Finite Element Simulation of Laboratory Experiments for Enhanced Learning

工程-化学（53）这个建议回答了几个关于使用模拟实验室实验和学习的问题。通过开发化学工程实验室实验的有限元模型，pi正在调查发现与教程使用的模拟，并检查对学生学习的影响。在辅导模式下，学生执行一套规定的模拟，并对他们观察到的结果给出解释。在发现模式中，学生们使用模拟，生成计算机实验结果，并在实验室前研究中进行分析，类似于他们对待实验室实验结果的方式。学生们在摆弄模型，发现实验系统中发生了什么。FEMLABTM被用于模型开发，允许同时发生的多个物理过程的建模。高年级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的重要性，而不是使用先前开发的模型。在如何以及在何处将有限元建模引入本科课程方面，pi们获得了深刻的见解。此外，他们还在学习计算机模拟是否适合代替动手实验室经验。该项目使用专门为每个实验开发的实验前和实验后测试来评估学生的学习效果。课程评估、学生访谈和调查提供了定性评价。研究结果通过ASEE和FIE会议出版物进行传播。

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.
