The project is 1) developing an open source, virtual, online tensile testing laboratory simulation; 2) conducting research to compare the costs and learning outcomes for using on-site, hands-on tensile testing equipment versus an online simulation; 3) creating close industry ties through blended learning opportunities for students; and 4) disseminating the simulation via faculty development. The project is testing the hypothesis that online learning improves outcomes and simultaneously reduces instructional costs. It is bridging a gap between existing tensile testing software products that are either too simple or too complex. The project is using a comprehensive assessment of student learning, along with a quasi-experimental research design, to determine the impact of the simulator on students and their instructors compared to traditional learning without the simulator. Although the proof of concept in the project pertains to a common engineering learning activity, the research is applicable to other engineering areas and other disciplines. The project includes activities that can be easily adopted by other institutions with little cost. The open-source tool being developed will be disseminated to undergraduate and high school faculty members who teach strength of materials courses, thus increasing the likelihood of adoption. Access to a virtual lab will allow groups with limited resources to attain desired learning outcomes without large capital investments for tensile strength testing equipment.

该项目是1)开发一个开源、虚拟的在线拉伸测试实验室模拟；2)进行研究，比较使用现场实际拉伸测试设备与在线模拟的成本和学习结果；3)通过为学生提供混合学习机会建立紧密的行业联系；以及4)通过教师发展传播模拟。该项目正在检验这一假设，即在线学习可以改善结果，同时降低教学成本。它正在弥合现有拉伸测试软件产品之间的差距，这些软件产品要么过于简单，要么过于复杂。该项目使用对学生学习的综合评估，以及准实验研究设计，以确定与没有模拟器的传统学习相比，模拟器对学生及其教师的影响。虽然项目中的概念验证属于一种常见的工程学习活动，但该研究也适用于其他工程领域和其他学科。该项目包括一些活动，这些活动可以很容易地被其他机构采用，成本很低。正在开发的开源工具将传播给教授材料强度课程的本科生和高中教职员工，从而增加采用的可能性。使用虚拟实验室将使资源有限的团队在不需要对抗拉强度测试设备进行大量资本投资的情况下获得所需的学习结果。
