I don't know if you have noticed that teachers in universities always talk about ppt directly, and there is nothing very profound, so endorsement during exam week is the most effective way. Since then, science has gradually become a liberal art. Then why are we taking online classes? I think there are three reasons:
1, usually when we are in class, even if you don't listen, at least you will have a little impression. At school, many students started playing with their heads down in the teacher's "invisible place", but now they stay at home and have classes online. Many people are even more unscrupulous, and people who play mobile phones behind the screen abound. Many people will wonder, since they all play mobile phones in class and don't attend classes anyway, what's the point? Please think it over. We always have some scruples in class. Sometimes you will feel that you didn't listen to this class after class, but you will always remember something.
Online courses provide great convenience for many students who are usually afraid of asking questions. Many introverts are afraid to ask questions to their teachers in class, but they are not afraid of teachers in real life and can let go of themselves.
3. Online courses make the path of knowledge dissemination longer. In the past, when we were attending classes at school, we had to sign in in advance. Sometimes, because of the time, we didn't have time to have dinner. Now it's different. We don't have to rush to the lecture site. We can listen to teachers from universities online anytime, anywhere.
So don't say that it is meaningless for college students to take online classes ~ Although online classes are not as good as traditional classes, they are also beneficial.
