The document provides a brief history and overview of Massive Open Online Courses (MOOCs). It defines MOOCs as massive, open, online courses and notes that while early MOOCs focused on connecting networks of learners, more recent MOOCs emphasize curriculum and assessment like a traditional textbook. As an example, it discusses the University of Edinburgh offering six MOOCs on the Coursera platform that have attracted over 300,000 students since 2012. It also notes a tension between individual learner-centered and curated/distributed network models of MOOCs.
