This study examined the influence of linguistic input on the development of productive and receptive skills across three fundamental language domains: lexico-semantics, syntax, and phonology. Seventy-one (35 female) Basque-Spanish bilingual children were assessed at three time points (Fall 2018, Summer 2019, Winter 2021), between 4 and 6 years of…

Research on the effects on early bilingualism on reading development is scarce. Here, we tackle this question by investigating whether the exposure to dual-language contexts (use of two languages in the same conversational situation) induces a boost in phonological and reading performance through more balanced spatial auditory attentional skills.…

This article examines the impact of within-class age differences on educational outcomes, using students' birth months in Madrid's primary schools as a natural experiment. Employing a regression discontinuity design, we analyze third-grade students to investigate these age-related effects. Additionally, we explore whether early childhood education…

In this preregistered study, we used latent change score models to address two research aims: (1) whether preschool-aged children's language gains, over a year of early childhood education, were associated with later performance on state-mandated, literacy-focused kindergarten readiness and Grade 3 reading achievement assessments; and (2) whether…

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…

Early literacy proficiency is a crucial predictor of later reading success, but research in this area often overlooks the unique challenges faced by English Learners (EL). This study addressed a significant gap in the literature by investigating the relationships between Dynamic Indicators of Basic Early Literacy Skills (DIBELS) scores, English…

Reading comprehension and arithmetic skills are essential abilities for children, particularly at the early career. Examine the link between language proficiency and numeral information process amongst primary school children. This study examines numeral comprehension in 600 Chinese primary second graders with different levels of decoding and…

Using data from a longitudinal German large-scale study and structural equation modeling, this study investigated the effects of different dimensions of the early home learning environment (HLE) as well as the effect of language-related preschool quality at the age of 3 to 5 years on students' later school-relevant language proficiency (as…

There is an interdependent relationship between academic proficiency and English language proficiency. This quantitative, correlational study examined the threshold hypothesis in relation to two required summative assessments for third--eighth-grade multilingual learners in South Carolina. Third-grade multilingual learners from a large school…

The research in this volume takes account of the context of policy promoting Chinese as a second language (CSL) in several countries and regions, (Australia, East Asia and South-East Asia), and the wider social context of multilingual and multicultural societies. Furthermore, this book reports results of two research studies which investigated how…

This study explores how kindergarten students from a multilingual sample (n=131) representing 23 different languages differ in response to intervention, based on their skill in mathematics and domain general cognitive skills. Analyses for this study indicate significant correlations between initial math skill, phonological memory, working memory,…

Many schools now screen students for dyslexia in early grades. However, there are valid concerns that these screeners may be biased or ineffective at screening students who are not yet proficient in English (i.e., English Learners; ELs). The present study examined the performance of 54 first graders on a dyslexia screener. Results showed that…

The relationship between reading comprehension and reading fluency for linguistically diverse learners continues to be a topic of education research. The problem is third and fourth-grade second-language learners possess adequate reading fluency skills but demonstrate distinct reading comprehension difficulties compared to native English-speaking…

It has been proposed that an implicit learning deficit explains the difficulties with grammar commonly observed in children with Developmental Language Disorder (DLD). The present study further investigates this link in two ways. Firstly, we investigate whether kindergartners with DLD have more difficulties with preposition understanding and…
