Exploring Studio-Based Learning in Chemical Engineering Education

该项目建立在以前开发的称为ChemProV(化学过程可视化)的脚手架软件环境之上。ChemProV为化学工程专业的学生提供动态生成的反馈，说明他们不断演变的过程流程图和方程式组的句法和语义正确性，指导他们找到正确的解决方案。先前的评估表明，ChemProV在解决问题的准确性、显著更多的任务时间以及将训练转移到无支架的解决问题的情况下，在统计上具有显著优势。为了扩大其影响，该项目将ChemProV与以工作室为基础的课程方法相结合，在该方法中，学生使用ChemProV来构建物质和能量平衡问题的解决方案，并将他们的解决方案呈现给他们的同龄人和教师，以供批判性审查和讨论。该项目将ChemProV整合到一个在线同行审评环境中，从而使同行审评能够完全在线进行。10个新机构的化学工程讲师将在他们的入门材料/能量平衡课程中采用ChemProV和基于工作室的方法，并参加关于它们对学生学习、态度和保持的影响的严格的准实验评估。通过该项目支持的培训、合作和研究，该项目建立了一个化学工程教育工作者社区，他们致力于应用、提炼和改进ChemProV和基于工作室的方法。

This project builds on a previously developed scaffolded software environment called ChemProV (Chemical Process Visualizer). ChemProV presents chemical engineering students with dynamically-generated feedback on the syntactic and semantic correctness of their evolving process flow diagrams and sets of equations, guiding them toward correct solutions. Prior evaluations show that ChemProV promotes a statistically significant advantage in problem-solving accuracy, significantly more time on task, and a robust transfer-of-training to an unscaffolded problem-solving situation. In order to expand its impact, this project integrates ChemProV with a studio-based curricular approach in which students use ChemProV to construct solutions to material and energy balance problems, and present their solutions to their peers and instructor for critical review and discussion. The project integrates ChemProV into an online peer review environment, thus enabling the peer reviews to be performed completely online. Chemical engineering instructors at 10 new institutions will adopt ChemProV and the studio-based approach in their gateway material/energy balance courses, and participate in a rigorous quasi-experimental evaluation of their impact on student learning, attitudes, and retention. Through the training, collaboration, and research supported by this project, the project builds a community of chemical engineering educators who are committed to applying, refining, and improving ChemProV and the studio-based approach.
