La modélisation par objets typés - une méthode de représentation pour les systèmes d'apprentissage et d'aide à la tâche.
Gilbert Paquette · Sciences et techniques éducatives · 1996
We report on a knowledge representation method called "Modeling using object types" (MOT) adapted to the needs of instructional designers who define learning systems and task support systems. A graphic formalism has been constructed aiming at a number of goals : simplicity of use by persons untrained in knowledge modeling techniques, representational expressiveness suited for a large variety of situations and knowledge domains, transparent view of relationships between knowledge units, uncovering a domain 's semantic. The originality of the system lies in its capacity to represent, in an integrated way, four types of knowledge units, facts, concepts, procedures and principles, and six types of basic links between them obeing integrity constraints ; it lies also in its capacity to represent complex model types such as conceptual systems, theories, processes and methods. Based on these basic constructs, we also present a computer assisted model builder which has been used in a certain number of field experiments for instructional design and education systems definition. We conclude by evaluating our results and identifying directions for future work. tain number of field experiments for instructional design and education systems definition.
