Massive Open Online Course (MOOC) was entered at Wikipedia as:
"A massive open online course (MOOC) is an online course aimed at large-scale interactive participation and open access via the web. In addition to traditional course materials such as videos, readings, and problem sets, MOOCs provide interactive user forums that help build a community for the students, professors, and teaching assistants (TAs). MOOCs are a recent development in distance education.
Features associated with early MOOCs, such as open licensing of content, open structure and learning goals, and connectivism may not be present in all MOOC projects, in particular with the 'openness' of many MOOCs being called into question."
As of this blogging, there is still no self-paced on-demand MOOC course that generate free certificate.
