演示实验既是物理教学活动的重要内容,又是教师开展物理教学活动的重要工具。与语言讲解相比,通过实验手段呈现出来的物理概念、规律等往往更加直观生动,更有利于学生的理解和掌握,可以说,演示实验是提高物理教学质量的重要手段。因此,作为教师,一定要重视物理实验教学的有效开展。在本文中,笔者就结合自己在物理演示实验中的一些体会,简单总结了几点演示实验教学中需要注意的问题,希望能够为演示实验的有效开展提供一些参考。
Demonstration experiment is not only an important part of physics teaching activities, but also an important tool for teachers to carry out physics teaching activities. Compared with the language explanation, the physical concepts and laws presented through experimental methods tend to be more intuitive and vivid, which is more conducive to students’ understanding and mastery. It can be said that demonstration experiments are an important means to improve the quality of physics teaching. Therefore, as a teacher, we must pay attention to the effective development of physics experiment teaching. In this article, the author combines some of his own experience in the physical demonstration experiment, simply summarizes the need to pay attention to a few points in the demonstration of experimental teaching problems, hoping to provide some reference for the effective demonstration experiment.
