1, which requires more autonomy for students. This is also one of the points that online education has been questioned by the public. Under online education, students face the computer alone, and it is difficult for teachers at the other end of the network cable to deter students, relying entirely on students' independent learning. Learning is anti-human, so the educational effect of online education is uncertain.

2. Online education lacks necessary emotional communication. Because online education is built online, it is difficult to communicate face to face with teachers and students like offline education. It is difficult for teachers to quickly grasp the students' learning situation and psychological state, and communicate emotionally in words and actions in time according to the students' specific conditions. Students are always faced with the sound from the cold machine, so it is difficult to feel the humanistic care of the teacher, and it is also difficult to adjust the state in time to study.

3. Students' autistic learning. Under the traditional education, most students study in big classrooms, and through cooperation and communication with classmates, they can better master knowledge. Under online education, although some live broadcast modes also support real-time interaction between video and voice, learners still learn on their own computers or mobile phones. Learners are human beings and need real social occasions, teamwork and the ability to discuss with each other. Now online education can't be solved well.
