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.…

The present study examined the production of inalienable possession with body parts in Spanish among 20 school-age children of Mexican-born parents born and raised in the United States. The results were compared to those of 20 first-generation immigrant parents (main input providers), 27 Spanish-dominant children of similar age, and 12 Spanish…

The impact of attitudes on the learning process and on the academic results achieved by students has been the object of numerous studies, which have shown a connection between attitudes and learning. Similarly, the impact of students' attitudes towards learning a foreign language (mainly English) has been explored from a wide range of…

The use of English in advertising across non-English-speaking countries is pervasive, often seen as a strategy to evoke prestige, modernity, and global appeal. However, its effectiveness may depend on factors such as text length, linguistic complexity, and local language use, which remain underexplored. This study investigates how Spanish and…

This paper examines the acquisition of demonstratives (e.g., "that," "there") from a cross-linguistic perspective. Although demonstratives are often said to play a crucial role in L1 acquisition, there is little systematic research on this topic. Using extensive corpus data of spontaneous child speech, the paper investigates…

Even though engineering and science are tasked with developing solutions and knowledge for a diverse population, Black and Brown communities remain severely underrepresented in these disciplines. The problem exceeds easy solutions like "a seat at the table" and requires rethinking with whom and for whom the field designs ideas and…

The recent theoretical debate over the role of translanguaging in dual language programs can be described as moving from prohibition to promotion. Indeed, many researchers, theorists, and educators are now encouraging translanguaging. At the center of the debate are teachers and their beliefs, which some argue influence their practice. Teachers'…

One of the most intriguing questions in the investigation of second-language acquisition concerns the role of learners' first language (L1). Comparing learners of different backgrounds (L1 German vs. L1 Romance languages), we aim to explore the acquisition of tense and aspect features in Spanish as a second language (L2). Findings show that the L1…

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.…

The aim of this article is to explore how the teaching of English as a foreign language is planned in three plurilingual state schools in Catalonia. We carried out classroom observations (first and second grade of primary education) and interviewed the English teachers who teach these lessons and the headmasters of the three schools. The use of…

Informed by the stories of transnational youth's participation in massive multiplayer online role-playing games (MMORPGs) in Mexico, this study explores the language/identity development and successful (re)integration of these youth in Mexican schools and communities. Drawing on students' voices, we utilize a multimodal systemic functional…

In a present-day global world, immigrant communities manage multiple cultural and linguistic contexts. To better understand these cross-cultural connections, and bridge the fields of linguistics and transnationalism, the present study analyzes the interconnection between language use and symbolic transnationalism among heritage speakers of…

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…

Purpose: We investigated whether rhythm discrimination is mainly driven by the native language of the listener or by the fundamental design of the human auditory system and universal cognitive mechanisms shared by all people irrespective of rhythmic patterns in their native language. Method: In multiple experiments, we asked participants to listen…

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…
