“Digital Didactic Designs for Group Cognition”
Professor Dr. Gerry Stahl,
Drexel University, USA
Abstract. Designing digital didactics involves multiple dimensions of innovation, including the collaboration technology, the domain-specific curriculum, the social practices for collaborative learning. Such design requires iterative cycles of theorizing, development, usage trials and formative evaluation. The Virtual Math Teams (VMT) Project has pursued this in an extended attempt to introduce students to collaborative dynamic geometry. Students work together virtually on laptops or tablets to explore GeoGebra figures and to construct their own objects with desired dependencies. This symposium presentation will look closely at project data to see how students engage in group cognition, how it differs from individual learning and how it can be analyzed. This will suggest how group cognition may be an appropriate goal for digital didactic design.
Gerry Stahl is Professor Emeritus in Informatics at Drexel University in Philadelphia, USA. He has doctorates in philosophy (the phenomenological and critical-theory traditions) and computer science (AI, CSCL, CSCW, HCI). He is the founding Editor-in-Chief of the International Journal of Computer-Supported Collaborative Learning and was Program Chair of the CSCL 2002 conference and co-Chair of CSCL 2011.
