"Bloom's 2 sigma problem refers to the educational phenomenon that the average student tutored one-to-one using mastery learning techniques performed two standard deviations better than students educated in a classroom environment."
Um, what?! Why the hell am I not doing this for myself?
Every single person I know who graduated college before 20 had a significant amount of their primary and/or secondary education somewhere along those lines. Sure, they were all also of above average intelligence, but most of them by not more than about 1 standard deviation.
The schools around here are moving in a diametrically opposed direction to mastery learning by making sure every student is in the same class regardless of past performance (no honors classes, no remedial classes, no testing into advanced math &c.). The result was entirely predictable to pretty much everybody except the administrators who came up with this policy.
