Virtual Labs, Real Data, Including Biological Materials for Statics and Mechanics of Materials

工程-机械(56)正在进行概念验证，以开发基于网络的材料静力学和力学实验模块，这是为机械、土木和生物工程专业学生开设的两门基础课程。目前正在开发两个模块。第一个模块是一个非常初步的实验，使用苏打罐中的压力作为薄壁压力容器理论的演示。该项目的第二个单元和主要活动侧重于工程材料和生物材料的扭转。该模块以基于网络的说明为特色，将样品准备过程和进行实际实验的过程的音频、文本和视频结合在一起。此外，本模块还提供真实测试的数据，其中包括学生下载和分析的生物材料数据，作为他们实验室报告的一部分。该项目的目标之一是开发一个服务于各种教育需求的基于网络的实验室。因此，这第二个单元是在与包括两年制社区大学在内的几所学校的同事协商后开发的。一旦开发，该模块将在康奈尔大学和其他学校实施和评估。基于网络的实验室的方法将基于网络的指令与真实数据结合在一起，成为跨越许多工程学科的模型。这也是使基于网络的教学更加活跃的一步，除了提供过程的可视化和解释外，还要求学生进行大量的分析。该项目将对康奈尔大学和其他机构上材料静力学和力学课程的大量学生产生直接影响。如果成功，该项目将导致全面部署建议，并探索实验室材料的商业化。如果将实验室材料商业化，可能会影响更多的工程和技术专业学生，因为除了参与该项目的机构外，许多机构都教授材料的静力学和力学。关键词：基于网络的实验模块、基于网络的静力学教学、基于网络的材料力学教学

Engineering - Mechanical (56) A proof-of-concept is being undertaken for the development of web-based laboratory modules for statics and mechanics of materials, two foundational courses for Mechanical, Civil, and Biological Engineering students. Two modules are being developed. The first module is a very preliminary experiment using the pressure in a soda can as a demonstration of thin-walled pressure vessel theory. The second module and principal activity of the project focus on the torsion of both engineered and biological materials. This module features web-based instructions which combines audio, text and video of the sample preparation process and the process of conducting the actual experiments. Furthermore, this module also provides data from real tests, which includes data from biological materials that the students download and analyze as part of their laboratory reports. One goal of the project is to develop a web-based laboratory that serves a variety of educational needs. As a consequence, this second module is being developed in consultation with colleagues from several schools including two-year community college. Once developed, the module will be implemented and evaluated at Cornell and at the other schools. The approach to web-based laboratories, which combines web-based instructions with real data, serves as a model across many engineering disciplines. It is also a step towards making web-based instruction more active by requiring substantial analysis by the student in addition to providing visualization and explanation of the processes. The project will have immediate impact on the large number of students who are taking the statics and mechanics of materials classes at Cornell and at other institutions. If successful, the project will lead to a full deployment proposal and to exploration of the commercialization of the laboratory materials. If commercialized, the laboratory materials could impact a larger number of engineering and technology students, since statics and mechanics of materials are taught at many institutions other than the ones involved in the project.
