Exploring Serious Play in the Engineering Classroom to Support the "Joyification" of Education and Learning
Authors: Maciag Tim
Published: December 2024

Serious play has the potential to enable creative and advanced learning experiences while incorporating enjoyable/fun learning activities. This can be highly relevant in engineering education, where the gravity and responsibility associated with the profession can be daunting for both students and educators. This study explores the integration of serious play in the software engineering classroom. The exploration aimed to transform classroom dynamics and find more effective ways to connect students with the gravity of the engineering discipline while enhancing student satisfaction and understanding during the learning process and adding fun elements. Two distinct serious play activities were designed and evaluated. The first was inspired by Stanford's D.School's Gift Giving Project and the Lego Serious Play activity, while the second drew inspiration from popular board games like Monopoly and Trivial Pursuit. Both serious play activities were evaluated in early-year undergraduate and graduate software engineering classrooms, where qualitative feedback was gathered to measure student perception toward the joyification of their education and learning. This paper describes the designed serious play activities, discusses student evaluation results, and discusses opportunities for continual improvement.

Authors: Farrokh Shouka , Evelyn-Piprawala Mehmooda , Endale Naomi , Wolf Jessica , McLeod Kaylin , Cheung Karen , D'Entremont Agnes
Published: December 2024

Evaluating outreach efforts can include measuring changes in factors such as Engineering or STEM Identity. STEM/Engineering Identity involves an internal feeling of belonging and recognition from others (e.g., family, teachers). Strong STEM/Engineering Identity is associated with entering STEM careers. This pilot study examines one large outreach program to determine: are there changes in STEM or Engineering Identity after a weeklong day-camp? Are there differences associated with gender, age, race, or intersectional identities, and/or having role models or parents in engineering? Elementary campers (grades 4-7), high school campers and volunteer Junior Instructors (both grades 8-12) were surveyed pre- and post-camp. We measured STEM Identity for elementary campers and Engineering Identity for teenagers through validated survey measures. Teenagers were also asked about role models, having parents in engineering, and career goals. While there were small increases in STEM/Engineering Identity, participants generally started with high STEM/Engineering Identity and frequently had role models in engineering.

Published: December 2024

Biomedical engineering (BME) has one of the highest proportion of women students of any discipline in Canada, and at University of British Columbia (UBC). Anecdotal evidence, based on instructors' interactions with senior students, suggests that women and gender-minority students in UBC’s BME program might leave engineering post-graduation, at higher numbers and for careers in health sciences/medicine. Our aim was to examine reasons for choosing BME, changes in career goals degree and post-graduation career paths of alumni. We conducted 21 semi-structured interviews with current/past BME students and identified five themes related to pursuing/continuing in BME: Positive and Negative Family Influences; Safety Net of a BME Degree; Dual Identities as Engineer and Physician; Perceived Need for High Grade Averages as a Barrier; and Social Environment as a Factor in Choosing Disciplines. These themes are interconnected, and a combination of themes is needed to explain why students choose to pursue/continue in BME.
Re-Engineering the Culture: Perspectives of the Feminine-Identifying and Queer Engineering Student
Authors: McDougall Matthew , Charbonneau Marie
Published: December 2024

The inclusion of queer and feminine-identifying students in science, technology, engineering, and mathematics (STEM) is an issue which expresses ample discussion, yet little action. Students belonging to these groups face barriers relating to identity of group and self, peer exclusion and intolerance, and trivialization of their work. This paper reviews the literature of 21st century United States and Canada on this topic, expanding into closely related topics, including underrepresentation, cultural cis-heteronormativity, essentialism, and marginalization. It reveals the firsthand experiences of students affected by the cultures of their engineering faculties, as well as their attempts to either persevere through the repression of identity or remain sidelined by their environment. This narrative literature review provides solutions based on research, including EDI curriculum implementation, supportive student clubs, queered survey methods and moderated language. These solutions offer direction for future research efforts and provide methods on scales small or large to improve inclusion in engineering education.
A Self-Directed Module To Empower Engineering Students To Engage with Equity, Diversity, Inclusion, and Indigeniety
Authors: Vaez Ghaemi Roza , Potvin Gabriel , Trajano Heather
Published: December 2024

