Abstract

Penelitian ini bertujuan untuk mendeskripsikan kemampuan penalaran matematis siswa kelas VII dalam memahami materi penyajian data dan diagram. Pendekatan penelitian yang digunakan adalah kualitatif, dengan jenis penelitian fenomenologi. Partisipan yang dilibatkan adalah 31 siswa dari salah satu SMP Negeri di Kota Pekanbaru. Pengumpulan data dilakukan melalui tes tertulis, wawancara, observasi, dan dokumentasi. Hasil penelitian menunjukkan bahwa mayoritas siswa 61,29% memiliki kemampuan penalaran matematis yang sangat baik, sementara 19,35% siswa tergolong baik dan 19,35% lainnya tergolong cukup. Temuan ini mengindikasikan bahwa sebagian besar siswa telah memahami konsep dasar dan mampu menyelesaikan soal dengan pendekatan yang logis serta sistematis. Namun demikian, masih terdapat sebagian siswa yang mengalami kesulitan dalam menafsirkan data dan menyusun langkah penyelesaian secara tepat. Hal ini menunjukkan perlunya penerapan strategi pembelajaran kontekstual yang dapat mengaitkan konsep matematika dengan pengalaman sehari-hari siswa. Dengan pendekatan tersebut, Pembelajaran matematika perlu dirancang lebih kontekstual dan reflektif agar dapat mendukung perkembangan penalaran siswa secara menyeluruh. Dapat diharapkan penalaran matematis siswa dapat berkembang secara optimal dan merata.

Abstract

Purpose – Mathematical connection ability is a high-order thinking skill necessary for linking mathematical concepts across topics, disciplines, and real-life contexts. Preliminary observations suggest that many students struggle to establish these connections, particularly when learning the Pythagorean Theorem. Methodology – This study employed a qualitative descriptive research design using a case study method. The sample consisted of 22 students, with four participants purposively selected to represent varying levels of mathematical connection ability. Data were collected through a six-item written test developed based on NCTM indicators and supported by semi-structured interviews for triangulation. Data were analyzed qualitatively to identify patterns in students' mathematical connection performance. Findings – The study found that students generally demonstrated high levels of mathematical connection ability, with a mean score of 70.26%. Most students were able to connect mathematical concepts across different topics and disciplines. However, they encountered difficulties in applying mathematical ideas to real-life situations. These findings highlight the gap between theoretical understanding and practical application. Novelty – This study contributes to the literature by providing in-depth insights into students’ levels of mathematical connection ability, particularly in contextual problem-solving involving the Pythagorean Theorem. Significance – The findings are beneficial for mathematics educators, curriculum designers, and educational policymakers to enhance instructional strategies and support applied mathematical thinking in students.
