Advantages of distance education: independent study at any time and place, not limited by time and place, as long as a computer or mobile phone with internet access can realize the dream of learning.

Disadvantages of distance education: I can't communicate with the teacher immediately, and I can't solve problems in time when I meet them.

Suggestions for improvement: students in distance education should set up virtual classes, arrange special teachers as class teachers, give feedback to students' questions at any time, and play a bridge role between students and lecturers. In addition, check-in should be arranged regularly every week to answer questions, so that students with questions can get together and ask the lecturer.

The above is all personal work experience, I hope it will be useful to you.
