This paper discusses how museums can encourage chaperones to facilitate deeper experiences for students during field trips. The authors describe how the California Science Center's ThinkSCIENCE! Pathways field trip program addresses this issue. Pathways asks chaperones to become facilitators by using "chaperone sheets," sets of materials containing gallery-specific questions, activities, and points of interest to help chaperones engage students in discussion. This article cites findings from a rigorous formative evaluation of these chaperone sheets and the program in general.
