1.通过演示实验可以让学生更加牢固地掌握基础知识。现行的物理教科书中安排了很多演示实验,可见演示实验很重要。通过演示实验可以给学生提供直观形象的感性认识,让学生明白物理概念,懂得物理规律,使学生更加牢固地掌握基础知识。初中生生活阅历少,实践经验缺乏,对抽象的物理概念和深奥的物理规律都望而却步,存在着不同的掌握困难。把相应的演示实验呈现在学生面
1. Through the demonstration experiment allows students to more firmly grasp the basics. The current physics textbook arranged a lot of demo experiments, we can see the demonstration experiment is very important. By demonstrating experiments, students can be provided with an intuitive perception of perceptual image so that students can understand the concepts of physics and understand the laws of physics so as to enable students to master the basic knowledge more firmly. Junior high school students experience less, lack of practical experience, abstract physical concepts and esoteric laws of physics are prohibitive, there are different grasp difficulties. The corresponding demonstration experiment presented in the student face
