Are Missourians any different from people elsewhere in wanting to be shown? I don't think so—they are just a little more frank about demanding visual proof. It is difficult enough to describe many common, everyday objects; If a group is unfamiliar with an object or its use, the difficulty Is compounded. But a picture, a drawing, or the actual object demonstrated readily communicates the thought to an audience. And it is easier to describe familiar things than bacteria, which the audience cannot see, or a concept such as “cleanliness is a way of life.” Visual aids can assist in meeting these communication challenges. Because the effective use of visual aids is such a large subject, I will limit my discussion to the correlation of visual aids to training methods appropriate in training food-service managers.

Author's Note: When I was asked to present this session at the 55th Annual Meeting of IAMFES, I asked why the planning committee wanted a session on Visual Aids. The answer: “Because the meeting was to be held in Missouri, the show-me state, and visual aids are the best way to communicate with folks in that area.”
