“…Major criticisms of conservation education evaluations that examine changes in knowledge, attitudes, and behavioural intentions warn that: knowledge is a minor factor in predicting whether visitors undertake conservation actions ; changes in intentions do not always translate into actual conservation actions (Ballantyne & Packer, 2005;Smith, Broad, & Weiler, 2008); and that measures of changes in conservation actions are seldom informative about the benefits to wild species or habitats, which are the truer measures of conservation success (Ferraro & Pattanayak, 2006;Hughes, 2013;Smith et al, 2010). While research does repeatedly detect small positive changes in visitor knowledge and attitudes (Khalil & Ardoin, 2011), persistent behaviour changes due to this education, or direct benefits to conservation, are rarely evaluated or confirmed (Nygren & Ojalammi, 2017). For example, recent research has persuasively demonstrated that zoo and aquarium visitors leave with an increased understanding of biodiversity and knowledge of actions to help protect it (Moss, Jensen, & Gusset, 2015), but over a longer time frame it is difficult to attribute persistent changes to the visit (Smith et al, 2008).…”
