3d Hologram as Scientific Tool in Geometry Educational

Abstract

Learning geometry must begin in a simple way from concrete to abstract, from an intuitive perspective to analysis, from exploration to long-term mastery. 3D Holograms are need to assist teachers and students in learning geometry. This research develops a valid, practical and effective 3D Hologram. Research and development used the ADDIE model. The 3D Hologram is validated by material and media experts and field tested. Data analysis used quantitative analysis. The results found 3D Hologram valid with a score of 75, practical with a score of 91, and effective with a score of 87. 3D Hologram as scientific tool in geometry education.
