复习课和试卷讲评课是数学教学的主要课型。教师在平时教学中,普遍存在只重视复习课教学设计和阶段性检测,而试卷讲评课因没形成有效地固定模式,备课的随意性强,让很多老师只是和学生简单地对对答案,或又讲得过细,效率不高。其实,试卷讲评课不仅仅是澄清正误,分析试题,也能突破难点,诊断纠错,提升思维,点拨解题思路和技巧,既是对已学知识的归纳延伸,更是对新知学习的有益铺垫。一试卷讲评的目的 Review classes and papers Commentary class is the main class of mathematics teaching. Teachers usually pay attention only to the teaching design and periodic testing of the reviewing class. Teachers do not form an effective fixed mode because of the lack of an effective fixed mode, and the randomness of preparing lessons makes many teachers simply answer the questions with the students or Speaking too carefully, efficiency is not high. In fact, the papers commentaries not only clarify the correctness of the test, analyze test questions, but also break through the difficulties, diagnosis and correction, improve thinking, tips and skills to solve problems, not only is the induction of knowledge has been extended, it is beneficial to learning new bedding .
