Un système tutoriel intelligent et adaptatif pour l'apprentissage de compétences en environnement virtuel de formation

Abstract : This work takes place in the framework of the processing of environment for training using virtual reality. More particularly, it integrates the MASCARET project (Multi Agent System for Collaborative and Realistic Environment for Training). The objective is to develop a virtual environment for training dedicated to collaborative and procedural work.

In this context, we defend the thesis that it is possible to integrate a generic and adaptive Intelligent Tutoring System (ITS) in a virtual environment, in order to provide pedagogical aid for the learner and pedagogical assistance for the trainer.

This thesis begins with a study showing the interest of virtual reality and ITS for the acquisition of competences and identifies their difficulties. More particularly, it shows up the necessity of an abstract representation, independent of the exercise to realize, manipulable for pedagogical decision making and connected to the representation of a 3D universe.

Our proposal is a multi-agent system allowing to analyse the action realized by the learner using an informed virtual environment.
The system highlights a set of information, called pedagogical situation, considered relevant to make pedagogical decision.
Then, our study is focused on a pedagogical agent. It suggests assistance to the trainer using the pedagogical situation. The abstraction used allows concrete assistance linked to the domain, to the exercise and to the virtual environment. The behavioural model of the pedagogical agent is based on a hierarchical classifiers system. Thanks to this model, the agent adapts itself to the trainer-learner pair, modifying its pedagogical behaviour by the way of an artificial learning mechanism based on a reinforcement provided by the trainer.

This work is applied to the GASPAR project. The application simulates the plane activity on an aircraft-carrier.
