There is a great difference between online teaching and offline teaching.

1. Education has different forms. Network teaching is mainly based on network, and there are two forms: live broadcast and recorded broadcast.

2. There are different requirements for students. Offline teaching is a dialogue between students and teachers, which can better supervise students' serious progress in their studies.

3. The degree of convenience is different. Online teaching can better enter teaching if there is a network, while offline teaching is to directly understand students.

4. The learning effect is different. Network teaching means that teachers can't correctly see the shortcomings of students in their studies. Offline teaching allows teachers to communicate with their parents.
