Abstract
Geometric thinking is one of the essential skills in 21st-century mathematics education. However, international assessment results indicate that Indonesian students still perform poorly in mathematics, particularly in geometry. Geometry learning in elementary schools tends to rely on rote memorization rather than conceptual understanding. This study aims to develop an Augmented Reality Ethnomathematics-Banten learning media to enhance elementary students^ geometric thinking skills, focusing on plane and solid shapes. The research employed a Research and Development (R&D) method using the ADDIE model, which includes five stages: analysis, design, development, implementation, and evaluation. The findings show that the developed media is feasible based on validations by media, content, and language experts. The implementation stage demonstrated a significant improvement in students^ geometric thinking abilities, with the experimental class achieving a high average N-Gain score. Evaluation through student response questionnaires indicated that the media is highly practical and engaging. Therefore, the Augmented Reality Ethnomathematics-Banten media is effective as an innovative alternative for culturally contextual and interactive mathematics learning.
