Her parents have every right to make this request, for whatever strange reason they may have. However the school should not hender others students lives to make accomodations for it. The only thing that the school should do is make sure she always has a female teacher when possible and during class projects make more of an effort to make sure that at least one of her partners is a girl. Other than that she should not get special seating or be placed in special groups. None of the boys in the class should have been moved because that hampers their learning envirnoment. If the girl happens to sit next to a boy then she just shouldn't talk to him. And no one should force her to do so. However I think this might cause problems for the girl if she ever needed help or something and only men were around and it might cause her to have some social problems when she is old enough to talk to boys, but unfortunatly thats going to be her problem not the school's.
