Abstract

Tujuan dari penelitian ini adalah mendeskripsikan dan mengetahui keefektifan penerapan model Pembelajaran Matematika Realistik (PMR) dalam meningkatkan kemampuan siswa memahami pokok bahasan Bilangan Bulat pada siswa kelas VII salah satu SMP Negeri di Kota Kupang. Penelitian ini merupakan penelitian tindakan kelas, data dikumpulkan melalui observasi dan tes. Observasi dilakukan pada pra siklus dan pada setiap siklus, sedangkan tes dilakukan pada pra siklus, akhir setiap siklus dan pada akhir dari semua siklus penelitian. Berdasarkan hasil analisis deskriptif terhadap data observasi dan data hasil tes, disimpulkan bahwa; rata-rata data hasil observasi maupun rata-rata data hasil tes menunjukkan adanya peningkatan. Data hasil observasi kemampuan guru mengelola pembelajaran mengalami peningkatan dari siklus I ke siklus II sebesar 0,72. Rata-rata aktivitas siswa juga mengalami peningkatan dari siklus I ke siklus II sebesar 0,91. Rata – rata hasil tes belajar siswa pun menunjukkan peningkatan dari siklus I ke siklus II sebesar 2,89. Dan rata-rata ketuntasan hasil tes siswa secara klasikal juga mengalami peningkatan, yaitu sebesar 25,71%. Pada tes akhir, siswa yang memperoleh skor minimal 60 sebanyak 88,57%. Karena ketuntasan hasil belajar secara klasikal tercapai, kemampuan guru mengelola pemblajaran efektif, aktivitas siswa dalam pembelajaran efektif dan respon siswa terhadap pembelajaran positif, maka dapat disimpulkan bahwa penerapan model PMR dapat meningkatkan kemampuan siswa memahami materi Bilangan Bulat di SMP kelas VII.

Abstract

Indonesian students’ mathematical literacy skills, particularly in algebra, are still relatively low, as shown by the results of PISA 2022. A significant contributing factor is the limited relevance of teaching materials to students’ real-life contexts. This study introduces an innovative approach by developing algebra teaching materials based on local wisdom—referred to as local wisdom literacy—as a meaningful context for improving mathematical literacy among seventh-grade junior high school students. The novelty of this study lies in the integration of traditional Timorese cultural practices, such as weaving patterns, local measurement systems, and indigenous numerical reasoning, into formal algebra instruction. Using the ADDIE development model, this Research and Development (R&D) study produced culturally embedded materials that were validated by experts, with validity scores of 85.4% for content and 85% for assessment instruments. The materials were also considered highly practical (96.93% by students, 96% by teachers) and effective, as indicated by a moderate average N-Gain of 0.42 in student learning outcomes. In addition to improving conceptual understanding and mathematical literacy, the developed materials serve as a culturally responsive pedagogical model that is in line with the objectives of the Merdeka Curriculum and supports the preservation of local culture. This study provides a contextual and humanistic alternative in algebra learning, which offers pedagogical value and cultural significance
