"The Personal Learning Environment concept is relatively new and is often used interchangeably with Personal Learning Network. The earliest reference is attributed to George Siemens in his 2004 paper, Connectivism: A Learning Theory for the Digital Age. Downes and Attwell have also popularised the concept with Downes describing the PLE as "a tool that allows for a learner (or anyone) to engage in a distributed environment consisting of a network of people, services and resources" (2006, p23).
Semantically, a personal learning environment and a personal learning network differ, with a network referring to connections and the interaction between them, and an environment referring to a broader definition that includes more passive tools and settings. The network and its broader socially constructed environment are interdependent, constantly shaping each other and unable to be separated."
"There has been lots of discussion this week about whether Personal Learning Environment (PLE) and/or Personal Learning Network (PLN) are the right terms to describe what this is all about and some recognition that this a semantics issue. According to Rita Kop PLE is a UK term and PLN an American term. Dave Cormier questions whether the term personal should be used at all. Stephen Downes points out that personal is an OK term if you think about [Personal Learning] Network as opposed to [Personal] Learning Network - and similarly for PLE. I like that - but for me, the words are not as important as the process - although I can see that the process needs nominalising for ease of reference. If I am going to think about introducing the idea of PLEs/PLNs to my colleagues or students then I will be talking about the process and the implications of this process for learning rather than what we should call it, i.e. why it might be preferable for students to learn in environments/spaces of their own choice rather than be confined to an institutions VLE/LMS."
