教师要抓好教学,学生要学好数学,提高数学教学质量,巩固练习是必不可少的基本环节。练习课,是以巩固、深化学生对知识的理解,形成解题的技能技巧,以发展学生思维能力为重要任务的课。在数学教学中,往往在新授课后,要安排一节或两节练习课,而练习在某种意义上说就意味着知识的重复。怎样做到知识既有重复,又不是机械的简单重复?
Teachers should do a good job of teaching, students should learn math, improve the quality of math teaching, and consolidate the practice is an essential basic link. Practice class is to consolidate and deepen students’ understanding of knowledge, skills and skills to solve problems, to develop students thinking ability as an important task of the class. In mathematics teaching, it is often necessary to arrange one or two practice sessions after the new lectures, and exercises in a sense mean repetition of knowledge. How to do both knowledge, but not a simple mechanical repeat?
