In the next class session, I tried a different approach: The first words out of my mouth were “How many of you have questions?” Almost every hand went up. “Okay, take out a piece of paper and write them all down.” After about five minutes, I started class and explained everything that I had to explain that day. If a student raised a hand, I asked them to add their question to the piece of paper in front of them. When I was finished talking, I asked how many of them still had questions. Only two hands went up, and I was able to answer their questions quickly. Every other question had been answered through my planned introductory remarks.
I’ll be sure to do this again when faced with a similar situation. It’s important for students to have their questions answered, but it’s also important to focus their attention on the very sources of information that will answer those questions. —Handling Overzealous Student Questions – ProfHacker – The Chronicle of Higher Education.
