Most important, psychologically, it makes the media an integral part of the instructional environment, like the chalkboard. Technology is not just an afterthought. A centrally-schedule, college classroom is a room of a dozen users in several disciplines with multiple teaching styles. Designs should be inclusive, offering many options while excluding very few options. Expensive, long-term items should be generic.
Inexpensive items can be more specific.
The design should focus on a user-friendly approach with a great deal of attention devoted to simple, operational signage and controls. Faculty should be able to operate equipment at eye-level without undignified crawling around on the floor or fumbling with poorly labeled controls in the dark. In addition, dual window coverings, multiple screens and functional light switching give faculty control over the classroom environment. The presentation space in the front of the room is precious. It should be covered with blackboards and multiple screens so you can use the board and project images at the same time.
