Abstract: This research aims to develop and validate an Augmented Reality (AR)-based mobile learning tool designed for electrical circuit courses, improving students’ understanding through interactive simulations. This study adopted the Borg and Gall development model, which was simplified into five main stages: analysis, development, validation, pilot testing, and implementation. The study used a one-group pre-test-post-test design involving 30 students. The validation results showed high content validity, with scores of 0.81 from material experts and 0.93 from media experts, confirming its suitability for teaching. The practicality test revealed high usability, scoring 81.63% in the limited trial and 88.23% in the full implementation. The effectiveness test showed significant learning improvement, with an N-Gain score of 0.48 (medium) and t-test results (p = 0.001) showing statistically significant performance improvement. These findings highlight the ability of AR tools to improve engagement, understanding, and performance in electrical circuit courses, offering an immersive and scalable learning solution. However, the focus of this study was limited to electrical circuits, without exploring the adaptation of AR for other subjects. In addition, issues such as access to compatible devices and the digital literacy gap were not fully addressed. Future research should explore AR applications in other fields, examine the long-term impact on knowledge retention, and incorporate personalization features to increase inclusivity. This research contributes to the use of mobile AR in education, demonstrating its potential for wider adoption in engineering and technical disciplines.
