The main topics of this dissertation are: 1) the development and discussion of a new molecular balance for measuring alkyl-alkyl interactions in a wide array of organic solvents, 2) the development of linear solvation energy relationships between solvent interaction parameters and solvent accessible surface area (SASA) in CH-arene interactions,…

Despite decades of research, NOS is still rarely explicitly and accurately taught in K-12 schools (Abd-El-Khalick & Lederman, 2023). Teachers often address NOS ineffectively as a result of inadequate knowledge of NOS and science content (Wahbeh & Abd-El-Khalick, 2014) as well as NOS pedagogy (Hanuscin et al., 2011). A variety of contextual…

Integrating science and engineering has become a focal point for current research in science and STEM educational fields. Infusing engineering design as an application of scientific principles is beneficial, as it demonstrates an authentic, real-world application and allows for not only student engagement and enthusiasm, but also an avenue to…

This study investigated evidence of how students' mental models of fundamental kinematic relations evolved (i.e., developed cognitively over time) as observed during an introductory course in calculus-based classical mechanics. The core of the curriculum is based on a claim known as Galileo's principle of relativity. The course material comprised…

Scholars over the past few years have drawn attention to the enormous potential role historical stories can play in promoting student understanding of issues associated with the nature of science (NOS). Such stories, often referred to as "historical narratives," are thought to do so by providing a rich historical context within which…

As the adoption rate of the Next Generation Science Standards (NGSS) continues to rise in the United States, there is an increasing need for the development of high-quality instructional materials that reflect NGSS and effectively prepare teachers for its implementation. The NGSS aim to foster an understanding of three interconnected dimensions in…

This study investigated how the figured world of the RET, and other figured worlds of science that teacher's experience, impacted their conceptions around the nature of science and their identities in science and as science teachers. The main premise behind RET programs is that by partnering science teachers with scientists as mentors, science…

Nature of Scientific Knowledge (NOSK) and Nature of Scientific Inquiry (NOSI) are important components of scientific literacy and important educational objectives in science education. Recent literature theorizes that understanding both NOSK and NOSI increases students' understanding of science content knowledge. However, this assumption has yet…

Over the past several decades, science education reforms have called for students to develop appropriate views of the nature of science and have a comprehensive understanding of subject matter. Additionally, education research has demonstrated that teachers must have appropriate views of the nature of science and strong content knowledge as…

Spatio-temporal processes are ubiquitous and prevalent across disciplines. Understanding the mechanisms underlying processes and integrating this information into models is of great interest, as it can improve forecasting accuracy and align with scientific motivation. Examples of such models include Partial Differential Equation (PDE) Models or…

The purpose of this mixed-method study is to determine the effect of integrating Engineering design on high school students' scientific reasoning and science achievement. Thirteen eleventh-grade students participated in this eight-week long study. The intervention engaged students in the Engineering design of a functional Dialysis model. Students…

Teaching science through inquiry-based methodologies has been advocated by several governmental and professional organizations (National Research Council [NRC], 2000; NGSS Lead States, 2013); however, their use is not widespread. Why is this? What science teachers do in their classrooms is shaped by their beliefs, especially their beliefs about…

The subject of chemistry is a cornerstone of high school science programs and a conceptual understanding of chemical equilibria and Le Chatelier's Principle continues to be both a fundamental and paradoxically difficult subject for educators and students. This study evaluated the effectiveness of a prototype immersive virtual reality environment.…

Competency levels around scientific literacy for high school students in the United States are insufficient for students' future ability to be competent consumers and voters. The purpose of this action research study was to explore how students were being exposed to scientific literacy concepts in high school science courses in the United States.…

The history of education in the United States has been a contentious one. This holds true for science education in Georgia. Throughout history, there has been much debate on what should be taught and how it should be taught. There have been many influences on education including politics, economics, religion, and immigration. This multi-method…
