Development of an Interactive Mathematics E- Worksheet (E-LKPD) on the Area of Plane Figures for Grade III Students at SDN 3 Panjerejo Using Liveworksheet

Abstract

In today's evolving educational landscape shaped by Society 5.0, technology plays a vital role in making learning more meaningful, interactive, and accessible—especially for young learners. This research focuses on creating an Interactive Electronic Student Worksheet (E-LKPD) using the Liveworksheet platform, aimed at helping third-grade elementary students better understand the concept of area in plane figures. The development followed the 4D model by Thiagarajan, Semmel, and Semmel, which includes four core stages: Define, Design, Develop, and Disseminate.The study was conducted at SDN 3 Panjerejo, where early observations showed that many students faced challenges in understanding geometry due to a lack of visual learning tools and engaging activities. To address this, a digital worksheet was designed with a blend of images, text, interactive tasks, and real-time feedback to support student learning. Various tools were used to evaluate the product, including validation sheets from experts, questionnaires for students and teachers, and classroom observations. The results showed strong validation from material experts (94%), media experts (97%), and practitioners (92.5%), indicating high levels of reliability and relevance. In trials, students responded very positively—with 96.6% satisfaction in small groups and 97.7% in larger groups. These findings highlight the potential of interactive E-LKPDs to not only support conceptual understanding but also encourage student independence and motivation. This product aligns with the goals of the Kurikulum Merdeka and provides meaningful insights for the development of digital learning materials in primary education.
