This article presents a framework for the cognitive diagnosis of learners' errors in an interactive learning activity occurring in an intelligent learning environment. The proposed framework supports the implementation of an authoring tool. This...

A Didactic resource (DR) is a tactile means of putting information at a student's fingertips in order to allow him or her to acquire certain information or reinforce and test existing knowledge. DRs are crucial to any computerized learning system....

This paper presents a system called Cyberscience 1 dedicated to distance education. The learning interface of Cyberscience includes a component consisting in activating an interactive multimedia simulation in which the student can carry out direct ...

The integration of Information technologies into the educational system has spurred the creation of new courses to effectively train teachers. Hypermedia environments are becoming essential tools for the enrichment of pedagogical values in the...

This paper presents a system called Cyberscience 1 dedicated to distance education. The learning interface of Cyberscience includes a component consisting in activating an interactive multimedia simulation in which the student can carry out direct...

In order to face up challenges in the e-Learning community, it is essential to be able to integrate instructional strategies in learning objects, in a flexible way. The Knowledge Puzzle is an on-going research project aiming at dynamically...

This paper describes some fundamental learning mechanisms implemented in a cognitive autonomous agent, CTS (Conscious Tutoring System). We propose a model that sustains "conscious" and "unconscious" learning as a means to increase the agent's...

The ExploraGraph interface was designed to facilitate interaction in the context of distant learning. It was developed as an alternative to simple web interaction, in order to increase flexibility, visibility, and structure in the learning...

In the last few Years, virtual laboratory has become an important part in online courses. Some of those virtual labs involve intelligent behaviour. However, this intelligent behaviour is usually hard-coded in the virtual lab and therefore, limit...

E-learning has advanced considerably in the last decades allowing the interoperability of different systems and different kinds of adaptation to the student's profile or the learning objectives. But, some of its aspects, such as E-testing are still...

This paper presents AITS, an architecture for Affective Intelligent Tutoring Systems (ITS). In order to promote a more dynamic and flexible communication between the learner and the system, we integrate two adaptive emotional agents in a multi-agent ...

This paper presents the Knowledge Puzzle, an ontology-based platform designed to facilitate domain knowledge acquisition from textual documents for knowledge-based systems. First, the Knowledge Puzzle Platform performs an automatic generation of a...

In the field of e-learning, a popular solution to make teaching material reusable is to represent it as learning object (LO). However, building better adaptive educational software also takes an explicit model of the learner’s cognitive process...
