This brief report summarizes the development and psychometric properties of German reading fluency passages as compared to English reading fluency passages for immersion language learners. Results indicated that scores from German language reading fluency passages alone were (a) somewhat less reliable than scores from English publisher-developed…

This causal-comparative quantitative study investigated the effects of dual-language immersion programs on reading and math achievement for non-English learner (EL) students that qualify for free/or reduced lunch status. The purpose of the study was to explore if dual-language programs are effective for non-EL students that qualify for free/or…

Seven cohorts of students (N = 258) who completed a K-5 Spanish Immersion (SI) program in a suburban California school district were followed longitudinally through middle and high school to understand their academic, language, and social emotional outcomes. Academic and language outcomes included Spanish classes and grades, standardized Math and…

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…

This dissertation explores the potential differences in Armenian parental attitudes of those whose children were enrolled in a Dual Language Immersion Program (DLIP) and those whose children who were not enrolled in a DLIP towards four constructs of school perceptions: cultural appreciation (CA), academic progress (AP), importance of learning a…

This paper examines the construct of bilingual phonemic awareness in Irish-English bilinguals. Though traditionally viewed as a skill or ability which transfers across languages, recent accounts have considered whether phonemic awareness has a language-specific component. This study used a cross-sectional design to examine this question. A total…

The vision for the Leadership Richland One MSAP project was that all students will have the opportunity to succeed academically through a high-quality education in an environment characterized by diverse social, economic, ethnic, and racial backgrounds. To improve student achievement, major project goals and objectives focus on four areas:…

The purpose of this quantitative causal-comparative study was to raise awareness of the effects of soft school closures on student reading fluency in traditional, Science, Technology, Engineering, and Mathematics (STEM)-related, or Dual Language Immersion (DLI) schools. There is little research on which type of school, whether traditional,…

In this study, we propose a hypothesis that domain-general auditory processing, a perceptual anchor of L1 acquisition, can serve as the foundation of successful post-pubertal L2 learning. This hypothesis was tested with 139 post-pubertal L2 immersion learners by linking individual differences in auditory discrimination across multiple acoustic…

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…

This research uses a descriptive quantitative statistical design to examine campus-level results from the State of Texas Assessments of Academic Readiness (STAAR). The focus is on describing the achievement disparities between campuses that implemented Transitional Bilingual Education (TBE) programs and those implementing Dual Language (DL)…

This exploratory study evaluated the impact of a Spanish second language (L2) domestic immersion (DI) program that was developed expediently at a large university in the United States in response to widespread study abroad (SA) program closures due to COVID-19. Spanish language learners (n = 14) participated in an intensive, six-week summer…

Artificial Intelligence (AI) and Extended Reality (XR) have been employed in several foreign language education applications to increase the availability of experiential learning methods akin to international immersion programs. However, research in multi-modal spoken dialogue in L2 combined with immersive technologies and collaborative learning…

Using the 2.4-million-word written Spanish subsection of the Corpus of Utah Dual Language Immersion, collected from a large-scale standardized writing assessment of K-12 Spanish second language (L2) students, this study focuses on lexical complexity as operationalized by three measures: lexical diversity, lexical density, and lexical…

Language immersion education uses a non-English language for a significant portion of instruction. One goal is to develop bilingual students, which many argue provides cognitive benefits. Using data from school choice lotteries, I estimate the effect of random assignment to a language immersion school on achievement in math and reading. Winning…
