Some students lack motivation, consciousness, autonomous learning ability and participation, and can't keep up with the teacher's ideas. The solution is to further strengthen the construction of hardware facilities for network teaching and improve the function of the platform.

2. Teachers don't know enough about the function of the platform, and their online teaching skills are not skilled. Efficiency, methods, interests and attractiveness need to be cultivated and improved. We can strengthen the discussion and training of teachers' online teaching skills or methods, optimize teaching methods, adopt heuristic teaching, pay attention to class pauses, leave gaps, give students time to think, digest and remember, and let students participate in the learning process.

3. Classroom supervision is difficult to fully implement. Teachers are not around, parents have to go to work, and no one is in charge, mainly relying on students' consciousness. Strengthening the method education of students' online learning, such as advocating the method of "preview first and then listen to lectures", can effectively improve the efficiency of listening to lectures.

4. Network congestion occurs from time to time, which affects efficiency. Advocate some families to pay attention to education investment and strengthen the construction of digital conditions such as networks and computers. It is more reassuring to have parents watching.

Advantages of online teaching:

1, which breaks the venue rent limit and student flow limit of offline teaching and makes full use of the advantages of multimedia.

2. Network teaching has broken the limitation of time and space.

3. Online teaching can make more thoughts collide and improve the metabolism of knowledge.
