This article contains guidelines for selection and design of audiovisual materials pertinent to the teaching of infection control. Clarity, rate of presentation, and color are emphasized because they may correlate directly with effective presentation and learner comprehension. The use of audiovisual programs may cut presentation time in half, thereby achieving long-term cost-effectiveness. Slides project well if appropriate color combination is used, and if copy is limited to six double-spaced, very short lines. Specifications for effective use of color are summarized in the text.
