K-12 Education

A research synthesis points to the added-value—benefits to social and emotional development, as well as learning outcomes—for students of color taught by teachers of color. Given ongoing education debates, policymakers can use this evidence base to craft legislation aimed at increasing the ethnoracial diversity of the U.S. educator workforce. To begin, historical research shows how Latinx and Black teachers have supported their Latinx and Black students’ social and emotional development during state-sanctioned school segregation. Contemporary qualitative and quantitative research highlights how teachers of color improve social and emotional development, as well as learning, for their students of color. Implications for the reauthorization of the Higher Education Act are discussed.

In the forty plus years since passage of the Individuals with Disabilities Education Act (IDEA), special education has grown in the number of students and amount spent on services. Despite this growth, the academic performance of students with disabilities (SWDs) remains troubling low compared to general education students (GENs). To some extent, these differences reflect persistent underlying disabilities, but they may also reflect ineffective special education services. Does special education improve academic outcomes for students with disabilities? There is surprisingly little evidence to guide policy and answer this question. This paper provides an answer for the largest disability group, students with learning disabilities (LDs), using rich data from New York City public schools. Because the majority of LDs are classified after school entry, we observe outcomes both before and after classification, allowing us to gauge impact using within-student pre/post comparisons and, ultimately, student fixed effects in regression models exploring impacts. We find that academic outcomes improve for LDs following classification into special education, and impacts are largest for those entering special education in earlier grades. Results are robust to alternative specifications and falsification tests bolster confidence in a causal interpretation. Differences in impacts by gender and race/ethnicity, grade of classification, and settings shed light on possible mechanisms.

Research has begun to investigate whether teachers and schools are as effective with certain student subgroups as they are with the overall student population.  Most of this research has examined the issue by trying to produce causal estimates of school contributions to short-term student growth (usually using value-added models) and has emphasized rank orderings of schools by subgroup.  However, not much is known about whether schools contributing to long-term growth for all students are also contributing to student growth by subgroup in ways that might close achievement gaps.  In this study, schools’ contributions to student growth are estimated separately for Black versus White students.  Results show that focusing on rank orderings of schools alone can mask troubling trends in relative achievement over time.  Options for how policymakers can sensibly hold schools accountable for student growth, including under The Every Student Succeeds Act, are discussed.

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 enrollment and graduation rates for minority and non-immigrant students from moderately and severely disadvantaged backgrounds. The findings are obtained from a privately sponsored, lottery-based voucher intervention in New York City that began in 1997. College enrollment and degree attainment as of the fall of 2017 were obtained from the National Student Clearinghouse. We find no significant effects of offers on minority students from severely disadvantaged backgrounds but significant effects of six to eight percentage points on those from moderately disadvantaged households. Similar results are obtained for students born of non-immigrant mothers. Some policy implications are discussed.

The well-documented racial disparities in school discipline have led many school districts in the U.S. to adopt restorative justice practices. The restorative justice philosophy differs from traditional disciplinary action by placing an emphasis on restitution and improving behavior rather than punishment. While models of restorative justice are descriptively and theoretically promising, research on restorative practices in schools is limited. We use student-level administrative data and a difference-in-difference design to measure the changes in student discipline outcomes that occurred under restorative justice in Pacific City schools between the 2008-2017 school years. Results indicate that restorative justice practices led to an overall reduction in disciplinary action. However, results also show that restorative justice practices had differential effects between racial groups, with White students benefiting most from restorative justice. These findings suggest that while the overall effects of restorative justice are promising, these practices may unintentionally widen the racial disproportionality in school discipline they are instituted to mitigate.

Despite growing concern over teachers’ ability to live comfortably where they work, we know little about the systematic impacts of affordability on teachers’ well-being, particularly in high-cost urban areas. We use novel survey data from San Francisco Unified School District to identify the patterns and prevalence of economic anxiety among teachers and assess how this anxiety relates to teachers’ attitudes, behaviors, and turnover. We find that San Francisco teachers have far higher levels of economic anxiety on average than a national sample of employed adults, and that younger teachers are particularly financially anxious. Furthermore, such anxiety relates to job performance and teacher retention— economically anxious teachers tend to have more negative attitudes about their jobs, have worse attendance, and are 50 percent more likely to depart the district within two years after the survey.

Although program evaluations using rigorous quasi-experimental or experimental designs can inform decisions about whether to continue or terminate a given program, they often have limited ability to reveal the mechanisms by which complex interventions achieve their effects. To illuminate these mechanisms, this paper analyzes novel text data from thousands of school improvement planning and implementation reports from Washington State, deploying computer-assisted techniques to extract measures of school improvement processes. Our analysis identified 15 coherent reform strategies that varied greatly across schools and over time. The prevalence of identified reform strategies was largely consistent with school leaders’ own perceptions of reform priorities via interviews. Several reform strategies measures were significantly associated with reductions in student chronic absenteeism and improvements in student achievement. We lastly discuss the opportunities and pitfalls of using novel text data to study reform processes.

Growing evidence suggests that preservice candidates receive better coaching and are more instructionally effective when they are mentored by more instructionally effective cooperating teachers (CTs). Yet, teacher education program leaders indicate it can be difficult to recruit instructionally effective teachers to serve as CTs, in part because teachers worry that serving may negatively impact district evaluation scores. Using a unique dataset on over 4,500 CTs, we compare evaluation scores during years these teachers served as CTs to years they did not. In years they served as CTs, teachers had significantly better observation ratings and somewhat better achievement gains, though not always at significant levels. These results suggest that concerns over lowered evaluations should not prevent teachers from serving as CTs.

Schools utilize an array of strategies to match curricula and instruction to students’ heterogeneous skills. While generations of scholars have debated “tracking” and its consequences, the literature fails to account for diversity of school-level sorting practices. In this paper we draw upon the work of Sørenson (1970) to articulate and develop empirical measures of five distinct dimensions of school cross-classroom tracking systems: (1) the degree of course differentiation, (2) the extent to which sorting practices generate skills-homogeneous classrooms, (3) the rate at which students enroll in advanced courses, (4) the extent to which students move between tracks over time, and (5) the relation between track assignments across subject areas. Analyses of longitudinal administrative data following 24,000 8th graders enrolled in 23 middle schools through the 10th grade indicate that these dimensions of tracking are empirically separable and have divergent effects on student achievement and the production of inequality.

Many districts and states have begun implementing incentives to attract high-performing teachers to low-performing schools.  Previous research has found that these incentives are effective.  However, effects on the schools and students these teachers leave behind has not been examined.  This study focuses on the general equilibrium effects of recruiting effective teachers to Tennessee’s Innovation Zone (iZone) schools, one of the most successful turnaround initiatives in the nation (Zimmer, Henry, & Kho, 2017).  While there is some variation in the effects of losing these teachers, we find they range between -0.04 and -0.12 standard deviations in student test score gains.  However, an estimate including both these negative effects and the positive effects in iZone schools yields overall net positive effects.
