Contribution: The article describes an innovative concept to create authentic application examples for mathematics courses in an engineering degree program in order to illustrate the relevance of mathematics for engineering. Background: It can be difficult and time consuming for mathematics instructors to find and understand authentic applications. Larger projects may be difficult to integrate into an existing course outline. Intended Outcomes: With the help of the new concept, examples can be created that are authentic, that can be embedded in an existing course outline, and that are not too time consuming for the instructor to create. Application Design: The new concept combines two approaches: 1) peer teaching and 2) interaction of different disciplines. In close cooperation with a student from a higher semester who has already successfully completed the course, applications from the student’s study or work context are sought and prepared for successful embedding, and integrated into the course. Findings: An accompanying evaluation study shows that the students in the mathematics courses find the examples created motivating and rate them as authentic and application-oriented.
贡献:文章介绍了一种创新理念,即为工程学位课程中的数学课程创建真实的应用实例,以说明数学与工程的相关性。背景:对于数学教师来说,寻找和理解真实的应用实例既困难又耗时。规模较大的项目可能难以纳入现有的课程大纲。预期成果:在新概念的帮助下,可以创建真实的示例,这些示例可以嵌入到现有的课程大纲中, 而且教师创建这些示例不会太耗时。应用设计:新概念结合了两种方法:1)同伴教学;2)不同学科之间的互动。通过与已成功完成课程的高年级学生密切合作,从该学生的学习或工作背景中寻找和准备成功嵌入的应用程序,并将其整合到课程中。结果:一项附带的评估研究表明,数学课程的学生认为所创建的示例具有激励作用,并认为这些示例真实可信、以应用为导向。

Contribution: This article focuses on the study of Native Hawaiian student experiences in engineering education. Telling these stories illustrates the importance of legitimizing and appreciating different knowledge types in engineering as we move toward a more inclusive and sustainable field. Background: Native Hawaiian engineering students live oppressive realities due to the history of settler colonialism and occupation that attempted to erase their culture and ways of knowing, including in engineering education. This study shows how students overcome these realities to enact their ways of knowing in a field where it is not always respected. Informing the field of ways to promote and respect the different knowledge types of marginalized groups can help to create a more inclusive and sustainable engineering field. Research Question: In what ways do Native Hawaiian students bring their cultural ways of knowing into engineering education? Methodology: We conducted semi-structured interviews with three undergraduate Native Hawaiian students using Manulani Aluli Meyer’s Holographic Epistemology as a theoretical lens to inform the questions and qualitative analysis. The analysis uses a combination of inductive and deductive analyses to create the hologram that Meyer outlines in her work. Findings: The participants found different ways to enact their cultural ways of knowing. We interpret them through the Native Hawaiian values of pono, kuleana, and hō‘ihi. This illustrates how engineering educators, researchers, and programs can legitimize the knowledges of the students by promoting authenticity and reciprocity toward marginalized students and their ways of knowing.
贡献:本文重点研究夏威夷原住民学生在工程学教育中的经历。讲述这些故事说明,在我们迈向一个更具包容性和可持续性的领域时,使工程学中的不同知识类型合法化并对其加以欣赏非常重要。背景:夏威夷原住民工程专业的学生生活在压迫性的现实中,这是因为殖民殖民主义和占领的历史试图抹杀他们的文化和认知方式,包括工程教育中的文化和认知方式。本研究展示了学生们如何克服这些现实,在一个并不总是受到尊重的领域中形成自己的认知方式。让该领域了解如何促进和尊重边缘化群体的不同知识类型,有助于创建一个更具包容性和可持续发展的工程领域。研究问题夏威夷原住民学生是如何将他们的文化认知方式带入工程学教育的?研究方法:我们使用 Manulani Aluli Meyer 的全息认识论作为理论视角,对三名夏威夷土著本科生进行了半结构式访谈,为问题和定性分析提供依据。分析采用归纳和演绎分析相结合的方法,以创建 Meyer 在其著作中概述的全息图。研究结果参与者找到了不同的方式来表达他们的文化认知方式。我们通过夏威夷原住民的 "pono"、"kuleana "和 "hō'ihi "价值观来解释这些方式。这说明了工程教育者、研究人员和项目如何通过促进对边缘化学生及其认知方式的真实性和互惠性,使学生的认知合法化。

