Which environment is more conducive to education? Single gender or Co-education and why?

If you wish to incorporate "basic" life skills/experiences into education, then I would suggest co-ed, Certainly a single gender education system will negate some of the obvious distractions that might be encountered within a co-ed system. But would this in turn have a "delaying" effect on a student's social development? In my opinion both systems have their merits and faults and I, for one. wouldn't be able to separate them!

Co education for the simple fact that it increases competitiveness in both genders in the classroom and school. I am not fond of single gender classrooms as it takes away the edge, the competing mentality that is needed for further development and the future, and it creates this wall between working with genders as we get older.

Dear Anayat Bukhari sahib , the co-education system  create a competion environment in class, if you can keep all safeguade measurement boys and femals.
