A MOOC (Massive Open Online Course) integrates social networking, an expert facilitator, and freely accessible online resources to build active engagement among hundreds to thousands of self-organizing students. While MOOCs may have predefined timelines and topics like traditional courses, they generally have no fees, prerequisites, participation expectations, or formal accreditation. Word of a MOOC spreads through social networks, and students engage and share ideas using digital tools rather than completing formal assignments. MOOCs aim to provide free university-level education to many, lower education costs, and encourage open online learning.
