STEM education continues to suffer, especially among minority students attending urban schools. It’s becoming clear that to address these challenges we need to break away from traditional paradigms of instruction that stifle student interest and success. This project presents one possible solution: MathMaker: a curriculum where students learn math concepts and procedures by designing and programming their own digital games. Developed through the mapping and integration of mathematics Common Core State Standards to a range of game design and development processes, the MathMaker curriculum comprises a series of activities that guide a student to a deeper conceptual and practical understanding of mathematical principles. MathMaker has successfully improved the math scores of predominantly low income and minority students in Los Angeles, and the continued funding from Verizon will see new modules and extended reach into new schools.
