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核心课程，在美国几乎所有土木工程，建筑工程和建筑本科课程中都在教授，这是由于传统讲课方法的缺点，学生在三维（3D）环境中了解结构元素的行为的缺陷。特别是，这种方法通常过多地强调对个别结构成员的分析，从而在提供了稳固，易于遵循和整体方法方面缺乏理解和分析具有大量相互联系元素的复杂结构的方法。 这项研究正在改变结构分析中现有的教学教学法，并填补了目前如何教授结构工程的主要差距。在这个项目中，移动增强现实（AR）用于将现实世界的视图与计算机生成的3D结构模型叠加在一起。这样一来，AR对改善学习和增加学生参与学习过程的潜力正在系统地评估。 基于关于人们如何学习的理论观点，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，以及是否增强了自适应灵活性，这被认为是21世纪成功的工程师至关重要的。该项目的更广泛的影响通过将AR技术纳入较低级别的工程课程，旨在增加追求STEM学位的学生人数，从而超出了其范围。 将AR集成到结构分析教学中的学习模块将在线提供。 网站和在线存储库将包括有关学习目标，实施过程以及在实施教学技术时要考虑的事情的特定详细信息。 开发的软件组件和3D模型将是开源的。
