Because of some reasons this year, and the crowd of college students is very dense, I think we should arrange seats for classes. You can't sit anywhere and sit together in class as before. I think we should first set a reasonable seat for college students, like high school and junior high school. For example, in the first row of a classroom, there used to be 12 people, so now only four people can sit in each row, and then there are three seats in the beauty pavilion in the middle. In this case, although some students may need to have classes in the last row of the classroom, we can keep the distance between students well so that. There is also, for example, there are a large number of students in one of our majors, so we have to get off work at this time, and we can't attend classes according to the previous number, because if we attend classes before. The seats in the classroom should be just full, and students can't have reasonable composition arrangements. At this time, it will be divided into two or three classes, and then classes will be held separately, but if it is divided like this, the teacher will definitely be tired. After all, teachers will have more classes. But this year, because of this epidemic, the seating arrangement is actually difficult to manage. Another way is to put a partition between students' positions, so that although students sit next to each other, their faces can't communicate with each other, that is, if they wear masks. If they don't communicate with each other, they are quite isolated, so I always have two pieces here. One is to let students divide several seats and one student arrange them. Then there is another plan, that is, putting partitions between seats can also help students avoid direct contact. What methods do you think are good?
