Network video course refers to the so-called teaching method that students watch related network courses through the network platform. This teaching method mainly relies on multimedia technology, and transmits teaching materials such as teachers' classroom explanations to students' electronic devices through live video, recording and broadcasting, which makes up for the deficiency of traditional teaching mode to some extent and allows students to learn and master knowledge independently.

Online video courses are increasingly favored by professionals and students at school. The main reason is that it can save time and transportation costs. Students can choose the speed of video playback and fast-forward or repeat key content according to their own learning progress, which solves the problems of too fast speech speed and unclear key content in some traditional education models.

Online video courses can not only better follow up the latest educational demands in the world, but also promote subject integration and resource sharing to the greatest extent, promote online and offline interactive communication, and improve students' learning efficiency and knowledge-mastering ability. At the same time, in the video course, the interaction and communication between teachers and students can also be effectively realized through online chat rooms, forums or comments.
