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…

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…

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…

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)…

Research on science achievement disparities by gender and race/ethnicity often neglects the beginning of the pipeline in the early grades. We address this limitation using nationally representative data following students from Grades 3 to 8. We find that the Black-White science test score gap (-1.07 SD in Grade 3) remains stable over these years,…
