Achieving What Gets Measured: Responsive and Reflective Learning Approaches and Strategies of First-Year Engineering Students
Van Tyne, Natalie Christine Trehubets (Virginia Tech, 2022-02-24)
Background: Engineering students who achieve academic success during their first year may later disengage from challenging course material in their upper-level courses, due to perceived differences between their expectations and values and those of their degree programs. In the extreme, academic disengagement can lead to attrition. Purpose: The purpose of this study is to better understand the learning approaches and strategies used by first-year engineering students. Research questions were as follows:  How do first-year engineering students describe their learning approaches and strategies?  How do first-year engineering students customize their learning strategies among their courses?  How do first-year engineering students employ reflection as part of their learning strategies? Design/Method: I employed both qualitative and quantitative methods to collect and analyze data, using an explanatory design approach consisting of two surveys and a set of semi-structured interviews between survey administrations. The interview data from a purposive sample of survey participants were coded using a priori, pattern and comparative coding. The survey data were analyzed for medians and interquartile ranges in order to identify trends in reflective learning strategies among courses. Results: One notable finding was the fact that many interviewees stated that their overall purpose for studying was to achieve high grades by preparing for tests (a surface-level approach), and yet the learning strategies that they used reflected a deeper engagement with their course material than one would expect from students whose singular focus was on grades. Certain strategies were similar for both technical and non-technical courses, while others were dissimilar. There are also ways to combine the surface and deep learning strategies sequentially. They need not be mutually exclusive. Conclusions: The results of this study will provide educators with a starting point for the development of guided practice in meaningful learning strategies to encourage a greater engagement with learning. Both educators and administrators should be amenable to measures that would improve their students' chances for success, by providing guidance in how to learn as well as what to learn. Several recommendations are given for future studies, such as the relationships among reflection, metacognition, and critical thinking, and the integration of meaningful learning strategies into technically overloaded engineering degree curricula.
Advancing from Outsider to Insider: A Grounded Theory of Professional Identity Negotiation
Groen, Cassandra J. (Virginia Tech, 2017-04-11)
As evidenced by a large body of research within the engineering education community, those individuals who do not maintain a sense of belonging, identify with engineering groups, or perceive themselves as engineers are more likely to leave the profession. However, little is known about the ways in which engineering students construct or develop their personal and professional identities as influenced by the disciplinary values, behaviors, and practices learned during the undergraduate education experience. In order to deepen the understanding of professional identity formation within the engineering disciplines, a grounded theory study was conducted to explore the experiences of 31 sophomore, junior, and senior level undergraduate students enrolled in a civil engineering program. Upon conducting an iterative process of data collection and analysis, a theory of professional identity negotiation emerged from interviews depicting participants' experiences. This theory titled Negotiating Equilibrium: Advancing from Outsider to Insider or the AOI Model, captures the identities negotiated by students as they iteratively define, adjust, and readjust definitions of self and profession to maintain a balance between their personal self and the learned disciplinary identity of the civil engineering profession. As participants gained this balance, they began to see themselves as professionals and advance from an outsider (i.e., one not belonging to the civil engineering profession) to an insider (i.e., one belonging to the civil engineering profession). The AOI Model provides a framework for researchers to further explore professional identity formation, promotes the development of identity-influencing coursework and instructor teaching approaches, and inspires future research trajectories in engineering and civil engineering education.
