Success in mathematics contributes to children's future career and lifelong financial security. There have been reports that dual-language education conveys academic advantages in mathematics achievement, although there is debate. This study aimed to investigate whether dual-language education benefits children's mathematics achievement and…

This study explored the development of oral narrative retell proficiency among Mandarin Chinese-English dual language immersion (DLI) learners in Utah. The study compared the younger and the older DLI learners' oral narrative retelling production in order to provide information regarding the Mandarin narrative developmental trend of the DLI…

Models of reading development point to a role for knowledge about the orthography quite late in children's reading development; here we explore the contributions of early orthographic knowledge -- of the features of print -- to word reading development between kindergarten and Grade 1. We did so in a longitudinal study of 93 emergent bilingual…

Using the 2.4-million-word written Spanish subsection of the Corpus of Utah Dual Language Immersion, collected from a large-scale standardized writing assessment of K-12 Spanish second language (L2) students, this study focuses on lexical complexity as operationalized by three measures: lexical diversity, lexical density, and lexical…

This study reveals hitherto overlooked effects of age of onset (AO) in immersive school contexts, using multiple measures over time so as to focus on fluctuations and trends in individual data. The second language (L2) English development was studied in 91 children who received 50-50 content and language integrated learning (CLIL) instruction in…

Purpose: The study examined the contributions of Spanish and English oral narrative skills to English reading among 95 early elementary dual language learners (DLLs) from Spanish-speaking homes in the United States. This sample of first- and third-grade DLL children attended Spanish-English dual language immersion programs and received language…

Elementary French immersion (FI) language arts teachers often organize instruction around small learning groups. Students rotate through learning stations/centres and work independently with their peers on L2 literacy skills. This study examined how principles of task-based language teaching (TBLT) can be used and/or adapted to further support…

The purpose of this study was to create and prototype a dual language assessment task that allows young English learners to use their entire cadre of linguistic resources (language and non-verbal resources) to obtain information about their emergent language abilities. We developed a dual language assessment task in which students described a…

I conducted 2 experiments in which I tested the effects of a reader immersion procedure on the technical reading comprehension responses to print stimuli for 4 kindergarten students and 3 first grade students. The participants selected for this study textually responded to words at a rate of 80 words correct per minute with 0 incorrect words per…

Working memory (WM) is a recognised component of executive function and has undergone scrutiny in terms of bilingual and monolingual performance comparisons. Research to date, however, has not consistently replicated the presence of bilingual advantage. The present study examined short-term (STM) and WM in immersion-educated children and a matched…

Schools in Ireland vary in how they introduce reading in the two official languages, Irish and English. There is particular variability within immersion (Irish medium) schools. Some introduce Irish reading first (IRF) and others English reading first (ERF). This study compared the development of Irish and English skills in children attending…

In several studies it is highlighted that the early acquisition of a language in the home results in phonetic and phonological benefits, and that it is not uncommon for early learners to achieve native-like pronunciation in their heritage language. However, most of these studies have been carried out with bilinguals. The present contribution aims…

The current study, with 409 fourth graders in two-way immersion programs, explored the writing self-perceptions of native English and native Spanish speakers and the relationship between self-perceptions and writing performance. An adapted version of the Writer Self-Perception Scale (WSPS) was administered along with a writing task. Native English…

Language immersion students' lexical, syntactic, and pragmatic competencies are well documented, yet their phonological skill has remained relatively unexplored. This study investigates the Spanish vowel productions of a cross-sectional sample of 35 one-way Spanish immersion students. Learner productions were analyzed acoustically and compared to…

This study examined metalinguistic awareness in children who were becoming bilingual in an immersion education program. The purpose was to determine at what point in emerging bilingualism the previously reported metalinguistic advantages appear and what types of metalinguistic tasks reveal these developmental differences. Participants were 124…
