Pengembangan LKPD Berbasis Discovery Learning pada Materi Elastisitas dan Hukum Hooke di SMAS Free Methodist Medan

Abstract

This Study aims to develop a physics Student Worksheet (LKPD) based on discovery learning approach for Elasticity dan Hooke’s Law Topics, evaluate its feasibility for school implementation, and analize student responses. This research adopted a Research and Development (R&D) design, modifying the 4D model into 3D model (Define, Design, Develop). The subjects consistend of 28 eleventth-grade students at SMAS Free Methodist Medan. Data collection instruments include material validation questionnaires. The findings revealed validation scores of 84.36 % from the lecturer material expert, 86,45% from the teacher material expert, and 85.83% from the media expert, all falling under the “Very Feasible”category. Additionally, the student response score reached 85,42% categorized as “Very Practical”. Consequently, the discovery learning-based physics LKDP is proven feasible and practical for physics instruction in senior high schools.
