Mobile Devices in Interactive Lectures

In this article we investigate and compare the usefulness of different mobile, wireless devices for use in interactive classroom sessions. Conventional lectures, especially in large lecture halls, face fundamental didactic problems: There is a lack of interaction, it is difficult for the lecturer to deal with individual questions, and it is not easy to maintain a high level of attention. In order to improve interactivity and thus increase attention and learning success, the students can be equipped with mobile, wireless devices, in particular notebook PCs, PDAs or tablet PCs. In this paper we focus on the advantages and disadvantages of these different devices in the Interactive Lecture scenario. We present the results of two case studies carried out at the University of Mannheim. We also review similar projects and public opinion polls from elsewhere. In conclusion we provide the reader with recommendations as to which device is most appropriate for which circumstances.
