Final conclusions of a nationwide study of the use of the phonoviewer in the Expanded Foods and Nutrition Education Program (EFNEP) are given to supplement data and specific conclusions in two earlier reports. Based on mailed questionnaires returned from EFNEP coordinators, nutrition specialists, and a sample of county home economists augmented by a study of use by EFNEP aides and reaction of youth and adult programs participants, it is held that the phonoviewer has justified the investment in purchase of instruments and shows and the development of shows. Specific findings about the use of instruments and shows, along with user reaction, are given. Seventeen conclusions summarized the directors' recommendations for further implementation of the program. (SK)
