Purpose: This study examined science achievement; science vocabulary knowledge; and the relationship between science vocabulary, language skills, and science achievement in school-age children with language/literacy disorders (LLDs) and typical language development (TD). Method: Thirty-nine sixth graders (11 with LLDs) completed standardized…

Shifting demographics in K-12 schools have increased Spanish-speaking Multi-Language Learners' (MLLs') enrollment across the United States. While literacy variations between MLLs and proficient English speakers have been studied predominantly with upper elementary students, there remains a need for more exploration among early elementary…

While it has been shown that socioeconomic status (SES) is important for children's literacy development in their first language (L1), less is known about its association with reading in a second language (L2). The present study examined the different effects of SES on the acquisition of reading in Chinese as L1 and English as L2 from ages 7 to…

This article explores the critical role of phonological awareness (PA) in early reading development, with a focus on young multilingual children. PA, the ability to detect and manipulate sounds in spoken words, is essential for literacy acquisition and is highly responsive to instruction. The article delves into the complexity of PA, its…

This study examines the intricate relationships between home language use, oral language skills (phonological awareness, morphological awareness, and receptive vocabulary), and literacy skills (word reading and spelling) in English and Chinese among young bilinguals. The sample includes 249 first-grade and 263 third-grade bilingual students in…

Research has established the link between socioeconomic status (SES) and children's reading development. However, the theoretical mechanisms underlying the association between them have yet to be fully understood. Moreover, few previous studies exploring the mechanisms tapped both first language (L1) and second language (L2) at the same time. In…

For preschool-aged children at-risk for literacy difficulties, we examined whether classroom and home environments were jointly associated with literacy skill gains and whether environments moderated response to intervention (n = 281). We first used a person-centered approach to characterize children's classroom and home environments, identifying…

Dual language learner children (DLLs) benefit from early childhood education (ECE) and learning multiple languages, but research has predominantly focused on English monolingual children, with limited insight on the ECE and early development of DLLs. This study investigated whether DLLs' developmental assets assessed at pre-k entry (i.e. English…
