While the opportunity to engage in scientific reasoning has been identified as an important aspect of informal science learning (National Research Council, 2009), most studies have examined this strand of science learning within the context of physics‒based science exhibits. Few have examined the presence of such activity in conjunction with live animal exhibits at zoos and aquariums. A video study of 41 families at four touch‒tank exhibits, where visitors can observe and interact with live marine species, revealed that families engaged in making claims, challenging claims, and confirming claims as well as other actions associated with scientific reasoning such as applying prior knowledge, making and testing predictions and hypotheses, and constructing arguments. We provide examples of scientific reasoning and examine the role of claims in promoting scientific reasoning. Implications for rethinking learning opportunities and interpretational approaches at touch tanks, as well as examination of the unique characteristics of these and similar exhibits, are discussed. © 2012 Wiley Periodicals, Inc.

Research has demonstrated that conversations among museum, aquarium, and zoo visitors can be a clear indication of active learning, engagement, and participation in scientific reasoning. This descriptive study sought to determine the extent of talk about ecology-related topics exhibited by family groups visiting marine touch tanks at four Pacific coast aquariums. In particular, conversations were examined to determine the kinds of ecology topics discussed and the influence of exhibit features such as tank format and interpretive staff interactions on the extent of talk about ecological topics. Findings suggest limited talk about ecology by families during their visit to the exhibit -regardless of whether the tank resembled a real tidepool habitat or not. However, data revealed that talk about ecology between guests and staff was significantly longer than was ecology-talk among guests only, suggesting that supplemental interpretation by staff members or volunteers may be necessary to explicitly encourage such discourse at touch tanks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