Background: Engineering faces significant EDI-related challenges. Despite the professional value of EDI being well established, related content in engineering curricula remains limited, and its valuation by students remains mixed. Purpose: Greater integration of EDI in engineering programs can increase engagement with, and valuation of, these concepts. A new student-driven EDI module deployed in both technical and non-technical courses was developed and assessed. Approach: Students engaged with self-selected EDI-related activity, and submitted reflections which were analyzed to assess their emotional, behavioural and cognitive engagement with the material, and level of EDI competence. Outcomes: Results suggest a notable increase in engagement and appreciation of EDI topics following the activity, suggesting that the module is effective at increasing the valuation of EDI in engineering. Conclusions: Given this flexibility and self-directed nature, the activity can be assigned multiple times. It may therefore be strategically integrated throughout the curriculum.
The Impact of the Inherent Language Complexity on Academic Performance: Using Data Analytic Approach to Profile Diverse Student Learning
Authors: Shi Yunsong , Liu Qin , Norval Graeme , Chan Ariel
Published: December 2024

The study examines how language complexity in engineering courses affects students' academic performance to create a more inclusive learning environment. While math is crucial, language proficiency also impacts success, often overlooked. We aim to assess language complexity in chemical engineering courses, proposing a methodology to gauge curriculum progression from basic knowledge to problem-solving and design. Chemical engineering courses typically start with core concepts and advance to practical application. Our goal is to establish a method reflecting this progression and identify areas for improvement. Using natural language processing (NLP), we analyze course materials and final exams, defining features like word frequency and syntactic complexity. Performance data from a decade and 1100 graduates validate our analysis, showing increased language complexity in higher-level courses. International students initially outperform citizens, but this diminishes in advanced courses. Our study pioneers a framework for assessing course language difficulty, aiding curriculum evaluation and student support. By integrating NLP and data analytics, it identifies diverse learning challenges, enabling more inclusive education. Future research should expand to include more courses and disciplines, enhancing educational equity and effectiveness.

Faculty members identified challenges and successes in redesigning courses, emphasizing the importance of faculty development and student-centered programming. It contributes to the scholarship of teaching and learning by documenting the faculty perspective on block model implementation, informing best practices for engineering educators. The findings highlight the potential of the block model to foster active learning communities and suggest areas for future refinement.
Accelerating Awareness: Hidden Equity, Diversity, and Inclusion Learning Outcomes within an Immersive Classroom Activity
Authors: Jiang Albert , Williams Jensen , Mattucci Stephen
Published: December 2024

This work addresses the challenge of meaningfully introducing engineering students to equity, diversity, and inclusion (EDI) principles. Traditionally, tertiary education introduces these concepts through online modules and/or workshops, often ‘down-selling’ them compared to technical courses. This paper proposes a more impactful experiential approach targeting the affective learning domain. In collaboration with the Centre for Student Wellness, instructors designed a lesson integrating EDI principles into an interactive car simulation game. Students form teams and customize their cars based on survey responses, with rewards and penalties reflecting real-world inequalities. For instance, certain car colors or gender characteristics may result in penalties, mirroring observed racism and gender biases in STEM fields. This innovative approach aims to foster critical thinking about the role of personal privilege in decision-making, offering a dynamic learning experience beyond conventional methods.

Authors: Medlock Laura , Robb Kevin , Hameed Sania , Banh Jennifer , Kilkenny Dawn
Published: December 2024

The University of Toronto Faculty of Applied Science and Engineering offers strong support for undergraduate students to participate in experiential opportunities outside of the classroom, in particular summer research. The Undergraduate Summer Research Program (USRP) was created to promote development of ‘success skills’ that enhance students’ research experience and build community through weekly sessions led by faculty experts. The experience culminates with research outcome dissemination at the annual Undergraduate Engineering Research Day. Since 2020, the USRP has evolved to in-person and seen a steady increase in student participation. Anonymous participant survey data indicates greatest appeal for students having just completed their second year of study. Engagement has been observed to change post-COVID as specific in-person departmental activities have resumed. Students participating regularly find positive support for their research experience and demonstrate success in dissemination, indicating sessions are helpful and interesting. There is also appreciation for peer-community from across the engineering disciplines. Four summers of USRP execution allow for shared recommendations in creating such a program.

