- This study provides a thorough assessment of the user experience of an augmented reality (AR) e-learning application specifically developed for the 9th-grade physics chapter on Work and Energy. The study employs an experimental methodology and applies the System Usability Scale (SUS) to examine several aspects of usability and user perception. The findings, presented using pie charts and in-depth talks, demonstrate a favorable student attitude towards the AR application, suggesting a high level of agreement about its frequency of usage, user-friendliness, and integration of features. A significant majority strongly disagreed with the view of the system being complex, the requirement for technical assistance, and inconsistency, hence reaffirming the user-friendly characteristics of the program. The research highlights specific areas that can be enhanced, proposing future efforts in refining the content and features, incorporating adaptive learning methodologies, and investigating extended reality technology. Furthermore, it is advisable to take into account accessibility, incorporate collaborative learning functionalities, and provide instruction for educators in order to maximize the application's effectiveness in various educational environments. The findings provide useful insights for further enhancing and refining AR e-learning apps, hence promoting a more immersive and efficient teaching experience for 9th-grade physics students.
