Structure on English a and Arabic language teaching in private and government schools in UAE

I want the paper to describe the English and Arabic curriculum in both government and private schools in UAE. In addition in which language subjects are taught in government schools. In the early 1990 English was taught as a language only, however in today\’s curriculum we see it in other subjects. What are the social reasons behind that change and policies?

For private schools. What is the difference between the Ministry of Education curriculum and open British / private schools. I want to know if there is any policies that demand compulsive Arabic learning in private schools.
