Communication through artefacts, in the sense of objects (co-)constructed by learners, is a well known mechanism in synchronous shared workspace environments. In this article, we explore the potential of extending this principle to heterogeneous, anonymous and asynchronous learner communities by drawing on existing work, e.g. in the areas of " social(More)
The objective of the research presented in this article is to find representational mechanisms for relating and integrating the collaborative learning elements present in real practical environments, create an integrated ontology that considers and relates these elements, and make use of it to define new collaborative learning scenarios. It is therefore(More)
In this paper the underlying knowledge model and architecture of I-PETER (Intelligent Personalised English Tutoring EnviRonment) are presented. This system has been designed for the on-line distance learning of Eng-lish where too many students restrict the teacher's possibilities to provide indi-vidualised guidance. I-PETER is made up of four domain models(More)
This document presents an analysis of Music Knowledge as a first step towards music representation for composition. After an introductory review of music computing evolution, several approaches to music knowledge are described: the system levels context, music theory and disciplines, dimensions in music, and finally the creative process. Then, the(More)
In this paper the 'Active Document system', grounded in the Activity Theory, is presented. This system serves both as a representational framework for the description of learning activities and a harness for the mechanisms necessary to support the creation and management of the corresponding computer-based scenarios. This system is made up of three(More)
