Morphological knowledge is known to be positively associated with reading ability. However, whether morphological knowledge affects children's learning of new orthographic representations is less clear. Purpose: This study aimed to investigate morphological effects on orthographic learning in English, and whether this effect, if any, is different…

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 compared language minority bilingual (LMB) second graders with two groups of monolingual peers (with comparable low SES or with high SES) in a set of literacy skills (reading fluency, spelling, reading and oral comprehension) tested in the target school language (L2 for bilinguals). The aim was to disentangle the roles of bilingualism…

Purpose: Math word problem solving, a form of reading comprehension, is complicated by mathematical lexical ambiguity (e.g., the word "difference" can mean "dissimilarity" in everyday discourse but "the answer in a subtraction problem" in math). This study examined the role of mathematical lexical ambiguity in math…

Nowadays, classrooms include children coming from a wide range of cultures and speaking different languages. Teachers are therefore challenged to create appropriate learning opportunities for very diverse children. The current study examined the unique contribution of general classroom interaction, individual teacher-child interactions and…

Despite much research examining whether bilingual individuals demonstrate superior executive function (EF) skills compared to monolinguals, the purported bilingual advantage remains controversial. One potential reason for discrepant findings across studies examining the bilingual advantage is the difficulty in matching monolingual and bilingual…

Using a large sample of longitudinal assessment data from children in publicly funded infant/toddler care, preschool, and kindergarten (analytic N = 453,468), this study modeled language and literacy trajectories from early infancy through kindergarten for dual language learners (DLLs) from homes representing many different languages and their…

This study investigated the vocabulary development of children (N = 547) from linguistically and socioeconomically diverse classrooms in Germany from age 3 in preschool to age 7 in Grade 1. The results showed that for dual language learners (DLLs, n = 107) growth rates in their German majority language skills varied over classrooms. Compared to…

Providing first language (L1) translations in L2 vocabulary interventions may be beneficial for L2 vocabulary learning. However, in linguistically diverse L2 classrooms, teachers cannot provide L1 translations to all children. Social robots do offer such opportunities, as they can be programmed to speak any combination of languages. This study…

Environmental sources of variance in the Italian vocabulary and reading skills of bilingual primary school children from immigrant families (or language minority bilingual children (LMBC)) in Italy were investigated, and the LMBC's skill levels were compared to those of their monolingual classmates. A total of 140 children from the first, third,…

The texts students encounter are becoming increasingly complex and multimodal. There remains a need to understand the semiotic resources students draw upon to make meaning with these multimodal texts. This study draws on social semiotics as a frame to explore the ways in which eight first graders with a wide range of literacy proficiency levels…

Language is commonly positioned as an economic resource. Recent debates have argued that policy interpretations of language as economic resource can potentially undermine language positioning and reduce understanding of the cognitive, cultural and social benefits of language learning. In monolingual policy contexts, such a positioning means that…

This study examined the role of science domain knowledge, reading motivation, and decoding skills in reading comprehension achievement in third-grade students who are English learners (ELs) and students who are monolingual, using a nationally representative data set. Multigroup probit regression analyses showed that third-grade science domain…

Foreign language learning is generally not required in the United States, despite its link to various cognitive and social benefits later in life. Students who speak a home language different from the instructional language of school may experience unique benefits when learning additional languages in school. The present study examined whether…

Bilingual children with a limited command of the second language (L2) often yield unsatisfactory results in L2-based non-word repetition tasks (NWRT) for the assessment of working memory. In this study, monolinguals (MO) and bilinguals (BI) of preschool age acquiring German were compared in regard to their performance on German-based NWRT to…
