Researchers in CSCL have used a wide range of qualitative and quantitative methods to track students' cognitive involvement during collaboration. However, neither individual method suffices the need to capture the dynamic evolvement of students' epistemic engagement in CSCL. We developed Epistemic Synchronization Index (ESI) to quantify students' epistemic engagement and evolvement. ESI reveals the knowledge elaboration process of groups, and it helps researchers as well as teachers to distinguish epistemic involvement between members within one group.
Most distributed and virtual online environments for and pedagogies of computer-supported collaborative learning (CSCL) neglect the social and social-emotional aspects underlying the group dynamics of learning and working in a CSCL group. These group dynamics often determine whether the group will develop into a well-performing team and whether a sound social space emerges. Using a theory-based CSCL framework, two studies evaluated whether two tools, Radar and Reflector, supported cognitive, social and socio-emotional aspects of team development, encouraging promotive interaction and group processing in the teams. While not affecting product quality, tool use did lead to groups who perceived their team as being better developed, as having higher levels of group satisfaction and lower levels of conflicts. The results support that promotive interaction and group processing was increased by using Radar and Reflector.
Pierre Dillenbourg has proved by many articles and speeches to be a hands-on expert on the subject of collaborative learning. He started in 1976 as an Elementary school teacher; he graduated in 1996 in educational and psychological sciences and became PhD in artificial intelligence. At the moment Pierre Dillenbourg is working at the Ecole Polytechnique Fédérale de Lausanne (EPFL) of the Swiss Federal Institute of Technology, partly as a member of the board of directors. I happened to meet him for an interview at the Surf Education Days which were held on the 15th and 16th November in 2005.
