Peter Struck teaches Greek and Roman mythology at the University of Pennsylvania, but his lectures can also be viewed over a platform called Coursera. Over 5 million people around the globe have joined the platform and become 'Courserians'. Free online lectures are known as 'massive open online courses', or 'MOOCs' for short. In Germany, this form of digital dissemination of knowledge is still in its infancy. However, the Berlin-based learning platform Iversity now offers online courses in everything from medicine to creative writing -- in German and English.
