An informal study found that zoo visitors want to know not just the name, weight, and age of animals in a collection, but also about diet, reproduction, life span, and behavioral characteristics. What kinds of learning opportunities, beyond enhanced signage, can be offered to the sophisticated new breed of visitors in zoos, aquariums, and nature parks? This digest focuses on how learners process information and how professional staff and visitors can promote learning at the zoo. Discussion includes: informal learning environments, learning styles, implications for informal learning environments, and reflection as a retrieval strategy. (Contains 13 references.) (MKR)
