To recap, a PLN or Personal Learning Network (because educators love our acronyms) has been around forever. In the past they tended to be the friends, family or colleagues you were to for help and guidance.
How I became a convert to Twitter • The teaching and education community on Twitter is truly inspirational...
Twitter is a fantastic collaborative tool. As teachers, how often do we get to visit other schools? In my experience, very rarely. Twitter has enabled me to collaborate with teachers in schools across the country. Combine this with cloud services such as DropBox and Google Docs and you can create and share resources and ideas quickly and easily.
The site is also a great place for discussion. It is amazing how creative you can be in 140 characters. Teachers, academics, technologists and other experts come together on Twitter to chat and discuss a whole range of topics – you can follow and contribute to these discussions by using hash tags.
