I think there's a 4th type of value that students derive, implicitly, from courses that involve physical participation, especially: personal connections. Often these last well beyond the class, and many prominent businesses have been built by people who met in college.

Instructor aspects that would predict a student body likely to be a good pool of connections include assigning group tasks, encouraging peer-to-peer communication (e.g. debates, playing devil's advocate), organizing field trips, and borrowing from the corporate world: team-building exercises and outings in general.
