Can online classes completely replace classroom instruction? Why?

Certainly not. For students taking online classes, it's all about self-control, and without the supervision of a teacher and the motivation of their peers, the effect of learning will be greatly diminished. Online class can only be used as a supplementary learning mode, the previous online class is not so prevalent, just because of the two years of the epidemic environment, no choice but to do.

Classroom teaching as our country has been the traditional way of education, is necessarily irreplaceable. If the teacher and the students do not have a face-to-face communication between the interest in learning is also greatly halved, and the students in the school to learn will certainly be more, do not understand can communicate directly with classmates, including in the school, they can learn to socialize with others, out of the school, can be better adapted to the social environment. If it has always been at home in the online class, not inevitably some boring, all day long are just to a computer, cell phone, no more teachers face-to-face supervision, in front of the computer to do what other distractions, there is no one to remind, can not learn something is entirely dependent on their own self-control.

The overall disadvantages of online classes outweigh the advantages, or the state will not require schools to start teaching again when the school year begins after the end of the epidemic. The effect of online classes on individuals is a matter of opinion, and some hard-working students may not be affected by the environment and be able to learn just as well, but for students with poor grades and struggling to learn in the classroom, it's an excuse not to study hard.

And for modern teenagers, with the popularity of cell phones and computers, myopia is also climbing year by year, and more and more students are wearing myopic glasses. If you still have to use online classes all the time to learn, it is also not a small damage to the eyes. Learning itself, the atmosphere is very important, their own learning at home, for many students, far less than the effect of classroom learning, and students who do not go out for a long time, do not communicate with their peers, the ability to socialize with others will decline, will become withdrawn, do not like to talk, more or less on the character of the impact. Therefore, I think online classes can not completely replace classroom teaching.
