高中物理对中学生的抽象思维能力有很高的要求,其中摩擦力是力学教学的重点和难点.本文针对中学生在摩擦力理解上的常见错误,提出了利用同构问题法消除相关误解,学生在纠正错误观念的同时,学会新旧知识融合内化的方法.
High school physics has high requirements on middle school students’ abilities of abstract thinking, in which friction is the key and difficult point of mechanics teaching.This paper aims at the common mistakes of middle school students in the understanding of friction, and proposes to eliminate the related misunderstanding by using the method of isomorphism, While correcting the notion of misunderstanding, learn how to integrate internal and external knowledge of old and new knowledge.
