• Students in chemistry lectures were encouraged to use Twitter.com to ask and answer questions during and after lectures. Across 12 lectures, 49 students from a total enrollment of 485 generated 112 messages, of which 68% were germane to the course. Among users and nonusers alike, 77% reported Twitter made it easier to ask questions, but 66% also reported the messages intruded on lectures.
