Background and Objectives: In multicultural classroom settings, verbal interaction is not merely a process of transmitting information, but a social practice that reveals the interconnection of language, culture, and power. Learners from varied cultural backgrounds enter the classroom with distinctive norms of speaking, turn-taking patterns, politeness strategies, and interactional expectations rooted in their sociocultural values. At the same time, lecturers occupy positions of institutional authority that allow them to initiate topics, allocate speaking turns, evaluate responses, and legitimize particular forms of knowledge. Guided by an anthropolinguistic framework, this study views language as embedded in cultural meanings and social relations rather than as a pedagogical tool. Therefore, the study aims to examine lecturer–student verbal interaction by analyzing how cultural differences influence participation patterns and how classroom language operates as both an instructional medium and an ideological mechanism that shapes students’ academic identities. Methodology: The study employed a qualitative design using discourse ethnography. Data were gathered over one semester through classroom observation, audio-video recordings of interactions, and interviews with 30 students in the Indonesian Language Education program at a state university. Field notes and transcripts were thematically analyzed with a focus on turn-taking, topic control, register, and code-switching. Triangulation of observation, recording, and interview data ensured validity and reliability. Main Results: The analysis reveals that verbal interaction in multicultural classrooms tends to be asymmetrical. Lecturers dominate classroom discourse by controlling the distribution of speaking turns, determining topics of discussion, and acting as the primary arbiter of truth. Students’ responses are uneven and strongly influenced by their cultural backgrounds. Those from expressive cultural traditions actively participate, ask questions, and challenge ideas, while students from cultures that emphasize politeness and deference prefer to remain silent or provide brief, minimal responses. The lecturers’ language choices, particularly the use of formal registers, assertive intonation, and strategic code-mixing convey authority and reinforce hierarchical power relations. However, code-switching between Indonesian and local languages can create inclusion for students who share the same background but may simultaneously exclude those from different linguistic communities. Discussion: These findings demonstrate that classroom discourse is not a neutral space, but one shaped by the interplay of cultural norms, institutional hierarchies, and linguistic practices. The asymmetrical interaction patterns illustrate how lecturers’ speech acts as a mechanism of control, legitimizing certain voices while marginalizing others. Students’ silence should not be interpreted simply as passivity but rather as a culturally informed communication strategy rooted in respect, politeness, or avoidance of confrontation. The study underscores the importance of viewing language as both a pedagogical instrument that facilitates learning and an ideological tool that shapes students’ sense of belonging, linguistic security, and participation in academic life. Conclusions: The study concludes that verbal interaction in multicultural classrooms reflects cultural diversity and power relations. Lecturers’ language use not only delivers knowledge but also shapes identities and roles in academic contexts. To create equitable learning environments, educators should adopt culturally responsive strategies, promote inclusive participation, and reflect critically on power in discourse. © 2026, Suranaree University of Technology.
