Virtual Online Tensile Strength Testing Simulation

该项目是1）开发一个开源的，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，动手拉伸测试设备与在线模拟的成本和学习成果; 3）通过混合学习机会为学生创造密切的行业联系;和4）通过教师发展传播模拟。该项目正在测试一个假设，即在线学习提高了成果，同时降低了教学成本。它弥补了现有的拉伸测试软件产品之间的差距，要么太简单，要么太复杂。该项目使用一个全面的学生学习评估，沿着准实验研究设计，以确定模拟器对学生和他们的教师相比，传统的学习没有模拟器的影响。虽然项目中的概念验证属于常见的工程学习活动，但研究适用于其他工程领域和其他学科。该项目包括其他机构可以很容易地以很少的费用采用的活动。正在开发的开放源码工具将分发给教授材料课程的本科生和高中教师，从而增加采用的可能性。访问虚拟实验室将允许资源有限的团体获得所需的学习成果，而无需对拉伸强度测试设备进行大量资本投资。

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.
