Teaching Interdisciplinary Collaboration: Learning Barriers and Classroom Strategies
Richter, David M.; Paretti, Marie C.; McNair, Lisa D. (ASEE, 2009)
Educators have known for some time that simply putting students in teams is not sufficient to teach teamwork; instead, students need explicit instruction and guidance in teaming to work effectively. A similar principle applies to interdisciplinary teamwork: putting students in interdisciplinary teams – an increasingly common practice in engineering education – is not sufficient to teach interdisciplinary collaboration. Nor are traditional teaming skills alone enough to enable students to work effectively across interdisciplinary boundaries. This paper addresses this gap in teaching practices by first briefly identifying barriers to students successfully engaging in interdisciplinary collaboration and defining corresponding measurable learning outcomes. It then focuses in detail on teaching practices designed to help students achieve the learning outcomes. These findings have been developed from a multi-case study of interdisciplinary collaboration in a green engineering program that draws students from multiple engineering disciplines as well as business, industrial design, and related fields.
Self-Organizing Units in an Interdisciplinary Course for Pervasive Computing Design
McNair, Lisa D.; Newswander, Chad; Coupey, Eloise; Dorsa, Edward A.; Martin, Tom; Paretti, Marie C. (ASEE, 2009-06)
We conducted a case study of a design course that focused on bringing together students from engineering, industrial design, and marketing to use pervasive computing technologies to design, coordinate, and build a “smart” dorm room for disabled individuals. The class was loosely structured to encourage innovation, critical thinking and interdisciplinarity. In this environment, teams were created, disassembled, and re-created in a self-organizing fashion. With few norms, teams were expected to be interdisciplinary, form quickly, and work together by creatively integrating their disciplinary expertise. In observing this semester-long class, we found certain conditions that will enhance pedagogical tools designed to expedite team formation and improve collaborative practices in a classroom setting. Similar to open source software development, we found that groups can form randomly in a loosely coordinated environment that is both self-managing and self-directing if instructors create a strong normative foundation to the class. In this case study, we observed that the applied concept of self-organizing buffered with strong faculty input invests group members with a greater commitment to be productive, effective, and innovative.
Definitions of Interdisciplinary Research: Toward Graduate-Level Interdisciplinary Learning Outcomes
Borrego, Maura Jenkins; Newswander, L. K. (Johns Hopkins Univ Press, 2010)
Combining the interdisciplinary studies (primarily humanities) literature with the content analysis of 129 successful National Science Foundation proposals written predominantly by science and engineering faculty members, the authors identify five categories of learning outcomes for interdisciplinary graduate education: disciplinary grounding, integration, teamwork, communication, and critical awareness. They identify important parallels between humanities-based descriptions of interdisciplinary integration and implicit graduate learning outcomes hinted at by engineering and science faculty who more frequently work in teams. Applying the lens of interdisciplinary studies (humanities) to science and engineering provides important depth and focus to engineering and science interdisciplinary learning outcomes, particularly in detailing integration processes.

Student Persistence Through Uncertainty Toward Successful Creative Practice
Mouchrek, Najla; Baum, Liesl M.; McNair, Elizabeth D. (2016-06)
To increase creative practice among students in engineering and other disciplines, an interdisciplinary instructor team developed a cross-college undergraduate course aimed at open ideation and creative inquiry. One skill in the development of creative practice is identifying and addressing uncertainty avoidance behaviors, which are high in engineering students. We leverage research grounded in professional identity and cognitive design processes to study impacts of curriculum designed to address student persistence through, or indifference toward, uncertainty in creative practice. Questions we seek to explore are: What role does uncertainty avoidance play in developing creative practice, especially in interdisciplinary teams? What strategies can be used to overcome that uncertainty? To explore the role of uncertainty avoidance in the course, we analyze observational data of classroom activities, including ideation workshops, public critiques, team discussions, and artifacts of student work. Findings are used to draw conclusions about processes that are teachable in engineering and interdisciplinary learning environments, in terms of uncertainty avoidance and creativity. To this end, we offer initial directions and questions for future work that would contribute to a pedagogical model that helps engineering students succeed in interdisciplinary contexts.
