Design of argument diagramming for case-based group learning

Abstract

Motivation -- Argument diagramming tools are likely to be a significant feature of future virtual learning environments. In such environments, where communication is typically computer-mediated and predominantly textual, communication can be integrated with argument diagramming. We report on an exploratory investigation of this design concept.Research approach -- We built a virtual learning environment supporting remote collaborative learning with computer mediated communication by chat text and argument diagramming. We examined the effect of using an explicit argumentation scheme to integrate the discussion with the drawing of the argument. We report the results of an evaluation study conducted with this system.Findings/Design -- We found that learners were able to successfully use the argument diagramming system to represent their discussion.Research limitations/Implications -- Although use of the argumentation scheme was limited, the study nevertheless demonstrates the viability of using explicit argumentation schemes.Originality/Value -- The study suggests the potential for embedding schemes more directly into communication tools in virtual learning environments.Take away message -- People are able to use argument diagramming tools to augment their discussion in a virtual learning environment, and argumentation schemes can enhance that augmentation.
