I am looking forward to have the normal classes in school and I hope Covid-19 can be beaten soon. Because I think there are many disadvantages in online classes.

First, in online teaching, teachers' teaching concepts and habits need to be adapted for a long time. This process is relatively long. In this process, there will be many problems in order and rules, and students will also be confused about learning.

Second, to carry out online teaching, both teachers and students must have a certain knowledge of modern information technology. Some older teachers will delay class time or even a few hours because they do not know how to use electronic products. In this way, the quality of teaching is not as good as before, which will also affect students' learning progress and teachers' teaching plans, and even lead to parents' dissatisfaction.

What’s worse, it is difficult to carry out online teaching in management. The amount of information on the Internet is like a vast ocean. There are scientific and non-scientific information, and some violent and pornographic information are not uncommon. Therefore, the management of online teaching is still a new topic. At present, unless students' electronic products are compulsorily controlled, the school cannot confirm that students are listening attentively. Many students will become addicted to the Internet or some bad things because no one supervises him, and go astray.

  Hope we can go back to school soon.
