This paper describes a project with common equipment that was adapted and offered to both an undergraduate and a graduate-level course with learning outcomes tailored specifically to each group of students. This project is an immersive, multi-disciplinary engineering design activity with a focus on materials, solid mechanics, and instrumentation. The activity incorporates aspects of fundamental engineering theory, virtual predictive simulation, as well as physical testing and data collection. All of this was done in the context of a material selection and failure analysis of a piece of furniture (cantilever chair) which is a simplistic and recognizable device by the students. The project focusses on structural analysis of the chair under a variety of loading conditions, coupled with a virtual simulation model using Finite Element Analysis (FEA). FEA is utilized to identify critical regions of the structure which are prone to failure. The complexity, constraints, and provided resources of the model varied, depending on the specific implementation of the course. Finally, a physical test apparatus was constructed and used to generate experimental responses that the students were able to use to calibrate their predictive model and theoretical hand calculations. This activity was created initially for in-person instruction but was adapted for remote delivery during the pandemic. Both qualitative and quantitative data collected from 2nd year and graduate students indicated that the activity was effective in improving several forms of knowledge acquisition. This paper will discuss in detail how a common project platform was adapted for the two academic levels with evidence of its efficacy
本文描述了一个使用通用设备的项目,该项目适用于本科和研究生水平的课程,并为每个学生群体量身定制了学习成果。这个项目是一个沉浸式的、多学科的工程设计活动,重点是材料、固体力学和仪器。该活动结合了基础工程理论、虚拟预测仿真以及物理测试和数据收集等方面。所有这些都是在对一件家具(悬臂椅)进行材料选择和失效分析的背景下完成的,这是一种简单而可识别的设备。该项目侧重于在各种载荷条件下对椅子进行结构分析,并结合使用有限元分析(FEA)的虚拟仿真模型。利用有限元分析来识别结构中容易发生破坏的关键区域。模型的复杂性、约束条件和提供的资源因课程的具体实现而异。最后,构建了一个物理测试装置,并用于生成实验响应,学生可以使用该实验响应来校准他们的预测模型和理论手工计算。这项活动最初是为现场教学而设立的,但在大流行期间进行了调整,用于远程授课。从二年级学生和研究生中收集的定性和定量数据表明,该活动有效地改善了几种形式的知识获取。本文将详细讨论一个共同的项目平台是如何适应两个学术水平的,并证明其有效性

Persistent mistakes in learning basic circuit analysis 学习基本电路分析时的持续性错误
Pub Date : 2022-11-01 DOI: 10.24908/pceea.vi.15974

