Handling Students' Questions

George Williams has a good technique for handling students questions in class:

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.
