Abstract

Instructors teaching chemical engineering topics have traditionally used graphical methods to explain core concepts and design unit operations. However, with the shift towards online and blended/flexible learning, there is a need to adapt these graphical methods for online use. This paper presents a set of interactive graphs that can be used for fluid flow, separation process, and reaction process unit operations and aims to investigate students' opinions of the interactive graphs and their motivations for using them in their studies. The digital resource developed in the paper is a set of slim single-page applications written in HTML5 & CSS3 with the numerical calculations undertaken in JavaScript (JS). The interactive graphs are embedded into the virtual learning environment (VLE) system Blackboard for two courses, and a paper survey is used to measure students' perceptions towards the interactive graphs and their use of them. The UTAUT2 model is used to analyse the student use of these resources. It is demonstrated that the use of online interactive graphs is popular with the students and the main driving factors are the performance expectancy and the hedonic motivation. Short scaffold questions to help students interact with the graphs are key to their usefulness. Some guidance on the use of interactive graphs is also provided. The interactive graphical resource can be found and used at the Graphical Chemical Engineering Design weblink: https://www.ce.manchester.ac.uk/gced.

化工教学交互式图形资源

教授化学工程主题的教师传统上使用图形方法来解释核心概念和设计单元操作。然而，随着向在线和混合/灵活学习的转变，有必要将这些图形方法调整为在线使用。本文提出了一套可用于流体流动、分离过程和反应过程单元操作的交互图形，旨在调查学生对交互图形的看法以及他们在学习中使用交互图形的动机。本文开发的数字资源是一组用HTML5编写的精简单页应用程序。用JavaScript (JS)进行数值计算的CSS3。交互式图表被嵌入到虚拟学习环境(VLE)系统Blackboard中，用于两门课程，并通过论文调查来衡量学生对交互式图表及其使用的看法。UTAUT2模型用于分析学生对这些资源的使用情况。研究表明，学生普遍使用在线互动图表，其主要驱动因素是表现期望和享乐动机。帮助学生与图表互动的简短框架问题是图表有用性的关键。还提供了一些关于使用交互式图表的指导。交互式图形资源可以在图形化学工程设计网站上找到并使用:https://www.ce.manchester.ac.uk/gced。

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
