most grandmothers or grandfathers can teach a pre-k or g1 class. colleges can offer the same inducements for wannabe teachers that are offered to basketball and football and volleyball players. free everything as long as they get decent grades. also, who thought up the four year graduate program? i think a ninety day orientation class then into the classroom for one year as a teacher assistant could be handled by most sincere students. ojt in this kind of work is better than sitting in a class for four years learning theory.
