Most US students attend coeducational classes, but to what extent do students feel integrated into the entire classroom of their peers, especially with other-gender peers? The major goal of this research was to investigate how variations in gender integration (GI), measured by students' expectancies about inclusion, efficacy, and social costs of…

Autistic students often experience peer relationship difficulties. As peer acceptance and rejection may be malleable over time, we examined predictors of change in peer acceptance and peer rejection among early elementary-age autistic students. We followed 166 autistic children (mean age: 6.1 years [range: 4-8], 82.5% boys, grades preK-2nd)…

Early elementary students on the autism spectrum are at risk for poor quality student-teacher relationships (STRs), a key contributor to student outcomes. However, these students' own appraisals of their STRs are nearly absent from the literature. This study examined children's perspectives of STRs and agreement with teacher-reported STRs for a…

Teachers of students with emotional and behavioral disorders face unique challenges in the classroom that are often not addressed in teacher preparation, which may result in diminished outcomes for teachers and students. The Integrated Literacy Study Groups professional development was designed to support the needs of teachers of students with or…

Narration has been shown to be a foundational skill for literacy development in school-age children. Elementary teachers routinely conduct classroom lessons that focus on reading decoding and comprehension, but they rarely provide instruction in oral narration (Hall et al., 2021). This multisite randomized controlled trial was designed to…

Promoting prosocial behavior toward those who are dissimilar from oneself is an urgent contemporary issue. Because children spend much time in same-gender relationships, promoting other-gender prosociality could help them develop more inclusive relationships. Our goal in the present research was to better understand the extent to which…

Boys and girls sit together in most classrooms, but do they interact? Based on forty-year-old evidence, coeducational classes may not be coeducational but instead be segregated by gender, which may undermine student success. Our goal is to answer this question in today's classrooms. We used longitudinal data to assess gender segregation in 26…

We present an aggregation scheme that increases power in randomized controlled trials and quasi-experiments when the intervention possesses a robust and well-articulated theory of change. Intervention studies using longitudinal data often include multiple observations on individuals, some of which may be more likely to manifest a treatment effect…

The purpose of this study was to examine the efficacy of the Family Check-Up initiated during kindergarten on teacher-report of children's emotional and behavior concerns in fourth grade. Participants were 57 primary caregivers, along with their children and teachers. Participants were randomized to a Family Check-Up condition or school-as-usual…

Background: Student academic behavioral engagement (BE) contributes to learning and school success. Student-teacher relationships (STRs) may promote BE, although previous findings regarding how these constructs are associated over time are mixed. For young autistic students who face barriers to early school success, a high-quality STR may serve as…

COVID-19 significantly impacted the educational and home environments for students throughout the Commonwealth of Virginia in ways that may have impacted student learning, as measured by standardized exams. We analyze statewide, student-level administrative and assessment data on the Standards of Learning (SOL) reading and math tests for the…

Powell, Berry, et al. (in press) conducted a randomized control trial assessing the effects of two variants of word-problem intervention with third graders (n = 304) experiencing mathematics difficulty. Students were assigned to a business-as-usual condition (BaU) or one of two variants of word-problem intervention. One variant included a…

The "Framework" and NGSS bring to the forefront the role of language in doing science and in learning from doing science. Yet, most existing science assessments for elementary learners do not integrate or attend to aspects of scientific language and literacy that are essential components of science proficiency. Accordingly, there is a…

Motion remains a significant technical hurdle in fMRI studies of young children. Our aim was to develop a straightforward and effective method for obtaining and preprocessing resting state data from a high-motion pediatric cohort. This approach combines real-time monitoring of head motion with a preprocessing pipeline that uses volume censoring…

Measurement and statistical investigation are areas of mathematics visibly neglected in educational intervention research, particularly studies involving students with or at risk for mathematics difficulties (MD). This shortage is concerning given the importance these areas hold in students' pursuit of mathematical proficiency. This study…
