Tirta Coaching Model for Teachers’ Socio-Emotional Competencies Development

The challenges of contemporary education in Indonesia present a compelling case for transforming traditional supervision approaches, particularly in addressing the socio-emotional dimensions of teacher competence. This qualitative case study explores the implementation of TIRTA (Tujuan, Identifikasi, Rencana Aksi, Tanggung Jawab= Objectives, Identification, Plan Action, Responsibility) coaching techniques in academic supervision to enhance teachers' personal and social competencies at SMA Negeri 5 Bengkulu Selatan. The study employed semi-structured interviews with 23 participants comprising three supervisors, 15 teachers, and five students, alongside participant observations and document analysis conducted over eight months. Data were analyzed using thematic analysis and the Miles-Huberman interactive model. Findings reveal a significant paradigmatic transformation from hierarchical control to collaborative empowerment. The result indicated a 63.5% average increase in teachers' personal and social competencies. The TIRTA model proved effective as a structured yet flexible framework, with collaboration and interpersonal communication demonstrating the highest improvements of 1.9 and 1.8 points respectively. The study demonstrates that coaching-based supervision creates sustainable learning ecosystems responsive to contextual needs, transforming organizational culture beyond individual teacher development. These findings contribute to academic supervision literature by providing evidence-based strategies for implementing culturally responsive coaching models in semi-urban educational contexts, addressing the critical gap between policy aspirations and implementation realities in Indonesian education.
