Advances in Natural Language Processing (NLP) over the past decade have largely been driven by the scale of data and computation used to train large neural network-based models. However, these techniques are inapplicable to the vast majority of the world's languages, which lack the vast digitized text datasets available for English and a few other…

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…

Although study abroad is an established research context for second language acquisition, the emotional experiences of U.S. students learning less commonly taught languages, such as Czech, require further research, particularly in settings where these languages lie outside students' primary academic pursuits. This study explores U.S. students'…

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…

Background: Augmented reality can provide a 3D virtual experience, widely used in modern education. However, the impact of these applications on the underdeveloped tribal community has yet to be investigated. To our knowledge, no markerless augmented reality application has been developed especially for learning the language of the Bodo tribe.…

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 paper investigates the role of supplementary schools as grassroots educational initiatives whose reach extend beyond individual educational trajectories for minoritized youth. We examine how these schools serve as community forces, emphasizing the importance of resources and relationships. Drawing on the theoretical frameworks of funds of…

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…
