Yet, we have a limited understanding of the associations between family size, specifically the number of adults and siblings, and children's social communication skills, particularly in children from diverse linguistic environments. The present study examined the effects…

Using a national database, this study examined the relationship between the language of instruction models and the frequency of peer-mediated learning activity on English learners' reading achievement (N = 1,004). Results from the Multilevel Modeling (MLM) analyses revealed an interaction between the language of instruction and the frequency of…

Bilingual children often lag behind monolinguals on standardized measures of language acquisition, such as vocabulary tests. This bilingual lag could be related bilinguals' lesser experience with the target language relative to monolinguals. In this study, we predicted that sequential Mandarin-English bilinguals would perform worse than same-aged…

There is a growing number of children learning to read in bilingual environments, yet research on the uniqueness of reading acquisition in these bilingual children, particularly L1 majority bilinguals, is limited. With a sample size of 690 4th-grade students, this study investigated predictors influencing L1 Chinese reading in Chinese-English…

Using the Early Childhood Longitudinal Study Kindergarten Cohort (2010-2011), this study is the first to investigate predictors of kindergarten science achievement and growth across elementary school--English language proficiency (ELP), executive functioning, math and reading achievement, parent-engaged science and math activities, and classroom…

The present study examines the mechanisms of lexical case acquisition in Russian by two-to-five-year-old Russian monolingual (n = 54) and Russian-English bilingual children (n = 38). Participants performed a picture-based sentence completion task. Sentences were constructed to elicit production of real Russian words (n = 24) and nonce words (n =…
