Certain areas in the social studies can be effectively taught in a non-classroom setting. This experiment determined if, in a supermarket situation, consumer preferences (as measured in sales figures and augmented by questionnaire data) could be altered by the addition of nutritional information to the labels of sixteen items which had moderate sales in a sample of two matched supermarkets. Two labeling methods were compared--that of the FDA (Food and Drug Administration), listing percentages of specific nutrients contained in one portion of a labeled item, with the FE (Food Equivalent), consisting of a diagrammatic comparison between nutrients in one portion of a well-known reference food. Analysis showed that the FE label was significantly more effective in promoting the sale of the more nutritious item, and that the addition of labels effected a change in consumer preference. Further, it seems safe to generalize that customers are open to some sort of educational process at the point of contact, if that contact is made in a certain manner, illustrating the need for planning in a methodological approach. The problems of adapting content and identifying certain steps can be dealt with and, moreover, an instructional model can be designed for use in such non-classroom instruction. (Author/SJM)
