Good summary of personal learning networks by Will Richardson:

It’s ingenuous to think that kids are not using personal learning networks already.They are but just not in schools. What teachers need to do is to recognise this use and help kids to import the concept into their school learning in ways that can leverage the power of plns to improve what it is they’re learning.

And they must ensure that kids are doing so safely, ethically and effectively. The best way to do it is to create our own personal learning networks and learn from the experience.
