Purpose- This study aims to determine: (1) the effect of Augmented Reality (AR) on teachers' Technological Pedagogical and Content Knowledge (TPACK); and (2) whether teacher professionalism strengthens the effect of Augmented Reality on TPACK.Methodology- This research employed a quantitative approach using moderated regression analysis (MRA) as the data analysis technique. Data were collected through questionnaires measuring teachers' ability to use ethnomathematics-based Augmented Reality and their TPACK levels.Findings-The results showed that ethnomathematics-based augmented Reality significantly influenced teachers' TPACK, with a significance value of 0.000 0.05 in the moderation test.Contribution- This study reinforces the theoretical framework that integrating augmented Reality with culturally relevant content (ethnomathematics) can effectively enhance teachers' competence in integrating technology, pedagogy, and subject matter
