One of the best is called Bad PowerPoint. It starts with stand-up comedy, and ends with students presenting truly terrible slide decks using truly terrible presentation technique, with classmates scoring them collaboratively using BINGO boards.
So often we require students to give presentations without first teaching them how to do it well. At best, we lecture them about what good presentations are, often in ways that violate those elements of good presentations!
But, as my first mentor in the teaching profession reminded me often, there is a big difference between “teaching” and “telling” students.
