The paper aims at developing a model for a Virtual Environment for Distance Education and Training (VEDET) that offers a comprehensive metaphor to be used both for humancomputer interface and instructional design purposes. It also gives a paradigm for restructuring traditional education and training by complementing them with a virtual component. Thus the VEDET would not replace the traditional school, university or training department of a organisation but rather extend their facilities and tools and make their activities more flexible and technologically enriched.
