The document discusses computer-supported collaborative learning (CSCL) and virtual math teams (VMT) as contexts for studying group cognition and communication analysis. It describes how VMT research at Drexel University uses a collaboration platform and design-based research to capture group interactions for sequential analysis. The goal is to analyze how cognition is accomplished at the small group level through co-construction of knowledge in shared problem spaces, as seen in communication sequences. Group cognition is studied through multiple levels of communication structure.