Basic circuit analysis is a core course in most of the undergraduate engineering programs and is the prerequisite course for many other courses in the undergraduate electrical engineering program. Students enter into engineering schools with varying knowledge of the concepts of basic circuit analysis depending on whether they come from high school, CEGEP, or a technical college, etc. Many students from all engineering majors struggle to learn the concepts taught in these courses which creates challenges for both faculty members and students in courses when for which basic circuit analysis is a pre-requisite course. There is more research done in understanding the conceptual knowledge of physics of electricity and electric (and electronic) components and improving the instruction of basic circuit analysis concepts, but not enough work is done to understand the mistakes undergraduate electrical engineering students continue to make course after course. For this study, the authors look at the persistent problems in learning circuit analysis techniques by looking at students’ use of these techniques in three core courses in electrical engineering program namely electronics 1, electronics 2 and electromagnetic waves and guiding structures. Students’ responses to exam questions that specifically expected students to use these concepts are analyzed. The objective of the study was to analyze whether the understanding of the application of circuit analysis techniques get better as students continue to use these concepts in more courses and applications, or the problems persist. Results show that the students persistently make mistakes in applying KVL and KCL equations, nodal analysis, superposition theorem, voltage divider, and mesh analysis. Additionally, the results reveal that students persistently make mistakes in questions that involve the concepts of load and no load, open circuit, series components, parallel components, voltage drop across the current source, and voltage gain. It is noted that the mistakes made by students do not get much better as they continue taking more courses. The results of this study are important from many aspects. They are helpful to understand the continuing struggles of students and so are helpful to design pedagogy and assessment in a way that these concepts can be well explained. Thorough understanding of the concepts in a course that is as important as basic circuit analysis is important to achieve many engineering education goals including student retention, motivation, innovation, and inclusion.
基础电路分析是大多数本科工程专业的核心课程,也是本科电气工程专业许多其他课程的前提课程。进入工程学校的学生对基本电路分析概念的了解各不相同,这取决于他们是来自高中、CEGEP还是技术学院等。许多来自所有工程专业的学生都在努力学习这些课程中教授的概念,这给课程的教师和学生带来了挑战,因为基础电路分析是一门必修课程。在理解电学和电气(和电子)元件物理的概念知识以及改进基本电路分析概念的教学方面做了更多的研究,但在理解电气工程本科学生不断犯的错误方面做的工作还不够。在这项研究中,作者通过观察学生在电气工程专业的三门核心课程,即电子学1、电子学2和电磁波与导向结构中使用这些技术来研究学习电路分析技术的持续问题。分析了学生对考试问题的反应,这些问题特别要求学生使用这些概念。本研究的目的是分析随着学生在更多的课程和应用中继续使用这些概念,他们对电路分析技术应用的理解是否会越来越好,或者问题仍然存在。结果表明,学生在KVL和KCL方程、节点分析、叠加定理、分压器、网格分析等方面的应用存在较大错误。此外,结果还显示,学生在涉及负载和空载、开路、串联元件、并联元件、电流源电压降和电压增益等概念的问题上经常犯错误。值得注意的是,学生犯的错误并没有随着他们继续学习更多的课程而变得更好。本研究结果具有多方面的重要意义。它们有助于理解学生的持续挣扎,因此有助于以一种可以很好地解释这些概念的方式设计教学和评估。透彻理解课程中的概念与基本电路分析一样重要,这对于实现许多工程教育目标至关重要,包括留住学生、激励学生、创新和包容。

This paper introduces a methodology to investigate the impact of utilizing multilayered peer learning pedagogical strategies to integrate the Canadian Engineering Grand Challenges into a large first-year engineering design course. The Canadian Engineering Grand Challenges (CEGC) evolved from the seventeen UN sustainable development goals (UNSDG). The CEGC focus on achieving access to safe water; resilient infrastructure; sustainable energy, industry, and cities; and inclusive STEM education. The incorporation of the CEGC into higher education can be viewed as a tool to empower students to understand the significance of engineering in society with respect to the achievement of the UNSDG. Consequently, their inclusion in the first-year engineering education curriculum serves to engage students with urgent and complex societal problems and the socio-contextual impact of engineering decisions and designs. Peer learning has regularly been applied as an active learning strategy, often with smaller class sizes. A multilayered peer learning strategy was implemented to engage students with the CEGC in a large class of ~1100 students. This strategy is reviewed with respect to delivery logistics and observed efficacy.
本文介绍了一种方法来研究利用多层同伴学习教学策略将加拿大工程大挑战整合到大型一年级工程设计课程中的影响。加拿大工程大挑战(CEGC)是从17个联合国可持续发展目标(UNSDG)演变而来的。ceg的重点是实现获得安全用水;有弹性的基础设施;可持续能源、工业和城市;以及包容性STEM教育。在高等教育中纳入cec可以被视为一种工具,使学生能够理解工程在实现联合国可持续发展目标方面的社会意义。因此,将它们纳入第一年的工程教育课程有助于让学生参与紧迫而复杂的社会问题以及工程决策和设计的社会背景影响。同侪学习经常被用作一种主动学习策略,通常采用较小的班级规模。在一个约1100名学生的大班中,采用多层同侪学习策略使学生参与CEGC。这一战略是审查有关交付物流和观察到的有效性。

