Online learning involves courses offered by primary institutions that are 100% virtual, excluding massively open online courses (MOOCs). Online learning, or virtual classes offered over the internet, is contrasted with traditional courses taken in a brick-and-mortar school building. It is the newest development in distance education that began in the mid-1990s with the spread of the internet and the World Wide Web. Learner experience is typically asynchronous, but may also incorporate synchronous elements. The vast majority of institutions utilize a Learning Management System for the administration of online courses. As theories of distance education evolve, digital technologies to support learning and pedagogy continue to transform as well.
