Modeling the organisation of the tutoring activity in order to assist the description of educational scenarios

The research presented in this paper focuses on the design of tutoring activity in the context of distance learning environments. Our problematic concerns the assistance for describing the tutoring activity. We aim to specify roles and tutor involvement and also to describe the tools supporting this activity. Using tutoring activity research studies in distance learning environments, we propose a model of tutoring organisation, called Triton. We describe the methodology for using Triton. We propose to extend two EMLs (IMS-LD and LDL) based on Triton. These two cases of study show the interest to enrich the tutoring scenario of the EMLS
