“…While many researchers have documented the positive impacts of non‐formal museum‐/zoo‐/aquarium‐type learning experiencing on enhancing visitors' environmental knowledge, awareness, attitudes and pro‐environmental intentions (Ardoin, Wheaton, Bowers, Hunt, & Durham, 2015), relatively few studies have evaluated whether there is any lasting effect on behaviour or pro‐environmental intentions (Ballantyne, Packer, & Falk, 2011). There are additional minimal empirical follow‐up studies to monitor whether short‐term non‐formal learning experiences are being translated into longer‐term actions (Ballantyne, Hughes, Lee, Packer, & Sneddon, 2018). The intent of this study has been to examine the impact of visitors' experience with a large museum and aquarium in Taiwan, namely, the National Museum of Marine Biology and Aquarium (NMMBA), with a particular focus on the engagement effects of interpretative interactions, a key function of maritime museums in conveying conservation messages.…”
