In this study, an m-Learning environment that uses Augmented Reality (AR) as a central tool was successfully implemented to support the development of job skills in a basic carpentry course. The app, designed with visual reinforcements in the form of images, gifs and videos, allowed learners to interact with 3D models of the tool and materials inventory, using augmented reality glasses to enhance the learning experience. The results of the data analysis and discussion revealed several fundamental conclusions: firstly, the AR-assisted visual technique on mobile devices proved to be a highly effective complementary learning tool, highlighting its potential to significantly improve the educational process. Second, the AR tool showed greater effectiveness in low-performing learners, suggesting that this technology may be especially beneficial for those who face challenges in conventional learning. Furthermore, learners' positive attitudes toward the app supported the overall acceptance of the technology, and the positive activation between app evaluation and learning attitudes underscores the importance of the AR-enriched educational experience. This study not only presents conclusive results on the effectiveness of AR in skill training, but also highlights its potential to address specific challenges in indigenous communities, thus establishing a solid foundation for future applications and developments in the field of education and the training.
