Increasing Student Learning

Product dissection activities are widely practiced in engineering education as a means of increasing student learning and understanding of core engineering concepts. While recent efforts in this area of research have sought to develop and utilize virtual dissection tools in order to reduce and mitigate the costs of physical dissection activities, little data exists on how virtual dissection impacts student learning and understanding. This lack of data makes it difficult to draw conclusions on the utility of virtual dissection tools for enhancing engineering instruction. In this paper we present the results of a controlled experiment conducted with first-year engineering students developed to examine the impact of virtual dissection on engineering student learning and self-efficacy. Our results revealed that student learning appeared to be unaffected through the use of virtual dissection environments. However, electro-mechanical self-efficacy gains were smaller for students who performed virtual dissection compared to students who performed physical dissection. These results add to our knowledge of the impact that virtual dissection tools can have on student learning and understanding and enable us to develop recommendations and guidelines for improving the effectiveness of these tools in engineering education.

The Impact

Product dissection, or the systematic disassembly of design products, has been utilized in engineering education in order to better prepare students for industry. Despite the common use of product dissection in engineering classrooms, knowledge is lacking about how effective different methods of dissection are for encouraging learning and student engineering self-efficacy. This is problematic because without this knowledge, we do not know what components of product dissection impact (positively or negatively) learning. Therefore, the purpose of this study was to identify the impact of dissection virtuality (physical and virtual), product power source (electrical and manual), and product complexity (simple and complex) on efficiency, learning, and engineering self-efficacy through a factorial experiment with 30 engineering students. The results of the study show that virtual dissection is more efficient than its physical counterpart and also maintains the same learning benefits as physical practices. These results are used to develop recommendations for the use of product dissection in education and propel future research that investigates relationships between example-based design practices and student learning outcomes.

Abstract Introduction Latinx students are the largest ethnic/racial minority group in higher education, but are also the group least likely to graduate from a four-year institution. Research suggests that heightened stress perceptions may impede college students’ ability to perform well academically. Poorer sleep may compound the impact of stress on academic functioning. The present study examined the multiplicative effect of college-stress and actigraphy-measured sleep on academic cognitions within-and-across semesters. Methods 209 Latinx college students (Mage=18.95; 64.4% female, 85.1% Mexican descent) were assessed in the spring of the first year of college (T1) and fall of the second year (T2). At T1, participants wore an actigraph watch for 7 nights to measure total sleep time, sleep efficiency, and sleep midpoint. College-stress was assessed at T1 using the College Stress Scale. At T1 and T2, participants completed the Behavioral-Emotional-Cognitive School Engagement Scale, the Academic Self-Efficacy Scale, and a scale assessing academic motivation. Confirmatory factor analysis (CFA) was conducted to assess the model fit of a two-factor model representing academic cognitions (engagement, self-efficacy, motivation) at T1 and T2. Latent variable path analysis models testing for moderation were conducted using Mplus. Results The CFA indicated excellent fit (χ2(5)= 2.91, p=.71, RMSEA=.00, CFI=1.00, TLI=1.01, SRMR=.02). College-stress was concurrently (β=-.19, p=.02), but not longitudinally, associated with academic cognitions. Sleep midpoint predicted academic cognitions at T1 (β=-.24, p<.01) and T2 (β=-.18, p=.03). Sleep efficiency (β=.18, p=.01) and sleep midpoint (β=-.17, p=.02) moderated associations between college-stress and T2 academic cognitions. Higher college-stress was longitudinally linked with lower academic cognitions for students with lower sleep efficiency (b=-.12, p=.01) and later sleep midpoints (b=-.14, p=.01). Conclusion Greater college-stress is concurrently linked with lower academic cognitions, whereas later sleep timing has both immediate and enduring consequences on students’ academic mindsets. The impact of college-stress on academic cognitions may depend on the quality and timing of sleep at the time of these stress perceptions. Programs that address stress reduction and sleep health may be promising interventions for improving academic well-being among first-year Latinx college students.

The Impact

The authors examine the changes and opportunities in the educational environment that will occur as packaged courseware and virtual access to laboratories are assimilated into the engineering curriculum worldwide. The impact on Universities and in turn on Canadian industry will be major unless there is a coordinated effort that can turn the challenge into an opportunity. The opportunity, the authors believe, is to use this new material to allow innovative approaches to education that use Design to direct student learning. The major benefits would be a greater appreciation of technology and practice and significantly improved communication skills, (both of which are regarded as essential by industrial employers). The authors believe that the engineering science background would be enhanced rather than weakened by the approach suggested.

Abstract Background Self-efficacy is a pivotal factor in the etiology and prognosis of major depression. However, longitudinal studies on the relationship between self-efficacy and major depressive disorder (MDD) are scarce. The objectives were to investigate: (1) the associations between self-efficacy and the 1-year and 2-year risks of first onset of MDD and (2) the associations between self-efficacy and the 1-year and 2-year risks of the persistence/recurrence of MDD, in a sample of first-year university students. Methods We followed 8079 first-year university students for 2 years from April 2018 to October 2020. MDD was ascertained by the Chinese version of the Composite International Diagnostic Interview (CIDI-3.0) based on self-report. Self-efficacy was measured by the 10-item General Self-efficacy (GSE) scale. Random effect logistic regression modeling was used to estimate the associations. Results Among participants without a lifetime MDD, the data showed that participants with high baseline GSE scores were associated with a higher risk of first onset of MDD over 2 years [odds ratio (OR) 1.04, 95% confidence interval (CI) 1.01–1.08]. Among those with a lifetime MDD, participants with high baseline GSE scores were less likely to have had a MDD over 2 years (OR 0.93, 95% CI 0.88–0.99) compared to others. Conclusions A high level of GSE may be protective of the risk of persistent or recurrent MDD. More longitudinal studies in university students are needed to further investigate the impact of GSE on the first onset of MDD.

