The robustness and safety of the built environment is heavily dependent on engineers' understanding of the behavior of solid objects when they are subject to stresses and strains. Mechanics of materials, the study of how solid objects behave when forces are applied to them, is an important foundational course in many engineering disciplines. It is a required course for mechanical, civil, aerospace, environmental, and nuclear engineering majors. Currently, in most engineering undergraduate programs, this subject is taught in a very theoretical way, relying primarily on textbook analyses, illustrations and examples to communicate key concepts. In contrast, hands-on learning has been shown to be highly effective at engaging students in the classroom, leading to better retention of engineering majors, particularly persons underrepresented in engineering such as female students. The proposed project will enhance undergraduate education in mechanics of materials by using hands-on learning techniques. Specifically, 3D-printed artifacts will be created and manipulated by the students. Additionally, a website and an e-textbook will be made available to students and faculty. The hands-on learning approach will be implemented with partner institutions nationally and internationally.Activities to be carried out include the development of practical, accessible instructional materials for facilitating undergraduate learning of concepts in mechanics of materials through the use of 3D-printing technology, incorporation of the instructional materials into the undergraduate curriculum to support the hands-on learning experiences, and dissemination of instructional materials to partner institutions. The project team will also conduct research on the impact of the hands-on learning approach on student learning, self-efficacy, knowledge retention, and satisfaction in the undergraduate level course in mechanics of materials.

建筑环境的稳健性和安全性在很大程度上取决于工程师对固体物体在受到应力和应变时的行为的理解。材料力学研究固体物体在受力时的行为，是许多工程学科的重要基础课程。是机械、土木、航空航天、环境、核工程等专业的必修课程。目前，在大多数工程本科课程中，该课程以非常理论化的方式教授，主要依靠教科书分析、插图和示例来传达关键概念。相比之下，事实证明，实践学习在吸引学生参与课堂方面非常有效，可以更好地保留工程专业的学生，​​特别是女学生等工程专业代表性不足的人。拟议的项目将通过实践学习技术来加强材料力学的本科教育。具体来说，3D 打印的文物将由学生创建和操作。此外，还将向学生和教师提供网站和电子教科书。实践学习方法将与国内外的合作机构一起实施。将开展的活动包括开发实用、易于理解的教学材料，通过使用3D打印技术促进本科生学习材料力学概念，将教学材料纳入本科生课程以支持实践学习经验，以及向合作机构传播教学材料。项目团队还将研究实践学习方法对学生材料力学本科课程学习、自我效能、知识保留和满意度的影响。
