Contribution: This article discusses a research-practice partnership (RPP) where instructors from six undergraduate courses in three universities developed data science modules tailored to the needs of their respective disciplines, academic levels, and pedagogies. Background: STEM disciplines at universities are incorporating data science topics to meet employer demands for data science-savvy graduates. Integrating these topics into regular course materials can benefit students and instructors. However, instructors encounter challenges in integrating data science instruction into their course schedules. Research Questions: How did instructors from multiple engineering and science disciplines working in an RPP integrate data science into their undergraduate courses? Methodology: A multiple case study approach, with each course as a unit of analysis, was used to identify data science topics and integration approaches. Findings: Instructors designed their modules to meet specific course needs, utilizing them as primary or supplementary learning tools based on their course structure and pedagogy. They selected a subset of discipline-agnostic data science topics, such as generating and interpreting visualizations and conducting basic statistical analyses. Although instructors faced challenges due to varying data science skills of their students, they valued the control they had in integrating data science content into their courses. They were uncertain about whether the modules could be adopted for use by other instructors, specifically by those outside of their discipline, but they all believed the approach for developing and integrating data science could be adapted to student needs in different situations.
贡献:本文讨论了一个研究-实践伙伴关系(RPP),其中来自三所大学的六个本科课程的讲师根据各自学科、学术水平和教学法的需要开发了数据科学模块。背景:大学的STEM学科正在纳入数据科学主题,以满足雇主对精通数据科学的毕业生的需求。将这些主题整合到常规课程材料中可以使学生和教师受益。然而,教师在将数据科学教学整合到他们的课程安排中遇到了挑战。研究问题:在RPP中工作的来自多个工程和科学学科的教师如何将数据科学整合到他们的本科课程中?方法:采用多案例研究方法,将每个课程作为一个分析单元,用于确定数据科学主题和集成方法。研究结果:教师根据课程结构和教学方法,设计模块以满足特定的课程需求,将其作为主要或辅助学习工具。他们选择了一个与学科无关的数据科学主题的子集,比如生成和解释可视化以及进行基本的统计分析。尽管由于学生的数据科学技能不同,教师面临着挑战,但他们重视将数据科学内容整合到课程中的控制。他们不确定这些模块是否可以被其他教师,特别是本学科以外的教师采用,但他们都认为,开发和整合数据科学的方法可以适应不同情况下学生的需求。

In recent years, knowledge tracing (KT) within intelligent tutoring systems (ITSs) has seen rapid development. KT aims to assess a student’s knowledge state based on past performance and predict the correctness of the next question. Traditional KT often treats questions with different difficulty levels of the same concept as identical representations, limiting the effectiveness of question embedding. Additionally, higher-order semantic relationships between questions are overlooked. Graph models have been employed in KT to enhance question embedding representation, but they rarely consider the directed relationships between learning interactions. Therefore, this article introduces a novel approach, KT through Enhanced Questions and Directed Learning Interaction Based on multigraph embeddings in ITSs (MGEKT), to address these limitations. One channel enhances question embedding representation by capturing relationships between students, concepts, and questions. This channel defines two meta paths, facilitating the learning of high-order semantic relationships between questions. The other channel constructs a directed graph of learning interactions, leveraging graph attention convolution to illustrate their intricate relationships. A new gating mechanism is proposed to capture long-term dependencies and emphasize critical information when tracing students’ knowledge states. Notably, MGEKT employs reverse knowledge distillation, transferring knowledge from two small models (student models) to a large model (teacher model). This knowledge distillation enhances the model’s generalization performance and improves the perception of crucial information. In comparative evaluations across four datasets, MGEKT outperformed baselines, demonstrating its effectiveness in KT.
近年来,智能辅导系统(ITSs)中的知识追踪(KT)得到了迅速发展。KT的目的是根据学生过去的表现来评估学生的知识状态,并预测下一题的正确性。传统的KT通常将同一概念的不同难度级别的问题视为相同的表示,限制了问题嵌入的有效性。此外,问题之间的高阶语义关系被忽略了。图模型已被应用于KT中以增强问题嵌入表示,但它们很少考虑学习交互之间的直接关系。因此,本文介绍了一种新颖的方法,即基于its中多图嵌入的增强问题和定向学习交互的KT (MGEKT),以解决这些限制。一个通道通过捕获学生、概念和问题之间的关系来增强问题嵌入表示。该通道定义了两个元路径,促进了问题之间高阶语义关系的学习。另一个通道构建了一个学习交互的有向图,利用图注意卷积来说明它们之间复杂的关系。在跟踪学生的知识状态时,提出了一种新的门控机制来捕捉长期依赖关系并强调关键信息。值得注意的是,MGEKT采用逆向知识蒸馏,将知识从两个小模型(学生模型)转移到一个大模型(教师模型)。这种知识蒸馏提高了模型的泛化性能,提高了对关键信息的感知。在四个数据集的比较评估中,MGEKT优于基线,证明了其在KT中的有效性。