While computational thinking arises as an essential skill worldwide, formal primary and secondary education in Latin America rarely incorporates mechanisms to develop it in their curricula. The extent to which students in the region acquire computational thinking skills remains largely unknown. To start addressing this void, this article presents findings from a cross sectional study that characterizes the computational thinking abilities of incoming students at a Chilean university with a strong emphasis on STEM disciplines. Based on more than 500 responses, this study provides evidence of significant inequalities in computational thinking across gender, type of school (private or no), and prior programming knowledge. The discussion offers insights into how these disparities relate to contextual factors of the country, such as a highly socio-economically segregated educational system, public policies focused mainly on technology access, and heavy reliance on voluntary initiatives, to develop computational thinking. The findings can enlighten upcoming research endeavors and formulate strategies to create a more equitable field for students entering STEM degrees in nations facing similar circumstances.
虽然计算思维作为一项基本技能在全球范围内出现,但拉丁美洲的正规中小学教育却很少将培养计算思维的机制纳入课程。该地区的学生在多大程度上掌握了计算思维技能,在很大程度上仍是未知数。为了着手解决这一空白,本文介绍了一项横断面研究的结果,该研究描述了智利一所以 STEM 学科为重点的大学新生的计算思维能力。根据 500 多份回复,本研究提供了不同性别、学校类型(私立或非私立)和先前编程知识在计算思维方面存在显著不平等的证据。讨论深入探讨了这些差异与国家背景因素的关系,如高度社会经济隔离的教育体系、主要关注技术获取的公共政策以及对志愿活动的严重依赖,以发展计算思维。这些研究结果可以为即将开展的研究工作提供启迪,并为面临类似情况的国家制定战略,为进入 STEM 学位学习的学生创造一个更加公平的环境。

The COVID-19 pandemic has introduced challenges to delivering laboratory-based STEM curricula. This study evaluates students’ learning experience in a synchronous team design activity within the laboratory component of an undergraduate Computer Engineering course during the pandemic. Using the EduPad digital platform, students collaborated in small groups to develop a working design for a software simulator. The researchers measured students’ social, cognitive, and teaching presences during the remote team design activities and gathered their feedback on the learning experience. The findings demonstrate that students exhibited high levels of cognitive presence during the remote team design activities, suggesting effective strategies for promoting cognitive presence in synchronous engineering laboratory instruction. This study contributes to the community of inquiry framework and expands the existing repertoire of techniques for enhancing cognitive presence in online synchronous instruction. The implications for further research are also discussed.

Contribution: This concept article shows how the mathematical competencies research framework (MCRF) can guide the design of rubrics to assess engineering mathematics tasks. Practical guidance is given for engineering mathematics educators wanting to create effective rubrics that support student learning and promote academic success. Background: The authors argue that including some rubric-assessed tasks can help students cope better with mathematically challenging concepts. By making explicit the mathematical competencies needed, students may make better use of mathematics concepts outside of mathematics classes. Research Question: What are the design principles for using rubrics to develop mathematical competencies in a way that enables engineering students to voice their values? Methodology: Literature on rubric design was combined with the MCRF and engineering graduate attributes to design rubric principles for tasks involving mathematics competencies. Findings: A general rubric is presented, aligned to six mathematical competencies, with an example of a task and rubric for analyzing ac circuits with complex impedance on GeoGebra. By giving room for students to voice what they value, the rubric design helps to address the challenge of inclusion.

Contribution: Two toolsets for the remote teaching of radio communication laboratory classes: 1) online simulators for individual work of students and 2) a remote access system to laboratory workstations for group work. Initial assumptions and method of implementation of both tools are presented. Background: The COVID-19 pandemic has forced a change in teaching at all levels of education. The specificity of practical classes, such as laboratories, means that the tools used must often be atypical, prepared for a specific type of activity. Intended Outcomes: Hybrid laboratory with tools for remote learning in the form of online simulators and remote access to laboratory workstations, enabling students to achieve the same educational results in the field of radiocommunication as presential classes. Application Design: Online simulators were prepared as Javascript code run in a Web browser as part of a html page, which provide easy integration with various learning platforms and Web servers. The remote access system uses Javascript code for the user interface and a gateway server based on an Apache Web server and FastCGI interface to communicate with C/C++ programs responsible for controlling measuring equipment. Findings: Online simulators have been positively assessed by students during two years of remote learning, but comparison of the grades from remote and presential classes is inconclusive. The obtained grades were comparable in the first year of remote laboratories, but they were worse in the second year than the grades from classroom learning. The system for remote access to the laboratory stands has not yet been evaluated.
贡献:无线电通信实验课远程教学的两个工具集:1) 用于学生个人作业的在线模拟器;2) 用于小组作业的实验室工作站远程访问系统。介绍了这两种工具的初始假设和实施方法。背景:COVID-19 大流行迫使各级教育改变教学方式。实验室等实践性课堂的特殊性意味着所使用的工具必须是为特定类型的活动准备的非典型工具。预期成果:混合实验室配备在线模拟器和远程访问实验室工作站等远程学习工具,使学生能够在无线电通信领域取得与课堂教学相同的教学效果。应用设计:在线模拟器是作为 html 页面的一部分在网络浏览器中运行的 Javascript 代码,可以方便地与各种学习平台和网络服务器集成。远程访问系统的用户界面使用 Javascript 代码,网关服务器基于 Apache 网络服务器和 FastCGI 接口,可与负责控制测量设备的 C/C++ 程序通信。研究结果在两年的远程学习中,在线模拟器得到了学生的积极评价,但远程班和现场班的成绩比较并无定论。第一年的远程实验室成绩相当,但第二年的成绩比课堂学习成绩差。尚未对远程访问实验台的系统进行评估。

