This literature review by Dr Sarah Hayes (published by QAA MOOCs Network) presents a number of different perspectives from a broad range of sources relating to the nature of MOOCs and pertinent considerations of quality. The report starts with a good overview of what different MOOCS are out there: a division in 2 pedagogical styles (cMOOCs and xMOOCs) and a taxonomy with eight types (Clark (2013)) is given. Further on the report discusses quality considerations and the issues of high non-completion rates. Furthermore the author focuses on good learning and instructional design and the last part gives some ideas on opportunities and further research. An interesting read for anyone that is looking for a good overview on recent research done in the field of MOOCs.
