Sharing solutions: persistence and grounding in multi-modal collaborative problem solving
This article reports on an exploratory study of the relationship between grounding and problem solving in multimodal computer-mediated collaboration. This article examines two different media, a shared whiteboard and a MOO environment that includes a text chat facility. A study was done on how the acknowledgment rate (how often partners give feedback of having perceived, understood, and accepted partner's contributions) varies according to the media and the content of interactions. It was expect

Mechanisms of common ground in case-based web-discussions in teacher education
Previous studies suggest that before the participants in Web-based conferencing can reach deeper level interaction and learning, they have to gain an adequate level of common ground in terms of shared mutual understanding, knowledge, beliefs, assumptions, and presuppositions (Clark & Schaefer, 1989; Dillenbourg, 1999). In this paper, the main purpose is to explore how participants establish and maintain common ground in order to reach deeper level interaction in case-based Web-discussions. The s

New Media and Open and Distance Learning: New challenges for Education in a Knowledge Society
The "digital society" provides not only with new technology, but also with new concepts. Information plays a central role and becomes a valuable good, but knowledge cannot be reduced to information, and one aim for educators is to contribute in a "knowledge society", not only an "information society". A knowledge society is structured in networks, enriching the traditional hierarchies; a knowledge society promotes a kind of "collective intelligence". In such a society, open and distance learning

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… But for the

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.

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

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.

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 user’s 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

The evolution of research on collaborative learning
For many years, theories of collaborative learning tended to focus on how individuals function in a group. More recently, the focus has shifted so that the group itself has become the unit of analysis. In terms of empirical research, the initial goal was to establish whether and under what circumstances collaborative learning was more effective than learning alone. Researchers controlled several independent variables (size of the group, composition of the group, nature of the task, communication

A walk on the WILD side How wireless handhelds may change computer-supported collaborative learning
Designs for CSCL (Computer-Supported Collaborative Learning) applications usually presume a desktop or laptop computer. Yet future classrooms arc likely to be organized around Wireless Internet Learning Devices (WILD) that resemble graphing calculators, Palm, or Pocket-PC handhelds, connected by short-range wireless networking. WILD learning will have physical affordances that are different from today's computer lab, and different from classrooms with 5 students per computer. These differing aff

Learning Design and Run-Time Resource Binding in a Distributed e-Learning Environment
Nowadays, the need for e-learning systems supporting a rich set of pedagogical requirements has been identified as an important issue in the field of distance learning. Several initiatives take place in order to meet this need. Maybe, the most important of these initiatives is IMS Learning Design [6] that provides a framework to depict pedagogies. Furthermore, we are aware that the provision of different learning paths tailored on learner's characteristics and preferences guarantees the learner

The aim of bringing semantics to learning content and services is to enable large scale collaboration of e-learning activities over the Grid infrastructure. As machines and software applications will be ubiquitously involved in enabling and facilitating this collaboration, it requires a common understanding of the domain, in particular at the conceptual level, so that both computers and human participants of the e-learning activities understand and are able to communicate among themselves thoug

A bootstrapping scenario for elicitating CSCL services within a GRID virtual community
Amongst the various eLearning techniques, Computer Supported Collaborative Learning (CSCL) is of growing interest within the academic world. However, during the first phase of the EleGI project, a noticable fact has been the difficulty to match the user needs with the potentiality of the GRID services. Thus, through a fictive scenario, this article proposes to walk the path between the idea of creating a new virtual community and the realisation of this objective. This scenario takes the situat
