Twitter catching on with teachers

More and more teachers are finding social media, and Twitter in particular, very useful. According to Renee Hobbs, professor at Temple's School of Communications and Theater and founder of the Media Education Lab at the university, important assets of Twitter are the 140-character limit and "hashtag" function, which allows a user to attach to a message a unique identifier code for anyone interested in a particular topic. "Those two things give it a certain edgy powerfulness that do make it unique," Hobbs said. Twitter also allows teachers to check in when they only have 45 minutes before their next class, for example, she said.
