Predicting Persistence and Fadeout Across Multi-Site RCTs of an Early Childhood Mathematics Curriculum Intervention
This study examined predictors of persistence and fadeout across multiple cluster RCTs that evaluated a preschool mathematics curriculum. We used meta-analytic methods to explore how impacts on student mathematics achievement faded between post-test (i.e., endline) and one-year follow-up. We… more →

Questions about the stability of psychological constructs, skill generalization, and transfer have long motivated psychological research.

How General is Educational Intervention Fadeout? A Meta-Analysis of Educational RCTs with Follow-Up
Researchers and policymakers pursue educational interventions with the goal of altering children’s long-term trajectories. However, many effects fade quickly after interventions end. Researchers have sought to address the fadeout problem by identifying characteristics of interventions that lead… more →

High-quality preschool programs are heralded as an effective policy tool to promote the development and life-long wellbeing of children from low-income families. Yet evaluations of recent preschool programs produce puzzling findings, including negative impacts, and divergent, weaker results than… more →
