The teams of faculty "change agents" involved in the SAGE 2YC project implemented high-impact, evidence-based instructional and co-curricular practices at their own institutions to stimulate improved STEM learning, broadened participation, and a more robust STEM workforce. They worked with administrators to institutionalize these changes, and also propagated these practices to colleagues at 2YCs and four-year colleges and universities (4YCUs) in their region via an local professional development events. Cohort 1 of teams began their work in the 2015-16 academic year, and Cohort began in 2017.
