学生是教学的主体,对于习题教学亦不能外,但是学生练什么?按照怎样的顺序练习?解题过程中思维遇到了困难怎么办?这些都需要我们教师充分发挥主导性作用进行宏观调控.习题课是高中数学重要的课型,传统的习题教学就题讲题,灌输解题的方法和技巧,导致学生的思维主动性不够,知识学习和应用不成体系,解决问题的能力得不到有效的提升.那么在高中数学习题教学中,如何发挥教师的主导性作用呢?本文就该话题谈几点看法,望能有助于教学实践.一、精选范例深化研究习题教学不可缺失了例题的示范性作用,笔者认为选择怎 Students are the main body of teaching and cannot be used for exercises. However, what are the students practicing? What kind of exercises should be performed in accordance with the sequence? What should be done when thinking in the process of solving problems? These need our teachers to give full play to the dominant role of macro-control. Classes are important classes for senior high school mathematics. The traditional problem-solving exercises are problem-solving topics and inculcating methods and techniques for problem-solving. As a result, students’ initiative in thinking is not enough, knowledge learning and application are not systematic, and the ability to solve problems is not effectively Promote. Then how to play the leading role of teachers in the teaching of high school mathematics problems? This article discusses several points of view on this topic, hope can help teaching practice. First, select examples to deepen research exercises teaching can not miss the example of The exemplary role, the author thinks how to choose
