This is my teaching nightmare

Professor Christensen did something “truly disruptive” in 2011, when he found himself in a room with a panoramic view of Boston Harbor. About to begin his lecture, he noticed something about the students before him. They were beautiful, he later recalled. Really beautiful.

“Oh, we’re not students,” one of them explained. “We’re models.”

They were there to look as if they were learning: to appear slightly puzzled when Professor Christensen introduced a complex concept, to nod when he clarified it, or to look fascinated if he grew a tad boring. The cameras in the classroom — actually, a rented space downtown — would capture it all for the real audience: roughly 130,000 business students at the University of Phoenix, which hired Professor Christensen to deliver lectures online.
