A User-Friendly Sign Language Chat
The introduced concept of a gesture based sign language chat enables the communication of hearing impaired people over networks, including concerns regarding low throughput and bandwidth characteristics. Existing applications handle that task not appropriate, since either high bandwidth networks are necessary or the extensibility of the vocabulary is complicated for untrained users. Thereby our approach facilitates existing image recognition techniques for the determination of gestures which are

The use of a computerized brain atlas to support knowledge-based training in radiology
Trainers of radiologists face the particular challenges of teaching normal and abnormal appearance for a variety of imaging modalities, providing access to a large appropriately-indexed case library, and teaching a consistent approach to the reporting of cases. The computer has the potential to address these issues, to supplement conventional teaching of radiology by providing case-based tutoring and diagnostic support based on a large library of images of normal and abnormal anatomy, fully desc
Task and Interaction Regulation in Controlling a Traffic Simulation
In collaborative problem solving, metacognition not only covers strategic reasoning related to the task but also reasoning related to the interaction itself. The hypothesis underlying this work states that regulation of the interaction and regulation of the task are closely related mechanisms and that their co-occurrence facilitates collaborative problem solving. These assumptions are tested experimentally with a traffic simulator. The results show that co-occurrence of task and interaction regu
Learning to collaborate: Designing collaboration in a 3-D game environment
To respond to learning needs, Computer-Supported Collaborative Learning (CSCL) must provide instructional support. The particular focus of this paper is on designing collaboration in a 3-D virtual game environment intended to make learning more effective by promoting student opportunities for interaction. The empirical experiment eScape, which encourages learners to solve problems collaboratively, is also presented. eScape is a design experiment, comprising both the process of designing a collab
An approach to distance learning curriculum appropriation
The work presented aims at supporting distance learning students in their appropriation of a curriculum. We propose an approach that consists in helping students to construct individual projects. We dissociate different aspects (planning, evaluation and regulation) that can be useful for this purpose, propose a technological approach (epiphyte system, ontology-based model) and example of tools currently provided by the Saafir framework.
Regulative support during inquiry learning with
simulations and modeling
Many factors impact learning; the environment and resources available, the domain, how much prior-knowledge a student has, and how well they make use of their metacognitive skills, all of these factors impact new knowledge creation. The series of studies described in this dissertation focuses on the latter; i.e. the metacognitive skillfulness of students. Known collectively as self-regulation, planning, monitoring, and evaluation, when applied appropriately will enhance learning. Students who m
Open Distance Inter-University Synergies Between Europe, Africa and the Middle East (ODISEAME)
The challenge facing new technologies is whether they can contribute to a qualitative step up and to education for all as a process of facilitating the development of creative people with the ability to think critically and to engage in socially relevant decision making. In this paper, we describe a project whose purpose is to develop a learning environment that takes into account current expertise in learning theory in order to facilitate productive collaboration in a way that leads to active c
Designing biases that augment socio-cognitive interactions
This chapter questions the assumption that the best environment for computer-supported collaborative learning is the one that most closely reproduces the features of face-to-face collaboration. Empirical studies have failed to establish the superiority of group interaction with richer media. Instead, the chapter explores media features that do not exist in face-to-face interactions and explains how these features might augment group cognition. The first feature, the persistency of the informatio
Shared conceptualisations in weblogs
In this paper we investigate how conceptualisations can be identified in weblogs using language technology (automated text analysis). We focus on getting a handle on both the concepts bloggers use and the way they think these concepts are related. The analysis of these conceptualisations can then be applied to a single weblog, resulting in a visualisation of potential conceptualisations the blogger wants to share with the outside world. Another type of analysis is to determine the overlap, or sh
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

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
Reactive Learning Objects for Distributed e-Learning Environments
We present a concept of reactive learning objects that goes away from the hydraulic view of e-learning and gives to students activity a central place. First experimentations suggest that this concept should be enlarged to include distributed computation, distributed storage and Web services.
The Semantic Aspects of e-Learning: Using the Knowledge Life Cycle to Manage Semantics for Grid and
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
