一、问题的提出高三下学期,许多学校的数学复习课都以综合训练为主,通过讲练达到复习的目的。数学讲评课是数学教学的重要环节,其目的是反馈测试评价的结果,让学生了解自已的知识、能力水平,弥补缺陷,纠正错误,完善知识系统和思维系统,提高分析和解决问题的能力。但在讲评课上,老师往往讲得一身汗,学生却兴趣索然,已会的内容不想听,不会的内容则因讲评的不详细,收效甚微。实践表明,要提高讲评课的效率,必须发挥学生的主观能动性,充分做好课前准备。
First, the problem raised The second semester, many schools of mathematics review classes are based on comprehensive training, through practice to achieve the purpose of review. The purpose of mathematics teaching and assessment is an important part of mathematics teaching. Its purpose is to feedback the result of the test and evaluation so that students can understand their own knowledge and abilities, make up defects, correct mistakes, improve knowledge system and thinking system, and improve their ability to analyze and solve problems. However, in the commentary class, the teacher often speaks a sweat, but students are naturally interested in the content that they already do not want to hear. The content that is not due to the comment is not detailed, with little effect. Practice shows that in order to improve the efficiency of teaching assessment, we must give full play to students’ subjective initiative and fully prepare for the lesson.
