Engineering - Chemical (53)This proposal is answering several questions regarding the use of simulated laboratory experiments and learning. By developing finite element models of chemical engineering laboratory experiments, the PIs are investigating discovery versus tutorial use of the simulations and examining the impact on student learning. In the tutorial mode, the students execute a prescribed set of simulations and are given explanations of the results they are observing. In the discovery mode, the students are using the simulations, generating computer-experiment results that they are analyzing in a pre-lab study, similar to how they treat laboratory experimental results. Students are playing with the model and discovering what is happening in the experimental system.FEMLABTM is being used in model development, allowing modeling of multiple physical processes that are occurring simultaneously. Teams of seniors are developing some of the models as part of their senior thesis project. This is allowing the PIs to investigate the importance of students constructing their own simulations, versus using previously developed models. The PIs are gaining insight into how and where to introduce finite element modeling into the undergraduate curriculum. Additionally they are learning whether or not computer simulation is an appropriate replacement for hands on laboratory experience.The project is evaluating enhanced student learning using a pre- and post-lab test developed specifically for each experiment. Course evaluations, interviews and surveys of students is providing qualitative evaluation. Results are being disseminated though ASEE and FIE conference publications.

工程-化学（53）本提案回答了有关使用模拟实验室实验和学习的几个问题。 通过开发化学工程实验室实验的有限元模型，PI正在调查模拟的发现与教程使用，并检查对学生学习的影响。 在教程模式中，学生执行一组规定的模拟，并给出他们观察到的结果的解释。 在发现模式中，学生使用模拟，生成计算机实验结果，他们在实验前研究中分析这些结果，类似于他们处理实验室实验结果的方式。 学生们正在玩模型并发现实验系统中发生的事情。FEMLABTM被用于模型开发，允许对同时发生的多个物理过程进行建模。 大四学生团队正在开发一些模型，作为他们毕业论文项目的一部分。 这使得PI能够调查学生构建自己的模拟与使用先前开发的模型的重要性。 PI正在深入了解如何以及在何处将有限元建模引入本科课程。 此外，他们正在学习计算机模拟是否是一个适当的替代实验室的经验。该项目正在评估加强学生的学习使用前和后的实验室测试，专门为每个实验。 课程评估、访谈和学生调查提供了定性评价。 正在通过ASEE和FIE会议出版物传播成果。
