In response to Using Twitter in the Classroom...
I've never used Twitter in my classes because many of my students still do not have Internet access on their mobiles. But since I teach and tweet, I do have a couple of suggestions.
1. Twitter inside the classroom: Conduct a "normal" class but have students tweeting at the same time. Setup a projector and computer (with access to the Internet) and project the backchannel on the wall using a decided-upon hashtag. Incorporate the backchannel into the class itself. This technique can also provide instant feedback when determining whether students are getting what you are talking about in class or not.
2. Twitter outside of class: Conduct a backchannel (again using hashtags) that students contribute to outside of class. Incorporate the backchannel in the f2f class as needed. This can also help to see if students are getting it and can contribute to collaborative learning (or colearning) since students can ask questions or complete assignments using Twitter both individually and in groups.
How have you used Twitter in the classroom?
