TELOS

TELOS (Technology-enhanced learning operating system) est un système intégrant un ensemble d’outils pour la création d’environnements Web pour l’apprentissage, la conception ou le travail. Il a fait l’objet d’applications en industrie et de plusieurs thèses de doctorat au LICEF. Il est géré par ontologies et une architecture est orientée service. Il permet la création d’environnements à plusieurs niveaux et l’orchestration de scénarios multi-acteurs pour l’opération de plateformes de conception ou de suivi de cours, ainsi que des interfaces usagers soutenant la téléprésence et la collaboration.

Accès à TELOS


Au cours des dernières années, dans le cadre du réseau de recherche LORNET, l’équipe du LICEF a construit l’architecture et développé TELOS, un système d’opération innovateur pour les environnements d’apprentissage et de gestion des connaissances. Il s’agit d’une nouvelle approche pour les systèmes de gestion de contenu (LCMS/CMS/VLE) .

TELOS

La figure montre l’interface principale de TELOS dans un fureteur Web, avec trois des principaux outils ouverts: le gestionnaire de ressources, l’éditeur de scénario et les gestionnaire de tâches.

  • Le gestionnaire de ressources donne accès à toutes les ressources disponibles, classifiées par types et sujets selon l’ontologie technique à la base de TELOS.
  • L’un des scénarios sélectionné dans le gestionnaire de ressources est affiché dans l’Éditeur de scénario. On voit dans cette interface le graphe d’un scénario d’apprentissage impliquant trois acteurs et quatre unités d’apprentissage organisée en séquence. Des sous-graphes détaillent chacune de ces unités ou modules.
  • Le gestionnaire de tâches permet aux acteurs de réaliser les activités des unités d’apprentissage et d’en consulter les ressources.

The TELOS system embodies  the following characteristics.

  • Global Systemic View. The Virtual Campus (VC) model of TELOS takes a global view to provide cohesion to Virtual Campus activities. At the upper level, an institution can create a global workflow to coordinate the major processes where different categories of personnel interact to provide services to the students. At the next level, more specific workflows are designed and tools, documents and activities are orchestrated into a platform or a portal. Then, within a portal, a number of learning scenarios (courses) or workflows are designed as application portals. Finally each scenario or knowledge management flows is used by end users to produce results.
  • Extended set of actors. Compared to the actual LCMS in operation, and also to our initial VC model, TELOS supports an unlimited set of actors. At any level, in principle, any number of actors can be defined and supported.
  • Better process coordination. The fact that the TELOS system holds a model of the VC processes and support resources leads to better process coordination. Especially in distance universities, this provides better assurance that the quality of services will be maintained when the personnel changes, especially when it must provide products of his activities to other actors.
  • Visible scenarios and workflows. Learning scenarios or workflows can always be consulted in a Web portal interface, changes to components or actors can be seen right away. Each user taking an actor’s role within a TELOS environment can visually see the context of the activities he has to perform, what resources to use or produce and with whom he is to interact with.
  • Flexible and adaptable environments. Each TELOS-based environment operates according to a technical ontology representing the Virtual Campus model, which is part of the system. This enables very flexible and adaptable environments. If a new kind of actor, activity or resource needs to be introduced, this is done simply by modifying the ontology, without changing the main operations of the system.
  • Resource reusability is a goal pursued by many advocates of learning object repositories, but it is not that easy to achieve. Using ontologies to model each resource within the TELOS framework, and adding connecting operations to take care of possible technology mismatches brings solutions to resource reusability problems.
  • System interoperability. With the new TELOS VC model, it is possible to bring different technologies and different platforms to work together. For example, a designer could build a course using a scenario editor in one platform, and transfer it to another platform to add new functionalities, for example personalized assistance. This process can be designed by defining the aggregation scenario between platforms and building ontology alignment operations.
  • Modeling for all. Modeling is not an easy task but it is important enough to be made accessible not only to engineers and technologists, but also to instructional designers, learners and trainers. User-friendly visual modeling languages are made available at all levels of the TELOS system.
  • Focus on learning and work designs. Finally, we hope the proposed approach to Virtual Campus modeling and operation will reduce the technology noise that is often present in eLearning applications when too much time is devoted to solving pure technology problems, instead of focusing on learning problems. We suggest that the activities will be more focused on pedagogy and quality of educational services.
