This study details the development of a local test designed to place university Spanish students (n = 719) into one of the four different course levels and to distinguish between traditional L2 learners and early bilinguals on the basis of their linguistic knowledge, regardless of the variety of Spanish they were exposed to. Early bilinguals…

The rising demand for dual-language immersion (DLI) programs, which offer core instruction in two languages from early grades onward, has raised questions about program design and access. We leverage the rapid expansion of DLI schools across the U.S. state of Utah to estimate effects of DLI program availability on the academic achievement of…

Purpose: This longitudinal study investigated the trajectory of Spanish article accuracy in Spanish-English dual language learners (DLLs) from preschool to first grade, addressing the need for longitudinal data on the variability of Spanish grammatical skills in DLLs in English immersion classrooms. Method: Language sample analysis was conducted…

This dissertation focused on comparing the academic achievement and language proficiency in both English and Spanish of students at risk for language and learning difficulties, with bilingual typically developing students in two bilingual educational contexts: English as a Second Language program and Spanish two-way immersion program. Data was…

Multilingualism is often associated with advantages for acquiring additional languages. Theoretical approaches explain these advantages by assuming a Common Underlying Proficiency or a Metalinguistic Awareness. At the State Europe School in Berlin, students from different language backgrounds receive instruction in German and a partner language…

The two-way immersion dual language education program design includes the use of language labels to identify students as either the English speaker or the speaker of a language other than English. This paper examines four focal student and two teacher interviews to consider the ways in which the idea of a 'language expert' transpired during…

The rapid growth of Mandarin Chinese and English dual-language (DL) programs and the differences between these two languages have fostered the need to investigate the early literacy performance of young students in a Mandarin/English DL program. This study used the interactive transfer framework (Chung et al., 2019) to understand the Mandarin and…

Purpose: This study aims to document the impact of an 80-h virtual Spanish language immersion program on four elementary school leaders in Kentucky. Design/methodology/approach: This study used a mixed methods approach. Each subject participated in three semi-structured interviews with the researcher and a standardized oral language assessment.…

The purpose of this study was to create and prototype a dual language assessment task that allows young English learners to use their entire cadre of linguistic resources (language and non-verbal resources) to obtain information about their emergent language abilities. We developed a dual language assessment task in which students described a…

This study reports on a small-scale, longitudinal investigation on L2 Spanish oral development by English-home language (EHL) learners in an English/Spanish Two-Way Immersion (TWI) program in rural, eastern United States. It examined EHL learners' oral ability in L2 Spanish based on longitudinal assessment data from Kindergarten, Grade 2, and…

This report documents how native English speaking students enrolled in the two-way dual language program at Austin Independent School District (AISD) performed on STAMP 4Se, a Spanish-language proficiency test during the 2016-2017 school year.

Research on form focused instruction has provided support for the use of collaborative tasks in which learners focus their attention on formal aspects of language and consciously reflect on their own language use (i.e. produce language-related episodes or LREs). A strand of research on LREs in different educational contexts examines the effect of…

The assessment of dual language immersion (DLI) students' proficiency in the partner language plays a key role in program evaluation. This article reports findings from a large-scale study, drawing on cross-sectional assessment data from 73 schools and longitudinal data from 25 schools. Students were tested in the interpretive (listening and…

This study investigates second language acquisition of learners enrolled in a dual language/two-way bilingual immersion program. Two groups of third-grade students participated in this study. The first group was composed of Spanish-dominant participants learning English, and the second group was composed of English-dominant students learning…

We describe research results and lessons learned from a laboratory/ classroom collaboration with a school system offering both traditional English-only education and a dual-language track (Spanish/English). Through this collaboration, we addressed basic research questions informing malleable factors that impact cognitive development. In a…
