Using a concept mapping software as a knowledge construction tool in a graduate online course
Stemming from a twenty-month pedagogical experience using a concept mapping software for higher education students in an online course, this paper reports findings from what became an exploratory study. The objectives were to support the students knowledge construction process and to stimulate metacognitive reflection. After having read some instructional texts, students used an object-oriented modeling tool called MOT) to graphically represent a network of at least fifteen knowledge units of
Ontological Engineering of Instruction: A Perspective
Foundations and opportunities for an interdisciplinary science of learning
In this chapter, we argue that the learning sciences are poised for a "decade of synergy." We focus on several key traditions of theory and research with the potential for mutually influencing one another in ways that can transform how we think about the science of learning, as well as how future educators and scientists are trained.
Designer integration in training cycles : IEEE LTSA model adaptation
This paper describes an architecture centered on a component model for the course cycle. This model guides a re-engineering process based on the observed use scenarii. It is applied in an institutional framework and uses learning devices provided by the open source community. The architecture integrates the latest works on learning technology standards.
Hypertext navigation and conflicting goal intentions: Using log files to study distraction and volit
This paper describes a theoretical analysis and experimental investigation of difficulty related distraction by conflicting goal intentions in learning and problem solving with hypertext. Log files are used to capture hypertext navigation in the face of opportunities to implement competing goal intentions. We study how differences in task difficulty influence the volitional protection of the current goal intention. First attempts to integrate volitional processes of action control into cognitive
New Types of Careers in the Knowledge Economy ? Networks and boundaryless jobs as a career strategy
Over the last few decades, many countries have found themselves in a context characterized by the spread of the knowledge-based economy (OECD, 1996; Foray and Lundvall, 1995; Soete, 1996; Storper, 1995). The Knowledge Economy implies a farreaching transformation of the labour market, particularly in terms of job mobility and career development (Christensen, 1989). In this context, careers are increasingly fragmented, and people are more mobile in the labour market, with social networks playing a

A Neural Approach for Modeling the Inference of Awareness in Computer-Supported Collaboration
Individuals interacting in a computer supported collaborative learning (CSCL) environment produce a variety of information elements during their participation; these information elements usually have a complex structure and semantics, which make it rather difficult to find out the behavioral attitudes and profiles of the users involved. This work provides a model that can be used to discover awareness information lying underneath multi-user interaction. This information is initially captured in
Simulating Human Tutor Dialog Moves in AutoTutor
This purpose of this paper is to show how prevalent features of successful human tutoring interactions can be integrated into a pedagogical agent, AutoTutor. AutoTutor is a fully automated computer tutor that responds to learner input by simulating the dialog moves of effective, normal human tutors. AutoTutorâs delivery of dialog moves is organized within a 5-step framework that is unique to normal human tutoring interactions. We assessed AutoTutorâs performance as an effective tutor and conve
Student Modelling based on Belief Networks
Belief networks provide an important way to represent and reason about uncertainty significant factors for modelling students. These networks provide a way of structuring such models, and allow a system to use a systematic approach when gathering information about the scope of the students knowledge. This work also provides a theoretically-sound way to update the student model, based on the concept of a dynamic belief network. The relationship to related research is discussed. Finally, the
Using just-in-time information to support scientific discovery learning about geometrical optics in
Many problems that learners regularly encounter during discovery learning with computer-based simulations have been identified. A number of studies have examined different ways of support for discovery learning by facilitating the learning process. This study examines the effect of facilitating access to prior knowledge through just-in-time information. It is expected that access to just-in-time information will foster learning but will not interfere with it. To test these hypotheses, an experim
DIANE (Diagnostic Informatique sur l'Arithmétique au Niveau Elémentaire)
Nous présentons une recherche en cours dont l'objectif est de construire un EIAH, DIANE (Diagnostic Informatique sur l'Arithmétique au Niveau Elémentaire), dont un premier objectif est de réaliser un diagnostic automatique sur un ensemble de problèmes arithmétiques isomorphes à partir des productions de l'apprenant. Une fois le diagnostic effectué, un module de remédiation, en projet, se chargera de proposer des exercices appropriés aux profils des apprenants établis à partir du diag
Affordances – a Merleau-Pontian Account
In this paper, the concept of ‘affordance’ is given an ontological and epistemological explication building on a Merleau-Pontian view of human being as always already being-in-the world in a non-thematized, pre-reflective correspondence of body and world in the concrete activity. A dynamic, agent-centred, cultural-, experience- and skill-relative, but perception-independent, ontology is proposed for affordances. It is argued that this is more in line with the original Gibsonian understanding
Understanding the structure of the set of rational numbers: a conceptual change approach.
In the present article, we argue that the conceptual change approach to learning can apply in the case of mathematics, taking into consideration the particular nature of mathematical knowledge and the neurobiological bases of mathematical cognition. In the empirical study that is reported in this article, we investigated ninth graders' understanding of algebraic and structural properties of rational numbers, from a conceptual change perspective. We make the point that understanding rational numb
The Microevolution of Mathematical Knowledge: The Case of Randomness
In this article, we explore the growth of mathematical knowledge and in particular, seek to clarify the relation between abstraction and context. Our method is to gain a deeper appreciation of the process by which mathematical abstraction is achieved and the nature of abstraction itself, by connecting our analysis at the level of observation with a corresponding theoretical analysis at an appropriate grain size. In this article, we build on previous work to take a further step toward constructin
Platon-1 : quelques dimensions pour l'analyse des travaux de recherche en conception d'EIAH
Le travail présenté dans ce document est centré sur la problématique de la conception des EIAH (Environnements Informatiques pour l'Apprentissage Humain). Dans une première partie, nous proposons une réflexion sur la nature, les objectifs et les difficultés de cette problématique de recherche. Cette analyse conduit à identifier une difficulté centrale, la multiplicité des points de vue qui peuvent intervenir dans un travail lié à la conception d'un EIAH et les incompréhensions prof
2.2 What is natural?
The genetic manipulation of plants and animals and their use in agriculture is one of the most controversial scientific developments of recent times. This unt takes a look at the 'science behind the headlines' and the complex interactions between scientific and social factors. By the end of the unit it's hoped that you will have a clearer idea of both what is GM makes possible as well as what may be thought desirable.
Valentine's Day Song
The video starts by counting 10 hearts, then sings a valentine song to the tune of "One Little Indian." Hearts are on a felt board while the teacher sings. Various shapes are also taught between the song.This video is really great for small children to catch on to.
