The Big Problem with Little Interruptions to Classroom Learning
Narrative accounts of classroom instruction suggest that external interruptions, such as intercom announcements and visits from staff, are a regular occurrence in U.S. public schools. We study the frequency, nature, and duration of external interruptions in the Providence Public School District… more →
Projecting the potential impacts of COVID-19 school closures on academic achievement
With 55 million students in the United States out of school due to the COVID-19 pandemic, education systems are scrambling to meet the needs of schools and families, including planning how best to approach instruction in the fall given students may be farther… more →
School Segregation At The Classroom Level In A Southern 'New Destination' State
Using detailed administrative data for public schools, we document racial and ethnic segregation at the classroom level in North Carolina, a state that has experienced a sharp increase in Hispanic enrollment. We decompose classroom-level segregation in counties into within-school and between-… more →
Pre-Service Teacher Quality and Workforce Entry
Using rich longitudinal data from one of the largest teacher education programs in Texas, we examine the measurement of pre-service teacher (PST) quality and its relationship with entry into the K–12 public school teacher workforce. Drawing on rubric-based observations of PSTs during clinical… more →
The effects of English language development curriculum materials on students’ English proficiency
Castañeda v. Pickard (1981) mandated that educational programs for emergent bilinguals be tested for program efficacy. Since English language development (ELD) curricular materials are one part of an instructional program, we assess this mandate by examining the effectiveness of ELD materials in… 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 →
Targeted Interventions in High School: Preparing Students for College
This study adds to the currently limited evidence base on the efficacy of interventions targeting non-college-ready high school students by examining the impact of Kentucky’s Targeted Interventions (TI) program. We focus on interventions that students received under TI in the senior year of high… more →
Examining the Educational Spillover Effects of Severe Natural Disasters: The Case of Hurricane Maria
This study examines the effects of internal migration driven by severe natural disasters on host communities, and the mechanisms behind these effects, using the large influx of migrants into Florida public schools after Hurricane Maria. I find adverse effects of the influx in the first year on… more →
Getting Tough? The Effects of Discretionary Principal Discipline on Student Outcomes
Nationwide, school principals are given wide discretion to use disciplinary tools like suspension and expulsion to create a safe learning environment. There is legitimate concern that this power can have negative consequences, particularly for the students who are excluded. This study uses… more →
More Than Shortages: The Unequal Distribution of Substitute Teaching
Classroom teachers in the US are absent on average approximately six percent of a school year. Despite the prevalence of teacher absences, surprisingly little research has assessed the key source of replacement instruction: substitute teachers. Using detailed administrative and survey data from… more →
Does the Common Core Have a Common Effect?: An Exploration of Effects on Academically Vulnerable Students
Policymakers have sought to increase the rigor of content standards since the 1990s. However, the literature examining the effects of reforms to content standards on student outcomes is still developing. This study examines the extent to which the Common Core State Content Standards (CC)… more →
Unequal Pay for Equal Work? Unpacking the Gender Gap in Principal Compensation
We investigate the male–female gap in principal compensation in state and national data: detailed longitudinal personnel records from the state of Missouri and repeated cross-sections from the nationally representative Schools and Staffing Survey (SASS). In both data sets, we estimate… more →
Is the Rise of High School Graduation Rates Real? High-Stakes School Accountability and Strategic Behavior
High school graduation rates have increased dramatically in the past two decades. Some skepticism has arisen, however, because of the confluence of the graduation rise and the starts of high-stakes accountability for graduation rates with No Child Left Behind (NCLB). In this study we provide… more →
Year-Round School Calendars: Effects on Summer Learning, Achievement, Parents, Teachers, and Property Values
Year-round school calendars take the usual 175-180 instruction days of the school year and redistribute them, replacing the usual schedule – nine months on, three months off – with a more “balanced” schedule of short instruction periods alternating with shorter breaks across all four seasons of… 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 →
Is kindergarten ability group placement biased? New data, new methods, new answers
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… more →
Impacts of School Entry Age on Academic Growth through 2nd Grade: A Multi-State Regression Discontinuity Analysis
The belief that additional time allows children to become more ready for school has affected public policy and individual practices. Prior studies estimated either associations between school entry age and academic growth or causal effects on achievement measured at one or two points. This paper… more →
Preferences, Selection, and the Structure of Teacher Pay
Human-capital formation in school depends largely on the selection and retention of teachers. I conduct a discrete-choice experiment with responses linked to administrative teacher and student records to examine teacher preferences for compensation structure and working conditions. I calculate… more →
Testing, Teacher Turnover and the Distribution of Teachers Across Grades and Schools
Teacher turnover has adverse consequences for student achievement and imposes large financial costs for schools. Some have argued that high-stakes testing may lower teachers’ satisfaction with their jobs and could be a major contributor to teacher attrition. In this paper, we exploit changes in… more →
