Engineering Mechanics courses present unique challenges for engineering students, particularly when dealing with three-dimensional (3D) problems. The ability to visualize where forces act and their directions is fundamental, yet many students struggle with this aspect. Insufficient visualization skills can impede the learning process, making it difficult to grasp additional complex steps in solving 3D problems. This study explores the rationale and implementation of augmented reality and digital 3D models to assist students in overcoming these challenges.
To address these issues, a mobile phone application was developed, incorporating AR technology to enhance students' understanding of 3D Statics problems. Additionally, students were exposed to digital 3D models during lectures focused on 3D problems. The aim is to provide students with more frequent exposure to 3D concepts and to introduce alternative ways of visualizing problems beyond the confines of traditional two-dimensional textbooks. The working hypothesis is that immersing students in 3D scenarios through AR and providing them with interactive 3D models will help them in gaining a more profound understanding of course concepts, particularly those related to 3D problems. Findings and insights from this study contribute to the ongoing efforts in engineering education innovation and provide students with the tools they need to excel in complex 3-D problem-solving scenarios.
