实验室经验为工科本科生提供了主要来自实践活动的知识。一些大学可能缺乏必要的资金来使用工程教育中使用的一些设备；因此可以建造低成本的替代方案。低成本的实验室体验应该按照以下要求设计：它们应该提供评估相关学习成果的框架，它们应该提供理论信息的可视化演示，它们应该是用户友好的，它们应该提供一致的结果。本文详细介绍了一种低成本的弹簧质量阻尼器装置的构造和实验室练习，用于动态建模或振动过程中的系统辨识。本文还介绍了用于系统识别的方法、评估框架，以及通过作者的网站和YouTube上的视频访问项目材料的信息。对这一实验室体验的初步测试结果表明，实验室材料和设备在促进学生学习方面是有效的。
Laboratory experiences provide undergraduate engineering students with knowledge that comes primarily from hands-on activity. Some universities may lack necessary funds to utilize some of the equipment used in engineering education; so low-cost alternatives can be constructed. Lowcost laboratory experiences should be designed according to the following requirements: they should provide a framework to assess the achievement of associated learning outcomes, they should provide a visual demonstration of theoretical information, they should be user friendly, and they should provide consistent results. This paper details the construction of a low-cost spring mass damper apparatus and laboratory exercise, for system identification in a dynamic modeling or vibrations course. This paper also describes the methods used for system identification, an assessment framework, and information for accessing the project materials via the author’s website and videos on YouTube. The results of an initial test of this laboratory experience with a small student population demonstrate the effectiveness of the lab materials and apparatus in facilitating student learning.
