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.
Research Questions
- What is the relationship between time spent on MAP Accelerator and observed growth in math achievement?
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.
