The hypothesis underlying this evaluation effort is that a systems-based evaluation design attentive to a distributional theory of culture will help policymakers and evaluators better understand the role that structural, cultural, and individual level factors play in influencing a reform effort. The study describes a specific activity of the SCALE MSP-professional development workshops for STEM faculty, and then argues that these efforts can not be adequately understood without analyses of cultural models, which I provide. The claims in this research address institutional change and sustainability, which are key features of the MSP program and of widespread concern to the broader STEM education community.
