ABSTRACT
A policy decision to introduce distance learning commits planners to the development of systems through which their plans can be implemented. This requirement applies whether the distance-learning initiative involves a new institution solely committed to distance learning, the provision of a programme for distant students within a conventional educational institution, or the introduction of training for employees of a company by correspondence or e-learning. In all these examples the separation of learners from teachers or facilitators requires mediation involving carefully structured and predictable processes.
