Credentials: Many MOOCs offer college credit or certificates of completion, which help to legitimize and formalize the learning. At leading MOOC provider Coursera, 14 percent of courses offer verified certificates, for which registration costs between $30 and $100 depending on the course’s length and content. Seventy-five different Coursera courses offer verified certificates, through what the company calls its ‘Signature Track,’ and five of those offer college credit eligibility – they include Pre-Calculus and Algebra from UC Irvine, Calculus from UPenn, and from Duke one class on genetics and evolution and another on bioelectricity.In the workplace, certificates function as an incentive for employees to complete optional training or skill development courses, because they’ll have something to show for all their work.
