What We Believe |
Our Mission

The mission of the Delaware Mathematics Coalition is to identify, endorse, and design high quality synergistic professional learning opportunities and experiences that support the actualization of research-based norms for teaching and learning mathematics. As an organization, the Coalition advocates and supports at the state and district levels for the implementation of these practices in every classroom so that all students gain the mathematics proficiency necessary to graduate having successfully completed a rigorous, meaningful twenty-first century education that prepares them for careers, college, and citizenship.

About Us.

The Delaware Mathematics Coalition (DMC) is a strong alliance of public and charter school mathematics supervisors, higher educators, Department of Education leaders, and representatives from the business community. Monthly meetings of the DMC provide opportunities for the stakeholders to engage in meaningful conversations related to their role as instructional leaders, their mutual efforts to share best practices and problem solve challenges, and their interest in becoming more influential and persuasive leaders.

As a mathematics leadership organization, DMC members envision classrooms in which confident and competent problem solvers flourish; all students are productively engaged in challenging mathematics instruction, and all teachers are supported in their efforts to become more knowledgeable and reflective practitioners. DMC members recognize the tremendous value of professional learning and professional development in leveraging school change and communicate their commitment to their vision and mission through their ongoing support and high engagement in DMC-sponsored programs.

The nucleus of the organization is the district and charter schools in the state with governance of the DMC is supported by the Board of Directors and the DMC Executive Board (EB). The EB consists of district partners from each county in the state, a Charter School member, Department of Education Math Education Associates, a Delaware higher educator of mathematics, the Executive Director of the DMC, and a business leader represented by the Executive Director of the Delaware Foundation for Science and Mathematics Education. The team works collaboratively to support the development and evolving progress of the organization’s equity-focused strategic plan, coordinates details regarding monthly meetings, and provide ongoing guidance regarding the coalition’s mission and vision. The Executive Director also serves as the coordinator for the DMC’s statewide and site-based professional learning  and coaching efforts and oversees the work of the DMC Professional Teaching & Learning Team.

The Critical Role of Thought Partners & Advisors

Higher education, Department of Education, and business leaders, while not voting members of the DMC, serve as critical advisors to the organization. During the past five years, the Delaware Foundation for Science and Mathematics Education (DFSME), a non-profit organization with a history of supporting STEM in the state has served the fiscal manager for the DMC. The work has included managing the funding for the DMC’s TRU-Math (MSP) and Leadership Coaching Lab (funded in part by the Longwood Foundation) projects. DFSME is an advocate for Delaware Math Coalition’s statewide reform efforts and engages partners from the business community (e.g., Ashland, DuPont, Labware, Verizon, etc.) in the ongoing work of the organization.

Delaware Department of Education (DDOE) mathematics leaders work in collaboration with DMC leaders to ensure that policies and practices of the mutual organizations work synergistically to enhance Delaware districts’ mathematics programs. Through the Math Science Partnership and other state administered grants, over the years, the Department of Education has been instrumental in providing access to much needed funding to support the DMC’s statewide and school-based professional learning efforts. DOE Education Associates for Mathematics are integral members of the DMC Executive Board, participate in short and long-term planning, and play an integral role in developing the organization’s equity-focused strategic initiatives.

Meet Our Professional Teaching & Learning Team

The Delaware Mathematics Coalition professional teaching and learning team is comprised of highly-respected professional learning experts, thought partners, and coaches with a history of success as mathematics leaders in the state. The team includes the project director, Dr. Jamila Riser, and eleven professional development facilitators, coaches, and connectors. The role of connectors is to initiate school-based outreach with the goal of reinforcing school-based continuation of the work connected to our statewide workshops by providing follow-up coaching cycles and building school-based leadership capacity. Our advisory group consists of University of Delaware professors Dr. James Hiebert, Dr. Mandy Jansen, and Dr. Erica Litke.

Delaware Mathematics Coalition

The Delaware Mathematics Coalition is committed to building local and state level mathematics leadership capacity. Teacher leaders, coaches, and math supervisors from local district and charter schools have been integral to the success of our professional learning programs (Leadership Coaching Lab, New Normal PBL Academy (Math Camp), Desmos Champions, etc.). In our efforts to cultivate the skills, knowledge, and growth of our community of math leaders, we involve these and other educators in our statewide professional learning projects.
