Race, Class And Gender In Engineering Education: A Quantitative Investigation Of First Year Enrollment, Canek Moises Luna Phillips

Open Access Dissertations

Research explanations for the disparity across both race and gender in engineering education has typically relied on a deficit model, whereby women and people of color lack the requisite knowledge or psychological characteristics that Whites and men have to become engineers in sufficient numbers. Instead of using a deficit model approach to explain gender and race disparity, in the three studies conducted for this dissertation, I approach gender and race disparity as the result of processes of segregation linked to the historic and on-going perpetuation of systemic sources of oppression in the United States. In the first study, I investigate …

Conceptual Understanding Of Threshold Concepts Of Electrical Phenomena: Mental Models Of Senior Undergraduates In Electrical Engineering, Mark T. Carnes

Open Access Dissertations

Every field of study has a set of domain-specific concepts that anyone who desires to work in that field must know and understand. Most students who pursue university degrees in engineering trust that their education is designed to provide them with this knowledge. But does it? In electrical engineering (EE), conceptual understanding of electrical phenomena has rarely been addressed. Even though the presumed goal of instructors and students alike is to learn the concepts of electrical phenomena well enough to be able to use the concepts to design useful things, it is difficult to determine whether this goal is being …

Thematic Analysis Of Influencers On Continuing Professional Learning Of Tenure Track Engineering Faculty As Assistant Professors At An Ru/Vh Institution, James Edwin Cawthorne

Open Access Dissertations

“Although the need for lifelong learning of professionals is stressed through university education, the patent differences between learning as a student, within a controlled framework focusing on accessible outcomes, and learning as a professional have not been clarified” (Webster-Wright, 2009, p. 708). Assistant professors are entry level professionals in academia who been prepared through their extensive education process to be lifelong learners and yet it is unknown how these assistant professors are engaging, or being engaged by others, in continuing their professional learning (CPL) for short-term and long-term success in academia as a career. This study aimed to understand who …

Learning The Language Of Academic Engineering: Sociocognitive Writing In Graduate Students, Catherine G. P. Berdanier

Open Access Dissertations

Although engineering graduate programs rarely require academic writing courses, the indicators of merit in academic engineering, such as journal publications, successful grants, and doctoral milestones (e.g. theses, dissertations) are based in effective written argumentation and disciplinary discourse. Further, graduate student attrition averages 57% across all disciplines, with some studies classifying up to 50% of these students as “ABD” (All But Dissertation.) In engineering disciplines specifically, graduate attrition rates across the U.S. average 36% (both Master’s and PhD students), according to the Council of Graduate Schools. The lack of socialization is generally noted as a main reason for graduate attrition, one …

A Standards-Based Grading Model To Predict Students' Success In A First-Year Engineering Course, Farshid Marbouti

Open Access Dissertations

Using predictive modeling methods, it is possible to identify at-risk students early in the semester and inform both the instructors and the students. While some universities have started to use standards-based grading, which has educational advantages over common score-based grading, at–risk prediction models have not been adapted to reap the benefits of standards-based grading. In this study, seven prediction models were compared to identify at-risk students in a course that used standards-based grading. When identifying at-risk students, it is important to minimize false negative (i.e., type II) errors while not increasing false positive (i.e., type I) errors significantly. To increase …

A Consensus On The Definition And Knowledge Base For Computer Graphics, Michael Alden Roller

Open Access Dissertations

Despite several decades of historical innovation, measurable impacts, and multiple specializations the existing knowledge base for Computer Graphics (CG) lacks consensus, and numerous definitions for it have been published based on distinct contexts. Disagreement among post-secondary academics has divided CG programs into three contextual areas that emphasize different topics. This division has resulted in the decontextualization of CG education, and CG programs now face several challenges in meeting the needs of industry. Employing the Delphi Method, this investigation explored the perceptions among post-secondary educators and industry professionals about the definition of CG and how it is identified in terms of …

Understanding How Adults Approach Technological Challenges: A Sequential Mixed Methods Research, Mariana Tafur Arciniegas

Open Access Dissertations

People from all backgrounds engage with technology in their everyday lives. There is, however, a gap in the public's understanding of technology and limited research on how engineers and non-engineers approach technological challenges. Prior studies have focused on the public's understanding of technology but limited research has been conducted on how people deal with technological challenges as part of their everyday lives. Studying how individuals with non-STEM backgrounds engage with technology will contribute a more comprehensive understanding of strategies for closing the technological literacy gap. Taking into account that technology developments rapidly occur, lifelong learning skills are another critical dimension …

Suitability Of Commercial Certification Assessments For Film And Video Editing Courses, Bobby L Chastain

Open Access Dissertations

A study on the microstructure development of as-cast Cu-Mn alloys based around the congruent minimum at 34.6 wt % Mn and 873 °C was performed. Initially, this was to evaluate the alloy as an alternative to wide freezing range Pb and Sn bronzes that are plagued with porosity. The shallow minimum and associated narrow freezing ranges around the congruent point result in a completely cellular (non-dendritic) solidification morphology for a composition range ~3 wt % Mn about the congruent composition (C _c). The degree of cellular solidification was found to depend on the mold material. Increased mold conductivity lead …

Undergraduate Engineering Students' Experiences Of Interdisciplinary Learning: A Phenomenographic Perspective, Ming-Chien Hsu

Open Access Dissertations

Engineers are expected to work with people with different disciplinary knowledge to solve real-world problems that are inherently complex, which is one of the reasons that interdisciplinary learning has become a common pedagogical practice in engineering education. However, empirical evidence on the impact of interdisciplinary learning on undergraduates is lacking. Regardless of the differences in the scope of methods used to assess interdisciplinary learning, frameworks of interdisciplinary learning are imperative for developing attainable outcomes as well as interpreting assessment data. Existing models of interdisciplinary learning have been either conceptual or based on research faculty members' experiences rather than empirical data. …

Quality By Association Across North-South Divides: United States Accreditation Of Mexican Institutions Of Higher Education, Gerardo Blanco Ramírez

Open Access Dissertations

Institutional accreditation in higher education presents a dual reality: Accreditation is intended to hold colleges and universities accountable through external evaluation and, at the same time, accreditation constitutes an opportunity for higher education leaders to assess, improve, and communicate the quality of their undertakings. In an increasingly global field of higher education, quality practices become diffused across national boundaries. U.S. institutional accreditation is one of the quality practices embraced around the world; institutions of higher education, particularly in the Global South, aspire to obtain U.S. institutional accreditation. While important, this phenomenon has gone largely unexamined in research. This study follows …
