First-generation college students in engineering accumulate bodies of knowledge through their working-class families. In our ethnographic data of first-generation college students, we identified tinkering knowledge from home and from work, perspective taking, mediational ability, and connecting experiences as knowledge sources brought to engineering. The purpose of this paper was to understand how first-generation college students’ accumulated bodies of knowledge (i.e., funds of knowledge) support their beliefs about performing well in engineering coursework, feeling a sense of belonging in the classroom, and certainty of graduating. Data for this study came from a survey administered in the Fall of 2018 from ten …

Debugging: The Key To Unlocking The Mind Of A Novice Programmer?, Anthony A. Lowe

School of Engineering Education Graduate Student Series

Novice programmers must master two skills to show lasting success: writing code and, when that fails, the ability to debug it. Instructors spend much time teaching the details of writing code but debugging gets significantly less attention. But what if teaching debugging could implicitly teach other aspects of coding better than teaching a language teaching debugging? This paper explores a new theoretical framework, the Theory of Applied Mind for Programming (TAMP), which merges dual process theory with Jerome Bruner’s theory of representations to model the mind of a programmer. TAMP looks to provide greater explanatory power in why novices struggle …

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 …

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 …

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

The ringer is intended to support the team through early programming challenges. In addition to the professor and teaching assistants, having a peer mentor can yield higher satisfaction and confidence in learners [2]. Our analysis evaluates learning outcomes as student progress through the term, comparing performance based on the performance and …

A Systematized Literature Review: Defining And Developing Engineering Competencies, Hossein Ebrahiminejad

School of Engineering Education Graduate Student Series

Essential competencies have been identified for engineers working in industry. These competencies include (but are not limited to) critical thinking, problem-solving, teamwork, and communication. Engineering education research has shown, however, that engineering undergraduate students often fail to develop these crucial competencies. The industry has also noted that recent graduates exhibit competency gaps. To address these gaps, it is important for higher education institutions to seek to understand the competencies identified as necessary in the industry. Moreover, one could argue educational institutions should develop and assess students’ competencies based on these professional demands. This research systematically reviews literature related to this …

Board # 113 : Eegrc Poster: Characterizing Trade-Off Decisions In Student Designers, Molly Goldstein

School of Engineering Education Graduate Student Series

Although design and decision-making are intertwined for practicing engineers, students from elementary school through college and graduate schools are not taught to think through uncertain situations (Howard, 2007) in which information is limited or outcomes are not guaranteed. Trade-offs are a complex element of decision, as the decision-making weighs possible outcomes against their respective costs (Otto &Antonsson, 1991). Although much is understood about how professional designers’ behaviors as compared to novice designers and students (Atmen et al., 2007; Crismond & Adams, 2012; Cross, 2003), there is little research regarding making trade-off decisions from middle school and high school to college. …

The vast majority of construction scheduling software uses a combination of spreadsheets and Gantt charts for developing and depicting Critical Path Method (CPM) schedules. While this paradigm works for the expert scheduler, it is not conducive to collaboration, and it is prohibitively difficult for non-scheduling experts to understand.

NetPoint® provides a dynamic, visual interface conducive to touch and gestural input. Activities are drawn directly on a time-scale and may be placed on the same row or arranged automatically using codes or the WBS. Such control of the presentation makes it easier to communicate the plan to any type of audience. …

Fluid Isolator, Purdue Ect Team

ECT Fact Sheets

The reliability of concrete infrastructure is vital to ensuring daily life, as well as commerce, can progress without interruption. From the pavement of interstate highways to the driveways and sidewalks in a local neighborhood, concrete is expensive to install and often even more expensive, and intrusive, when it needs to be replaced. Unfortunately, to maintain functionality in winter climates concrete is heavily exposed to deicing salts. This not only affects the roads, driveways, and sidewalks where salt is applied directly, but many other areas such as parking and residential garages where vehicles (and people) will track salt along with water …
