The network breaks through the limitation of time and space, gives learners more flexible learning methods, and opens up another way for those who cannot enter the palace of higher education to acquire knowledge and academic qualifications.

Most teachers of online teaching are conscientious, and the research on online learning strategies, tools and resources is being carried out in depth, striving to make online teaching not inferior to traditional classroom face-to-face teaching, so that the network can also shoulder the responsibility of "preaching, teaching and solving doubts". However, it must be admitted that, as a new thing in China's educational reform and development, the success of online teaching ultimately depends on its teaching quality and level. Therefore, from the development of network teaching, it is urgent to establish a set of quality assurance system from teaching to management, monitoring and evaluation.
