This dissertation outlines three studies investigating linguistically diverse students' (including bilingual and monolingual students) language use and self-efficacy in writing. Bilingual students are those who speak a language other than English, including students with various levels of English proficiency and language experience. The first two…

While large language models (LLMs) continue to grow in scale and gain new zero-shot capabilities, their performance for languages beyond English increasingly lags behind. This gap is due to the "curse of multilinguality," where multilingual language models perform worse on individual languages than a monolingual model trained on that…

In an effort to address the needs of the fastest growing population at my school, I asked Latinx students to share their experiences of being in a monolingual English 2 classroom. Students also shared opinions about friendships, Latinx culture in school, and alternative methods of educating non-English speakers. Through action research we can…

Little evidence exists on how best to support children's alphabet knowledge, which is a foundational early literacy skill. In this study, I investigated the impact of multisensory alphabet instruction on the alphabet learning of English monolingual and emergent bilingual (EB) children aged 3:5 to 5 years old. My primary aim was to examine whether…

The academic achievement of Hispanic students is not increasing as much as the population is in schools across the United States. Although existing research explores the Hispanic achievement gap, none solely compares the relationship between Hispanic multilingual (ML) and Hispanic non-multilingual (non-ML) students. As the Hispanic population…

Understanding speech in an accent or dialect different than one's own can be challenging. McLaughlin and Van Engen (2020) were the first to quantify this increase in listening effort using Task Evoked Pupillary Response (TEPR), a common measure of cognitive arousal. They found that monolingual, English speaking adults' pupils dilated more quickly…

This dissertation investigates the development of cross-linguistic transfer in the use of strategies to repair preconsonantal word-external empty onsets (i.e., /C#V/) in Spanish heritage speakers. The main focus of this work is to analyze the use of /[glottal stop]/-epenthesis as a strategy to repair empty onsets, as its use is asymmetrical in the…

This dissertation explores clear speech which is defined as a specific speaking style people adopt when fluent communication could be compromised for various reasons. Although acoustic properties and their perceptual benefits of clear speech produced by monolingual speakers of English are well documented, there has only been a small body of past…

"'English is Unavoidable': The Implementation of Multilingual Writing in Foundations Writing, General Education, and Writing Across the Curriculum" reports on a longitudinal, qualitative study of six administrators and one multilingual student who were involved in three institutional writing initiatives during a time of major…

This dissertation critically examines the Colorado Reading to Ensure Academic Development Act (READ Act) through the lens of Critical Discourse Analysis, focusing on the discursive construction of the Act and its impact on educational opportunities for multilingual learners. The study explores the role of power and knowledge in shaping the READ…

For Chinese students, studying in a country with different cultural components and language structures is challenging. Compared to English, the Chinese prefers shorter and simple sentence structure and allows for two sentences to be stated side by side. Different sentence structures in Chinese may influence native-Chinese readers' understanding of…

Due in part to its complex nature, there is still much to uncover in the investigation of the neural processes that contribute to synchronization between speakers and listeners during communication in the context of social cognition, specifically between native and nonnative English speakers and listeners. This study used a novel method of…

Previous research has shown that language learners tend to produce fewer and less-natural multi-word sequences (MWSs) compared to native speakers of the same language. In the present study, collocational processing was investigated in a sentence reading task. Specifically, the familiar collocations were predicted to modulate the P3 mean amplitudes…

Although changes in the identification of dyslexia have shifted in recent years, the rate of identification of dyslexia for English Learners (ELs) continues to lag behind that of monolinguals. Using a large sample of student data reported in the Public Education Information Management system (PEIMS) across two school years (2013-14 and 2019-20;…

This qualitative case study aimed to explore the role culture plays in influencing teachers' educational practices and literacy instruction with English language learners (ELLs). It sought to discover how monolingual teachers' experiences, successes, and barriers influence literacy instruction with ELLs in an elementary school in the midwestern…
