A Tabletop System to Promote Argumentation in Computer Science Students

This study explores the design of a tabletop system that seeks to bolster the argumentative skills of Computer Science students. A set of four design guidelines - positive interdependence, stages, interference, and awareness - were derived from user research and used for designing and prototyping a multi-display tabletop application. Four students evaluated a video prototype; the overall results showed that the application's features have great potential to support the design guidelines. Moreover, students' impressions about the prototype's enforcement of positive interdependence indicate possibilities for augmenting argumentation opportunities. Steps for future work are presented.
