Creative thinking is an essential skill that elementary school students must possess to face the challenges of the 21st century. The purpose of this study is to analyze the impact of improving and achieving students' mathematical creative thinking abilities through the intervention of Augmented Reality (AR)-based learning. Two groups of students were involved: an experimental group that received AR-based learning and a control group that underwent conventional learning. The aspects of creative thinking abilities measured included fluency, flexibility, elaboration, and originality. These aspects were evaluated through pre-tests and post-tests. A total of 62 students participated in this study, consisting of 32 students in the experimental group and 30 students in the control group. Data were collected using essay tests designed to measure students' creative thinking abilities. The results of the mean difference test showed that the experimental group achieved significant improvement in creative thinking abilities compared to the control group. AR proved effective in enhancing student engagement and mathematical creative thinking abilities, particularly in the aspects of fluency and flexibility. This study recommends the use of AR as an innovative tool for mathematics learning in elementary schools.
