When they like something, they learn it. Just like we do. What we need to do is put the student back at the center of the universe. Only then can we encourage some movement. Expecting them to be motivated by our perspectives is a little like encouraging your horse to take you to town by telling him about the beer you'll have when you get there.
Beer has no value to a horse, no meaning, no relevance.
And once you see the value in something, you are intrinsically motivated. But if you don't get there, the trip was a failure. You have learned nothing other than your own inferiority. But even the humble lecture can have a lasting impact if it begins with the student. Third, we should actually deal with our own inferiorities.
