Appropriateness-based models of language learning and teaching are rooted in a pervasive neocolonial agenda informed by Eurocentric epistemologies of "standard" or "academic" language (Flores & Rosa, 2015). In examining the normalized limitations of a language program through a raciolinguistic lens, we can better comprehend…

Foreign language learning is generally not required in the United States, despite its link to various cognitive and social benefits later in life. Students who speak a home language different from the instructional language of school may experience unique benefits when learning additional languages in school. The present study examined whether…

From a sociocultural perspective to assessment, this study investigated parents' beliefs about formative assessment. When North Carolina (NC) received an Early Learning Challenge Grant, its Department of Public Instruction was funded to develop a kindergarten entry assessment. The department proposed the development of a kindergarten to third…

With thousands of students enrolled in bilingual schools in Latin America, there are long-standing concerns regarding students' negotiation of their national identities. Arguments have been raised that these programs may contribute to the denationalization of students' identities, or that schools' prioritizing of foreign cultures results in…

Some evidence suggests that the home numeracy environment (HNE) is related to children's numeracy. Socioeconomic status (SES) and language minority status can also influence children's HNE and numeracy. Limited HNE research focuses on dual language learners (DLLs). Using a sample of preschool-aged children (n = 98) from low socioeconomic status…

How multilinguals reflect on and interpret their experiences abroad as they acquire an additional language has been undertheorized in study abroad research. Multilinguals navigate multiple identities, cross linguistic and social boundaries, and employ an array of resources to make meaning--that is, they engage in translingual practice. This…

The question of cognition in second language (L2) acquisition later in life is of importance inasmuch as L2 learning is largely mediated by domain-general cognitive capacities. While a number of these capacities have been shown to decline with age, individual differences in cognition increase over the lifespan. This microdevelopment study…

The present dissertation analyzed speech production and perception in early heritage Spanish-English bilingual children. Specifically, I investigated how perception and production of lexical stress develops in bilingual children. Current models of second language (L2) speech perception do not include heritage bilinguals or suprasegmental aspects…

This study analyzed eTandem video-conferencing exchanges between five pairs of university students of English as a foreign language (EFL) and Spanish as a foreign language (SFL). The exchanges, which involved discussion of seven tasks, took place on a weekly basis. Drawing on an interactionist perspective (Ellis et al., 2001a; Loewen, 2005), the…

Cognitive flexibility (switching) and control (inhibition) are among widely accepted cognitive advantages of bilingualism. Switch Cost (SC), i.e., the time difference to complete a switch versus non-switch task, is a construct for measuring the switching ability. The need to control the interference and switching between one's languages leads to…

This dissertation investigates Voice Onset Time (VOT), which serves as an essential property for differentiating plosive consonants in L1 and L2 Mandarin Chinese. It surveys VOT variations and demonstrates that they are affected by several phonetic and phonological properties, e.g., lexical tone, place of articulation (POA), speech rate,…

Children who speak one language at home and a different language at school may be at higher risk of falling behind in their academic achievement when schooling is disrupted. The present study examined the effects of COVID-19-related school disruptions on English language and literacy development among monolingual and bilingual children in the US.…

In this study, I examined how 34 Spanish-speaking English language learners (ELLs) used their linguistic resources (English and Spanish) and language modes (oral and written language) to demonstrate their knowledge of proportional reasoning in a dual language mathematics assessment task. The assessment allows students to see the item in both…

Although contexts of learning abroad have traditionally been conceived as optimal settings for language and intercultural learning, Researchers advocate the implementation of pedagogical interventions that promote qualitative intercultural dialogue and guidance in language and intercultural learning process. Yet, studies are needed that carefully…

Purpose: Few caregiver-implemented naturalistic language interventions (NLIs) are available for Spanish-speaking Latinos who have young children under 3 years with language delays, and there is a scarcity of studies that provide information about intervention development or social validity of interventions for this group. This study introduces…
