Journal of Pre-College Engineering Education Research (J-PEER)

Engineering design activities offer the promise of enhanced learning and teaching in pre-college science, technology, engineering, and mathematics (STEM) settings. The wide variation and lack of coherence in research and practice concerning pre-college engineering design challenges necessitates an investigation of the literature. The overarching research question guiding this search and review of literature was, ‘‘How are engineering design challenges conceptualized in pre-college environments?’’ A search and review coupled with iterative thematic analysis was employed to understand and conceptualize the current body of literature on pre-college engineering design challenges. It is anticipated that this review will provide a general picture of …

Stem Roles: How Students’ Ontological Perspectives Facilitate Stem Identities, Dina Verdín, Allison Godwin, Monique Ross

Journal of Pre-College Engineering Education Research (J-PEER)

Educational researchers have explored the importance of performance, recognition, and interest in establishing and maintaining a STEM identity. Research has also demonstrated that the ways students describe themselves and how they participate in STEM communities can provide insight into their role identity salience; however, there has been little work to explore the ontological beliefs of students about STEM people and how this influences their ability to see themselves as possessing a STEM identity. This research explores the ontological beliefs of high school students, with specific attention to the ways in which they describe what constitutes a math person, science person, …

Taking Professional Development From 2d To 3d: Design-Based Learning, 2d Modeling, And 3d Fabrication For Authentic Standards-Aligned Lesson Plans, Darran R. Cairns, Reagan Curtis, Konstantinos A. Sierros, Johnna J. Bolyard

Interdisciplinary Journal of Problem-Based Learning

There is currently significant interest in 3D fabrication in middle school classrooms. At its best 3D printing can be utilized in authentic design projects that integrate math, science, and technology, which facilitate deep learning by students. In essence, students are able to tinker in a virtual world using 3D design software and then tinker in the real world using printed parts. We describe a professional development activity we designed to enable middle school teachers who had taken part in a three-year Math Science Partnership program to authentically integrate 3D printing into design-based lessons. We include some examples of successful design-based …

A Case Study Of Engineering Students’ Experiences With The Co-Op Application Process, Laura F. Long, Xinrui Xu, Joyce B. Main

The Summer Undergraduate Research Fellowship (SURF) Symposium

Engineering faculty and advisors emphasize the importance of obtaining industry experience in addition to academic learning. One way universities encourage their students to obtain hands-on work experiences is through cooperative education (co-op) programs. Previous studies have examined the advantages and disadvantages of co-op participation, but the application process for students has not been closely examined. Studying this process will show how academic institutions and companies can potentially enhance the student experience of applying for a co-op position. This study examines student experiences with the co-op application process based on interviews with engineering students at a research-intensive university in the Midwestern …

"I Don't Belong With All The Really Smart Kids Here": Student Characterizations Of Belonging In Engineering, Lisa J. Musselman, Jacqueline A. Rohde, Brianna S. Benedict, Allison Godwin

The Summer Undergraduate Research Fellowship (SURF) Symposium

This research paper is a qualitative study of how students with diverse demographics, mindsets, and identities describe what it means to belong in engineering. Engineering students’ sense of belonging has a significant impact on students’ decisions to leave engineering. Talented students who feel that they do not belong in engineering are more likely to leave than their peers. Previous studies have focused on belonging for underrepresented students in engineering (e.g., women or minorities) or specific factors contributing to student belonging (e.g., classroom performance). However, few have explored how students describe what it means for them to belong in engineering to …

Misconceptions And The Notional Machine In Very Young Programming Learners, Tony A. Lowe

School of Engineering Education Graduate Student Series

This study looks at very young learners make mistakes and possibly form misunderstanding when learning to programming. A variety of national efforts are extending programming education to younger learners who are materials many adults struggle to learn. For decades literature has captured common misconceptions in using programming constructs (e.g. conditionals, loops, and recursion) in older learners, but early learners may wait years before they tackle these complex concepts. Many model misconceptions as a missing or inaccurate notional machine. The notional machine is an individual’s mental model, representing how a programming language executes on a real device. The notional machine aligns …

Engineering Technology And Engineering Program Comparison Of Underrepresented Students In The Same Institution, Anne M. Lucietto, Lesley M. Berhan

School of Engineering Education Faculty Publications

Engineering programs include far fewer African American students than engineering technology students enrolled in four-year programs at universities offering both ABET accredited programs. Several studies show this contrast, suggesting that further research in this area is warranted. The rationale for the higher population of students consistently in one program over the other is generally unknown. While researchers study the engineering population, the engineering technology population goes relatively unnoticed. The effects of a student’s past and current environments in engineering technology are relatively unknown. Researchers developed a survey to gather data from underrepresented populations in universities that meet the noted criteria. …

International Experience Of Engineering Technology Students Learning About Renewable Energy, Anne M. Lucietto

School of Engineering Education Faculty Publications

Cultural exposure is said to be an enhancement to collegial learning. With this in mind, students in an engineering technology program were given the opportunity to go to Germany to a regional university, experience education in that setting, and visit sites dedicated to renewable energy. The students were given a two-week experience that taught them through both formal and informal means. Ultimately, students experienced curiosity, openness to different cultural norms, and were able to identify components of other cultural perspectives responding with their own worldviews. The researchers utilized the Miville-Guzman Universality Diversity Scale (M-GUDS-S) to assess pre and post activity …

