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

工程-机械（56）基于网络的静力学和材料力学实验模块的概念验证正在进行中，这是机械、土木和生物工程专业学生的两门基础课程。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，使用汽水罐中的压力作为薄壁压力容器理论的演示。第二个模块和项目的主要活动侧重于工程和生物材料的扭转。该模块的特点是基于网络的指令，结合了音频，文本和视频的样品制备过程和进行实际实验的过程。此外，该模块还提供真实测试的数据，其中包括来自生物材料的数据，学生可以下载并分析这些数据，作为实验室报告的一部分。该项目的目标之一是开发一个基于网络的实验室，以满足各种教育需求。因此，第二个模块正在与包括两年制社区学院在内的几所学校的同事协商开发。一旦开发完成，该模块将在康奈尔大学和其他学校实施和评估。基于网络的实验室方法，将基于网络的指令与真实数据相结合，作为跨许多工程学科的模型。除了提供可视化和过程解释外，它还要求学生进行大量分析，从而使基于网络的教学更加活跃。该项目将对大量在康奈尔大学和其他机构学习静力学和材料力学课程的学生产生直接影响。如果成功，该项目将导致全面部署建议，并探索商业化的实验室材料。如果商业化，实验室材料可能会影响更多的工程和技术专业的学生，因为材料的静力学和力学是在许多机构教授的，而不是在参与项目的机构。关键词：网络实验模块，静力学网络教学，材料力学网络教学

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.
