Development of an ADDIE-Based 2D Animation Learning Video to Enhance Elementary School Students’ Understanding of Plane Geometry

Abstract

This study aimed to develop and evaluate the effectiveness of a 2D animation-based learning video on plane geometry using the ADDIE model. The research employed a Research and Development (R&D) method consisting of five stages: Analysis, Design, Development, Implementation, and Evaluation. The study involved 59 fourth-grade students at SDN Gunungsimping 01 Cilacap. Data were collected through observations, interviews, documentation, and pre-test and post-test instruments. The learning media was developed using Adobe Illustrator and Adobe After Effects to present plane geometry concepts in a more interactive and visually engaging form. The effectiveness of the media was analyzed using the N-Gain formula. The results showed that the average score of class 4A increased from 49 to 70.1, while class 4B increased from 20.7 to 48.2. The N-Gain analysis indicated moderate effectiveness, with scores of 0.414 for class 4A, 0.347 for class 4B, and an overall score of 0.374. These findings demonstrate that the developed 2D animation-based learning video effectively improved students’ understanding of plane geometry concepts.
