Stands for "Massive Open Online Course," a type of course that is completely delivered online, is open to be accessed by anyone without cost, entry qualifications or other restrictions;participant numbers are often high. These courses can have in-person components, e.g. encouraging local participant meetings, and formal assessment, but tend to use peer review, self-assessment and automated grading. There are many variations of MOOCs, focused on specific sectors, target groups (e.g. vocational focus, teachers, etc.) or teaching methods. MOOCs funded under Erasmus+ have to be open to all and both the participation and a certificate or badge of completion are free of charge for participants. The open access requirement for educational resources applies also to MOOCs and other complete courses.
