Language Teaching Research

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 distinct instructional setting: two-way Spanish—English immersion in the USA, English-medium ‘nature and society’ lessons taught at a middle school in China, English-medium math and science classes in Malaysian high schools, English-medium history classes in high schools in Spain, and ‘sheltered instruction’ classes for English language learners in US schools. In spite of such divergent contexts, the five studies converge to underscore the pivotal role played by teachers in CBLT and the concomitant need for professional development to support them in meeting some of the challenges specific to CBLT.

This study examines the Spanish use of students and teachers at a US two-way immersion school. Students and teachers from Grades 1, 3, and 8 (5—6-year-olds, 7—8-years-olds, and 12—13-yearolds, respectively) were observed and interviewed, and students completed questionnaires to determine what factors influenced their language of choice and their divergence from Spanish when it was the language of instruction. Although students showed an overall preference for English, particularly in interactions with peers, findings indicate that students’ language background, culturally relevant teaching activities, teacher language use, and students’ sensitivity to others’ need for language accommodation influenced their use of Spanish with peers.

This article reports a study of aspects of pedagogy that can bring about students’ cognitive engagement with academic content and, thus, use of the academic language in content-based language lessons in three middle schools in Xi’an, China. Two criteria — academic content level and depth of processing — were used to determine cognitive content engagement by students. A detailed analysis of three lessons taught by the same teacher is presented in this article. These are selected to highlight the differences between teaching that facilitated engagement and the use of the academic language and teaching that failed to do so. The analysis shows that engagement seemed to occur when the teacher focused the content on challenging technical academic knowledge and helped students explore this content in depth. She focused on relationships between meanings rather than facts in isolation and demanded the processing of knowledge in different ways, which created the space for the use of academic language. She structured her lessons in a cyclical manner and exploited the feedback moves in the predominantly initiation— response—feedback (IRF) classroom interaction pattern to facilitate deep processing. She also had clear content and language learning objectives.

This article presents data from a study examining secondary mathematics teachers’ and science teachers’ implementation of a language of instruction policy in Malaysia, which made English the medium for mathematics and science instruction. It explores the beliefs of math, science and language teachers, and how these beliefs influence their pedagogical practices in content-based language instruction classrooms. The study uses a mixed-methods approach for data collection and data analysis. Data is analysed using perspectives from content-based language teaching (CBLT) and from research on mathematics and science instruction for English language learners (ELLs). The results indicate that teachers’ beliefs about their respective roles as only content teachers or only language teachers limit students’ language learning opportunities. Factors such as curricular requirements, exam pressure and time constraints also shape classroom interactions, and have implications for student learning as well. The findings reveal the lack of collaboration between content and language teachers, and the need for sustained professional development concerning content and language integration for both groups of teachers. This study extends work on content-based language teaching to the previously unexamined Malaysian context. Its findings contribute to the ongoing work of improving instructional practices in content-based classrooms to integrate and maximize content and language learning for English language learners.

This article presents a study of written development in English as a foreign language produced in a content and language integrated learning (CLIL) environment. The texts analysed, from history classes, were collected annually over the four-year obligatory junior secondary education program from the same students (aged 12 to 16), in two state schools in Madrid, Spain. The ability to produce coherent texts and the appropriate management of the nominal group, or noun phrase, to create disciplinary registers are key skills for academic writing. With the purpose of identifying the linguistic resources used to create coherence and appropriate register in the CLIL students’ written texts, all the nominal groups in the corpus were analysed in terms of recoverability of the elements they referred to, further classifying the referential elements into different types. Finally, the structure of the nominal groups was analysed for pre- and post-modification. The results show development in the control of textual resources, as well as some increase in nominal group complexity, over the four years. The study suggests that CLIL settings, which focus primarily on the learning of content, provide suitable contexts in which to develop written discourse, since the students can draw on a solid knowledge base from which to create their text. Students need to be given the opportunity to construct scaffolded but longer and more autonomous texts in the required genres, an ability which is inextricably linked to academic success in the content area.

This article describes an extended program of research in sheltered instruction and the effects on the academic literacy development of English language learners. It also highlights the challenges of scaling up an instructional intervention. The intervention was the Sheltered Instruction Observation Protocol (SIOP) Model, an approach that teaches subject area curriculum to students learning through a second language using techniques that make the content material accessible and also help develop the students’ second language skills. Three successive studies looked at teacher change over time and student achievement on standardized assessments and researcher-developed measures. Results of the three studies reveal that students with teachers who were trained in the SIOP Model of sheltered instruction and implemented it with fidelity performed significantly better on assessments of academic language and literacy than students with teachers who were not trained in the model. The article offers guidance for strengthening professional development for teachers so the quality of instruction they deliver to English language learners improves and the students strengthen their English language and academic outcomes.
