    Abstract:
    The purpose of this study was to design, develop, and formatively evaluate a computer-based multi-media nutrition education program for adults based on the Dick and Carey model of instructional design. The 4 phases of the study included analysis, design, development, and evaluation. Seventy-two volunteers from the US Air Force, aged 18 to 50 years, participated in focus groups, an E-mail survey, or a dietitian survey to establish the program's instructional goal of applying the principles of the Food Guide Pyramid to daily food choices. Objectives, assessment instruments, content, examples, and practice questions with feedback were written in the design phase. Four modules of instruction--Familiarization with Food Groups, Serving Sizes, Modifying a Menu, and Vitamins and Minerals--were programmed using Hyper-studio. Eighteen subjects aged 22 to 40 years, with at least a high school education and an average knowledge of nutrition volunteered to participate in 1 of 2 formative evaluation phases. All subjects completed a pretest, 2 posttests, 3 embedded tests, and an attitude questionnaire to ascertain program weaknesses. One module was deleted after phase 1 because the material lacked relevance to subjects. In phase 2, only 4 of 15 subjects could identify serving sizes in module 2 and only 6 of 15 subjects could do the same on posttest 1. Back buttons and review screens were added to modules 2 and 3 to facilitate identification of serving sizes. We conclude that dietetics professionals should use systematic models of instructional design, such as the Dick and Carey model, to design effective nutrition education programs for the public.
