Tutoring ranks among the most versatile and potentially transformative educational tools available. Dozens of randomized experiments have evaluated preK-12 tutoring programs, varying widely in approaches, contexts, and costs. This article presents results from a systematic review and meta-analysis of tutoring field experiments. We develop a…

Reclassification is a crucial outcome for English learner (EL) students' academic progress. Though ELs spend a large portion of their academic time with general education teachers, we know little about the role general education teachers play in developing ELs' English language proficiency. Drawing from a longitudinal administrative dataset from…

Before the 2020-2021 school year, policymakers and parents confronted the uncertain trade-offs implied by the health, educational, and economic consequences of offering instruction remotely, in person, or through a hybrid of the two. Most public schools in the United States chose remote-only instruction, and enrollment fell dramatically (i.e., a…

New York City's Pre-K for All (PKA) is the nation's largest universal early childhood initiative, serving over 64,000 four-year-olds annually. Stemming from the program's choice architecture as well as the city's stark residential segregation, PKA programs are extremely segregated by child race/ethnicity. Our current study explores the complex…

This investigation studied the effects of the Multiple Literacies in Project-Based Learning science intervention on third graders' academic, social, and emotional learning. This intervention includes four science units and materials, professional learning, and post-unit assessments; features of project-based learning; three-dimensional learning…

Although writing is often used for personal reflection in teacher education, it is less commonly leveraged to imagine educational futures (Gilligan, 2020)--particularly those centered on collective liberation. Amid intersecting social crises, however, imagining futures is critically important (Ladson-Billings, 2021), and writing is a crucial step…

This study examined whether pre-K benefits persist through the end of first grade and the extent to which persistence differs based on outcome domains, subsequent classroom environments, and key subgroups of children. Data from 2,351 children living in a large and diverse county in Virginia revealed that the initial benefits of pre-K for academic…

Half of kindergarten teachers split children into higher and lower ability groups for reading or math. In national data, we predicted kindergarten ability group placement using linear and ordinal logistic regression with classroom fixed effects. In fall, test scores were the best predictors of group placement, but there was bias favoring girls,…

This study was designed to assess the effects of states' adoption of more rigorous standards as part of the current wave of standards-based reform on student achievement using comparative interrupted time series analyses based on state-level NAEP data from 1990 to 2017. Results show that the effects of adopting more rigorous standards on students'…

The public narrative surrounding efforts to improve low-performing K-12 schools in the United States has been notably gloomy. But what is known empirically about whether school improvement works, which policies are most effective, which contexts respond best to intervention, and how long it takes? We meta-analyze 141 estimates from 67 studies of…

We used multivariate generalizability theory to examine the reliability of hand-scoring and automated essay scoring (AES) and to identify how these scoring methods could be used in conjunction to optimize writing assessment. Students (n = 113) included subsamples of struggling writers and non-struggling writers in Grades 3-5 drawn from a larger…

This study examines the impacts of two AmeriCorps programs, Minnesota Reading Corps and Wisconsin Reading Corps, where AmeriCorps volunteers provide literacy tutoring to at-risk kindergarten through third-grade (K-3) students utilizing a response-to-intervention framework. This evaluation replicates a prior randomized controlled trial evaluation…

Informational text--resources whose purpose is to inform--is essential to daily life and fundamental to literacy. Unfortunately, young children typically have limited exposure to informational text. Two 9-week randomized controlled trials with 263 first-grade children from low-income communities examined whether free educational videos and digital…

This cluster randomized controlled trial investigated the impact of project-based learning with professional development supports on social studies and literacy achievement and motivation of second-grade students from low-socioeconomic status school districts. At random in within-school pairs, 48 teachers were assigned to the experimental or…

Prior research has shown that English learner (EL) classification is consequential for students; however, less is known about how EL classification affects student outcomes. In this study, we examine one hypothesized mechanism: teacher perceptions. Using a national data set (Early Childhood Longitudinal Study--Kindergarten Cohort of 2010-2011 or…
