Combining individual and group-level perspectives for studying collaborative knowledge construction
The aim of this article is to identify concepts and methods for studying collaboration in context. The article presents a two-level methodology designed to combine individual and group-level perspectives for the evaluation of collaborative knowledge construction in student groups. The group-level analysis is focused on the students' negotiation processes. A self-report questionnaire gives insight into students' short-term impressions, meaningful activities and personal meanings attached to diffe
Approche pragmatique de conception d'un EIAH : réingénierie pédagogique dirigée par les modèles
L'objectif de cet article est de proposer une démarche de conception participative entre chercheurs et enseignants et de montrer, à l'éclairage de la mise à l'essai d'un dispositif d'apprentissage collaboratif, comment elle se réifie dans un contexte situé. En particulier, nous présentons comment le processus d'ingénierie et de réingénierie guidé par le modèle de conception du scénario pédagogique permet aux enseignants de s'approprier, de concevoir et d'intégrer dans leurs prat
Une aide à l'interprétation de traces : application à l'amélioration de scénarios pédagogiqu
Nous nous intéressons dans cet article à l'observation au sein d'un EIAH. Notre objectif est de comprendre le comportement des apprenants et, à plus long terme, d'améliorer les scénarios pédagogiques. Dans un premier temps, nous montrons comment récupérer des observations depuis différentes sources. Dans un second temps, nous proposons une méthode permettant de composer une trace à partir de ces observations. Cette trace reflète l'activité de l'apprenant et servira de base à l'inte
Vers des aides logicielles à la compréhension de textes documentaires scientifiques pour les élè
La compréhension d'un texte documentaire par cent vingt élèves du CM2 (5e année primaire) a été évaluée dans quatre conditions expérimentales, en faisant varier d'une part le type de notes d'aide (notes explicitant la « base de texte » vs. notes aidant à construire le « modèle de situation »), d'autre part le support (présentation sur papier vs. présentation hypertextuelle sur ordinateur). La condition où des notes « modèle de situation » sont proposées sur écran d'ordinat

Dans ces conditions, lexpérience de chimie est modifiée par rapport à une si
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.

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
Internal and external collaboration scripts in web-based science learning at schools
Collaboration scripts can help learners to engage in argumentation and knowledge acquisition. However, they might have differential effects for learners holding differently structured knowledge (internal scripts) on argumentation. We investigated how external scripts interact with learners internal scripts concerning collaborative argumentation. 98 students from two secondary schools participated. Two versions of an external collaboration script (high vs. low structured) supporting argumentati
Supporting CSCL with Automatic Corpus Analysis Technology
Process analyses are becoming more and more standard in research on computer-supported
collaborative learning. This paper presents the rational as well as results of an evaluation of a tool called TagHelper, designed for streamlining the process of multi-dimensional analysis of the collaborative learning process. In comparison with a hand-coded corpus coded with a 7 dimensional coding scheme, TagHelper is able to achieve an acceptable level of agreement (Cohen's Kappa of .7 or more) along 6 out
Introduction de nouvelles représentations dans le micromonde Aplusix

Dans le cadre du projet Européen ReMath, nous avons entrepris dintroduire deux nouvelles représentations des expressions algébriques dans le micromonde Aplusix : une représentation mixte Naturelle & Arbre mêlant la représentation naturelle en deux dimensions des expressions algébriques avec une représentation en arbre, et une représentation graphique dans le plan des fonctions et sur la droite des ensembles de solutions des équations. Notre travail emprunte une démarche traditionnel

Mobile Usability in Educational Contexts: What have we learnt?
The successful development of mobile learning is dependent on human factors in the use of new mobile and wireless technologies. The majority of mobile learning activity continues to take place on devices that were not designed with educational applications in mind, and usability issues are often reported. The paper reflects on progress in approaches to usability and on recent developments, with particular reference to usability findings reported in studies of mobile learning. The requirements of
Six Years of Knowledge Networking in Learning Sciences and Technologies
This report presents a series of in-depth reflections about the work of the Center for Innovative Learning Technologies (CILT) from 1997 until 2004. Each member of the CILT team (Principal investigator, postdoctoral scholar, project coordinator and manager) provided their personal reflections on what they, and all of us as a group, have learned from the attempt to stimulate the development and implementation of important, technology-enabled solutions to critical problems in K-14 STEM learning in
Emerging Social Engineering in the Wireless Classroom
Code It! fosters mathematics learning environments where pre-algebra students use handheld technologies to confidently and enjoyably explore and learn about functions. The resources we 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 mathematical functions and their facility with the multiple representations of tables, graphs and symbols. We

Categorisation in Knowledge building
In this paper we explore how students talk and reason when they were exposed to a set of
categories taken from scientific discourse. The scientific categories are built into a web-based discussion forum (Fle) as part of a pedagogical and technological design. The scientific categories are based on the concepts of the progressive inquiry model for knowledge building. Socio-cultural theory with a focus on
concepts like categories and prompting is our theoretical framework. In the DoCTA NSS proje
Learning Objects 4: Applications, Implications, & Future Direction
This is the fourth and final book of this series on Learning Objects (LO). Whereas the first three books were essentially concerned with current developments in the field, this book presents a wide-ranging series of discussions of potential and probable developments in the field. Part I encompasses Chapters 1 through Chapter 5. The focus is upon LO within the context of e-learning and online learning. We realize that our authors (like us) often use the terms "e-learning" and "online learning" in
