Diana Laurillard explains why a model based on unsupervised learning is not the answer.
"Free online courses that require no prior qualifications or fee are a wonderful idea but are not viable. … Moocs are depicted as a disruptive technology because they involve no ongoing teaching expenses and cost the same to run no matter how many students enrol. But the idea that “content is free” in education is one of several myths that have helped to inflate the bubble of hype. … Another myth is that students can support each other. … Nor will Moocs solve the problem of expensive undergraduate education or educational scarcity in emerging economies. This is just a cruel myth. … [Finally], education is not a mass customer industry: it is a personal client industry."
