In this work we propose an ontology-based model for the formal specification of the relations which have been used for the representation of a cognitive domain. This ontology has been used for the representation of the educational material developed for Hellenic Open University (HOU). },

The importance of a distance learning program heavily depends on the type and quality of the provided digital content. The Hellenic Open University (HOU) offers distance learning courses and therefore the volume of the provided digital learning content is significantly large. This fact establishes essential the need for an efficient and effective mechanism for searching, managing and retrieving the educational content. A modern approach for the organization of the digital learning material is the Learning Objects (LOs) paradigm, the use of which is adopted by many e-learning systems and applications nowadays. In this work we try to take advantage of all of the good characteristics of LOs and propose an instructional design methodology that builds courses based on these particular chunks of educational material. The aim of the proposed methodology is exactly to provide guidelines for the design and creation of courses based on LOs. Secondly, it intends to exploit semantic technologies in order to capture and represent the knowledge that is produced during each step. This semantically enriched information, regarding a course, is could be ideally utilized during the creation of LOs.

Educational content plays a significant role in the process of delivering knowledge, thattextquoterights why it needs to be designed carefully, following designated principles. Learning Objects (LOs) constitute a novel approach in the educational contenttextquoterights organization, bearing features that if effectively used could lead to enhanced e-learning services. What is missing from literature, though, is a common agreement about the LOtextquoterights attributes and structure. For this reason, we initially try to specify the main characteristics of a LO and determine its functionality, especially in the context of distance education. Having realized its fundamental role in the instructional design process, we make explicit its correlation with educational objectives and other aspects of learning. Finally, in an attempt to capture all LOtextquoterights characteristics and make them utilizable by e-learning applications, we propose a metadata schema, reflecting all features of a LO, as described in this work.

abstract = {According to the definition of a portfolio as an organised collection of materials that presents and verifies skills and knowledge acquired through experience it is of particular relevance to validating non-formal and informal learning because it allows the individual to contribute actively to the collection of evidence and also offers a mix of approaches strengthening the overall validity of the process. An eportfolio additionally offers increased capacity to accumulate data that can provide the audience with greater insights into the achievements and successes of the learner.
The eportfolio presenting in this paper is the product of the VAB (VAluing experience Beyond university) project. The VAB project aimed at proposing an eportfolio as a pedagogical tool that along with an e-training would allow University teachers to take into account any competences acquired via non-formal/formal learning outside university, in order to assess their students. The VAB project via the eportfolio developed enables teachers to value the personal, social and professional experience of their students acquired beyond the University in order to enhance their professional integration. The main issue of the VAB project was to bridge the gap between University and the labour market by proposing a pass between theoretical/practical learning and professional skills and competences required by the labour market through a pedagogical tool proposed to University teachers/trainers.This paper presents the VAB web based ePortfolio platform, basic elements of its structure, an example of its usage, the main outcomes of the evaluation procedure as well as topics for future consideration that have arisen during the project.},
