This chapter discusses the role of zoos in education. Zoos claim to have an educational function, but most of the studies that have been conducted in zoos have examined the educational value of single exhibits and have collected data from relatively small samples of visitors. Some studies have recorded changes in the knowledge or future behaviour of visitors following a zoo visit but others have not. Zoos in general tend to overemphasise their educational value based on very little scientific evidence. Some zoos engage in educational outreach work in schools and communities, and some of this work takes place in countries other than those where the zoos are located. Zoos make an important contribution to the training of future zoo professionals and veterinary staff. New technology is increasingly being used to enhance the visitor experience.