Published: December 2024

Engineering students have varied vocational motivations and aspirations. Clarity regarding these factors, how they can be nurtured, and how they can impact attrition from the profession can help foster retention and diversification. A survey was deployed in 2023 at six Canadian schools, garnering about 2500 responses. Approximately 45 questions examined demographics, motivations for choosing engineering, engineering identity, personality characteristics, career aspirations, and influencing factors. We focus on three research questions in this study: 1) to what extent do students self-identify as engineers (in training), 2) do students have preferences concerning the types of organizations they aspire to work within, and 3) do students have preferences concerning the types of work (or employment trajectories) they aspire to pursue. Responses were examined across gender, year of study, and institution, and were characterized using descriptive statistics, significance testing, and ANOVAs. Initial results provide a rich picture of student career interests, varying by demographics.

Authors: Abelló Juan , Strunk Randi , Maw Sean
Published: December 2024

Incoming first-year engineering students at the University of Saskatchewan completed a survey about their motivation to study engineering. Ninety-one student responses were analyzed within the expectancy value theory framework, including interactions with demographics. Statistical analysis showed intrinsic value (interest/enjoyment) was more important in choosing engineering than attainment (identity) and utility values in the decision to study engineering. There were statistically significant differences in some motivation scores across gender and regional background. Wanting to study engineering because of job prospects and the respect earned by having an engineering degree was rated higher for female than male students, while wanting to study engineering to learn how things work was more prevalent in students from Saskatchewan than students from abroad.

Authors: Lusina Paul , Moghtader Bruce , Haji Faraji Parnia
Published: December 2024

This article describes how critical service learning pedagogy is applied to a 4th year Capstone design course in electrical & computer engineering. We create a series of modules based on the Social Implications Lab toolkit developed at UBC. The modules’ goals are: to develop students’ reflective and collaborative decision-making abilities in the context of their Capstone project, and to provide instruction and assessment of the non-technical CEAB graduate attributes for the purpose of accreditation. Student data indicates that students recognize the importance of the individual reflection – team collaboration process. They describe ways that the modules have supported their solution to topics related to the non-technical CEAB graduate attributes. The student feedback identifies a number of ways that the module design could be made more effective including better connection to the Capstone course deliverables, more support in developing reflection and collaboration techniques, and more emphasis on relating projects to systemic social / environmental issues.
Przemysł w strukturze funkcjonalnej małych miast województwa małopolskiego
Authors: Brzosko-Sermak Agnieszka , Kwiatek-Sołtys Agnieszka , Gałązka Natalia
Published: December 2024

W dobie tercjalizacji i gospodarki postindustrialnej rodzą się pytania nie tylko o efektywność rozwoju małych ośrodków miejskich wyłącznie na bazie funkcji usługowych, lecz także o potrzebę i możliwości reindustrializacji miast. Klasyczne podejście do badań funkcjonalnych, wykorzystujące struktury pracujących i analizę zarejestrowanych podmiotów gospodarczych, pokazują, że w województwie małopolskim w latach 1973–2023 i w XXI w. struktura funkcjonalna miast ulegała zasadniczej zmianie. Celem pracy jest diagnoza współczesnej roli przemysłu w strukturze funkcjonalnej małych miast województwa małopolskie‑ go, przedstawienie zmian w zakresie struktury pracujących oraz działalności gospodarczej oraz wskazanie tendencji rozwojowych funkcji przemysłowej w kontekście obowiązujących strategii rozwoju małych miast. W części metodycznej wykorzystano tradycyjną metodę wyznaczania struktury funkcjonalnej, opracowaną przez M. Jerczyńskiego (1977). Omówiono również obecną strukturę funkcjonalną, opierając się na danych dotyczących liczby podmiotów gospodarczych zarejestrowanych w rejestrze REGON w podziale na działy i sekcje. Ważną częścią prowadzonych badań była szczegółowa analiza obowiązujących strategii rozwoju małych miast w odniesieniu do przemysłu. Jak wskazują wyniki badań, zaobserwowano marginalizację roli przemysłu w strukturze pracujących, co znalazło odzwierciedlenie w braku miast o przemysłowej, a nawet przemysłowo‑usługowej dominacji funkcjonalnej. Wcześniejsze badania (Kwiatek‑Sołtys, 2017) pokazały, że wyższa pozycja małych miast w rankingu poziomu społeczno‑gospodarczego jest charakterystyczna dla ośrodków, w których funkcje przemysłowe są rozwijane w różnego rodzaju specjalnych strefach działalności gospodarczej, w tym specjalnych strefach ekonomicznych położonych w obszarach metropolitalnych. Spośród analizowanych strategii miast małych w województwie małopolskim jedynie pięć zawierało bezpośrednie odniesienia do przemysłu. Większość z nich dotyczyła wspierania nowych stref przemysłowych i inwestycyjnych, a także tworzenia warunków do rozwoju przemysłu, w tym technologii przyszłości. Pozostałe gminy skupiały się głównie na zwiększeniu aktywności gospodarczej, co mimo potencjalnych powiązań nie zawsze przekłada się na konkretne wsparcie dla sektora przemysłowego. Przeprowadzona analiza ujawnia więc brak jednolitego podejścia do przemysłu w strategiach rozwoju.

