1, using Tencent classroom for online teaching requires debugging a few minutes in advance. After debugging, playing PPT pictures and explaining sounds can be synchronized, with almost no lag.

2. The operation of the whole interface is relatively simple, and you can attend classes quickly without auditing. After sharing the QR code, students can quickly enter the online class.

3. There are some simple interactive settings, such as raising your hand and signing the answer sheet.

4. It's easy to join the class. After joining for the first time, it will be memorized automatically, and you can log in directly after opening the client.

5. There is also the function of sharing audio, which is better.

Disadvantages:

1. I feel that the effect is different in different time periods. For example, the picture and sound synchronization in the afternoon is not very good, but it is smoother in the morning and evening.

2. Occasionally, there will be a jam phenomenon, which is mainly affected by the network speed at the teaching end and the network stability at the receiving end.

3. Lack of communication and interaction.
