This paper draws from a broader research project and reports on literacy program supports and instructional strategies in two-way immersion (TWI) classrooms (Grades 3-5) where the partner language is Spanish. The study examined TWI classrooms in which students from multiple demographics were performing at or above the state average on reading…

This three-article dissertation examined how policy choices in three key policy areas -- initial enrollment, service provision, and reclassification -- impact English learner (EL)-classified students. The first article examined the national landscape of state statutes, regulations, and state education agencies' (SEA) guidance that support…

This article focuses on the reported experiences of three focal students who participated in a Spanish/English dual language program in their southern California school district throughout their elementary and middle school years.

Although English-Chinese bilingual development has been studied in community contexts, it has not been adequately addressed in the K-12 Chinese immersion classrooms despite the increasing number of Chinese immersion programs across the United States. To inform effective pedagogies in Chinese immersion classrooms, this study reports on a nine-month…

Two-way immersion (TWI) programs in the U.S. integrate learners with different home languages and varied proficiencies in Spanish and English. Although both English home language (EHL) and Spanish home language (SHL) TWI students succeed academically in English, they often experience incomplete acquisition (Montrul 2011. "Morphological Errors…

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.

This mixed-methods study investigates the ideologies, attitudes, and understandings of language, bilingualism, and second language acquisition among students, teachers, and parents in a Bay Area dual immersion (DI) program. The work shows that despite rhetoric and awareness of language variation, students' and teachers' approaches to language…

Two-way immersion (TWI) programs in the US are not reaching their minority language learning potential. While English home language (EHL) students develop functional proficiency, their minority language (e.g., Spanish) remains grammatically inaccurate. Spanish home language (SHL) students may also develop non-native-like aspects. Scholars suggest…

This study investigated the effect of mother tongue instruction and gender on second language acquisition using a causal-comparative quantitative research design. The two distinguishing groups compared were (i) learners that were taught in their mother tongue (Afrikaans) and (ii) learners that were not taught in their mother tongue but in English,…

This study compares the frequency and distribution of different types of corrective feedback (CF) (recasts, prompts and explicit correction) and learner uptake in 43 hours of classroom interaction at the 4th-5th grade level across three instructional settings: (1) two content and language integrated learning (CLIL) classrooms in Spain with English…

This study examined metalinguistic awareness in children who were becoming bilingual in an immersion education program. The purpose was to determine at what point in emerging bilingualism the previously reported metalinguistic advantages appear and what types of metalinguistic tasks reveal these developmental differences. Participants were 124…

Anglophone children in Grades 2 and 5 who attended an intensive French immersion program were examined for linguistic and metalinguistic ability in English and French.

This quantitative, causal-comparative study examined the possible cause and effect relationship between educational programming, specifically one-way Spanish immersion and traditional English-only, and native English-speaking fifth graders' vocabulary and reading comprehension. Archival data was used to examine students' reading achievement as…

Using a sociocultural theoretical lens, this study examines the nature of student interactions in a dual immersion school to analyze affordances for bilingual language learning, language exchange, and co-construction of language expertise. This article focuses on data from audio- and video-recorded interactions of fifth-grade students engaged in…
