习题讲评课是课堂教学的一种常见而又重要的课型。由于主客观的原因导致实际教学中许多数学教师对习题讲评课不够重视,大多数教师习惯于就题论题,表面解决,使习题讲评课低效乏味。为提高数学习题讲评课的有效性,文章从习题讲评课前的认真准备,课堂上的精心讲解,课后布置相关作业、巩固讲评效果等方面进行阐述。以上教学活动既能使教师及时而准确地做好查漏补缺的工作,又能使学生互相启迪,优化思维,总结规律,提高分析问题和解决问题的能力。
Exercises Commentary class is a common and important lesson in classroom teaching. Due to the subjective and objective reasons, many math teachers in practical teaching do not pay enough attention to the exercises. Most teachers accustomed to solving the problems and solving the problems ineffectively. In order to improve the effectiveness of the lectures on mathematics exercises, the article elaborates on the preparation of exercises, the meticulous preparation in class, the careful explanation in class, the homework assignments after class, and the reinforcement of the commenting effect. The above teaching activities not only enable teachers to make timely and accurate work of finding out missing and missing, but also enable students to enlighten each other, optimize thinking, summarize laws, and improve the ability to analyze and solve problems.
