textbook, and then will use the textbook, combined with the cognitive situation of students to set the issue in line with the actual level of the student. In this paper, two classes of different examples designed to talk about geometry review questions set the problems and effectiveness of the strategy.
