Democratic Policymaking in Schools: The Influence of Teacher Empowerment on Student Achievement
Despite the popularity of teacher leadership since the 1980s, little research examines its effects on student achievement. In this paper, I assess the influence of the New York City Department of Education’s Teacher Career Pathways program, a teacher leadership initiative, on student achievement… more →
Accelerating Opportunity: The Effects of Instructionally Supported Detracking
The pivotal role of Algebra in the educational trajectories of U.S. students continues to motivate controversial, high-profile policies focused on when students access the course, their classroom peers, and how the course is taught. This random-assignment partnership study examines an innovative… more →
Loss of Schooling from Tropical Cyclones: Evidence from 13 Low- and Middle-income Countries
Increasing educational attainment is one of the most important and effective tools for health and economic improvements. The extent to which extreme climate events disrupt education, resulting in fewer years of schooling and reduced educational attainment, remains under-studied. Children in low… more →
The Effect of Student-Tutor Ratios: Experimental Evidence from a Pilot Online Math Tutoring Program
Budget constraints and limited supplies of local tutors have caused many K-12 school districts to pivot from individual tutoring in-person toward small-group tutoring online to expand access to personalized instruction. We conduct a field experiment to explore the effect of increasing student-… more →
The Effects of Virtual Tutoring on Young Readers: Results from a Randomized Controlled Trial
In-person tutoring has been shown to improve academic achievement. Though less well-researched, virtual tutoring has also shown a positive effect on achievement but has only been studied in grade five or above. We present findings from the first randomized controlled trial of virtual tutoring… more →
The relationship between student attendance and achievement, pre- and post-COVID
We examine the relationship between absenteeism and achievement since the onset of COVID-19. Applying first-differences models to North Carolina administrative data, we estimate that each absence was associated with a 0.0032 standard deviation (SD) decline in math achievement in 2022-23. As… more →
The Prevalence and Policy Implications of Between-School Heterogeneity in Learning Outcomes: Evidence from Six Public Education Systems
While learning outcomes in low- and middle-income countries are generally at low levels, the degree to which students and schools more broadly within education systems lag behind grade-level proficiency can vary significantly. A substantial portion of existing literature advocates for aligning… more →
Label to Help: The Effects of Special Education on Student Outcomes
This study examines the impact of special education on academic and behavioral outcomes for students with learning disabilities (LD) by using statewide Indiana data covering kindergarten through eighth grade. The results from student fixed effects models show that special education services… more →
Can Computer-Assisted Instruction Help Schools to Close the Achievement Gap: Evaluation of a District-Wide Reading Intervention
A concerning number of middle and high school students lack fundamental reading skills in the United States. One common way schools address this issue is by supporting those students with computer-assisted instruction. This study evaluates the causal effect of one such computer-assisted… more →
How Early Morning Classes Change Academic Trajectories: Evidence from a Natural Experiment
Using a natural experiment which randomized class times to students, this study reveals that enrolling in early morning classes lowers students' course grades and the likelihood of future STEM course enrollment. There is a 79% reduction in pursuing the corresponding major and a 26% rise in… more →
Attendance Practices in High-Absenteeism Districts
Educational policymakers, leaders, and researchers are paying increasing attention to student attendance and chronic absenteeism, especially in the wake of the COVID-19 pandemic. Though researchers have documented the consequences and causes of absenteeism, there is limited empirical evidence… more →
Sustained Effects of Small-Group Instruction in Mathematics
Recent research suggests that using additional teachers to provide small-group instruction or tutoring substantially improves student learning. However, treatment effects on test scores can fade over time, and less is known about the lasting effects of such interventions. We leverage data from a… more →
Exploring Multidimensional Approaches to Learning During Early Childhood in Ghana
Children's approaches to learning (AtL) are widely recognized as a critical predictor of educational outcomes, especially in early childhood. Nevertheless, there remains a dearth of understanding regarding the dimensionality of AtL, the reciprocal dynamics between AtL and learning outcomes, and… more →
Scaling High-impact tutoring: School Level Perspectives on Implementation Challenges and Strategies
High-impact tutoring has emerged as a primary school district investment for addressing learning loss that occurred during the COVID-19 pandemic. While existing research shows that high-impact tutoring is effective for accelerating student learning, this study examined the school-level… more →
Transitional Kindergarten: The New Kid on the Early Learning Block
In recent years, several states have expanded a new publicly funded learning option: Transitional Kindergarten (TK). TK programs bridge prekindergarten and kindergarten in their eligibility, requirements, and design. We use Michigan’s TK program as a case study on the fit of this new entrant in… more →
The Effect of Early Childhood Programs on Third-Grade Test Scores: Evidence from Transitional Kindergarten in Michigan
Transitional Kindergarten (TK) is a relatively recent entrant into the U.S. early education landscape, combining features of public pre-K and regular kindergarten. We provide the first estimates of the impact of Michigan’s TK program on 3rd grade test scores. Using an augmented regression… more →
Under the Weather? The Effects of Temperature on Student Test Performance
As students are exposed to extreme temperatures with ever-increasing frequency, it is important to understand how such exposure affects student learning. In this paper we draw upon detailed student achievement data, combined with high-resolution weather records, to paint a clear portrait of the… more →
COVID-19, School Closures, and Student Learning Outcomes: New Global Evidence from PISA
The COVID-19 pandemic resulted in significant disruption in schooling worldwide. This paper uses global test score data to estimate learning losses. It models the effect of school closures on achievement by predicting the deviation of the most recent results from a linear trend using data from… more →
The Ups and Downs of Classroom Quality Over the Preschool Year and Relations to Children’s School Readiness
Despite considerable evidence on the links between average classroom quality and children’s learning, the importance of variation in quality is not well understood. We examined whether three measures of variation in observed classroom quality over the school year – overall variation in quality,… more →
A Scalable Approach to High-Impact Tutoring for Young Readers: Results of a Randomized Controlled Trial
This paper presents the results from a randomized controlled trial of Chapter One, an early elementary reading tutoring program that embeds part-time tutors into the classroom to provide short bursts of 1:1 instruction. Eligible kindergarten students were randomly assigned to receive… more →
