Ideologies of teachers and students towards meso-level English-medium instruction policy and translanguaging in the STEM classroom at a Malaysian university

English medium instruction (EMI) as a language policy in higher education is based on monolingual conceptions and limits the use of the full linguistic repertoire of bilinguals/multilinguals in the university classroom. Informed by the constructs of language ideology (Spolsky, Bernard. 2009. Language management. Cambridge, UK: Cambridge University Press), translanguaging (Li, Wei. 2018. Translanguaging as a practical theory of language. Applied Linguistics 39(1). 9-30) and pedagogical translanguaging (Creese, Angela & Adrian Blackledge. 2010. Translanguaging in the bilingual classroom: A pedagogy for learning and teaching? The Modern Language Journal 94(1). 103-115), this case study aimed to examine the ideologies held by micro-level stakeholders (i.e., teachers and students) towards institutional English-only EMI policy, translanguaging, and the significance and scope of pedagogical translanguaging in EMI classrooms. Semi-structured interviews were conducted with six teachers and 10 students at a public research university in Malaysia. Also collected were a variety of publicly accessible institutional documents, including the focal university's programme brochures, promotional materials and policy statements on its website. Analyses of the interviews and documents revealed that although EMI was officially adopted in the programmes, both teachers and students advocated for translanguaging and underscored its important role in the transmission of new information, effective communication, and scientific meaning-making. In light of these findings, the study concludes that an inclusive language policy is required that allows teachers and students to access all their linguistic resources.
