This article on using Twitter in the classroom states that it "helps students develop key skills in listening, information-gathering, multitasking and succinct writing." Twitter appears to be used primarily in Communications, PR, and Marketing classes.
I'm thinking of using Twitter in my management classes this fall-either as a visual aid for student presentations or as a way to review for exams. I would be curious to hear how others are using this technology.
Thanks to Wendy Drexler for pointing me to the article.
