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…

Language ideologies can powerfully shape language learner perceptions and progress. This qualitative study investigated and reports findings based on analysis of interviews with 14 participants who self-identify as advanced users of Spanish. While dominant language ideologies in the U.S. often undermine learners reaching high levels of language…

This dissertation delves into second language acquisition, sociophonetic variation, and speech perception, investigating how prior linguistic experiences and exposure to regional variations in a second language influence the decoding of dialectal linguistic cues. It aims to enhance the understanding of words pronounced with different phones and…

This dissertation examines heritage language learners of Spanish enrolled in university Spanish courses, focusing on their strategic use of suprasegmental speech features in two speaking tasks. The research investigates attitudes' influence on heritage language learners' speech production in different task types. Participants engaged in two…

This project explores how the variation in language experiences and attitudes that Mexican American Spanish heritage speaker bilinguals in the United States have affects their speech perception in both their languages. Heritage language bilinguals speak as a first language a minority language that they have cultural ties to (e.g., Spanish in the…

This investigation examined the effectiveness of different types of explicit classroom instruction on second language (L2) development of the Spanish discourse marker (DM) "pues." While several studies have addressed the positive effect of explicit instruction on L2 DM development, the current investigation moves beyond the…

The present study examined the acquisition of Spanish grammatical gender in 22 bilingual children (aged 5;0 to 13;5 years; Med=9;4 years; STD=2.3) who were born and raised in the United States and acquired Spanish as heritage speakers--that is, they learned Spanish, the minority language, in a home setting (Valdes, 2001). Each of the child…

This qualitative study explores the roles that undergraduate Spanish as a second language (L2) learners ascribe to their identities, backgrounds, sociocultural contexts, and imaginations in the development of their ideal second language (L2) selves (Dornyei 2009), rooted L2 selves (MacIntyre et al., 2017) and investment (Darvin & Norton, 2015;…

This research investigated how a Critical Sociocultural Linguistics Literacy (CriSoLL) approach to authentic materials supports student literacy in a mixed Spanish heritage language (SHL) and additional language (L2) Spanish intermediate course at the university level. Using a qualitative approach (Cho, 2018; Esposito & Evans-Winters, 2021)…

This dissertation deals with the perception of the aspirated coda /s/ by Spanish L2 learners. Second language research, with some exceptions, focuses on whether L1English-L2 Spanish learners can perceive the aspirated variant, showing that only advanced learners with time spent in s-weakening regions succeed at the task. L2 studies about…

Automated corrective feedback (ACF), in which a computer system helps language learners identify and correct errors in their writing or speech, is considered an important tool for language instruction by many researchers. Such systems allow learners to correct their own mistakes, thereby reducing teacher workload and potentially preventing issues…

This study examines the effectiveness of study abroad and pragmatic instruction on L2 learners' acquisition of the speech acts of requesting, thanking, and refusing. In the study, speech acts produced by L2 learners of Spanish who studied abroad for six weeks in Buenos Aires, Argentina and L2 learners who received eight weeks of pragmatic…

With a recent interest in virtual reality, educators have begun to explore how using technology can mitigate feelings of Foreign Language Anxiety, or FLA. For this dissertation, the author has co-created a virtual reality conversation scenario to test with novice and intermediate-level Spanish students at the University of Wyoming. The research…

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…

Research into second language acquisition (SLA) has shown that individual difference (ID) variables can be strong predictors of language achievement (e.g., Dornyei, 2003; Skehan, 2003). Traditionally, this research conceptualized ID variables as static and monolithic variables (e.g., Dornyei, 2010). More recently scholars have questioned this…
