This study was part of a larger three-year investigation of the effectiveness of a small-group, content-focused (science, social studies) preschool shared book reading vocabulary intervention implemented with Spanish-speaking emergent bilinguals enrolled in a one-way dual-language bilingual program. A subset of bilingual preschool teachers (N =…

This paper explores how a transnational emergent multilingual (TEM) student established himself in relation to his teacher and peers in a culturally and linguistically diverse, sheltered English Instruction classroom. Specifically, it documents how the student initiated translingual and cross-cultural social interactions positioning himself as a…

Infants and toddlers experience the world in interaction with others. Likewise, social interactions are important in learning about math--concepts of number ("one," "two," "three"), space ("on top," "upside-down," "round"), and magnitude ("more," "big,"…

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…

In 2006-2007, California revised its English language proficiency (ELP) assessment, the California English Language Development Test (CELDT), which resulted in more stringent criteria and higher cut scores for meeting proficiency. Using regression discontinuity designs and a difference-in-differences approach, this study examines the effects of…

Using a randomized control trial, we evaluated the impact of a year-long professional learning (PL) program for teachers designed to support their multilingual learners' language and literacy skills. The PL included evidence-based instructional practices for literacy, a semi-structured model for collaboration, and a strengths-based approach in…

The Latino community has been disproportionately impacted by the COVID-19 pandemic, resulting in unique challenges. This paper explores the lived experiences of five Spanish-speaking Latina mothers of young children receiving early childhood special education (ECSE) services during the pandemic. Through in-depth qualitative interviews, this paper…

As gentrifying dual language (DL) schools in the United States increasingly attract students with linguistic, racial, and socioeconomic privilege, a key consideration is whether these schools are intentionally supporting the specific needs and assets of emergent bilingual (EB) students from Latinx families. This dissertation of practice examined…

Drawing on research interviews conducted as part of a larger study of bilingualism, we investigated how mid-aged Latin@ migrants--a group that has received little empirical attention in applied linguistics--interpret their ongoing cultivation of their own Spanish-English bilingualism at this stage of their personal and professional lives. We…

Heritage language speakers, those who have or claim a connection with the language of their ancestors, have become a group of interest in the United States, especially since programs to serve this population were initiated four decades ago thanks to the advocacy of grassroots organizations. Still, the reach of those programs is minimal and the…

This qualitative phenomenological research study was used to interview bilingual teachers on their perception regarding the referral process for Spanish-speaking students in emergent bilingual programs. Creswell's (2009) six-step method for analyzing phenomenological studies was used to analyze the interviews. The study results support that…

Bilingual and monolingual infants differ in how they process linguistic aspects of the speech signal. But do they also differ in how they process non-linguistic aspects of speech, such as who is talking? Here, we addressed this question by testing Canadian monolingual and bilingual 9-month-olds on their ability to learn to identify native…

Purpose: The aim of this study was to compare Basque and Catalan bilinguals' performance on the letter verbal fluency test and determine whether significant differences are present depending on the letters used and the language of administration. Method: The sample consisted of 87 Spanish monolinguals, 139 Basque bilinguals, and 130 Catalan…

Texas requires school districts to provide specialized linguistic programs (Texas Education Code, Chapter 29, Subchapter B 29.051) to meet the needs of students who are English learners (EL). These programs are intended to facilitate ELs' integration into the regular school curriculum and ensure access to equal educational opportunities. The…

The primary goal of this dissertation is to contribute to a predictive model of Spanish heritage grammars by applying recent advancements in machine learning to ferret out factors and covariates that give rise to the Spanish subjunctive. Given that "[p]redictive models would entail that we have a far better understanding of the various…