A Longitudinal Study of the Dimensions of Disciplinary Culture to Enhance Innovation and Retention among Engineering Students
Murzi, Homero; Martin, Thomas L.; McNair, Lisa D.; Paretti, Marie C. (2016-06)
The U.S. engineering educational system has been generally slow in developing pedagogies that successfully promote innovative behaviors. Although numerous sources recognize the growing scope and complexity of challenges that lie ahead in the 21st century, engineering is struggling to balance its goals between the high-risk pursuit of innovation and the traditional problem-solving approach of producing functional, reliable applications. In short, engineering needs more creativity and interdisciplinary fluency, but not at the expense of its discipline-specific problem-solving skills. At the same time, engineering programs continue to struggle with attracting and retaining members of underrepresented populations—whose diversity could greatly contribute to innovation. Interestingly, this lack of diversity is often attributed to cultural traits of the field—often characterized as masculine, individualistic and function-oriented. Notably, students in fields that emphasize functionality (e.g. engineering) rather than creativity (e.g. industrial design) express higher levels of uncertainty avoidance. Together, these cultural dimensions of engineering continue to limit innovative practices, such as interdisciplinary collaboration, design thinking, and diversity of perspectives. The purpose of this study is to investigate patterns of cultural traits in students across disciplines, with the goal of building an actionable theory of engineering culture that can support pedagogies of inclusive and collaborative innovation. Specifically, we are using Hofstede’s theory of dimensions of national culture to understand engineering disciplinary culture. We are using an instrument to evaluate the original four dimensions of national culture (power distance, uncertainty avoidance, individualism, masculinity) to see if the dimensions map to academic disciplines to explain how students develop skills to operate within and across disciplinary boundaries. Furthermore, we are exploring the relationships between these dimensions of disciplinary culture and student recruitment and retention, particularly for underrepresented groups. We are in the third year of a mixed methods study. During year 1, 1043 students from all the disciplines at one institution were surveyed. In year 2, 1199 undergraduate students across 6 institutions were surveyed, and 5 students in electrical and computer engineering were interviewed. During year 3, the survey will go out during the spring semester 2016, and 24 students will be interviewed. Quantitative results describe how undergraduate students in different disciplines understand their culture in terms of Hofstede’s dimensions. However, although we were able to confirm the validity of the instrument with the quantitative data collected, there have not been statistically significant differences between the majors studied, suggesting that the instrument used was to measure the dimensions of culture at the national level rather than at the academic level. In order to continue exploring whether Hofstede’s national cultures map to disciplinary cultures in universities, we are collecting qualitative data (informed by the quantitative results) to obtain in-depth information of how students understand and perceive their disciplines in terms of Hofstede’s dimensions. Results from our research will provide valuable information to understand disciplinary cultures in engineering majors, and contribute to better understanding how to improve engineering culture to make engineers more innovative, to make engineering classrooms more welcoming and inclusive, and to make better decisions regarding curriculum development in engineering.
Disciplinary Influences on the Professional Identity of Civil Engineering Students: Starting the Conversation
Groen, Cassandra J.; Simmons, Denise Rutledge; McNair, Elizabeth D. (2016-06)
As the discipline of civil engineering has evolved from an apprentice-based trade to a socially-engaged profession, the role of the civil engineer has responded to shifts within the ever-changing culture of society. These shifts and historical events have directly influenced what is considered to be valued civil engineering knowledge, behaviors, and practices that we teach to students during their undergraduate careers. As part of a larger grounded theory study that is currently being conducted by the authors, the purpose of this paper is two-fold. First, we present the topic of professional identity formation as heavily influenced by unique historical events that shape the civil engineering discipline. . To establish the connection between identity formation and the history of civil engineering, we interpret historical events as constituents that create a disciplinary identity that is communicated to and subjectively applied by students during their undergraduate careers. Second, we hope to promote and invoke conversations surrounding the relevancy of civil engineering professional identity formation in engineering education among our colleagues within the technical disciplines. Through this paper, we add to ongoing research exploring the professional formation of engineering identities and promote discussions surround this topic at the disciplinary level. While most research conducted on identity formation has been generalized to include all or most engineering disciplines, we focus our discussion solely on professional identity formation within the civil engineering discipline. To reinforce the relationship between the history of the civil engineering profession and students’ professional identity formation, we review the literature on these two areas of inquiry. In particular, we will frame our paper using the following key discussion points: 1) providing a brief overview of key historical events of civil engineering in the United States; 2) discussing the influence of this history on instructor pedagogies and student learning within civil engineering education; and 3) conceptualizing this learning process as a means of professional identity formation. From this work, we will begin to understand how major historical shifts within our discipline maintain the potential to impact its future as we educate the next generation of civil engineering students. To conclude this paper, we will introduce current research that is being conducted by the authors to further understand the nuances of professional identity formation in undergraduate civil engineering students and how instructors may help or hinder that development.
