A Pedagogical Scenario Language for Virtual Learning Environment based on UML Meta-model - Application to Blood Analysis Instrument

Abstract

Training to learn the use and maintenance of biomedical devices have various constraints. In order to complete these trainings, we proposed to use virtual reality based on pedagogical scenarios and Intelligent Tutoring Systems (ITS). In this paper, we first established the existing pedagogical scenario models and ITS. Subsequently we presented our proposal of a formal model based on the concept of learning organization by extension of UML in order to describre some pedagogical scenario and ITS. The use of this model is illustrated by an application of a virtual biomedical analyzer with the aim of learning the technical procedures of the device. Finally, we performed two experiments in order to verify the efficiency of virtual reality training.
