Designing a web-based classroom response system

It is well-established in the literature that active participation vitalizes and supports the students' learning process much better than a traditional lecture style. One way of fostering participation in lectures is through pedagogical designs that stimulate cooperative activities among students, using classroom response systems. In this paper we present a prototypical implementation of a classroom response system called PINGO (Peer Instruction for very large groups). PINGO is offered to all instructors worldwide as a hosted service free of charge.
