Who needs college credit when one can have a makeshift diploma from a superstar professor? One such example is David Wiley who taught an online course at Utah State University recently and let anyone fully participate, even if they were not enrolled. The unofficial students paid no tuition and got no formal credit, but they did end up with something tangible: a homemade certificate signed by Mr. Wiley, who at the time directed the Center for Open and Sustainable Learning and is well-known in the area of online learning. Open Teaching is the name Mr. Wiley and others use for their experimental knowledge giveaway. It suggests how the Web could soon force colleges to re-examine their offerings in the age of digital delivery. This article describes how universities may soon follow the lead of Mr. Wiley and others who give diplomas away.
