This reference work explores the concept of open learning, interpreting it as the provision of an environment and learning opportunities which cause effective learning to take place. This edition has been revised and updated to examine the design of flexible learning resource materials, to be used within traditional training programmes. New methods used for flexible learning - interactive videos, CDs, audio and tape support - are described in detail. There is also an extensive glossary of open learning terminology, plus workshop formats and exercises designed for the developers and tutors of open learning courses.