Examining Students' Metacognitive Awareness Through Analysis of Student-generated Learning Responses
Goldberg, Saryn R.; Rich, Jennifer; Masnick, Amy; Paretti, Marie C.; Groen, Cassandra J.; Lutz, Benjamin David; McNair, Elizabeth D. (2016-06-27)
This work-in-progress provides a preliminary exploration of students’ metacognitive monitoring abilities by analyzing written self-evaluations of statics problems. Metacognitive approaches to learning encourage students to examine their own thinking processes as a means of deepening their understanding. We used qualitative coding to analyze students’ level of metacognitive awareness regarding both their ability to solve a given problem and their ability to identify sources of error. The full data set includes 10 response sequences (homework solution and student writing about their solution) from 69 students. In this paper, we present the analysis of two of these sequences, one from early and one from later in the semester. The findings show that for both assignments, about half the students recognized their inability to solve the problems correctly, though in both cases the groups were split between those who could accurately identify one or more sources of error and those who could not. This finding points to the need for teaching practices that can help students develop the ability both to accurately assess their performance and, perhaps more importantly, identify sources of error and confusion that can then lead to successful learning.

MAKER: An Ethnography of Maker and Hacker Spaces Achieving Diverse Participation
Riley, Donna M.; McNair, Lisa D.; Masters, Sheldon (ASEE, 2017-06)
Some have hailed the emergence of maker spaces as an opportunity to broaden participation of underrepresented groups in science, technology, engineering, and math (STEM) education, engaging participants in open, creative, and supportive spaces for learning and applying practical STEM knowledge. Others have questioned the potential of these spaces, as many maker and hacker spaces seem to be enacting certain norms that are more conducive to participation of white, male, middle-class, able-bodied hobbyists. Nonetheless, there are spaces noted for participation of homeless makers, women, people of color, and people with different kinds of abilities. This project considers how diverse maker spaces are conceived, constructed and operated to actively involve groups traditionally underrepresented in STEM, and collectively identify practices that can inform the design and operation of campus and community maker or hacker spaces that presently struggle to achieve diversity. The research employs ethnographic methods and Critical Discourse Analysis (CDA) to characterize spaces in terms of their physical and linguistic artifacts. Here we report results from preliminary research examining online and published artifacts from our cohort of diverse maker spaces in preparation for direct observations beginning in summer 2017. Research questions explored through this first phase of the project include: (1) What practices and artifacts do participants in diverse maker and hacker spaces employ to establish and maintain environments that are diverse and inclusive? (2) What does the discourse in diverse maker and hacker spaces reveal about how meaning and value are co-constructed around identity, creativity, and the culture of production / the production of culture in engineering? (3) What best practices emerge from diverse maker and hacker spaces, and how can these translate to design or transformation of existing maker spaces on campuses and in communities?
Engineering Student's Ethical Awareness and Behavior: A New Motivational Model
Bairaktarova, Diana; Woodcock, Anna (2017-08)
Professional communities are experiencing scandals involving unethical and illegal practices daily. Yet it should not take a national major structure failure to highlight the importance of ethical awareness and behavior, or the need for the development and practice of ethical behavior in engineering students. Development of ethical behavior skills in future engineers is a key competency for engineering schools as ethical behavior is a part of the professional identity and practice of engineers. While engineering educators have somewhat established instructional methods to teach engineering ethics, they still rely heavily on teaching ethical awareness, and pay little attention to how well ethical awareness predicts ethical behavior. However the ability to exercise ethical judgement does not mean that students are ethically educated or likely to behave in an ethical manner. This paper argues measuring ethical judgment is insufficient for evaluating the teaching of engineering ethics, because ethical awareness has not been demonstrated to translate into ethical behavior. The focus of this paper is to propose a model that correlates with both, ethical awareness and ethical behavior. This model integrates the theory of planned behavior, person and thing orientation, and spheres of control. Applying this model will allow educators to build confidence and trust in their students' ability to build a professional identity and be prepared for the engineering profession and practice.
The Effects Of Gender, Engineering Identification, And Engineering Program Expectancy On Engineering Career Intentions: Applying Hierarchical Linear Modeling (HLM) In Engineering Education Research
Tendhar, Chosang; Paretti, Marie C.; Jones, Brett D. (Clute Institute, 2017-12)
This study had three purposes and four hypotheses were tested. Three purposes: (1) To use hierarchical linear modeling (HLM) to investigate whether students’ perceptions of their engineering career intentions changed over time; (2) To use HLM to test the effects of gender, engineering identification (the degree to which an individual values a domain as an important part of the self), and engineering program expectancy (one’s belief in the possibility of his or her success in engineering) on the growth trajectory of students’ engineering career intentions; and (3) To introduce the uses of longitudinal design and growth curve analysis in engineering education research. Survey data was collected at four time points using measures that produce scores with known validity. Sample sizes at each time point were 470, 239, 129, and 115, respectively. We used SPSS 22.0 to perform descriptive statistics and reliability analyses, and HLM version 7.0 to analyze growth. Between their first and third years, undergraduate students’ perceived engineering career intentions neither grew nor declined significantly, with no significant difference between male and female students. Engineering identification significantly predicted individual differences when controlling for engineering program expectancy, whereas engineering program expectancy did not predict career intentions when controlling for engineering identification. These findings are possibly signs of overall stabilization of the declining trends in career intentions and reversal of women’s perceptions of commitment to engineering careers. The contributions and limitations of this study are also discussed.
