The purpose of this study is to investigate how speaking classes at an Islamic university implement culturally responsive teaching (CRT). More specifically, the research is about three lecturers who teach speaking courses at Universitas Muslim Indonesia (UMI), a university in South Sulawesi with a multicultural student body. The main purpose is to analyze how lecturers ensure their classes are inclusive and value diversity. In-depth interviews were used to collect data using a qualitative and exploratory design. The research found that the lecturers approach teaching by including cultural languages, applying special learning methods, connecting with students’ feelings, and encouraging group learning. They also reflect these values in the way they respond and develop teaching materials. According to the study, lecturers must incorporate cultural understanding and respond well to diversity in educational spaces. Results highlight that it would be helpful to provide language educators with training in culturally responsive teaching, especially in teaching speaking.
