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…

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 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…

This study focused on investigating the background, experiences, challenges and training of current online language teachers. An online survey was sent and completed by a total of 264 current online language teachers consisting of a total of 40 questions. Findings show online language teachers are highly experienced in face-to-face classrooms as…

Learner autonomy is a fundamental phenomenon in the teaching and learning of languages. The growth of digital technology and the Internet appears to have changed the manifestation of learner autonomy, particularly in Less Commonly Taught Languages (LCTLs). The purpose of this phenomenological research study was to examine the experiences of LCTL…

Language instructors play a decisive role in adult language learners' learning and retention of vocabulary through planning, selection, and teaching of vocabulary and strategies. However, some professional language schools lack extensive teacher-training programs that prepare instructors with the skills required to select and teach vocabulary,…

Language and culture teaching has always been a complex and challenging task. For many educators, their teaching experiences are rooted in their earlier preparation, their classroom situations and their curriculum. In this study, indigenous educators recount their lived experiences with teaching their language and culture at a distance. These…

Studies of informal language learning and self-instruction with online materials have recently come into prominence. However, those studies are predominantly focused on more commonly taught languages and there is a gap in the literature on less commonly taught languages (LCTL), precisely the languages that are often studied outside of formal…