Assessing systems thinking: A tool to measure complex reasoning through ill-structured problems
Grohs, Jacob R.; Kirk, Gary R.; Soledad, Michelle M.; Knight, David B. (2018-06)
An increasingly important aim of higher education is to develop graduates capable of addressing complex, interdependent problems. Systems thinking is a critical interdisciplinary skill that describes the cognitive flexibility needed to collaboratively work on problems facing society. Although institutions of higher education are asked to develop systems thinkers and many programs strive towards such an aim, mechanisms to assess this competency are lacking. This paper (1) presents a framework for operationalizing systems thinking competency, and (2) shares a novel scenario-based assessment tool based on the framework. The paper describes the iterative development of the community-level problem scenario and associated scoring rubric based on a set of 93 student responses. Appendices contain the full tool consisting of the problem scenario, scoring rubric, and other guiding documents to enable others to adopt the tool for research purposes or to assess student outcomes from university programs.
Characterizing capstone design teaching: A functional taxonomy
Pembridge, James J.; Paretti, Marie C. (2019-04)
Background: Capstone design courses represent a critical juncture in students' development at the transition from school to work. However, few studies have systematically explored teaching in this context, leaving a significant gap in our ability to concretely describe faculty practices in ways that support subsequent explorations of the relationships between teaching practices and learning outcomes. Purpose/Hypothesis: The aim of this study was to develop a comprehensive description of the pedagogical practices used by capstone design faculty from a functional perspective and provide researchers with a framework for subsequent work. Design/Method: This study used qualitative methods to analyze interviews with 42 capstone faculty; the participants represent a stratified purposeful sample of respondents to a national survey. Analysis focused on descriptive coding, beginning with a priori codes, to define broad functions, supplemented with emergent coding to identify concrete practices used in the capstone context. Results: The study resulted in a model of capstone design teaching that includes nine functions (challenge, protect, coach, promote employability, provide exposure, provide role models, accept and confirm, counsel, and build rapport) and 28 associated practices. Conclusions: Capstone faculty use a range of practices designed not only to coach students through the engineering design process but also to more broadly prepare students for workplace practice and build their identity as engineering professionals.
Work in progress: Creating a climate of increased motivation and persistence for electrical and computer engineering students: A project-based learning approach to integrated labs
Ball, Arthur; Baum, Liesl M.; McNair, Lisa D. (2019-06-15)
This work in progress studies the impact on students and faculty and their perceived value of integrating project-based labs with lectures on student learning in a sophomore-level electrical and computer engineering course. Historically, engineering courses have been structured with a division between the theoretical lecture and the applied lab, preventing students from making clear connections between the two. Today's students do not find this legacy approach effective [1], [2]. In order to enhance student learning and concept retention in a large electrical and computer engineering program, a faculty team is redesigning the sophomore year experience using a project-based learning approach. This study describes the work of one instructor teaching a freshman-level course as part of the experience of exploring the full integration of labs and lectures that incorporate industry-level, real-world problems. The questions we seek to address are: How does integration of project-based lab and lecture contribute to students' perceptions of value, motivation and success? How does integration of project-based lab and lecture contribute to instructors' perceptions of value and motivation to modernize instruction? In this paper we discuss the historical approach to the design of the course, which we discovered was from the early 1980s, the time of the last major curriculum revision. In addition, using the MUSIC Model of Academic Motivation together with course data, we present baseline data from current students and instructors in regards to overall performance. Finally, using the MUSIC Model and course data from instructors and students in the revised course, we report some insight on perceived value and performance in order to make comparisons between the old and revised curriculum. Additional data sources were pulled from student feedback as well as analytic memos from the instructor. For the purpose of this paper, the combination and cross-analysis of this data resulted in a set of lessons learned and recommendations for faculty looking to adjust the design of their course to be more integrative. For the broader purpose of this grant project, this data will be used to influence the trajectory of the course and refine methods for more thorough integration of the labs. While our original expectation was that the integration of project-based labs would increase student success, as measured by course grade distribution as well as self-reported perceptions through the use of the MUSIC survey, we actually found little to no change in these measures. In addition, we anticipated the results from the research would reveal that having students participate in industry-level, real-world scenarios would contribute to increased authenticity students assign to the course content, also to which we found little to no change. Even though our original presumptions were unfounded in these two specific quantitative measurements, there are several other factors that have arisen that allow us to nevertheless make meaningful recommendations to other electrical and computer engineering instructors, as well as department administration, as we continue to modernize the student experience.

