We investigated the role of bilingual parents' language proficiency in their reports of their children's vocabulary size. Sixty-four Spanish-English bilingual mothers whose L1 was Spanish reported their bilingual children's English and Spanish vocabularies and 37 monolingual L1 English-speaking mothers reported their monolingual children's English…

Many children learn language, in part, from the speech of non-native speakers who vary in their language proficiency. To investigate the influence of speaker proficiency on the quality of child-directed speech, 29 mothers who were native English speakers and 31 mothers who were native speakers of Spanish and who reported speaking English to their…

Purpose: Despite the unprecedented growth of Spanish-English dual language learners (DLLs) in new destination states--where DLLs have not been historically served--empirical understanding of their language and literacy skills is scant. Drawing on scientific understandings of bilingual language acquisition, we compare monolingually scored and…

This study investigated the stability of latent classes of students with learning disabilities among a heterogeneous sample of elementary-aged children whose first language is Spanish. To this end, children (N = 284) in Grades 1, 2, and 3 at Wave 1 (Year 1) were administered a battery of vocabulary, reading, math, and cognitive measures…

We present results of a randomized control trial of a two-generation English as a Second Language (ESL) program in which all families participated in Head Start while treatment parents also enrolled in a high dosage, family-focused ESL curriculum with supportive services. Examining 197 parent-child dyads among Spanish- (89%) and Zomi-speaking…

Purpose: The current study examined language control and code-switching in bilingual children with developmental language disorder (DLD) compared to bilingual peers with typical language development (TLD). In addition, proficiency in each language and cognitive control skills were examined as predictors of children's tendency to engage in…

Background: The educational context in South Africa does not always support the development of bilingualism to enable the cognitive and social advantages of dual language proficiency. The emphasis on English as the language of instruction overlooks bilingual competence. This study attempts to show that by considering conceptual vocabulary,…

Dual language learners make up an increasing share of preschool students, but they often perform worse than monolingual students on assessments measuring school achievement. This study compares Head Start classrooms implementing either the dual language model or the English with home language support model. The author examines how the models…

The United States is becoming a more culturally and linguistically diverse nation. This is especially true when we look at the youngest generation of learners. This growing diversity increases the need to accurately identify young children as dual language learners (DLLs) prior to kindergarten. Ensuring educators have a strong understanding of…

Bilingual children often show advanced executive functioning (EF) and false belief (FB) understanding compared to monolinguals. The latter has been attributed to their enhanced inhibitory control EF, although this has only been examined in a single study which did not confirm this hypothesis. The current study examined the relation of EF and…

Research Findings: The purpose of this study was to examine the potential contribution of teacher-child interactions to residualized Inhibitory Control (IC) gains over approximately a six-month period for preschoolers from predominantly low-income households. The study also explored whether the association between quality of teacher-child…

Relations between bilingual children's patterns of conversational code-switching (responding to one language with another), the balance of their dual language input, and their expressive and receptive proficiency in two languages were examined in 115 2½-year-old simultaneous Spanish-English bilinguals in the U.S. Children were more likely to…

This cohort-sequential study explored the components of working memory (WM) that underlie second language (L2) reading growth in 450 children at risk and not at risk for reading disabilities (RD) whose first language is Spanish. English language learners designated as balanced and nonbalanced bilinguals with and without risk for RD in Grades 1, 2,…

This study investigated the prevalence and stability of latent classes at risk for reading disabilities (RD) in elementary-aged children whose first language is Spanish. To this end, children (N = 489) in Grades 1, 2, and 3 at Wave 1 were administered a battery of reading, vocabulary, and cognitive measures (short-term memory [STM], working memory…

In recent decades, the composition of classrooms in the U.S. has reflected larger numbers of children who use English as their second language (ESL), including children of professional families from Indian backgrounds. The purpose of this qualitative study was to identify the perspectives of Indian parents regarding their children?s early…
