This study aims to develop Augmented Reality (AR) media integrated with Project-Based Learning (PjBL) and examine its feasibility, practicality, and effectiveness in improving elementary school students’ creative thinking skills. The research employed a research and development (R&D) method using a simplified development model consisting of analysis, design, development, implementation, and evaluation stages. The subjects of the study were elementary school students who participated in the learning process using the developed AR media. The data were collected through expert validation questionnaires, student and teacher response questionnaires, and creative thinking skills tests (pre-test and post-test). The data were analyzed descriptively using quantitative and qualitative analysis techniques. The feasibility of the media was determined through expert validation, practicality was measured based on student and teacher responses, and effectiveness was analyzed using pre-test and post-test results along with N-gain scores. The results showed that the AR media obtained a very good validity score of 4.45, indicating that it is highly feasible for use in learning. The practicality results showed positive responses from students (88%) and teachers (91%), categorized as very practical. Furthermore, the effectiveness test showed an increase in students’ creative thinking skills, with an average pre-test score of 62.30 and post-test score of 84.75, and an N-gain value of 0.60 in the moderate category. These findings indicate that the developed AR media is feasible, practical, and effective in improving students’ creative thinking skills. In conclusion, the integration of Augmented Reality with Project-Based Learning provides an innovative and effective learning approach that enhances student engagement and supports the development of creative thinking skills in elementary education.
