School Discipline and Racial Disparities in Early Adulthood.

Despite interest in the contributions of school discipline to the creation of racial inequality, previous research has been unable to identify how students who receive suspensions in school differ from unsuspended classmates on key young adult outcomes. We utilize novel data to document the links between high school discipline and important young adult outcomes related to criminal justice contact, social safety net program participation, post-secondary education, and the labor market. We show that the link between school discipline and young adult outcomes tends to be stronger for Black students than for White students, and that approximately 30 percent of the Black-White disparities in young adult criminal justice outcomes, SNAP receipt, and college completion can be traced back to inequalities in exposure to school discipline.

Ethnic studies increases longer-run academic engagement and attainment.

Increased interest in anti-racist education has motivated the rapidly growing but politically contentious adoption of ethnic studies (ES) courses in US public schools. A long-standing rationale for ES courses is that their emphasis on culturally relevant and critically engaged content (e.g., social justice, anti-racism, stereotypes, contemporary social movements) has potent effects on student engagement and outcomes. However, the quantitative evidence supporting this claim is limited. In this preregistered regression-discontinuity study, we examine the longer-run impact of a grade 9 ES course offered in the San Francisco Unified School District. Our key confirmatory finding is that assignment to this course significantly increased the probability of high school graduation among students near the grade 8 2.0 grade point average (GPA) threshold used for assigning students to the course. Our exploratory analyses also indicate that assignment increased measures of engagement throughout high school (e.g., attendance) as well as the probability of postsecondary matriculation.

Teacher Effects on Student Achievement and Height: A Cautionary Tale.

We apply "value-added" models to estimate the effects of teachers on an outcome they cannot plausibly affect: student height. When fitting commonly estimated models to New York City data, we find that the standard deviation of teacher effects on height is nearly as large as that for math and reading, raising potential concerns about value-added estimates of teacher effectiveness. We consider two explanations: non-random sorting of students to teachers and idiosyncratic classroom-level variation. We cannot rule out sorting on unobservables, but find students are not sorted to teachers based on lagged height. The correlation in teacher effects estimates on height across years and the correlation between teacher effects on height and teacher effects on achievement are insignificant. The large estimated "effects" for height appear to be driven by year-to-year classroom by teacher variation that is not often separable from true effects in models commonly estimated in practice. Reassuringly for use of these models in research settings, models which disentangle persistent effects from transient classroom-level variation yield the theoretically expected effects of zero for teacher value added on height.

Differing Views of Equity: How Prospective Educators Perceive Their Role in Closing Achievement Gaps.

Hiring is an opportunity for school districts to find educators with values and beliefs that align with district goals. Yet beliefs are difficult to measure. We use administrative data from more than ten thousand applications to certificated positions in an urban California school district in which applicants submitted essays about closing achievement gaps. Using structural topic modeling (STM) to code these essays, we examine whether applicants systematically differ in their use of these themes and whether themes predict hiring outcomes. Relative to white applicants, Hispanic and African American applicants are more likely to identify structural causes of inequities and discuss educators' responsibilities for addressing inequality. Similar differences in themes emerge between applicants to schools with different student populations. Techniques like STM can decipher hard-to-measure beliefs from administrative data, providing valuable information for hiring and decision making.

Early Parenting and the Reduction of Educational Inequality in Childhood and Adolescence.

Socio-economic status (SES) differences in parenting are often implicated in widening the SES-achievement gap. Using nationally representative data (N = 12,887), this study tests for variation across SES in the types and intensity of parenting behaviors utilized and then examines SES differences in the relationship between parenting and student achievement growth from kindergarten through eighth grade. Exploratory factor analysis identifies three dimensions of early parenting: Educational Engagement, Stimulating Parent-Child Interaction, and Discursive Discipline. Regression results indicate that all three dimensions are used most heavily by high-SES families. However, only Educational Engagement consistently predicts achievement growth. Surprisingly, it is positively associated with achievement for lower-, but not higher-SES students in first through eighth grades. Further, Educational Engagement is beneficial for low-SES children because it is particularly beneficial for low-achieving students, consistent with a compensatory hypothesis.

Categorical Inequality: Schools As Sorting Machines.

