A symbolic manipulator to introduce pupils to algebra theory
Within the theoretical framework of Vygotsky's theory, the paper presents a new algebra software. The main features of the software are described and their potentialities are discussed. According to the Vygotskian theory, expressions and commands may be thought as external signs of the Algebraic theory, and as such, they may become instruments of semiotic mediation: In other terms they can be used by the teacher, in the concrete realisation of classroom activity, according to the motive of intr
Calculators, graphs, gestures and the production of meaning
In this paper we report an analysis of a teaching sequence in which Grade 11 students were asked to produce some graphs corresponding to the relationship between time and distance of a cylinder moving up and down an inclined plane. The students were also asked to carry out the experience using a TI 83+ graphic calculator equipped with a sensor, and to discuss and explain the differences between their own graphs and the ones obtained with the calculator. We analyze the students' processes of mea

A micoworld to implant a germ of probability
This paper reports on the third part of a long term experiment concerning the introduction of 12-13 years old pupils to the concept of randomness and probability. In the first parts, the pupils analysed the concept of randomness, in daily life and with LEGO-RCX robots. The third part is based on the Random Garden Game (within the programming environment ToonTalk). The pupils are guided towards the concepts of equivalence of sample spaces and of classical probability, through temporary and person
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
ELeGI: The European Learning Grid Infrastructure
The purpose of this paper is to describe the ELeGI Project1. ELeGI has the ambitious goal of developing software technologies for effective human learning and promoting and supporting a learning paradigm shift. A new paradigm focused on knowledge construction using experimental based and collaborative learning approaches in a contextualised, personalised and ubiquitous way will replace the current information transfer paradigm focused on content and on the key authoritative figure of the teache
A Learning Grid for the multichallenge school ECP
The aim of this presentation is to try to define the requirements of a European Learning Grid that would fit best with the challenges and today and future practices of Ecole Centrale Paris. In a first part, after a brief presentation of Ecole Centrale Paris, we describe the actual challenges today practices and the interest of an e-learning GRID. In a second part we describe some potential cases of such system and the associated requirements.
An environment helping teachers to track students' competencies
Our research concerns teaching assistant systems by treating the question of reuse and exploitation of learners’ profiles by the teacher. We propose also that other actors of the learning situation, learners and institutions, benefit from the exploitation of these profiles. In PERLEA project, we want from one hand to model the students’ tracking process, and on the other hand to propose an environment giving software tools to help actors to reuse and exploit profiles of all disciplines, what
Specification of the CoP-oriented knowledge management tool offering basic CoP-adapted KM services
This deliverable proposes a preliminary specification of basic KM services interesting for CoPs. It describes their functionalities, their possible interfaces with other services and with the human user; as well as possible uses of these basic KM services by CoPs. Various tools available among the partners, that could offer some of these basic services, are presented. A web service-oriented architecture enabling to offer all such KM services in a modular way with possible interoperability with o
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.
Metacognition in joint discussion: an analysis of the patterns of interaction and the metacognitive
The aim of this study was to examine metacognition in computer-supported collaborative problem solving. The subjects of the study were 13-year-old Finnish secondary school students (N=16). The Knowledge Forum learning environment was used to support student pairs’ problem-solving task involving polygons in a geometry course. The data consist of the student pairs’ posted computer notes (n=95). To examine metacognition in a social context in the networked discussions, the features and patterns
Students' activity in computer supported collaborative problem solving in mathematics
The purpose of this study was to analyse secondary school students' (N=16) computer-supported collaborative mathematical problem solving. The problem addressed in the study was: What kinds of metacognitive processes appear during computer-supported collaborative learning in mathematics? Another aim of the study was to consider the applicability of networked learning in mathematics. The network-based learning environment Knowledge Forum (KF) was used to support students' collaborative problem sol
Kaleidoscope JEIRP on Learning Patterns for the Design and Deployment of Mathematical Games: Final R
Over the last few years have witnessed a growing recognition of the educational potential of computer games. However, it is generally agreed that the process of designing and deploying TEL resources generally and games for mathematical learning specifically is a difficult task. The Kaleidoscope project, "Learning patterns for the design and deployment of mathematical games", aims to investigate this problem. We work from the premise that designing and deploying games for mathematical learning re
Studying participation networks in collaboration using mixed methods
This paper describes the application of a mixed-evaluation method, published elsewhere, to three different learning scenarios. The method defines how to combine social network analysis with qualitative and quantitative analysis in order to study participatory aspects of learning in CSCL contexts. The three case studies include a course-long, blended learning experience evaluated as the course develops; a course-long, distance learning experience evaluated at the end of the course; and a synchron
Domain Modelling To Support Educational Web-based
This paper describes an approach to web-based authoring of educational material. We define a model for the class of subjects of our interest (those including both theoretical and practical issues). From this model, specific content outlines can be derived as subclasses and then instanced into actual domains. The last step consists in generating interactive documents, which use the instanced domain. Students can explore these documents through a web browser. Thus, an interactive learning scenario
Explication et préceptorat, à propos d'une étude de cas dans TéléCabri
Après avoir présenté un cadre d’étude des processus explicatifs, nous présentons l’analyse didactique d’une interaction téléprésente entre un précepteur humain et son élève. Nous montrons comment l’explication n’est pas une propriété intrinsèque du discours mais un attribut, résultat d’une construction de signification pendant l’interaction du précepteur avec son élève.