Developing efficient and scalable synthetic protocols for key polymer precursors is crucial to advancing high-performance materials designed to withstand severe thermal environments. In this article, we report on the development of solid, high-yield methods for preparing structurally diverse building blocks, including s-triazine derivatives, phenyl-borosilane alkynyl oligomers, phthalonitrile-based monomers, and novel diamine curing agents on multi-gram to multi-hundred-gram scales. These carefully optimized procedures use readily available starting materials, mild conditions, and well-known synthetic transformations, thus addressing the longstanding challenges associated with their practical upscaling. The resulting library of monomers and oligomers offers a broad range of reactive functional groups (e.g., nitriles, alkynes, borosilane motifs), enabling future combinatorial-like strategies for the formation of advanced co-polymers with enhanced thermal stability, mechanical strength, and tunable properties suitable for high-temperature applications.

Phenytoin-induced cerebellar symptoms – A case report
Authors: Nivethia K. R. , Shanthi M. , Nitya S.
Published: December 2024

Phenytoin, a hydantoin derivative, is an effective anticonvulsant drug widely used to treat seizure disorder. The wide pharmacokinetic variability and low toxicity threshold of phenytoin often contribute to its toxicity. We now report the case of a 43-year-old woman who was hospitalized with ataxia, nystagmus, external ophthalmoplegia, drowsiness, gingival hypertrophy, vomiting, and generalized weakness for 10 days while she was on treatment with T. phenytoin 200 mg/day for the past 6 months for seizure disorder. Two days before the onset of these symptoms, the dose of T. phenytoin was increased from 200 mg/day to 300 mg/day. Based on her signs, symptoms, and laboratory tests, she was diagnosed with phenytoin-induced poisoning. After stopping the medication, the symptoms improved. She started using oral levetiracetam instead. Based on the Naranjo and the World Health Organization, a causal analysis of the relationship between the patient’s symptoms and phenytoin use was done. The severity of this adverse drug reaction is moderate at level 4 on the Hartwig severity rating scale. These data highlight the adverse effects of phenytoin and the importance of clinical monitoring for a drug with a narrow therapeutic index.

Published: December 2024

OBJECTIVE: The aim of this study is to evaluate variation of the periodontal diagnosis (according to 2017 classification) and treatment planning of two periodontal cases among specialists and residents of Periodontics and other restorative dental specialists (Prosthodontics and Operative & Endodontics) and General Dental Practitioners.

METHODOLOGY: A cross-sectional study included 3 cohorts (general dental practitioners, periodontists and other restorative specialists). Stratified sampling technique by using proportional allocation was used to collect data. Electronic questionnaire was filled by the dentists in face-to-face meeting. The questionnaire contained two clinical cases of periodontitis, followed by a question regarding diagnosis using 2017 periodontal classification, treatment options and radiographic judgment about bone loss. There responses were compared among groups using descriptive statistics, Chi-square test, binary and multinomial logistic regression model.

RESULTS: 290 questionnaires were obtained in total. Multivariate regression analysis disclosed that highest number of correct diagnosis in case 1 and 2 were made by periodontists; Large proportion of general dentists diagnosed case 1 correctly but failed to correctly diagnose case 2. Restorative specialists fail to diagnose both cases (p>0.05) according to 2017 classification when compared to periodontists. Regarding questions about treatment planning, there was an agreement related to quadrant wise scaling over the other options but significant differences (p<0.01) was found among periodontists when compared to restorative specialists and general dentists in prescribing systemic antibiotics and local antimicrobials in the initial phase.

