Educating the public about wildlife and conservation has long been a core component of many zoos' mission statements (Patrick, Matthews, Ayers, & Tunnicliffe, 2007). However, research has demonstrated that most patrons visit zoos to be entertained and to socialize rather than to be educated. Thus, greater emphasis is now placed on encouraging learning through zoo exhibits that are designed to educate while still remaining fun (Packer & Ballantyne, 2004). This study examined the effects of two augmented-reality iPad apps [1) an inquiry based app and 2) an information based app] on adult patron learning about the Komodo dragon and the Hippopotamus at a moderately sized zoo in South Texas. Significant differences were found in the learning of adult patrons. Although ratings were high, no significant differences were found between the conditions on satisfaction.
