Brian Epstein, Synthese, 2017/04/20

By Stephen Downes - Stephen's Web. Peers, more than teachers, motivate us to learn
Andy Henion-Michigan State, Futurity, 2017/03/21

Interesting summary of a publication (I can read it here but it might be blocked where you are) suggesting, as the title says, that peers motivate us more than teachers. More...
