This document provides an overview of Athabasca University, a Canadian online university. It discusses the university's distance education model and enrollment statistics. The document then reviews different generations of learning pedagogies from instructivist to connectivist approaches. It presents a case study of Athabasca University's Elgg social networking installation called "Athabasca Landing" which was created to support both formal and informal online learning communities. The objectives of the project were to investigate individual and group learning in online environments, allow interaction and collaboration across the distributed university community, and explore next generation learning support systems beyond traditional learning management systems.