Contribution: This article suggests a novel method for diagnosing a learner’s cognitive proficiency using deep neural networks (DNNs) based on her answers to a series of questions. The outcome of the forecast can be used for adaptive assistance. Background: Often a learner spends considerable amounts of time in attempting questions on the concepts she has already mastered. Therefore, it is desirable to appropriately diagnose her cognitive proficiency and select the questions that can help improve preparedness. Research Question: Can the cognitive proficiency of a learner be progressively predicted when she attempts a series of questions? Methodology: A novel approach using DNNs to diagnose the learner’s proficiency after she attempts a set of questions is proposed in this article. Subsequently, to realize the effectiveness of the proposed prediction model, an algorithm is introduced that can select questions of required difficulty based on the predicted proficiency level. An appropriate question sequence can facilitate a learner’s faster attainment of the necessary competency level. Findings: The experimental results indicate that the proposed approach can predict the ability of learners with an accuracy of 91.21%. Moreover, the proposed technique outperforms the existing techniques by 33.19% on an average.

Contribution: Our work focuses on building research capacity in engineering education research (EER). We operationalize enculturation of novice researchers into the EER community by studying temporal changes in the social networks of engineering faculty participating in a mentorship-based training grant. Background: The U.S. National Science Foundation’s Research Initiation in Engineering Formation (RIEF) is a training grant for engineering faculty without prior EER experience who seek to conduct EER. Faculty mentees work with an experienced social science researcher during a funded two-year project. During this time, mentees must undergo a paradigm shift from engineering research to social science, which includes building research skills and becoming enculturated into the EER community. Research Questions: What are the characteristics of RIEF mentees’ professional networks for EER? How do RIEF mentees’ networks change over time, as operationalized by professional interactions, communication about the RIEF project, and collaborations? Methodology: We use social network analysis to investigate the development of EER professional networks of RIEF mentees and their interactions with other community members during the first year of their research initiation training. Findings: Overall, mentees’ professional networks for EER increased (i.e., reported more connections) after one year. However, when mentors had limited prior connections to the EER community, their mentees’ social networks for EER are isolated compared to mentees whose mentors have a higher number of connections to community members. Our findings have implications for mentored training programs, suggesting that well-connected mentors are best placed to enculturate mentees into a research community.
贡献:我们的工作重点是建设工程教育研究(EER)的研究能力。我们通过研究参与师徒培训资助的工程学院的社会网络的时间变化,将新研究人员融入EER社区的文化化操作化。背景:美国国家科学基金会的工程形成研究启动(RIEF)是一项培训补助金,用于没有先前EER经验的寻求进行EER的工程教师。在一个为期两年的资助项目中,学院学员与一位经验丰富的社会科学研究员一起工作。在此期间,学员必须经历从工程研究到社会科学的范式转变,其中包括建立研究技能和融入EER社区。研究问题:RIEF学员的EER专业网络有什么特点?通过专业互动、RIEF项目沟通和合作,RIEF学员的网络如何随着时间的推移而变化?方法:我们使用社会网络分析来调查RIEF学员的EER专业网络的发展,以及他们在研究启动培训的第一年与其他社区成员的互动。研究结果:总体而言,一年后学员的EER专业网络增加了(即报告了更多的联系)。然而,与导师与社区成员有更多联系的徒弟相比,导师与社区成员有更多联系的徒弟的社会网络是孤立的。我们的研究结果对有指导的培训项目有启示,表明关系良好的导师最适合将学员融入研究社区。

