Training strategies and knowledge acquisition: Using the same reflective tools for different purpose
The Emma educational system embodies a Knowledge Based System (KBS) that models a problem-solving method defined at an abstract level. In order to allow different explicit problem-solvings, the KBS is based on a Task-Method modelisation. The objectives of this paper are (1) to explain how we take advantage of the flexibility provided by the modelisation by using analysis-modules that can study what the influence of the student's propositions on the rest of the solving is; (2) to highlight that e

Enhancing a Web-Based Distance-Learning Curriculum with Dedicated Tools
The work presented in this paper aims at supporting students involved in a Web-based distance-learning curriculum. For such a purpose, the Saafir system proposes students with different tools that support them in their appropriation of this curriculum, e.g. visualization of the curriculum from different points of view or construction of individual projects by putting different items of the curriculum into relation. In order to allow using Saafir with already existing distance-learning Websites,

Cowos: A Model of Collective Work Situations to Support Modelling and Simulation Based Approaches of
This paper describes an operational model of collective work situations. This model is rooted in the CHAT theory. It allows creating multi-agent simulations where the agents’ behaviour is defined in terms that make salient organization issues, and allows building learning situations that focus on making students consider explicitly these issues.

Structural Awareness for Collaborative Learning Environments
In this paper we propose a peer-to-peer support approach that we call structural awareness support. The structural awareness aims to support the communication that takes place in virtual learning communities. Its emphasis is on revealing the group structure to its participants in order to promote collaborative interactions. This support has been implemented on a forum type tool called Mailgroup. It has been tested twice in different contexts, obtaining initial feedback of its pertinence accordin

Implementation of a computer algebra based assessment system
This article describes the design and implementation of the CABLE computer aided assessment system. Introducing a computer algebra system (CAS) to assist in marking allows instructors to design effective assessment schemes that are valid and reliable. A modular design approach allows system components, including a virtual learning environment (VLE), CAS and database, to be used for their respective strengths. Requirements for both interoperability and customisation for particular learning contex

Using mobile technologies for multimedia tours in a traditional museum setting
Mobile technology was used to deliver learner-centred experiences to visitors at a geology museum without compromising the museum’s aesthetic appeal. Two Flash-based multimedia tours were developed for the Hypertag Magus Guide system and trialled with 25 visitors in November 2005. Trial participants found the system fun and easy to use, though they requested headphones in order to hear the audio clearly. Several suggestions were provided to improve the tours including creating stronger links b

Balancing situativity and formality: the importance of relating a formal language to interactive gra
A situated cognition theory is presented in which situated learning is viewed from a Vygotskian perspective: the developmental situativity theory. It is assumed that learning is basically a non-symbolic inductive process that is greatly enhanced by formal systems which act as tools. Instruction should provide students with an environment containing elements to allow for situated activity as well as with appropriate formal tools.

Cognitive processes in solving variants of computer-based problems used in logic teaching
The effect of two instructional variables, visualisation and manipulation of objects, in learning to use the logical connective, conditional, was investigated. Instructions for 66 first-year social science students were varied in the computer-based learning environment Tarski's World, designed for teaching first-order logic (Barwise & Etchemendy, 1992.

The impact of example comparisons on schema acquisition: Do learners really need multiple examples?
Comparing multiple examples within problem categories is usually considered a necessary prerequisite for schema acquisition. However, there is an evident lack of conclusive empirical evidence supporting this claim. Moreover, there are findings indicating that carefully designed one-example conditions may allow for profitable processes of example comparison as well. In line with this reasoning, we present an experiment - that builds up on a series of studies conducted by Quilici and Mayer (1996)

Using e-mail to support reflective narration
This article presents an exploratory study of e-mail use for reflective narration. Narration is viewed from three perspectives: the narrating act, the narrative statement, and the story. These perspectives are used to characterize the 69 e-mails that were exchanged between 13 groups of children from three primary schools. The findings show that e-mail narration has monologic and dialogic qualities, and leads to cognitive and personal reflections on the learning task. We conclude that e-mail can

Gridcole: a tailorable grid service based system that supports scripted collaborative learning
This paper introduces Gridcole, a new system that can be easily tailored by educators in order to support the realization of scripted collaborative learning situations. To do so, educators can provide a script specifying the sequence of activities to be performed by learners as well as the tools and documents required to support them. Gridcole can then search for these tools in a service-oriented grid in order to integrate them so that they are available for users during the realization of the s

Researching classroom interactions: A methodology for teachers and researchers
Teaching and learning in schools is a complex social process which involves both the teacher and students in distributed knowledge-building activities. Research into this process includes researchers exploring from the outside and teachers exploring from the inside (Bassey, 1995). Jaworski (2003) draws on the work of Wagner (1997) to elaborate a form of research which she calls co-learning, in which research on classroom learning is “conducted jointly by outsiders and insiders” (p 250).

Embedded Training for Complex Information Systems
One approach to providing affordable operator training in the workplace is to augment applications with intelligent embedded training systems (ETS). Intelligent embedded training is highly interactive: trainees practice realistic problem-solving tasks on the prime application with guidance and feedback from the training system. This article makes three contributions to the theory and technology of ETS design. First, we describe a framework based on Normanâs "stages of user activity" model for d

A Framework for Assessing Self, Peer and Group Performance in e-Learning
In this chapter we propose a framework that supports the analysis and assessment of collaborative learning of online groups of students working on a complex task (software project, or case study) in a real web-based, distance learning context. On the one hand, our approach is based on principled evaluation criteria that involve and measure a variety of elements and factors as well as on a combination of a basic qualitative process and a quantitative method that provide a grounded and holistic fr

Decentralized Service Deployment for Collaborative Environments
In this paper we present the design of a system which allows service deployment in a small-sized group of computers distributed through the Internet. These groups are formed by users who share a common interest, and voluntarily yield their own resources for the achievement of the collaborative activities of the group. Having enough resources contributed by the members of the group, our system guarantees service availability and the fact that the deployment and execution of the services is carrie

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

Extending the Scope of Asynchronous Collaboration: a Matter of Being Autonomous and Self-sufficient
Asynchronous collaborative applications and systems have to deal with complexities associated with interaction nature, idiosyncrasy of groups and technical and administrative issues. Inclusion of requirements derived from them is costly (in time, resources and economically). Existing solutions addresses asynchronous collaboration via simplification of requirements and by using centralized models. In this paper we present LaCOLLA, a fully decentralized infrastructure for building collaborative ap
