From Edudemic – There is ample research to show that a community based education model can greatly enhance the learning capabilities of its members. Moreover, learning is inherently a communal activity, which is perfectly exemplified by the classroom setup, where a group of students interact amongst themselves and with the faculty. Transpose this behavior to the world of internet and we have what we call online learning communities.
