Chasing Polys: Interdisciplinary Affinity And Its Connection To Physics Identity, Tyler Scott

All Dissertations

This research is based on two motivations that merge by means of the frameworks of interdisciplinary affinity and physics identity. First, a goal of education is to develop interdisciplinary abilities in students' thinking and work. But an often ignored factor is students interests and beliefs about being interdisciplinary. Thus, this work develops and uses a framework called interdisciplinary affinity. It encompasses students interests in making connections across disciplines and their beliefs about their abilities to make those connections. The second motivation of this research is to better understand how to engage more students with physics. Physics identity describes how a …

Examining Employees' Perceptions Of Energy Conservation Behaviors In Office Settings, Michele Belmont Halsell

Graduate Theses and Dissertations

The estimates for potential energy and greenhouse gas (GHG) savings in office buildings are significant. Reports show that energy wasting behavior in office buildings such as computers being left on at night and on weekends result in billions of dollars lost annually and GHG's being emitted needlessly. The estimated potential for energy savings ranges from 20 to 50 percent. Despite the potential for significant energy savings, a review of the literature revealed that there are relatively few studies of energy conservation interventions in office buildings. Most of the research on energy conservation has been done in households. There is agreement …

Inferential Procedures For Dominance Analysis Measures In Multiple Regression, Shuwen Tang

Theses and Dissertations

In order to better interpret a selected multiple regression model, researchers are often interested in whether a predictor is significantly more important than another or not. This study investigates the performance of the Normal-Theory based (asymptotic) confidence interval and bootstrap confidence intervals for predictors' dominance relationships using both normal and non-normal data. The results show that asymptotic confidence interval method is adequate to make inferences for comparing two general dominance measures when the distribution is multivariate normal or slightly non-normal and when the effect size is no less than 0.15 and the sample size is at least 100. However, the …

Selva Simbólica Selva Simbiótica Apuntes Para Una Ecocritica Latinoamericana, Liza Pamela Rosas-Bustos

Dissertations, Theses, and Capstone Projects

This dissertation focuses on Latin America's selvatic territories. It argues for prevailing ecological principles as revealed in the selected works of three twentieth-century Latin American story-writers and poets. They portray rainforests as multisensorial lands that encompass bewildering events from which a principle of local authority emerges. This analysis is based on Francisco Coloane's short stories "Tierra del Fuego" and "Cabo de Hornos," Rosario Castellanos'Balún Canán, and Luis Sepúlveda's Un viejo que leía novelas de amor. Such phenomenology is also present on the environmental poetics from Marosa di Giorgio, Cecilia Vicuña, and Leonel Lienlaf linked to emotions of fear, urgency, …

Designing For Statistical Reasoning And Thinking In A Technology-Enhanced Learning Environment, Wendy Tu

CCE Theses and Dissertations

Difficulties in learning and understanding statistics in college education have led to a reform movement in statistics education in the early 1990s. Although much work has been done, there is more work that needs to be done in statistics education. The progress depends on how well the educators bring interesting real-life data into the classroom.

The goal was to understand how course design based on First Principles of Instruction could facilitate tertiary-level students' conceptual understanding when learning introductory statistics in a technology-enhanced learning environment. An embedded single descriptive case design was employed to investigate how integrating technology and real data …

Assistive Technologies Used By Students With Asperger’S Syndrome To Improve Performance In The General Education Classroom, Sara (Beth) Cardwell Foreman

CCE Theses and Dissertations

The No Child Left Behind Act requires all students; regardless of poverty level, learning disability, limited English proficiency, or racial/ethnic origins; to be in general education classrooms meeting high standards of proficiency in reading/language arts and mathematics by 2013-14. Meeting high standards of proficiency in a general education classroom is particularly challenging for students diagnosed with pervasive developmental disorders, such as Asperger's syndrome. Limited interests, inflexible language, and social skills deficits without a history of cognitive or language delays before the age of three characterize the disorder. Other symptoms, such as clumsiness, unusual sensory reactions, and talk in unusual ways …

Examining The Process Of Identification In The Mathematics Classroom And The Role Of Students’ Academic Communities, Richard J. Robinson

Doctoral Dissertations

The primary purpose of this research was to provide insight into the identities students develop as they interact in a high school mathematics classroom. A normative divide developed which eventually split the classroom into two distinct academic factions: those who resisted the emerging local definition of what it meant to do mathematics and those who did not resist (i.e. complied or identified). A secondary purpose of this research was to understand the role of students’ academic communities in mathematics identity development. Student narratives helped uncover mathematical spaces outside the classroom that each developed their own unique definition of what it …

The Experiences Of Women In Post Graduate Physics And Astronomy Programs: The Roles Of Support, Career Goals, And Gendered Experiences, Ramón S. Barthelemy

Dissertations

In physics and astronomy the low representation of women is obvious at every stage of the educational pathway from undergraduate students to full professors. These low numbers perpetuate themselves by failing to create new mentors to foster the next generation of women. Women and men also have different experiences as they traverse into physics and astronomy careers. Women often experience chilly climates, discrimination, and challenges coordinating the demands of young families with their careers. In the literature exploring this topic, little focus is put on the experiences of women graduate students in physics and no focus is put on women …

A Computer Learning Environment For Novice Java Programmers That Supports Cognitive Load Reducing Adaptations And Dynamic Visualizations Of Computer Memory, James Stephen Williams

Theses and Dissertations

Learning to program a computer is difficult for many. The Learning Edge Momentum hypothesis suggests that the difficulty may be due to the tightly integrated nature of programming concepts and adapting the way curriculum is offered may have a significant influence on the outcomes. We investigate applying cognitive load reducing methods to instruction of the introductory programming concepts of declaration, assignment and sequence, using a new learning environment that an instructor can adapt for a specific example or that a student can personalize for amount and modality of content provided. Our study has three learning surveys. Each learning survey has …

Student Application Of The Fundamental Theorem Of Calculus With Graphical Representations In Mathematics And Physics, Rabindra R. Bajracharya

Electronic Theses and Dissertations

One mathematical concept frequently applied in physics is the Fundamental Theorem of Calculus (FTC). Mathematics education research on student understanding of the FTC indicates student difficulties with the FTC. Similarly, a few studies in physics education have implicitly indicated student difficulties with various facets of the FTC, such as with the definite integral and the area under the curve representation, in physics contexts. There has been no research on how students apply the FTC in graphically-based physics questions.

This study investigated student understanding of the FTC and its application to graphically-based problems. Our interest spans several aspects of the FTC: …

Prediction Of Time-To-Graduation For Stem Hispanic Undergraduate Students, Gejun Zhu

Theses and Dissertations - UTB/UTPA

In this thesis, we study the time-to-graduation problem for STEM Hispanic undergraduate students. The response, time-to-graduation, was treated in two different ways: as a binary variable with graduated (by the 6th year) and not-graduated values, and as an ordinal variable with values year-4, year-5, year-6, and not-graduate. Mathematics education plays critical role in students’ timely graduation, especially for STEM students. We used students records data obtained from The University of Texas-Pan American to illustrate how mathematics background factors (including SAT math score, ACT math score, TASP math score) and mathematics performance variables (including mathematics GPA, number of dropped mathematics courses, …
