We have developed and implemented a Web-based wireless classroom interaction system in a large-enrollment introductory physics lecture class that uses HP handheld computers (PDAs) to facilitate real-time two-way student interaction with the instructor. Our system is ahead of other "clicker" based PRS (Personal Response System) that is limited to multiple-choice questions. Our system allows for a variety of questions. It also allows for adaptive questioning and two-way communication that provides real-time feedback to the instructor. We have seen improved performance on course assessments through use of PDAs compared to PRS in the same class. We have also shown that students who use PDAs more often in class are more likely to perform better in the course.
