复习教材就可以巩固知识,这是一条数学规律。在复习课上我们常尽可多地讲练数学题目,但是讲练了那么多题目,效率到底如何?是否数量上多多益善,难度上越难越好?如果只是试图让学生见多识广,不触及学习的积极思维,那么这样的数学是低效的甚至是负效的。数学习题,浩如烟海,习题选择过多,学生犹如“题海”中游泳,造成负担过重,结果适得其反。怎么选择习题,提高复习效果呢?本文谈一点认识和体会。一、选择习题的原则初中数学总复习不是旧知识的机械重复,而是引导学生对所学知识进行系统归纳和升华,并用已有的知识解决新问题,进一步加 Reviewing textbooks can consolidate knowledge. This is a mathematical rule. In the review class, we often try to teach mathematics subjects as much as possible, but we have taught so many topics. How effective is this? Is it better to have more quantity? Is it harder to make the better? If you just try to make the students more informed and not touched. Learning positive thinking, then such mathematics is inefficient or even negative. Many mathematics problems are so numerous that many problems are selected. Students are like swimming in the “Title of the Sea,” causing a heavy burden and the result is counterproductive. How to choose exercises and improve review results? This article talks about understanding and understanding. First, the principle of selecting exercises The general review of junior high school mathematics is not a mechanical repetition of old knowledge, but guides students to systematically sum up and sublimate the knowledge they have learned, and use existing knowledge to solve new problems and further increase
