Research Findings: Early childhood teachers' talk is a key ingredient in children's early language and literacy development, but there has been little systematic synthesis of observational studies that examine relationships between teacher talk and child oral language. In this systematic review of 54 studies, we investigate and synthesize the…

Research Findings: The present study investigates both the proximal processes and contextual influences on children's oral language development in preschool. We examine whether teacher language practices vary across activity settings and program type, which teacher language practices predict children's oral language skills, and potential…

Research Findings: Children's oral language skills lay the foundation for later literacy and can be fostered through responsive conversations with teachers. However, such conversations are rare in preschool, particularly between teachers and dual language learners (DLLs), or students who speak a minoritized language at home. DLLs benefit when…

Research Findings: This study conducted a systematic review and meta-analysis to examine the relationship between the home environment and the development of English as a second/foreign language for young Asian children. A systematic search of relevant databases generated 22 eligible studies published between 2001 and 2020 (N[subscript…

This secondary analysis study examined patterns, predictors, and outcomes of dual language learners' (DLLs') development in Spanish and English. Research Findings: Latent profile analysis identified three groups of DLLs: Balanced Bilinguals (54%), English-Dominant Bilinguals (25%), and Spanish-Dominant Bilinguals (21%). These groups had fairly…

Research Findings: We examined the amount of preschool lead/assistant teachers' English/Spanish language use and relations between quality of teacher-child interactions, and Dual Language Learners' (DLLs) English/Spanish bilingual vocabulary in 31 English-medium Head Start classrooms. Measures in this study included (a) children's conceptual…

Research findings: This study examined the dual language development and experience of the understudied Chinese dual language learners (DLLs). Twice in the preschool/pre-k year (about 4 months apart), we assessed 39 Chinese 3- and 4-year-old DLLs' receptive vocabularies in English and Chinese, interviewed 37 parents about the language use and…

Research Findings: Shared-picture book reading can stimulate children's mathematical development. Evidence of learning-supportive characteristics in picture books is limited in this domain. A first step is systematically analyzing the occurrence of domain-specific features in publicly available picture books. We analyzed the occurrence of general…

Research Findings: As the population of Hispanic children grows within U.S. preschools, it is increasingly important to understand how these classrooms facilitate school readiness, such as positive engagement with teachers, peers, and tasks, for Spanish-speaking Dual Language Learners (DLLs). A growing literature base indicates that DLL students'…

Research Findings: Using two groups of dual language learners (DLLs), the current study examined links between two developmental constructs closely linked to school readiness: the home language environment (HLE) and executive function (EF). In a sample of 90 children (age range = 38-70 months, 59% girls) from either Mexican American (MA, N = 46)…

Research Findings: In the context of parent-child book sharing, cultural influences on cognitive distancing language and associations with child executive function (EF) have been understudied. This study examined cultural group similarities/differences in parent and child book-sharing distancing language among preschool-aged dual language learners…

Research Findings: This study examined the relation between early childhood education (ECE) participation and early child development in Myanmar. It considered whether this relation varied by ethnic group, language(s) spoken at home, and language(s) of ECE instruction. Participants were 1,494 children (759 girls) from Myanmar, aged between 36 and…

Two consequentially related education policy topics in the United States are kindergarten entry assessments (KEAs) and the growing number of students who are "English learners" (ELs). In this study, I compared the content of, and home language use policies for six state KEAs, all of which were comprised of items from the GOLD®…

Research Findings: This study of kindergarten monolingual and Dual Language Learners (DLLs) (N=263; mean age = 63.40 months) and their teachers (N=27) found significant mean differences in the observed quality of language interactions in classrooms with differing proportions of DLLs. Teachers instructing in classrooms with higher numbers of DLLs…

Following a theoretical framework that recognizes the potential of promotive and inhibitive effects on children's development, this study explored child-, family-, classroom-, and school-level factors as predictors of Latinx (N = 4,590) students' early elementary science achievement. Research Findings: Employing a path modeling approach with…
