Developing a Genially-Based Physics E-Module Using the ADDIE Model: Boosting High School Student’s Learning Outcomes on Static Fluids

Abstract

Physics concepts are often perceived as abstract and difficult, highlighting the urgent need for interactive digital learning media that align with 21st-century educational demands. This study aims to develop a Genially-based physics e-module on static fluid material for high school Phase F, validate its quality, and evaluate its effectiveness in classroom learning. This research and development (R&D) study applied the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model. The subjects involved 117 eleventh-grade students from SMA Batik 2 Surakarta, selected using a cluster random sampling technique. Data were collected through validation questionnaires and a pretest-posttest design to measure learning outcomes. The results showed that the developed e-module achieved high validity, with scores of 90/100 from expert lecturers and 96/100 from physics teachers, complemented by "Very Good" ratings across one-on-one, small-scale, and field trials. Furthermore, the e-module was proven highly effective, as evidenced by a significant increase in students' average scores from 43.75 on the pretest to 81.25 on the posttest, yielding a high-category N-gain score of 0.89. In conclusion, the Genially-based physics e-module serves as a valid and highly effective digital learning resource that substantially enhances students' conceptual understanding and supports independent learning in physics education.
