This is a powerpoint slide originally written by Edward (Joe) Redish from the PER group at the University of Maryland. Often, our surroundings indicate to us how we should behave. For example, if we walk into a restaurant and we see a menu is not on the wall, we know that we will sit down, order our food from a menu in our hands, eat with a knife and fork, and finally, pay. (c.f. the previous slide).

If we want our students to do something in class besides passively listen to lecture, then we need to signal to them that the frame has been changed. I try to find a plausible reason to stand on top of a table within the first few days of the Paradgims. I also talk to the students, explicitly and often, about what it is that we are doing differently, and why.
