distributed learning networks (DLN’s), or personal or professional learning networks (PLNs), or personal learning environments (PLE’s)–all provide direct (and indirect) contact with many people in one’s network, each possessing a reservoir of knowledge which contributes to the entire pool of knowledge residing in the network. This can be accessed through listservs or sometimes almost instantaneously through Twitter or RSS feeds, or Skype, or instant messaging. Therefore the knowledge possessed by any individual, or node in the network, is the sum total of all aggregated knowledge within that network. It is to this that we ascribe the incredible power inherent in distributed learning networks which often comprise to some extent communities of practice.
