Normalising Geometrical Constructions: A Context for the Generation of Meanings for Ratio and Propor
This paper describes aspects of 13 year-olds’ activity in mathematics as emerged during the implementation of proportional geometric tasks in the classroom. Pupils were working in pairs using a piece of software specially designed for multiple representation (symbolic and graphical) of the variation in parametric procedures with dynamic manipulation of variable. In this paper we discuss children’s use of normalising, an activity in which children ‘correct’ the geometrical figures while devel

Jurisdiction in Cyberspace
At its core, jurisdiction is about the boundaries of a sovereign's exercise of its power. What are reasonable constraints on its reach, such that faraway or otherwise unconnected people and institutions can be called to account by the sovereign? Closely related are concepts of choice of law - exactly which sovereign's law to apply to a situation that spans multiple jurisdictions - and venue, which determines the physical location in which the parties are best served to settle their dispute.

Toward Computer-Based Support of Meta-Cognitive Skills: a Computational Framework to Coach Self-Expl
We present a computational framework designed to improve learning from examples by supporting self-explanation ö the process of clarifying and making more complete to oneself the solution of an example. The framework is innovative in two ways. First, it represents the first attempt to provide computer support to example studying instead of problem solving. Second, it explicitly coaches a domain-general, meta-cognitive skill that many studies in cognitive science have shown to greatly improve le

Adaptive and Intelligent Web-based Educational Systems
daptive and intelligent Web-based educational systems (AIWBES) provide an alternative to the traditional “just-put-it-on-the-Web” approach in the development of Web-based educational courseware (Brusilovsky & Miller, 2001). AIWBES attempt to be more adaptive by building a model of the goals, preferences and knowledge of each individual student and using this model throughout the interaction with the student in order to adapt to the needs of that student. They also attempt to be more intelligen

Do two heads search better than one? Effects of student collaboration on Web search behavior and sea
This study compared Pairs of students with Single students in Web search tasks. The underlying hypothesis was that peer-to-peer collaboration encourages students to articulate their thoughts, which in turn has a facilitative effect on the regulation of the search process as well as search outcomes. Both hypotheses were supported by the results. Pairs located the target information more often and in less time than Singles did. Pairs also employed a richer repertoire of search strategies and were

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

L'objectif de cet article est de proposer une modification du langage de modélisation pédagogique IMS-Learning Design en termes de description d'une activité d'accompagnement des apprenants et de la spécification des rôles des acteurs participant à cette activité. Les modifications apportées s'appuient sur un modèle d'organisation du tutorat que nous avons défini. Ce modèle a pour objectifs (1) d'organiser les tâches entre les acteurs tuteur et apprenants, (2) d'assurer auprès des a

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

Scripting argumentative knowledge construction in computer-supported learning environments
Argumentative knowledge construction in computer-supported collaborative learning environments is often weak. This experimental study analyzes two collaboration scripts, which should facilitate argumentative knowledge construction. One script aims to support the construction of argumentation sequences and the other script aims to support the argument construction. These scripts should facilitate the argumentative knowledge construction on both the micro- and macrostructure of argumentation durin

Computer-Supported Collaborative Video Analysis
Video can serve as a powerful medium for analyzing interactions involved in learning activities, for capturing records of teaching for uses in professional development, and for learners to construct or interact with videos expressively, but there have been many barriers to its collaborative uses. The DIVER Project is tackling core problems in advancing computer-supported collaborative video analysis. DIVER establishes a unique video platform for users to control a “virtual camera window” on

The evolution of research on collaborative learning
For many years, theories of collaborative learning tended to focus on how individuals function in a group. More recently, the focus has shifted so that the group itself has become the unit of analysis. In terms of empirical research, the initial goal was to establish whether and under what circumstances collaborative learning was more effective than learning alone. Researchers controlled several independent variables (size of the group, composition of the group, nature of the task, communication

Conceptual Physics
This is a nonmathematical physics textbook, designed so that it can be used either for a semester-length course of the type popularized by Hewitt, or for a shorter course of 8 or 10 weeks. This book is essentially a rewritten version of Discover Physics. The rewrite is intended to do two things: (1) make the book less closely tied to a particular method of teaching, and (2) make it possible to use the book in shorter courses (such as Fullerton College's Physical Science 103A) with the omission o

Gathering Requirements for a Grid-based Automatic Marking System
This paper reports on our experiences using a Creative Requirements [1] workshop approach to elicit requirements for a Grid-based automatic marking system. The research was conducted for ELeGI, an EU funded project whose goal is to provide a European Learning Grid infrastructure to promote a learning paradigm shift from a teacher-centred approach to a learner-centred approach. The automatic marking system uses Latent Semantic Analysis (LSA) to assess the meaning of essays written by computer sc

Introducing E-Learning in a Norwegian Service Company with Participatory Design and Evolutionary Pro
Over a 2-year period, we have participated in the introduction of e-learning in a Norwegian service company, a gas station division of an oil company. This company has an advanced computer network infrastructure for communication and information sharing, but the primary task of the employees is serving customers. We identify some challenges to introducing e-learning in this kind of environment. A primary emphasis has been on using participatory design techniques during the planning stages and ev

Supporting Conceptual Awareness with Pedagogical Agents
This paper describes a series of efforts in building and conceptualizing software agents for distributed collaborative learning. The agents are referred to as pedagogical agents. We have integrated pedagogical agents within two collaborative environments, TeamWave Workplace and Future Learning Environment. The role of agents in these environments differs from past work on software agents in their function as extended awareness mechanisms, focusing on task and concept awareness (conceptual a

Networked Computers’ Incorporated Role in Collaborative Learning
Networked computers are increasingly being used in collaborative learning. To understand what roles networked computers have in collaborative learning over distances, systems developers need conceptual frameworks that address the triadic complexity of knowledge construction, social interaction and technical issues. Some theoretical accounts of this relationship exits, but in terms of usefulness for systems design and how the role of networked is regarded, they have shortcomings. Based on activit
