如何提高课堂教学效率,是每一位高中数学教师不断探索的课题,而课堂知识讲解是贯穿数学教学的重要渠道。在实际的课堂教学活动中不难发现,高效率的数学课堂是一个可以将知识动态演变的过程,课堂教学中的很多环节其实是教师在备课时根据教材内容和学生的学习情况设计而成的,而这些设计环节都可以在教学活动中衍生成为一种生成性的教学资源。这些资源,有些是能够扭转被动的教与学的局面,甚至能激活教与学,从而让师生双方的课堂质效成倍提升。
How to improve classroom teaching efficiency is a topic that every high school mathematics teacher continues to explore, and classroom knowledge explanation is an important channel through mathematics teaching. In the actual classroom teaching activities, it is not difficult to find that an efficient mathematics classroom is a process that can dynamically evolve knowledge. Many aspects of classroom teaching are actually designed by teachers based on the content of the teaching materials and the learning situation of students. These design links can be derived from teaching activities as a kind of generating teaching resources. Some of these resources can reverse the passive teaching and learning situation, and can even activate teaching and learning, so that the effectiveness of the classroom between teachers and students can be doubled.
