Abstract

Economics (82) Economics students enrolled in large lecture-based introductory courses rarely have the opportunity to interact with course content. Because of this they do not gain a deep understanding of the material or the ability to analyze and interpret complex economic events. Classroom experiments have been shown to be useful in aiding student understanding of the material. In the past these exercises have been impractical in large courses. This project is developing wireless classroom technology to allow students in large classes to participate in classroom experiments during the class meeting times. We have assembled a cross-disciplinary group that is creating a learning system that is making it possible to realize the benefits of classroom experiments in large classes. Our vision is of a portable system composed of standard electronic handheld devices (such as PDAs) that communicate with a laptop computer that will organize economics simulations such as markets, public goods environments and economic games. While other researchers are currently working on internet-based experiments, such systems do not translate to large classes unless students complete the exercise asynchronously. The instructor has only very limited ability to revise the game in response to student questions or suggestions. Evaluation is a critical component of this project. We have designed a controlled experiment to collect data on performance in a large lecture course. We are evaluating to what extent this wireless system can improve student outcomes and reduce costs.
