This article summarizes methodology and key findings from research to determine the effectiveness of several aspects of the Old Woman Creek National Estuarine Research Reserve on Lake Erie visitor center for providing public information about the value of estuaries. Researchers investigated how knowledge and attitudes of adults change with each visit, the factors that contribute to differing visitor experiences, how types of exhibits, readability, and placement relate to knowledge changes, and if a computer can serve as a testing device in a visitor center.
