Meningkatkan Keaktifan Dan Hasil Belajar Peserta Didik Melalui Model PBL Pada Materi Persamaan Garis Lurus
Abstract
Penelitian ini dilatarbelakangi oleh kurangnya keaktifan dan hasil belajar peserta didik yang rendah dalam pembelajaran matematika. Untuk meningkatkan keaktifan dan hasil belajar peserta didik, peneliti menggunakan model Problem Based Learning. Tujuan penelitian ini untuk meningkatkan keaktifan dan hasil belajar peserta didik dengan menggunakan model pembelajaran problem based learning. Penelitian ini merupakan penelitian tindakan kelas, dengan populasi adalah peserta didik kelas VIII SMP Lentera Kasih Bali Tahun Ajaran 2020/2021. Teknik pengumpulan data untuk keaktifan peserta didik adalah observasi dan pengisian angket keaktifan, sedangkan untuk pengumpulan data hasil belajar menggunakan tes. Berdasarkan hasil penelitian, dapat disimpulkan bahwa: (1) Keaktifan belajar peserta didik meningkat dalam mengikuti pembelajaran dengan model problem based learning (nilai rata-rata keaktifan peserta didik berdasarkan observasi untuk siklus 1, siklus 2, dan siklus 3 berturut-turut adalah 73, 78, dan 82, sedangkan berdasarkan angket keaktifan berturut-turut adalah 69, 78, dan 82). (2) Hasil belajar peserta didik meningkat dalam mengikuti kegiatan pembelajaran dengan model problem based learning pada materi persamaan garis lurus (nilai rata-rata hasil belajar peserta didik untuk siklus 1, siklus 2, dan siklus 3 berturut-turut adalah 44,8; 70,7; dan 79,6)

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.
