Advantages and disadvantages of online classroom

The advantages and disadvantages of online courses are as follows:

1, Advantages: Online teaching has broken through geographical restrictions. Teachers and students can carry out teaching activities through a computer and a mobile phone, which solves the problem of being unable to travel and gather because of epidemic prevention and control, and teachers and students can complete teaching tasks at home.

2. Advantages: It enriches students' learning methods. Many platforms are broadcast live and recorded, and all have the function of course playback. If students can't participate in the study during the live broadcast time, they can learn independently by playing back the video of the class, which makes the ways for students to learn knowledge more extensive, especially for some students who can be strict and self-disciplined, and the effect of online independent learning will be better.

3. Disadvantages: It has a great influence on students' eyesight. The application of computers, mobile phones and other devices in online teaching poses a threat to students' eyesight health. It will have a negative impact on vision and even health.

4. Disadvantages: network congestion. In a short period of time, a large number of users are concentrated on the line, and various educational apps occupy the memory of the mobile phone. Many smartphones with insufficient performance will switch off the line in time. Especially for teachers, if the network is unstable, disconnected, or the teacher misoperates, resulting in no sound, the whole classroom will be affected.

5. Disadvantages: The classroom atmosphere is light. Without the environment of collective learning, many methods of mutual promotion are not very effective. I didn't see my neighbors study hard, have no role models and can't discuss with each other. Many methods can only be realized by yourself.
