This study evaluates the impact of augmented reality (AR) on the learning performance of students in an engineering drawing course. An AR-based application called EDINAR was developed to enhance students' understanding of engineering drawing concepts. The study involved 392 first-year engineering students, with 196 in the control group using traditional methods and 196 in the experimental group using EDINAR. One-way ANOVA analysis showed that students using EDINAR outperformed those using traditional methods. Additionally, students in the experimental group provided positive feedback about their learning experience with the AR application. The findings suggest that incorporating AR into engineering education can improve learning performance and enhance the learning experience. AR technology transforms static 2D engineering drawings into interactive 3D visualizations, aiding students in understanding complex geometries and spatial relationships. It also provides real-time feedback, enhances interactivity, and supports the development of essential skills such as digital design and 3D modeling. AR also promotes inclusivity by catering to various learning styles and encourages critical thinking and creative problem-solving. The study recommends integrating AR into engineering education to improve learning outcomes and student engagement.This study evaluates the impact of augmented reality (AR) on the learning performance of students in an engineering drawing course.
