The document discusses the theoretical framework for distance education proposed by Desmond Keegan, which asks whether distance education is an educational or business activity, if it is conventional, and if the terminology is possible. Keegan's framework considers the relationship between time and location in distance education and identifies 5 changes it brings to the normal structure of education, including the industrialization of teaching, privatization of instructional learning, and different cost structures. It also notes that technology has changed general education theory and made what was once impossible now possible.
