Pendekatan Pendidikan Matematika Realistik Indonesia (PMRI): Strategi Meningkatkan Hasil Belajar Matematika Siswa di Sekolah Dasar

This study investigates the application of the indonesian realistic mathematics approach (PMRI) in teaching integers and its impact on students’ learning outcomes. Employing two-cycle classroom action research (CAR) design, the study involved 18 sixth-grade students at MIN 11 Aceh Tenggara in the 2024/2025 school year. Data were collected through structured observation and objective tests and analyzed using Pearson’s product moment correlation. The results showed improvement in both implementation and outcomes: the first cycle reached an average score of 79.31 (good) and the second cycle 92.24 (very good). Student mastery also increased, with 61% exceeding the minimum mastery criteria (KKM) in cycle I and 83% in cycle II. The correlation analysis produced a coefficient of 0.592, indicating a moderate positive relationship between the two cycles.
