Delaware Mathematics Coalition Building Local & State Level Math Leadership Capacity 

“I have found a community that truly connects critical mathematics education research to concrete practice. We reflect on content in a way that deepens my own understanding and connections of important mathematical ideas, discuss pedagogical moves that we can use to encourage student thinking and agency within our classrooms, and focus on how we can become better teacher leaders in our building.”  (TRU-Math Participant: RBS, 2017) As a community, the Delaware Mathematics Coalition (DMC) is committed to creating more powerful and robust mathematics teaching and learning environments in Delaware classrooms. As an alliance of partners, DMC members continually plan for ways to share resources, provide sustained learning opportunities for their teachers, coaches and administrators, and collectively build local and state mathematics leadership capacity. Across the years, the DMC has developed a successful model of professional learning and extended support grounded in research and focused on increasing participants’ content and pedagogical knowledge and skills (Horizon, RBS). Our investment in building mathematics leadership capacity spans a decade of in-depth study that has culminated in a proven cycle of inquiry and reflection involving content-focused coaching. The use of protocols developed in collaboration with our higher education and evaluation partners further enhances and sharpens our efforts to promote more conceptually-grounded teaching, mathematical sense making, representations-based argumentation, and student agency in Delaware classrooms. The DMC professional development team is comprised of a strong cadre of highly respect professional development experts, thought partners, and coaches with a history of success as mathematics leaders in the state. They have invested years building relationships with district partners and served as mathematics supervisors, coaches, assessment writers, district specialists, project leads, and recognized teacher leaders.
