中学物理是以实验为基础,通过演示实验和学生实验,使学生能正确理解物理概念,搞清物理规律,从而巩固所学的物理基础知识.实验在中学物理教学中是突破教学难点的一个重要方法.那么,如何以物说理?如何从实验入手来突破难点呢?就此问题,谈谈我们是怎样利用自制教具演示实验,对浮力产生原因这一问题进行实验教学,帮助学生攻破难
The physics of middle school is based on experiment, through demonstration experiment and student experiment, make students can correctly understand the physical concept and understand the laws of physics, so as to consolidate the learned basic knowledge of physics.Experiment is an important breakthrough in the teaching of physics in middle school How to use material reason? How to start from the experiment to break through the difficulties? On this issue, talk about how we use self-made teaching aids to demonstrate the experiment, buoyancy causes of the problem of experimental teaching to help students break through the difficulties
