复习课(单元复习、学期复习、毕业复习)不是对已学过知识的简单重复,而是对这些知识有所系统和加深。根据学生实际情况,精心选择例题和习题,引导学生掌握解题规律,是复习课的主要任务。今以代数证明题复习课为例,说明如下。许多学生做代数证明题,总是零敲碎打,东碰西撞,无章可循。针对这种情况,我们注意引导学生通过复习掌握某类代数证明题的规律。开始,先让学生做两个练习题,学生是这样解的: The review class (unit review, semester review, graduation review) is not a simple repetition of learned knowledge, but rather a systematic and deepening of this knowledge. According to the actual situation of students, careful selection of examples and exercises to guide students to master the law of problem solving is the main task of the review class. This is an example of an algebraic proofreading class. Many students do algebraic proofs. They are always piecemeal, hitting the east and west, and there is no rule to follow. In view of this situation, we pay attention to guide students through the review of a certain type of algebraic proof of the law. At the beginning, let the students do two exercises. The students do the following:
