Several instruments have been developed to assess student images of scientists, but most require children to respond in writing. Since not all children can respond appropriately to written instruments. Chambers (1983) developed the Draw-A-Scientist Test (DAST) in which children's drawings are rated according to particular characteristics present or absent in the drawings, allowing researchers to determine the images of scientists children hold. In order to improve the objectivity and interrater reliability of this means of assessment, the authors built upon Chambers' study to develop a

In this case study, Carey Tisdal, internal evaluator at the St. Louis Science Center (SLSC), discusses the use of teacher response groups in the development of the school visit program at SLSC. This paper uses a case method to describe: (1) the context of policy and program issues from which the study arose, (2) the reasons this specific method was selected, (3) the development of a data base, (4) how the method was implemented to recruit and interview teachers, and (5) an analysis of the limitations and benefits of the methods.
In this paper, researchers at Monterey Bay Aquarium share findings from a study of self-guided school groups. This report focuses the meaning of "running amok" as it applies to these self-guided school groups and questions general assumptions about self-guided school groups.
In this paper, researchers from Science Learning, Inc. discuss findings from an evaluation study that used interpretive carts to analyze visitor conversations. Researchers collected data using the "Rock Talk" cart to inform the redesign of the Geology, Gems & Minerals Hall at the Smithsonian's National Museum of Natural History.
