Structural Analysis is an introductory core course that is taught in almost all civil engineering, architectural engineering, and construction undergraduate programs across the U.S. Previous research unveils students' deficits in understanding the behavior of structural elements in a three-dimensional (3D) context due to the shortcomings of traditional lecturing approaches. In particular, such approaches often put too much emphasis on the analysis of individual structural members, thereby falling short in providing a solid, easy-to-follow, and holistic approach to comprehending and analyzing complex structures with a large number of interconnected elements. This research is transforming existing teaching pedagogy in structural analysis and filling a major gap in how structural engineering is currently taught to the nation's future workforce in U.S. institutions. In this project, mobile augmented reality (AR) is used to superimpose views of the real world with computer generated 3D models of structures under load. In doing so, the potential of AR for improving learning and increasing student engagement in the learning process is being systematically assessed. Building upon theoretical perspectives on how people learn, this project is also examining if pedagogy involving AR creates an effective learning environment for students, as well as if it enhances adaptive flexibility, which is deemed to be essential to be a successful engineer in the 21st Century. The broader impacts of this project extend beyond its confines through outreach activities such as integrating AR technology into lower-level engineering courses that aim to increase the number of ethnically-diverse students pursuing STEM degrees. The learning modules integrating AR into teaching of structural analysis will be made available online. A website and online repository are to include specific details about the learning objectives, implementation procedures, and instructor reflections on things to consider while implementing the teaching techniques. The developed software components and 3D models will be open source.

结构分析是一门入门性核心课程，几乎在美国所有土木工程、建筑工程和建筑本科课程中都会教授该课程。之前的研究揭示了由于传统教学方法的缺陷，学生在理解三维 (3D) 环境中结构元素的行为方面存在缺陷。特别是，此类方法往往过于强调单个结构构件的分析，从而无法提供可靠、易于遵循且整体的方法来理解和分析具有大量互连元素的复杂结构。 这项研究正在改变现有的结构分析教学法，并填补了目前美国机构向未来劳动力教授结构工程的重大空白。在该项目中，移动增强现实 (AR) 用于将现实世界的视图与计算机生成的负载结构 3D 模型叠加。在此过程中，我们正在系统地评估 AR 在改善学习和提高学生参与学习过程中的潜力。 基于人们如何学习的理论视角，该项目还在研究涉及 AR 的教学法是否为学生创造了有效的学习环境，以及它是否增强了适应性灵活性，这被认为是成为 21 世纪成功工程师的关键。该项目的更广泛影响超出了其范围，通过外展活动，例如将 AR 技术整合到较低级别的工程课程中，旨在增加攻读 STEM 学位的多种族学生的数量。 将 AR 融入结构分析教学的学习模块将在线提供。 网站和在线存储库应包含有关学习目标、实施程序以及教师对实施教学技术时要考虑的事项的反思的具体细节。 开发的软件组件和 3D 模型将开源。
