At my university, most of the upper-level classes had some kind of group programming project component. We were required to use SVN, although no formal instruction in its use was given. You were expected to figure it out on your own or communicate with other students who knew how to use it already. (This was an ongoing theme in the curriculum.)

The approach worked very well. From an instructor's point of view, you can see who is (and who is not) contributing to a project if you have access to the repositories.

Personally I don't care for Subversion, but it might be easier to grasp for a first-timer.
