postgraduate studies

When i ended my studies  I don’t really want to study a postgraduate in pharmacy or chemistry, but I want to study (maybe) another career  which is pedagogy in chemistry, because I want to teach chemistry to the boys and girls that are abandoned by the system obviously the poor people, which studies in publics high schools whit names of Russian submarines and whit teachers that they don’t give a damn about the kids or themselves, so I really want to make the differences there, teach them to fight against the “fate of the poor” and grow like men and women with a good future ahead, so, if I can do it, this will be the thing that I  want to study and why I want to do it

if I can study pedagogy in chemistry I would like to do it in the Chile university, or maybe in the catholic, to see how different is one against the other,  maybe which one is best?. Obviously I will try to study it in Chile, maybe work and study at the same time, also I would study it the evening to study and work or maybe (in fact, I don’t think this exist) part time, but the most important thing is that I would try to study it so fast as I can to validate so much courses as I can.
