In my own classes I've been deliberately vague about what students should tweet about. I didn’t want overly prescriptive guidelines to constrain what might be possible. Instead, I wanted our integration of Twitter to evolve organically. Given this open-ended invitation, I’ve found students tend to use Twitter for class in three ways:
to post news and share resources relevant to the class;
to ask questions and respond with clarifications about the readings; and
to write sarcastic, irreverent comments about the readings or my teaching.
The first two behaviors add to the community spirit of the class and help to sustain student interest across the days and weeks of the semester. The third behavior, when I first noticed it, was an utterly unexpected finding. (And as I've argued elsewhere, it was a good, powerful surprise that legitimated my use of Twitter in and outside of the classroom. I saw students take an oppositional stance in their writing—a welcome reprieve from the majority of student writing, which avoids taking any stance at all.)