Assessment of First-Year Engineering Students' Spatial Visualization Skills
Steinhauer, Heidi Marie (Virginia Tech, 2012-03-30)
This research was undertaken to investigate the assessment of the spatial visualization skills of first-year engineering students. This research was conducted through three approaches: (1) a review of cogent research framed by a spatial visualization matrix, (2) the development and validation of an Engineering Graphics Concept Inventory, and (3) an investigation into the relationship into the correlations between 3D modeling skills and performance on the Purdue Spatial Visualization Test: Rotations (PSVT:R) and the Mental Cutting Test (MCT). The literature reviewed spans the field of published research from the early 1930's to the present. This review expands and provides a new direction on published research as it is viewed through the lenses of the four common pedagogical approaches to teaching spatial visualization: the standard approach, the remedial approach, computer-aided design, and the theory-informed approach. A spatial visualization matrix of criteria was developed to evaluate each of the methods. The four principle criteria included: learning outcomes, active and engaged learning, stage of knowledge, and explanatory power. Key findings from the literature review indicate the standard method is not the most effective method to teaching spatial visualization while the theory-informed method as evaluated by the matrix is the most effective pedagogical approach of the four methods evaluated. The next phase of this research focused on the two-year development, validation, and reliability of an Engineering Graphics Concept Inventory given to over 1300 participants from three universities. A Delphi method was used to determine the key concepts identified by the expert panel to be included in the inventory. A student panel of 20 participants participated in the pilot study of "think aloud" protocols to refine inventory test items and to generate the appropriate distractors. Multiple pilot studies coupled with a detailed psychometric analysis provided the feedback and direction needed for the adjustment of test items. The reported Cronbach's α for the final instrument is .73, which is within the acceptable range. The inventory is ready to be implemented and the predictability of the instrument, in reference to students' spatial visualization skills, to be researched. The final chapter of this research was a correlational study of the relationship between first-year engineering student's 3D modeling frameworks and their performance on the PSVT:R and the MCT. 3D modeling presence in graphical communications has steadily increased over the last 15 years; however there has been little research on the correlations between the standard visualization tests and 3D modeling. 220 first-year engineering students from Embry-Riddle Aeronautical University participated in the study in the fall of 2011. The main findings from this research indicate there is no significant correlational relationship between the PSVT:R and a student's 3D modeling ability, but there is one for the MCT. The significant correlational factors reported for the MCT and modeling aptitude for the three assignments are: r = .32 (p < 0.05), .36 (p< 0.01), and .47 (p< 0.01). These findings may be used by undergraduate educators and course administrators to more effectively organize engineering graphics education to yield students with deeper, more meaningful knowledge about engineering graphics and its inherent connection throughout the engineering curriculum. Together these three studies represent a sequential exploratory mixed methods approach that intertwines qualitative interviews and observations to frame the quantitative instrument and data collection. Results of this study can be used to guide the assessment of incoming freshmen engineering students, and the modification and development of engineering graphics courses.
Beyond the Classroom: Understanding the Educational Significance of Non-Curricular Engineering Design Experiences
Kusano, Stephanie Marie (Virginia Tech, 2015-01-29)
The purpose of my dissertation study is to better understand the educational experiences of undergraduate engineering students within non-curricular learning environments, specifically in the form of extracurricular engineering groups or programs. I first conducted a content analysis of engineering education literature to identify where engineering design learning occurs, and to synthesize the implications of studies regarding engineering design learning. Aiming to fill a gap in the literature regarding non-curricular learning contexts, this study investigated what extracurricular groups and programs can educationally provide undergraduate engineering students by observing and interviewing students engaging in these environments. This study also aimed to identify if and how engineering students find navigational flexibility within engineering curricula, and how non-curricular learning environments might provide navigational flexibility. With regard to where engineering design learning occurs, the literature points to various educational contexts that effectively deliver engineering design education. Strategies that involve authentic and longer-term engineering design experiences tend to be the most impactful in terms of student outcomes and perceptions, however those experiences are not always implementable at larger scale. More traditional educational approaches to engineering design learning, though less impactful, are still effective delivery methods for introducing key aspects of engineering design education (e.g. modeling, global/societal/economic/environmental factors, communication skills). However, there was limited literature regarding more non-curricular learning experiences, such as learning in designed settings, outreach learning, learning media, and everyday informal learning. This literature review is one of the first attempts towards synthesizing where and how engineering design learning occurs, and has identified a significant gap in the literature regarding non-curricular educational settings. Addressing the identified gap in engineering education literature regarding non-curricular learning experiences, this dissertation study investigated five non-curricular engineering learning sites for undergraduate engineering students at a large research-driven state institution. Informed by the preliminary findings of a pilot study, I first investigated the salient features of engineering-related non-curricular activities from the students' perspectives using a self-directed learner autonomy framework to guide the study. Students participating in extracurricular engineering environments exhibited strong attributes of self-directed learners, particularly a willingness and ability to be challenged and to learn. The educational environments of the extracurricular opportunities cultivated these self-directed learning attributes by providing students a space to be exposed to an engineering community, authentic engineering work, and accessible resources. Findings from this portion of the dissertation indicated necessary modifications to the self-directed learner autonomy framework used to guide this study. The modified framework contributes a possible approach towards future assessment or research pursuits regarding non-curricular learning experiences in engineering. I also investigated the role non-curricular activities play in providing engineering students navigational flexibility through engineering curricula. Extracurricular engineering environments afford navigational flexibility by offering students opportunities to work on motivating challenges with and among supportive communities. By providing a space for students to express their engineering selves in primarily self-directed ways, extracurricular engineering experiences cultivate students' drive to find and pursue personally meaningful curricular and non-curricular educational experiences. However, institutional barriers, particularly time constraints and institutionally recognized achievements, stifle students' flexibility and willingness to pursue personally meaningful experiences. The findings of this study have helped uncover the various affordances non-curricular learning experiences provide engineering students, but more importantly, have identified the institutional barriers that prevent students from taking full advantage of non-curricular learning experiences. Based on these findings, I recommend that university and program level structures be reevaluated to encourage and provide students with more flexibility to find personalized learning experiences in and out of the classroom.
