We can model our virtual environment MTF by the next spaces:

public space group space

individual space team space

an observer system of use for all spaces

Patras 21 July 2006

In each space, we can find : Actors, tools, resources and activities.

supervisor tools agent

supervisor resources agent

supervisor activities agent

supervisor actors agent

The agent hierarchy of our reporting system is made around several supervisor agents :

4. Implementation4. Implementation

We have chosen the MaSE methodology (Multiagent System Engineering) for the development of our software agents.

and we have chosen JADE (Java Agent Development Framework) for the construction of the multi-agents systems.

Our experimentation shows the importance of an observer system in eLearning platform. Its principal vocation is to provide the various actors responsible for this formation (tutors, designer, administrator, etc.) very useful information to control and evaluate a training session.
