This dissertation draws on both qualitative and quantitative approaches to investigate the linguistic practices of teachers and children who are learning Mandarin Chinese as a Heritage Language (CHL) in two dual immersion preschools in California. CHL children have been interpreted as novice members in local speech communities who actively explore…

This study examined the influence of linguistic input on the development of productive and receptive skills across three fundamental language domains: lexico-semantics, syntax, and phonology. Seventy-one (35 female) Basque-Spanish bilingual children were assessed at three time points (Fall 2018, Summer 2019, Winter 2021), between 4 and 6 years of…

This study aims to identify the phonological error patterns of normally developing children who speak colloquial Jordanian Arabic dialect and to provide normative data for the age of suppression for each phonological error pattern. One hundred fifty-four normally developing children (68 females and 86 males) ranging from 3 to 6.5 years were…

The extent of quantitative and qualitative differences in phonological development between bilingual children and their monolingual counterparts remains unresolved, especially with regard to typologically-related languages. The current study used a comparative research design to examine the phonological skills of preschool children speaking Polish…

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.…

Purpose: This study aims to examine the associations of phonological, lexical, and grammatical skills within and between languages in Mandarin-English bilingual preschoolers. Method: Sixty-three Singaporean Mandarin-English bilingual children aged 3-5 years were assessed for articulation, receptive vocabulary, and receptive grammar using…

A key to reducing reading difficulty, particularly for children living in poverty, is to provide high quality, explicit, and well-planned instruction from the start of a child's school career. Preschools that provide quality language, literacy, and content instruction have produced promising positive effects on children's later academic…

This study explored what kinds of phonological strategies are used by children and how they scaffold each other while they solve tasks in a digital literacy game. The theoretical basis of this study lies in Vygotsky's thoughts on the role of social interaction in learning and in the concept of peer scaffolding. The data included eight videotaped…

Clinical Question: Would a bilingual preschooler with suspected speech sound disorder (P) be more accurately diagnosed via an assessment approach that integrates sociolinguistic information (I) or via standardized assessment with traditional scoring modifications (C) as shown by diagnostic compatibility with the converging concern approach (O)?…

Fast mapping weaknesses in children with specific language impairment (SLI) may be explained by differences in disambiguation, mapping an unknown word to an unnamed object. The impact of language ability and linguistic stimulus on disambiguation was investigated. Sixteen children with SLI (8 preschool, 8 school-age) and sixteen typically…

This longitudinal case study documents the emergence of bilingualism in a young monolingual Mandarin boy on the basis of an acoustic analysis of his vowel productions recorded via a picture-naming task over 20 months following his enrollment in an all-English (L2) preschool at the age of 3;7. The study examined (1) his initial L2 vowel space, (2)…

There has been increasing interest in both Canada and the United States in implementing all-day Kindergarten programs. Education policy makers stress the need for countries to take initiative in educating children so they are more successful once they begin their formal schooling process. But is a longer school day the only solution to the problem…

This study investigated cross-linguistic influence in acquisition of a second lexicon, evaluating Samoan-English sequentially bilingual children (initial mean age 4 ; 9) during their first 18 months of school. Receptive and Expressive Vocabulary tasks evaluated acquisition of four word types: cognates, matched nouns, phrasal nouns and holonyms.…

The DAPPLE (Dynamic Assessment of Preschoolers' Proficiency in Learning English) is currently being developed in response to a clinical need. Children exposed to English as an additional language may be referred to speech and language therapy because their proficiency in English is not the same as their monolingual peers. Some, but not all, of…

Many U.S. classrooms today have at least some children with limited abilities to understand and express themselves in English. Two critical factors spell success or failure for teachers who have dual language learners (DLLs) in their classrooms: the teacher's understanding of and respect for the initial difficulties in learning a second language…
