Lexical proficiency in a second language (L2) has long been effectively assessed through the measurement of various lexical indices, or textual characteristics that act as observable indicators of such conceptual categories as lexical richness, diversity, sophistication, and fluency. While many studies have established links between these lexical…

Numerous empirical studies and syntheses have explored technology-mediated task-based language teaching (TMTBLT) (for example, Chong & Reinders, 2020; Kim & Namkung, 2024; Lai & Li, 2011; Ziegler, 2016), with findings highlighting the affordances of technology for interaction and its associated benefits. However, few studies have…

This two-phased study explored a corpus-driven, curriculum-based approach to assessing proficiency development of Mandarin Chinese in US universities. In Phase I, we developed an elicited imitation (EI) test based on the Chinese curriculum at a large US university. This test demonstrated higher psychometric qualities to (1) place L2 learners into…

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…

Macaro has stated that the choice between a monolingual, immersive, target language-only pedagogy versus a non-immersive, multilingual pedagogy is 'probably the most fundamental question facing second language acquisition (SLA) researchers, language teachers, and policymakers'. Recognizing that prior empirical work on monolingual versus…

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 article is the first large-scale study to document the speaking proficiency outcomes of intensive programs in less commonly taught languages in US higher education. Speaking proficiency was measured by pre- and postprogram ACTFL Oral Proficiency Interviews (N = 484) in 14 languages: Arabic, Bengali, Brazilian Portuguese, Hindi, Indonesian,…

This dissertation investigates the longitudinal development of Chinese language proficiency among students in a Chinese as a Foreign Language (CFL) Flagship Program at an American public university from 2014 to 2024. Using Bayesian multilevel regression models, this study assesses the trajectories of listening, speaking, and reading proficiency…

Reaching the Advanced level of proficiency in speaking is a common goal of second language learners, but data on advanced learners of less commonly taught languages such as Arabic are scarce. This mixed-methods study reports words-per-minute and type-token ratios for three ACTFL levels--10 Intermediate Mid, 10 Advanced Mid, and 8…

In the Basque Autonomous Community, besides the official languages Spanish and Basque, English is considered an important third language for internationally operating companies. However, employees are not believed to be linguistically well enough prepared, due to shortcomings in English language learning in the Basque educational system. The…

Bilingual speakers must acquire the phonemic inventory of 2 languages and need to recognize spoken words cross-linguistically; a demanding job potentially made even more difficult due to dialectal variation, an intrinsic property of speech. The present work examines how bilinguals perceive second language (L2) accented speech and where…

Due to the history of assimilation, power relations, and their sociolinguistic situation, the Sámi languages are categorized as endangered. The position of the Sámi languages in Sámi education is reviewed, and language immersion as a teaching method and as a means of language maintenance is discussed. Sámi language learning is described through…

This regional dossier aims to provide a concise, description and basic statistics about minority language education in a specific region of Europe.

After the United States emerged as the major world economic leader following World War II, language curricula for specific purposes in international business were put into practice at the college and university levels. This article documents the work of the major players in the development of coursework and materials for business languages for…

In this study, we explore native and non-native syntactic processing, paying special attention to the language distance factor. To this end, we compared how native speakers of Basque and highly proficient non-native speakers of Basque who are native speakers of Spanish process certain core aspects of Basque syntax. Our results suggest that…
