The most popular online training courses in 2014 were Coursera's "Introduction to Databases" and Instreamia's "University Spanish Level 1," according to Dhawal Shah on edSurge. The top courses were rated based on data from Class Central.
Massive open online courses, known as MOOCs, were introduced in 2011, and initially the content of the coursework often focused on computer science or engineering, says Shah. In 2014, however, the largest category of course offerings center on the humanities. The fastest-growing sector of online courses is geared towards education and teaching. The most popular provider of online training courses is Coursera, which is partnered with top universities and organizations to offer free courses, according to Coursera's mission statement.
