Canadian students enrolled in either French-immersion or English-instruction programs were followed from Grades 2 to 3 (M[subscript age] = 7.8 years to 8.9 years; N = 244; 55% girls). In each grade, students completed two mathematical tasks that required oral language processing (i.e., word-problem solving and number transcoding from dictation)…

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…

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…

Effectively engaging students in mathematics discourse is challenging, especially in a language other than the one in which you learned mathematics. Teachers must manage the academic as well as social function of language. In Spanish-English bilingual classrooms in the U.S., changing the language of instruction to Spanish may not be enough to…

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 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…

Using a student's native language, either as a medium of instruction or as a scaffolding technique, has been used effectively in many classrooms throughout the U.S. In the past, many schools provided native language instruction to meet the needs of English Language Learners (ELLs). However, with the advent of antibilingual education proposals such…

A teacher's manual was developed for an elementary level mathematics course in Spanish as part of an immersion program for English speaking children. The Level A manual is designed for kindergarten and grade 1 pupils. Teaching procedures, conceptual objectives, vocabulary, and structures are included. Activities are designed to teach either…

A teacher's manual was developed for an elementary level mathematics course in French as part of an immersion program for English speaking children. The Level A manual is designed for kindergarten and grade 1 pupils. Teaching procedures, conceptual and language objectives, vocabulary, structures, and learning activities are included. Activities…

A teacher's manual was developed for an elementary level mathematics course in Spanish as part of an immersion program for English speaking children. The Level E manual is designed for grade 4 pupils. Teaching procedures, conceptual and language objectives, vocabulary, structures, and learning activities are included. Activities are designed to…

A teacher's manual was developed for an elementary level mathematics course in Spanish as part of an immersion program for English speaking children. The Level F manual is designed for grade 5 pupils. Teaching procedures, conceptual and language objectives, vocabulary, structures, and learning activities are included. Activities are designed to…

The purpose of the study was to assess the relative mathematics achievement of English-speaking pupils enrolled in grades 3, 6, and 9 in regular English or French immersion programs during the 1981-82 and 1982-83 school years. The data were obtained as part of a 2-year evaluation of a system-based mathematics program developed by an Ontario school…

The present paper questions the validity of Macnamara's (1966) finding that teaching arithmetic through a bilingual's weaker language leads to retardation in problem arithmetic. By comparing the performance of immersion pupils on an Irish (as a second language) version of the problem arithmetic test with the performance of non-immersion pupils on…
