由于数码相机、电脑的普及和相应性能的优化,为课堂演示实验教学提供了不同的呈现方式,对于有些动态物理过程,由于过程发生时间短、空间小,直接通过观察去研究较为困难,用先期制作好的图景材料缺少真实感,在课堂上对发生的物理过程直接记录呈现和再现,将收到较好的教学效果.现在很多学生都能熟练地应用数码相机和电脑,他们完全有能力参
Due to the popularization of digital cameras and computers and the optimization of corresponding performances, different presentation methods are provided for classroom demonstration experiment teaching. For some dynamic physical processes, due to the short process time and small space, it is more difficult to directly study through observation and use advanced methods. The lack of a sense of reality in the production of good picture materials, the direct recording and reproduction of the physical processes occurring in the classroom, will receive a better teaching effect. Now many students can skillfully use digital cameras and computers, they are fully capable of participating in
