Development of 3D Visualization Media Using Assemblr Studio for Learning Polyhedral Geometry

The integration of technology in education has significantly transformed the teaching and learning process, especially in subjects like geometry, which heavily rely on spatial visualization. Students’ understanding of polyhedral geometry concepts is often hindered by the limitations of two-dimensional representations found in textbooks. Recent technological advancements have enabled 3D visualization to become an innovative solution for enhancing conceptual understanding in geometry. This study employs the Plomp development model, which consists of three phases. In the preliminary research phase, it was found that students struggle to understand polyhedral geometry due to limitations in visual representation. In the prototyping phase, an interactive and engaging 3D visualization medium was developed. In the assessment phase, media feasibility testing was conducted, focusing on expert validation and practical testing with students. The validation was carried out by three experts: a media expert, a subject matter expert, and an educational expert. The validation results indicated that the developed 3D visualization media achieved a very high level of validity, with an average score of 90.7%. Furthermore, the average practicality score was 79%, categorized as practical. The findings of this study demonstrate that the use of 3D visualization media based on Assemblr Studio is feasible for teaching polyhedral geometry.
