Who Benefits from Local Financing of Public Services? A Causal Analysis
The efficiency-equity trade-offs in public service delivery may be influenced by the dependency of local governments on their own resources rather than inter-governmental grants. School districts in the United States are expected both to produce human capital efficiently and to provide… more →
Status, Growth, and Perceptions of School Quality
States and districts are increasingly incorporating measures of achievement growth into their school accountability systems, but there is little research on how these changes affect the public’s perceptions of school quality. We conduct a nationally representative online survey experiment to… more →
The Design of Clustered Observational Studies in Education
Clustered observational studies (COSs) are a critical analytic tool for educational effectiveness research. We present a design framework for the development and critique of COSs. The framework is built on the counterfactual model for causal inference and promotes the concept of… more →
Matching Methods for Clustered Observational Studies in Education
Many interventions in education occur in settings where treatments are applied to groups. For example, a reading intervention may be implemented for all students in some schools and withheld from students in other schools. When such treatments are non-randomly allocated, outcomes across the… more →
O Brother, Where Start Thou? Sibling Spillovers on College and Major Choice in Four Countries
Family and social networks are widely believed to influence important life decisions but identifying their causal effects is notoriously difficult. Using admissions thresholds that directly affect older but not younger siblings’ college options, we present evidence from the United States, Chile,… more →
Experimentally Estimated Impacts of School Vouchers on Educational Attainments of Moderately and Severely Disadvantaged Students
Although qualitative research suggests that school choice and other interventions are more beneficial for moderately disadvantaged than severely deprived students, the subject has barely been explored by quantitative studies with either observational or experimental designs. We estimate… more →
Long-run Trends in the U.S. SES-Achievement Gap
Rising inequality in the United States has raised concerns about potentially widening gaps in educational achievement by socio-economic status (SES). Using assessments from LTT-NAEP, Main-NAEP, TIMSS, and PISA that are psychometrically linked over time, we trace trends in achievement for U.S.… more →
Bias in the Air: A Nationwide Exploration of Teachers' Implicit Racial Attitudes, Aggregate Bias, and Student Outcomes
Theory suggests that teachers’ implicit racial attitudes affect their students, but we lack large-scale evidence on US teachers’ implicit biases and their correlates. Using nationwide data from Project Implicit, we find that teachers’ implicit White/Black biases (as measured by the implicit… more →
Shifting Alliances in State Political Parties: The Case of Education Interest Groups
Political parties in the U.S. are composed of networks of interest groups, according to the extended party network theory. Scholars have focused on national extended party networks. We use the case of education interest groups to explore how policy environments shape party networks on the state… more →
O Brother, Where Start Thou? Sibling Spillovers in College Enrollment
We study within-family spillovers in college enrollment to show college-going behavior is transmissible between peers. Because siblings’ test scores are weakly correlated, we exploit college-specific admissions thresholds that directly affect older but not younger siblings’ college options. Older… more →
The Effects of Student Growth Data on School District Choice: Evidence from a Survey Experiment
We conduct an online survey experiment in which participants are asked to imagine that they are parents moving to a new metropolitan area. They then choose between the five largest school districts in that area. All participants receive demographic data for each district. In addition, some… more →
Strengthening STEM Instruction in Schools: Learning from Research
More than half of U.S. children fail to meet proficiency standards in mathematics and science in fourth grade. Teacher professional development and curriculum improvement are two of the primary levers that school leaders and policymakers use to improve children’s science, technology, engineering… more →
Teacher peer observation and student test scores: Evidence from a field experiment in English secondary schools
This paper reports improvements in teacher job performance, as measured by student test scores, resulting from a program of (zero-) low-stakes peer evaluation. Teachers working at the same school observed and scored each other’s teaching. Students in randomly-assigned treatment schools scored 0… more →
STEM Instruction Improvement Programs Improve Student Outcomes
How should teachers spend their STEM-focused professional learning time? To answer this question, we analyzed a recent wave of rigorous new studies of STEM instructional improvement programs. We found that programs work best when focused on building knowledge teachers can use during instruction:… more →
Can Information Widen Socioeconomic Gaps in Postsecondary Aspirations? How College Costs and Returns Affect Parents’ Preferences for their Children
To estimate whether information can close socioeconomic gaps in parents’ aspirations for their child’s postsecondary education, we administer a four-armed survey experiment to a nationally representative sample of U.S. parents. After respondents estimate costs of and returns to further education… more →
Federalism, Race, and the Politics of Turnaround: U.S. Public Opinion on Improving Low-Performing Schools and Districts
Public support for school improvement policies can increase the success and durability of those reforms. However, little is known about public views on turnaround. We deployed questions and embedded experiments in a nationally representative 2017 survey (n=4,214) to uncover opinions regarding (a… more →
Developing Ambitious Mathematics Instruction Through Web-Based Coaching: A Randomized Field Trial
This paper describes and evaluates a web-based coaching program designed to support teachers in implementing Common Core-aligned math instruction. Web-based coaching programs can be operated at relatively lower costs, are scalable, and make it more feasible to pair teachers with coaches who have… more →
Teacher Skill Development: Evidence from Performance Ratings by Principals
We examine the dynamic nature of teacher skill development using panel data on principals’ subjective performance ratings of teachers. Past research on teacher productivity improvement has focused primarily on one important but narrow measure of performance: teachers’ value-added to student… more →
Experimentally Estimated Impacts of School Voucher on Educational Attainments of Moderately and Severely Disadvantaged Students
Estimates of school voucher impacts on educational attainment have yet to explore heterogeneities in socioeconomic status among disadvantaged minority students. We theorize reasons for these heterogeneities and then estimate experimentally the differential impacts of voucher offers on college… more →
Making a Match: How Successful High-Poverty Schools Hire Teachers
Effective teacher hiring is fundamental to improving schools and yet few studies investigate this process. In this exploratory study of six successful, high-poverty schools (three charter, three district) in one Massachusetts city, we analyze the policy contexts that influenced hiring and… more →
