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…

Background: Gaps between dual language learners (DLLs) and monolingual English-speaking children have been reported at kindergarten entry, and many DLL children are classified as long-term English learners, having less access to the general curriculum in the upper grades (NASEM, 2017). The supposed underperformance of DLLs might be due to the…

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.

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…

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…

This study analyzed challenges faced by teachers in rural and Indigenous schools, and the impact of pedagogical mentorship in contributing towards more culturally and linguistically relevant education. Using a case from Guatemala, this article explored pedagogical mentorship as an in-service teacher training resource for multi-lingual and…
