Within the context of the Direct and Indirect Effects Model of Writing (Kim & Park, 2019), we examined a dynamic relations hypothesis, which contends that the relations of component skills, including reading comprehension, to written composition vary as a function of dimensions of written composition. Specifically, we investigated (a) whether…

Children's ability to discriminate nonsymbolic number (e.g. the number of items in a set) is a commonly studied predictor of later math skills. Number discrimination improves throughout development, but what drives this improvement is unclear. Competing theories suggest it may be due to a sharpening numerical representation or an improved ability…

This study investigated the technical characteristics of four early measurement curriculum-based measures (EM-CBMs) designed to assess concepts related to linear measurement and iteration. The sample consisted of 221 first grade students. Data were collected at two time points approximately 10 weeks apart. Reliability and concurrent and predictive…

This study examined: (1) school-based avoidance among students with problematic anxiety, (2) teachers' levels of accommodation of avoidant behaviour, and (3) the relation between teacher accommodation and student avoidance and anxiety. Participants included 31 elementary school students with problematic anxiety (mean age = 7.7 years; range 5-11;…

Schools are the primary setting in which autistic youth receive intervention, yet fidelity to implementation of evidence-based practices (EBPs) for autism in schools varies. Fidelity is an important metric to determine whether educators are delivering EBPs as designed, and there are many different factors that predict fidelity to EBP…

This preregistered study examined whether extraneous illustration details promote attentional competition and hinder reading comprehension in beginning readers. Reading comprehension was highest in the Streamlined Condition (text + relevant illustrations) compared to a Standard Condition (text + relevant illustrations + extraneous illustrations)…

The present study reports findings from a school-level randomized controlled trial (RCT) of the Double Check cultural responsivity and student engagement model. Consistent with the focus of this special issue on the conceptual and methodological advances for understanding contextual, identity, and cultural effects in intervention research, we…

Because standardized tests in science are not given to PreK-3 students in Ohio, this report examined the longitudinal effects of learning from a teacher who had participated in the NURTURES professional development program. Specifically, it looked at the effects on students' mathematics and reading learning in grades 2-5 and science learning in…

The purpose of this systematic observation study was to improve our understanding of small-group reading instruction for kindergarten students at risk for reading difficulties (RDs). We aimed to observe and document activity types addressed as well as instructional practices and materials employed during small-group instruction, with a particular…

Although school-based preventive parenting interventions have been found to promote children's social-emotional skill development and behavioral functioning, it is important to understand potential barriers to engagement in such programs to ensure that intervention access is equitable and likely to reach those who could most benefit. In the…

We investigated the technical characteristics of a brief early numeracy screening battery for both English learners (ELs) and English proficient students (EPs). Results indicated there were differences in performance of ELs and EPs. Further, we found reasonable overall accuracy of the screener predicting student outcomes. Similar overall accuracy…

The purpose of this study was to explore the effectiveness of a universal classroom-based socialemotional learning (SEL) program for first grade students. Forty classrooms from 13 elementary schools across 3 states participated in the trial. Teachers in classrooms randomly assigned to the implementation condition were provided with free access to…

In this study, we examined burst length and its relation with working memory, attentional control, transcription skills, discourse oral language, and writing quality, using data from English-speaking children in Grade 2 (N = 177; M[subscript age] = 7.19). Results from structural equation modeling showed that burst length was related to writing…

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)…
