Minimalist instruction for learning to search the World Wide Web.
This study examined the efficacy of minimalist instruction to develop self-regulatory skills involved in Web searching. Two versions of minimalist self-regulatory skill instruction were compared to a control group that was merely taught procedural skills to operate the search engine. Acquired skills were tested on Web search tasks and search tasks in an online library catalogue. Self-regulatory skill instruction was found to increase practice time by 25%. However, it did not enhance search perfo
Self-directed learning in simulation-based discovery environments
SIMQUEST1 is an authoring system for designing and creating simulation-based learn-ing environments. The special character of SIMQUEST learning environments is that they include cognitive support for learners which means that they provide learners with support in the discovery process. In SIMQUEST learning environments we try to find the balance between direct guidance of the learning process and sufficient free-dom for learners to regulate the learning process themselves. In this article we de-
Supporting peer interaction in online learning environments
This paper reports two studies into the efficacy of sentence openers to foster online peer-to-peer interaction. Sentence openers are pre-defined ways to start an utterance that are implemented in communication facilities as menuÂ’s or buttons. In the first study, typical opening phrases were derived from naturally occurring online dialogues. The resulting set of sentence openers was implemented in a semi-structured chat tool that allowed students to compose messages in a free-text area or via se
Effects of pictures, age and experience on learning to use a computer program
This study examines the effects of pictures of screen captures and input devices on documentation for older novices. There was no main effect of pictures, but there were statistically significant interactions between the type of picture and the factors of age and computer experience. As predicted, the most optimized designs—the ones presenting screen captures—moderated the negative effects of age. We argue that screen captures help reduce two problems in the cognitive area that are especially
Le rôle de l’ingénierie ontologique dans le domaine des EIAH
Dans cet entretien, Riichiro Mizoguchi nous révèle ses pensées les plus profondes sur le rôle que joue l’Ingénierie Ontologique (IO) dans le domaine des EIAH. Il insiste sur la nature conceptuelle d’une ontologie, faite pour pouvoir partager des connaissances entre humains et ordinateurs, et entre ordinateurs. Conceptualisation, partage et réutilisation sont donc les concepts-clés d’une ontologie. Dans le domaine des EIAH, le rôle de l’IO n’est pas de modéliser les connaissances po
New authoring frameworks for integrating collaborative learning technologies
This workshop is intended for CSCL researchers and/or their technologists who are interested in designing and then actually creating rich, interactive learning materials in a technology-enhanced environment. The workshop will present the work of two complementary approaches to the design of environments for collaborative, productive and open ended learning, such as collaborative inquiry learning and learning by design. Participants bring in their own issues and work on the design of learning env
Apport de l’ingénierie ontologique aux environnements de formation à distance

Herzberg : une simulation multimédia à interactivité variable
Herzberg est un environnement de simulation multimédia permettant de visualiser et d’explorer la vibration et la rotation des molécules. Il permet de créer des documents formés d’un ensemble de pages affichant une ou deux molécules dans des configurations prédéfinies; un texte et une voix d’explication peuvent être associés à chaque page. Il est possible de fixer pour chaque document le niveau d’interactivité. On peut également, sans effectuer de programmation, ajouter de nouvell
OMAGE : Outils et Méthode pour la spécification des connaissances au sein d'un Atelier de Génie E
Les nouvelles technologies de l'information sont entrées au cœur de notre société et provoquent de profonds changements dans notre vie quotidienne, notamment dans le monde du travail. Or le métier d'enseignant n'a pas vraiment évolué, même si les méthodes éducatives changent, car toute tentative d'introduction de l'informatique se heurte à la méfiance des enseignants qui ont peur de perdre leur liberté de choix éducatifs. De plus, les avancées technologiques n'ont d'intérêt que
CEPIAH, a method for Evaluation and Design of Pedagogical Hypermedia
We are working on a method, called CEPIAH. We propose a web based system used to help teachers to design multimedia documents and to evaluate their prototypes. Our tool integrates two modules such as EMPI (Evaluation of Multimedia Pedagogical and Interactive software), and SP/UL/FC, a method for designing pedagogical hypermedia. The EMPI module is used to evaluate multimedia software used in educational context. We structured a knowledge base composed of a list of evaluation criteria, grouped th
Natural Editing of Algebraic Expressions
We call “natural editing of algebraic expressions” the editing of algebraic expressions in
their natural representation, the one that is used on paper and blackboard. This is an issue
we have investigated in the Aplusix project, a project which develops a system aiming at
helping students to learn algebra. The paper summarises first this project. Second it
defines the notion of algebraic expression, and of representation of algebraic expression.
After an exploration of 20 software systems whic
Fostering collaborative knowledge construction with visualization tools
This study investigates to what extent collaborative knowledge construction can be fostered by providing students with visualization tools as structural support.
Thirty-two students of Educational Psychology took part in the study. The students were subdivided into dyads and asked to solve a case problem of their learning domain under one of two conditions: 1) with content-specific visualization 2) with content-unspecific visualization. Results show that by being provided with a content-specific
Advanced video technologies to support collaborative learning in school education and
beyond
The aim of the paper is to characterize two new advanced video technology software systems developed for uses in collaborative learning (DIVER and HyperVideo2), and how they extend the paradigms of video use in classrooms today. The rationale for and characteristics of these tools are described, and early experiences with their use are characterized.
Functioning in the Wireless Classroom
Code It! fosters mathematics learning environments where pre-algebra students use handheld technologies to explore and learn about functions. The resources developed - server-based and handheld software and paper-based student and teacher texts - were packaged as a 20-session unit on code making and breaking and designed to boost students' understanding of functions and their facility with the multiple representations of tables, graphs and symbols. We field tested the wireless system with two te

Changing How and What Children Learn in School with Computer-Based Technologies
Schools today face ever-increasing demands in their attempts to ensure that students are well equipped to enter the workforce and navigate a complex world. Research indicates that computer technology can help support learning, and that it is especially useful in developing the higher-order skills of critical thinking, analysis, and scientific inquiry. But the mere presence of computers in the classroom does not ensure their effective use. Some computer applications have been shown to be more suc
‘Hole-In-The-Wall’ Computer Kiosks Foster Mathematics Achievement - A comparative study
Earlier work at unsupervised playground computer kiosks in rural India, popularly called 'hole-in-the-wall', showed that children exposed to these kiosks learn to use computers on their own and that they are able to clear school examinations in computer science, without any classroom teaching for it. Extending this, our recent research work examines the possible impact on attainments in other curricular subjects, arising from self-directed use of these kiosks. This paper investigates the impact
A Grid Approach to Provide Effective Awareness to On-line Collaborative Learning Teams
Providing collaborative learning applications the possibility to offer continuous awareness to on-line collaborative learning teams is a challenging issue since it is essential to keep participants informed of both what is happening and what happened in the learning group.
Moreover, awareness is the basis to enhance collaboration and improve the individual and group performance since it allows to track and assess the collaborative learning process more objectively and to model students' behavio
The Semantic Aspects of e-Learning: Using the Knowledge Life Cycle to Manage Semantics for Grid and
The aim of bringing semantics to learning content and services is to enable large scale collaboration of e-learning activities over the Grid infrastructure.
As machines and software applications will be ubiquitously involved in enabling and facilitating this collaboration, it requires a common understanding of the domain, in particular at the conceptual level, so that both computers and human participants of the e-learning activities understand and are able to communicate among themselves thoug
