Description: Advocating for equitable mathematics instruction that advances learning opportunities for all students is essential, but where to start? In this workshop, we share the Proactive Coaching Framework (PCF)—a tool that guides mathematics coaches’ and leaders’ goal setting in ways that advocate for research-informed practices and facilitate critical conversations about initiating, assessing, and sustaining change within schools. Participants will engage in multiple peer rehearsals (similar to role plays) based on realistic classroom vignettes centered on fraction concepts. This workshop supports the facilitation of teachers’ development of productive beliefs and establishment of new norms of instructional practice.
