Pengembangan E-Modul Berbasis Masalah dengan Pendekatan Etno-STEM pada Materi Gelombang Bunyi untuk Meningkatkan Minat dan Hasil Belajar Peserta Didik

Abstract

Learners' perception that physics is difficult and low interest in learning cause learning outcomes to decline. The Problem-Based Learning (PBL) model encourages students' activeness through exploration and discussion, while the ethno-STEM approach makes learning contextual with Javanese culture by improving 21st century skills. This study aims to develop a problem-based e-module with an ethno-STEM approach on sound waves material to increase interest and learning outcomes. Using the Research and Development (R&D) research type with the ADDIE method and One Group Pre-Test Post-Test design, small-scale trials were conducted in class XII-9 and large-scale in class XI-4 SMA Negeri 1 Ngawen. The results showed: (1) E-modules obtained an average score from validators of 89.42% with a very feasible category; (2) Learning interest increased by 4.25% with N-gain 0.13 and effect size 1.651, while learning outcomes increased by 27.21% with N-gain 0.46 and effect size 1.800. There was a moderately positive correlation between the increase in interest and learning outcomes (0.456); (3) Practicality reached 76.04% (class XII-9) and 73.92% (class XI-4) with the practical category. Problem-based e-modules with ethno-STEM approach proved to be feasible, effective, and practical for learning sound waves.
