The dissertation is composed of two sections. The first section is composed of chapters one, two, and three and describes the study of macrocyclic [beta]-hairpin peptides derived from [beta]-sheet peptides. The second section is composed of chapters four and five and discusses the curricular innovations made to support the remote instruction of an…

The creation and evaluation of known evolutionary histories and the implementation of student investigatory experiences on evolution are difficult endeavors that have only recently been feasible. The research presented in this dissertation is related in their shared use of digital evolution with Avidians as a model study system, both to conduct…

Recently, there have been many calls for an increase in instruction on the nature of science (NOS) in schools (i.e. NRC, 1996; NGSS Lead States, 2013). These calls recognize the importance of this topic at all levels of science education, but there is little guidance in terms of how to address it effectively in curricula. Similarly, there have…

This is a study of student engagement with computational labs in Calculus 2. The labs task students with using MATLAB to investigate contexts such as rocket science, disease modeling, and market economics forecasting by modifying and executing provided code, guided by questions that have students report the results of their simulations or…

The dissertation is composed of two main parts. The first half describes efforts to study amyloid peptides using macrocyclic peptide model systems, and the potential deleterious effects of uronium peptide coupling agents on human health. The second half focuses on my experience in chemistry teaching and the chemical education research I conducted.…

The potential for humans to influence Earth's climate was theorized by scientists like Svante Arrhenius as early as 1896. Yet, as late as 2020, political leaders, like the former President Donald Trump, and the people who follow them continue to doubt the possibility. With growing scientific evidence that human activities are degrading our…

This Educational Leadership Portfolio (ELP) addresses the issue related to children's screen time and indoor sedentary behavior. Research shows that young children need to have time outside in nature to ensure holistic development in the twenty-first century. The overarching goal of this work is to reduce the extent of children's indoor sedentary…

Climate change and the resulting and related environmental and humanitarian outcomes are some of the fundamental challenges of the 21st century. Green chemistry, a relatively recent addition to the chemistry family, aims to reframe chemistry so that chemistry ethically and responsibly attends to its own environmental and human health impacts and…

The primary purpose of this study was to examine the perceptions that Alabama funeral service licensees had towards their academic preparation for entry-level funeral service careers in a professional field that was changing. More specifically, this study identified and examined specific learning objectives within the American Board of Funeral…

We designed and implemented curriculum intended to be used by students in an algebra-based introductory physics laboratory course. Our curricular goal was to foster, through observations in the lab, a coherent framework in students' understanding of general principles presented in the introductory mechanics course, while addressing known student…

The field of training has been changing rapidly due to advances in technology such as videogame-based adaptive training. Videogame-based adaptive training has provided flexibility and adaptability for training in cost-effective ways. Although this method of training may have many benefits for the trainee, current research has not kept up to pace…

Reform in mathematics instruction at the college level has been slow to arrive (Dossey, Halvorson, & McCrone, 2008), and many institutions of higher learning still follow the calculus model, while fewer and fewer students need calculus for their chosen areas of study (Ganter & Barker, 2003). Instead, mathematics that is applicable and transferable…

The purpose of this study was to examine efficacious teaching-learning strategies that community college stakeholders employ that enhance surgical technology student outcomes. Knowles's adult learning theory, constructivist theory, and appreciative inquiry served as the theoretical foundation for this study. Discovering effective aspects and…

Mechatronic systems that couple mechanical and electrical systems with the help of computer control are forcing a paradigm shift in the design, manufacture, and implementation of mechanical devices. The inherently interdisciplinary nature of these systems generates exciting new opportunities for developing a hands-on, inventive, and…

This study investigated the lived experiences of a group of students and their teacher as they negotiated learning and teaching during a sixth-grade exploratory music technology course taught in a music technology lab. Taking a qualitative and naturalistic approach, I sought to understand the challenges, issues, and successes experienced by the…
