I can see why NT Minister for Education Marion Scrymgour's announcement that only one hour of classroom time per day may be conducted in children's Aboriginal language might seem like a good idea to many people who've never lived and taught in an Aboriginal language speaking community.
This could be their logic: Aboriginal employment is very low because their education level is very low. The key to educational success and participation in the mainstream is English proficiency. They are not learning English while they are speaking their own language. Therefore we will force them to use English in school for four and a half hours a day.
