Within in a re-engineering context, we consider that the designer of a pedagogical situation is the actor who is the most able to describe his observation intentions. This description must be done at the same time as the pedagogical scenario development. In this paper, we present a process that does not rely on the educational modeling language used by designers and which aims to support them in their observation scenario modeling task. This process relies both on a language, UTL (Usage Tracking Language), which allows the description of tracks that they wish to obtain and their linking with tracking objectives associated with used language concepts, and also on the introduction of filters. Once applied to the pedagogical scenario under construction and to the used language model, these filters open up potentially interesting tracking possibilities, that we will call “recommendations”.
