“the engagement of learners who self-organize their participation according to learning goals, prior knowledge and skills, and common interests”
(McAuley, Stewart, Siemens, & Cormier, 2010)
Intentions of distributed MOOCs (aka cMOOCs)

Learners to “acquire learning for themselves, rather than have learning served to them by some provider or institute”
(Hollands, 2014)
