If you are like the majority of teachers, you will have only one computer in your room, or at most just a few, and their placement may be pre-determined by location of power and cable outlets. If so, you need to think about computer placement early in the process of setting up a room. Once the location of computers is set, locations for desks, high-usage shelves, and other moveable items can be chosen more sensibly—in general so as to minimize distractions to students and to avoid unnecessary traffic congestion.
