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…

Purpose and Method of Study: Using a phenomenological approach, this study explored in-depth the lived experience of United States Military Academy (USMA) cadets participating in a semester abroad program (SAP) to increase knowledge of how such experiences impacted their intercultural effectiveness development. This study added to the knowledge…

English language (EL) students' English language proficiency (ELP) scores directly impact a school district's College and Career Ready Performance Index (CCRPI) score, measuring whether Georgia meets accountability requirements. English language proficiency for English language learners (ELLs) is measured by the ACCESS for ELLs assessment. The…

In recent years, Third Language Acquisition (TLA) in Cross-Linguistic Influence (CLI) research has been debated regarding background languages' impact on learning a target language. While Second Language Acquisition (SLA) research often emphasizes the primary influence of the first language (L1) on the target language, it does not discount the…

Learner corpus research has expanded from focusing primarily on English as a second language (L2) to include languages such as L2 Spanish, reflecting the growing importance of corpus linguistics in second language acquisition (SLA) research. In this context, and because prompts are the means by which learner corpora gather their texts, it has…

In the ever-changing digital era, the surge of online informal language learning platforms has revolutionized the way we learn new languages. This dissertation delves into the critical role of interactional feedback (IF) in synchronous computer-mediated communication (SCMC), a cornerstone for optimizing these digital learning spaces. Anchored in…

This dissertation explores first language (L1) transfer and second language (L2) transfer processes and models, such as the full transfer/full access model (FT/FA), the representational deficit/interpretability hypothesis, and the feature reassembly hypothesis (FRH). The typological proximity model (TPM), the cumulative enhancement model (CEM),…

The United States government is perennially in need of employees with proficiency in critical foreign languages to communicate with foreign counterparts and maintain relationships worldwide. In order to fulfill this need, the government devotes significant resources training federal employees to advanced levels of language proficiency through…

During the era of accountability in K-12 schools in the U.S., school leaders' and teachers' responsibilities concerning language proficiency assessments extend beyond test administration and determination of eligibility for services. State and federal accountability systems challenge educators and school leaders to use language assessment results…

The number of English language learners (ELLs) has increased. The problem is ELLs in a middle Tennessee Charter School network meet challenges in achieving English proficiency, thus limiting academic and social prospects. The purpose of this quantitative correlational study was to determine if there was a relationship between leader-led…

The English proficiency gap is one of the most significant problems for young students in South Korea as it widens inequality by limiting opportunities for their future. One unique learning center, located in the under resourced area in South Korea, has been available at cost-free to enhance language development. This qualitative case study aims…

To date, most classroom-based research into the learning of a third language (L3) in the US has examined patterns of acquisition among various groups of bilinguals. Situated mainly within the context of "Portuguese for Spanish Speakers" (PSS), studies typically group learners based on the sequence / age of onset of their main background…

This project examined the acquisition of third person accusative clitics in Spanish by Chinese-speaking learners. Specifically, it focused on the role of cross-linguistic influence and patterns of language exposure and use in the acquisition of the syntactic and semantic properties constraining the production and intuition of overt and null…

This dissertation contributes new data to the debate on the source and manner of transfer in third language (L3) acquisition. The "L1 Status Factor" (L1SF, e.g., Hermas, 2010; Leung, 2002; Lozano-Pozo, 2003) maintains that the transfer source is the native language (L1), whereas the "L2 Status Factor" (L2SF, Bardel & Falk,…

For decades the importance of second language learning has been a topic of research, especially the investigation of early language acquisition and its continuity. The significance of learning a second language proves to be fundamental for students' growth, particularly concerning globalization within a society that is becoming increasingly…
