Materi ajar yang berorientasi lingkungan lahan basah belum tersedia di sekolah. Oleh karena itu, dilakukan penelitian dengan tujuan mendeskripsikan kelayakan materi ajar IPA menggunakan model pembelajaran kooperatif berorientasi lingkungan lahan basah. Tujuan khusus penelitian adalah mendeskripsikan: (1) validitas materi ajar, (2) kepraktisan materi ajar, dan (3) efektivitas materi ajar. Jenis penelitian adalah penelitian dan pengembangan dengan menggunakan model pengembangan ADDIE. Subjek ujicoba adalah siswa kelas VIII-B SMP Negeri 27 Banjarmasin. Data diperoleh melalui lembar validasi, lembar pengamatan keterlaksanaan RPP, tes hasil belajar dan lembar kerja siswa. Data dianalisis secara deskriptif kuantitatif dan kualitatif. Hasil penelitian menunjukkan: (1) validitas materi ajar berkategori valid, (2) kepraktisan materi ajar berkategori baik, dan (3) efektivitas materi ajar berdasarkan hasil belajar produk berkategori sedang dan berdasarkan hasil belajar proses berkategori baik. Simpulan penelitian adalah materi ajar IPA menggunakan model pembelajaran kooperatif berorientasi lingkungan lahan basah layak digunakan dalam pembelajaran.Kata kunci: Materi ajar, pembelajaran kooperatif, lahan basah.
This research aims to produce teaching materials in form of Student Activity Sheet (SAS) in transformations for students of class VII SMP/MTs based curriculum 2013 and to test the feasibility of SAS in mathematics learning. This research is a development with the steps of Research and Development (R&D) of ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The research is carried out at SMP N 1 Prambanan Sleman and SMP N 4 Kalasan Sleman. The research data is obtained from the questionnaire evaluation media matter by media matter experts, questionnaire evaluation media by media experts, questionnaire evaluation student responses by students. The research data are analyzed by the process of descriptive analysis and the process of analysis questionnaire with Likert scale. The results showed that the SAS of mathematics developed are good quality with an average percentage of ideals 82,416% and validity criteria by 67,999% < ≤ 83,998%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
