<![CDATA[Background: Improving the quality of learning in Islamic education, particularly in fiqh subjects, requires the application of appropriate learning models that actively engage students in the learning process. Objective: This study aimed to determine the extent to which the discovery learning model improves student learning outcomes at MA Nurul Huda Tegal. Method: The research employed the Classroom Action Research (CAR) method and was conducted at Madrasah Aliyah Nurul Huda in 2023. Data were collected through observation, interviews, and tests/evaluations. The analysis focused on students' learning mastery scores. The CAR was carried out in four stages: (1) planning, (2) implementation, (3) observation, and (4) reflection. Result: The findings showed that the implementation of the discovery learning model led to an improvement in student learning outcomes in fiqh subjects. Students became more involved in the learning process and demonstrated better understanding and performance across the assessment stages. Conclusion: The discovery learning model is effective in enhancing students’ learning outcomes. It encourages active participation and fosters the ability to generate and realize creative ideas relevant to real-life contexts. Originality/Value: This study provides practical and pedagogical novelty in the field of Islamic education pedagogy and madrasah teaching methodology by revealing the progressive enhancement of student mastery in fiqh subjects through the discovery learning model within an Islamic senior high school context that has remained insufficiently explored. These findings enrich empirical evidence and serve as a strategic benchmark in applying inquiry based instructional strategies and developing madrasah teacher professional development programs aimed at facilitating abstract normative religious concepts.]]>
