KEMAMPUAN KONEKSI MATEMATIKA PESERTA DIDIK DALAM MENYELESAIKAN MASALAH MATEMATIKA PADA MATERI LINGKARAN MELALUI PEMBELAJARAN INKUIRI TERBIMBING DI KELAS VIII SMP MUHAMMADIYAH 4 KEBOMAS
Abstract
Kemampuan koneksi matematika erat kaitannya dengan kemampuan peserta didik dalam
menyelesaikan masalah matematika. Melalui kegiatan menyelesaikan masalah matematika
peserta didik akan berusaha mencari konsep-konsep matematika yang memiliki keterkaitan
dengan masalah yang dihadapi, kemudian menghubungkan konsep-konsep tersebut untuk
menyelesaikannya. Salah satu pembelajaran yang dapat digunakan untuk melatih dan
meningkatkan kemampuan koneksi matematika peserta didik adalah pembelajaran inkuiri
terbimbing. Tujuan penelitian ini adalah untuk mendeskripsikan kemampuan koneksi
matematika peserta didik berkemampuan tinggi, sedang, dan rendah dalam menyelesaikan
masalah matematika pada materi lingkaran melalui pembelajaran inkuiri terbimbing di Kelas
VIII SMP Muhammadiyah 4 Kebomas.
Penelitian ini merupakan penelitian deskriptif kuantitatif. Subjek pada penelitian ini
adalah seluruh peserta didik kelas VIII-A SMP Muhammadiyah 4 Kebomas sebanyak 23
peserta didik. Metode yang digunakan adalah metode tes dan wawancara. Instrumen yang
digunakan dalam penelitian ini adalah tes kemampuan matematika, tes kemampuan koneksi
matematika, lembar validasi soal, dan pedoman wawancara.
Dari hasil analisis data, kemampuan koneksi matematika peserta didik yang
berkemampuan tinggi termasuk kriteria baik dalam menyelesaikan masalah matematika pada
materi lingkaran melalui pembelajaran inkuiri terbimbing dengan rata-rata sebesar 68,06% dan
baik dalam memenuhi ketiga indikator kemampuan koneksi matematika. Kemampuan koneksi
matematika peserta didik yang berkemampuan sedang termasuk kriteria cukup baik dalam
menyelesaikan masalah matematika pada materi lingkaran melalui pembelajaran inkuiri
terbimbing dengan rata-rata sebesar 42,89% dan kurang dalam memenuhi indikator koneksi
antar topik matematika. Kemampuan koneksi matematika peserta didik yang berkemampuan
rendah termasuk kriteria sangat kurang dalam menyelesaikan masalah matematika pada materi
lingkaran melalui pembelajaran inkuiri terbimbing dengan rata-rata sebesar 15,28 dan sangat
kurang dalam memenuhi ketiga indikator kemampuan koneksi matematika.

Open Data and Software Publishing and Sharing
The journal strives to maximize the replicability of the research published in it. Authors are thus required to share all data, code or protocols underlying the research reported in their articles. Exceptions are permitted but have to be justified in a written public statement accompanying the article.
Datasets and software should be deposited and permanently archived inappropriate, trusted, general, or domain-specific repositories (please consult http://service.re3data.org and/or software repositories such as GitHub, GitLab, Bioinformatics.org, or equivalent). The associated persistent identifiers (e.g. DOI, or others) of the dataset(s) must be included in the data or software resources section of the article. Reference(s) to datasets and software should also be included in the reference list of the article with DOIs (where available). Where no domain-specific data repository exists, authors should deposit their datasets in a general repository such as ZENODO, Dryad, Dataverse, or others.
Small data may also be published as data files or packages supplementary to a research article, however, the authors should prefer in all cases a deposition in data repositories.