Collaboratively Learning Computational Thinking
Chowdhury, Bushra Tawfiq (Virginia Tech, 2017-09-05)
Skill sets such as understanding and applying computational concepts are essential prerequisites for success in the 21st century. One can learn computational concepts by taking a traditional course offered in a school or by self-guided learning through an online platform. Collaborative learning has emerged as an approach that researchers have found to be generally applicable and effective for teaching computational concepts. Rather than learning individually, collaboration can help reduce the anxiety level of learners, improve understanding and create a positive atmosphere to learning Computational Thinking (CT). There is, however, limited research focusing on how natural collaborative interactions among learners manifest during learning of computational concepts. Structured as a manuscript style dissertation, this doctoral study investigates three different but related aspects of novice learners collaboratively learning CT. The first manuscript (qualitative study) provides an overall understanding of the contextual factors and characterizes collaborative aspects of learning in a CT face-to-face classroom at a large Southeastern University. The second manuscript (qualitative study) investigates the social interaction occurring between group members of the same classroom. And the third manuscript (quantitative study) focuses on the relationship between different social interactions initiated by users and learning of CT in an online learning platform Scratch™. In the two diverse settings, Chi's (2009) Differentiated Overt Learning Activities (DOLA) has been used as a lens to better understand the significance of social interactions in terms of being active, constructive and interactive. Together, the findings of this dissertation study contribute to the limited body of CT research by providing insight on novice learner's attitude towards learning CT, collaborative moments of learning CT, and the differences in relationship between social interactions and learning CT. The identification of collaborative attributes of CT is expected to help educators in designing learning activities that facilitate such interactions within group of learners and look out for traits of such activities to assess CT in both classroom and online settings.
Content and Choices: An Exploration of Career Goals in Undergraduate Engineering Students
Brown, Philip Reid (Virginia Tech, 2016-04-29)
The careers that students pursue after graduating from engineering programs are a central component to engineering education. However, we lack perspective on how students, the main stakeholder of the engineering education system, describe the goals they have for their post-graduation careers and make choices related to those goals. As a first step in closing this gap, I explored the different types of career goals that students have, investigated how students connect different types of goals to choices they make in engineering programs, and developed a survey instrument for future research on career goals. My sequential mixed methods study consisted of three phases. In the first phase, I analyzed interview data via the constant comparative method to explore the different types of career goals that students described. In second phase, I used the types of goals identified in phase one to analyze how students described connecting their career goals to choices they made as undergraduates in longitudinal interview data. In the final phase, I adapted the ideas from phase one and phase two into a quantitative survey instrument, which I piloted for validity and reliability. My study produced four main outcomes. The first outcome was identifying two distinct types of career goals held by students including goals about the jobs students want post-graduation and goals relative to job attributes rather than specific jobs. The second outcome was that students connected both types of career goals to choices they make in the present academic context. The third outcome was that career goals and their connection to choices students make could be measured in a valid, reliable survey instrument. Finally, my results suggest that there may be differences in the ways that male and female students describe their career goals and the ways that career goals are connected to choices. These outcomes have broad implications for students, educators and researchers in the engineering education system.
