‘It becomes increasingly complex to deal with multiple channels’: materialised communicative competence and digital inequality in English-medium higher education in the digital era

This article explores university students' communicative competence for English-Medium Instruction (EMI) at a Swedish university in the era of digitalisation and blended learning. Based on a linguistic ethnography, we present an argument for communicative competence as repertoire assemblages orchestrating digital materiality and human language to construct meanings. The study shows how diverse digital multimodalities and AI-language tools are essential features of spatial repertoires for academic communication, and how they cooperate with and mediate students' personal repertoires to accomplish interactive learning tasks in EMI contexts. The study also highlights how digital diversity in EMI causes a 'digital divide', potentially impacting power relations among students. These findings underline the importance of acknowledging the communicative value of digital materiality and negotiating difference and normativity for intercultural academic communication in EMI.
