目前,课堂教学的改革正呈蓬勃发展的势态,并取得了显著成果,然而,在教改实践中仍存在一些问题和误区,从而对学生思维能力的培养以及帮助学生理解数学本质造成了限制,本文将根据笔者掌握的情况和研究体会,谈谈高中数学课堂教学改革中存在的几个误区并加以分析,期待能起到抛砖引玉的作用,引发同行对数学教学的思考.1学生活动过于浅层化,无法形成有效的思维活动学生活动的设计是教学设计的重要组成部分, At present, the reform of classroom teaching is developing vigorously and has achieved remarkable results. However, there are still some problems and misunderstandings in the practice of teaching reform, which limits the cultivation of students’ thinking ability and helps students understand the nature of mathematics. Based on the situation and research experience of the author, I will discuss some misunderstandings in mathematics classroom teaching reform in senior high schools and analyze them. I look forward to playing a role in attracting students and inspiring peers to think about mathematics teaching. 1 Students’ activities are too shallow. Can not form effective thinking activities. The design of student activities is an important part of instructional design.
