Abstract

The Covid-19 pandemic has made learning activities carried out online so that many students have difficulty understanding the material, so interesting learning media are needed with flexible access. This study aims to develop a learning video with a culture-based RME approach on congruence and similarity materials and to determine the validity and practicality of the product. This type of research is development research with the ADDIE research model. The subjects of this study were students of class IX A MTs Negeri 9 Bantul. The data collection methods are interviews and questionnaires. The data analysis step is carried out by calculating and analyzing the results of the validity and practicality tests. The results of the product validity test obtained very valid criteria with an average value of 4.75 by material experts and 4.82 by media experts. At the same time, the practicality test got a percentage of 91.82% with very practical criteria in small class trials and a percentage of 82.67% with very practical criteria in large class trials. Based on these results, the learning video can be declared very valid and very practical to use in learning.

Abstract

Penelitian ini dilatarbelakangi oleh perlunya bahan ajar berbasis teknologi yang dapat mendukung siswa dalam mempelajari materi Sistem Persamaan Linear Dua Variabel (SPLDV) sekaligus melatih kemampuan literasi matematis. Namun, penelitian yang mengembangkan E-LKPD berbasis Liveworksheets yang secara khusus mengintegrasikan aktivitas literasi matematis pada materi SPLDV masih terbatas. Penelitian ini memiliki tujuan untuk mengembangkan E-LKPD berbantuan Liveworksheets yang mengintegrasikan komponen literasi matematis, serta menguji tingkat validitas dan kepraktisannya. Metode yang diterapkan dalam penelitian ini yaitu Research and Development (R&D) dengan tahapan pengembangan yang berpedoman pada model ADDIE. Penelitian ini melibatkan 20 siswa kelas VIII dari salah satu SMP di Bantul sebagai subjek penelitian. Hasil uji validitas E-LKPD pada aspek materi dan media berturut-turut sebesar 74 dan 88. Kedua skor tersebut berada pada kategori baik, yang menunjukkan bahwa E-LKPD yang dikembangkan valid. Penilaian terhadap kepraktisan memperoleh skor 84,05 yang termasuk kategori sangat baik sehingga produk dapat dinyatakan sangat praktis. Berdasarkan temuan tersebut, E-LKPD yang dikembangkan dapat disimpulkan valid dan sangat praktis, serta layak digunakan dalam proses pembelajaran.
