This study investigated if student placement in a primary grade 1-3 classroom with a teacher who had been trained in a U.S. science Framework-aligned [National Research Council. (2012). "A framework for K-12 science education: Practices, crosscutting concepts and core ideas." The National Academies Press] professional development science…

This study examines developmental change across adolescence in the similarity of friends versus nonfriends. This differential in similarity is a key aspect of the organization of the peer context of development: The stronger the correlation between friends for an attribute, the more the attribute delineates clustering and divisions of friendships.…

There is fear that adolescents have limited control over their digital technology use. The current research examines longitudinal (Study 1) and daily (Study 2) associations between U.S. adolescents' self-control and digital technological impairment and use. Using a large sample (N = 2,104; Wave 1: M[subscript age] = 12.36, 52% female, 57%…

Teachers' teaching self-efficacy and teachers' feelings of negative affect may be associated with students' academic achievement; however, little is known about how these factors directly affect adolescent students' math and reading achievement. The eighth-grade wave of the Early Childhood Longitudinal Study data was used to investigate teacher…

Scaling up educational interventions in the STEM (Science, Technology, Engineering, and Mathematics) field is critical but under-researched. We review and draw implications from a series of studies investigating the long-range impact of an implementation of an early mathematics scale-up model based on learning trajectories. Lasting effectiveness…

Under the integrated model of General Strain Theory (GST), the present study sought to examine whether delinquent peer association, social control, and negative emotion moderated the relations of distinctive cyberbullying roles with delinquency, as well as whether the moderating effects varied by gender among a nationally representative sample of…

Person × Environment mismatch theory has been applied to understanding how the classroom social ecology moderates associations between peer victimization and socioemotional well-being. In 2004, Bellmore et al. applied this theory to the ethnic composition and social climate of the classroom. The current study tested whether their findings…

Approximately one in 10 children in the United States is diagnosed with attention-deficit/hyperactivity disorder (ADHD), a disability that can negatively affect academic achievement, yet relatively few children with ADHD are in special education. To better understand factors that determine which students with ADHD are in special education, we…

Adolescence is a developmental period when youth are increasingly likely to turn to their peers for support, and it is also a time of increased salience and development of ethnic-racial identity (ERI). Ethnic-racial centrality, a dimension of ERI, could be a predictor in the development of peer support, as youth with a stronger self-concept on the…

Peer victimization is a widespread and heterogeneous phenomenon, especially during the transition to middle school, and is associated with numerous negative consequences. However, previous research is limited by variable-centric analyses and data manipulations that either fail to capture or mask the complexity of peer victimization many students…

Principals (policy makers) have debated the progress in U.S. student performance for a half century or more. Informing these conversations, survey agents have administered seven million psychometrically linked tests in math and reading in 160 waves to national probability samples of selected cohorts born between 1954 and 2007. This study is the…

This brief is a continuation of NWEA's ongoing research agenda focused on understanding how the COVID-19 pandemic has affected student reading and math outcomes. This report builds on previous findings to examine students' academic progress at the start of the third school year impacted by the pandemic. The goal of this brief is to summarize…

The 35th edition of the Annie E. Casey Foundation's "KIDS COUNT"® Data Book examines the unprecedented declines in student math and reading proficiency brought on by the COVID-19 pandemic's effect on education. The latest data from the National Assessment of Educational Progress reveals that between 2019 and 2022, fourth-grade reading…

Although Black and Latinx students disproportionately face exclusionary school discipline, prior research finds that the likelihood of suspension for Black students decreases when they are taught by greater proportions of Black teachers. Little prior work, however, has examined whether these effects generalize to large, diverse, urban school…

There is ongoing debate in the United States about just how diverse, inclusive, and equitable the opt-out movement--and grassroots education activism more broadly--has been over the past decade. Today, a prevailing stereotype holds that the opt-out movement predominantly mobilizes white, middle-class, and suburban parents and is therefore a force…
