In most classrooms that I've worked in, there are always students who are isolated from their peers for behavioral reasons. In the 1st grade class I subbed in yesterday, there were three students who were seated this way. I actually separated one boy from his row yesterday and he then was able to complete all of his work without interruption. I've seen this done in all elementary grades. Is it a common, accepted practice? Do you think that it is demeaning to the students? It seems to be a necessity in some situations when all else has failed.
