Usage-based theories of language development underscore the importance of children using language to learn language. Few investigations have applied usage-based theories to dual language learners (DLLs), who comprise a growing share of children attending early education programs in the U.S. Three studies were carried out to investigate the role of…

The purpose of this exploratory study was to examine the longitudinal, bidirectional relations between receptive and expressive Spanish and English language and internalizing and externalizing behavior problems in a sample of 97 preschool children from Spanish-speaking, homes who were enrolled in a U.S. Head Start program. Eight cross-lagged path…

This article examines the language ideologies of the lead teacher and of five Mexican mothers of Spanish-speaking, emergent bilingual children in a Head Start program in Arizona. Data from semi-structured interviews, informal conversations, and participant-observation field notes were analyzed using the interrelated concepts of language ideologies…

Purpose: The purpose of this study was twofold: (a) to describe how the language diversity (i.e., the within-group variability in dual-language skills) of Latino dual-language learner (DLL) preschoolers was related to their science readiness skills and (b) to describe the importance of language of science instruction for Spanish-dominant children.…

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…

This study explores the collaborative process that two Korean-English and one Spanish-English bilingual Early Head Start family childcare educators, two instructional coaches, and the author engaged in as they co-created intentional bilingual approaches to supporting young emergent bilinguals. A thematic analysis of the design-based approach of…

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…

The present study examined the roles that language of assessment, language dominance, and teacher language use during instruction play in Dual Language Learner (DLL) science scores. A total of 255 Head Start DLL children were assessed on equated science assessments in English and Spanish. First overall differences between the two languages were…

The purpose of this study was to explore the use of code-switching in the narratives of dual-language Latino preschoolers, specifically by examining its incidence, types, functions, and grammaticality. Previous work has investigated code-switching in younger children and in older children and adults, but relatively little work has investigated…

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…

The global spread of English has made it the dominant language in academic publishing (Hyland, Ken. 2015. "Academic Publishing: Issues and Challenges in the Construction of Knowledge." Oxford: Oxford University Press). Influenced by enterprise culture, scholars from peripheral non-Western countries face mounting pressure to publish in…

Using a nationally representative sample of dual language learners (DLLs) attending Head Start, this study investigated how the language used for instruction and the proportion of DLLs in the class was associated with English and Spanish receptive vocabulary development between the fall and spring (n = 531). Based on teacher report of the language…

In recent decades, the share of ethnically and linguistically diverse children enrolled in schools in the United States has exponentially increased. Despite the growing representation of ethnic minority and dual language learner (DLL) children, there is persistent evidence of early vocabulary gaps between low-income and DLL children and their…

Since the 1960s, the U.S. Department of Education has enthusiastically embraced bilingual education. In this paper, the author evaluates the federal bilingual education program. Based on her studies of the implementation of bilingual education in California, Massachusetts, and New York City, she concludes that the program is of dubious value. She…
