Mixing Microworld and Cas Features in Building Computer Systems that Help Students Learn Algebra
We present the design principles for a new kind of computer system that helps students learn algebra. The fundamental idea is to have a system based on the microworld paradigm that allows students to make their own calculations, as they do with paper and pencil, without being obliged to use commands, and to verify the correctness of these calculations. This requires an advanced editor for algebraic expressions, an editor for algebraic reasoning and an algorithm that calculates the equivalence of
APLUSIX, A learning environment for algebra, actual use and benefits
After a presentation of the APLUSIX system, a learning environment for formal algebra, we describe the use of this system in a French class of grade 10, in particular a sequence devoted to factorisations and equations, and an analysis of the students' work during this sequence. This study exhibits the influence of the tools provided by the software on the construction of competences in algebra. We also report the opinion of a teacher who used the APLUSIX system during one year with this class.
NLP-based scripting for CALL activities
This article focuses on the development of Natural Language Processing (NLP) tools for Computer Assisted Language Learning (CALL). After identifying the inherent limitations of NLP-free tools, we describe the general framework of Mirto, an NLP-based authoring platform under construction in our laboratory, and organized into four distinct layers: functions, scripts, activities and scenarios. Through several examples, we explain how Mirto's architecture allows to implement state-of-the-art NLP fun
Educational Knowledge Based Environment
In this paper a knowledge based environment is represented which facilitates easy creation and preparation of wide range of educational software. The heart of the environment is the knowledge representation tool providing a hybrid knowledge representation formalism combining frames, production rules and logic. The environment is built on the basis of the logic programming language Prolog.
An Evolutionary Approach to Prototyping Pedagogical Agents: From Simulation to Integrated System
We have developed and integrated software agents with two educational groupware systems (TeamWave Workplace and FLE), using evolutionary prototyping and empiricalbased design as development techniques. The resulting prototypes of pedagogical agents (CoPAS, SA-Agent and RuleEditor) provide learners and teachers with increasingly domain-specific support for distributed collaborative learning activities. Employing the evolutionary approach has enabled us to build and evaluate early prototypes of co
Didactical complexity of computational environments for the learning of mathematics
How a microworld is used by students is crucially influenced by the teacher, who has the responsibility of organising the classroom setting in which learning takes place. For this reason this paper focuses on the teacher as a manager of the learning situation, in relation to the students’ construction of meaning. A model of teaching which takes into account interactions between teacher, students and computer is outlined. Although the focus of this paper will be on the teacher, the teacher w
Designing for cross-cultural web-based knowledge building
This paper describes the iterative design of a web-based collaborative workspace used in educational practice, called WebReports. The systemâs unique feature is that it allows participants to discuss mathematical and scientific concepts using programmed animated and interactive models of their ideas. Rather than focusing on the specific features of the collaboration tool, we analyze it as part of a constructionist activity system. We describe the context in which the system was developed an
COW, une plate-forme de support d'exécution de scénarios pédagogiques.
Cet article présente un service de support d'exécution de scénarios pédagogiques conçu pour être intégré dans des plates-formes de formation existantes. Dans un premier temps nous prenons un point de vue ingénierie des plates-formes afin d'identifier les processus de conception et d'utilisation ainsi que les acteurs qui y sont associés. Dans un deuxième temps nous présentons les caractéristiques nécessaires que doit offrir notre service afin que les différents acteurs puissent gé
Socrates Mailbox - Rapport de Synthèse
Le projet Mailbox (1996-1998) est un projet d’observation sur deux ans qui s'est déroulé dans le cadre du sousprogramme Enseignement Ouvert et à Distance — Open and Distance Learning (EOD-ODL) du Programme SOCRATES de la Direction Générale XXII de la Commission européenne. Lancé en septembre 1996 ce projet a pour objectif d’étudier par une approche ethnographique l’utilisation des systèmes de communication électronique dans l'enseignement primaire et secondaire.

Cabri-géomètre as a mediator in the process of transition to proofs in open geometric situations.
In this paper I will present some findings of a teaching experiment on proof. Pupils were requested to produce conjectures in open geometric situations, to validate and, finally, to prove them. These activities took place in the microworld Cabri-Géomètre Our project was aimed to investigate the validity of the Cabri software as a mediator in the process discovering-conjecturing-proving. We found out that different dragging modalities are crucial for producing a shift from conjecturing to provi
Problem-solving and Web resources at tertiary level
We organised two experimental teaching designs involving web resources in two different French universities. In this paper, we describe these experiments and analyse the students' behaviours. Our aim is to observe whether the use of specific online resources favours the development of problem-solving activities.
Students' and teachers' perceptions of motivation and learning through the use in schools of multime
This article is the result of interviews with teachers, students, and school librarians in eight UK secondary schools regarding their use of multimedia encyclopaedias on CD-ROM. It focuses on a content analysis of their comments on how having access to multimedia encyclopaedias changes the way students work and learn in school, how they perceive it enhances their learning, and how it hinders it. Teachers reported that they used multimedia encyclopaedias as an additional information resource, or
Constructing structure in number sequences
This paper reports on a design experiment in the domain of number sequences conducted in the course of the WebLabs project1. In this study, we designed and tested a set of activities in which 13-14 year old students use the ToonTalk programming environment to construct models of sequences and series, and then use the WebReports web-based collaboration system to share these models and their observations about them. We utilise a design pattern (programming method) called "Streams" which enables st
Taking Programming into Kindergartens: Exploratory Research Activities Using ToonTalk
We believe that computers should be introduced in kindergarten education under the same philosophy and methods employed for other elements of modern society. Children should be familiar with computers in general, not just with specific sets of skills. We see computer programming in particular as a way to empower children, allowing them to grasp fundamental computing concepts, and not fearing to use a computer in novel ways; they should be able to approach the computer-tool as an adaptable tool,
ToonTalk in Kindergartens: Field Notes
The emergence of a fully graphical, animated programming language, such as ToonTalk, prompted the question: is computer programming a viable educational activity with kindergarten-aged children? Since May 2000, we have been conducting ToonTalk sessions with 3- to 5-year old children, trying to determine what approaches are more successful, what activities are viable, what issues may arise in the process. From November 2001 to February 2002, the sessions took place regularly in a normal kindergar
Industrial Districts and Innovation Business Networks: New Theories and Concepts for Entrepreneurshi
Over recent years, the study of industrial districts, inter-organizational relations and networks has become a major theme of interest in entrepreneurship research. Theories point to a new form of entrepreneurship and firm development which is based on the idea of creating links between firms to increase their chances of success and development. In this paper, we will present some data from a research we have conducted in Canada, in the province of Quebec to be exact, but first, we will present
