This year the TED conference awarded their top prize to this talk by
Sugata Mitra entitled "Build a School in the Cloud":

The point of the talk is asking for educational technologists to
design and offer peer-oriented learning systems. But such systems
already exist. The most advanced of which at present is called
PeerWise:
http://peerwise.cs.auckland.ac.nz/
In short, PeerWise is an automated self-study, low-stakes assessment
system where both questions and answers are edited and reviewed by
anyone (with access; in practice this usually means anyone enrolled in
a course or major at an institution) very similarly to textual content
in a wiki. It is already being used successfully at hundreds of higher
education and other institutions. But sadly it's closed source. I
have since 2009 been trying to encourage the Foundation to build an
open source version of such a system.
Is there anyone else interested in this?
