Abstract

Penelitian ini dilatarbelakangi oleh adanya permasalahan mengenai tingkat penguasaan konsep matematis yang rendah mengenai perkalian bilangan cacah sampai 100 pada siswa SD fase B. Berdasarkan temuan dari studi awal yang dilakukan di salah satu sekolah dasar, serta hasil telaah terhadap berbagai penelitian sebelumnya, ditemukan adanya indikasi bahwa salah satu penyebabnya adalah proses pembelajaran yang belum mengintegrasikan penggunaan bahan ajar yang bersifat kontekstual dan relevan dengan kehidupan siswa. Menanggapi permasalahan tersebut, diperlukannya bahan ajar berbasis pendekatan matematika yaitu bahan ajar “KOPER” berbasis RME. Penelitian ini bertujuan untuk menguji apakah implementasi bahan ajar “KOPER” berbasis RME memberikan pengaruh terhadap peningkatan kemampuan pemahaman konsep matematis siswa SD fase B khususnya pada materi perkalian bilangan cacah sampai 100. Metode penelitian yang digunakan adalah kuantitatif dengan desain quasi experiment, dalam bentuk non-equivalent control group design. Subjek dalam penelitian ini adalah siswa kelas III sekolah dasar, yang terbagi menjadi dua kelompok, yaitu kelompok kontrol dan kelompok eksperimen yang masing-masing terdiri dari 20 orang. Pengumpulan data dalam penelitian ini dilakukan melalui instrumen tes berupa pre-test dan post-test. Hasil penelitian ini menunjukkan bahwa implementasi bahan ajar “KOPER” yang berorientasi pada Realistic Mathematics Education (RME) berpengaruh dalam meningkatkan kemampuan siswa untuk memahami konsep khususnya materi perkalian pada siswa SD fase B. This research is motivated by the problem of the low level of mastery of mathematical concepts regarding multiplication of whole numbers up to 100 in elementary school students in phase B. Based on the findings of an initial study conducted in an elementary school, as well as the results of a review of various previous studies, it was found that one of the causes was the learning process that had not integrated the use of contextual and relevant learning materials to students' lives. In response to this problem, learning materials based on a mathematical approach were needed, namely the RME-based “KOPER” teaching materials. This study aims to examine whether the implementation of RME-based “KOPER” learning materials has an effect on improving the ability to understand mathematical concepts of elementary school students in Phase B, especially in the topic of multiplication of whole numbers up to 100. The research method used is quantitative with a quasi-experimental design in the form of a non-equivalent control group design. The subjects of this study were third-grade elementary school students, divided into two groups: a control group and an experimental group, each consisting of 20 students. Data collection was carried out using test instruments in the form of pretests and posttests. The results of this study indicate that the implementation of the “KOPER” learning material oriented towards Realistic Mathematics Education (RME) has an effect on improving students' ability to understand concepts, especially the multiplication material in elementary school students in phase B.
