The increasing diversity in American public schools presents challenges to teachers and administrators. Current methods of reading instruction for English language learners (ELLs) have been ineffective to meet their needs in acquiring vocabulary. Meanwhile, the amount of time afforded ELLs to become proficient with grade-level vocabulary presents…

While language aptitude and motivation are considered to be important contributors to second language (L2) attainment, two major gaps in the past research have been (1) a lack of nonlinear models stemming from a naive and tacit assumption that learning outcomes are linearly related to their predictors, and (2) a lack of unified and integrative…

This study investigates the effects of four online vocabulary tasks on second language (L2) vocabulary acquisition among learners of different proficiency levels. While tasks are widely used to support L2 vocabulary learning, the efficacy of a task depends on the interplay between task and learner factors. Thus, choosing an appropriate task…

Acquisition of the perfective marker "-le" in Mandarin Chinese is a daunting task for second language learners.

Within the past few decades, notable contributions have been made in heritage language education research that continued to gain ground in language pedagogy and teaching practices (e.g., Davila, 2017; Valdes, 2000; Fishman, 2001; Kelleher, 2010; Polinsky & Kagan 2007). This dissertation is guided by translanguaging and social identity, two…

The present dissertation intends to investigate the syntactic nature and L2-acquisition of passive sentence structure in two Romance varieties, Italian and Spanish.

Oral communication skills are vital for adult English language learners, especially in daily activities and when securing employment (Parrish, 2015). Pronunciation instruction has been shown to improve learners' intelligibility and communication abilities (Darcy & Rocca, 2022; Thomson & Derwing, 2015), underscoring the significance of…

Since corpus linguistics gained popularity as a methodology in the latter half of the 20th century, second language acquisition research has seen the emergence of work investigating formulaic language, such as idioms, lexical bundles, and collocations. A collocation is a string of words that co-occur more routinely than probability would predict,…

This case study explored Spanish-speaking educators' perceptions and experiences of dual-language immersion (DLI) professional learning (PL). The study aimed to understand how PL offerings could best support and meet the needs of DLI Spanish teachers' best practices in the target language. The perceptions and experiences of seven Spanish DLI…
