"Sitting together" punishment is very common on campus. For example, some media have revealed that some teachers stipulate that a student in the class has not finished his homework and the whole class must copy the text; One person is not disciplined, the whole class stays in school to reflect and so on. Perhaps some people will defend the punishment of "sitting together" from the perspective of "one glory and one loss", thinking that it is to cultivate students' sense of team consciousness and collective honor, but it is actually a misunderstanding of the collective concept. Students' study and life are mainly independent individual behaviors. Although students help each other, all the students in the school are not really a team with clear division of labor and cooperation. It is unreasonable to punish others with one person's mistake on campus, which is euphemistically called "collective consciousness and team consciousness"
