I was writing a comment on an interesting blog post by Cecilia Lemos about what having a PLN has done for her, when I realised that this comment deserved to be expanded a blog post of its own, so here it is!
For some time now, I've been concerned about how some people are using this term, which stands for 'Personal Learning Network' and which developed out of the concept of PLE (Personal Learning Environment).
The term PLN is bandied about so much these days it's starting to lose its meaning. Another thing I hear a lot now is people talking about 'the PLN' , which is fine when people are referring to 'their' PLN, but not if they have a big social club in mind that people are either part of or not. This is not a PLN. A PLN is something people have to build and which takes time to nurture and develop. It is also and involves active participation and hard work. It's not just about pressing a button and joining a Ning.
Where did the term PLN come from? You can find a great discussion about this on a blog post by Alec Couros, but I'll also share what I have come to understand about the differences here.
First of all there was the idea of PLE (Personal Learning Environment), which was a reaction to the VLE (Virtual Learning Environment) represented by platforms such as Blackboard or Moodle. The VLE is all very well, but the big problem with it is that it is usually institution owned. You join when you are a student or employee of an organisation or institution and then when you leave (because you change jobs or stop studying at a particular university, etc) then you will probably have to leave the VLE. This usually means losing all of the learning content you have contributed and becoming divorced from the people you have connected with. Not ideal as it means you have to start all over again somewhere else.
A PLE, on the other hand is owned by the teacher or student and is all about 'small pieces loosely joined' (i.e. a collection of tools that work for you. Soon after the popularisation of the PLE, people started to realise that it wasn't about the tools (i.e. the environment) it's about the people you choose to connect to to enable learning to occur (i.e. your network). So, the idea of a PLN was born, and by all accounts we have David Warlick to thank for this.
Perversely, I have subsequently seen organisations trying to hijack the popularity of the term PLN and use it for what really is a VLE - I went to one presentation at a conference where the presenter talked about how her university was building a 'PLN system' to help their students - what they were in fact doing was building another VLE (i.e. a learning environment that was owned by the university) - bizarre,and totally missing the point!
The benefits a teacher can gain by building a PLN and how best to do it are the reasons why a group of us have started the aPLaNet project - to raise awareness of what this can do for teachers who are reluctant or who don't know how to begin.
