Ok, well Im sorry to say the original post does not really make much sense when translated to English
It is clearly about providing chess as an option in schools. What is the rest of it about? Is it that research shows the grades were higher for the students who chose chess than students taking other subjects?
Maybe it makes more sense in Persian. It is a shame because it might be interesting, but it just not clear from the post what the research shows.
