观察和实验是物理知识学习和认知的基本方法,对于一些物理概念和原理,在很多时候要让学生在物理实验中亲自参与,通过自己动手并观察实验结果来获取物理知识。《物理课程教学新标准》中也提出:高中物理课程的改革,实验教学的加入参与是需要教师群体需要加以重视的课改重点。同时,实验教学 Observation and experimentation are the basic methods of learning and cognition of physical knowledge. For a number of physical concepts and principles, in many cases, students are required to personally participate in physical experiments and acquire physical knowledge through hands-on observation and observation of experimental results. The New Standard of Physics Curriculum Teaching also proposed that the reform of high school physics curriculum and the participation of experimental teaching are the key points of curricular reform that teachers need to pay attention to. At the same time, experimental teaching
