实验在物理学科的研究和教学中都具有非常重要的作用,特别是在初中阶段,很多物理规律在进行展示时,都可以从一般的物理现象入手,让学生得到视觉、听觉等方面的直观感悟,继而带动其做出深入思考.由此,便涉及到物理实验的简化、巧妙和贴近生活等原则,以保证课堂教学效果的优化.现以光学实验在课堂上的呈现为例,说明这几个原则的实现过程. Experiments in physics research and teaching have a very important role, especially in the junior high school stage, a lot of physical laws in the show, you can start from the general physical phenomena, so that students get visual, auditory and other visual perception , And then led them to make in-depth thinking.Therefore, it involves the physical experiment simplified, ingenious and close to life and other principles, in order to ensure the optimization of classroom teaching effect.Considering the optical experiments in the classroom as an example to illustrate these A principle of the realization process.
