Here's a great post by a K12 teacher who used twitter in a class assignment for the first time..... and the results.
Also on this page are additional links to ideas and programs that use twitter in class.
.... it's a new week starting tomorrow ...... a perfect time to start using a new idea for a lesson!
What would your students say if you told 'em they'd be tweeting for the next assignment?
Check out the twitter tips here....
Have a great week, Jack
