Wireless interactive teaching by using keypad-based ARS

Lecturing large classes in tertiary education is always a challenge; one of the most difficult tasks being how to gauge students' understanding. Introducing interactivity can alleviate this problem by providing instant feedback that enables the lecturer to clarify problematical points. This is even more crucial and challenging when lecturing to large classes with students from many different cultural backgrounds. This chapter reports the authors¿ experience with a wireless keypad-based system in different classrooms. New deployment strategies used in this project, and educational foundationson which they were based, are explained. The environment and the experience of using the technology from the educator¿s viewpoint are also described. Student feedback is also discussed, and improvements for future use are also proposed.