Contribution: This article presents an engineering outreach activity that aims to teach K-12 students how to develop a tendon-based soft robotic finger. The primary objectives of this STEM activity are to introduce students to the fundamentals of soft robotics, its interdisciplinary nature, and to offer them a hands-on and engaging learning experience using the project-based- learning approach. Background: Soft robotics, an interdisciplinary field combining chemistry, materials science, and robotics, has the potential to revolutionize the design and development of robots. However, introducing the fundamental concepts of soft robotics to K-12 students can be challenging since traditional robotic activities often require complex programming, technical expertise and expensive equipment and software. Intended Outcomes: Increasing the students’ understanding of soft robotics principles, materials, and polymer processing. Positively impacting students’ perception of engineering as a potential career path by enhancing their attitudes toward STEM. Application Design: Students could develop manually actuated soft robotic fingers within a 45-min workshop by utilizing 3-D printed molds, rapidly curing elastomeric materials, and the basic mold casting method. The outreach activity is intentionally designed to simplify the technology used by eliminating the need for complex programming, and to focus on utilizing novel materials and basic concepts to construct actuating soft robots, providing an effective and engaging STEM activity for K-12 students. Findings: The success/effectiveness of the activity was evaluated in three ways: 1) through direct inspection on the performance of the student-fabricated soft finger during the workshop; 2) through the pre- and post-tests to evaluate the learning outcomes; and 3) by conducting a STEM outreach survey to gather student feedback on the quality of the outreach activity and their attitudes toward STEM. During the workshop activities, the students were able to effectively follow the instructions, construct a tendon-based soft robotic finger, and manually actuate the finger using the tendon. According to the results of pre- and post-tests, the students increased their understanding regarding the principles of soft robotics, materials and polymer processing. Furthermore, the STEM outreach survey of IEEE powered “TryEngineering Portal” revealed that the developed outreach activity enhanced the achievement of pedagogical and quality outcome goals and measures, as well as program targets and objectives.
贡献:本文介绍了一项工程拓展活动,旨在教 K-12 学生如何开发基于肌腱的软机器人手指。这项 STEM 活动的主要目的是向学生介绍软机器人技术的基本原理及其跨学科性质,并采用基于项目的学习方法,为学生提供亲身参与的学习体验。背景:软体机器人学是一个结合了化学、材料科学和机器人学的跨学科领域,有可能为机器人的设计和开发带来革命性的变化。然而,向 K-12 学生介绍软机器人技术的基本概念可能具有挑战性,因为传统的机器人活动通常需要复杂的编程、专业技术知识以及昂贵的设备和软件。预期成果:加深学生对软机器人原理、材料和聚合物加工的理解。通过提高学生对科学、技术和工程学的态度,积极影响他们对工程学作为潜在职业道路的看法。应用设计:学生可以利用 3-D 打印模具、快速固化的弹性材料和基本的铸模方法,在 45 分钟的工作坊内开发出手动驱动的软体机器人手指。推广活动的设计意图是简化所使用的技术,不需要复杂的编程,并侧重于利用新型材料和基本概念来构建致动软机器人,为 K-12 学生提供一个有效且有吸引力的 STEM 活动。研究结果活动的成功/效果通过三种方式进行评估:1) 在工作坊期间直接检查学生制作的软手指的性能;2) 通过前测和后测评估学习成果;3) 通过开展 STEM 外展调查,收集学生对外展活动质量和他们对 STEM 的态度的反馈。在工作坊活动中,学生们能够有效地按照说明,构建一个基于肌腱的软体机器人手指,并利用肌腱手动驱动手指。根据前后测试的结果,学生们加深了对软体机器人原理、材料和聚合物加工的理解。此外,由 IEEE 提供技术支持的 "TryEngineering 门户网站 "的 STEM 外联调查显示,所开发的外联活动促进了教学和质量成果目标和衡量标准以及计划目标和目的的实现。

