Research has indicated that lexical richness is an important indicator of second language (L2) proficiency. However, most research has examined written, cross-sectional English L2 corpora and does not necessarily indicate how spoken lexical use develops over time or whether observed trends are stable across L2s. This study adds to previous…

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…

The paper applies language management theory to study the interactions of international with local workers (simple management) and language policies (organised management) in 10 Czech video game studios. By longitudinally interviewing foreign game developers from Central-Eastern and Western Europe, as well as North and South America, I identified…

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…

This longitudinal case study investigated the developmental trajectories of two participants enrolled in an ITA oral communication course at Purdue University. The course provides language support to the ITA population who play a crucial role in higher education programs in the U.S. (Gorsuch, 2016). Over four months (i.e., one semester), I…

This study explores the lexical profile of essays written by 48 advanced learners of second language (L2) Russian who participated in the Russian Overseas Flagship, an intensive year-long study abroad program designed to help students reach Interagency Language Roundtable (ILR) Level 3 proficiency in all skills. Using the lexical frequency profile…

In the present study, we sought to advance the field of learner corpus research by tracking the development of phrasal vocabulary in essays produced at two different points in time. To this aim, we employed a large pool of second language (L2) learners (N = 175) from three proficiency levels--beginner, elementary, and intermediate--and focused on…

This study examines language mixing in 26 Spanish-English dual language learners over the course of their first year of preschool. The children's patterns of language choice while interacting in monolingual language contexts were analyzed at age 3;6 and 4;5 to examine: (1) whether the frequency of language mixing changed during the year; (2)…

The Canadian Academic English Language (CAEL) assessment is a proficiency test for university admission. Most research has focused on the paper edition, not the recent computer edition (CE). Validity research on other proficiency tests found that relationships between proficiency scores and academic achievement measures can be tenuous because…

One of the products of globalization in sociolinguistics is the emergence of transnational regimes in language policy, in which power is exercised across boundaries of traditional nation states. This paper engages with audit culture, a transnational policy mechanism which involves the continuous evaluation of nation states' performance through the…

This study explored the development of L2 learners' interactional competence in Arabic when making requests. Combining a longitudinal and cross-sectional design, it closely examined how learners' language proficiency affected their use of multiple requests in daily-life interactions. Participants included L2 learners (n = 40) and Saudi Arabic…

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…

Linguistic complexity serves as an important measure of second language (L2) writing development. Complexity indices, however, rarely feature in the studies of learner languages other than English. Additionally, L2 writing studies have been criticized for the lack of consistency in defining proficiency. The current study addresses these gaps by…

This longitudinal study examined the development of narrative micro- and macrostructure in Japanese-English bilingual returnee children. Returnees are children of immigrant families who move to a foreign country, spending a significant portion of their formative developmental years in the foreign majority language context before returning to their…

This paper reports on a longitudinal study that investigated how international students' personal network mediated their pragmatic choices during studying abroad in China. Data were collected over a year through different ways, including Study Abroad Network Questionnaire, role-plays, retrospective verbal reports, ethnographic interviews and…
