The present dissertation brings together research on heritage language acquisition and bilingual education and makes inroads into the limited research on heritage language development in school-aged bilingual children. This study explores how bilingual education, patterns of exposure, and lexical frequency shape adolescent Spanish heritage…

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…

Despite the increasing popularity of dual language education programs in Taiwan, limited research assesses their effectiveness. This study evaluated eight English Immersion Programs (EIPs) in Taiwan, representing a dual language education model, using the "Guiding Principles for Dual Language Education" (GPDLE) framework. Interviews with…

This study seeks to examine the success of voluntary immigrants in Grade 6 French immersion with a double comparison to Canadian-born (a) Anglophones and (b) multilingual students (children of voluntary immigrants). The findings, that show the immigrant students to outperform the other two groups in French and English, are explored through a…

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…

Grounded in the cross-linguistic influence(s) (CLI) literature, this study used objective measures to compare the use of English, lexical richness and syntactic complexity, and grammatical accuracy and fluency in the texts of three groups of Grade 6 French immersion students: Canadian-born anglophones (C-A), Canadian-born multilinguals (C-M), and…

We examined the effects of classroom bilingual experience in children on an array of cognitive skills. Monolingual English-speaking children were compared with children who spoke English as the native language and who had been exposed to Spanish in the context of dual-immersion schooling for an average of 2 years. The groups were compared on a…

In this article, we report two studies that compared the development of English and French language and literacy skills in French immersion students identified as native English speakers (EL1s) and English learners (ELs). In study 1, 81 EL1s and 147 ELs were tested in the fall and spring terms of grade 1. The EL1s and ELs had similar outcomes and…

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"…

Considerable research documents students' outcomes in dual language (DL) programs, but there is little examination of students' perceptions of bilingualism and its impact on students' cognitive functioning and social relationships, especially with comparative studies across different target languages and student backgrounds. This study, which…

This comparative case study (based on observational, interview, and picture-sort data) examines how teachers and students talk about cultural, linguistic, racial, and socioeconomic difference in two elementary Spanish-English two-way immersion programs. In addition, I analyze how those discourses are associated with both contextual conditions and…

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…

Early years' immersion education programmes can be either monolingual or bilingual, and their objectives can range from language maintenance and/or enrichment to early second language learning, depending on the context of implementation. Here we examine some of the key issues and policy concerns relating to immersion education in the early…

This paper examines two sociolinguistic lexical variables, "work" and "to dwell," in the spoken French of former immersion students in their first or fourth year at a bilingual university in Ontario, Canada. Their patterns of use are compared to those of non-immersion graduates in the same institution, to Ontario high school…

Will participation in a Dual-Immersion program increase students English language literacy compared to their mainstream classroom peers? Literacy scores on the DIBELS and WIDA Access were assessed over two years for 144 students to see if English Language Learners (ELL) are having more success in English literacy acquisition than their mainstream…
