Augmented Reality Learning Media Using on Geometry Materials to Enhance Student Learning Outcomes
Keywords:
Augmented Reality, Geometry, ADDIE Model, Innovative Learning, TPCKAbstract
The fundamental problem addressing this research is the persistent difficulty elementary students face in visualizing three-dimensional geometric concepts, leading to low motivation and suboptimal learning outcomes. This study aims to: (1) develop a valid Augmented Reality (AR) learning media using the Assemblr application; (2) assess its practicality among teachers and students; and (3) evaluate its effectiveness in improving student learning outcomes. Employing a Research and Development (R&D) approach with the ADDIE model, this study was conducted in Pangkajene District involving 47 students across two trial cycles. Data were collected via expert validation, questionnaires, and pretest-posttest designs. The results indicate that the AR media is "Very Valid" (4.12/5.00) and "Practical" for classroom use. Crucially, the media proved effective, raising classical mastery from 80% in Trial I to 96.3% in Trial II. The findings suggest that AR bridges the gap between abstract mathematical objects and concrete operational cognitive stages. Future research should integrate the Technological Pedagogical Content Knowledge (TPCK) framework to further empower teachers in developing similar adaptive technologies.
