English as the official language on all school premises

Having travelled throughout the continent and spent time in other countries on the continent, I've always been struck by how a majority of the population in these countries speak English very comfortably. Apparently what schools in some of these countrues do is they force school kids from a certain age to only speak English from the moment they enter school premises until they leave for home. This way kids are put in a situation where they are pressed to train theselves in the English langauge such that by the time they reach high school they are already fluent, meaning they can read books, journals etc comfortably. Interestingly, this appoach has not led to home langauges declining in usage, as the kids still go back home and converse in they home language, in this way English exists side-by-side with other languages. The point however is that ensuring that kids get comfotable with the English language earlier on in life must surely increas their chances of having a better grasp of the world around them. Imagine if our education system in South Africa adopted this approach, where English was the "official" langauge across all school premises through our country across all townships and suburbs alike. I'll be the first one to admit that this simple suggestion will not solve all our education problems it will go a long way in enhacing the future of all school-going kids in South Africa.