Developing Guidelines for Collaborative Spaces Supporting Interdisciplinary Engineering Design Teams
Kim, Kahyun (Virginia Tech, 2013-04-25)
Communication deficiencies within interdisciplinary teams are known to reduce the effectiveness of those teams by causing erroneous behaviors (Alvarez & Coiera, 2006; Reader, Flin, & Cuthbertson, 2007). Also, many design defects have been attributed to communication breakdowns across disciplines (Chen & Lin, 2004). As the number of interdisciplinary teams in industry grows in order to adapt to dynamic business environments of the twenty-first century, providing an appropriate environment to improve interdisciplinary team effectiveness is critical for many organizations. In spite of its importance, little is known about what kind of environments support interdisciplinary team interactions. There were three objectives of this dissertation: 1) to investigate the influence of physical environment on the effectiveness of interdisciplinary engineering design teams, 2) to investigate the influence of interaction strategy design support on the effectiveness of interdisciplinary engineering design teams, 3) to construct behavioral indicators of successful interdisciplinary teamwork to design testing and design guidelines for interdisciplinary team collaboration spaces. To achieve these goals, the study was conducted in two phases. In Phase 1, the researcher conducted a direct observation of industry teams operating in the novel design space, the Kiva, at a design-consulting firm based in Pittsburgh, PA. The observation data provided 1) a list of significant participant behaviors to be examined and 2) interaction strategy design support (ISDS) procedures to be used during phase 2. Phase 2 was a laboratory-based 2x2 experimental study with physical room condition (Kiva vs. conference room) and interaction strategy design support (present vs. absent) as independent variables. The dependent variables were categorized as team process and output that measured team effectiveness. Overall, a significant interaction effect between the physical conditions and interaction strategy design support was found from all dependent measurements except for product evaluation. A significant main effect of physical conditions and interaction strategy support were found to a lesser extent. Based on the findings, testing methodology guidelines and design guidelines were developed.
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.
Engaging with the Invisible: STS Groundwork in an Electrical and Computer Engineering Department
Patrick, Annie Yong (Virginia Tech, 2022-01-20)
This dissertation is a study of groundwork in Engaged Science, Technology, and Society (STS) research. Engaged STS scholars reframe STS knowledge and move it beyond the traditional scope and boundaries of the field. They use various methods such as critical participation, making and doing, situated interventions, and experimentation to critically engage with their fields of study. These scholars have evaluated their work within the context of the disciplinary outsider, described their use of high-level pragmatic frameworks, and used the arts to bring critical social issues to the public eye. Yet, when I decided to use STS engagement methods to bring visibility to the lesser-known communities in the Bradley Department of Electrical and Computer Engineering (ECE) at Virginia Tech, I found a lack of work documenting the groundwork and experience of engagement. I could not locate groundwork regarding negotiation, designing the most appropriate intervention, collaboration strategies, or confronting my fears and doubts about being in the field. Therefore, in this dissertation, I identify and examine my engagement experience in three interventions within the ECE department to bring visibility to the groundwork of STS engagement. The limited-series podcast Engineering Visibility was a platform to bring visibility to the less dominant communities in the ECE department. Highlighting the experiences of women in engineering, the first-generation student, inclusion and diversity, and the non-traditional student fostered a shared identity and sense of belonging within the ECE department. On the ground, this project examined the need to protect participants' visibility through invisibility. Interventionist Protectivity conceptualizes how I combined trust, accountability, and social awareness to protect my participants' from social scrutiny. The second project was a seminar titled "Expand Your ECE Career." The seminar exposed students to a "broader range of careers" by challenging the traditional ideas of success. The seminar featured four ECE alumni with successful careers in law, finance, and fashion entrepreneurship. Additionally, this intervention pointed out the inadequacies of traditional forms of project assessment. I describe how I measured intervention success through other assessment methods such as "assessment per mobility." The last project was a data-driven white paper that translated the care work of the undergraduate academic career advisors and framed it to be understood by the ECE faculty. The care work done by the academic advisors was underappreciated in its connection to undergraduate student success. On the ground, I discussed the importance of identifying the advisors and the faculty's social construction to create an intervention that translated the advisors' work to be valued by the faculty. Lastly, I conclude with a discussion summarizing the overall lessons learned from the three interventions and discussing my experience of engagement. My engaged STS experience is discussed through my framing of the concept of self-confrontation and the work of avoiding the term of STS being deemed as useful.
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.