Facilitating Cross & Beyond Course Project-Based Software Engineering Learning Experiences 促进跨课程和超越课程项目为基础的软件工程学习经验
Pub Date : 2022-11-01 DOI: 10.24908/pceea.vi.15838
Timothy Maciag
Throughout each academic semester, software engineering students are often provided with opportunities to explore open-ended project-based activities. Within the confines of specific courses, many of these explorations have resulted in interesting and impactful, partially or fully engineered software solutions. However, after student-developed solutions are explored, tested, and delivered within a classroom setting it has been the author’s experience that they often don’t progress beyond the course in which students explored and created them in. The results of this are missed opportunities for innovation as well as missed opportunities for further creative and collaborative explorations. This work-in-progress explores the following question: what could a model, process, and/or framework look like that would enable software engineering educators to create a learning environment that facilitates continued exploration, collaboration, and iteration of project-based student work beyond individual courses? This paper will describe an exploratory hybrid framework called ORhiDeCy that the author has designed and has been exploring in his courses over the last several years. This paper describes ORhiDeCy, an example of its successful use in the author’s software engineering teaching practice, collaborator and student feedback, and the author’s reflections and ideas for continued explorations.
在每个学期中,软件工程专业的学生经常有机会探索开放式的基于项目的活动。在特定课程的范围内,许多这些探索产生了有趣和有影响力的,部分或完全工程化的软件解决方案。然而,在学生开发的解决方案被探索、测试并在课堂环境中交付之后,作者的经验是,这些解决方案通常不会超出学生探索和创造它们的课程。这样做的结果是失去了创新的机会,也失去了进一步创新和合作探索的机会。这个正在进行的工作探讨了以下问题:一个模型、过程和/或框架是什么样子的,它将使软件工程教育者能够创建一个学习环境,以促进在个别课程之外的基于项目的学生工作的持续探索、协作和迭代?本文将描述一个名为ORhiDeCy的探索性混合框架,该框架是作者在过去几年的课程中设计并一直在探索的。本文描述了ORhiDeCy,这是作者在软件工程教学实践中成功使用的一个例子,合作者和学生的反馈,以及作者对继续探索的思考和想法。

Strong leadership has been required during the COVID-19 pandemic to protect public health and ease the adaptation to living “remotely.” This study explores whether and how COVID-19 has impacted engineers’ leadership identities through the lens of Relational Leadership Theory. From qualitative survey responses, leadership identity was found to be both strengthened and weakened, as well as both changed and not changed by Relational, Structural, and Personal Agency factors. The quantitative data showed that women, racialized people, and internationally trained engineers were more likely to be affected by the pandemic in some way than male, white, or Canadian trained engineers. Implications for engineering educators include the importance of teaching students about structural barriers to leadership and ways to support the leadership development of students who are returning to in-person learning with transformed leadership identities.
在2019冠状病毒病大流行期间,需要强有力的领导来保护公众健康,并缓解对“远程”生活的适应。本研究通过关系领导理论探讨了COVID-19是否以及如何影响工程师的领导身份。从定性调查的回应中,我们发现领导认同在关系因素、结构因素和个人代理因素的影响下既有加强的一面,也有削弱的一面,既有改变的一面,也有不改变的一面。定量数据显示,女性、种族化的人和受过国际培训的工程师比男性、白人或加拿大培训的工程师更有可能在某种程度上受到大流行的影响。对工程教育工作者的启示包括,向学生讲授领导力的结构性障碍的重要性,以及支持领导力发展的方法,这些学生正在以转变的领导力身份回到亲自学习中。

