Donald Liu, who teaches a microeconomics course, uses the clickers to pose a multiple-choice question to the 110 students after 10 minutes of covering material, the Minneapolis Star-Tribune reports. As students click their answers, their names appear on a screen, and he can then pick one to explain why he or she answered that way. Advertisement Liu gives students 2 points for a correct answer, one for a wrong answer and zero for not answering at all. Some students have tried to cut class by giving their clickers to friends. But Liu said that by using a seating chart and memorizing his students' faces, he can figure out who is missing -- and send them an e-mail asking them why they weren't in class. The next step is likely to be laptops.
