I am not sure about that since the most searched subjects are celebrity ,beauty and fashion based subjects and next to that would be health issues.Educational topics other than the Information technology may not be high on the list.However, when you want to write an article based on Educational topics you have to write with the idea of sharing rather than expecting high traffic...If the article is good and informative , it will bring in traffic anyway !
Pay no mind to those who talk behind your back, it simply means that you are two steps ahead !!!
