I think they are both copying off a german model. I don't know if they still do it in Germany or not. But in both Russian and Japanese schools(and i am sure it is the case in Taiwan and Korea as well) students are supposed to do clean up of their classrooms, the adjacent hallways and the school grounds. The duty rotates, but all the kids do it. At the primary and Jr high level they aren't expected to do it that well but it is part of the job of being in school. In Russia the parents are expected to participate on a regular basis as well. The goal here is to learn your place in society, and that jobs get done because people do them It is as much a part of the educational experience as the alphabet and the times table. It is part of becoming civilized. Does anyone think this would be a good idea for US schools?
