When deciding what constitutes students' "on task" or "off task" mathematical communication, teachers and researchers are also making judgements about what is, and what is not, mathematics. In this paper, we question our ability to separate the mathematical from the nonmathematical. We explore intersecting storylines in Grade…

In this study, we present an educational board game designed to promote both mathematics and Chinese language learning. We use text-mining techniques to analyze dialog by 40 students, in six groups playing a board game in a dual language immersion context. Our findings provide evidence to support past claims and arguments that play and…

Bilingual education in the United States basically involves English language learners (ELLs) in mainstream classes and students who are learning an additional language in a foreign language immersion (FLI) program. Although academic vocabulary instruction for ELLs has attracted increasing attention in the past two decades (e.g., McQuillan, 2019;…

Research focused on learning mathematics in a 2nd language is generally located in individual 2nd-language contexts. In this ethnographic study, I investigated mathematics learning in 4 different second-language contexts: a mainstream classroom, a sheltered classroom for Indigenous students, a welcome class for new immigrants, and a…

Researchers have argued for an orientation to language as a resource that values bilingualism in mathematics classrooms. However, little is known about what mathematics teachers can do to translate a language-as-resource orientation into productive classroom practice. In this study, I analyze video data from two language immersion classrooms to…

Teachers in mathematics classrooms where the language of instruction differs from students' first language face competing demands regarding mathematics and language teaching. In this study, I conducted an analysis of genre of teaching episodes to examine how a teacher in a Spanish immersion third-grade classroom in the US responded to those…

This research describes language use by four first-grade students during mathematics and Language Arts instruction in a one-way 50/50 Mandarin immersion classroom. The urban public school was situated in the heart of an African-American community in the Pacific Northwest region of the United States. Participants were video- and audio-recorded…

Prior research has shown that EL classification is consequential for students, however, less is known about how EL classification impacts students' outcomes. In this study, we examine one hypothesized mechanism: teacher perceptions. Using nationally-representative data (ECLS-K:2011), we use coarsened exact matching to estimate the effect of EL…

Most studies of intercultural competence in bilingual programs have been conducted in non-Asian contexts resulting in little information on how Indonesian educators promote intercultural values within bilingual programs. This research contributes to the body of literature that examines the promotion of intercultural values within bilingual higher…

Two-Way Immersion (TWI) programs have demonstrated positive outcomes in students' academic achievement in English, yet less is known about content teaching and learning in the non-English language in these programs. This study uses math instruction as a lens to identify pedagogical strategies and challenges in the teaching of math in Korean to…

This book uncovers the important issues in language learning and teaching in the intelligent, digital era. "Social connectivity" is a contemporary style of learning and living. By engaging in the connectivity of physical and digital worlds, how essential parts of language learning and teaching can be achieved? How can the advanced…

In 2007, Arizona voters passed House Bill (HB) 2064, a law that fundamentally restructured the Structured English Immersion (SEI) program, putting into place a 4-hour English language development (ELD) block for educating English language learners (ELLs). Under this new language policy, ELL students are segregated from their English-speaking peers…

There are a number of studies on teachers' corrective feedback and students' uptakes in immersion settings, but the majority is carried out in the North American context. Based on limited data, "the counter­-balance hypothesis" was proposed by Lyster and Mori (2006) to explain distributions of teacher feedback and students' uptakes in…

Standardized tests have been selected as a key assessment factor in expanding the academic achievement of the national student population. However, these tests position immigrant students at the risk of academic failure, leading education experts to search for new strategies and teaching models. The "Handbook of Research on Assessment…

This article serves as the introduction to this special issue of "Language Teaching Research" on content-based language teaching (CBLT). The article first provides an illustrative overview of the myriad contexts in which CBLT has been implemented and then homes in on the five studies comprising the special issue, each conducted in a…
