Efektivitas Teknik Coaching Model Tirta Terhadap Supervisi Akademik Dan Peningkatan Kinerja Guru Serta Motivasi Student Agency (Studi Di MTSN 2 Kabupaten Tangerang Dan SMPN 3 Cisoka Kabupaten Tangerang Banten)

The national educational transformation demands a shift in supervisory paradigms from rigid administrative oversight toward professional empowerment focused on student ownership. This study aims to analyze the effectiveness of the TIRTA model coaching technique in academic supervision on enhancing teacher performance and student agency motivation at MTsN 2 Tangerang Regency and SMPN 3 Cisoka Tangerang Regency, Banten. A causal associative quantitative approach with a survey method was employed, involving 57 teachers and 92 students selected through purposive sampling and proportional random sampling techniques. Data were gathered using Likert-scale questionnaires that met validity and reliability standards, then analyzed using multiple linear regression via IBM SPSS version 27. The findings demonstrate that the TIRTA model coaching technique in academic supervision exerts a positive and significant influence on both teacher performance and student agency motivation, partially and simultaneously, with teacher performance serving as the most dominant predictor. This study concludes that strengthening reflective partnership supervision consistently elevates teachers' instructional performance, which directly reinforces students' learning leadership across Islamic and general secondary schools.
