The Big Bend region of Trans-Pecos Texas preserves a rich record of Rio Grande rifting and Laramide-age contraction that provide intrigue to national and state park visitors and field trips for undergraduate geology students. Despite its well-exposed geologic record, the Big Bend region remains an underutilized natural laboratory for studying…

The purpose of this research was to explore the coherence and effectiveness of an assessment approach that combined principles of cognitive-based assessment, performance assessment, and the Next Generation Science Standards. By drawing on research on learning progressions and cognition in geoscience to design, implement, and analyze an Earth…

Background: This dissertation examines the pervasive influence of the white and colonial imaginary in shaping educational narratives that promote neoliberal success and capitalism, impacting the minds of successive generations. Contemporary youth perceive these narratives as detrimental, contributing to racial violence, climate-induced…

Spatial skills, which represent the ability to mentally manipulate objects (Schneider & McGrew, 2012; Atit et al., 2020) have been shown to be correlated with entrance, persistence and success in STEM (Shea et al., 2001; Wai et al., 2009). Specifically, these skills have been shown to be necessary to geologists and geoscientists (Hegarty,…

Over the years, there has been an underrepresentation of Black males in the Geotechnical Engineering field in the United States. White men have dominated the Geotechnical Engineering sector, and that practice continues today. According to Fatourou et al. (2019), the disparity of Blacks in the engineering workforce is a universal matter that speaks…

Ethnogeology is the scientific study of human relationships with the Earth as a system, typically conducted within the context of a specific culture. Indigenous or historically resident people may perceive local places differently from outside observers trained in the Western tradition. Ethnogeologic knowledge includes traditional indigenous…

In-person field education through exploration is fundamental in geoscience, but equal access is limited by time, cost, safety, distance, physical ability, and instructor variability. Technology advances allow students to explore pedagogically rich but inaccessible places through virtual field trips (VFTs). Studies show that VFTs result in…

The studies in this dissertation were conducted to better understand how to measure students' use of multiple representations in introductory science courses by expanding the possibilities of a variable representation assessment (VRA). The VRA is a computer-based assessment originally designed to measure general chemistry students' use of…

The study consisted of three articles. Article one aimed to determine if there were any significant difference in science graduate students' (SGSs') conceptions of the "consensus tenets" of the nature of science (NOS) with respect to demographic factors -- the SGSs' academic and research characteristics. The participants were SGSs from…

Information seeking is "a conscious effort to acquire information in response to a need or gap" in your knowledge (Case, 2007, p. 5). In the geosciences, physical samples such as cores, cuttings, fossils, and rocks are primary sources of information; they represent "the foundation of basic and applied geoscience research and…

Environmental stewardship is an underlying theme in outdoor education (OE) and environmental education (EE), but maintaining natural areas in a sustainable balance between conservation and preservation requires knowledge about how natural areas respond to anthropogenic disturbance. My five-part study investigated the effects of disturbance on…

Learning progressions are the latest tool to understand the ways science learning occurs and they underlie the structure and framework of the "Next Generation Science Standards". Prior research indicated a variety of ways to develop and validate learning progressions and learning progression's general positive impact on students' science…

This dissertation is the product of several individual multi-disciplinary investigations that cover a variety of topics in mathematics, physics, geology, and geoscience education. The first chapter formulates a better understanding of the timings, magma source, and relationships between dikes and associated magmatic bodies of the Red Bluff…

By the end of the nineteenth century, the momentum for the idea of a more practical education better suited to life in a modern, technological world brought the first educational reform movements in the nation. Concurrent reform efforts at the state and national levels influenced both the historical development of Earth science education and the…

The timing and processes of development of the high topography and high relief of the southern Rocky Mountains of Wyoming, Colorado and New Mexico has been controversial for over a hundred years. This study applies several different methodologies towards understanding the timing and relative importance of the events that uplifted and shaped the…
