MIT's OpenCourseWare initiative was (and probably still is) the highest-profile "open and online" initiative in higher education. According to this article, they're rethinking their approach to help the self-directed learners who have emerged as their biggest users. I'm really excited by this, and by P2PU's peer-to-peer model, and all the others that are emerging (including the hybrid models we're trying out). I also think that asking "which model will win?" misses the point: each one is a best fit for a different combination of educator, content, and learner.
