With support from the Bill and Melinda Gates Foundation, researchers and experts in mathematics education developed the Mathematics Design Collaborative (MDC) as a strategy to support the transition to Common Core State Standards in math. MDC provides short formative assessment lessons known as Classroom Challenges for use in middle and high school math classrooms. UCLA CRESST’s study of ninth-grade Algebra 1 classrooms in Kentucky implementing MDC showed strong support from teachers for the intervention and a statistically significant positive impact on student scores on the PLAN Algebra assessment, as compared to similar students statewide in Kentucky. The following are appended: (1) MDC Instruments and Rubrics, (2) MDC Teacher Log Descriptives; (3) MDC Teacher Survey Descriptives; (4) Analysis of MDC Student Work Artifacts; and (5) Quasi-Experimental Analysis of MDC Effects.
