Using Gaussian Process Regression in Two-Dimensional Regression Discontinuity Designs
Sometimes a treatment, such as receiving a high school diploma, is assigned to students if their scores on two inputs (e.g., math and English test scores) are above established cutoffs. This forms a multidimensional regression discontinuity design (RDD) to analyze the effect of the educational… more →
Do the Effects Persist? An Examination of Long-term Effects After Students Leave Turnaround Schools
Whole-school reforms have received widespread attention, but a critical limitation of the current literature is the lack of evidence around whether these extensive and costly interventions improve students’ long-term outcomes after they leave reform schools. Leveraging Tennessee’s statewide… more →
Career Sequences and Unequal Sorting of Subject Area Teachers along the Path to the Principalship
The path to becoming a school principal is characterized by a variety of trajectories that reflect the diverse experiences and backgrounds of aspiring leaders. While ideally the road to the principalship would result in a proportional and representative body of principals, research has shown… more →
Applying to Lead: A Mixed-Methods Investigation of Prospective Principals’ Job Application Strategies in Two Urban Districts
Purpose: Urban school districts often face challenges in filling principal vacancies with effective leaders, especially in high-needs schools. Prospective principals’ engagement with the job application process may contribute to these challenges. The goal of this study is to… more →
Teaching Teachers to Use Computer Assisted Learning Effectively: Experimental and Quasi-Experimental Evidence
Mastery learning – the process by which students must demonstrate proficiency with a single topic before moving on – is well recognized as one of the best ways to learn, yet many teachers struggle or remain unsure about how to implement it into a classroom setting. This study leverages two field… more →
Less is More: The Causal Effect of Four-Day School Weeks on Employee Turnover
The use of four-day school weeks (4dsw) in the United States has expanded rapidly over the past two decades. Previous work examines the impact of 4dsw on student outcomes, but little research to date examines the effect on school employees even though schools in some locales have adopted 4dsw to… more →
Untapped Potential? Understanding the Paraeducator-to-Teacher Pipeline and its Potential for Diversifying the Teacher Workforce
Paraeducators are among the largest categories of public education employees and are increasingly seen as a pool of potential teachers. However, little is known about paraeducator-to-teacher transitions. Using statewide administrative data, we show that while paraeducators may be more racially/… more →
The Causes and Consequences of U.S. Teacher Strikes
The U.S. has witnessed a resurgence of labor activism, with teachers at the forefront. We examine how teacher strikes affect compensation, working conditions, and productivity with an original dataset of 772 teacher strikes generating 48 million student days idle between 2007 and 2023. Using an… more →
What Impacts Should We Expect from Tutoring at Scale? Exploring Meta-Analytic Generalizability
U.S. public schools are engaged in an unprecedented effort to expand tutoring in the wake of the pandemic. Broad-based support for scaling tutoring emerged, in part, because of the large effects on student achievement found in prior meta-analyses. We conduct an expanded meta-analysis of 282… more →
The Scaling Dynamics and Causal Effects of a District-Operated Tutoring Program
Public school systems across the U.S. have made major investments in tutoring to support students’ academic recovery in the wake of the COVID-19 pandemic. We evaluate a large urban district’s efforts to design, implement, and scale a district-operated, standards-based tutoring program across… more →
A Quantitative Study of Mathematical Language in Upper Elementary Classrooms
This study provides the first large-scale quantitative exploration of mathematical language use in upper elementary U.S. classrooms. Our approach employs natural language processing techniques to describe variation in teachers’ and students’ use of mathematical language in 1,657 fourth and fifth… more →
Scaffolding Middle-School Mathematics Curricula With Large Language Models
Despite well-designed curriculum materials, teachers often face challenges in their implementation due to diverse classroom needs. This paper investigates whether Large Language Models (LLMs) can support middle-school math teachers by helping create high-quality curriculum scaffolds, which we… more →
Charter School Expansion, Catholic School Enrollment, & the Equity Implications of School Choice
Catholic schools have seen more than a 30% decline in enrollment over the past 20 years. While some of the decline in enrollment may have been spurred by secular trends or the Church abuse scandal, the increase in schools of choice, principally public charter schools, may explain at least some… more →
Early Life Health Conditions and Racial Gaps in Education
Racial disparities in infant health conditions have persisted for decades. However, there is surprisingly limited evidence regarding the long-term consequences of these disparities. Using novel linked administrative data from Texas and the shift to Medicaid Managed Care (MMC), I show that MMC-… more →
The Racial Gap in Friendships Among High-Achieving Students
High-achieving minority students have fewer friends than their majority counterparts. Exploring patterns of friendship formation in the Add Health data, we find strong racial homophily in friendship formations as well as strong achievement homophily within race. However, we find that achievement… more →
STEM teacher workforce in high-need schools resilient despite shrinking supply and increasing demand
The teacher workforce in science, technology, engineering, and math (STEM) has been a perpetual weak spot in public schools’ teaching rosters. Prior reports show the pipeline of new STEM teachers into the profession is weak while demand for instruction in STEM fields continues to grow. This… more →
A Meta-Analysis of the Experimental Evidence Linking Mathematics and Science Professional Development Interventions to Teacher Knowledge, Classroom Instruction, and Student Achievement
Despite evidence that teacher professional development interventions in mathematics and science can increase student achievement, our understanding of the mechanisms by which this occurs – particularly how these interventions affect teachers themselves, and whether teacher-level changes predict… more →
Structured Reporting Guidelines for Classroom Intervention Research
Inconsistent reporting of critical facets of classroom interventions and their related impact evaluations hinders the field’s ability to describe and synthesize the existing evidence base. In this essay, we present a set of reporting guidelines intended to steer authors of classroom intervention… more →
Did COVID-19 Shift the “Grammar of Schooling”?
The immediate impacts of COVID-19 on K12 schooling are well known. Over nearly 18 months, students’ academic performance and mental health deteriorated dramatically. This study aims to identify if and how the pandemic led to longer-term changes in core aspects of schooling.
The Lasting Effects of the COVID-19 Pandemic on K-12 Schooling: Evidence from a Nationally Representative Teacher Survey
This paper reports findings from a nationally representative survey of K-12 teachers in May 2023 that examines the potential long-term impacts of COVID-19 on public schooling. The findings suggest fundamental ways in which school operations, instructional practice and parent-teacher interaction… more →