Contribution: This study synthesizes insights into the thematic focuses and linguistic attributes that resonate most in engineering faculty collaborations aimed at fostering entrepreneurial mindsets (EMs). It provides a roadmap for educators and institutions to effectively communicate and encourage entrepreneurial thinking in engineering. Background: Amid the heightened emphasis on entrepreneurial thinking in engineering education, understanding the factors that resonate with faculty is pivotal for informing curriculum development, aligning with global trends, and optimizing the preparedness of engineering graduates. Research Questions: 1) What elements of the EM are most frequently emphasized by faculty in their shared educational content? 2) What aspects of the EM resonate most with academic faculty? and 3) How do these relations differ in the electrical or computer engineering disciplines compared to other engineering fields? Methodology: A comprehensive analysis of educational resources shared by faculty on EM was conducted. The study used text analytics to assess engagement metrics, such as views, shares, favorites, and downloads. The data were analyzed using Stata. Findings: Faculty engagement strongly resonates with the three core components of the EM: Curiosity, Connections, and Creating Value, often emphasized in their shared educational content. Specifically, the “Creating Value” component emerged as the most significant across most engagement measures, with nuanced variations in the electrical and computer engineering disciplines.

Contribution: This article provides an examination of changes in first-year engineering students’ perceptions of the role of an engineer after completing the Engineers Without Borders Challenge. Background: Essential pre- and post-comparisons missing in existing studies on the Challenge are provided, as well as comparison to other first-year project types across two universities. Research Question: Do students who participate in service-learning versus traditional project-based learning gain different understandings of the role of an engineer? Methodology: This work implements the questionnaire variant of convergent mixed methods design. A survey containing a mix of Likert-scale, open-ended short answer, and closed card sorting questions was administered to students enrolled in first-year engineering (FYE) courses across two institutions. Limitations of this work include potential bias due to the pre/post survey design and participant course self-selection. Findings: Students’ perceptions of the roles of engineers did not significantly differ by project type. However, changes in their perceptions of technical skills as important to the role of engineers did indicate the beginning of a transition from discipline level thinking to process level thinking. Additionally, course learning objectives influenced students’ perceptions of the role of engineers—with an increase in awareness of the importance of problem solving, communication, design process, and teamwork and a decreasing sense of importance of items missing from course objectives, such as creativity and helping people. Engineers’ professional responsibility to diversity, equity, and inclusion were absent from both the course syllabi and student perceptions of the role of an engineer.
贡献:本文探讨了工程专业一年级学生在完成 "工程师无国界挑战赛 "后对工程师角色认知的变化。背景:本文提供了关于挑战赛的现有研究中所缺少的基本前后对比,以及与两所大学其他一年级项目类型的对比。研究问题:参加服务学习和传统项目学习的学生对工程师角色的理解是否不同?研究方法:这项工作采用了趋同混合方法设计的问卷变体。我们对两所院校的一年级工程学(FYE)课程学生进行了问卷调查,调查内容包括李克特量表、开放式简答题和封闭式卡片分类题。这项工作的局限性包括前/后调查设计和参与者课程自选可能造成的偏差。调查结果:学生对工程师角色的认知并没有因项目类型的不同而产生显著差异。然而,他们对技术技能对工程师角色的重要性的看法发生了变化,这表明他们开始从学科层面的思维向过程层面的思维过渡。此外,课程学习目标也影响了学生对工程师角色的认识--对解决问题、沟通、设计过程和团队合作重要性的认识有所提高,而对课程目标中缺失的项目(如创造力和助人为乐)重要性的认识有所下降。在课程大纲和学生对工程师角色的认识中,都没有提到工程师对多样性、公平和包容的职业责任。

