David McDonald, director of emerging technologies and an associate professor in the Atlanta-based university’s business school, is inviting students to text message questions to their professors, who post the texted questions on an overhead screen.

Students’ names and phone numbers are not included in their on-screen questions, but text-message queries will raise students’ class participation grades. Each question is screened before it’s posted on the ticker for the class to read.

“Rather than trying to fight [texting], let’s use it,” McDonald said, adding that that text system has a “very strict” filtering feature that censors obscenities. “If they’re going to be doing it anyway, have them pay attention to what their teacher is saying, not what Ashton Kutcher is Twittering.”
