"Micro-class" refers to the whole process of recording teachers' wonderful teaching and learning activities around a certain knowledge point or teaching link with video as the main carrier in the process of classroom education and teaching. Micro-course can be understood as a course with less knowledge points. Compared with offline classes, a class lasts 45 minutes, and the video duration of micro-classes may be 5-25 minutes. Of course, for some live courses, many support review (repeated playback), so the duration will be longer, but mainly short micro-courses, and the knowledge points are fragmented. Online teaching has also broken the offline space and time constraints.
