摘要：The aim of this paper is to contribute to increase reusing of pedagogical scenarios by
teachers and trainers. We focus on the educational modelling languages framework, and try to purpose
a life cycle model for learning scenarios and describe with another model the different angles of a
learning scenario. We also work on the functions that could be made available to the concerned users
within new computer based environments.
