Distance education: A particular context for teaching and learning. Introduction to this special issue

This editorial introduction positions distance education in the larger context of educational research and theory construction. Next to a definition of key concepts, the authors elaborate three major issues that are dealt with in distance education research in relation to educational materials. The first issue centres on curriculum and values. The second topic concentrates on the creation of appropriate learning environments. The third issue focuses on the evaluation of effects of materials in use. In discussing the three issues the authors stress the particularities of the distance education context.
