Evaluating DMI Study Overview
Evaluating DMI is a study of the Developing Mathematical Ideas (DMI) elementary math professional development program using scientifically rigorous experimental methods. Evaluating DMI builds on prior work showing the impact of DMI on teachers' mathematical and pedagogical knowledge. Our study looks at how taking part in DMI affects elementary teachers' knowledge and teaching practices, and how it affects what their students learn about number and operations.
Evaluating DMI works with Grades 1-5 teachers and students in urban and suburban Massachusetts school districts who are using the Investigations in Number, Data, and Space curriculum. Our study gathers evidence of the impact of implementing DMI at scale. It also builds and tests new measures of teacher content knowledge and teaching practice.
