This project aims to serve the national interest by improving how architectural and civil engineering students learn abstract engineering concepts and develop knowledge about how to design buildings, bridges, and other large-scale structures. It seeks to build the Architecture, Engineering, and Construction industry sector by supporting a workforce with increased proficiency in structural design. The educational enhancements to be developed and tested in this Level 1 Engaged Student Learning project rely on immersive group learning activities designed to help students to comprehend fundamental engineering concepts and to visualize solutions to complex structural design problems without reliance on mathematical formulas. The pedagogy, technology, and methodology for designing these types of learning experiences could be applied to other curricula, suggesting that this research has significant potential for broader impacts on undergraduate STEM education in a range of disciplines that rely on physical or computer models to help visualize abstract concepts and solve complex problems. Project goals include plans to build on recent advances in three technologies – Spatial Augmented Reality, Tangible User Interfaces, and Natural Language Processing – to develop a projection-based immersive learning environment with interactive physical models and a natural language interface to help support learning. The project design relies on Collaborative Learning, an educational approach th
