Affected by the epidemic, learning turned online. How long is the most reasonable time to study online every day?

In this epidemic, students all over the country can't go back to school according to the normal starting time. However, schools all over the country have also adopted the policy of closing classes and not stopping studying, so that students can take classes online. Many schools arrange a one-day course for students, from 8 am to 4 pm, especially for some senior three students. The course is more tense and the class time is longer. So many people will ask, how long is the most reasonable time to study online every day? Let me give you my opinion.

The biggest difference between online learning and offline learning is that you can't face the teacher, and some schools are not teachers in your own class. Online teachers are not only aimed at a school, but all students in a city or a province! Some cities also have strict requirements for online teaching time, two hours at noon and one and a half hours in the afternoon. If students stay in front of their mobile phones or computers for a long time, it will do great harm to their eyes. So for the sake of students' eyes, I think it's best to study online for 3-4 hours every day, so that their eyes can get a full rest. Let them digest what the teacher says in their spare time, even if they attend classes online, the most important thing is to make every student understand as much as possible.

Now some universities may only need to study for about three hours a day. But high school study is very long. There are also some places where there are restrictions on the time of a class, and there are also some restrictions on the learning time of students. This can also reduce the burden on teachers and give students more time to think. The policy of stopping classes and studying is very good, so that students can know what their tasks are, and don't let their studies go backwards because of the long holidays!

This is my opinion. Of course, there should be more reasonable study time. What do you think is the most reasonable online class time? Come and talk about your opinion in the comments section!
