物理实验课前预习微课的制作

Producing micro-class of physics experiment preview

将仪器的结构和操作过程以及实验原理的相关应用等制作为微课,使实验课前预习的手段更为丰富:一方面使实验前的预习由呆板的文字和平面图变成了动态的画面,让学生在较短的时间内充分理解实验内容;另一方面,也能使学生了解实验原理在实际中的应用,开阔学生的眼界和思路.以如何调整分光计为例,介绍了微课选题原则、制作侧重点、拍摄方法以及后期处理技巧.

In order to make the preview means richer,the micro-classes were produced with instrument structure,operating process and related application of experimental principle.On the one hand,it turned the plain words and planar graph into dynamic images,the students could fully understand the experiment content in a short time.And on the other hand,it also enabled students to understand the application of principles in practice and broaden students' vision and thinking.Taking the spectrometer experiment as an example,the principle of micro-class selection,production emphasis,shooting method and post-processing technique were introduced.
