High-quality Tier 1 instruction is frequently conceptualized as the "foundation" for other tiers of intervention within multi-tiered systems of support (MTSS) models (Gersten et al., 2009). However, the vast majority of Tier 2 intervention studies do not account for Tier 1 variables when examining intervention effectiveness (Hill et al.,…

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…

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…

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…

Parent-teacher relationship (PTR) quality is linked to child and family-school functioning and may be especially important in the school adjustment of autistic children. However, measurement of PTR quality has been limited by inconsistency in the use of measures, a paucity of two-informant measurement, and limited psychometric consideration. We…

Scale-up of universal social-emotional learning (SEL) programs has become a priority in schools to promote positive social outcomes for all students. Although studies have examined student outcomes associated with school-based SEL when extensive training and support are provided, research on teacher SEL implementation practices under typical…

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…

Strategic and Interactive Writing Instruction (SIWI) involves teaching cognitive writing strategies and apprenticing novices within collaborative writing communities. It is responsive to deaf students' diverse language experiences through embedded metalinguistic/linguistic components. A randomized controlled trial of SIWI was conducted with 15…

Federal accountability policy mandates that states administer standardized tests beginning in third grade. In turn, third-grade test scores are often viewed as a key indicator in policy and practice. Yet literacy struggles begin well before third grade, as do racial and socioeconomic disparities in children's literacy skills. Kindergarten…

Experiencing large differences between pre-k and kindergarten classroom contexts may affect children's academic development as they start school. This study examined differences between classroom contexts in pre-k and kindergarten (teacher-child interactions, time on academic content, and academic rigor) and associations with literacy, language,…

Continuity of pre-k and kindergarten classroom experiences is a key area of interest for early childhood researchers interested in supporting public pre-k children's development over time. To advance the empirical evidence on this topic, this study examined whether differences in classroom experiences as children transition from pre-k to…

This paper reports the results of a randomized controlled trial evaluating "We Have Skills," a brief curriculum designed to teach early elementary students academic and social skills as well as improve teacher efficacy in classroom management. Intervention efficacy was tested with 127 teachers, randomly assigned to condition, and 2,817…

Peer isolation poses risks to children's social-emotional and academic development, contributing to internalizing and externalizing problems and school adjustment difficulties. To deepen scholarly understandings of peer isolation in early classroom settings, the current study examined the co-occurrence of child characteristics associated with…

This study investigated the presence of word reading difficulties in a sample of students in Grades 1-4 (n = 357) identified with language and reading comprehension difficulties. This study also examined whether distinct word reading and listening comprehension profiles emerged within this sample and the extent to which these groups varied in…
