摘要

2019冠状病毒病大流行给本科课程的实验部分的操作和促进主动学习带来了重大挑战,只有很短的时间可以实施替代教学方法。在这项工作中,开发了一个用于远程操作和评估可替换的台式换热器的低成本平台,为学生提供了一个在无法进入实验室设备时观察换热器瞬态和稳态行为的机会。每个工作台的新材料成本约为5 000加元。物理设备的操作为学生提供了观察非理想行为和比较各种传热相关性的机会,这在过程模拟器中可能看不到。开发的平台实现了一个Arduino微控制器,用于低成本的过程控制。在返回校园学习后,设备无缝地插入到现有课程中,与之前存在的实验室实验相比,提供了一个更稳定的系统。大多数学习成果是在远程和室内实验中观察到的,并强调了远程操作面临的挑战。远程完成实验的学生与室内完成实验的学生成绩无统计学差异。

Low-cost heat exchanger benches for remote operation

The COVID-19 pandemic created significant challenges in operating the lab component of undergraduate courses and promoting active learning, with only a short time available to implement alternative teaching methods. In this work a low-cost platform for distance operation and assessment of replaceable bench-scale heat exchangers was developed to provide students an opportunity to observe the transient and steady-state behavior of heat exchangers while unable to access lab facilities. Each workbench had a new material cost of approximately C$5 000. Operation of physical equipment provided students the opportunity to observe non-ideal behavior and compare various heat transfer correlations which may not be seen in process simulators. The developed platform implemented an Arduino microcontroller for low-cost process control. Equipment was seamlessly slotted in to the existing course upon the return to on-campus learning and provided a more stable system when compared to previously existing lab experiments. Most learning outcomes were observed in remote and in-lab experiments and challenges faced in remote operation are highlighted. No statistically significant difference was observed in student performance between students completing lab experiments remotely and students completing experiments in-lab.

期刊介绍: Education for Chemical Engineers was launched in 2006 with a remit to publisheducation research papers, resource reviews and teaching and learning notes. ECE is targeted at chemical engineering academics and educators, discussing the ongoingchanges and development in chemical engineering education. This international title publishes papers from around the world, creating a global network of chemical engineering academics. Papers demonstrating how educational research results can be applied to chemical engineering education are particularly welcome, as are the accounts of research work that brings new perspectives to established principles, highlighting unsolved problems or indicating direction for future research relevant to chemical engineering education. Core topic areas: -Assessment- Accreditation- Curriculum development and transformation- Design- Diversity- Distance education-- E-learning Entrepreneurship programs- Industry-academic linkages- Benchmarking- Lifelong learning- Multidisciplinary programs- Outreach from kindergarten to high school programs- Student recruitment and retention and transition programs- New technology- Problem-based learning- Social responsibility and professionalism- Teamwork- Web-based learning
