The current study examined the contexts in which a preschool teacher professional development intervention was more versus less effective in improving student outcomes. We used a fixed intercept, random coefficient (FIRC) modeling approach to explore the contextual characteristics inside and outside school walls that predicted differential…

Purpose: Estimating the sequential associations between educators' and children's talk during language learning interactions requires careful consideration of factors that may impact measurement stability and resultant inferences. This research note will describe a preliminary study that used generalizability theory to understand the contribution…

Nursery practitioners often highlight the difference between the children who attend morning sessions and those who attend afternoon sessions, with the feeling that the morning session children are more receptive and show greater improvement in their development than those who attend in the afternoon, but no specific data OR evidence has been…

"Research Findings:" Promoting children's science knowledge by adequate measures such as guided or free play is a cardinal goal of preschool. However, there is considerable variability in preschool teachers' instructional quality in block play, which might be associated with children's domain-specific science skills but also their…

Supporting language skills for children who evidence delays in preschool is an important area of focus for school-age reading outcomes. Two preschool teachers were trained to implement a play-based language intervention, Enhanced Milieu Teaching (EMT), with children from low-income households with delayed language skills. A multiple-baseline…

The current study was designed to determine whether classroom quality (i.e., the quality of teacher--child interactions) served as a mediator of peer effects with respect to preschool children's gain in language skills over an academic year. Participants were 670 preschool-age children (64.6% boys; "M" = 4 years, 4 months, "SD"…

Purpose: This study describes the language diversity (the within-group variability in dual-language skills) of a sample of Latino dual-language learners (preschoolers, 3-5 years of age) and how language diversity is related to home and classroom factors. Method: A sample of 161 caregivers and their preschoolers participated in this study.…

A sample of 496 early childhood teachers was assigned randomly in two phases to a series of professional development (PD) interventions. Phase I intervention was a 14-week course on effective teacher-child interactions. Participants were then re-randomized into Phase II intervention, which consisted of individual, interactions-focused coaching.…

This article focuses on preschool teachers' views on in-class science activities with Syrian refugee children. Studies concerning science teaching with bilingual children have issues about language and communication. In this study, data were collected by using 9 semi-structured open-ended questions. The case study method was used as research…

Language serves as a mechanism through which children are able to interact and communicate with others. Thus, when children do not develop language at a typical pace, there may be cause for concern. The purpose of the current study was to examine the language production of children displaying various forms of social withdrawal (reticent,…

Background: This study tested a preschool-home partnership intervention, in which early childhood teachers encouraged the parents/caregivers of preschoolers to engage in dialogic reading at home. This was an experimental test of Bronfenbrenner's hypothesis that parental involvement in early care and education programs should promote child…

Research has found that children who attend Head Start for more than one year tend to score higher on cognitive skills at the end of pre-K or at kindergarten entry than children who attend for one year or less (Lee 2011; Wen et al. 2012b; Xue et al. 2016). Although attending Head Start for more years is linked with higher cognitive scores,…

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 one state. Relative to…

"Pre-K Mathematics" is a supplemental mathematics program focusing on a range of mathematical concepts to help develop children's informal mathematical knowledge. The "Pre-K Mathematics" program includes teacher-led, small-group mathematics activities that are engaging and hands-on, as well as caregiver-child activities that…

The purpose of this study was to examine the relationship between language skills and behavioural problems and the potential moderating role of the quality of classroom emotional support in this relationship among 242 preschool children from low-income families. The "Preschool Language Scale-5" was administered individually to each…
