Khan Academy - Use of MAP Accelerator Associated with Better-Than-Projected Gains in MAP Growth Scores

Grantee: Khan Academy

Study Type: Correlational Study

Principal Investigator: Khan Academy

Project Description: This is a correlational study that examines the relation between math achievement and student engagement with the MAP Accelerator, an intervention developed by Khan Academy and NWEA to support students’ personalized learning in math based on the prior math achievement. The study sample was comprised of data from 180,307 students and 5,818 teachers from 99 school districts across the U.S. The study took place during the 2020-21 school year.

Key Findings: Results indicate that students using MAP Accelerator for 30 or more minutes a week throughout the school year showed greater-than-expected growth, on average, from fall 2020 to spring 2021 on their MAP Growth tests compared to normative growth based on pre-pandemic trends. On average, students in classrooms that engaged with MAP Accelerator at the recommended dosage of 30 minutes per week exceeded growth projections by nine percent to 43 percent, depending on grade. These trends were consistent across grades and student demographic subgroups, such as race/ethnicity, gender, and the proportion of students in a school eligible for free/reduced-price lunch.

Summaries of Research Grants

As a leading education funder, we are dedicated to advancing the belief that “evidence matters” through novel, methodologically sound, and actionable research that uncovers programs and models with the potential to positively improve outcomes for all children. We believe research is a key way to increase awareness of what’s effective and to impact evidence-based decision making and practice across our main grantmaking areas: early childhood, informal STEM education, and K-9 programs that include supporting educators and student-centered learning environments.

Aligned with our core value of “learn better, together,” Overdeck Family Foundation is committed to promoting transparent research practices by lifting up timely findings of the research we fund. We update this page as research is concluded and published, ensuring transparency for the field and our grantees.
