The co-design of scenarios for a didactic-based E-learning system viewed as an adaptive virtual docu
The design and engineering of E-learning systems must be considered as a transdisciplinary problem requiring the integration of different scientific approaches. The design process of E-learning systems needs to consider several theories, models and artifacts – the e-learning system. We claim it is essential to ensure the traceability and the interpretation of phenomena related to the use of artifacts in studying precisely the relationships between theories, models and artifacts. Consequently, w
Designing and evaluating collaboration in a virtual game environment for vocational learning
Especially in vocational education, attention should be paid not only to the use of new technological solutions but also to collaborative learning and cooperative working methods in order to develop studentsÂ’ skills for their future jobs. This study involves a design experiment including the design process of a new game environment, description of the script developed for this game, as well as the empirical study with multiple data collection methods, data analysis, results and conclusions for
Supporting Peer Help and Collaboration in Distributed Workplace Environments
Increasingly, organizations are geographically distributed with activities coordinated and integrated through the use of information technology. Such organizations face constant change and the corresponding need for continual learning and renewal of their workers. In this paper we describe a prototype system called PHelpS (Peer Help System) that facilitates workers in carrying out such "life long learning". PHelpS supports workers as they perform their tasks, offers assistance in finding peer he
Détermination automatique des théorèmes-en-acte des élèves en algèbre. Le cas des équations e
Dans cet article, nous sommes intéressés à la détermination automatique de théorèmes-en-acte en algèbre. Ces théorèmes-en-acte ont été construits de façon abstraite, puis nous avons cherché à automatiser le mécanisme de leur diagnostic. Pour cela, nous avons utilisé le logiciel Aplusix comme support des productions des élèves qui permet d'enregistrer toutes les actions des élèves. Une base de règles correctes et erronées a été mise en place et un interpréteur de règles
Didactique et intelligence artificielle
Le présent article reprend l'essentiel du contenu de mon exposé introductif à la journée
"Didactique et environnements d'apprentissage informatisés" de la VI° école d'été de didactique des mathématiques (Gras 1991) et les principales idées présentées lors du premier exposé que j'ai fait sur ce thème à l'occasion des XIII° journées francophones sur l'informatique (Balacheff 1991). Il s'agit de suggérer des lignes de recherches potentiellement fécondes pour les didacticiens, da

Children's mental models of recursive logo programs
Children who had a year of Logo programming experience were asked to think-aloud about what brief Logo recursive programs will do, and then to predict with a hand-simulation of the programs what the Logo graphics turtle will draw when the program is executed. If discrepancies arose in this last phase, children were asked to explain them. A prevaient but misguided "looping" interpretation of Logo recursion was identified, and this robust mental model persisted even in the face of contradiction be
Learning Objects 2: Standards, Metadata, Repositories, and LCMS
This book is the second in a four-volume series. It builds upon the first volume by taking an extended and in-depth look at theorists' and practitioners' efforts to consolidate current knowledge and praxis. This consolidation centers around conceptual and technological issues related to standards, metadata, repositories, and the concept of the LCMS (Learning Content Management System). Part I contains six chapters that focus upon LO concepts vis-Ã -vis architecture. A discussion of syntax, seman
Negotiation of Spatial Configurations in Collaborative Virtual Environments
In the last decades a new culture of childhood has been emerging that redefines the relations between children and their social environment. Instead of seeing children as passive actors in the society where they live, children are regarded as social actors capable of supplying their own personal and active contribution to social life. This approach includes involving children in the planning of physical spaces as well as in social and cultural interventions in their society.

Technical Infrastructure: The WebReports site
The WebReports website allows children to create text-based and interactive content that is accessible on line and to comment on each otherÂ’s work, thereby being provided with opportunities to collaboratively build knowledge around a range of different learning domains. In this document we first summarise our key findings. We then provide an account of the evolution of the system during the three years of the project, giving the rationale for our major changes. Finally, we describe the function
Exploring the mathematics of motion through construction and collaboration.
In this paper we give a detailed account of the design principles and construction of activities designed for learning about the relationships between position, velocity and acceleration, and corresponding kinematics graphs. Our approach is model-based, that is, it focuses attention on the idea that students constructed their own models – in the form of programs – to formalise and thus extend their existing knowledge. In these activities, students controlled the movement of objects in a prog
Student's modelling with a lattice of conceptions in the domain of linear equations and inequations
We present a student's modelling process in algebra which consists of two phases. The first phase is a local diagnosis where a student's transformation of an expression A into an expression B is diagnosed with a sequence of rewriting rules. A library of correct and incorrect rules has been built for that purpose. The second phase uses a lattice of conceptions built for modelling students more globally. Conceptions are attributed to students according to a mechanism using the local diagnoses as i

7.1 Hierarchies of ideas
Diagrams, mind-maps, tables, graphs, time lines, flow charts, sequence diagrams, decision trees: all can be used to organise thought. This unit will introduce you to a variety of thinking skills. Asking and answering questions is at the heart of high-quality thinking. Questions naturally arise from the desire to know and learn about things and may be the starting point for a journey of understanding.
12 Further reading and sources of help
Writing reports and assignments can be a daunting prospect. This unit is designed to help you develop the skills you need to write effectively for academic purposes. You will learn how to interpret questions and how to plan, structure and write your assignment or report.
