Hypermedia systems based on the Web for open distance education are becoming increasingly popular as tools for user-driven access learning information. Adaptive hypermedia is a new direction in research within the area of user-adaptive systems, to increase its functionality by making it personalized [Eklu 961. This paper sketches a general agents architecture to include navigational adaptability and user-friendly processes which would guide and accompany the student during hislher learning on the PLAN-G hypermedia system (New Generation Telematics Platform to Support Open and Distance Learning), with the aid of computer networks and specifically WWW technology [Marz 98-1] [Marz 98-2]. The PLAN-G actual prototype is successfully used with some informatics courses (the current version has no agents yet). The propased multi-agent system, contains two different types of adaptive autonomous software agents: Personal Digital Agents {Interface), to interacl directly with the student when necessary; and Information Agents (Intermediaries), to filtrate and discover information to learn and to adapt navigation space to a specific student

De recentes directives ministerielles francaises (BO n° 25, 2008) ont impose aux enseignants de l'ecole primaire de consacrer deux heures par semaine de leur temps de travail a une Aide Personnalisee aux Eleves (APE). Au-dela des enjeux politiques et des tensions legitimes, s'est pose la question du contenu et de la pertinence de ces temps d'APE alors qu'aucun temps de formation supplementaire n'a ete prevu par le ministere. A l'ecole maternelle, l'objectif prioritaire etant la maitrise de la langue des eleves de trois a six ans, les APE peuvent theoriquement etre l'occasion pour les enseignants de mettre en place des situations d'interactions langagieres individualisees, ce qui est difficilement realisable avec le groupe classe. Neanmoins, reste la question de la conception et du contenu de ces temps d’echanges qui impliquent necessairement une reflexion sur les processus d’apprentissage du langage oral

L’objectif est de montrer que, naissent parfois pour gérer les hétérogénéités scolaires des propositions de nature à remettre en cause divers schèmes sur lesquels reposent des représentations usuelles des savoirs et de leur transmission, de la structure de l’intervention didactique et de la formation des enseignants

We present algorithms for computing approximate distance functions and shortest paths from a generalized source (point, segment, polygonal chain or polygonal region) on a weighted non-convex polyhedral surface in which obstacles (represented by polygonal chains or polygons) are allowed. We also describe an algorithm for discretizing, by using graphics hardware capabilities, distance functions. Finally, we present algorithms for computing discrete k-order Voronoi diagrams