Exploring Electronic Storyboards as Interdisciplinary Design Tools for Pervasive Computing
Forsyth, Jason Brinkley (Virginia Tech, 2015-06-09)
Pervasive computing proposes a new paradigm for human-computer interaction. By embedding computation, sensing, and networking into our daily environments, new computing systems can be developed that become helpful, supportive, and invisible elements of our lives. This tight proximity between the human and computational worlds poses challenges for the design of these systems - what disciplines should be involved in their design and what tools and processes should they follow? We address these issues by advocating for interdisciplinary design of pervasive computing systems. Based upon our experiences teaching courses in interactive architecture, product design, physical computing and through surveys of existing literature, we examine the challenges faced by interdisciplinary teams when developing pervasive computing systems. We find that teams lack accessible prototyping tools to express their design ideas across domains. To address this issue we propose a new software-based design tool called electronic storyboards. We implement electronic storyboards by developing a domain-specific modeling language in the Eclipse Graphical Editor Framework. The key insight of electronic storyboards is to balance the tension between the ambiguity in drawn storyboards and the requirements of implementing computing systems. We implement a set of user-applied tags, perform layout analysis on the storyboard, and utilize natural language processing to extract behavioral information from the storyboard in the form of a timed automaton. This behavioral information is then transformed into design artifacts such as state charts, textual descriptions, and source code. To evaluate the potential impact of electronic storyboards on interdisciplinary design teams we develop of user study based around ``boundary objects''. These objects are frequently used within computer-supported collaborative work to examine how objects mediate interactions between individuals. Teams of computing and non-computing participants were asked to storyboard pervasive computing systems and their storyboards were evaluated using a prototype electronic storyboarding tool. The study examines how teams use traditional storyboarding, tagging, tool queries, and generated artifacts to express design ideas and iterate upon their designs. From this study we develop new recommendations for future tools in architecture and fashion design based upon electronic storyboarding principles. Overall, this study contributes to the expanding knowledge base of pervasive computing design tools. As an emerging discipline, standardized tools and platforms have yet to be developed. Electronic storyboards offer a solution to describe pervasive computing systems across application domains and in a manner accessible to multiple disciplines.
Exploring Engineering Faculty Members' Experiences with University Commercialization Utilizing Systems Thinking
Hixson, Cory Allen (Virginia Tech, 2016-08-11)
Since the Bayh-Dole Act of 1980, commercialization (e.g., patenting discoveries, licensing technologies, and developing startups) has become increasingly prominent at universities across the nation. These activities can be beneficial for universities as mechanisms to increase research dollars, unrestricted funds, student success, institutional prestige, and public benefit, while developing an innovation and entrepreneurship culture. However, although faculty members are a key source of human capital within the university commercialization process, studies of faculty members' experiences with university commercialization are scarce. To better understand these experiences, I conducted a multiple case study exploring engineering faculty members' commercialization experiences at three land-grant universities, using Activity Theory as an analytical framework. Each case consists of in-depth, semi-structured interviews with 5-6 engineering faculty members, 1-2 university administrators, and a technology transfer officer, as well as university commercialization documentation (e.g., university commercialization policy documents and web resources). I analyzed the data using provisional coding (activity system elements, supports, challenges, and affect), inductive coding, and within and cross-case analysis techniques. The study's findings include characteristics of the university commercialization activity system, supports for and challenges to faculty engagement, and provisional recommendations to enhance the university commercialization work system. Key findings include faculty members' desire to make an impact with their work, lack of training and expertise relative to commercialization, conflicting attitudes towards commercialization from colleagues and administrations, and tensions about the place of commercialization within the university's mission. This study highlights an important and underrepresented voice in university commercialization research—"the voice of the individual faculty member. By understanding how faculty members experience university commercialization, university leaders are able to make well-informed decisions regarding the university's mission, culture, work structure, resource allocation, and incentive systems related to this increasingly-prominent faculty activity. Moreover, faculty members and industry collaborators interested in university commercialization can use the study's results to make decisions regarding if and how to best proceed with university commercialization activities. Accordingly, this work not only contributes to faculty work system design, but it also contributes a unique systems research approach to the university commercialization literature.
Exploring Programmatic Elements, Learning, and Sense of Belonging in an Engineering Internship Program
Vicente, Sophia (Virginia Tech, 2024-06-11)
In engineering and STEM, internships are upheld as "high impact" practices and recommended to students by faculty, staff, and peers. Furthermore, there is a significant amount of research focused on the positive outcomes and benefits of participating in internship programs. Due to the calls to increase the quality and quantity of internships for students, it is important to explore and deepen our understanding of students' experiences in such programs. Through this dissertation, I explored engineering undergraduate students' experiences in a particular research-focused internship program. Specifically, I explored the influence of programmatic elements on students' experiences, students' perceptions of situated learning, and students' perceptions of sense of belonging in relation to their intent to return. The overarching study and resulting manuscripts provide additional detail to underlying phenomena and mechanisms that contributed to students' experiences in one program. The two most salient findings from the overarching study were the importance of both social interaction and learning in students' experiences. This work suggests key questions for practitioners and those who work with STEM students or internship programs. Future work should be conducted to continue to explore students' experiences in engineering internships and to continue to increase our understanding of how to better educate and train our students.
