在物理教学中,我们常常以演示实验为基础,让学生获得实验事实,并在这个基础上,经过由此及彼、由表及里的分析、对比、归纳、总结,达到认识物理现象,掌握物理规律的目的。在课堂上把演示实验做出来,那只是最基本的要求,我们还应该在设计中追求演示实验中的美。一、细节设计美课堂演示实验中的细节设计,能在学生大脑皮层产生强刺激,取得“一石三鸟”的 In physics teaching, we often use the demonstration experiment as a basis to allow students to obtain experimental facts. Based on this analysis, comparisons, conclusions, and conclusions, the physical phenomena are understood and mastered. The purpose of physical laws. Demonstrating the experiment in the classroom, it is only the most basic requirement. We should also pursue the beauty in the demonstration in the design. First, the details of the design of the US classroom demonstration experiments in the details of the design, can produce strong stimulation in the students’ cerebral cortex, to obtain “one stone three birds”
