Advantages: It solves the problem that classes cannot be held together in special periods. It enables teachers to further innovate teaching methods. To some extent, it saves the time of teachers and students.

Disadvantages: insufficient interaction between teachers and students. Students' study can not be effectively supervised.

Improve the deficiency: make full use of the function of the network platform to improve the interactivity of teaching. Take offline as the main mode, supplemented by online mode, and learn from the strengths of many families.

Online teaching improves efficiency;

1. First, we should strengthen students' ideological education. Students study at home, school ideological education can't keep up with the rhythm, and the supervision of students is almost handed over to parents. Due to the lack of family education at this stage, students are seriously rebellious and have serious resistance to their parents' education, so ideological education in classes is particularly important. The school can organize students by the class teacher to summarize this week's online learning, and at the same time strengthen students' moral education in a timely manner in combination with disciplines and humanities themes to implement the goal of educating people with moral education.

2. Teachers should rationally integrate resources and do a good job in teaching design. In the process of online teaching, we can find that there are many teaching resources on the Internet. Teachers should carefully prepare lessons according to the classroom situation and learning situation, and effectively screen and integrate teaching resources such as micro-courses, exercises, knowledge expansion and after-class training.
