Cleveland-Innes, M. F., & Garrison, D. R. (Eds.). (2010). An introduction to distance education: Understanding teaching and learning in a new era (2nd ed.). New York, N.Y.: Routledge.
The impetus for revising the content for our book on Teaching and Learning in a New Era is that distance education is now a major player in the revision of education broadly. Higher education is facing multiple demands for change where distance education, as an alternative pedagogical and delivery approach, can be considered in the response to some of these demands. For example, distance education, appropriately designed and delivered, is the closest we can come to completing the iron triangle of education where all three elements of access, affordability, and quality can operate in tandem.
