I’m really impressed with Coursera, which offers free online classes through some of the world’s best universities. Each course is structured differently, but most are five to eight weeks long and consist of weekly video lectures, written assignments, quizzes, and forums for engaging with your professor and classmates. Coursera has a preponderance of technology and computer science offerings, but there are dozens of art, philosophy, finance, and nutrition classes as well. So, are massive open online courses (MOOCs) the future of education? That remains to be seen, but they provide an exciting service for people who are eager for information and instruction without a hefty tuition payment.
