物理是一门以观察和实验为基础的学科。物理概念的建立、规律的探索与验证都离不开实验,实验教学是中学物理教学的重要组成部分。实验教学既是物理知识教学的基础,也是实施素质教育的一种主要渠道和有效手段。实验教学的成败直接影响物理教学的质量。教师在教学过程中正确地进行演示实验或指导学生实验,对学生理解掌握物理知识、运用知识起着积极的作用,同时还能激发学生的求知欲望,培 Physics is a discipline based on observation and experimentation. The establishment of the concept of physics, the exploration of law and verification are inseparable from the experiment, experimental teaching is an important part of high school physics teaching. Experimental teaching is not only the basis of physical knowledge teaching, but also a main channel and effective means of implementing quality education. The success or failure of experimental teaching directly affects the quality of physics teaching. Teachers in the teaching process to correctly demonstrate the experiment or guide students in the experiment, the students understand the grasp of physical knowledge, use of knowledge plays a positive role, but also stimulate students’ desire for knowledge, training
