Within a traditional classroom, teachers easily discover their students in terms of knowledge, motivation or learning style, and can further exploit this knowledge to adapt or optimize their instructions. This task becomes nearly impossible in computer-mediated learning systems, since the observation and evaluation of a learning session are based o...

In this paper we present a model-driven based framework to guide efficiently the design and integration of remote computer experiments into distant learning curricula taking into the account the related educational considerations (especially efficient online teamwork and tutoring support). Our approach is centered on a specific pedagogical object:...

Practical competencies are key components of any computing education curriculum. Today, several computer experiment tools exist, however, these tools are originally intended to experts, and do not integrate very well into the existing online learning environments, in particular, they lack efficient support for teamwork, tutoring and instructional d...

The personalization of Technology Enhanced Learning (TEL) is an area of active research, as proven by the numerous studies concerned with the design of Contextualized Attention Metadata (CAM) systems to offer customized services to learning. These systems, based on the collect of personal data of users, face with certain privacy rules and constrain...

The most important innovations in the distance learning systems in recent years is linked to the introduction of new technologies such as adaptive and intelligent web based educational systems. A prior step for these systems to work is to collect a large volume of Contextualized Attention Metadata (CAM) from the interactions of learners with differ...

In this paper, we describe a web application composed of a set of tools and graphical user interfaces. This application aims at simplifying learning design and enhancing effective learning of distant lab work activities, in the field of computer education. This work is based on the educational concepts of the social constructivism theory, which foc...

The International E-Miage project (IEM) is an engineering curriculum composed of more than twenty international sites that deliver official French degrees. The IEM computational environment comprises many tools, platforms and users that make it very difficult to establish an up-to-date global overview of the whole set of learning entities implied i...

This paper presents a solution for recommending documents to students according to their current activity that is tracked in terms of semantic annotations associated to the accessed resources. Our approach is based on an existing tracking system that captures the user current activity, which is extended to build a user profile that comprises his/he...

Literature shows that Intelligent Tutoring Systems (ITS) are growing in acceptance and popularity because they increase performances of students, leverage cognitive development, but also significantly reduce time to acquire knowledge and competencies. We present an ITS offering the opportunity of evaluating various metacognitive indicators and able...

Nowadays, personalized education is a very hot topic in technology enhanced learning (TEL) research. To support students during their learning process, the first step consists in capturing the context in which they evolve. Users typically operate in a heterogeneous environment when learning, including learning tools such as Learning Management Syst...

La formation International E-Mi@ge regroupe plus de vingt centres d'exploitation nationaux qui délivrent les diplômes de leurs universités respectives à des étudiants résidant à l'étranger ou en activité. Le grand nombre d'acteurs et de plates-formes d'apprentissage impliqués dans cette formation ouverte et à distance introduit une forte complexité...

Annotations are essential when content, form and description of learning objects have to be improved: assessments help teachers to build new and enhance existing resources, whereas suggestions for use allow avoiding former pedagogical mistakes. Reviews submitted by subject matter experts, together with students’ comments, represent a crucial source...

The more learner information is shared across a wide range of heterogeneous applications and tools, the more learner profiles will be relevant, reusable and useful for many systems and environments. This proposal stands on a widely used management standard, and introduces an open and generic learner profile supported by a service-oriented architect...

Even if virtualization technologies are mature enough to deliver remote experiment in a distance-learning context, they are not well-integrated into existing learning environments; as a consequence, they do not provide teachers with any mechanisms to get feedbacks on actions handled by learners. To tackle these issues, this paper presents an approa...

This paper introduces the modeling of a learning context supported by a service-oriented architecture to ensure tracking of profiles and activities of learners involved in Technology Enhanced Learning processes. A distributed architecture including heterogeneous learning systems and tools, together with some tracking components, is experimented wit...

Collecting and sharing attention information represents a main concern within the Technology Enhanced Learning community, as the number of works or projects related to this topic demonstrates it. Attention data are produced by various systems exploited by TEL actors during a learning session, thus raising a difficulty when it comes to collect trace...

In some previous works we suggested a mechanism that offers the opportunity to import, within courseware deployed within Learning Management System, some learning object stored into heterogeneous repositories. Works presented here allow teachers and curriculum managers to be aware of all divergences between the imported learning objects and their e...

Works presented here ensure automatic updates of curriculums deployed within learning management systems as soon as a new version of a given learning object becomes available within a learning object repository. Our approach exploits tracking information collected from heterogeneous learning environments, and relies on two complementary sub-systems...

Works presented in this paper offer teachers and learners the opportunity to express their learning objects assessments and suggestions for use directly from a learning management system, and to store these annotations within a learning object repository. Annotations are thus stored when and where they become relevant. Thanks to an open and standar...

Nos travaux concernent la mise en place d’un environnement informatique fondé sur les standards et normes de la formation ouverte et à distance, et qui permet à de multiples acteurs aux compétences variées et éloignés géographiquement d’intervenir dans un processus de production collaborative et de diffusion à grande échelle d’objets pédagogiques e...

This paper addresses the challenge of providing users with personalized learning resources by gathering and sharing attention information.

RÉSUMÉ. Plutôt que d'attendre que les ressources pédagogiques soient finalisées pour confier la tâche d'indexation à une seule personne, nos travaux s'intéressent à un renseignement progressif des métadonnées réalisé par de multiples acteurs tout au long du cycle de vie de l'objet pédagogique et de ses métadonnées. Nous proposons une démarche pas-à...

RÉSUMÉ : Cet article propose une approche conduite par les modèles pour la gestion des traces d'activité des utilisateurs au sein de systèmes d'apprentissage hétérogènes instrumentés par les technologies Web. Un modèle UML générique de traces permet de structurer et d'ajouter une sémantique claire aux données observées, auquel est associée une arch...

This paper suggests a model driven approach dedicated to the management of tracking data resulting from users activities within heterogeneous learning systems based on internet technologies. A generic UML model describing traces allows to structure and to bring semantics to observed data, while a distributed and decentralized architecture makes it...

As learning management systems and learning object repositories are two separate concerns, it often makes sense to make them together. In previous work, we presented a tiered architecture that includes a middle layer for communication and exchange of learning objects between these two kinds of system, but we set up a basic and static authentication...

In previous work, we presented a tiered architecture based on e-learning standards that includes a middle layer for communication and exchange of learning objects between Learning Management Systems (LMS) and Learning Object Repositories (LOR). Here, we apply this architecture to the International E-Miage (IEM) project, an Information System Engine...

To allow multiple professionals to design and realise together a specific learning object (LO) by using a repository that store and index their several modifications, we need to represent the different steps followed by a LO and its metadata throughout its lifecycle. Here, we study various initiatives related to this issue and notice significant di...

The paper explores the capabilities of a metadata framework based on learning technologies to make learning management systems (LMS) interoperate with learning object repositories (LOR), so that the LOR can obtain information from the LMS context that facilitates the retrieval of existing and insertion of new documents. The study distinguishes two...

This article investigates the capabilities of a Computing Environment for Human Learning (CEHL) to provide two complementary services that lead to the learning objects virtualization : a single view of a set of resources stored in various Learning Object Repositories (LOR), and an easy access to these resources through the use of Learni ng Manageme...
