|Abstract:||The Virtual Math Teams (VMT) Project is exploring an approach to the teaching and learning of basic school geometry through a CSCL approach. As one phase of a design- based-research cycle of design/trial/analysis, two teams of three adults worked on a dynamic- geometry task in the VMT online environment. The case study reported here analyzed the progression of their computer-supported collaborative interaction, showing that each team combined in different ways (a) exploration of a complex geometric figure through dynamic dragging of points in the figure in a shared GeoGebra virtual workspace, (b) step-by-step construction of a similar figure and (c) discussion of the dependencies needed to replicate the behavior of the dynamic figure. The teams thereby achieved a group-cognitive result that most of the group members might not have been able to achieve on their own.|
