物理实验是物理教学中的重要内容,也是物理研究的一个重要方法和手段。在物理课堂教学中,演示实验是加深学生对概念和规律理解的重要一环,是学生认识物理规律的感性基础,是物理教学中将理论与实际相结合的重要方法,是提高学生学习兴趣、启发学生积极思维的重要手段,是认识事物规律的起点,也是物理实验教学中的一个重要组成部分。现在使用的人教版初中物理教材中实验较多,有些实验看起来非常简单、然而要真正把它做好却不容易、有的演 Physics experiment is an important content in physics teaching, and also an important method and means of physics research. In physics classroom teaching, demonstration experiment is an important part of deepening students’ comprehension of concepts and laws, is the perceptual foundation of students’ understanding of laws of physics, and an important method of combining theory with practice in physics teaching. It is an important method to improve students’ interest in learning, An important means to inspire students’ positive thinking is to recognize the starting point of the law of things and also an important part of physics experiment teaching. There are more experiments in the textbook for junior high school of the PEP currently being used, and some of the experiments may seem very simple. However, it is not easy to actually do it well. Some of them perform
