The reason why the school requires this is because the school requires students to observe ten minutes of silence during the break, and because the school requires students not to play during the break. In addition to going to the toilet and drinking water, students basically stay in the classroom, do not leave the classroom, and do not participate in any extracurricular activities. For the sake of students' safety, the school does not encourage students to play outside the classroom during recess, which also leads to students staying in class for ten minutes during recess, sometimes even not going out for a walk, and there is no conversation between classmates. We know that in these ten minutes, there is little time left for students to play, and often when the teacher in the next class comes in, the students are already seated.
Education in China is another reason for this phenomenon, because it is a traditional education model in China. In the previous education model, we did not encourage children to go downstairs to play when they went out. The first reason is to prevent safety accidents. The second reason is that students are under great pressure and have a sense of competition. During the break, they often use these ten minutes to make up some knowledge that they have not fully mastered in class. For children, this ten-minute break may not be for rest, but for continuing to learn. In the past education, we encouraged children to study hard instead of asking them to have a strong body. This model has continued until now, and many people have not changed this way of thinking.
Regarding some problems in this regard, schools need to make changes to encourage children to go out of the classroom and do activities during recess to relax their nervousness and relieve fatigue. Ten minutes of relaxation can make children better devoted to the next class.
