The problem in communication between students and lecturers in large classrooms has increased substantially in last couple of years because many students do not participate in classroom discussions. To engage students into dynamic classroom participation, universities often encourage students to use audience response systems (ARS). By increasing the interactivity between lecturer and students, the dynamic student participation improves and the learning outcome is expected to rise.
The progress in the mobile technologies has influenced new approaches in developing ARS. In this paper, we discuss the need for mobile ARS and we propose a new architecture for developing those systems. Furthermore, we present details from our reference implementation of the proposed architecture, named Click’N’Gage, together with some of the crucial design decisions we took while developing the system. The paper closes with a short evaluation of the system, together with few ideas on how the system could be improved in the future.