CONCLUSION: Periodontists had significantly more correct responses than general dentists in diagnosis and treatment plan. The study also showed that the overall agreement of practitioners towards diagnosis and clinical judgment about the bone loss was suboptimal but agreed to suggest appropriate initial non-surgical periodontal therapy for both cases irrespective of their specialty.

Authors: Kuchana Madhavi , Chelimela Ramya , Mandyam Srinivasulu Puja Sri , Shaik Naailah Sulthana
Published: December 2024

Computer-aided drug design (CADD) plays a key role in modern drug discovery. In the present in silico study, two sets of compounds were developed computationally considering the structures of juarezic acid and avenalumic acid. In the first set (compounds 1 – 8), the carboxylic acid group was replaced by ester, amide or nitrile. In the second set (compounds 9 – 16), α-nitrile substituent was introduced and verified its effect on molecular properties especially log P, hydrogen bond acceptor and TPSA as well as druglikeness, pharmacokinetics, bioactivity score and toxicity using Molinspiration Cheminformatics, SwissADME and OSIRIS Property Explorer. All the compounds were evaluated in silico and were found to obey Lipnski’s rule confirming their druglikeness and pharmacokinetic properties. Among all, avenalumic acid, avenalumamide, α-cyanoavenalumic acid and juarezic acid (compounds 5, 7, 13 and 1) were estimated as active enzyme inhibitors. Additionally, α-cyanoavenalumic acid 13 was estimated as an active nuclear receptor ligand. These observations indicate the essential structural requirements like phenolic hydroxyl group, a diene system conjugating with carboxylic acid or amide and α-nitrile substitution for the bioactivity as enzyme inhibitor and nuclear receptor ligand. Most of the compounds appear to have BBB permeability and low toxicity risks. Hence, they may be synthesized and screened for their CNS activity.

Authors: Khandelwal Vishnu Kumar
Published: December 2024

In this work, the methylene blue dye was degraded from an aqueous solution using silver nanoparticles. The silver nanoparticles were investigated by Fourier Transform Infrared Spectroscopy, Zeta Potential, Particle Size Analysis and UV-Visible spectroscopy. The samples were found to be active and to contain silver nanoparticles as indicated by the absorbance peak observed at approximately 420 nm. The size distribution analysis using PSA confirmed that the sample is in the nano range with an average particle size of 47 nm.

Zeta potential confirms the dispersion, colloidal characteristics and stability of the nanoparticle. Zeta potential showed a strong negative value, indicating that the silver nanoparticles are stable and suitable for use in additional experiments. The FTIR analysis also revealed active peaks, indicating the presence of active bonds in the sample that can interact with the methylene blue dye to decolorize it. After six hours of incubation, the nanoparticles successfully adsorbed three milligrams per liter of methylene blue dye.

New nanomaterials and nanocarriers have enabled a significant push to improve the delivery of cancer medications. The multiple pharmacological, biological and physical obstacles that the body presents which frequently obstruct effective treatment, can be circumvented using nanoparticles (NPs). The basic objective of the majority of nanocarrier uses is to prevent the medication from quickly degrading after systemic administration and permit it to penetrate the cancer site at therapeutic concentrations while reducing drug delivery to normal locations as much as possible to reduce adverse effects. Lung cancer is a fatal condition that affects a lot of individuals worldwide and it is becoming more common each year. The use of advanced nanotechnology in the diagnosis and cure of lung tumor have grown in prominence. Recent developments in nanotechnology have increased the field's application to cancer prevention, therapy and diagnosis.

Researchers have access to a variety of alterable molecules for application in cancer attributed to the specific physicochemical properties of substances at the nanostructures. Various NP formulations were created as a result of this understanding and several of these are presently undergoing clinical trials. This study gives a little background on the scientific advancements in the nanotechnology sector, underscoring the significance and necessity in the fight against lung cancer.

This experimental study aims to develop an approach to quantify dimensional changes in the lower body of female football players, with the intention of demonstrating how the results can be used to inform the development of lower body sports compression garments. A framework was established in order to analyse 3D body scans in functional postures using Rhinoceros 3D® and Grasshopper as a response to the limitations of current scanner software. The outcome provides an alternative methodology to locate landmarks on the body and extract dimensions in various sporting postures. Suggestions have been made as to how this information can aid pattern making, sizing, and grading of sports compression leggings, that can provide the wearer with optimal clothing fit, pressure delivery and comfort.
