Investigates a museum exhibition design assumption that visitors develop conceptual understanding of a science topic after utilizing a cluster of conceptually related exhibits which lack explicit concept labeling.

Explores to what extent and for which visitors do free-choice learning settings accomplish their educational mission. Uses data collected at the National Aquarium in Baltimore to determine whether grouping makes it possible to discern the nature of changes in aquarium visitors' conservation knowledge and attitudes.

Validity of using time and behavior as predictors of learning was tested by collecting detailed visitor behavior and time expenditure while interacting with a participatory museum exhibit. Data from 12- and 13-year-olds (N=63: 32 males, 31 females) support the feasibility of using these predictors. Learning was measured using a 14-item test.…

Discusses the learning potentials of science museums. Examines studies that relate to visitor use and learning. Contrasts learning in museums with most school-based learning, particularly with regard to the museum's emphasis on the use of objects as the focus on learning. (TW)
