Examining the Role of Unpacking 3-Dimensional Teaching and Learning in Museum-Based Professional Development

The purpose of this study is to examine changes in teachers’ attitudes and behaviors towards three-dimensional instruction after participation in a Museum-based professional development program. The study design includes a preand post-survey measuring attitudes towards three-dimensional instruction along with observation rubrics and facilitators’ field notes. A preliminary analysis of early data is used to describe implications of applying the “backwards design” model in professional development.
