PENINGKATAN PRESTASI BELAJAR MATEMATIKA PESERTA DIDIK MELALUI PENERAPAN MODEL KOOPERATIF TIPE THINK-PAIR-SHARE MATERI TRIGONOMETRI KELAS X MIPA 1 SMA NEGERI 1 TAMBAKREJO
Abstract
Penelitian ini bertujuan untuk meningkatkan prestasi belajar matematika peserta didik melalui penerapan model kooperatif tipe Think-Pair-Share materi Trigonometri kelas X MIPA 1 SMA Negeri 1 Tambakrejo. Penelitian ini dilakukan karena peserta didik kesulitan dalam memahami konsep yang sebelumnya telah diketahui oleh peserta didik dengan konsep baru yang akan dipelajari. Peserta didik juga masih kesulitan dalam menyelesaikan soal matematika terkait masalah kehidupan sehari-hari karena kurangnya pemahaman konsep pada materi sebelumnya.
Penelitian ini menggunakan penelitian tindakan kelas dengan subjek penelitian peserta didik kelas X MIPA 1 SMA Negeri 1 Tambakrejo. Metode pengumpulan data pada penelitian ini adalah menggunakan tes. Instrumen penelitian ini adalah lembar tes materi Trigonometri.
Hasil penelitian ini adalah pembelajaran dengan penerapan model kooperatif tipe Think-Pair-Share materi Trigonometri kelas X MIPA 1 SMA Negeri 1 Tambakrejo, karena peserta didik dapat berdiskusi secara berkelompok dengan teman sebangku. Berdasarkan tes awal, penelitian siklus I, dan siklus II yang dilakukan kepada peserta didik menunjukkan bahwa peserta didik presstasinya meningkat dari 21,42 % pada siklus I kemudian meningkat 64,28 % pada siklus II.

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.
