Your advice on that has helped, thank you. I have also chosen to "pretend" not to know certain moves so they might prove their knowledge of what they have learned.
Easy: I give them D's and threaten to fail them if they do not write their own papers. Their previous teacher apparently let them slide on this front from time to time.
I also assign students who choose to 'take notes' with their phones (i.e. play candy crush or clash of clans) the pleasure of watching the entire Roots series within a week and write a paper on it. All should be taking notes with paper and pen, so you know.
