CARRRE : un modèle de caring pour le support aux communautés d'apprentissage
Nous présentons un cas de formation à distance à l'Université de Central Floride regroupant 1200 étudiants chaque semestre. Après une étude exploratoire auprès des apprenants et des enseignants, nous nous interrogeons sur l'efficacité des EIAH dit « socialement prescriptifs ». Malgré des règles précises, les apprenants quittent l'environnement de la formation et se regroupent sous forme de communautés d'apprentissage efficaces. Après avoir exploré les différentes théories dis
Looking at Learning...Again, Part 1: Workshop 8. The International Picture
This workshop offers an opportunity to investigate various aspects of the Third International Mathematics and Science Study (TIMSS), other than the test scores themselves. Distinguished Professor of Educational Psychology William Schmidt presents differences in curricula, textbooks, and teaching practices around the world, and a group of community members discuss how the TIMSS results reflect societal and cultural values.,This segment concerns "tracking" and sets the stage through educator dialo

SAP "disappointed" by Oracle damages
Germany's SAP says it's "disappointed" by a U.S. jury's decision that it has to pay Oracle $1.3 billion for software theft - damages which could be the largest-ever for copyright infringement.
The impact of simulator-based instruction on the diagramming of the interaction of light and matter
We examine the conceptual development resulting from an instructional experiment with an interactive learning environment in geometrical optics for introductory high school physics. How did teaching-learning processes come to change the ways in which students depicted various everyday optical situations in paper and pencil graphical representations? We view conceptual development as a process resulting in part from increasingly aligning one's practices to a target community by means of participa
The Collaborative Visualization Project: Shared-technology learning environments for science learnin
Project-enhanced science learning (PESL) provides students with opportunities for "cognitive apprenticeships" in authentic scientific inquiry using computers for data-collection and analysis. Student teams work on projects with teacher guidance to develop and apply their understanding of science concepts and skills. We are applying advanced computing and communications technologies to augment and transform PESL at-a-distance (beyond the boundaries of the individual school), which is limited toda

Lessons Learnt from CSCL to Enrich E-Learning
Computer Supported Collaborative learning (CSCL) is nowadays well mature and it is able to set guide-lines to enrich e-learning. On its side, e-learning does not fully exploit its potentialities yet. Suggestions from CSCL could be useful to empower the presence on the e-learning on the market and would foster a vision of learning as not a simple further "commercial product". The European Commission funded many projects involving several countries, numerous students, teachers and researchers, a
Towards On-Line Services Based on a Holistic Analysis of Human Activities
Very often computer scientists view computerization of services in terms of the logistics of human-machine interaction, including establishing a contract, accessing records, and of course designing an interface. But this analysis often moves too quickly to tactical details, failing to frame the entire service in human terms, and not recognizing the mutual learning required to define and relate goals, constraints, and the personalized value of available services. In particular, on-line services t

Nous nous intéressons à la modélisation des connaissances des élèves dans le domaine de l’algèbre. Notre travail utilise les traces des actions des élèves recueillies dans l’environnement informatique Aplusix. Pour capturer une connaissance, il est essentiel de tenir compte de la persistance et de la stabilité d’une action que ce soit dans la durée ou dans la situation. Cependant, deux actions peuvent paraître, de prime abord, contradictoires. Associées au contexte dans lequel
Determining the Sources of Delay in a Distributed Learning Environment
In the context of LeGE-WG we expect to see the Open Grid Services Architecture (OGSA) being used as a guiding framework for the future deployment of Distributed Learning Environment (DLEs). OGSA is totally service-oriented and it has been known for sometime that Quality of Service (QoS) is key to the success of DLEs. Delay in particular, as experienced by the end user, is one of the key QoS parameters for a DLE. This paper describes techniques for identifying sources of such delay, and a model f
