Situational knowledge in physics: The case of electrodynamics
Major difficulties for a novice physics problem solver are how to interpret new problems and how to combine information given in the problem with information already known. A domain expert, by contrast, has the knowledge to take full advantage of problem features at a glance. It takes a long period of practice to acquire such situational knowledge, and it would be desirable for this to be taught more effectively. As a first step, this requires information on how situational knowledge differs acr

Physics learning with a computer Algebra systems: Towards a learning environment that promotes enhan
To become proficient problem-solvers, physics students need to form a coherent and flexible understanding of problem situations they are confronted with. This is important both for solving problems and for interpreting solutions. Still, many students have only a limited representation of the problems they are working on. Therefore, we devised an instructional approach to promote students' understanding of these problems, and to support them in forming associations between problem features and so

Co-Lab, design considerations for a collaborative inquiry learning environment
Co-Lab is a learning environment for collaborative inquiry learning in which learners can experiment, make models, consult background information and discuss their findings. The complex learning processes in such an environment need to be supported by appropriate features in the software. In this paper we report on how, based on existing literature and specific user and usability studies, we developed a set of design guidelines that were implemented in the software.

MArCo: Building an Artificial Conflict Mediator to Support Group Planning Interactions
The emphasis on building co-operative/collaborative environments has brought out the matter of group interactions. This, in its turn, has highlighted the issue of conflicts, inherent to group problem solving. If well employed, conflicts can act as triggers of cognitive changes, and thus help to refine the group's solution to the task. In this paper, we present a computational framework for detecting and mediating Meta-Cognitive conflicts. The theoretical framework presented here enables a comput

A Comparison of Model-Tracing and Constraint-Based Intelligent Tutoring Paradigms
Two approaches to building intelligent tutoring systems are the well-established model-tracing paradigm and the relatively newer constraint-based paradigm. Proponents of the constraint-based paradigm claim that it affords performance at levels comparable to that of model-tracing tutors, but with significantly less development effort. We have built both a model-tracing and constraint-based tutor for the same problem domain (statistical hypothesis testing) and report on our findings with the goals

Une typologie des fonctions des modèles formels : l'exemple de la biologie
Une typologie des fonctions des modèles est construite à partir d’un cadre théorique (Nifle) permettant de définir le rapport entre modèle et expérience. Il est admis qu’il existe un lien entre la manière dont on modélise en tant qu’expert ou chercheur et la manière dont on apprend à modéliser en tant qu’étudiant, et que ce lien repose sur le rapport expérience/modèle. La typologie est construite pour le cas particulier des modèles formels (utilisant un formalisme mathématiqu

Un dispositif web pour l'enseignement des mathématiques à l'université : quels impacts sur la per
De nombreuses universités en France ont créé des sites Web pédagogiques avec l'objectif de moderniser leur pédagogie et motiver les étudiants. Les étudiants apprennent-ils mieux avec ces dispositifs ? Sont-ils plus satisfaits et motivés pour apprendre ? Nous avons réalisé une étude expérimentale pour évaluer l'apport pédagogique d'un site Web lors de la réalisation de séances de TD en mathématiques pour les sciences de la vie.

The effects of graphical overviews on exploratory behaviour and knowledge acquisition in hypertext e
One of the main and recognized problems of learning with hypertexts is that learners are easily distracted and end up ‘lost in hyperspace’. As a result, they do not acquire complete and adequate knowledge. In this study, we enhanced a hypertext environment with a graphical overview that represented the basic structure of the domain and we designed the layout in such a way that learners were unobtrusively encouraged to follow a sequence of exploration that followed the domain structure. This so

Computational GRIDs and online laboratories
Many projects addressing the creation of online laboratories have been developed recently. They have a common goal: to enable students and professional learners to get hands-on experience without moving from the places where they are. Nevertheless, the found solutions are often very different among them, and interoperability between different online laboratories systems does not exist. In this paper we present our work around the exploitation of Grid technologies for sharing instrumentation and

Interactive learning of nanophysics phenomena
This paper describes a new method of teaching and experimenting nanophysics effects using a nanomnipulator. This nano-manipulator is formed by a multi-sensory platform connected to an AFM and/or to virtual nano-scenes produced by a real-time simulator. The first objective of this work is the evaluation of a custom-made nanomanipulator compared to the use of a classical Atomic Force Microscope (AFM) interface. These instruments are used to teach one-dimensional nano-physical phenomenon, the appro

A Semantic Approach to Discovering Learning Services in Grid-Based Collaborative Systems
CSCL systems can benefit from using grids since they offer a common infrastructure enabling the access to an extended pool of resources that can provide super- computing capabilities as well as specific hardware resources. Adopting a service oriented architecture such as OGSA can further benefit CSCL systems, enabling increased flexibility to adapt and reuse learning software offered by third party providers. However, service discovery is a challenge for educators, since they cannot use their ow
