The teacher is only separated from you by a screen in class, giving feedback in real time. Just like normal class, he doesn't know how to ask questions in time. Similar to the usual class, there are live classes, homework, playback, question bank, question and answer group and so on.
Advantages of live broadcast:
1, during the school and internship, you can score points by live webcast or recording.
2, you can play back, you can look back if you don't understand!
3. Like the scene in the classroom, it has a strong sense of picture.
4. Ask questions in class. If you don't understand, point it out and the teacher will answer them immediately.
The teacher's class is lively and interesting, and will not be influenced by the students around him.
6, not afraid of hearing or seeing in class!
