Lecturers' Interpersonal Communication Skills and Their Influence on Student Engagement in EFL Speaking Classes

This study examines the role of lecturers' interpersonal communication skills in enhancing English as a Foreign Language (EFL) speaking classes, focusing on both verbal and nonverbal communication strategies. Using a qualitative approach, data were collected through semi-structured interviews and classroom observations involving two EFL lecturers in Indonesia. The findings reveal that lecturers’ deliberate application of interpersonal communication, including verbal techniques such as modeling English use and engaging discussions, as well as nonverbal cues like gestures and body language, positively impacts students’ motivation, confidence, and active participation in speaking activities. Lecturers highlighted the importance of building rapport and creating a supportive classroom environment to foster student engagement, aligned with Vygotsky's Social Constructivist Theory on interactive learning. However, challenges related to cultural variations in nonverbal communication were noted, indicating a need for intercultural awareness in diverse classrooms. This study contributes to EFL pedagogy by emphasizing the significance of interpersonal communication in promoting effective language learning and suggests incorporating communication skills training into EFL teacher development programs.