How Static is the Statics Classroom? An investigation into how innovations, specifically Research-Based Instructional Strategies, are adopted into the Statics classroom
Cutler, Stephanie Leigh (Virginia Tech, 2013-05-03)
The purpose of this dissertation is to investigate how educational research, specifically Research-Based Instructional Strategies (RBIS), is adopted by education practice, specifically within the engineering Statics classroom. Using a systematic approach, changes in classroom teaching practices were investigated from the instructors\' perspective. Both researchers and practitioners are included in the process, combining efforts to improve student learning, which is a critical goal for engineering education. The study is divided into 3 stages and each is discussed in an individual manuscript. Manuscript 1 provides an assessment of current teaching practices; Manuscript 2 explores RBIS use by Statics instructors and perceived barriers of adoption; and Manuscript 3 evaluates adoption using Fidelity of Implementation.

A common set of concurrent mixed methods was used for each stage of this study. A quantitative national survey of Statics instructors (n =166) and 18 qualitative interviews were conducted to examine activities used in the Statics classroom and familiarity with nine RBIS.

The results of this study show that lecturing is the most common activity throughout Statics classrooms, but is not the only activity. Other common activities included working examples and students working on problems individually and in groups. As discussed by the interview participants, each of Rogers\' characteristics influenced adoption for different reasons. For example, Complexity (level of difficulty with implementation of an RBIS) was most commonly identified as a barrier. His study also evaluated the Fidelity of Implementation for each RBIS and found it to be higher for RBIS that were less complex (in terms of the number of critical components). Many of the critical components (i.e. activities required for implementation, as described in the literature) were found to statistically distinguish RBIS users and non-users.

This dissertation offers four contributions: (1) an understanding of current ractices in Statics; (2) the instructor perspective of the barriers to using RBIS in the classroom; (3) the use of Fidelity of Implementation as a unique evaluation of RBIS adoption, which can be used by future engineering education researchers; and (4) a systematic approach of exploring change in the classroom, which offers new perspectives and approaches to accelerate the adoption process.
Improving Dilemma Zone Protection Control Issues at Signalized Intersection Using a Web-Game
Kasaraneni, Yatish (Virginia Tech, 2009-09-04)
Web games provide a platform for creative instructional activities that can capture the students' attention towards the course. These games can be used to emulate the realistic situations which can be used as effective lab experiments that could give the students a hands-on experience using real world scenarios. This thesis presents an innovative web-based game developed for the demonstration of the driver-behavior at signalized intersections that can be used as a supplementary tool for the Transportation Engineering course. The game format is carefully designed to supplement the understanding of the class learning material through a fun environment. It was designed to be widely accessible through the internet and have an attractive user interface and was improved from the feedback obtained from the pilot study. The game is programmed on the .NET Framework using the Microsoft Visual C# as a core programming language, ASP to develop the web interface, and Microsoft Access as the databases for the program. The thesis also provides a methodological framework for collecting data about student engagement in a course and in particular presents the data collection procedure used in Transportation Engineering Course (CEE 4609). The collected data was analyzed to find the student engagement in the course after the introduction of the game. The thesis gives the conclusions drawn from the research with insights into possible drawbacks and scope for future improvements.
Institutional Counter-surveillance using a Critical Disability Studies Lens
Svyantek, Martina V. (Virginia Tech, 2021-05-27)
This study examines policy and procedure documents related to Disability at 3 U.S. institutions of higher education over a 25-year time frame. Policy and procedure documents are the foundation that govern how institutions "handle" Disability, outlining expectations and guidelines for providing services and establishing bureaucratic channels used to determine who has access to those services. This research employs a comparative case study mixed methods approach. The found documents and their online contexts are analyzed according to four qualities: findability, cohesion, consistency, and transparency. A document's findability refers to the ability of a user to locate the original document, and a document's cohesion, consistency, and transparency, refer to respectively where, what, and how these documents persist from their original creation date. As I collected these documents, I constructed comparative matrices to track these qualities within and across three different universities. The initial findability of documents demonstrates two key results: 1) during the overall 1990– 2015 time frame, there was a marked change in the availability of materials in a digital format, and 2) the emergence of a way to describe documents via the phrase "Does Not Exist." These materials definitively did not exist prior to a given time frame, but later versions of such documents included an earlier start date. Cohesion results indicate that the documents most likely to be presented in a single source were broadly usable to a large portion of the university population: the general student body. Consistency results address a major issue with the document search: while these materials were likely to exist, at each of these institutions and time frames (barring the DNE documents), they are very difficult to track down. Transparency across found, single-source documents was ubiquitous; if it could be found, it had searchable text. Beyond the findings of my document collection, I created two major products as a result of this dissertation work: key recommendations for different stakeholder groups and a curated exhibit of VT-specific materials collected for this study.