Despite their egalitarian ethos, schools are social sorting machines, creating categories that serve as the foundation of later life inequalities. In this review, we apply the theory of categorical inequality to education, focusing particularly on contemporary American schools. We discuss the range of categories that schools create, adopt, and reinforce, as well as the mechanisms through which these categories contribute to production of inequalities within schools and beyond. We argue that this categorical inequality frame helps to resolve a fundamental tension in the sociology of education and inequality, shedding light on how schools can-at once-be egalitarian institutions and agents of inequality. By applying the notion of categorical inequality to schools, we provide a set of conceptual tools that can help researchers understand, measure, and evaluate the ways in which schools structure social inequality.

Teaching for All? Teach For America's Effects across the Distribution of Student Achievement.

This paper examines the effect of Teach For America (TFA) on the distribution of student achievement in elementary school. It extends previous research by estimating quantile treatment effects (QTE) to examine how student achievement in TFA and non-TFA classrooms differs across the broader distribution of student achievement. It also updates prior distributional work on TFA by correcting for previously unidentified missing data and estimating unconditional, rather than conditional QTE. Consistent with previous findings, results reveal a positive impact of TFA teachers across the distribution of math achievement. In reading, however, relative to veteran non-TFA teachers, students at the bottom of the reading distribution score worse in TFA classrooms, and students in the upper half of the distribution perform better.

`Membership Has Its Privileges': Status Incentives and Categorical Inequality in Education.

Prizes - formal systems that publicly allocate rewards for exemplary behavior - play an increasingly important role in a wide array of social settings, including education. In this paper, we evaluate a prize system designed to boost achievement at two high schools by assigning students color-coded ID cards based on a previously low stakes test. Average student achievement on this test increased in the ID card schools beyond what one would expect from contemporaneous changes in neighboring schools. However, regression discontinuity analyses indicate that the program created new inequalities between students who received low-status and high-status ID cards. These findings indicate that status-based incentives create categorical inequalities between prize winners and others even as they reorient behavior toward the goals they reward.

Distributional Analysis in Educational Evaluation: A Case Study from the New York City Voucher Program.

We use quantile treatment effects estimation to examine the consequences of the random-assignment New York City School Choice Scholarship Program (NYCSCSP) across the distribution of student achievement. Our analyses suggest that the program had negligible and statistically insignificant effects across the skill distribution. In addition to contributing to the literature on school choice, the paper illustrates several ways in which distributional effects estimation can enrich educational research: First, we demonstrate that moving beyond a focus on mean effects estimation makes it possible to generate and test new hypotheses about the heterogeneity of educational treatment effects that speak to the justification for many interventions. Second, we demonstrate that distributional effects can uncover issues even with well-studied datasets by forcing analysts to view their data in new ways. Finally, such estimates highlight where in the overall national achievement distribution test scores of children exposed to particular interventions lie; this is important for exploring the external validity of the intervention's effects.

Curricular policy as a collective effects problem: A distributional approach.

Current educational policies in the United States attempt to boost student achievement and promote equality by intensifying the curriculum and exposing students to more advanced coursework. This paper investigates the relationship between one such effort - California's push to enroll all 8th grade students in Algebra - and the distribution of student achievement. We suggest that this effort is an instance of a "collective effects" problem, where the population-level effects of a policy are different from its effects at the individual level. In such contexts, we argue that it is important to consider broader population effects as well as the difference between "treated" and "untreated" individuals. To do so, we present differences in inverse propensity score weighted distributions investigating how this curricular policy changed the distribution of student achievement. We find that California's attempt to intensify the curriculum did not raise test scores at the bottom of the distribution, but did lower scores at the top of the distribution. These results highlight the efficacy of inverse propensity score weighting approaches for examining distributional differences, and provide a cautionary tale for curricular intensification efforts and other policies with collective effects.

The Effect of Baby Books on Mothers' Reading Beliefs and Reading Practices.

The impact of a baby book intervention on promoting positive reading beliefs and increasing reading frequency for low-income, new mothers (n = 167) was examined. The Baby Books Project randomly assigned low-income, first-time mothers to one of three study conditions, receiving educational books, non-educational books, or no books, during pregnancy and over the first year of parenthood. Home-based data collection occurred through pregnancy until 18 months post-partum. Mothers who received free baby books had higher beliefs about the importance of reading, the value of having resources to support reading, and the importance of verbal participation during reading. The results showed that providing any type of baby books to mothers positively influenced maternal reading beliefs, but did not increase infant-mother reading practices. Maternal reading beliefs across all three groups were significantly associated with self-reported reading frequency when children were at least 12 months of age.

Algebra for All: California's Eighth-Grade Algebra Initiative as Constrained Curricula.

