E-learning 2.0 By Stephen Downes at elearn magazine. Big splash in the blogosphere about this one – ‘me too blogging this’ just for PKM purpose.
In the world of e-learning, the closest thing to a social network is a community of practice, articulated and promoted by people such as Etienne Wenger in the 1990s. According to Wenger, a community of practice is characterized by “a shared domain of interest” where “members interact and learn together” and “develop a shared repertoire of resources.”
For the most part, though, what constituted “community” in online learning were artificial and often contrived “discussions” supported by learning management systems . These communities were typically limited to a given group of learners, such as a university class, had a fixed start and end-point, and while substantially better than nothing, rarely approached Wenger’s theory.
