Wireless student response systems - "clickers" - address two of the oldest and most fundamental challenges in teaching: how to engage students, and how to determine if they are learning what you are teaching. Clickers are relatively low cost and easy to use, and their use is spreading remarkably fast throughout the US, with many universities using thousands. Astronomy textbooks may be ordered with coupons for clickers in them. The way the system works is that each student's clicker has buttons a, b, c, d, and e. Any time the instructor wants feedback, he or she asks a multiple choice question. Student responses go to a receiver that plugs into a computer (e.g. the instructor's) showing responses as a bar chart. The chart is often shown to the class via an LCD projector. Clickers give immediate feedback about what each student is thinking. The instructor can decide whether to proceed or to spend more time on a particular topic. Equally valuable, the student learns immediately whether he or she understands the concept the teacher is presenting, without waiting for a test or raising their hand to ask a question. I will present extensive research data that show that when clickers are used well in large lecture classes they increase the engagement of students and improve their learning by a significant amount. Students overwhelmingly like using clickers and believe they increase their learning. They also increase class attendance, typically by 20%. Like any technology it is possible to misuse clickers. Common mistakes made by new clicker users and how to avoid them will be described, as well as "best clicker uses" such as peer instruction. (Peer instruction means that when the class answers are split students have to debate with their neighbour who is right, rather than the instructor telling them.) This presentation will feature a demonstration of the clickers, with one given to each person in attendance.
