VALIDITAS DAN PRAKTIKALITAS E-MODUL INTERAKTIF BERBASIS GUIDED DISCOVERY LEARNING PADA MATERI SISTEM PERIODIK UNSUR UNTUK FASE E SMA

Learning in the digital era encourages us to always develop teaching materials that can help students learn actively, collaboratively and independently. This research aims to develop an interactive e-module based on guided discovery learning on material on the periodic system of elements for the E phase of high school that is valid and practical. The type of research used is Educational Design Research which follows the Plomp development stages. Validation was carried out on five validators who were competent in their fields as well as individual evaluation tests on three students. The small group sample test was carried out on nine students using purposive sampling technique and the practicality test was carried out on two teachers and nine students. The results of the phase I validation test analysis obtained an average V value of 0.73 with an invalid category. The results of the phase II validation test analysis averaged a V value of 0.84 in the valid category. The results of the practicality test analysis of teacher responses with an average percentage of 89.35 in the very practical category. Meanwhile, student responses obtained an average percentage of 86.79%. The results of this analysis explain that the interactive e-module based on guided discovery learning on material on the periodic system of elements for phase E of SMA is declared valid and practical ABSTRAKPembelajarandi era digital mendorong untuk selalu mengembangkan bahan ajar yang dapat membantu peserta didik belajar aktif, kolaboratif dan mandiri. Penelitian ini bertujuan untuk mengembangkan e-modul interaktif berbasis guided discovery learning pada materi sistem periodik unsur untuk fase E SMA yang valid dan praktis. Jenis penelitian yang digunakan yaitu Educational Design Research yang mengikuti tahap pengembangan Plomp. Validasi dilakukan terhadap lima validator yang berkompeten dalam bidangnya serta uji evaluasi perorangan terhadap tiga peserta didik. Uji sampel kelompok kecil dilakukan kepada sembilan orang peserta didik dengan teknik purposive sampling dan uji praktikalitas dilakukan kepada dua orang guru dan sembian peserta didik. Hasil análisis uji validasi tahap I memperoleh rata-rata nilai V 0,73 dengan kategori tidakvali. Hasil analsis uji validasi tahap II rata-rata nilai V 0,84 dengan kategori valid. Hasil análisis uji praktikalitas terhadap respon guru dengan presentase rata-rata sebesar 89,35 dengan kategori sangat praktis. Sedangkan respon peserta didik memperoleh persentase rata-rata sebesar 86,79%. Hasil analsis tersebut menjelaskan bahwa e-modul interaktif berbasi guided discovery learning pada materi sistem periodik unsur untuk fase E SMA dinyatakan valid dan praktis
