This study investigates the longitudinal development of language attitudes towards Catalan and Spanish over a five-year period in the transition from primary to secondary education of a sample of students (N = 1,143) in Catalonia and Aragon. Two research questions were investigated: (1) How do language attitudes develop over time? and (2) How do…

The purpose of this qualitative research study is to portray the complex language practices of multilingual children when learning mathematics. To do so, I draw on data collected as part of a three-year research study that was designed to understand the relationship between young children's language use and mathematics learning, focusing on…

This book gives an overview of the linguistic development of Korean-English bilingual children living in the US. It provides a detailed longitudinal account of English and Korean acquisition in early childhood, offering a close examination of Korean-American children's code-switching and morphology and syntax development during a time when their…

This study examined the role of parents' early home language use in the English reading development of emergent bilinguals (N = 3,058) and how their relations are moderated by children's oral English language proficiency using longitudinal data from kindergarten to eighth grade (ages 6-15 years). Results from multi-group latent basis growth models…

This study longitudinally examined the effects of cognitive and sociopsychological individual differences (aptitude, motivation, personality) and the quantity and quality of second language (L2) experience on L2 speech gains in naturalistic settings. We elicited L2 spontaneous speech from 50 Chinese learners of English at the beginning and the end…

Many second language (L2) learners participate in study abroad (SA) experiences believing their choice will be synonymous with increased interaction in the L2, from which enhanced linguistic gains will ensue. Nonetheless, one open question is whether SA participants actually engage in sustained L2 interaction while they are abroad. This paper…

The current study quantitatively applies Spolsky's triangular framework of language policy, including beliefs, practices, and management, to the family domain by investigating language policy in multilingual families in Belgium's Flemish Community. Firstly, we examine whether the three components in fact call for an independent description and…

This study describes academic literacy development during mid-adolescence, when learners need to adjust to the demands of academic discourse as a gateway to linguistic adulthood. Unlike most research to date, which is cross-sectional and detached from disciplinary content, this study provides a two-year longitudinal description of academic…

This article discusses a comparison of the two focal primary school third-grade Korean bilingual students' language use with their previous language use when they were first-graders by examining their heritage language (HL) use at a Korean language school. For children of immigrant families in the U.S., there has been a pervasive hypothesis that…

This longitudinal inductive research unpacks the process of African post-secondary students' Chinese language identity (CLI) with the purpose of exploring a model of CLI development. We traced how 12 multilingual African students developed their CLI during the first year in a Chinese university. Data coded from three rounds of interviews conducted…

This paper examines evidence for relationships among individual differences (IDs) in L1 achievement, L2 aptitude, and L2 achievement. It begins by providing an overview of my academic journey from L1 educator to L2 researcher and explains the development of the Linguistic Coding Differences Hypothesis (LCDH). Next, I review Peter Skehan's…

Despite the growing body of studies on collocation learning in SLA research, there are hardly any studies taking the perspective of the individual learner or studies that have examined the effect of individual differences. This study--a qualitative component of a mixed-methods longitudinal project--presents an in-depth exploration of the intro-…

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 longitudinal research presents case studies of three English as a foreign language (EFL) student teachers showing their development regarding target language (TL) use, taking into account both the amount of TL use and the classroom situations the TL is used in. Additionally, the factors that influence their TL use are discussed. The data…

This paper explores the use of creative techniques in a study of the experiences of Russian-speaking linguistic-minority migrant children in English state-funded primary schools at Key Stage Two (7-11 years old). The methodology is based on an interpretative paradigm using a qualitative research approach: a longitudinal multiple-case study with…
