Peningkatan Kemampuan Penalaran Matematika Melalui Pembelajaran Berdiferensiasi di SMP Negeri 4 Waru
Abstract
Kemampuan penalaran matematika sangat penting dikembangkan dalam proses pembelajaran matematika. Akan tetapi pada kenyataannya, masih banyak peserta didik yang memiliki kemampuan penalaran matematika yang rendah. Salah satu faktor yang menyebabkan rendahnya kemampuan penalaran peserta didik dalam belajar matematika adalah karena pembelajaran yang didominasi oleh guru. Salah satu metode pembelajaran yang dapat digunakan adalah pembelajaran berdiferensiasi yang dapat memfasilitasi kebutuhan dan karakteristik peserta didik. Jenis penelitian ini adalah Penelitian Tindakan Kelas (PTK). Penelitian ini dilaksanakan di SMP Negeri 4 Waru pada tahun ajawa 2022/2023. Subjek penelitian ini adalah peserta didik kelas VII-3 yang berjumlah 36 peserta didik. Penelitian ini dilakukan melalui tiga tahapan yaitu perencanaan (plan), pelaksanaan (do), dan pengamatan dan refleksi (see), dimana penelitian ini akan berhenti jika terdapat peningkatan kemampuan penalaran matematika peserta didik. Hasil data yang diperoleh menunjukkan bahwa pembelajaran berdiferensiasi mampu meningkatkan kemampuan penalaran matematika peserta didik. Pembelajaran berdiferensiasi telah meningkatkan kemampuan penalaran matematika peserta didik kelas VII-3 SMP Negeri 4 Waru. Pada saat awal, kemampuan penalaran matematika peserta didik kelas VII-3 SMP Negeri 4 Waru mencapai 20% dengan kualifikasi sangat rendah. Pada siklus I, kemampuan penalaran matematika peserta didik kelas VII-3 SMP Negeri 4 Waru meningkat menjadi 53% dengan kualifikasi sangat rendah. Pada siklus II, kemampuan penalaran matematika peserta didik kelas VII-3 SMP Negeri 4 Waru meningkat menjadi 70% dengan kualifikasi sedang.

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.