School of Engineering Education Faculty Publications

Technical education or STEM (Science, Technology, Engineering, and Mathematics) education is often touted as the way for students to succeed, for corporations to move forward, and to gain prominence in the world economy. With all this promotion, do we know who is teaching these subjects to our students? This question urged researchers to develop a survey and distribute it to those teaching STEM subjects. The survey collected a variety of information, the results of the demographic section being reported here. The survey responses are from a population of STEM educators teaching at all levels, found to be male and generally …

How To Shape Attitudes Toward Stem Careers: The Search For The Most Impactful Extracurricular Clubs, Fethiye Ozis, Ali Osman Pektas, Mustafa Akca, Daniel’Le April Devoss

Journal of Pre-College Engineering Education Research (J-PEER)

It is well known that strong extracurricular STEM programs provide multiple arenas for students to expand on classroom curriculum, complementing STEM skills with creative thinking and open-ended problem solving. It has been shown that there is a relationship between the number of STEM clubs students participated in and their choice of STEM major (Sahin, 2013). Considering financial problems, including budget cuts, it gets really challenging for schools to provide a plethora of clubs. For this reason, it would be very beneficial for K–12 schools to know if certain clubs are more effective in changing attitudes toward STEM majors, and therefore …

We briefly summarize the history of engineering education as a scholarly field, and we describe the current structures that support engineering education research: academic departments, scholarly journals, annual conferences, and professional societies. We identify the theories that often inform engineering education research studies, including theories of cognition, motivation, and identity. We explain how quantitative, qualitative, and mixed methods have been used. We summarize the results of an illustrative selection of empirical studies across a broad range of topics, including …

First-Generation College Students Identifying As Future Engineers, Dina Verdín, Allison Godwin

School of Engineering Education Graduate Student Series

This paper seeks to understand factors that influence how first-generation college students identify as engineers now and in the future. Data used in this study came from four U.S. institutions obtaining a total first-generation college student sample of 596 participants. We used future possible selves as a lens to understand how first-generation college students’ current views of themselves as engineers shape their future identities as engineers. Two separate analyses were conducted. First, a multiple regression analysis was used to determine which career future satisfaction variables predicted first-generation college students current and future identification as engineers. Second, a hierarchical regression analysis …

Understanding How Engineering Identity And Belongingness Predict Grit For First-Generation College Students, Dina Verdín, Allison Godwin, Adam Kirn, Lisa Benson, Geoff Potvin

School of Engineering Education Graduate Student Series

Increasing the participation of underrepresented students, including first-generation college students, in engineering plays a central role in sustaining the U.S. research and innovation capacity. Diversity continues to be recognized as an asset in engineering. However, we also know that the culture of engineering has an implicit assumption about who can be and who is recognized as an engineer. There is also a complex relationship between participation in a community of practice and identity. Diverse students must not only author an identity as an engineer but also must grapple with how that identity, historically constructed as white and masculine, becomes a …

Engineering Women’S Attitudes And Goals In Choosing Disciplines With Above And Below Average Female Representation, Dina Verdín, Allison Godwin, Adam Kirn, Lisa Benson, Geoff Potvin

School of Engineering Education Graduate Student Series

Women’s participation in engineering remains well below that of men at all degree levels. However, despite the low enrollment of women in engineering as a whole, some engineering disciplines report above average female enrollment. We used multiple linear regression to examine the attitudes, beliefs, career outcome expectations, and career choice of first-year female engineering students enrolled in below average, average, and above average female representation disciplines in engineering. Our work begins to understand how the socially constructed masculine cultural norms of engineering may attract women differentially into specific engineering disciplines. This study used future time perspective, psychological personality traits, grit, …

Choosing Stem College Majors: Exploring The Role Of Pre-College Engineering Courses, L. Allen Phelps, Eric M. Camburn, Sookweon Min

Journal of Pre-College Engineering Education Research (J-PEER)

Despite the recent policy proclamations urging state and local educators to implement integrated science, technology, engineering, and mathematics (STEM) curricula, relatively little is known about the role and impact of pre-college engineering courses within these initiatives. When combined with appropriate mathematics and science courses, high school engineering and engineering technology (E&ET) courses may have the potential to provide students with pre-college learning experiences that encourage them to pursue STEM college majors. Our central research question was: What is the nature and extent of any relationship between high school E&ET course completion and subsequent selection of a STEM major in a …

Mdp (Machine Drive Power) Intelligent Compaction Technology, Purdue Ect Team

ECT Fact Sheets

Caterpillar developed MDP (Machine Drive Power) technology to fill this gap. Rather than an accelerometer and vibratory drum, it uses the principle of rolling resistance to provide indications of soil stiffness. This allows it to perform more reliably on cohesive and granular soils with less variability than accelerometer systems. It also means that the technology can be used on both vibratory and static drum compactors, which are often used on larger sites. While the technology is quite useful on its own, it is even better as a complementary technology to the existing accelerometer-based systems. Contractors who use vibratory soil compactors …

Purdue’S Biowall, Purdue Ect Team

ECT Fact Sheets

Mechanical ventilation, energy recovery ventilation, and infiltration (air that leaks into a building) are commonly used to introduce fresh air. These are all valid approaches, but a living plant-based filter is an innovative complement to these traditional technologies. A Biowall has the potential to improve indoor air quality while reducing the quantity of air needed for ventilation, creating the potential for energy savings. Figure 1 shows a Biowall prototype being evaluated in the ReNEWW House, a research home located near the Purdue University campus (http://www.renewwhouse.com/).
