Enhancement of Student Learning in Experimental Design using Virtual Laboratories

工程-化学（53）本CCLI第二阶段项目致力于寻找更有效的方法将实验设计整合到工程课程中。该项目建立在基于化学气相沉积第一性原理数值模型的原型虚拟实验室的基础上，为学生提供了模型的选择输出，从而使他们能够专注于实践工程师典型的完整交互式实验设计过程。原型正在扩展，以包括过程经济约束和统计、反射工具和真实的可变性工具。一个工业生物反应器过程的虚拟实验室也正在开发中，这些虚拟实验室正在与物理实验室一起使用。该项目通过在3个本科、2个研究生、大约10个社区学院和大约10个高中项目中实施来促进教学、学习和教师专业知识。评估包括项目结束后的调查，通过虚拟实验室收集的数据，以及“大声思考”协议，以定性和定量地研究学生使用虚拟实验室的学习方式。该项目的研究结果在顶级工程教育会议和期刊上以及通过网站进行传播。

Engineering - Chemical (53)This CCLI Phase Two Project is addressing the need for more effective methods to integrate experimental design into the engineering curriculum. The project is building on a prototype virtual laboratory based on a first-principles numerical model of chemical vapor deposition that provides students access to a selected output of the model and thus allows them to concentrate on the complete interactive experimental design process typical of practicing engineers. The prototype is being expanded to include process economic constraints and statistics, reflective tools, and authentic variability tools. A virtual laboratory of an industrial bioreactor process is also being developed and these virtual laboratories are being used in conjunction with physical laboratories. This project is promoting teaching, learning, and faculty expertise through implementation in 3 undergraduate, 2 graduate, approximately 10 community college and approximately 10 high school programs. The assessment includes end-of-project surveys, data collected via the virtual laboratories, and "think aloud" protocols to qualitatively and quantitatively study the ways students learn using virtual laboratories. The findings from this project are being disseminated at top engineering education conferences and journals, as well as through a website.
