In this paper, Jeff Bonner of the St. Louis Science Center discusses the merits of formal versus naturalistic evaluation within the museum context. Bonner also presents the approach and findings of a two-part study designed to compare the results of these two evaluation approaches. They compared the the results of a formal analysis of the holding power, ease of use, readability of text, and overall enjoyability of nine exhibits with a naturalistic study focused on how one volunteer, two part-time employees and a staff supervisor viewed the same exhibits.
The St. Louis Science Center plans to design and develop a 2400-square-foot permanent exhibit dealing with the fields of cellular and molecular biology, including biotechnology and genetic engineering. The primary goal of the exhibit is to affect the attitudes of millions of visitors, with the secondary goal being to serve as a model for other science museums and science centers.
