Teacher-Student Communication in the Implementation of Merdeka Curriculum: A Case Study at SMK Krian 1 Sidoarjo

The primary problem addressed in this study is the suboptimal bidirectional interaction in the learning process, characterized by students' low willingness to express opinions and limited comprehension of learning materials. This study utilizes DeVito's interpersonal communication theory, employing five indicators : message clarity, feedback, empathy, openness, and communication equality. The methodology adopted is a qualitative approach with a case study design, employing data collection through interviews, observations, and documentation. The findings indicate that teachers' interpersonal communication tends to be open, empathetic, and interactive, although challenges persist in fostering fully dialogical communication. Effective interpersonal communication is proven to be a foundational element for the successful implementation of the Merdeka Curriculum in vocational education institutions.
