This book is the product of over twenty years of research examining the impact interpretation has on its audiences. The results of over thirty research studies are examined to help practitioners, managers, and students successfully convey interpretative messages. The findings, offered through vignettes and case studies, are the product of long-term assessments that range from three months to three years following an interpretive experience. Interpretive theory, techniques, strategies and experiences are discussed in relation to a variety of settings including traditional programs, school field trips, visitor center and campfire programs. Hence, this is the first and only book on interpretation based on interpretation research.
