Indeed, the classroom has become a live broadcast room, and most institutions and teachers are not prepared, especially some people have camera phobia. Usually I can talk freely with real students online, but I don't know how to teach through the screen. Here are some online live teaching skills for teachers:

Choose a simple live broadcast platform, preferably fully functional and easy to use. It is not recommended to choose non-professional live broadcast software, and carry out platform testing and simulation before the official live broadcast;

It is best to set up a teaching assistant. This function is not available on all platforms, but it can ensure that teachers have assistants to help maintain class order and avoid being in a hurry.

In the comment part, make a description of the classroom rules, and make clear which rules students should abide by in the classroom;

Teaching interaction should be done during teaching, preferably once every ten minutes to avoid students' distraction;

Don't rely on the courseware to read the lecture notes. The key points are prominent and the tone is ups and downs. Summarize them every few minutes.

I hope all teachers can adapt to this online teaching and master more teaching skills. In the future, we can also consider using live broadcast for teaching assistance.
