Black teachers are critical resources for children and schools. In experimental data, I document large effects of Black upper-elementary teachers on the self-efficacy (0.9 SD) and classroom engagement (0.7 SD) of their Black but not non-Black students, potentially driven by role modeling. Black teachers also benefit the test scores (0.2 SD) and…

The fourth-grade 2019 National Assessment of Educational Progress (NAEP) Reading assessment shows that 34% of the nation's students perform below the "NAEP Basic" level. However, because there is no achievement-level description for below Basic, educators and policymakers lack information on the nature of the reading difficulties that…

Previous research provides evidence that developing a growth mindset--believing that one's capabilities can improve--promotes academic achievement. Although this phenomenon has undergone prior study in a representative sample of ninth graders in the United States, it has not been studied in representative samples of other grade levels or with…

Understanding how children's broader context influences their development is critical if we are to develop policies that help them flourish. Combining sociological, economic, and psychological literature, we argue that ability stratification--the degree to which children of similar levels of ability are schooled together--influences a child's…

This study represents an extension of the findings of Kieffer and Thompson (2018) and evaluates potential correlates of state- and district-level achievement gaps in reading and mathematics between monolingual and multilingual students. Using data from the National Assessment of Educational Progress, this study reported that there were substantial…

Although the promise of universal social-emotional learning (SEL) programs enhancing student academic outcomes has captured public attention, there has been limited research regarding such programs' impact on students' state test scores. We used multilevel modeling of follow-up data from a multiyear, multisite cluster-randomized efficacy trial to…

How do teachers account for homework-related inequalities? Our longitudinal ethnographic study reveals that, despite awareness of structural inequalities in their students' lives, elementary- and middle-school teachers' practices centered the myth of meritocracy. They treat struggles with math homework as products of students' and (particularly in…

National and state assessments show that English language learners (ELs) in elementary and secondary grades score lower in mathematics compared with their matched English proficient peers (EPs). To provide information on strategies for enhancing learning opportunities for ELs in language inclusive classrooms, we analyze the efficacy of…

The Common Core State Standards for Mathematics (CCSS-M) aim to engage students in complex mathematical practices, including modeling, reasoning, and argumentation. Currently, little is known about how teachers' daily instruction supports these practices. This study draws upon data from daily logs completed by third-, fourth-, and fifth-grade…

Policy and practice communities increasingly are emphasizing conceptual, cognitively demanding, and "ambitious" instruction. Within this context, we examine whether such practices serve the needs of students with specialized academic needs. Across upper-elementary classrooms in four districts, we find that exposure to…

As the COVID-19 pandemic upended the 2019-2020 school year, education systems scrambled to meet the needs of students and families with little available data on how school closures may impact learning. In this study, we produced a series of projections of COVID-19-related learning loss based on (a) estimates from absenteeism literature and (b)…

Prior research suggests that males outperform females, on average, on multiple-choice items compared to their relative performance on constructed-response items. This paper characterizes the extent to which gender achievement gaps on state accountability tests across the United States are associated with those tests' item formats. Using roughly 8…

Critics of test-based accountability warn that test preparation has a negative influence on teachers' instruction due to a focus on procedural skills. Others advocate that the adoption of more rigorous assessments may be a way to incentivize more ambitious test preparation instruction. Drawing on classroom observations and teacher surveys, we do…

Federal legislation and policy increasingly seek to address minority overrepresentation in special education due to concerns that U.S. schools are misidentifying children as disabled based on their race or ethnicity. Yet whether and to what extent this is occurring is currently in dispute. We estimated racial disparities in disability…

Several states have recently adopted or are pursuing policies that deny or revoke tenure from teachers who receive poor evaluation ratings over time based in part on quantitative measures of performance. Using data from the state of Florida, we estimate such value-added measures to consider the future effectiveness and number of teachers who would…
