Learning to read is a fundamental skill that is understudied among children who hear more than one language at home. A particular limitation in the extant literature is that the samples are often Spanish-dominant and come from low-income households. This literature has evidence that Spanish skills -- both language-specific (i.e., vocabulary) and…

This dissertation investigates the impact of cross-modal binding on word reading skills among English Language Learners (ELLs). Using Baddeley's updated working memory model, which includes the Episodic Buffer, this study examines how the ability to bind visual and phonological information in memory influences the reading development of ELL…

Bilingual children, the majority of whom are Spanish-English learners, now constitute over a third of the preschool population in the United States (Migration Policy Institute, 2021). Bilingual children and their families face multiple barriers to high-quality early childhood education, which are largely due to the underutilization of culturally…

The purpose of the study was to investigate whether intrinsic motivation, extrinsic motivation, task value, metacognitive self-regulation, self-efficacy for learning, and cumulative GPA predicts academic success among college students enrolled in remote, asynchronous Elementary Spanish I and II courses. The study was conducted during the Summer…

This dissertation explored whether unnecessary linguistic complexity (LC) in mathematics and biology assessment items changes the direction and significance of differential item functioning (DIF) between subgroups emergent bilinguals (EBs) and English proficient students (EPs). Due to inconsistencies in measuring LC in items, Study One adapted a…

As grit has been associated with elements of academic success throughout the literature, it was of interest to the current study to analyze grit within the context of online, international ESL students enrolled in an American university. Thus, this study examined the predictive properties of grit (using both Spearman rho and stepwise regression…

The study abroad (SA) experience is often viewed as an opportunity to gain proficiency in a foreign language due to immersion in the target language and culture. Nevertheless, the increased amount of research conducted on SA over the last two decades indicates that it does not necessarily lead to gains in all areas (Collentine & Freed, 2004;…

A great deal of the research on cross-linguistic phonetic influence demonstrates that a speaker's knowledge of their first language (L1) significantly affects their ability to perceive and produce sounds in any other language. While current studies show that cross-linguistic transfer occurs at the L3 level, some research suggests that properties…

Young children's emergent literacy skills, particularly phonological awareness (PA) and alphabet knowledge (AK), are two of the strongest predictors of future reading skill. There is limited research evaluating the effectiveness of emergent literacy interventions on the dual language PA and AK skills of at-risk Latino preschoolers who are Dual…

The purpose of this study was to investigate the relationship between personality types and second language acquisition. The study addressed a problem that is inadequately investigated in foreign language acquisition research; specifically, personality traits as predictors of language learning in college students studying Spanish as a foreign…

The United States faces high demand for science, technology, engineering, or mathematics (STEM) professionals and a scarce supply of individuals who pursue STEM careers, especially minority populations in the U.S with proficiency in a language other than English. The primary goal of this research was to determine the impact of use of Spanish in…

The purpose of this dissertation is to contextualize the measurement of the HLE for Spanish-speaking Latino families. This goal will be accomplished by using a series of HLE items to characterize the potential heterogeneity in the HLE of Spanish-speaking families as well as to examine differences in the HLE based on caregiver's language…

Purpose: The purpose of this study was to evaluate the efficacy of the EMBRACE Spanish support intervention for at-risk dual language learners and to determine which verbal and nonverbal characteristics of students were related to benefit from the intervention. The first study examined oral language and reading characteristics and the second study…

Second language (L2) learners of tone languages do not perceive and produce the different tones of the target language with equal ease. The most common explanation for these asymmetries is that acoustically salient tones are the easiest to learn. An alternative explanation is that tones are easiest to learn when they are highly frequent in the…

Adult second language (L2) learners often experience difficulty producing and perceiving non-native phonological contrasts. Even highly proficient bilinguals, who have been exposed to an L2 for long periods of time, struggle with difficult contrasts, such as /r/-/l/ for Japanese learners of English. To account for the relative ease or difficulty…
