“提高课堂效率,减负增效”是当前教育工作的一项基本要求.新课改下的物理课堂教学已有了很大的进步,但还不同程度存在着教师教得很辛苦,学生学得很痛苦的现象,如这一问题得不到很好的解决,减负增效就会变成空话.因此深入探讨提高课堂效率的途径和方法势在必行.下面就如何提高物理课堂效率、减负增效谈谈笔者的认识. “Improving Classroom Efficiency, Reducing Burden and Increasing Efficiency” is a basic requirement of current educational work.Physical classroom teaching under the new curriculum reform has made great strides, but to a certain extent, teachers have taught very hard that students Learn the very painful phenomenon, if this problem can not be solved well, the negative effects will become empty talk.Therefore it is imperative to explore in depth the ways and methods of classroom efficiency.Therefore how to improve the efficiency of physics classroom , Reduce the negative effect to talk about the author’s understanding.
