Data-Wisdom As A Framework For Building Data Literacy, Rita Swartzentruber

Masters Theses

In a world where “big-data” rules, the need for data literate citizens is critical. Not only do we need citizens who can read data, but also citizens who are critical of data practices that perpetuate racist practices. One potential answer for this call is to create “data-wise” citizens. The purpose of this design-based research study was to explore how secondary and post-secondary students can develop data-wisdom through the analysis of three data-inspired artistic data visualizations. This study examined the growth of data-wisdom in participants, the development of classroom norms, and the increase in positive perceptions of mathematics in participants. Data …

Natural, Experimental, And Educational Explorations Of The Interiors Of Terrestrial Planetary Bodies, Nadine L. Grambling

Doctoral Dissertations

Planetary interiors are enigmatic, inaccessible, and vital to the processes that have formed the rocks we see on the surface of bodies in the inner Solar System today. Based on geophysical explorations of the Moon and Earth, along with information gleaned from rocks at the surface today, there is understanding of the basic structure and processes at depth. Using a combination of natural samples and experimental studies, we attempt to learn more about the physical conditions beneath the surface, and their effect on material properties and tectonics processes in the mantle.

Out Of School Time Science Programs: Examining A Program’S Impacts On The Science Identities Of Middle School Female Participants, Elizabeth Ripley Mactavish

Doctoral Dissertations

Science education reform efforts emphasize teaching science for all Americans, and identify scientific literacy as the principle goal of science education (American Association for the Advancement of Science [AAAS], 1993; National Research Council [NRC], 1996). Despite the goal of scientific literacy, some students, especially females and minorities, consider science irrelevant to their personal interests or career goals. Additionally, research pinpoints middle school as a period when female students begin to lose interest in science (Farenga, 1999; Hill et al., 2010).

Decades of research have documented the gender achievement gap, yet little research has been focused on the science identity gap …

Classroom Response System Integration In A Distance-Learning Introductory High School Physics Course, Alexander T. Pegram

Masters Theses

Tennessee ranks among the lowest states in terms of high school physics availability. This fact is compounded in rural areas by limited enrollment and a lack of accredited physics teachers. A distance-learning physics course was established between the University of Tennessee Knoxville and Morristown West High School in order to offer an introductory physics course in a school with no accredited physics teacher. Because classroom response systems have been shown to increase interactivity and discussion in physics courses, leading to better learning gains, the course was taught via live video-conferencing with the integration of a classroom response system.

Elementary And Secondary Science Teachers Negotiation Of Controversial Science Content: The Relationships Among Prior Conception Appropriation, Thinking Disposition, And Learning About Geologic Time, James Harold Roberson

Doctoral Dissertations

A major component of the values people place on science and their attitude toward it is their openness to new ideas or overall open-mindedness. An individual’s values and attitudes become integrally connected to their prior knowledge and conceptions regarding science and science content. Sometimes the nature of a natural phenomenon and the scientific explanation for the phenomenon is controversial. A controversial scientific concept is one that evokes emotion and forces individuals to assess the values associated with this content and make assessments of their attitudes toward it. This is especially true during learning. The purpose of this study was to …

Professionalism: What Is It And Are We Teaching For It?, Brian K Tate

Doctoral Dissertations

With rising accountability standards and the need for content specialists within education, the qualifications of mathematics teachers have become increasingly scrutinized. For over three decades, within the parameters of educational reform, the need for the professionalization of teaching has reoccurred (Carnegie Task Force, 1986). When examining the nature of teacher professionalism, no concise definition within the educational community exists (Noddings, 1992). The purpose of this study was to take characteristics defined by the medical and law fields and use them to develop a definition of professionalism within mathematics education. Once a clear set of characteristics was identified, the study then …
