While language dominance has been crucial in the study of bilingualism, recent research has called for more detailed measures to systematically account for the observation that bilinguals use different languages in different domains, a phenomenon formalized in the Complementary Principle. Few studies have systematically measured these…

Real-time attention coordination in parent-toddler dyads is often studied in tightly controlled laboratory settings. These studies have demonstrated the importance of joint attention in scaffolding the development of attention and the types of dyadic behaviors that support early language learning. Little is known about how often these behaviors…

In this study, the relationship between the family language practice and the level of linguistic (in)security of adolescent Gagauz speakers is examined in the context of an endangered language. To this end, a language-use questionnaire and linguistic insecurity scale were administered to 674 participants. The questionnaire included questions…

This study examined how Papiamento and Dutch attitude and home literacy environment of 168 children in fourth grade of the post-colonial Dutch Caribbean, predicted L1 and L2 reading literacy in sixth grade. Overall, children had higher scores for reading literacy in L1 Papiamento as compared with L2 Dutch. They showed more positive attitudes…

School leadership ranks as an essential factor for successful schools. The purpose of this study is therefore to investigate the effects of two central leadership practices -- "setting directions" and "managing instructional processes" -- on both instructional quality (mediator) and student achievement (target) in Austrian…

For bilingual children, home literacy experiences contribute to the development of both languages. In this study, survey data were gathered on the frequency of home literacy activities in two languages for forty-two early-elementary students in a French-English dual language immersion program. Using growth modeling, this study focuses on the…

This study examined the unique contribution of Home Literacy Environment (HLE), Classroom Literacy Environment (CLE), and parent and teacher expectations to the development of Dutch (L1) and English (L2) vocabulary in children in Dutch-English bilingual primary education. The children (n = 106) were tested on vocabulary in both languages in…

Research Findings: Using two groups of dual language learners (DLLs), the current study examined links between two developmental constructs closely linked to school readiness: the home language environment (HLE) and executive function (EF). In a sample of 90 children (age range = 38-70 months, 59% girls) from either Mexican American (MA, N = 46)…

Primary school children develop literacy practices in various domains and situations in everyday life. This study focused on the analysis of literacy practices of children aged 8-12 years from the perspective of their families. 1,843 families participated in the non-experimental explanatory study. The children in these families speak Spanish as a…

Understanding the long-standing educational inequities associated with socioeconomic status remains significant for transforming educational policies and practices. To better understand entanglements among socioeconomic status and students' performance in mathematics, we examined different home factors (including language of the test) that…

In the past few decades, literature has consistently suggested that bilingual children are at risk for academic failure due to their limited language skills. However, many of these studies included underprivileged bilingual children, and few of them attempted to disentangle the effects of bilingualism from the effects of socio-economic status.…

The present study explored the relationship between amount of dual language exposure, parents' language quality and bilingual competence among Chinese American children with autism spectrum disorder by using a cross-sectional correlational design. Thirty parent-child dyads participated in this study. Survey and observational data were collected…

This dissertation investigated how a bilingual's experiences can affect how their first language pronunciation can differ from monolingual speakers of their two languages. We used a methodology incorporating quantitative phonetic measurements of voice onset time and vowel formants, grammar and vocabulary tests, and qualitative measures of language…

Research Findings: This study conducted a systematic review and meta-analysis to examine the relationship between the home environment and the development of English as a second/foreign language for young Asian children. A systematic search of relevant databases generated 22 eligible studies published between 2001 and 2020 (N[subscript…

Research Findings: Are family literacy activities linked to gains in preschool-aged dual language learners' (DLLs') societal language vocabulary? To understand connections between literacy activities and vocabulary, we separately considered literacy activities in the respective heritage language and in the societal language, German, and accounted…
