Modul Ajar, Sistem Persamaan Linear Dua Variabel, Problem Solving
Abstract
Tujuan penelitian ini adalah menghasilkan produk berupa modul ajar berbasis problem solving melalui pemahaman pemecahan masalah pada materi sistem persamaan linear dua variabel. Metode yang digunakan dalam penelitian ini adalah metode pengembangan Research and Development (R&D) dengan model pengembangan ADDIE. Hasil penelitian ini ditinjau dari kevalidan dan keefisienan produk. Kevalidan produk diperoleh dari nilai rata-rata yang diberikan oleh 3 validator pada angket validasi sebesar 89,7 masuk pada interval >81 dengan kriteris sangat valid. Sedangkan keefisienan produk diperoleh dari nilai rata-rata yang diberikan oleh responden melalui tahap uji coba skala kecil dengan jumlah responden sebanyak 5 siswa yang memperoleh nilai 82 masuk dalam interval 70,01 – 85 dengan kategori efisien. Sedangkan uji coba skala besar dengan jumlah responden sebanyak 32 siswa memperoleh nilai 94,5 masuk dalam interval >85,01 dengan kategori sangat efisien. Berdasarkan hal tersebut dapat disimpulkan bahwa produk yang telah dikembangkan oleh peneliti berupa modul ajar sangat valid, sangat efisien, dan sesuai dengan kebutuhan siswa.
