Languages differ in their realization of the subject argument: non-null-subject languages, like English, require subjects to be phonologically overt; rather, null-subject languages, like Greek, allow the subject to be overt or null. This cross-linguistic difference can lead to the transfer of grammatical properties across languages during…

Assessing vocabulary knowledge is an important part of establishing language proficiency in bilingual children. The crosslinguistic lexical tasks (CLTs) provide a framework for testing vocabulary development in three-to-six year-olds using a standard procedure and comparable items for multiple languages. This study describes the development of the…

In second language acquisition, it is well known that an early age of onset and an extensive amount of naturalistic input are key elements promoting successful learning outcomes. What is less well known is what outcomes we can expect when the main source of these elements is full-immersion schooling, defined for the purposes of this study as a…

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…

We investigated the potential influence of implicit learning mechanisms on L2 morphosyntactic attainment by examining the relationship between age of onset (AoO), two cognitive abilities hypothesized to underlie implicit learning (phonological short-term memory and implicit statistical learning), and performance on an auditory grammaticality…

The present mixed-methods study examined the role of learner appraisals of speech tasks in second language (L2) French fluency. Forty adult learners in a Canadian immersion program participated in the study that compared four sources of data: (1) objectively measured utterance fluency in participants' performances of three narrative tasks…

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 examines English-speaking learners of Spanish and their pragmatic development of request forms during a six-week immersion program in Madrid, Spain. Elicited production and intuition data were analyzed, focusing on personal deictic orientation, directness evidenced by clause type, and the use of "por favor"…

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…

For the majority of people in Ireland, Irish is a second language acquired primarily through the schooling system. This study examined the reading strategies children used in response to English and Irish words (presented in isolation), through an analysis of their oral reading errors. Children in their 4th year of schooling attending…
