物理学是一门以观察和实验为基础的科学。随着新课程改革的深入,物理课本上的插图是越来越多了,其新颖、直观,对提高学生们的思维能力是非常有帮助的。同时,它也要求教师们要通过大量精细的演示实验来对物理内容加以验证和探究。而且课堂演示实验是中学物理实验教学的重要组成部分,它不仅能帮助学生建立物理概念和规律、理解和掌握物理知识,还能培养学生的观察能力、思维能力、探索精神以及良好的学习习惯,也是变应试教育为素质教育,提高人才科学素质的重要手段之一。
Physics is an observation and experiment based science. With the deepening of the new curriculum reform, illustrations of physics textbooks are more and more. Their novelness and intuition are very helpful to improve students’ thinking ability. At the same time, it also requires teachers to validate and explore the physical content through a large number of elaborate demonstration experiments. And classroom demonstration experiment is an important part of physics experiment teaching in middle school. It can not only help students to establish physical concepts and laws, understand and master physical knowledge, but also develop students’ observation ability, thinking ability, exploration spirit and good study habits, It is also one of the most important means to improve the scientific quality of talented people by changing the education on probation into quality education.
