Immersive learning for structural analysis through mobile augmented reality and the MOLA structural kit

Abstract

Structural analysis is a foundational course in civil and mechanical engineering programs, essential for understanding of how structures respond to various loads. However, traditional teaching methods, constrained by two-dimensional representations, often fall short in conveying three-dimensional structural behavior. In response, this research introduces an innovative augmented reality (AR) application for mobile and tablet devices, designed to provide real-time visual feedback on the structural behavior of physical models. The application enhances students understanding of structural concepts by offering detailed and tangible insights into deflections, reactions, and the development of shear forces and moments within structural elements under applied loads. Users can apply loads in various directions and immediately visualize the corresponding structural responses, fostering a deeper comprehension of complex structural systems. By projecting real-time feedback directly onto physical models, the AR application creates an interactive and immersive learning experience. To evaluate the effectiveness of the application, a case study was conducted with two groups of students: a control group and an experimental group. Pretest and posttest assessments were used to measure learning outcomes, while a comprehensive survey captured students' attitudes and feedback. The results suggest that the AR application consistently enhances learning outcomes across all students, thanks to its interactive environment, real-time visual feedback, and clear presentation of complex concepts. Additionally, the survey revealed strong student acceptance of the AR technology, high levels of engagement, and a positive outlook on its future use in teaching structural analysis.
