Pengembangan E-LKPD berbasis Liveworksheet Materi Gaya dan Pengaruhnya terhadap Gerak Benda Siswa Kelas IV Mata Pelajaran IPAS di SD

Abstract

This study aims to develop a valid and practical teaching material in the form of a Liveworksheet-based electronic student worksheet (E-LKPD) covering the topic of forces and their effects on object motion for fourth-grade students in the Science and Social Studies (IPAS) subject. The study was motivated by issues such as low student engagement and learning outcomes, a lack of interactive teaching materials, and the suboptimal use of technology in the learning process. The research employed the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The developed E-LKPD features an attractive and interactive interface, is easily accessible via digital devices, and supports independent student learning. The study involved three instrument validation experts, six product testing experts, one senior teacher (Group IV), two other teachers, and sixteen fourth-grade students from Cluster II, Kubutambahan District. Data collection methods included observation, interviews, and questionnaires. The results indicate that the Liveworksheet-based E-LKPD is highly valid, with validation scores of 0.93 for material content, 0.97 from material experts, and 0.94 from language experts. Furthermore, practicality testing yielded a score of 98% from teachers and 96 % from students, indicating that the developed product falls into the "highly practical" category.
