English-medium instruction and intercultural competence in Brazil: insights from a public university

Purpose This study examines how lecturers in a Brazilian public university perceive English-medium instruction (EMI) and the development of intercultural competence (IC) within their teaching. It aims to understand the importance they assign to IC, the challenges they encounter and the types of institutional support they consider necessary for integrating IC into EMI. Design/methodology/approach This study draws on data from an online questionnaire completed by 31 lecturers across multiple disciplinary fields. Closed-ended items generated descriptive statistics on language use and proficiency, while open-ended responses underwent qualitative content analysis, combining deductive and inductive coding procedures. The instrument was part of a larger project that collected comparable data in Brazil and Portugal. Findings EMI use was selective and concentrated in course materials, readings and slides rather than full English-medium course delivery. Lecturers identified insufficient English proficiency, lack of training, limited institutional policies and restricted opportunities for intercultural exposure as major barriers. They viewed IC as a multidimensional competence encompassing educational, social and professional dimensions. Participants emphasized the need for continuous pedagogical training, sustained language support and institutional recognition of EMI- and IC-related work. Practical implications Findings highlight the urgency of coordinated institutional policies, integrated EMI–IC professional development, expanded language support and opportunities for intercultural engagement to sustain EMI initiatives in Brazilian higher education. Originality/value This study provides one of the few empirical examinations of how Brazilian lecturers conceptualize IC within EMI practice. It offers context-specific insights into how structural inequalities and limited institutional frameworks shape EMI adoption in public, tuition-free systems.
