The Impacts of Schools on Racial Attitudes, Prosocial Behaviors, and Sociopolitical Preferences

Descriptive and causal evidence on families' longitudinal preferences for schools

Draft available upon request.

Abstract:
I investigate longitudinal preferences for schools revealed by families’ top choices for middle and high schools in applications to a large urban school district’s universal enrollment system. Using this unique dataset, I find preferences for the racial/ethnic composition of schools’ students to be more stable than preferences for school quality and proximity to home. Using experimental variation generated by the random assignment of students to oversubscribed schools, I find that assigned middle school proximity, but not racial/ethnic composition or quality, has a causal effect on families’ preferences for high schools with the same attributes. Because families’ preferences do not appear malleable, increasing enrollment at high quality schools and decreasing school segregation may be hard to achieve through school choice policies.

The impact of school desegregation on White individuals' racial attitudes and politics in adulthood.

Draft available upon request.

Abstract:
In this paper I study how school desegregation by race following
Brown v. Board of Education affected White individuals’ racial attitudes and politics in adulthood. I use geocoded nationwide data from the General Social Survey and differences-in-differences to identify causal impacts. Integration significantly reduced White individuals’ political conservatism as adults in the U.S. South but not elsewhere. A similar but weaker pattern emerges for individuals’ attitudes towards Blacks and policies promoting racial equity. Results suggest that heterogeneity depends on the effectiveness of integration policies. In the south, Black-White exposure was greater following desegregation, and White disenrollment was lower. My study thus provides the first causal evidence supporting the contact hypothesis working in schools following historic court mandates to desegregate.

Abstract:
In this paper I study the impact of court-mandated school desegregation by race on student suspensions and special education classification. Simple descriptive statistics using student enrollment and outcome data collected from the largest school districts across the country in the 1970s and 1980s show that Black-White school integration was increasing for districts under court order, but not for a set of comparison districts. Similarly, Black student suspension rates were increasing at faster rates in integrating districts relative to comparison districts, and their classification rates as having an intellectual disability were decreasing at slower rates. Differences-in-differences and event study models confirm these patterns I observe in the raw data: after integration, school districts experienced statistically and practically significant reductions in racial isolation across schools and growth in racial disparities in discipline and special education classification. The impacts of integration are immediate, sustained, and robust for student suspensions in particular. My results thus provide causal evidence confirming prior descriptive and theoretical work suggesting that the racial composition of schools may influence measures of categorical inequality by race.

The impact of political party control on education finance and outcomes: Evidence from U.S. states. (with Lena Shi)

Abstract:
Given states’ balanced budget requirements, investment decisions often involve trade-offs between policymakers’ budget priorities. Does political party control affect investment decisions and outcomes? Using a regression discontinuity design based on close state elections between 1984-2013, we find that marginally Democratic legislatures spend more on higher education but less on K-12 education. Rather than trading off within the education budget, policymakers trade education and welfare, particularly in liberal and high-poverty states. Increases in local revenue offset party differences in K-12 spending, suggesting that policymakers make trade-offs by considering the availability of external budget sources and how investments respond to constituents’ needs.

Bias in the air: A nationwide exploration of teachers' implicit racial attitudes, aggregate bias, and student outcomes. (with Dave Quinn, Tasminda Dhaliwal, and Virginia Lovison)

Abstract:
Theory suggests that teachers’ implicit racial attitudes affect their students, but large-scale evidence on U.S. teachers’ implicit biases and their correlates is lacking. Using nationwide data from Project Implicit, we found that teachers’ implicit White/Black biases (as measured by the implicit association test) vary by teacher gender and race. Teachers’ adjusted bias levels are lower in counties with larger shares of Black students. In the aggregate, counties in which teachers hold higher levels of implicit and explicit racial bias have larger adjusted White/Black test score inequalities and White/Black suspension disparities.

Pre-print.

Abstract: English learners’ (ELs) day-to-day experiences in school change when reclassified as fully English proficient. Prior research, however, is mixed on how reclassification influences outcomes. Many studies also do not or cannot explore key long-term outcomes or identify impacts over time. In this study I leverage longitudinal student data in a regression discontinuity and find that reclassification after third grade affects ELs’ achievement in the short and longer term. Reclassified ELs score considerably higher on mathematics and reading standardized tests in fifth and eighth grade. I also provide the first causal evidence for the impact of reclassification on several theoretically affected noncognitive outcomes. I find that reclassification substantially lowers the level of challenge for work assigned by teachers and increases ELs’ out-of-school engagement in the short term. However, effects on noncognitive outcomes attenuate or reverse direction in the longer term. Together, these findings highlight the need for evaluations to consider multiple measures and to identify impacts over time when possible, especially when data on long-term outcomes such as high school graduation, college persistence, or labor market success are unavailable.

School district reform in Newark: Within- and Between-school changes in achievement growth. (with Tom Kane, Whitney Kozakowski, Beth Schueler, and Doug Staiger)

NBER Working Paper.

Abstract:
In the 2011–12 school year, the Newark Public School district (NPS) launched a set of educational reforms supported by a gift from Facebook CEO Mark Zuckerberg and Priscilla Chan. Using data from 2008–09 through 2015–16, the authors evaluate the change in Newark students’ achievement growth relative to similar students and schools elsewhere in New Jersey. They measure achievement growth using a “value-added” model, controlling for prior achievement, demographics, and peer characteristics. By the fifth year of reform, Newark saw statistically significant gains in English language arts (ELA) achievement growth and no significant change in math achievement growth. Perhaps because of the disruptive nature of the reforms, growth declined initially before rebounding in later years. Much of the improvement was attributed to shifting enrollment from lower- to higher-growth district and charter schools.

Teacher and Teaching Quality

An experimental evaluation of three teacher quality measures: Value-added, classroom observations, and student surveys. (with Andrew Bacher-Hicks, Tom Kane, and Doug Staiger)

Abstract:
Nearly every state evaluates teacher performance using multiple measures, but evidence has largely shown that only one such measure—teachers’ effects on student achievement (i.e., value-added)—captures teachers’ causal effects. We conducted a random assignment experiment in 66 fourth- and fifth-grade mathematics classrooms to evaluate the predictive validity of three measures of teacher performance: value-added, classroom observations, and student surveys. Combining our results with those from two previous random assignment experiments, we provide additional experimental evidence that value-added measures are unbiased predictors of teacher performance. Though results for the other two measures are less precise, we find that classroom observation scores are predictive of teachers’ performance after random assignment while student surveys are not. These results thus lend support to teacher evaluation systems that use value-added and classroom observations, but suggest practitioners should proceed with caution when considering student survey measures for teacher evaluation.
