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 …

From Mechanic To Designer: Evolving Perceptions Of Elementary Students Over Three Years Of Engineering Instruction, Anastasia M. Rynearson

Open Access Dissertations

Due in part to increasing state standards that require engineering in K-12 curricula and the Next Generation Science Standards’ incorporation of engineering outcomes, inclusion of engineering into elementary classrooms is on the rise. Teacher development and experiences in learning about and implementing engineering have been studied, but elementary students’ experiences when learning about engineering have not been explored.

The purpose of this study is to address the question: How do elementary students’ knowledge of, attitudes toward, and overall conceptions of engineering evolve over three years of engineering instruction?

This study follows seven elementary school students through three years of engineering …

Development Of First-Year Engineering Teams' Mathematical Models Through Linked Modeling And Simulation Projects, Kelsey Joy Rodgers

Open Access Dissertations

The development and use of mathematical models and simulations underlies much of the work of engineers. Mathematical models describe a situation or system through mathematics, quantification, and pattern identification. Simulations enable users to interact with models through manipulation of input variables and visualization of model outputs. Although modeling skills are fundamental, they are rarely explicitly taught in engineering. Model-eliciting activities (MEAs) represent a pedagogical approach used in engineering to teach students mathematical modeling skills through the development of a model to solve an authentic problem.

This study is an investigation into the impact of linking a MEA and a simulation-building …

A Phenomenographic Study Of The Ability To Address Complex Socio-Technical Systems Via Variation Theory, John A. Mendoza Garcia

Open Access Dissertations

Sometimes engineers fail when addressing the inherent complexity of socio-technical systems because they lack the ability to address the complexity of socio-technical systems. Teaching undergraduate engineering students how to address complex socio-technical systems, has been an educational endeavor at different levels ranging from kindergarten to post-graduate education. The literature presents different pedagogical strategies and content to reach this goal. However, there are no existing empirically-based assessments guided by a learning theory. This may be because at the same time explanations of how the skill is developed are scarce.

My study bridges this gap, and I propose a developmental path for …

Examining Teachers' Perspectives On An Implementation Of Elementary Engineering Teacher Professional Development, Nikki Kim Boots

Open Access Dissertations

The emphasis on engaging young learners in science, technology, engineering, and math (STEM) professions is driving calls for educational reform. One movement that is gaining momentum is exposing K-12 learners to engineering. With the advent of the Next Generation Science Standards (2012b), engineering is being more formally integrated into standards for the K-12 level. As a result, in-service elementary teachers will need to become familiar with the core concepts of engineering to effectively teach aspects of the subject in their classrooms. Elementary engineering teacher professional development (EETPD) has been identified as a method to disseminate engineering content knowledge to elementary …

Student Success: Approaches To Modeling Student Matriculation And Retention, Jien-Jou Lin

Open Access Dissertations

Every year a group of graduates from high schools enter the engineering programs across this country with remarkable academic record. However, as reported in numerous studies, the number of students switching out of engineering majors continues to be an important issue. Previous studies have suggested various factors as predictors for student retention in engineering. To assist the engineering students with timely advising early in their program, an effective prediction model of matriculation and retention in engineering that use available student data are highly desirable.

In the first part of this work, the author developed new prediction models of student retention …
