Although many have an aversion to tweeting, the many uses of twitter can add an exciting dynamic to any classroom. It can be more than simply telling your followers what you ate for lunch, or where you went for Easter break. An experiment on the use of social media at the University of Leicester in the UK has shown that Twitter can act as a valuable communication tool, as it developed peer support among students, personal learning networks, and an increase in students arranged social meetings. Try using it to hold a class brainstorm session, analyze the math behind aviral tweet/hashtag, issue a poll to gauge opinion, or communicate with experts in their field.
