Designing Virtual Learning Centers
Virtual universities and work-place virtual institutes are seen, more and more, as a solution to the huge education demand of the knowledge society. I will limit my subject here to the design of Virtual Learning Centers, seen as the pedagogical heart of a virtual educational institution. This is where courses or learning events are designed, constructed and delivered using the Internet and its many communication possibilities. Many models are available for these learning events. High-tech classr
Delivery of Learning Design: the Explor@ Systems Case
The IMS Learning Design Specification (IMS-LD) presents new challenges to learning delivery systems. To comply with this specification, delivery platforms must understand different learning strategies and course structures, must manage multi-actor environments, must allow for standard learning objects integration, must deal with conditions and rules to be validated on runtime and must support notifications. In this chapter, we take a look at these requirements from the viewpoint of an open deliv
A Computational Approach to the Discovery and Representation of Lexical Chunks
Lexical chunks have in recent years become widely recognized as a crucial aspect of second language competence. We address two major sorts of challenge that chunks pose for lexicography and describe computational approaches to addressing these challenges. The first challenge is lexical knowledge discovery, that is, the need to uncover which strings of words constitute chunks worthy of learners attention. The second challenge is the problem of representation, that is, how such knowledge can be
Les graphes argumentatifs interactifs sur Internet : sont-ils plus efficaces comme média du débat
Nous présentons les résultats d'une expérience menée dans le cadre du projet européen SCALE. Le but de cette recherche était d'étudier l'influence du type d'utilisation du graphe argumentatif durant des débats pédagogiques sur Internet. Précisément, il s'agissait de savoir sur le graphe argumentatif était plus efficace lorsqu'il était utilisé comme médium du débat (C1) ou comme moyen de le représenter (C2). Dans cet objectif, nous avons évalué à l'aide d'une méthode original
Patrons d'exercices pour Aplusix Une étape du développement de l'EIAH occasion d'un travail entre
Au cours du développement de l'EIAH APLUSIX, il y a eu de nombreuses occasions d'un travail partagé entre informaticiens et didacticiens. Quelques-unes sont décrites succinctement. Lors de la mise en place de patrons d'exercices et d'une carte de tests, une coopération plus approfondie a eu lieu, en respectant les disciplines de chacun. Cette mise en place de patrons d'exercices est décrite plus longuement.,Preprint
Hypermedia as a means for learning and for thinking about learning
This paper is about the design and realization of an experimentation with a hypermedial system, IPER-3, facing the three ‘classical’ problems in the history of mathematics (trisection of the angle, quadrature of the circle, duplication of the cube) and some issues which have developed around them. The aim of the work is to study the opportunities provided by hypermedial systems in dealing with topics of interest for the training of teachers and/or for class work, exploiting the possibility o
Case Study of Virtual Organization Learning and Knowledge Testing Environments
The proposed web-based knowledge assessment is based on flexible educational model and allows to implement adaptive control of learning process as well as to implement knowledge testing environment according to the requirements of student's knowledge level, their personal abilities and his subject learning history. The learner knowledge model can be constructed as a sub graph of the global knowledge domain graph. The paper presents the architecture of student self-evaluation and on-line assessm
Software Interoperability Problems and E-Learning
Grid applications are special cases of networking applications. In order to investigate potential applications of Grid technologies to e-learning we discuss in the following some current applications of network technologies in e-learning as they have occurred at the University Koblenz-Landau. At the appropriate points we shall indicate demands that our e-learning applications pose to the underlying network services and mention, how they might benefit from resource sharing as potentially offered
A device helping learners to self-assess themselves
In this paper, we introduce the architecture of an environment, which aims at helping learners in their self-assessment process. We show how we integrated three systems to build an experimental device based on this architecture. We then present the experiment we conducted to show the utility of this device and also to validate our hypothesis that it is easier for learners to self-assess themselves from an exercises-point of view than from a knowledge-point of view.
Teaching and Learning: Research Briefing
An important aspect of schooling is to enable students to enter new knowledge worlds, such as the world of history, of English, of foreign languages, of science, of music, or of mathematics. In the InterActive Education project we have worked in partnership with primary and secondary school teachers, to investigate ways in which information and communications technology can be used to enhance learning, with a particular focus on improving subject knowledge.,Research briefing
Computer-Supported Scripting of Interaction in Collaborative Learning Environments: Framework on mul
Collaboration scripts aim to facilitate effective interaction patterns for collaborative learning that do not occur spontaneously. So far, diverse non-generic scripts have been conceptualized and investigated in CSCL environments. The specification of collaboration scripts aims to provide a common terminolgy for describing scripts and to abstract the core design principles of scripts to better understand effects and mechanisms of collaboration scripts and to apply and re-apply collaboration scri
The role of interactive visualizations in the development of concepts of logic.
The main objective of the experiments described in this paper is to examine whether instructional variables often used in learning empirical sciences can also be used to facilitate the development of knowledge and skills in the formal sciences, particularly in learning logic. In learning empirical sciences, many positive effects have been reported which can be accounted for by the use of visualisation techniques, multiple representations and possibilities for the learners to interact with repres

Working in ToonTalk with 4- and 5-year olds
We aim to find ways, tools and/or techniques that allow children in this age span to use programming language concepts to express rules and play with them. ToonTalk, with its visual, animated environment, and program-by-example methodology, seemed a very nice tool to start with. On this paper, we will present our experience using Portuguese ToonTalk with 7 children (5 were 4-year olds, 2 were 5- year olds), in Vila Real (Portugal) kindergartens, from May to June of 2000. The most encouraging res
Is support really necessary within educational games?
Games can be powerful learning devices because of their interactive and multimedia capabilities, and their abilities to keep students motivated, active, deeply immersed and engaged for sustained periods of time. Yet the extent to which this translates into more effective knowledge and skill acquisition is not clear from the research reported so far. Several researchers have stressed that support tools should be added to game environments to ensure that learning takes place. In this paper we will

A methodological note on modeling the effects of race: the case of psychological distress
Psychological distress is an important indicator of the mental well-being of the population. Findings regarding racial differences in distress are inconclusive but may represent an important pathway through which disparities exist across a number of physical health outcomes. We used data from the 1994 Minority Health Survey, a nationally representative multiracial/ethnic sample of adults in US households, to examine racial/ethnic differences in psychological distress (n = 3623). Our primary stud