At the Department of Electrical and Computer Engineering and the School of Biomedical Engineering at the University of British Columbia (UBC) a system of providing and refining time estimates for student completion of homework assignments has been introduced in two integrated second-year Engineering and Math courses. Particular attention has been given to individual homework questions. In this paper findings to date are presented after two offerings of the courses in which this system was implemented. By using student feedback from the first offering to adjust instructor time estimates, instructors were able to obtain time estimates accurate to within 5 minutes of student reported averages for 77% of ELEC211 and 64% of BMEG 220 questions. Student perception of the usefulness of time estimates was generally positive, ranging from 35% to 64% of students reporting the initiative to be either ‘useful’ or ‘very useful’ over 3 years of data. Examples drawn from both courses will be discussed to demonstrate how the collected data is being used to identify areas of further improvement to assignment questions and course structure.
英属哥伦比亚大学(UBC)电气与计算机工程系和生物医学工程学院在二年级的工程和数学综合课程中引入了一个系统,为学生完成家庭作业提供和改进时间估计。对个别家庭作业问题给予了特别的关注。在这篇论文中,迄今为止的发现是在两个课程中提出的,其中这个系统是实施的。通过使用学生的反馈来调整教师的时间估计,教师能够获得准确的时间估计,在77%的ELEC211和64%的BMEG 220问题中,学生报告的平均时间在5分钟内。学生对时间估计有用性的看法总体上是积极的,在3年的数据中,35%到64%的学生报告该倡议“有用”或“非常有用”。我们将讨论从这两门课程中抽取的例子,以演示如何使用收集到的数据来确定作业问题和课程结构需要进一步改进的领域。

There are many challenges related to the implementation of project-based learning (PBL) in the engineering curriculum. The amount of work required by instructors to design well-posed projects is a barrier to the broad adoption of PBL. On the other hand, poorly designed PBL activities often cause frustration among students, create extra work for instructors and students alike, and generally detract from the intended learning outcomes. In this paper we introduce a unique co-curricular program that supports instructors in the creation of high-quality and high-impact PBL activities. The program is innovative as it involves and benefits multiple stakeholders including students employed through the program, faculty, industry, and the engineering curriculum. The ongoing efforts to improve the program are also described.    
在工程课程中实施基于项目的学习(PBL)存在许多挑战。教师需要大量的工作来设计良好的项目,这是PBL广泛采用的一个障碍。另一方面,设计不良的PBL活动往往会使学生感到沮丧,给教师和学生都带来额外的工作,并且通常会损害预期的学习成果。在本文中,我们介绍了一个独特的课外计划,支持教师在创建高质量和高影响力的PBL活动。该计划是创新的,因为它涉及并受益于多个利益相关者,包括通过该计划雇用的学生,教师,行业和工程课程。还描述了正在进行的改进程序的努力。

Systems Theory Framework for Embedding Lifelong Learning Holistically in Undergraduate Engineering Education 在本科工程教育中全面嵌入终身学习的系统理论框架
Pub Date : 2022-11-01 DOI: 10.24908/pceea.vi.15885

The new educational imperative is to empower students to manage their own learning in a variety of contexts throughout their lifetimes. This is particularly true for fields that rely on fast-changing technology, like engineering. As such, lifelong learning is gaining increased recognition. This paper describes a holistic framework for addressing lifelong learning in undergraduate engineering programs. The authors draw on existing literature to support this novel framework which consists of: 1) course design that intentionally aligns lifelong learning outcomes, teaching strategies, and assessment methods, 2) experiential learning opportunities that scaffold students’ development of lifelong learning in authentic and relevant ways, 3) instructor commitment to their own lifelong learning, and 4) conceptualization of lifelong learning as an overarching graduate attribute that can be incorporated alongside the others.
新的教育要求是使学生能够在一生中在各种环境中管理自己的学习。对于那些依赖于快速变化的技术的领域来说尤其如此,比如工程学。因此,终身学习正获得越来越多的认可。本文描述了一个解决本科工程项目终身学习的整体框架。作者利用现有文献来支持这一新的框架,其中包括:1)课程设计有意地将终身学习成果、教学策略和评估方法结合起来;2)体验式学习机会,以真实和相关的方式支撑学生终身学习的发展;3)教师对自己终身学习的承诺;4)终身学习的概念化,作为一个总体的毕业生属性,可以与其他属性结合起来。

