I'm sure everyone knows wikipedia, but have you ever edited it?
I have - it's a strangely exciting feeling! (OK so I'm sad and have absolutely no life!)
Wikis are also very easy to create and another potential tool for the classroom.
I thinking about what would be some good ways to use wikis in the classroom. What about interactive glossaries, where kids added words they'd found on the internet and included definitions etc.
Or what about a place to put mistakes found in the media and online?
Or perhaps a group-created story or a written history of the suburb?
Limitless potential - once you get the hang of it!
