Prezi presentations are beautiful, modern, and a fantastic replacement for or addition to Powerpoints and other more standard presentation material in the classroom. The fluidity or "zooming" nature of these presentations appeal to students' sense of novelty, and keeps them engaged even when the topic might seem dull.
This is a short, fun lesson on the nature of historical bias and how to recognize it. I used it for a discussion based class and it was a great success. There are youtube videos embedded with trailers from popular movies. Each trailer is edited differently to make you think you're watching a different kind of movie. Great discussion starter!
