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,…

Purpose: This study examined the effect of phonological overlap on English and Spanish expressive vocabulary accuracy as measured by the bilingual Expressive One-Word Picture Vocabulary Test--Fourth Edition (EOWPVT-IV). We hypothesized that if languages interact during an expressive vocabulary task, then higher phonological overlap will predict…

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…

This study documented the standardized tests and informal assessment techniques that school-based speech-language pathologists (SLPs) reported as most helpful for identifying vocabulary deficits and for monitoring progress. Speech-language pathologists (N = 142) working in U.S. public school settings completed an online survey that included…

Research has investigated how lexical-semantic and participant factors impact word learning in young children and adults. However, limited information pertaining to expressive vocabulary development exists for school-aged bilinguals--particularly those with developmental language disorder (DLD). Cross-linguistic differences in the semantic…

Purpose: Cognates, words in two languages that share form and meaning, can be used to support vocabulary development in bilingual children. Typically developing bilinguals have shown better performance on cognates versus noncognates. Of key interest is whether bilinguals with developmental language disorder (DLD) also show a cognate effect and, if…

Vocabulary knowledge is essential for successful language learning. However, little is known about young learners' vocabulary learning in a Thai EFL context and the teaching methods that facilitate vocabulary learning. The current study examined whether songs and total physical response (TPR) can facilitate preschoolers' vocabulary acquisition in…

This study investigated responsive and directive speech from 60 Finnish mothers to their 2-year-old children, as well as correlations with concurrent and later vocabulary. Possible gender differences with regard to both maternal speech and children's vocabulary skills were considered. There were no gender differences in maternal utterance…

The purpose of this study was to investigate the effects of dialogic reading on the expressive vocabulary skills of children with moderate to severe expressive impairments. Previous research has shown positive effects of dialogic reading on the language skills of children who are typically developing and on children who are at-risk for language…

Purpose: The purpose of the current study was to examine the role that the first language (L1), Spanish, at Pre-Kindergarten plays in predicting second language (L2), English, word reading in first grade. In addition, it examines the role of conceptual vocabulary in predicting word reading in English. Method: As part of a longitudinal study of…

The purpose of this study is to examine the bidirectional relationship between children's language development and challenging behaviors as well as the moderating roles of gender and race/ethnicity. We conducted a number of structural equation modeling analyses with a national representative sample (N = 2,462) of Head Start children from the 2014…

We examined how educating paraprofessionals in preschool classrooms on dialogic reading (DR) affected their storybook reading and effects on children's single word vocabulary. Through a single-case multiple-probe across participants design including four paraprofessionals and eight preschool children, we identified a functional relation between…

Background: Deafness has an adverse impact on children's ability to acquire spoken languages. Signed languages offer a more accessible input for deaf children, but because the vast majority are born to hearing parents who do not sign, their early exposure to sign language is limited. Deaf children as a whole are therefore at high risk of language…

This study investigated the relationship among home language use, parents' beliefs about dual language development, and Spanish-speaking children's vocabulary knowledge. Parents (n = 162) completed a questionnaire about their home language use and beliefs about dual language development, and elementary-age children (N = 190) -- Kindergarten…

Purpose: This study examined the effects of single-language and conceptual scoring on the vocabulary performance of bilingual children with and without specific language impairment. We assessed classification accuracy across 3 scoring methods. Method: Participants included Spanish-English bilingual children (N = 247) aged 5;1 (years;months) to…
