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.