Motivating Students in Game-Based Learning: The Importance of Instructor Teaching Practices
Morelock, John Ray (Virginia Tech, 2018-11-29)
Game-based learning--using games to achieve learning objectives--represents a promising and increasingly popular means of progressing engineering education's decades-long goal of bringing more evidence-based, active learning pedagogy into the classroom. However, if game-based learning is to proliferate as a pedagogy, research on game-based teaching is critical to provide practical recommendations for implementation, making the pedagogy more accessible to instructors. However, reviews of game-based literature reveal that little work exists in the game-based teaching space, and what work exists models high-level teaching practices and archetypal roles, which often fail to pinpoint specific practices game-based instructors can use to be successful. Moreover, reviews of game-based learning literature more generally suggest that research on how to improve student motivation in game-based learning settings--an important variable for learning and a longstanding argument for the value of games in education--are lacking in both quantity and theoretical soundness. To redress these gaps, I conducted a primarily qualitative, multiple-case study of seven non-digital game-based learning activities in engineering with the goal of furthering game-based teaching research and providing practical recommendations to instructors when using games in their classrooms. Using the MUSIC Model of Motivation as a motivation framework and the Observation Protocol for Adaptive Learning as a framework for categorizing teaching practices, I interviewed instructors about how they expected their teaching practices to affect student motivation, and I interviewed these instructors' students about how they actually perceived their instructors' actions as affecting their motivation. By comparing instructor and student responses, I derived recommendations for game-based learning practice that are likely to have a high impact on student motivation, and condensed these recommendations into a four-phase framework of game-based teaching to bolster student motivation. I supplemented my interview data with observation data to construct detailed summaries of each case I studied. The recommendations I offer in my framework can serve as useful resources for instructors seeking to foray into game-based teaching practices or improve their existing game activities, especially in engineering. Moreover, my study provides a model for investigating game-based teaching practices and motivation in game-based learning using established theoretical frameworks in natural classroom settings.
The Motivation and Identity Development of Graduate Teaching Assistants in First-Year Engineering Programs
Kajfez, Rachel Louis (Virginia Tech, 2013-08-13)
Many engineering programs have a common content based first-year curriculum that all engineering students are required to take. These courses tend to be large in size, having multiple sections requiring the use of Teaching Assistants (TAs) who may be graduate students (GTAs) or undergraduate students (UTAs). The roles of TAs in first-year engineering courses vary from instructional staff to lab supervisors to graders, but despite their widespread use, little is known about the TAs' experiences. This study fills a gap in the literature by taking a participant centered approach to GTA motivation to teach and identity development as a teacher specifically in the context of first-year engineering programs (FYEPs). To guide this research, a combined motivation and identity framework was developed based on Self-Determination Theory (SDT) and Possible Selves Theory (PST). In the framework, PST serves as the foundation for the SDT constructs of competence, relatedness, and autonomy. The framework supports that the various constructs lead to increased motivation and identity development but that each experience through the process is based on one's own identity and views of themself in the future. This was studied through an exploratory sequential mixed methods design where 12 semi-structured interviews representing five different FYEPs served as the foundation for the development of a national survey completed by 33 GTAs representing seven different FYEPs. Priority was ultimately given to the qualitative strand, but mixing occurred throughout the study. The results indicate that there are seven factors that affect GTA motivation and identity and there are profiles, lenses, and filters can be used to understand GTAs' experiences in FYEPs. While each individual is unique, general trends among experiences were observed. Additionally based on the results, the framework was found to be an appropriate tool but that a slight modification was needed to better align the framework with GTA developmental trends. This research allows future research-based GTA training programs and appointments to be developed that specifically aim towards meeting the motivational and identity developmental needs of GTAs, ultimately improving the quality of higher education.
