This series is aimed at education professionals relatively new to distance education, with content just detailed enough for introductory use by and for trainers – whether educational, vocational or corporate. The expert-authored, ongoing series is a succinct, topic-by-topic overview of distance education theory and practice. With a reader-friendly approach, Knowledge Series titles are limited to six pages each, with print versions presented in a foldout format. Each title includes a bibliography and a further reading list.
