Scaling up educational interventions in the STEM (Science, Technology, Engineering, and Mathematics) field is critical but under-researched. We review and draw implications from a series of studies investigating the long-range impact of an implementation of an early mathematics scale-up model based on learning trajectories. Lasting effectiveness…

Early fine motor ability is significantly associated with later achievement, even after controlling for typical child-level predictors of school outcomes. Previous longitudinal studies have confirmed this but typically have not included low-income, at-risk populations. Research has distinguished two different aspects of fine motor skills: those…

This report examines the population of Alaska Native students who are classified as English learner (EL) students and how EL policies function for these students, focusing on EL identification, classification, service provision, and reclassification as fluent English proficient. Alaska is one of several states where Indigenous students make up a…

Although some research-based educational practices have shown promise, many fail to be implemented at a scale that affects more than a small proportion of children. Further, research on interventions for young children includes mixed results, with most documenting "fadeout" of effects after several years, but some showing lasting…

We analyzed two nationally representative, longitudinal data sets of U.S. children to identify risk factors for persistent mathematics difficulties (PMD). Results indicated that children from low socioeconomic households are at elevated risk of PMD at 48 and 60 months of age, as are children with cognitive delays, identified developmental delays…
