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…

This study explored changes in English language proficiency and several non-linguistic factors during four years of English medium instruction (EMI) in two academic disciplines in a Turkish university setting. Moreover, it also investigated whether changes (if any) had a predictive impact on the academic success of EMI students. In addition,…

Background: Despite extensive research examining features of adolescents' ego-identity development, little research has demonstrated patterns of ego-identity development and its relationship with various individual and environmental factors that are theoretically important for identity development. Objective: The current study investigated…

In this preregistered, longitudinal study of early code-switching, 34 US-born, Spanish-English bilingual children were recorded with a bilingual family member at 2;6 and 3;6, in Spanish-designated and English-designated interactions. Children's Spanish and English expressive vocabulary and their exposure to code-switching were measured through…

This study examined the longitudinal prediction of decoding, oral reading fluency (ORF), and bilingual language proficiency (BLP) on student reading comprehension (RC) outcomes in Spanish and in English. Participants were first-grade Latinx students attending bilingual programs. Findings indicated that BLP initial status and gains were significant…

This study reports on a conceptual model that provides insight into the relationship between English reading proficiency and academic performance of first-year science and mathematics university students in Ghana, and an empirical test of that model. Longitudinal data were acquired from a sample of 133 students. Using three different mediation…

This study examined the longitudinal prediction of decoding, oral reading fluency (ORF), and bilingual language proficiency (BLP) on student reading comprehension (RC) outcomes in Spanish and in English. Participants were first-grade Latinx students attending bilingual programs. Findings indicated that BLP initial status and gains were significant…

The United States faces high demand for science, technology, engineering, or mathematics (STEM) professionals and a scarce supply of individuals who pursue STEM careers, especially minority populations in the U.S with proficiency in a language other than English. The primary goal of this research was to determine the impact of use of Spanish in…

Hispanic adolescents have high expectations for their own educational attainment, but educational attainment outcomes for Hispanic young adults are relatively low on average. Limited scholarship links Hispanic adolescents' educational expectations with attainment in adulthood. Using a longitudinal within-group approach, the authors examined…

This study investigates the multicomponential nature of L2 Arabic writing by adapting a number of direct measures of linguistic "complexity," "accuracy," and "fluency" (CAF) to the measurement of written Arabic texts produced by L2 Arabic learners and Arabic Native Speakers (NSs). Previous studies of L2 writing have…

In a longitudinal design, 51 low-achieving adolescents' development in writing proficiency from Grades 7 to 9 was measured. There were 25 native-Dutch and 26 language-minority students. In addition, the roles of (1) linguistic knowledge, (2) metacognitive knowledge, and (3) linguistic fluency in predicting both the level and development of writing…

In a nation where monolingualism predominates, heritage language (HL) has been downplayed as less important in educational contexts in the U.S. Disproportionately little attention has been given to the role of HL in language minority (LM) students' attendance to postsecondary education (PSE) (cf. Brutt-Griffler, Janina, and Manka Varghese, eds.…

The current study longitudinally examined the influence of aptitude on second language (L2) pronunciation development when 40 first-year Japanese university students engaged in practice activities inside and outside English-as-a-Foreign-Language classrooms over one academic year. Spontaneous speech samples were elicited at the beginning, middle,…

Background: Little empirical research examines the process in which home literacy environment (HLE) in toddlerhood is associated with preschoolers' vocabulary and decoding skills using a large-scale dataset. Objective: The purposes of the current study were to (a) examine the differential effect of HLE in toddlerhood on preschoolers' vocabulary…

The relation of rapid automatised naming (RAN) to word recognition may depend on the phonological regularity of the orthography. This study examined differential contributions of RAN to reading and writing in Korean alphabetic Hangul, logographic Hanja (Chinese) and English as a second language among 73 fifth graders in Korea across 1?year. RAN…
