"Information Systems" sounds like the type of tedious college course students might feel OK about occasionally skipping. But the students at Boston College's Carroll School of Management make it to that class early and stay late.

The reason? Professor John Gallaugher, whose lectures on the technologies that drive and change the business world are really more of a master class in entrepreneurship. With an open-source textbook that he updates yearly, the course is as current as possible, touching on how social media drives consumers, what small businesses need to know about "the cloud" and other topical subjects.