Outcome Expectations and Environmental Factors Associated with Engineering College-Going: A Case Study
Matusovich, Holly M.; Gillen, Andrew L.; Carrico, Cheryl; Knight, David B.; Grohs, Jacob R. (Purdue e-Pubs, 2020)
Family, school, and community contexts each link to secondary school enrollment, yet these factors have been comparatively examined only in limited ways. A holistic examination of contextual factors will be particularly important for engineering where college enrollment patterns vary by demographics. To begin explaining patterns of engineering college-going at different high schools across the Commonwealth of Virginia, we answered the following research questions: Within a single school system and from a socializer’s perspective, what outcome expectations and environmental factors influence students’ engineering-related postsecondary educational plans? How are these factors the same and different between high schools within a school district? Using a single-case-study approach and in-depth interviews with socializers (teachers, administrators, and counselors), we examined similarities and differences in outcome expectations and environmental factors at three high schools within a single school district. By integrating the results regarding outcome expectations and environmental factors, three important findings emerged: (1) relationships between outcome expectations and environmental factors vary across schools within the same system, (2) proximity to a postsecondary institution is not just about physical distance, and (3) messaging regarding career pathways matters. Each of these has practical implications but can also set the foundation for future research.
Person or thing oriented: A comparative study of individual differences of first-year engineering students and practitioners
Bairaktarova, Diana; Pilotte, Mary K. (2020-02-07)
Background: Engineering practice is meant to advance the human condition, yet curricula do not appear to fully promote the human-centered philosophy of engineering in implementation. The educational system may inadvertently signal to students that engineering is a career choice better suited for those preferring to work with things rather than people. This framing of the profession prompts questions regarding student interests when compared to those of practicing engineers and how such interests become concrete through education and introduction into the profession. Purpose/Hypothesis: We compare engineering students' and practitioners' interest in working with people or things in their environment. We examine gender differences for each sample. Design/Methods: Multiple analysis of variance was used to examine the samples of practicing engineers (n = 339) and first-year engineering students (n = 383). A multiple-group confirmatory factor analysis provides evidence of measurement invariance and justifies the use of the person-thing orientation (PO-TO) scale structure for both samples. Results: Detailed PO values reveal that students' PO scores (n = 383, M = 3.313) are more than one and a half points lower than practicing engineer counterparts examined (n = 339, M = 4.836). However, no significant difference between practicing engineers and students was found for TO. Further, statistically significant differences in PO and TO were found between male and female participants within both samples, students and practicing engineers. Conclusions: Differences detected in PO and TO across the samples suggest possible environmental factors influencing student perspectives of the engineering profession. This condition may inadvertently discourage more diverse students from pursuing engineering.
An Experiential Online Training Approach for Underrepresented Engineering and Technology Students
Mohammadi, Arefeh; Grosskopf, Kevin; Killingsworth, John (MDPI, 2020-02-25)
Workforce pipelines are essential to sustain a productive workforce in an increasingly competitive, high-tech environment. Advanced automation, sensors, materials and data analytics will increase the need for highly skilled workers in the manufacturing (and manufactured construction) sector. Attracting and developing the next-generation workforce is not without its challenges; however, students are often deficient in technical skills and generally have negative perceptions about manufacturing and construction. As a result, new education and training models have been developed to provide instruction at all levels of the educational system, with a focus on both traditional students and non-traditional students, including ethnic minorities, women, veterans, disabled persons and older adult learners. This study focused specifically on certain underrepresented students in STEM programs offered at community colleges in the Great Plains region of the U.S. An available online training program by the Society of Manufacturing Engineers was used as a contextualized online training tool. The Learning Management System embedded in this online training tool was used to gather student data. Conducting multiple regression analyses on the test outcomes, completion rates, and improvement between post-test and pre-test scores showed that female participants achieved greater improvement between pre- and post-test scores than males, and achieved higher rates of credentialing compared to all other demographic groups. African American participants achieved greatest improvement between pre- and post-test scores than all other ethnic groups while Hispanics achieved higher rates of module completion. Additionally, this study also examines the background related to contextualized teaching and learning, as well as the effectiveness of this delivery method for these underrepresented populations.
