The Effect Of An Historical Geology Course On Students’ Attitudes Towards Science And Their Knowledge Of Deep Time As A Threshold To Their Knowledge Of Evolution, Allan Nolan

Dissertations

In America there exists a conflict between a small group of its citizens and the concept of evolution. Researchers have studied this conflict and the ways in which teachers might approach educational methodologies that not only address evolution in a sensitive manner, but also remain legally acceptable.

This research was designed to address teaching evolution in the context of deep time – the concept that time is vast and that geology and biology operate in a timescale of hundreds of millions to billions of years. In previous peer-reviewed works, it has been stated that deep time acts as a threshold …

Tangible Teaching: The Effect Of Physical Modeling On Community College Students’ Understanding Of Conservation Of Matter, Erick T. Moffett

Dissertations

Students’ weak understanding of conservation of matter is well documented; however, there is a paucity of research that provides science educators with actual examples of empirically proven curricula employing physical modeling that can be used in the chemistry classroom to teach this fundamental concept. An intervention (three sequential physical modeling activities) was developed and evaluated. The intervention was administered to two sections of a General Chemistry I course at a community college in the southeastern United States, and pre-test/post-test data using a published instrument were collected to evaluate the physical model’s effectiveness in developing students’ understanding of conservation of matter …

A Model For Propagating Educational Innovations In Higher Stem Education: A Grounded Theory Study Of Successfully Propagated Innovations, Raina Khatri

Dissertations

A critical problem in undergraduate science, technology, engineering, and mathematics (STEM) education is the slow uptake of innovative teaching strategies and materials. Developments from the STEM education research community can be shown to improve learning and retention outcomes, but the majority of new teaching strategies go unused by instructors. This problem is increasingly acknowledged by funding agencies such as the National Science Foundation, which now calls for “transferability and propagation” to be addressed throughout a project’s lifetime in the request for proposals. However, few publications synthesize what is known about propagating innovations into usable, actionable recommendations for developers in the …

Impacts Of Cohort Membership On Teacher Candidates In An Alternative Certification Program, Katherine Eaton

Dissertations

Post baccalaureate teacher education programs are an effective way to increase the teaching pool with candidates who are content experts (Beijaard et al. 2004; Brantlinger, A., & Smith, B., 2013; Zeichner, K. M., & Schulte, A. K., 2001; Schultz, K., & Ravitch, S. M. 2013; Humphrey et al., 2008). Many of these programs utilize a cohort model design where students progress through the program together as a group (Maher, M. A. 2005; Jorissen, K. T., 2002; Ross et al., 2006; Mandzuk, D. et al., 2005). In his book, Deep Knowledge (2013), Larkin describes the complex nature of preparing candidates for …

This intervention should begin as early as …

Ldentifying And Characterizing Cognitive Factors Significant To Practicing And Learning Meteorology, Peggy M. Mcneal

Dissertations

To see the world as a meteorologist, one must understand and interpret atmospheric processes through representations depicted on two-dimensional weather charts and maps that encode large amounts of spatial and numerical data. This is a cognitively demanding and spatially challenging task, especially for students with burgeoning levels of meteorology knowledge, who lack the expertise of practiced meteorologists that read such charts and maps with ease. With little prior work informing meteorology and meteorology education through a cognitive science lens, this study surveys the literature and follows models of discipline-based education and cognitive science research to identify the discrete intelligence factors …

Processing Motion: Using Code To Teach Newtonian Physics, M. Ryan Massey

Dissertations

Prior to instruction, students often possess a common-sense view of motion, which is inconsistent with Newtonian physics. Effective physics lessons therefore involve conceptual change. To provide a theoretical explanation for concepts and how they change, the triangulation model brings together key attributes of prototypes, exemplars, theories, Bayesian learning, ontological categories, and the causal model theory. The triangulation model provides a theoretical rationale for why coding is a viable method for physics instruction. As an experiment, thirty-two adolescent students participated in summer coding academies to learn how to design Newtonian simulations. Conceptual and attitudinal data was collected using the Force Concept …

Employing Multivariate Logistic Regression Analysis To Better Understand The Relationship Between Individuals’ Anthropogenic Climate Change Acceptance And Belief In Anti-Climate Change Dissenter Messages, Andrew Phillip Keller Bentley

Dissertations

Organized climate change dissention groups spend a considerable amount of time and energy developing messages designed to convince the public that anthropogenic climate change is neither a reality nor a threat. These messages work against the efforts of climate educators and can be divided into two categories; messages that provide alternative explanations for warming, or messages that attack the work of scientists studying anthropogenic climate change. There has been a lack of research regarding any correlation between individuals’ agreement with these messages and their rejection of anthropogenic climate change. Establishing a correlation would be an indication that educators should take …

Effects Of Historical Story Telling On Student Understanding Of Nos And Mendelian Genetics, Cody Tyler Williams

Dissertations

Science education researchers have long advocated the central role of the nature of science (NOS) for our understanding of scientific literacy. NOS is often interpreted narrowly to refer to a host of epistemological claims associated with the process of science and the limitations of scientific knowledge. Despite its importance, practitioners and researchers alike acknowledge that students have difficulty learning NOS and that this in part reflects how difficult it is to teach. Many teachers are uncomfortable with taking time away from traditional science content instruction. One promising method for teaching NOS and science content involves an explicit and reflective approach …

Teachers’ Perceptions Of Educational Games That Keep Score Of Cooperative Performances, Theodore Alden Wohlfarth

Dissertations

The scoring systems used in traditional sports and games are founded on the zero-sum premise that players are on opposite sides and one side can win only if the other side loses. These scoring systems may be effective at nurturing zero-sum mindsets and providing data for assessing performance in win-lose relationships. If so, games that use different scoring systems can be used to facilitate the development of collaborative mindsets, nurture win-win skills between diverse groups, and enable objective self-assessment of performances in non-zero-sum events when engaging with those on “other sides.” Although economic game theory has rich reservoirs of research …

ACT scores are widely used to predict outcomes in coursework and serve as placement guidelines for college level courses such as college algebra. Due to a changing college environment, the appropriateness of these placement decisions takes on a new, more critical light. Given the rate of success for current predictions in college algebra, and the resulting consequences for misplacement, this study examines the predictive potential of the ACT scores through the examination of non-linear variables and a metaphorically chaotic interpretational lens.

The literature base for this study reveals, almost to exclusion, the use of linear models for the prediction of …

Analysis Of Professors’ Perceptions Towards Institutional Redevelopment Of Brownfield Sites In Alabama, Berkley Nathaniel King Jr.

Dissertations

This study was conducted to analyze professors’ perceptions on the institutional redevelopment of brownfield sites into usable greenspaces. The U.S. Environmental Protection Agency (2011) refers to brownfields as sites, (either facility/land) under public law § 107-118 (H.R. 2869), which are contaminated with a substance that is classified as a hazard or a pollutant. Usable greenspaces, however, are open spaces or any open piece of land that is undeveloped, has no buildings or other built structures, and is accessible to the public (EPA, 2015).

Open green spaces provide recreational areas for residents and help to enhance the beauty and environmental quality …
