PENERAPAN DISCOVERY LEARNING DENGAN STRATEGI REACT UNTUK MENINGKATKAN AKTIVITAS DAN HASIL BELAJAR PESERTA DIDIK KELAS XI-B SMA PLUS AR-RAHMAT BOJONEGORO MATERI POLINOMIAL
Abstract
Hasil pengamatan yang dilakukan di kelas XI-B SMA Plus Ar-Rahmat Bojonegoro menunjukkan bahwa sebagian besar peserta didik mengalami kesulitan pada materi polinomial. Kesulitan yang dialami peserta didik diduga karena guru lebih sering mengajar dengan model pembelajaran ekspositori sehingga peserta didik kurang aktif dalam proses belajar mengajar dan menyebabkan hasil belajar peserta didik kurang maksimal. Maka, perlu diterapkan metode pembelajaran yang dapat meningkatkan aktivitas dan hasil belajar peserta didik, yaitu discovery learning dengan strategi REACT. Penelitian ini dilaksanakan dengan tujuan untuk mendeskripsikan langkah-langkah pembelajaran discovery learning dengan strategi REACT yang dapat meningkatkan aktivitas dan hasil belajar peserta didik kelas XI-B SMA Plus ArRahmat Bojonegoro materi polinomial.
Penelitian ini merupakan Penelitian Tindakan Kelas (PTK). Data penelitian berupa daftar nilai peserta didik pada tes di tiap akhir siklus dan data hasil observasi yang didapatkan dari observer. Pengumpulan data dilakukan dengan teknik observasi, angket, lembar penilaian aktivitas peserta didik, tes, catatan lapangan, dan dokumentasi. Data yang terkumpul dianalisis secara kualitatif dan kuantitatif.
Berdasarkan hasil analisis tersebut, diperoleh dua kesimpulan sebagai berikut. Pertama, bahwa penerapan discovery learning dengan strategi REACT pada materi polinomial yang dapat meningkatkan aktivitas dan hasil belajar peserta didik kelas XI-B SMA Plus Ar-Rahmat Bojonegoro memiliki langkah-langkah: 1) guru memberikan apersepsi dan motivasi; 2) menerapkan discovery learning dengan strategi REACT dengan tahapan: stimulation, problem statement, data collection, data processing, dan verification; 3) peserta didikmengomunikasikan hasil diskusi kelompok kemudian bersama-sama guru membuat kesimpulan. Kedua, bahwa pembelajaran dengan discovery learning dengan strategi REACT meningkatkan aktivitas dan hasil belajar peserta didikkelas XI-B SMA Plus Ar-Rahmat Bojonegoro. Skor rata-rata aktivitas peserta didik pada siklus I sebesar 27,5 dengan kategori baik, tetapi masih ada poin pengamatan yang bernilai 2. Skor rata-rata aktivitas peserta didik pada siklus II sebesar 35,5 dengan kategori sangat baik, dan setiap poin pengamatan mencapai minimal nilai 3. Hasil tes peserta didik pada siklus I menunjukkan bahwa 60% peserta didik yang memperoleh nilai mencapai KKM dengan rata-rata hasil tes yang diperoleh adalah sebesar 78,25. Hasil tes peserta didik pada siklus II menunjukkan bahwa 90% peserta didik yang memperoleh nilai mencapai KKM dengan rata-rata hasil tes yang diperoleh adalah sebesar 85,45.

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.
