I could see (potentially) there being a dramatic difference between a teacher saying "take this computer home and play with it" and finding a box that comes with no external social pressure from authority figures. Not sure if the latter would be replicable though (some teachers have told me the biggest problem with educational research is that all the most promising experimental schools turn out to only really work in their original context).
Just read this article, which describes a splashy, interesting narrative which jives nicely with my worldview. Which makes me suspicious.

So this sounds really inspiring and stuff, even subtracting some obviously sensational stuff (I assume "hacked Android" means "opened up the preferences dialog and flicked a switch"). I've poked around a bit and found similarly fluffy pop-philanthropy articles. Anyone know if there's more reliable information about this out there?
