Laboratory environments play a vital role in developing scientific skills, however pose risks due to hazardous materials and inadequate safety comprehension among junior high school students. This study developed and evaluated Virtual Reality (VR)-based instructional media to improve students’ understanding of laboratory safety procedures. Using the 4D Research and Development model (Define, Design, Develop, Disseminate), the VR module was assessed through expert validation, pre-test and post-test, and usability analysis. Expert evaluations rated the learning media as highly feasible, with an average score of 4.5 out of 5. Testing with 35 seventh-grade students showed significant knowledge improvement, with mean scores rising from 57.71 to 85.43, equaling a 48.03% increase. Usability, measured using the System Usability Scale (SUS), yielded a score of 85.6, indicating excellent user satisfaction. These results suggest that VR-based learning media is an effective, engaging, and user-friendly tool for enhancing laboratory safety education in junior high school settings. ©2025 IEEE.
