Sorry just saw your transfer note. Might want to use more tags to increase visibility, such as education. Also find some curators who cover your type of subject matter. Steem peaks seems to be more geared toward the educational area, but i haven't used it myself yet.
If you go to the menu on steemit's top right, check out Explore. There you can see how tags are performing in regards to post numbers, vs payout.