Abstract Advancing virtual education through technology is an important step for engineering education. This has been made evident by the educational difficulties associated with the 2020 Covid-19 pandemic. Maintaining educational standards while using virtual learning is something possibly solved through researching new educational technologies. A potential technology that can enhance virtual education is Augmented Reality, since it can show information that would otherwise not be easily experienced or obtained. Traditional learning tools fail to offer the ability to control objects and explore numerous perspectives the way augmented reality can. Augmented reality can be even further enhanced through the addition of animation. Animation could add the ability to see motion, increasing overall understanding as well as increasing the motivation to learn. When motion is not visualized, it must be perceived, which can increase cognitive load and cause the limitations of working memory to be met. Reaching the limits of working memory has been shown to negatively affect learning. Therefore, the purpose of this study was to identify the impact of digitizing product dissection on engineering student learning and cognitive load. Specifically, we sought to identify the impact of Augmented Reality and Animations through a full factorial experiment with 61 engineering students. The results of the study show that the virtual condition with animation exhibited increased effectiveness as a learning tool. It also showed that augmented reality is not significantly different than a virtual environment in the context of product dissection. The results of this study are used to explore future uses of augmented reality and animation in education, as well as lay the groundwork for future work to further explore these technologies.

Langara College, as one of the leading undergraduate institutions in the province of British Columbia (BC), offers the “Applied Science for Engineering” two-year diploma program as well as the “Engineering Transfer” two-semester certificate program. Three project-based courses are offered as part of the two-year diploma program in Applied Science (APSC) and Computer Science (CPSC) departments: “APSC 1010—Engineering and Technology in Society”, “CPSC 1090—Engineering Graphics”, and “CPSC 1490—Applications of Microcontrollers”, with CPSC 1090 and CPSC 1490 also part of the Engineering Transfer curriculum. Although the goals, scopes, objectives, and evaluation criteria of these courses are different, the main component of all three courses is a group-based technical project. Engineering students have access to Langara College’s Makerspace for the hands-on component of their project. Makerspaces expand experiential learning opportunities and allows students to gain a skillset outside the traditional classroom. This paper begins with a detailed review of the maker movement and the impact of makerspace in higher education. Different forms of makerspace and the benefits of incorporating them on first-year students’ creativity, sense of community, self-confidence, and entrepreneurial skills are discussed. This paper introduces Langara’s engineering program and its project-based design courses. Langara’s interdisciplinary makerspace, its goals and objectives, equipment, and some sample projects are introduced in this paper in detail. We then explain how the group-project component of APSC 1010, CPSC 1090, and CPSC 1490 are managed and how using makerspace improves students’ performance in such projects. In conclusion, the paper describes the evaluation of learning outcomes via an anonymous student survey.

The Impact

Product dissection has been highlighted as an effective means of interacting with example products in order to produce creative outcomes. While product dissection is often conducted as a team in engineering design education, the research on the effectiveness of product dissection activities has been primarily limited to individuals. Thus, the purpose of this study was to investigate the impact of the type(s) of product dissected in a team environment on encouraging creative design outcomes (variety, novelty, and quantity) and the underlying influence of educational level and dissection modality on these effects. This was accomplished through a computational simulation of 14,000 teams of noninteracting brainstorming individuals generated by a statistical bootstrapping technique using a design repository of 931 ideas generated by first-year and senior engineering students. The results of the study highlight the importance of educational level, dissection modality, and the number of products dissected on team design outcomes. Specifically, virtual dissection encouraged the exploration of more novel solutions across both educational levels. However, physical dissection encouraged the exploration of a larger variety and quantity of ideas for senior teams while virtual dissection encouraged the same in first-year teams. Finally, dissecting different types of products allowed teams to explore a larger solution space. The findings presented in this study can lead to a better understanding of how to deploy product dissection modules in engineering design education in order to drive creative design outcomes.

The Impact

Design reviews are typically used for three types of design activities: (1) identifying errors, (2) assessing the impact of the errors, and (3) suggesting solutions for the errors. This experimental study focuses on understanding the second issue as it relates to the number of errors considered, the existence of controls, and the level of domain familiarity of the assessor. A set of design failures and associated controls developed for a completed industry sponsored project is used as the experimental design problem. Nondomain generalists (students from an undergraduate psychology class), domain generalists (first year engineering students), and domain specialists (graduate mechanical engineering students) are provided a set of failure modes and asked to provide their own opinion or confidence on whether the system would still successfully achieve the stated objectives. The confidence level for all domain populations decreased significantly as the number of design errors increased (largest p-value = 0.0793), and this decrease in confidence is more significant as the number of design errors increases. The impact on confidence is lower when solutions (controls) are provided to prevent the errors (largest p-value = 0.0334) as the confidence decreased faster for domain general engineers as compared to domain specialists (p = < 0.0001). The domain specialists showed higher confidence in making decisions than domain generalists and nondomain generalists as the design errors increase.
