I can't say I am a vigorous Twitter user partially because until this starting course I could not quite come to the understanding of how it might be used in my teaching context. I was introduced to Twitter back in the summer of 2008 during the Hornby Summer School all devoted to teaching using the technology. I remember how excited I felt then but my enthusiasm soon dwindled because back home I could not see a place for it in the classroom. What I completely overlooked is using Twitter to build my PLN. Thanks to some discussions in Multiliteracies I have come to a better understanding of Twitter's potential in this role and hope to start using it this way.
What I want to share with you here is a link to a resource I came across today which discusses uses of Twitter in the classroom: http://www.techlearning.com/article/20896 which lists quite a few uses of Twitter. I came across when thru a list of more resources devoted to Twitter uses in education: http://janeknight.typepad.com/socialmedia/2009/08/twitter-in-the-cl...
I hope you find something useful there for you:)