Contribution: This study used a guided reflective thinking mechanism to improve students’ acceptance of flipped classrooms while promoting the development of students’ will and self-regulated learning strategies to enhance their preclass preparation and participation in classroom activities. Background: Previous research has provided evidence of the impact of flipped classrooms on student learning, but an understanding of the relationship between flipped classrooms, learning strategies, and learning outcomes is limited. Intended Outcome: The learning strategies used by students in the flipped classroom were examined, and the effectiveness of incorporating a guided reflective thinking mechanism into the flipped classroom teaching design of a digital logic (DL) course was evaluated. Application Design: Referring to the strategic learning model, this study integrated the mechanism of guided reflective thinking into the instructional design of a flipped classroom for first-year students in the Department of Electrical Engineering of a junior college in Taiwan. Findings: The results show that the flipped classroom teaching design that guides the reflective thinking mechanism can promote the development of students’ strategies to enhance their attitude, motivation, time management, concentration, self-testing, and solving learning difficulties, thereby improving their performance in DL courses. Furthermore, self-testing strategies are the most important predictor of students’ performance in DL courses.
贡献:本研究采用引导式反思机制,提高学生对翻转课堂的接受程度,同时促进学生意志和自我调节学习策略的发展,加强学生的课前准备和课堂活动参与。研究背景以往的研究已经证明了翻转课堂对学生学习的影响,但对翻转课堂、学习策略和学习效果之间关系的了解还很有限。预期成果:考察学生在翻转课堂中使用的学习策略,评估在数字逻辑(DL)课程的翻转课堂教学设计中加入引导反思机制的效果。应用设计:参照策略学习模式,本研究将引导性反思机制融入台湾某专科学校电子工程系一年级学生的翻转课堂教学设计中。研究结果结果显示,引导反思性思考机制的翻转课堂教学设计能促进学生在态度、动机、时间管理、专注力、自我测试和解决学习困难等方面的策略发展,从而提高他们在DL课程中的表现。此外,自我测试策略是预测学生在通识课程中表现的最重要因素。

A Proposal for an Immersive Scavenger Hunt-Based Serious Game in Higher Education 基于沉浸式寻宝游戏的高等教育严肃游戏提案

Contribution: A successful activity based on the scavenger hunt (SH) game is presented here. Although “serious game” in education now seems synonymous with videogame, the effectiveness of hands-on traditional games to increase student performance that, besides, they also like is defended and proved. The proposal is not focused, as is usual, on a single aspect of the educational environment, but on integrating behavioral and affective aspects into the learning process. Background: The literature analysis shows the predominance of serious games based on videogames in education, perhaps due to the lack of objective evidence concerning the influence of traditional game alternatives, such as SHs, on students’ attitude/learning. This objective evidence is addressed with a proposal to motivate and integrate the students, making them more participative and thus positively affect their learning. Intended Outcomes: The activity increases motivation (behavioral outcome) and socialization (affective outcome), boosting learning (competence outcome); besides, students like the activity. Application Design: The necessity for a different instructional strategy came from the lack of commitment by the students in the first year of Computer Science Engineering. So a game (they are entertaining and powerful tools to increase motivation) that takes the students outside their normal working environment (classroom and laboratory) was designed. The study follows a cross sectional design with experimental and control sets randomly created, and sizes of 106 and 98 students, respectively. Findings: Highly satisfactory and statistically significant results were achieved: their attitude in class and personal study was more active (motivation), new relationships were created (socialization), they obtained better marks (learning) and enjoyed the activity (user experience), even though it was nondigital.
贡献:本文介绍了一个基于寻宝游戏(SH)的成功活动。虽然 "严肃游戏 "在教育领域现在似乎是电子游戏的同义词,但实践证明,传统游戏不仅能提高学生的成绩,还能让他们喜欢。该建议并不像通常那样只关注教育环境的单一方面,而是将行为和情感方面融入学习过程。背景:文献分析表明,以电子游戏为基础的严肃游戏在教育中占主导地位,这可能是由于缺乏有关传统游戏(如 SHs)对学生态度/学习的影响的客观证据。针对这一客观证据,我们提出了一项建议,以激励和融合学生,使他们更积极地参与,从而对他们的学习产生积极影响。预期成果:该活动提高了积极性(行为结果)和社会化(情感结果),促进了学习(能力结果);此外,学生喜欢该活动。应用设计:由于计算机科学工程专业一年级的学生缺乏投入,因此有必要采取不同的教学策略。因此,我们设计了一个游戏(它们是提高学习动机的娱乐性和强有力的工具),将学生带出他们正常的工作环境(教室和实验室)。研究采用横断面设计,实验组和对照组随机产生,学生人数分别为 106 人和 98 人。研究结果取得了非常令人满意且具有统计学意义的结果:他们在课堂和个人学习中的态度更加积极(动机),建立了新的关系(社会化),获得了更好的分数(学习),享受了活动(用户体验),尽管这是非数字化的活动。
