Intelligent Tutoring Systems (ITS)
Dynamic Courseware Generation (DCG)
We have developed an architecture
for dynamic courseware generation which allows explicit representation of teaching
expertise. The instructional course is generated automatically for a given teaching
goal and can be dynamically changed according to specified teaching rules to
suit better the student's individual progress and preferences. The architecture
of the system is based on explicit representation of the structure of the domain
concepts and relationships (what has to be taught) and the instructional tasks
and methods (how to teach). The separate representation of the actual teaching
materials allows better flexibility and individualisation, as well as easier
updating and re-use of ready teaching materials. In this way our approach provides
an alternative to traditional CAL-authoring. Implementations of this approach
in different domains, like electrotechnics and art have been completed and an
evaluation in terms of time for authoring has been carried out. The results
(18 hours of authoring for 1 hour of instruction) are very encouraging. An implementation
of the DCG on the WWW is underway.

Reactive Instructional
Planning
We have developed an architecture
of an ITS based on reactive planning of contents in instruction. It integrates
opportunistic reactions with plan-based (plan-repairs and complete replanning).
This framework allows to implement two radically different teaching strategies,
tutoring and coaching, as well as their interaction within one system. One additional
advantage is the possibility to manage the way of system's reacting by means
of different pedagogical rules. At this point the system has been implemented
and experimented in the domain "Integration of elementary functions".
