This research provided empirical benchmarks for the amount of attrition that can arise from natural rates of student mobility. Student-level, school-based longitudinal evaluations of education practices and interventions often encounter participant attrition when students move away from, or drop out of, study schools. In some cases, this mobility-induced attrition simply decreases sample size, weakening the study's power to detect a treatment effect. Attrition can also introduce bias into an...

The purpose of the project is to provide applied researchers with clear, research-based strategies that build on recent methodological advances to improve the use of propensity score matching in education research. Propensity score matching has become a common tool for estimating causal effects in education research over the past 15 years. However, most of the methodological research and guidance regarding the use of propensity scores—and matching more generally—overlooks important compl...

The purpose of this project is to adapt, evaluate, and prepare to scale CFI+PALS, a product for fifth grade students that combines Classwide Fraction Intervention (CFI) with Math Peer-Assisted Learning Strategies (PALS). COVID-19 learning loss has impacted students in high-poverty elementary schools, particularly in math. To accelerate math learning, teachers in these schools need innovative, evidence-based methods that incorporate a dual focus on grade-level content and content from earlier...

In this project, researchers will investigate how online credit recovery affects student content knowledge, credit accumulation, and graduation, relative to retaking failed courses in a standard face-to-face format. They will also describe the ways in which online credit recovery provides students with different instructional experiences compared to repeating the standard face-to-face (f2f) course. School districts across the country are increasingly using online courses to expand credit rec...

The University of California, Los Angeles departments of education and psychology established an interdisciplinary predoctoral training program focused on (a) advanced quantitative methodology for improving education practice and (b) mathematics teaching, learning, and assessment.
