MOOCs are massive open online courses that are open to unlimited participants, have no fees, and provide limited interaction with instructors. They aim to provide educational opportunities to as many people as possible. MOOCs can be used to explore new pedagogical approaches and share course content between universities. While they do not provide credit, some do offer assessments. There are two main types - cMOOCs that emphasize connective knowledge and xMOOCs that use an instructional approach. MOOCs allow for automated assessment and can benefit learners through open access to education.
