An Operationalized Model For Defining Computational Thinking, Tony A. Lowe, Sean B. Brophy

School of Engineering Education Graduate Student Series

The Computational Thinking (CT) conceptual framework is entering its second decade of research yet still lacks a cohesive definition by which the field can coalesce. The lack of clear definition makes assessment tool challenging to formulate, pedagogical efforts difficult to compare, and research difficult to synthesize. This paper looks to operationalize differing definitions of CT enhancing the ability to teach then assess the presence of CT. Expanding upon CT definitions, industry practices and processes, and educational theory, we link existing concepts and propose a new element to model an active definition of CT as a theoretical framework to guide future …

Understanding The Impact Of Strategic Team Formation In Early Programming Education, Tony A. Lowe, Sean B. Brophy

School of Engineering Education Graduate Student Series

This evidence based research looks at the impact of a team-based instruction on learning to program in a first year engineering course designed under the Bauhaus studio model. Each team is formulated with a “more knowledgeable other” [1], or for this paper the “ringer” based on selfreported prior learning. 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 …

Teachers’ Incorporation Of Argumentation To Support Engineering Learning In Stem Integration Curricula, Corey A. Mathis, Emilie A. Siverling, Aran W. Glancy, Tamara J. Moore

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

One of the fundamental practices identified in Next Generation Science Standards (NGSS) is argumentation, which has been researched in P-12 science education for the previous two decades but has yet to be studied within the context of P-12 engineering education. This research explores how elementary and middle school science teachers incorporated argumentation into engineering design-based STEM (science, technology, engineering, and mathematics) integration curricular units they developed during a professional development program. To gain a better understanding of how teachers included argumentation in their curricula, a multiple case study approach was conducted using four STEM integration units. While evidence of argumentation …

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

An understanding of statistics and skills in data analysis are becoming more and more essential, yet research consistently shows that students struggle with these concepts at all levels. This case study documents some of the struggles four groups of fifth-grade students encounter as they collect, organize, and interpret data and then ultimately attempt to draw conclusions or make decisions based on these data. The activities in which the students engaged were part of an integrated science, technology, engineering, and mathematics (STEM) unit that had students collecting and analyzing data both in the context of learning science concepts and in the …

Perspectives On Failure In The Classroom By Elementary Teachers New To Teaching Engineering, Pamela S. Lottero-Perdue, Elizabeth A. Parry

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

This mixed methods study examines perspectives on failure in the classroom by elementary teachers new to teaching engineering. The study participants included 254 teachers in third, fourth, and fifth grade who responded to survey questions about failure, as well as a subset of 38 of those teachers who participated in interviews about failure. The study first examines the literature about failure in the contexts of engineering and education. Failure is positioned as largely normative and expected in engineering, whereas in education, learning and failure have a more tenuous relationship. Identity, failure avoidance, failure as part of the learning process, growth …

Undergraduate Engineers And Teachers: Can Students Be Both?, Malinda S. Zarske, Maia L. Vadeen, Janet Y. Tsai, Jacquelyn F. Sullivan, Denise W. Carlson

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

Today’s college-aged students are graduating into a world that relies on multidisciplinary talents to succeed. Engineering college majors are more likely to find jobs after college that are outside of STEM (science, technology, engineering, and mathematics) fields, including jobs in healthcare, management, and social services. A survey of engineering undergraduate students at the University of Colorado Boulder in November 2012 indicated a desire by students to simultaneously pursue secondary teacher licensure alongside their engineering degrees: 25 percent ‘‘agreed’’ or ‘‘strongly agreed’’ that they ‘‘would be interested in earning grades 7–12 science or math teaching licenses while [they] earn [their] engineering …

Examining Experienced Teachers’ Noticing Of And Responses To Students’ Engineering, Aaron W. Johnson, Kristen B. Wendell, Jessica Watkins

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

Engineering design places unique demands on teachers, as students are coming up with new, unanticipated ideas to problems along often unpredictable trajectories. These demands motivate a responsive approach to teaching, in which teachers attend their students’ thinking and flexibly adapt their instructional plans and objectives. A great deal of literature has focused on responsive teaching in science and mathematics, but there has been little research or professional development on this approach in engineering. In this work, we conducted clinical video-based interviews with six elementary teachers experienced in teaching engineering to discuss what they noticed in their students’ thinking and how …

Elementary Teachers’ Reflections On Design Failures And Use Of Fail Words After Teaching Engineering For Two Years, Pamela S. Lottero-Perdue, Elizabeth A. Parry

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

This mixed-methods study examines how teachers who have taught one or two units of the Engineering is Elementary (EiE) curriculum for two years reported on: students’ responses to design failure; the ways in which they, the teachers, supported these students and used fail words (e.g. fail, failure); and the teachers’ broad perspectives and messages to students about failure. In addition, the study explores how strategies, perspectives, messages, and fail word use may change after two years of engineering instruction. This study builds on previous work about elementary teachers’: perspectives on failure prior to teaching engineering, and responses to and perspectives …

