Most children experience some form of grouping in the classroom every day. Understanding how teachers make grouping decisions and their impacts on children's social development can shed light on effective teacher practices for promoting positive social dynamics in the classroom. This study examined the influence of teachers' grouping strategies on…

Research Findings: The purpose of this study was to test a theoretical measurement model representing four proposed dimensions of the classroom ecology in pre-K to third-grade classrooms. The four proposed dimensions of Classroom Composition, Peer Network and Norms, Teacher Practices, and Student Experiences were evaluated using data collected in…

This study applied multilevel modeling to examine the relationship between the percentage of children with mild/moderate disabilities in classrooms and children's language and literacy achievement over an academic year. The sample included 516 preschool children (mean age = 52.3 months, SD = 6.3) in 75 classrooms; 42% of the children had…

Peer-effects research finds that preschool children's language growth is associated with classmates' skills and that children with disabilities especially benefit from classmates with higher skills. The current study estimates the amount of "peer language resources" individual children access through their classroom-based peer social…

This study examined implementation of an evidence-based home reading program by caregivers of children with language impairment. Caregivers received materials and supports to read with their children for 15 weeks, four times weekly; in total, 128 caregivers were enrolled. Survival analysis showed that 55% of caregivers completed the program, and…

Research Findings: The present study examined the extent to which instructional practices, including curriculum, in pre-K through third grade are vertically aligned. Attention was directed to teachers' grouping practices, academic content, and pedagogical methods given their importance for students' learning. Variable- and person-centered analyses…

Professional development (PD) is a potentially important mechanism for enhancing classroom practices and children's learning. In this large-scale randomized controlled trial, we examined the effectiveness of language and literacy PD, with and without coaching, offered at scale to early childhood educators (n = 546) across 1 state. Relative to the…

In this study, we identified child- and family-level characteristics most strongly associated with clinical identification of language disorder for preschool-aged children. We used machine learning to identify variables that best classified children receiving therapy for language disorder among a sample of 483 3- to 5-year-old children (54%…

Background: Children with developmental language disorders (DLDs) often struggle with classroom behaviour. No study has examined whether positive teacher-child relationships may act as a protective factor for children with DLDs in that these serve to enhance children's important classroom-learning behaviours. Aims: To examine the association…

This study provides a broad, macro-analysis of how the home literacy environment (HLE) manifests among Mayan families with preschool-aged children in Yucatan, Mexico. Despite a substantial body of work showing the significant contribution of the HLE to children's reading achievement in the U.S., little work examines the HLE and children's learning…

This study aimed to examine the psychometric properties of an instrument designed to measure parental practices to support young children's learning and literacy at home (ELLS) and explore the predictive validity of the instrument by examining the associations between the ELLS subscales (basic concepts, phonological awareness, conceptual…

Structural quality in childcare centers is considered a precondition for process quality, which in turn is related to children's outcomes. However, the evidence on relations between structural and process quality is mixed. Moreover, despite strong theoretical claims, empirical evidence supporting the indirect relation of structural features…

Globally, there is great interest in enhancing young children's literacy development as a route to improving worldwide literacy. To contribute to this area of interest, this paper reports findings from a multi-pronged early-literacy program designed to improve the print-knowledge of young children in Yucatec Mayan villages. The school-based…
