At many colleges and universities there is considerable interest in offering courses online. Yet some faculty members express skepticism that online courses are not as rigorous as their classroom counterparts. This paper explores what happens when the exact same service learning computer science course was offered in a classroom and online environment to similar students at one university. The author found that there were no significant differences in learning outcomes. There were, however, differences in the types of students who tended to enroll in the online course.
