摘要：Development of distant learning has induced the recent emergence of educational
modelling languages, such as IMS Learning Design. These solutions aim to describe learning
scenarios in order to define the organization of activities integrating digital resources. Recent research
works wonder about appropriateness of such languages according to the uses, needs and
representations of teachers and instructional designers. This paper presents first results of CAUSA
project (in French stands for Collecting and Analysing Uses of Scenarization of Activities). One main
goal of this project is to evaluate existing practices in this domain.