Understanding mathematics is essential for learning many concepts in engineering. Conceptual learning of engineering requires students to successfully connect abstract and concrete concepts to achieve a cohesive understanding of the content, and doing so goes beyond memorizing facts and applying formulas. Educators can observe that conceptual learning “has happened” once a student is able to successfully explain the concept, use the concept, and create new knowledge from the learned concept [1]. Moreover, a student’s ability to understand, both qualitatively and quantitatively, the mathematical equations and computations that describe various engineering processes and phenomena is necessary for the conceptual learning of many courses in engineering.
理解数学对于学习工程学的许多概念至关重要。工程学的概念学习要求学生成功地将抽象概念和具体概念联系起来,以达到对所学内容的连贯理解。一旦学生能够成功地解释概念、使用概念,并从所学概念中创造出新的知识,教育者就可以观察到概念学习 "已经发生"[1]。此外,学生在定性和定量方面理解描述各种工程过程和现象的数学方程和计算的能力,对于工程学中许多课程的概念学习都是必要的。

Contributions: An adoption framework to include generative artificial intelligence (GenAI) in the university curriculum. It identifies and highlights the role of different stakeholders (university management, students, staff, etc.) during the adoption process. It also proposes an objective approach based upon an evaluation matrix to assess the success and outcome of the GenAI adoption. Background: Universities worldwide are debating and struggling with the adoption of GenAI in their curriculum. GenAI has impacted our perspective on traditional methods of academic integrity and the scholarship of teaching, learning, and research. Both the faculty and students are unsure about the approach in the absence of clear guidelines through the administration and regulators. This requires an established framework to define a process and articulate the roles and responsibilities of each stakeholder involved. Research Questions: Whether the academic ecosystem requires a methodology to adopt GenAI into its curriculum? A systematic approach for the academic staff to ensure the students’ learning outcomes are met with the adoption of GenAI. How to measure and communicate the adoption of GenAI in the university setup? Methodology: The methodology employed in this study focuses on examining the university education system and assessing the opportunities and challenges related to incorporating GenAI in teaching and learning. Additionally, it identifies a gap and the absence of a comprehensive framework that obstructs the effective integration of GenAI within the academic environment. Findings: The literature survey results indicate the limited or no adoption of GenAI by the university, which further reflects the dilemma in the minds of different stakeholders. For the successful adoption of GenAI, a standard framework is proposed 1) for effective redesign of the course curriculum; 2) for enabling staff and students; and 3) to define an evaluation matrix to measure the effectiveness and success of the adoption process.
贡献:将生成式人工智能(GenAI)纳入大学课程的采用框架。它确定并强调了不同利益相关者(大学管理层、学生、教职员工等)在采用过程中的作用。它还提出了一种基于评估矩阵的客观方法,用于评估 GenAI 应用的成功和成果。背景:全世界的大学都在为在课程中采用 GenAI 而争论不休。GenAI 影响了我们对传统学术诚信方法以及教学、学习和研究学术的看法。由于缺乏行政部门和监管机构的明确指导,教师和学生对这种方法都不确定。这就需要有一个既定的框架来确定一个过程,并阐明每个利益相关者的角色和责任。研究问题:学术生态系统是否需要将 GenAI 纳入课程的方法?为学术人员提供一种系统方法,以确保采用 GenAI 后学生的学习成果得到满足。如何衡量和宣传大学采用 GenAI 的情况?研究方法:本研究采用的方法侧重于考察大学教育系统,并评估与将 GenAI 纳入教学相关的机遇和挑战。此外,本研究还确定了阻碍将 GenAI 有效融入学术环境的差距和综合框架的缺失。调查结果:文献调查结果表明,大学对 GenAI 的采用有限或根本没有采用,这进一步反映了不同利益相关者心中的困境。为了成功采用 GenAI,提出了一个标准框架:1)有效地重新设计课程设置;2)为教职员工和学生赋能;3)定义一个评估矩阵,以衡量采用过程的有效性和成功率。
