A Model for the Efficient Representation and Management of Online Collaborative Learning Interaction
This study aims to explore the importance of the efficient representation and management of the event information generated from group activity in online collaborative learning practices so that we can use it to provide awareness about individual and group behaviour. The achievement of this goal first involves the design of a conceptual model of collaborative learning interaction that structures and classifies the information generated in an online collaborative learning situation at several lev
Gridifying IBM's Generic Log Adapter to Speed-Up the Processing of Log Data
Problem determination in today's computing environments consumes between 30 and 70% of an organizations IT resources and represents from one third to one half of their total cost of ownership. The first step to cutting down costs in this area and to enable autonomic computing systems is to have all parts of the system report status in a common log data format and semantics in order to be able to exploit the status information of the system as a whole. The Generic Log Adapter (GLA) is a generic
Semantic Description of Grid Based Learning Services
Grid technology has emerged as a powerful tool to increase the
capabilities of e-learning frameworks. Learning services are fundamental
components representing functionalities that can be easily reused without
knowing the details of how services have been implemented. On the one hand, a
problem that still remains unsolved is how to use and integrate low-level
learning services to compose more complex high-level services or tools that
make sense to both tutors and learners. On the other hand, the
Towards educational data mining: Using data mining methods for automated chat analysis to understand
In this paper we investigate the application of data mining methods to provide learners with real-time adaptive feedback on the nature and patterns of their on-line communication while learning collaboratively.We derived two models
for classifying chat messages using data mining techniques and tested these on an actual data set [16]. The reliability of the classification of chat messages is established by comparing the models performance to that of humans. Results indicate that the classificatio
Training programme for geography teachers
This paper contains a description of a Geography teacher-training program for in-service education. The program is a variant for incorporating the methodology of the Minerva- project Innovative Didactics via Web-based Learning (further abbreviated as IDWBL) so that the Geography teachers at work can be adequately prepared for integrating ICT in geography education at secondary schools via web-based education. The theme may seem at first glance as a variation of a known subject

E-learning environments in medical education: how pervasive computing can influence the educational
As pervasive computing is integrated incrementally with all facets of everyday life, it is reasonable to expect that its further proliferation may influence educational activities as well. Several such arguments have been thoroughly discussed in literature and several projects have been developed. However, little work has been done to investigate how pervasive computing can influence the medical educational process using e-learning platforms, and the prerequisites for such endeavours. In this pi
I*teach methodology in school practice
One of the assumptions of secondary education is that students are to acquire numerous ICT-related skills. The computer has become an essential element of live, both at school and outside it. Using ICT tools students can structure their knowledge, prepare images, create banks of data and analyze it, write reports and other text documents. Electronic mail, discussion lists, forums and other online applications facilitate communication and cooperation. World Wide Web gives an easy access to immens
Aspects of Speech Act Categorisation: Towards Generating Teachers' Language
In this paper we examine a possible method for classifying speech acts produced by human teachers, with a view of informing the designs of intelligent natural language tutors and of providing the basis for a formal analysis of the effects that teachers' language has on students' learning. We argue that traditional means as initiated by the Ordinary Language Philosophers such as Austin (1962), Grice (1975) and Searle (1979) are not sufficient to account for all types of linguistic phenomena occur
Supporting Social Interaction in an Intelligent Collaborative Learning System
Students learning effectively in groups encourage each other to ask questions, explain and justify their opinions, articulate their reasoning, and elaborate and reflect upon their knowledge. The benefits of collaborative learning, however, are only achieved by active, well-functioning teams. This paper presents a model of collaborative learning designed to help an intelligent collaborative learning system identify and target group interaction problem areas. The model describes potential indicato
Methodological Issues in the Content Analysis of Computer Conference Transcripts
This paper discusses the potential and the methodological challenges of analyzing computer conference transcripts using quantitative content analysis. The paper is divided into six sections, which discuss: criteria for content analysis, research designs, types of content, units of analysis, ethical issues, and software to aid analysis. The discussion is supported with a survey of 19 commonly referenced studies published during the last decade. The paper is designed to assist researchers in using
STyLE-OLM: Interactive Open Learner Modelling
here is a strong argument in Artificial Intelligence in Education which advocates that computer-based learning systems need to adapt to the needs of learners if they are to provide for effective personalised instruction (Self, 1999a). Diagnosing a learner's cognitive capacity is a crucial issue in building adaptive systems. We have explored an interactive open learner modelling (IOLM) approach which conceives diagnosis as an interactive process involving both a computer system and a learner that
An Intelligent Tutoring System for Entity Relationship Modelling
The paper presents KERMIT, a Knowledge-based Entity Relationship Modelling Intelligent Tutor. KERMIT is a problem-solving environment for the university-level students, in which they can practise conceptual database design using the Entity-Relationship data model. KERMIT uses Constraint-Based Modelling (CBM) to model the domain knowledge and generate student models. We have used CBM previously in tutors that teach SQL and English punctuation rules. The research presented in this paper is signifi
The ZAP Project: Designing interactive computer tools for learning psychology
In the ZAP project, a set of interactive computer programs called 'ZAPs' was developed. The programs were designed in such a way that first-year students experience psychological phenomena in a vivid and self-explanatory way. Students can either take the role of participant in a psychological experiment, they can experience phenomena themselves, or they can take the role of researcher and learn by discovery. ZAPs provide added value to existing learning materials about psychological topics and c
Éditorial du numéro spécial "Les ontologies pour les EIAH"
Lingénierie ontologique est devenue depuis peu une composante incontournable des sciences cognitives. Dans un tel contexte, la communauté EIAH dont lobjet final est le partage et la transmission de la connaissance ne pouvait être en reste. Ainsi, lontologie et lingénierie ontologique sont des termes qui commencent à apparaître régulièrement dans les communications scientifiques de notre communauté [Crampes00] [RanwezCrampes01] [Psyché03] [Hibou03]. Lintérêt est croissant ch
Le rôle de lingénierie ontologique dans le domaine des EIAH
Dans cet entretien, Riichiro Mizoguchi nous révèle ses pensées les plus profondes sur le rôle que joue lIngénierie Ontologique (IO) dans le domaine des EIAH. Il insiste sur la nature conceptuelle dune ontologie, faite pour pouvoir partager des connaissances entre humains et ordinateurs, et entre ordinateurs. Conceptualisation, partage et réutilisation sont donc les concepts-clés dune ontologie. Dans le domaine des EIAH, le rôle de lIO nest pas de modéliser les connaissances po
Selecting Theories in an Ontology-Based ITS Authoring Environment
This paper introduces the rationale for concrete situations in the authoring process that can exploit a theory-aware Authoring Environment. It illustrates how Ontological Engineering (OE) can be instrumental in representing the declarative knowledge needed, and how an added value in terms of intelligence can be expected for both authoring and for learning environments.

Credibility of a simulation-based virtual laboratory: An exploratory study of learner judgments of v
Several studies have examined realism and instructional effectiveness of physical simulations. However, very few have touched on the question of their credibility or verisimilitude, from the users point of view. This article presents an empirical exploratory study which investigated the perceptions of potential users of a simulation-based virtual physics laboratory (the VPLab). In the VPLab, students conduct virtual physics experiments designed to promote both acquisition of general experiment
