Trace Analysis in Instrumented Collaborative Learning Environments

Observation activity, on instrumented collective learning situations, enables participants to appropriate themselves corresponding systems in their own practice. In this paper, we focus on the analysis stage of the observation process, but we underline the correlations between the different stages. We present an analysis model and a draft of trace description language. Finally, we explain in an example how an observer (e.g. teacher) can exploit collected information to understand particular episodes.