A Multiple-Case Study Exploring the Experiences of International Teaching Assistants in Engineering
Agrawal, Ashish (Virginia Tech, 2018-07-31)
Many international graduate students serve as teaching assistants at US universities. As teaching assistants, they carry out significant responsibilities such as leading lab sessions, grading student work, holding office hours, and proctoring exams. When these international teaching assistants (ITAs) cross national boundaries to teach at US universities, they may experience significant differences in the educational cultures. Teaching in a new educational culture offers ITAs both challenges and opportunities for growth. To better understand the experiences of this population within engineering, data were collected from seven engineering ITAs using a multiple-case study approach with each ITA representing a case. Data were collected in the form of weekly reflections and in-person interviews at the beginning, middle, and end of the semester, at an R1 university representative of national averages in terms of international graduate student population in the US. The participant pool represented diversity in the form of nationality, gender, prior teaching experience with the same course, and engineering discipline. Data were analyzed using both a priori codes and inductive coding emerging from the data, with particular attention given to experiences specific to engineering. Based on data analysis, codebooks were developed that operationalize ITAs' experiences and navigational strategies in the context of engineering. While illuminating the intersections of ITAs' teaching experiences with their international and GTA identities, the results point to the complexity and variations in participants' experiences based on various social and contextual factors such as gender, cultural background, prior exposure to the English language, prior engagement with the course material, and interaction with the teaching team. The results point to several contributions, and implications for engineering departments and universities, faculty, and ITAs to better engage ITAs in the process of undergraduate engineering education. In terms of contributions, this study uses intersectionality, a critical framework, which accounts for the complexity of engineering ITAs' experiences to provide systematic accounts of their experiences and navigational strategies while illuminating the nuances related to social, cultural, and disciplinary identities. Implications for the engineering departments and universities include creating an educational environment that values the cultural and linguistic diversity brought by ITAs, and collaborating with ITAs to organize training programs that help ITAs strengthen their communication, workload management, and intercultural skills; those for faculty include helping ITAs manage their teaching and research requirements by allowing for flexibility in ITAs' schedules, and treating ITAs as budding colleagues by using ITAs' existing pedagogical knowledge and scaffolding them when needed; those for ITAs include resisting the institutional pressure to "fit" into the US educational norms by using the pedagogical and cultural knowledge they bring from their home countries to better support student learning, and develop students' intercultural skills; and those for undergraduate students include engaging with ITAs to learn the engineering course content and simultaneously develop intercultural competence.
NLP in Engineering Education - Demonstrating the use of Natural Language Processing Techniques for Use in Engineering Education Classrooms and Research
Bhaduri, Sreyoshi (Virginia Tech, 2018-02-19)
Engineering Education is a developing field, with new research and ideas constantly emerging and contributing to the ever-evolving nature of this discipline. Textual data (such as publications, open-ended questions on student assignments, and interview transcripts) form an important means of dialogue between the various stakeholders of the engineering community. Analysis of textual data demands consumption of a lot of time and resources. As a result, researchers end up spending a lot of time and effort in analyzing such text repositories. While there is a lot to be gained through in-depth research analysis of text data, some educators or administrators could benefit from an automated system which could reveal trends and present broader overviews for given datasets in more time and resource efficient ways. Analyzing datasets using Natural Language Processing is one solution to this problem. The purpose of my doctoral research was two-pronged: first, to describe the current state of use of Natural Language Processing as it applies to the broader field of Education, and second, to demonstrate the use of Natural Language Processing techniques for two Engineering Education specific contexts of instruction and research respectively. Specifically, my research includes three manuscripts: (1) systematic review of existing publications on the use of Natural Language Processing in education research, (2) automated classification system for open-ended student responses to gauge metacognition levels in engineering classrooms, and (3) using insights from Natural Language Processing techniques to facilitate exploratory analysis of a large interview dataset led by a novice researcher. A common theme across the three tasks was to explore the use of Natural Language Processing techniques to enable the computer to extract meaningful information from textual data for Engineering Education related contexts. Results from my first manuscript suggested that researchers in the broader fields of Education used Natural Language Processing for a wide range of tasks, primarily serving to automate instruction in terms of creating content for examinations, automated grading or intelligent tutoring purposes. In manuscripts two and three I implemented some of the Natural Language Processing techniques such as Part-of-Speech tagging and tf-idf (text frequency-inverse document frequency) that were found (through my systematic review) to be used by researchers, to (a) develop an automated classification system for student responses to gauge their metacognitive levels and (b) conduct an exploratory novice led analysis of excerpts from interviews of students on career preparedness, respectively. Overall results of my research studies indicate that although the use of Natural Language Processing techniques in Engineering Education is not widespread, although such research endeavors could facilitate research and practice in our field. Particularly, this type of approach to textual data could be of use to practitioners in large engineering classrooms who are unable to devote large amounts of time to data analysis but would benefit from algorithmic systems that could quickly present a summary based on information processed from available text data.
