1. Resource utilization: All kinds of educational resources have crossed the limitation of spatial distance through the network, making school education an open education that can radiate to a wider area outside the campus. Schools can give full play to the advantages of disciplines and educational resources, and spread the best teachers and teaching achievements to all directions through the network.

2. Learning behavior: network technology is applied to distance education, and its distinctive feature is that anyone can learn any course at any time and any place, starting from any chapter. The convenient and flexible "five arbitrariness" in online education directly reflects the characteristics of active learning in the learning mode, which fully meets the needs of modern education and lifelong education.

3. Learning form: Teachers and students communicate in all directions through the network, which narrows the psychological distance between teachers and students and increases the opportunities and scope of communication between teachers and students.

The disadvantages of online education include:

1. Weakening of supervision: It is common for students not to attend classes seriously, skip classes and default on homework.

2. Group discussion is difficult: the frequency of interaction between students is reduced.

The exam is very difficult.