Following the United Nations Declaration on the Rights of Indigenous Peoples and other guiding documents, engineering schools in Canada have begun the work of Indigenous reconciliation by helping students develop competencies relevant to engineering study, research, and practice. In our School, a curricular project has been implemented in the undergraduate program: a key element is the Indigenous Community Consultation Project (ICCP) delivered through a required communication course. Through a case study approach, students learn intercultural communication skills in the specific context of preparing to work with Indigenous communities in Canada. In developing and delivering the ICCP, course instructors are also empowered to take part in relevant professional development initiatives and to grow their pedagogical practices. We are now studying the impact of the ICCP on students’ learning and plan to share results in future publications.
根据《联合国土著人民权利宣言》和其他指导性文件,加拿大的工程学校通过帮助学生培养与工程学习、研究和实践相关的能力,开始了土著和解的工作。在我们学院,在本科课程中实施了一个课程项目:其中一个关键要素是通过必修的沟通课程提供土著社区咨询项目(ICCP)。通过案例研究方法,学生在准备与加拿大土著社区合作的特定背景下学习跨文化沟通技巧。在制定和提供ICCP的过程中,课程教师也被授权参与相关的专业发展倡议,并增加他们的教学实践。我们现在正在研究ICCP对学生学习的影响,并计划在未来的出版物中分享结果。

Assessing Ethical Sensitivity Development in Undergraduate Engineering Students 评估工科本科生的伦理敏感性发展
Pub Date : 2022-11-01 DOI: 10.24908/pceea.vi.15923

Canadian engineers are expected to uphold high ethical standards as part of their responsibility to the profession and society. This expectation is echoed in the Canadian Engineering Accreditation Board (CEAB) graduate attributes and in the Ritual of the Calling of an Engineer [1], [2]. Part of upholding high ethical standards as an engineer involves the essential skill of being able to detect and identify ethical issues. This refers to one’s Ethical Sensitivity (ES), which is often overlooked in Engineering Ethics Education (EEE) currently. EEE in North America primarily focuses on the action plans and justifications developed to address presented ethical dilemmas, not on how to identify ethical dilemmas. This then leads to the question, are students’ ES skills being developed over the course of their undergraduate career? While there is some existing research on ethical decision-making and the factors that influence it, there is markedly less research on ES, less on ES assessment, and even less on ES assessment in engineering students. Additionally, the majority of ES assessment tools currently used are either not designed to specifically assess ES, are not designed for engineering, and/or cue the participant in some way to the ethical dilemmas presented, which could misrepresent the participant’s actual ES abilities.This research will investigate current literature on ethical sensitivity and will also describe a research method to assess ES development in undergraduate engineering students. The focus of this paper will be on a pilot study currently in progress along with the next steps for this research. These results can provide insight to educators, ideally resulting in more effective teaching practices, and ultimately creating more ethically conscious engineering graduates.
加拿大工程师被期望保持高道德标准,作为他们对专业和社会责任的一部分。这种期望在加拿大工程认证委员会(CEAB)的毕业生属性和工程师召唤仪式中得到了回应[1],[2]。作为一名工程师,保持高道德标准的一部分包括能够发现和识别道德问题的基本技能。这是指一个人的伦理敏感性(ES),这是目前工程伦理教育(EEE)中经常被忽视的。北美的EEE主要关注为解决出现的道德困境而制定的行动计划和理由,而不是如何识别道德困境。这就引出了一个问题,学生的ES技能是否在他们的本科生涯中得到了发展?虽然已有一些关于道德决策及其影响因素的研究,但对道德决策的研究明显较少,对道德决策评估的研究较少,对工科学生道德决策评估的研究更少。此外,目前使用的大多数ES评估工具要么不是为专门评估ES而设计的,要么不是为工程设计的,或者以某种方式提示参与者所呈现的道德困境,这可能会歪曲参与者的实际ES能力。本研究将调查当前关于伦理敏感性的文献,并将描述一种评估本科工程学生ES发展的研究方法。本文的重点将放在目前正在进行的试点研究以及该研究的下一步。这些结果可以为教育工作者提供见解,理想地导致更有效的教学实践,并最终创造更多具有道德意识的工程毕业生。
