This dissertation is a quantitative analysis of language proficiencies through the lens of the dynamic model of multilingualism, using survival analysis to evaluate time until thresholds of foreign language proficiency are reached and nonparametric tests (Wilcoxon signed rank and Kruskal-Wallis) to compare proficiencies at distinct time intervals…

This dissertation explores the experiences of adult English as a Second Language (ESL) learners in an Adult Basic Education (ABE) program. ABE/ESL learners are a unique but integral population within the language learning community and are largely excluded from the scholarly discourse. Research in the context of language learning and instruction…

Mastering the phonological aspects of a second language (L2) poses significant challenges for adult learners, often affecting their intelligibility in acquiring that language (Derwing, Munro, & Wiebe, 1998).

Mobile-assisted language learning (MALL) offers the advantage of flexible language support, enabling learners to choose when and where they learn and the methods that suit them. The constant connectivity of modern mobile phones allows learners…

Adult learners of a new language (L2) tend not to achieve target-like knowledge and performance, so the cognitive status of L2s has long been debated. While monolingual native (L1) speakers robustly apply their grammatical knowledge to input as it unfolds, there are competing claims about whether L2 speakers also do so reflexively (Dekydtspotter,…

In this three-paper dissertation project, I explore how 'English' becomes a recognizable object within the context of adult ESOL education. Building on scholarship on named languages (Garcia, 2019; Makoni & Pennycook, 2006), the historical construction of languages (Bonfiglio, 2010; Irvine & Gal, 2000), and raciolinguistic ideologies…
