It is characteristic that, while AVD communication technology is considered mature, it has not yet been widely integrated into educational settings at a large scale. An important reason for this apparent failure is the lack of expertise on behalf of teaching and supporting technical staff regarding the capabilities of the equipment itself as well as access to good practices on the integration of the equipment into pedagogical methodologies taking into account underlying infrastructure constraints. The Audio-Video and Data (AVD) knowledge base constitutes a new independent European framework for disseminating and deploying pedagogical use of high quality real time audio, video and data communication and collaboration services into distance learning environments. It will be completed in 2006. The AVD information base solution will offer improved learning experiences, technical advice based on expert knowledge, good practice based on collective end-user knowledge, train-the-trainer program for teaching personnel, and model recommendations for the wide adoption and effective integration of visual communication into distance training programs. This paper presents the system design of an AVD-knowledge base aiming at the dissemination of pedagogical and technical expertise related to the integration of AV-technology and pedagogical methodologies offering improved learning experience to students. The proposed system aims at the creation and fostering of a community for the sharing of information that originates both from experts and peers publishing their experiences.
