Abstract

ABSTRAK Pembelajaran matematika banyak berorientasi pada bagaimana cara mengembangkan dan meningkatkan kemampuan penalaran siswa dalam menyelesaikan penalaran-penalaran matematika agar matematika lebih bermakna dalam kehidupan siswa. Tujuan penelitian ini adalah untuk mengetahui peningkatan kemampuan penalaran matematis siswa melalui pendekatan Contextual Teaching and Learning. Penelitian ini merupakan penelitian kuasi eksperimen. Penelitian ini dilakukan di SMP Negeri 1 Pangkalan Susu Tahun Ajaran 2023/2024. Teknik pemilihan sampel yang digunakan adalah teknik sampling purposive. Populasi penelitian ini seluruh siswa kelas VIII. Sampel dalam  penelitian ini sebanyak 2 kelas, yaitu kelas VIII-2 yang dijadikan sebagai kelas eksperimen dan kelas VIII-3 dijadikan sebagai kelas kontrol. Instrumen yang digunakan adalah tes yang berbentuk uraian pada materi Teorema Pythagoras. Hasil dari penelitian Ini menunjukkan bahwa peningkatan kemampuan penalaran matematis siswa melalui pendekatan Contextual Teaching and Learning lebih tinggi daripada kemampuan penalaran matematis siswa yang melalui pembelajaran konvensional. Kata Kunci: Contextual Teaching and Learning, Kemampuan Penalaran Matematis     ABSTRACT Mathematics learning focuses a lot on how to develop and improve students' reasoning abilities in completing mathematical reasoning so that mathematics is more meaningful in students' lives. This study aims to know the increasing of mathematical reasoning ability using Contextual Teaching and Learning approach. This research is a quasi experiment research. This research was conducted at SMP Negeri 1 Pangkalan Susu Academic Year of 2023/2024. The sample technique used is purposive sampling. The population of this study were all class VIII students. The sample in this study consisted of 2 classes, namely class VIII-2 which was used as the experimental class and class VIII-3 which was used as the control class. The study involved the type of instrument, namely a test in the form of description test on Pythagoras Theorem. The result of this research show  that the increase in students' mathematical reasoning abilities through the Contextual Teaching and Learning approach is higher than students' mathematical reasoning abilities through conventional learning. Keywords: Contextual Teaching and Learning, Mathematical Reasoning Ability