An Assessment Framework For First-Year Introduction To Engineering Courses, Senay Purzer, Kerrie A. Douglas, Jill A. Folkerts, Taylor V. Williams

School of Engineering Education Faculty Publications

In this evidence-based practice paper, we describe an assessment framework that applies to first-year introductory engineering courses. First-year engineering courses cover a variety of learning objectives that address both technical and professional outcomes outlined in ABET. These courses also often involve open-ended design and modeling projects. The assessment of multiple competencies along with open-ended design can be a challenging task for educators. In this paper, we describe a framework that guides instructional processes for effective assessment for student learning. This assessment-centered teaching and learning framework helps connect specific learning objectives to broader learning goals or competencies and on-going formative feedback …

A Cross-Sectional Study Of Engineering Identity During Undergraduate Education, Allison Godwin, Walter C. Lee

School of Engineering Education Faculty Publications

This research paper explores students’ engineering, mathematics, and physics identities across the four years of undergraduate engineering education. The focus of this work are subject-related role identities, or how students position themselves and are positioned by others as the kind of people that engage in engineering, mathematics, or physics. An identity as an engineer is a role identity because it embodies a specific character that an individual plays within a social sphere. In this case, the social sphere is in the process of becoming an engineer. Other research has focused on identity development of engineering students, often either early in …

A Learning Trajectory For Developing Computational Thinking And Programming, Sean B. Brophy, Tony A. Lowe

School of Engineering Education Faculty Publications

A learning trajectory for developing computational thinking and programming This research study identifies the relationship between students’ prior experiences with programming and their development of computational thinking and programming during their first year engineering experience. Many first year programs teach students basic programming constructs using languages like MATLAB or LABView. The reason for this is because the disciplinary schools expect students to transform the constitutive properties that model a system’s behavior into a computer model they can use to analyze a system’s performance. Some undergraduate engineering students are entering college with strong computational backgrounds, while others are not. Peer learning …

Approaches To Coaching Students In Design Reviews, Robin Adams, Tiago R. Forin, Cole H. Joslyn

School of Engineering Education Faculty Publications

Design reviews offer a unique window into understanding how design teachers help their students develop as designers. They are a prevalent practice for helping students develop design thinking expertise, although their structure and content may vary across disciplines. Understanding the teaching that occurs during design reviews can illuminate the ways teachers support students in becoming design thinkers. In this paper, we extend prior work to illustrate disciplinary perspectives of how design teachers help their students develop as design thinkers. The guiding framework is design pedagogical knowledge (PCK), the content-specific and practice-based specialized knowledge of teaching design. We analyzed five sets …

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. …

Examining Engineering Technology Students: How They Perceive And Order Their Thoughts, Anne M. Lucietto, Jennifer Drapinski Moss, Mark French

School of Engineering Technology Faculty Publications

The lack of rigorous research focused on engineering technology students leaves administrators and practitioners in this area without adequate resources to advise and guide this unique population. This absence of research can most likely be attributed to smaller student populations as compared to other related fields, receiving attention, such as engineering. A preliminary systemic review reveals that research defining whom the engineering technology students are and how they think is largely unavailable. This study is expected to further improve our understanding of engineering technology students and how they change over time. Both freshman and senior engineering technology students were asked …

Engineering Technology Graduate Students: Roles Professional Societies Havein Their Formation, Anne M. Lucietto, Diane L. Peters

School of Engineering Technology Faculty Publications

In recent years, there have been several research projects focused on returning graduate students in engineering, those who have significant industry experience before beginning their graduate studies. These projects have focused on both the masters and doctoral levels and have looked at research, coursework, benefits of attending graduate school, and the cost of going back. One of the existing papers has looked at the ways in which professional organizations look on returning students, and how their membership policies affect these students. The issue of how returning students see themselves within professional societies was not addressed. As of yet, none of …

Engineering Technology Students - How Do They Compare To Other Stem Students?, Anne M. Lucietto

School of Engineering Technology Faculty Publications

For many years, students interested in Science, Technology, Engineering, and Mathematics (STEM) majors were easily identified. However, since the realization that the US has a low number of students enrolled in STEM programs, great effort has been expended to encourage youth to pursue careers in these areas. Because of these broad-based efforts, the demographics of students moving into STEM are different from those in the past. There is a noted lack of diversity in students majoring in engineering technology; this is not as prevalent in other STEM fields.

Engineering technology students belong to a unique group. They are formally trained …

Fluid Isolator, Purdue Ect Team

ECT Fact Sheets Archive

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 …
