Abstract

Teacher professionalism plays an important role in improving the quality of learning in madrasah. One of the strategies to improve this professionalism is through academic supervision by the madrasah head. This study aims to describe the implementation of academic supervision by madrasah principals in improving teacher professionalism at MTsN 4 Karawang. This research uses a qualitative approach with a case study method. Data collection techniques were conducted through in-depth interviews, observation, and documentation. Informants consisted of the deputy head of curriculum and two subject teachers. Data analysis was conducted using an interactive model that includes data reduction, data presentation, and conclusion drawing. The results show that academic supervision is carried out systematically in three main stages: planning, implementation and evaluation. The madrasah head develops the supervision program collaboratively with senior teachers. Supervision is conducted through classroom observation and direct feedback. Evaluation of the results of supervision results in improvements in teacher competencies, both from the pedagogical, professional, personality and social aspects. Based on these findings, it can be concluded that the academic supervision implemented contributes positively to improving teachers' professionalism and the quality of learning in madrasah.
