在物理课的教学中,实验是一种有力的手段,但是在教学中受到诸多条件限制,所要说明的问题无法在课堂上实验,此时可以采用下面一些常见的方法辅助解决:纯语言描述、图片辅助说明、动漫演示以及视频影像等。笔者在教学实践中体会到:视频影像由于直观性强,真实度高,比其他几种方法更便于学生理解。即使有一些可以用实验来说明的问题,如果有恰当的视频影像来辅助,对于学生的理解也不无裨益。下文以课堂教学中的实际案例来说明。 Experiment is a powerful tool in the teaching of physics, but it is limited in teaching. The problems to be explained can not be tested in the classroom. Here are some common ways to help solve: pure language description, Picture support instructions, anime presentations and video images. The author realizes in the teaching practice: As the video image has strong visualization and high realism, it is easier for students to understand than the other methods. Even if there are some problems that can be experimentally illustrated, the understanding of the students is not without benefit if there is an appropriate video image to assist them. The following is a case study of the actual case to illustrate.
