First of all, live classroom can make teachers and students realize classroom interaction. Before, many parents were worried that online teaching was not effective because of the lack of real-time interaction. Teachers can't get feedback from students at the first time. If you choose a good tool for interactive live broadcast, you don't have to worry about this problem.
Secondly, professional live classroom can isolate the entertainment atmosphere of ordinary live classroom and restore the seriousness of offline teaching. During this time, some teachers may use ordinary live broadcast to deal with emergencies, but students are often attracted by "likes and gifts" and distracted in class.
To sum up, choosing appropriate and professional tools to build a live classroom can realize online interactive live teaching, and the most important thing is to ensure the teaching effect.
