This study investigated whether second language (L2) classroom instruction that incorporates a principled approach into the use of the first language (L1) by students and instructors has an effect on beginning learners' development of L2 speaking and writing proficiency, compared to L2-only instruction, over the course of one semester.…

While formal L3 morphosyntactic acquisition research has focused on the roles of the L1 versus L2 during the L3 initial stages, we examine their roles during development. Specifically, we explore whether the L3 (here, Portuguese) revision process after non-facilitative transfer differs whether the initial L3 representation reflects the L1 or L2.…

Language learning and the development of language proficiency are central concerns in the study of immigrant adaptation. This paper analyzes the social construction of language proficiency among Indigenous Guatemalan Maya youth in the United States--specifically, undocumented young adults who migrated to Los Angeles, California as unaccompanied…

This dissertation presents findings from an ethnographic exploration of the role of language in the academic experiences of Chicanx and Latinx university students at an emerging Hispanic Serving Institution. Specifically, this dissertation presents an extensive analysis of the language ideologies encountered, enacted, and described by…

The purpose of this research was to identify the role of the level of proficiency in the English language with high-performing third-year students in the Mayan area of Yucatán, near a tourist region called the Riviera Maya. The aim was also to explore the relationship between learning a second language and the subsequent overall improvement in the…

Even though the majority of Colombian professors are also involved in research, they have limitations in their English language skills that separate them from the rest of the scientific society. Evidently, these limitations have become an obstacle in the awareness of professors' modest, but no less important, research work. In order to carry out…

With English-medium instruction (EMI) gaining momentum in higher education across the globe, teacher education programmes (TEPs) are being redesigned to equip lecturers with the skills necessary to deal with increasingly international classrooms. While most of these TEPs mainly pursue improving lecturers' English language proficiency they rarely…

This paper describes the language policies at 38 institutions of higher education on the Caribbean island of Puerto Rico. As a commonwealth of the US, Spanish and English hold co-official status on Puerto Rico despite the fact that majority of islanders use Spanish as their first language. Given the colonial status of the island, English has held…

This paper aims to gain insight into (Spanish) tourists' multilingual experiences by analyzing spontaneously written online travel diaries. Using the conceptual framework of Rapport Management Theory (RMT; Spencer-Oatey 2008), I analyze reports on the tourists' mother tongue, local languages, and English as lingua franca in order to examine the…

We assessed the roles of first language (L1) and second language (L2) proficiency in the processing of preverbal clitics in L2 Spanish by considering the predictions of four processing theories--the Input Processing Theory, the Unified Competition Model, the Amalgamation Model, and the Associative-Cognitive CREED. We compared the performance of L1…

The effects of "transitional-bilingual" and "dual-language" educational models on proficiency in students' home language (Spanish) were examined in a study of English language learners in the first and second grades in a large urban elementary school. In each grade, students were taught with either a transitional-bilingual…

This study used ERP (event-related potentials) to examine both the role of the L1 and the role of individual differences in the processing of agreement violations. Theories of L2 acquisition differ with regard to whether or not native-like acquisition of L2 features is possible (Schwartz and Sprouse, 1994, 1996; Tsimpli and Mastropavlou, 2007),…

The general goal of this dissertation is to explore two decades-long second language (L2) acquisition issues: whether and to what extent the L2 learner's first language (L1) and Universal Grammar (UG) respectively play a role in L2 development. Targeting English verb phrase ellipsis (VPE) and "wh"-extraction out of VPE, four…

This three-year longitudinal study investigated the role of language of instruction in moderating the relationships between initial levels of English oral language proficiency and Spanish reading comprehension and growth in English reading comprehension. The study followed Spanish-speaking English language learners in English-only literacy…

While language aptitude has been investigated actively within second language research, there is a current dearth of research on the effects of aptitude in cases of attrition. The aim of the present investigation was to explore the role of language aptitude for L1 proficiency in speakers who experienced a break with their L1 setting prior to…
