高中物理学习中存在许多易混淆的概念、模型等知识点,成为学生学习物理的难点之一,如何在教学中进行有效突破,以提高教学效率?这是广大物理教师探索的课题之一.本文结合教学实例,从理论教学和习题教学两方面,阐述了比较教学法在帮助学生深化理解理论知识、提高学生解决问题能力等方面起到的积极作用,旨在为解决高中物理教学中的易混淆、不同内容但有着共同内涵的知识点提供一种思路和方法. There are many confusable concepts and models in high school physics study, which become one of the difficult points for students to study physics. How to make effective breakthrough in teaching so as to improve the teaching efficiency? This is one of the topics explored by the majority of physics teachers. Combined with teaching examples, from the theoretical teaching and exercises teaching, elaborates the comparative teaching method to help students deepen the understanding of theoretical knowledge, improve students' ability to solve problems and so plays a positive role, designed to solve high school physics teaching easy to confuse , But different content but has a common point of knowledge to provide a way of thinking and methods.
