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.
In this paper, Minda Borun of the Franklin Institute discusses the publics' naive notions of science and how museums provide the opportune place to study the pre-existing misconceptions of visitors of all ages. Borun reveals findings from the Franklin Institute's 18-month study to discover visitors' naive notions about gravity and air pressure and to develop exhibits which help restructure these concepts. The project is intended to establish a new model for the design of effective science museum exhibits.
