Pedagogy: story lines for introducing GR?
Edit- I also introduce GR by analogy to the surface of the Earth- moving North-South vs. East-West introduces the notion of a 'fictitious force', combined with the paradox that force-free mechanics (motion in straight lines) appears violated for free body motion, because we can cancel gravity with a fictitious force. Thus gravity and curvature are interchangeable.
I don't know how much sticks, but I enjoy telling the story... :)

I cite this as a way that you might attract liberal arts majors who might be more interested in the historical side of GR. :)
After all, we cannot simple come from a simple Piagetian based teaching style but must include social communication, scaffolding and interaction (Vygotisky) while appealing to twenty first century learning need to address different intellengences (music, art, kinestetic, etc.)
