This study uses a qualitative approach, data were collected through interviews, observations, and documentation from students and teachers. The results showed that the integration of regional languages increased students' enthusiasm, made them more connected to the teaching materials, and expanded their vocabulary. Students found it easier to understand new vocabulary related to everyday life, while the use of regional languages also provided a rich cultural context.