BACKGROUND/CONTEXT: Across the United States, secondary school curricula are intensifying as a growing proportion of students enroll in high-level academic math courses. In many districts, this intensification process occurs as early as eighth grade, where schools are effectively constraining their mathematics curricula by restricting course offerings and placing more students into Algebra I. This paper provides a quantitative single-case research study of policy-driven curricular intensification in one California school district. RESEARCH QUESTIONS: (1a) What effect did 8th eighth grade curricular intensification have on mathematics course enrollment patterns in Towering Pines Unified schools? (2b) How did the distribution of prior achievement in Towering Pines math classrooms change as the district constrained the curriculum by universalizing 8th eighth grade Algebra? (3c) Did 8th eighth grade curricular intensification improve students' mathematics achievement? SETTING: Towering Pines is an immigrant enclave in the inner-ring suburbs of a major metropolitan area. The district's 10 middle schools together enroll approximately 4,000 eighth graders each year. The districts' students are ethnically diverse and largely economically disadvantaged. The study draws upon administrative data describing 8th eighth graders in the district in the 2004-20-05 through 2007-20-08 school years. INTERVENTION/PROGRAM/PRACTICE: During the study period, Towering Pines dramatically intensified middle school students' math curricula: In the 2004-20-05 school year 32% of the district's 8th eighth graders enrolled in Algebra or a higher- level mathematics course; by the 2007-20-08 school year that proportion had increased to 84%. RESEARCH DESIGN: We use an interrupted time-series design, comparing students' 8th eighth grade math course enrollments, 10th grade math course enrollments, and 10th grade math test scores across the four cohorts, controlling for demographics and prior achievement. FINDINGS/RESULTS: We find that students' odds of taking higher level mathematics courses increased as this district implemented the state's Algebra mandate. However, even as the district implemented a constrained curriculum strategy, mathematics achievement growth between 6th sixth and 10th grade slowed and the achievement advantages associated with 8th eighth grade Algebra declined. CONCLUSIONS/RECOMMENDATIONS: Our analyses suggest that curricular intensification increased the inclusiveness and decreased the selectivity of the mathematics tracking regime in Towering Pines middle schools. However, the findings suggest that this constrained curriculum strategy may have may have unintended negative consequences for student achievement.

Using baby books to change new mothers' attitudes about corporal punishment.

OBJECTIVE: Research has found corporal punishment to have limited effectiveness in altering child behavior and the potential to produce psychological and cognitive damage. Pediatric professionals have advocated reducing, if not eliminating its use. Despite this, it remains a common parenting practice in the US. METHODS: Using a three-group randomized design, this study explored whether embedding educational information about typical child development and effective parenting in baby books could alter new mothers' attitudes about their use of corporal punishment. Low-income, ethnically diverse women (n=167) were recruited during their third trimester of pregnancy and followed until their child was 18 months old. RESULTS: Findings from home-based data collection throughout this period suggest that educational baby books compared with non-educational baby books or no books can reduce new mothers' support for the use of corporal punishment (respective effect sizes=.67 and .25) and that these effects are greater for African-American mothers (effect sizes=.75 and .57) and those with low levels of educational attainment (high school diploma, GED, or less) (effect sizes=.78 and .49). CONCLUSION: Given their low cost and ease of implementation, baby books offer a promising way to change new mothers' attitudes and potentially reduce the use of corporal punishment with infants and toddlers.

Using baby books to increase new mothers' safety practices.

OBJECTIVE: To determine whether educational baby books are an effective method for increasing low-income, first-time mothers' safety practices during their child's first 18 months. METHODS: Primiparous women (n = 167) were randomly assigned to 1 of 3 groups: an educational book group, a noneducational book group, or a no-book group. Home visits and interviews measured safety practices when women were in their third trimester of pregnancy (baseline) and when their children were 2, 4, 6, 9, 12, and 18 months of age. RESULTS: Women in the educational book group had fewer risks in their homes and exercised more safety practices than the no-book group (- 20% risk reduction; effect size = -.30). When the safety practices involved little time or expense (eg, putting away sharp objects), the educational book group was significantly more likely to engage in these behaviors than the no-book group (40% higher practices; effect size = 0.19) or noneducational book group (27% higher practices; effect size = 0.13). However, no differences were found between groups for behaviors that required high effort in time, money, or hassle (eg, installing latches on cabinets). CONCLUSIONS: Educational baby books appear to be an easy and low-cost way to increase the safety practices of new mothers, especially if the practices involve little to no time, money, or hassle.
