Although the material in this booklet is specifically designed for National Park Service employees, the subjects covered apply to all oral interpretive programs. The first chapter considers researching and writing the script and music and dance in the script; chapter 2 discusses settings, including speaking positions, decor, and properties; equipment, and sound are the focus of chaper 3. The intent of the speech and the response of the audience are considered in the fourth chapter; and the fifth chapter concentrates on presentation, including appearance and action. The four appendixes are devoted to discussions of ways to add dramatic values to an existing interpretetive program, a new interpretive project, voice study material, and selection of personnel. (LL)
