Pengembangan E-Modul pada Materi Fluida Statis Berbasis Projet Based Learning untuk Meningkatkan Keterampilan Proses Sains Peserta Didik

Abstract

The low Science Process Skills (KPS) and learning motivation in physics students at XI MAN 2 MODEL MEDAN are caused by teacher-centered instruction, theory-only lessons with no practical work, and unengaging teaching materials. This study aims to produce an e-modul based on Project Based Learning (PjBL) on static fluids that is valid, practical, and effective in improving students' KPS. This research and development (R&D) study used the 4-D model, with the stages of define, design, develop, and disseminate. The e-modul was designed using Canva and distributed as a Heyzine flipbook. The research subjects were 31 students of Class XI F-5. Data were collected through expert validation sheets, teacher and student response questionnaires, and pretest and posttest instruments. The results showed that the e-modul was rated as highly valid by the material expert (90.08%) and the media expert (93.6%), and as highly practical by the teacher (94.44%) and students (89.33%). The students' mean score increased from 39.84 on the pretest to 83.55 on the posttest, with an N-Gain of 72.65%, which falls in the high category. The PjBL-based e-modul on static fluids is therefore declared highly valid, highly practical, and effective in improving KPS-based learning achievement.
