Han has a Ph.D. from Harvard and she has, no kidding, an impressive bucket list. And I can follow the reasoning behind her data crunching, but not the crunching itself. And if her findings seem vaguely familiar, it's because they have been covered elsewhere (check out this interview with Han from Edushyster). But there are some pieces of research that are worth re-blogging about. You say "redundant;" I say "amplifying the message."

So here are the conclusions Han reached with her data crunching.
