Among inequities faced by multilingual learners, engagement in science education is one of the most persistent. Research suggests leveraging students' full multilingual repertoires in science education can help address this gap. However, pervasive monolingual norms in schooling may impede multilingual engagement, impacting students' multilingual…

This paper examines the chronotopic nature of physics discourse and instructional practices that are mediated through the integration of disciplinary spatial repertoires and mathematical symbolic systems. The paper addresses how meanings are constructed during instruction between bilingual international teaching assistants (ITAs) and undergraduate…

This paper presents an instructional model to incorporate English-language communication between international practicing scientists and English learners into secondary science lessons. The aim was to identify a method that lets pupils practice English as the language of science and that elicits positive affective attitudes in the form of…

The visual mode provides emergent bi/multilinguals an essential resource to construct scientific explanations. Yet, while a metalanguage is used to describe the written mode of scientific language such as, claim, evidence, reason; there is little research that makes students aware of the metalanguage of a visual mode. We propose an introduction to…

This case study examines how three science teachers in a secondary school attended to the language demands of science through oral interactions in classes of multilingual students with diverse English proficiencies. It specifically unpacks the intricate role of language in science education, where teachers must address disciplinary-specific…

Language in education for children and youth from low-income communities of color, including those learning English as an additional language, has been fraught for decades with ideological entanglements, conceptual ambiguities, and empirical limitations. Meanwhile, the teacher learning challenge to implement equitable teaching practices remains…

Science teachers mediate social and academic language in science classrooms through teacher talk and classroom discourse. In multilingual classrooms, ways home and international languages are deployed can affect conceptual learning of science. This study investigates, through Bakhtin's dialogic perspective, multilingual language practices and…

This study of three science teachers' lessons on heat and temperature seeks to characterise classroom talk that highlighted the ways language is used and to examine the nature of the language demands revealed in constructing, negotiating, arguing and communicating science ideas. The transcripts from the entire instructional units for these…

Drawing on recent conversation-analytic and socio-interactionist research on students' participation in L1 and L2 classroom interaction in teacher-fronted activities, this paper makes a step further by presenting an exploratory study of students' displays of willingness to participate (WTP) in classroom interaction and pedagogical activities…

This paper reports on research into a continuing professional development (CPD) project, "Projet de Renforcement de l'Enseignement des Mathématiques, des Sciences et de la Technologie" (PREMST) [Strengthening Mathematics, Science, and Technologies in Education Project]. The literature review reveals few examples of CPD changing the…

This paper reports on the classroom languaging practices of a group of science teachers in rural and township schools in South Africa where the majority of learners learn through the medium of English, despite the fact that it is the home language of only a small minority; and learners' poor English proficiency frequently restricts their access to…

Educators worldwide have been attracted by lesson study for its teaching and learning enhancement potential. However, some believe it takes for granted language, out of which all teaching and subject matter are made. Employing a functional linguistics lens in an analysis of two second language science lesson studies, called "learning"…

In view of the current debate in Malaysia about the teaching of science and mathematics in English, a qualitative study was undertaken involving a purposeful sampling of three non-physics teachers to ascertain how well equipped they were with the necessary pedagogical content knowledge relating to the teaching of the topic of "heat…

This paper examines whether students involved in CLIL are able to learn content through the medium of L2 and simultaneously exhibit significant gains in L2 vocabulary knowledge. Two experiments were set up in two public primary schools. Two groups of 6th grade students participated in each experiment. The first group was taught three 80-minute…

This case study is part of a larger project which aims to determine the usefulness and validity of a model of a pre-service content and language integrated learning (CLIL) teacher education programme inserted in a Master's degree, whose main pedagogical option is to achieve teacher empowerment through cycles of collaborative teaching and shared…
