Automatically generated exercise pages
In order to generate an exercise page on a particular knowledge, exercises have to be indexed according to the knowledge useful to solve them. Hence, the main idea of this project is to use a problem solver, Argos, to help us deal with this indexation. Argos aims not only at solving geometry problems, but also writes their proofs just as a teacher or a pupil would. Consequently, the meaningful data have to be extracted from the proofs found by the solver. Argos automatically generates rules from
Designer integration in training cycles : IEEE LTSA model adaptation
This paper describes an architecture centered on a component model for the course cycle. This model guides a re-engineering process based on the observed use scenarii. It is applied in an institutional framework and uses learning devices provided by the open source community. The architecture integrates the latest works on learning technology standards.
Vers une approche déclarative pour les logiciels de dessins géométriques
Cet article est consacré à la conception d'un environnement d'apprentissage de la géométrie orienté vers la manipulation directe de figures géométriques. À travers deux exemples d'activités, proposées en classe, on distingue les notions de construction géométriques, de spécification, et de manipulation directe. Dans le cadre ainsi défini, nous présentons notre approche. Elle consiste à intégrer des mécanismes et la méthodologie de l'intelligence artificielle dans un logic
Are well-designed Web sites efficient for learning mathematics at the undergraduate level?
We conducted an experiment in order to examine the effectiveness of an educational Web site, which provides resources to undergraduate students in mathematics. The participants' task was to solve 18 questions about differential equations. Students in the paper condition outperformed those in Web site conditions. There was no difference between the original and an improved Web site version. Moreover, students in all conditions preferred working with the paper resource. Practical and theoretical i
Two Years Of Use Of The Aplusix System
APLUSIX is a learning environment for helping students to learn algebra. This system is designed and developed in the IMAG-Leibniz laboratory. Its basic training mode consists of letting the students perform their owns calculations, thanks to a two-dimensions editor of algebraic expressions, providing feedback on the correctness of the calculations and on the end of the resolution. APLUSIX has now been used for two years at school, in different contexts. One use was made by four teachers during
Tutorial planning : Adapting course generation to todays needs.
Most of today's course generation does not allow an in-depth, generic representation of pedagogical knowledge. However, supporting individual learners with different goals requires an elaborate representation of pedagogical expertise. In this paper, I describe a framework that adapts existing approaches for representing and using pedagogical knowledge to meet today's needs. Furthermore, I will show how in this framework several of today's problems are solved, such as the integration of distribut
Learning Design Engines as Remote Control to Learning Support Environments.
Context: Chapter 5 of the Learning Design book describes the operational model of a learning design engine based on the concept of finite automata with output alphabet. We rely on this event concept to include pre-existing learning tools in flexibe and rich learning designs. Contribution: We sketch an approach for the integration of complex learning environments in learning designs. Interactive learning support environments, such as argumentation or modelling tools are pre-existent and have a hi
Quantitative and Qualitative Research: Conflicting Paradigms or Perfect Partners?
This paper will examine the use of quantitative and qualitative methods as complementary research methods. It asks the fundamental question wether these two approaches can be used jointly in a principled manner. The pressure in educational research has been towards using the two methods alongside each other. In applied research the use of the two approaches in the same project is accepted yet we still find serious objections raised to such work when it is presented in a more formal context. Eval
TéléCabri, un environnement pour le préceptorat à distance.
L'objectif du projet TéléCabri est de contribuer à la solution de ces problèmes en apportant des moyens complémentaires de l'action humaine pour assurer la continuité de la scolarité pendant l'hospitalisation des enfants ou adolescents. TéléCabri doit apparaître comme une machine partenaire de l'élève autant que de l'enseignant. En intégrant la téléprésence et des fonctionnalités de coopération dans un environnement informatique pour l'apprentissage humain.
Internal and external cooperation scripts in web-based collaborative inquiry learning
Cooperation scripts are a powerful means to improve collaborative learning. Scripts can be designed to support argumentative knowledge construction. However, not only externally induced cooperation scripts but also the learners internal scripts on argumentative knowledge construction influence argumentative processes and what kind of knowledge is acquired during collaboration. In this study, 98 students (49 dyads) of two German secondary schools participated. We implemented two versions (high
The role of roles in the analysis of interactions in collaborative environments
Analysis of interactions has become a basic function in the field of collaborative learning, as a means for supporting both students' self-regulation as well as formative evaluation processes. However, we observe a lack of methods and tools for the analysis of interactions in CSCL that considerer the different roles implied in collaboration management processes, both from the point of view of the actors that take part in a typical CSCL scenario: teachers, students or the system
Understanding and analysing activity and learning in virtual communities
The purpose of this study is to provide a preliminary framework to observe, analyse and evaluate both activity and learning in virtual communities. So various types of virtual communities will be studied by examining their relationship to socialisation and learning. After a presentation of the main ideas of Wenger’s social learning theory, the principal components of the social context of the emergence and evolution of virtual communities will be described. It will show how taking this context
A Metadata Based Web Distance Learning Platform
Distance Learning is acquiring a role that becomes more and more important with the huge diffusion of the Internet and related technologies. Consequently, the investigation for adequate architectures and platforms supporting flexible Distance Le arning engines and solution is nowadays of great interests in the Scientific Community. The present paper introduces a platform based on the adoption of Metadata concepts and on the use of a “processorlike” behavior of the Web Course Delivery engine
Applying Competence Structures for Peer Tutor Recommendations in CSCL Environments.
Competence structures of the content and competence modelling of the learners provide well-suitable means for finding appropriate peer tutors in CSCL based on asynchronous messaging and annotations. Various criteria for the appropriateness of potential peer tutors can be discussed. An internet-based system used as a large scale Web experiment can then also deliver data for evaluating such criteria.
EMLs : case study in distance learning education
After a short characterization of what an educational modeling language should be, we will deal with the respective interest of two EML proposals : one proposed by OUNL (OUNL/EML and IMS/LD which is derived from it) and one proposed by UNED (PALO). We will then identify reasons that lead us to choose OUNL/EML for experimentation in distance learning education in order to model our scenario. Finally we will present some limitations or extensions we have identified.
Organisational patterns for e-learning centres
In this paper we explore the notion of using organisational patterns in educational design for the development of e-learning centres. We are using patterns to discuss some of the key aspects concerning the implementation of an e-learning centre within an institution, with an emphasis on the purposes and pedagogical principles that will help to successfully support such an initiative. The research approach which informed our pattern development work includes use of a qualitative survey of a set o
