This study evaluates the extent to which syntactic awareness contributes to reading comprehension in English-French bilinguals, considering both the potential for a direct relation, as well as an indirect one, through word reading. Participants were 146 first-grade students enrolled in early French immersion programs in Canada. While the children…

Chinese as the medium of instruction (MOI) is used across the curriculum for early childhood education in Hong Kong; however, kindergartens with non-Chinese speaking (NCS) students adopt different MOI, in which English remains an integral part of learning and teaching, to cater to the needs of NCS students and their families. The present study…

Guided by Dynamic Systems Theory (DST) and multidimensional perspectives on individual differences (IDs) in instructed second language (L2) learning (e.g., Larsen-Freeman, 2014; Sun & Zhang, 2020), this longitudinal mixed-methods study focuses on three conceptually different categories of L2 learners' IDs: working memory (WM), motivation, and…

This qualitative case study explored the perspectives of school administrators on implementing structured English immersion (SEI) and dual-language bilingual education (DLBE) programs serving emergent bilingual learners at one urban Arizona elementary school. Using a sociocultural policy perspective, I analyzed findings from a series of interviews…

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…

We investigated spelling errors in English and Spanish essays by Spanish-English dual language learners in Grades 1, 2, and 3 (N = 278; 51% female) enrolled in either English immersion or English-Spanish dual immersion programs. We examined what types of spelling errors students made, whether they made spelling errors that could be due to…

The following article is an adapted and abridged excerpt from The Language Immersion Life: A Guide for Families by Millie Park Mellgren (2017). This book features answers to the most common questions Dr. Mellgren was asked as an elementary immersion principal. The volume features commentary and data gleaned from surveys given to hundreds of former…

The purpose of this multiple-paper dissertation is to design a digital game and stealth assessments within the game to assess young second language learners' Chinese reading proficiency. In Chapter 2 (Paper 1), I describe the game designed for this dissertation and how it was implemented in a dual language immersion classroom. This study found…

The current study examined cognitive effects of two pathways of second language (L2) acquisition longitudinally in Chinese speakers learning English in an L2-dominant environment. Thirty-nine participants who attended an intensive 10-week English course (L2-instruction group) were compared to 38 participants who attended regular university courses…

This paper addresses the interactional dynamics of one bilingual, two-way immersion classroom where children came from diverse linguistic, cultural, racial, and socioeconomic backgrounds. Based on an ethnographic discourse analytic study of one kindergarten TWI classroom, I analyze interactional data using participant frameworks as the unit of…

There is currently much controversy surrounding the cognitive advantages that are often associated with bilingualism, especially regarding the so-called executive control advantage. Recently, it has been suggested that bilingualism emerging from immersion education may not lead to an advantage in executive control, but rather to an improvement…

French immersion (FI) programs in Canada have historically served predominantly Canadian-born, English-speaking students and families in their endeavour to learn both of the country's official languages, French and English. However, FI programs are becoming increasingly culturally and linguistically diverse as a result of increased global…

Conceptualizations of language as translanguaging (Otheguy, García, and Reid 2015) help us to render wholeness out of languages and groups of speakers socially constructed as distinct. Yet in practice teachers are still compelled to identify students by dichotomous institutional labels for discrete proficiencies in named languages: identity labels…

We examined spelling errors patterns, cohesive ties, and syntax features in English and Spanish essays written by Spanish-English emergent bilinguals in Grades 1, 2, and 3 (N = 278; 51% female) enrolled in either English immersion or English-Spanish dual immersion programs. In Study 1, we addressed whether students made consistent spelling errors…

This dissertation draws on both qualitative and quantitative approaches to investigate the linguistic practices of teachers and children who are learning Mandarin Chinese as a Heritage Language (CHL) in two dual immersion preschools in California. CHL children have been interpreted as novice members in local speech communities who actively explore…
