Déposé le 10-décembre 2010This thesis fits in the context of multidisciplinary research in Technology Enhanced Learning (TEL) and more particularly in Technology Enhanced Learning Engineering. It concerns more particularly the teacher's activity of designing pedagogical scenarios. The thesis aims to provide secondary school teachers with, models, methods and tools for the design, adaptation, reusing and sharing among designers of scenarios. To this end, this research refers to works on information systems engineering and particularly on goal-oriented requirements engineering, on TEL engineering and on educational research. This research implements a user-centric approach based on various field studies and a co-design approach with practitio...
