MOOCs and all that
Online courses open to all seemed to be the flavour of 2012. Although during the last year they have popularly been referred to as MOOCs (Massively open online courses) some are closer to open educational resources or self study resources. The original MOOCs follow a Connectivist philosophy, while the 2012 ones are really more traditional online courses based on open courseware which relies on short videos (see, e.g., those offered by Coursera and edX and the videos from the Khan Academy).
