How do you teach people who don’t want to learn?

I’m at a loss.  I lecture, I make them do in-class work to reinforce the lecture and still they just won’t learn.  And I don’t think it’s that they can’t – they don’t want to learn.

Few things are more frustrating than asking, “what don’t you understand?” and getting “everything” as the answer.   How do I fix that?  I can’t reteach the entire course.

So much for a good semester.  😦
