Under the influence of this year's epidemic, all walks of life have been greatly impacted, whether it is diplomacy, tourism, traditional manufacturing, commerce, handicrafts, education, architecture, medicine and so on. Even the long-lasting education industry has been greatly affected, in the first half of the year. Students of all ages stopped going to school, kindergartens stopped directly, and online classes stopped. Pupils and junior high school students postpone the start of school and take online classes at home. Even the high school students who are facing the most severe situation of further education have postponed the start date and have classes online at home. Many college entrance examination students can only review at home, not to mention that the college entrance examination has been postponed for a month. The most relaxed college students don't go to school directly and spend the whole semester at home.

However, can this really make students learn knowledge well? Can these courses really be taught online?

This is unrealistic. Many students study at home to cope with chores. They are not serious and their attention is seriously distracted. Sign in, hang up and leave. Not to mention the phenomenon of being late and leaving early, the teacher has no idea at all. Let many students who don't study hard take advantage of it. There are also many school exams conducted online, which provides many students with opportunities to cheat. Therefore, online classes are really not conducive to the study of most students, because many students have poor self-control and self-discipline. The most important thing is that some courses are really difficult to teach online, such as physical chemistry experiment, physical education class and measurement. These subjects all need practical operation. For example, we need a physics experiment class this semester, which was originally operated in the laboratory, but because of the epidemic, we can only do it on the computer, do the experiment with the simulation experiment program, watch the teacher demonstrate, and finally do it ourselves. But this is really unrealistic. After doing it, it feels the same as not doing it, and there is not much feeling. There are also home experimental classes, looking for experimental materials, screw micrometer, laser pen and so on. It is really unrealistic.

So, let's go back to school as soon as possible, so that we can learn better.
