This study examined whether the introduction of the concept of defense-in-depth, an approach used to achieve process safety, could allow university students and staff to propose improved, multilayered measures of the risk reduction for incidents that can occur in chemistry laboratories. A 10-minute seminar on defense-in-depth was conducted with university members. The participants completed questionnaires before and after the seminar. The collected data were analyzed with statistical methods and quantitative text analysis. After the seminar, the participants were able to propose a significantly larger number of safety measures per person for given incident scenarios than they could before the seminar. Furthermore, although before the seminar, participants’ attention was primarily focused on items that are easily imagined from the incident scenario, they proposed safety measures across all levels of defense-in-depth after the seminar. These findings are indisputable evidence that the seminar enabled participants to propose multilayered risk-reduction strategies. The results provide valuable insight into the development of more effective safety education programs and practices of risk reduction that can be implemented in chemistry laboratories.</div><div><strong>Tweetable abstract</strong></div><div>A short seminar on defense-in-depth enabled university students propose more multilayered and effective measures for risk reduction in chemistry laboratories.</div></div>","PeriodicalId":48509,"journal":{"name":"Education for Chemical Engineers","volume":"54 ","pages":"Article 100497"},"PeriodicalIF":2.3,"publicationDate":"2025-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145747649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The approach integrates Vygotsky's sociointeractionist theory, emphasizing social interaction and mediation within the Zone of Proximal Development, with active learning strategies proven effective in engineering education. An educational card game focused on polymerization mechanisms was developed and coupled with a hands-on demonstrative synthesis of hydrogels. This dual approach combines the motivational aspects of games, e.g., immediate feedback, progressive challenges, and collaborative gameplay, while providing tangible evidence of theoretical principles through practical experimentation. Students worked in small teams to achieve optimal card combinations while exploring complex polymer reaction engineering concepts, followed by laboratory practice, allowing real-time observation and analysis of typical chain-growth reaction processes.

The design integrated Kolb’s Experiential Learning Theory and constructivism within a learning-oriented assessment perspective. A mixed-methods approach combined a 10-item Likert questionnaire with open-ended reflections from the same cohort (N = 46). Quantitative analyses reported descriptive tendencies, Spearman inter-item associations (primary), and internal consistency while qualitative data underwent thematic analysis. Perceptions of the assessment were uniformly positive, and the scale showed excellent reliability (Cronbach’s α = 0.952). Inter-item associations formed a coherent pattern consistent with a single experiential construct rather than isolated features. Qualitatively, 28 students’ comments converged on six themes which were knowledge and understanding (hands-on activity clarifies concepts), collaboration (peer dialogue and mutual correction), affective engagement (enjoyable, low-stakes), skill development (communication, confidence), autonomy and creativity (decision-making, problem solving), and learning-oriented element. Together, these findings indicated that concrete experience, structured peer interaction, and immediate feedback jointly support sense-making and participation. Overall, the tea-making SLE operated as assessment-as-learning, eliciting the very performances it sought to cultivate while maintaining a psychologically safe environment. Minor instrument refinements are recommended to enhance sensitivity at the top end and surface transfer more explicitly across future cohorts. The approach is inexpensive, scalable, and theoretically aligned, offering a practical template for embedding authentic, experiential and constructivist assessment in unit-operations teaching.</div></div>","PeriodicalId":48509,"journal":{"name":"Education for Chemical Engineers","volume":"54 ","pages":"Article 100495"},"PeriodicalIF":2.3,"publicationDate":"2025-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145579831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Participants completed comprehensive pre-lab and post-lab assessments that included quantitative surveys and qualitative feedback. Results revealed substantial gains in students' confidence, procedural competence, and conceptual understanding. Specifically, over 90 % of students reported high levels of confidence in aseptic techniques, cell thawing, cryopreservation, and cell counting. The quantitative analysis also demonstrated that the virtual lab significantly enhanced students’ understanding of the principles underlying cell culture and media preparation. Performing virtual lab enabled them to acquire the knowledge and skills necessary to perform, control, and monitor experiments in a physical laboratory setting. Although the virtual lab also contributed to improved understanding in certain areas such as the environmental conditions within a biosafety cabinet these gains were not statistically significant.

The process begins by identifying support needs, making curricular adjustments, co-designing assistive tools, and implementing them when necessary. In cases where specific adaptations are required to support laboratory participation or study-related tasks, low-cost and replicable devices are developed (crucial in the context of public education in emerging or developing countries) using Arduino programming and 3D printing. The process addressed individual learning needs while also fostering broader institutional improvements in inclusive teaching practices.

{"title":"Integrating artificial‑intelligence assistance into chemical process control education","authors":"Zuyi Huang","doi":"10.1016/j.ece.2025.10.002","DOIUrl":"10.1016/j.ece.2025.10.002","url":null,"abstract":"<div><div>Chemical process control is traditionally one of the most mathematically demanding courses in the chemical engineering curriculum. Students need to master ordinary differential equations (ODEs), Laplace transforms, transfer functions and proportional‑integral‑derivative (PID) controller design. At Villanova University we developed a pilot project to integrate artificial‑intelligence assistance throughout the process‑control pipeline. Three modules were created: (1) Python coding for ODE simulation, (2) Laplace and inverse Laplace transforms with transfer‑function parameter estimation, and (3) PID controller tuning. For each module, pre-class videos and handouts introduced theoretical concepts and demonstrated example code. Students reviewed these materials before class, and class time was used primarily for answering questions and clarifying concepts. Most project work was completed independently outside of class. Students were instructed to ask a large‑language‑model chatbot (ChatGPT) to explain equations, generate and debug Python code, and interpret the physical meaning of models. Pre‑class handouts and videos prepared students for both in-class and independent practice, and anonymous surveys measured learning impact and students’ overall experience. Fifty-nine students completed all three modules and responded to a 15-question survey, which included 13 multiple-choice rating questions and 2 open-ended questions. The rating questions were grouped into categories measuring students’ confidence in Python coding, understanding of ODE modeling and process control concepts, ability to use AI tools effectively, and perceived applicability of the skills to real-world problems. Responses were scored on a five-point scale, where a rating of 5 indicated the most positive feedback. Statistical analysis showed mean ratings ranging from 3.28 to 4.36, with the highest confidence gain reported in the category assessing the ability to apply the learned skills to real-world problems. Qualitative comments reveal that students valued the novelty of using AI tools but desired clearer instructions and more coding guidance. This study demonstrates a fully integrated approach to AI-assisted education in chemical process control, spanning ODE modeling, Laplace transform, transfer functions, and controller tuning within a single coherent framework. By combining Python-based coding in Google Colab with structured AI interaction strategies, the work bridges theoretical concepts and practical applications across the entire modeling–control pipeline. This project offers an example for AI-based control and engineering education studies.</div></div>","PeriodicalId":48509,"journal":{"name":"Education for Chemical Engineers","volume":"54 ","pages":"Article 100492"},"PeriodicalIF":2.3,"publicationDate":"2025-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145475473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By leveraging online course resources and implementing a flipped classroom approach, the model seeks to enhance student agency, transforming traditional classrooms into dynamic interactive arenas for teachers, engineers, and learners. Centered on scenario-based project cases, the approach fosters core professional skills and is reinforced by a comprehensive assessment system applied across all instructional stages. The curriculum is deconstructed into six major modules and 251 course knowledge points, which are utilized to construct a knowledge graph. These knowledge points are categorized into conceptual knowledge points (99), skill-based knowledge points (110), and cognitive knowledge points (90), serving as the basis for tracking and evaluating teaching effectiveness. This system enables personalized monitoring of learning progression and quantifies the entire learning trajectory.
