The concept of integration appears in many different scientific fields, and students' understanding of and ability to use the definite integral in applications is important to success in their STEM (science, technology, engineering, and mathematics) classes. One of the first types of application problems that students encounter is finding the…

This qualitative, instrumental case study examined how a mentor inquiry community can serve as a space for mentors to articulate their knowledge and what about the inquiry community, its characteristics, might harm or help that development. Using Design-Based Research as the methodology, a mentor inquiry community, composed of three…

Computers infiltrate almost every aspect of our lives, including our homes and cars. For work, education, or personal fulfillment, computing has increased dramatically. The need for an educated workforce is expanding as technology devices become smaller, faster, and more powerful. We can teach students how to use math, logic, and computational…

Human health and wellbeing are rooted in the environment, and thus are threatened by environmental degradation. The healthcare industry, as the largest sector of the economy by volume and workforce, is a significant contributor to environmental degradation. Sustainable solutions mitigate environmental degradation and protect future generations.…

Grades 4 and 8 students had shown slow but steady improvement in scores on the National Assessment of Educational Progress (NAEP) mathematics assessment from 1990 until 2013, but performance since then has been lower despite the introduction of the Common Core State Standards for Mathematics (CCSSM) in the early 2010s. This study examined student…

Geometry education is an important aspect of STEM education and career development, but it is often overlooked in K-12 education in the United States. Although there is some research on teaching geometry to students with learning difficulties at the elementary level, there is a lack of research on teaching advanced geometry skills at high school…

The purpose of this action research study was to investigate by using a PBL design if giving student more ownership in classroom cellphone policies has positive outcomes. This study looked at not only the behavioral aspect of classroom cellphone usage, but also the impacts of using a PBL design on student engagement, ownership, and knowledge…

This study investigated perspectives on extracurriculars by immigrant, non-immigrant Latinx, and non-immigrant Black parents of high school students, as well as potential barriers, if any, to their children's ability to participate in extracurriculars. Drawing upon previous research that demonstrates the positive impact of extracurricular…

Students lacking automaticity of multiplication facts puts them at a disadvantage when learning fifth grade mathematics standards. If students need to use a multiplication chart, or use tally marks, or repeated addition to solve multiplication problems, they struggle to move forward with standards, which involve exponents, fractions, area, and…

There is a major gap in educational best-practices regarding how to scholastically foster diagnostic accuracy among Nurse Practitioner (NP) students. This research establishes foundational information that will lead to evidenced-based educational interventions and curricular changes leveraging the technique of self-explanation in order to increase…

Twenty-five first-year preservice teachers attending a university in the Midwest of the United States of America participated in a whole-class-setting study aimed at investigating their knowledge of how they made sense of fraction concepts and operations, and how the development of this knowledge was facilitated during a mathematics education…

Analogy is a powerful learning mechanism for children to learn novel, abstract concepts from only limited input, yet also requires cognitive supports. My dissertation sought to propose and examine number lines as a mathematical schema of the number system to facilitate both the development of rational number understanding and analogical reasoning.…

The prominence of virtual reality (VR) in the educational field has grown in recent years due to increased availability and lower costs. I conducted a global study regarding how pioneering K-12 teachers use VR to engage students in learning activities. The purpose of this qualitative case study was to identify how and why teachers used VR for…

Researchers and instructors have only recently embraced the role of errors as vehicles for learning in the algebra classroom. Studying a mixture of correct and incorrect worked examples has been shown to be beneficial relative to correct worked examples alone. This study examines the effectiveness of having students generate, or anticipate, errors…

Many students are passively engaged in mathematics content across the United States because they are in classrooms that use traditional instruction methods (i.e. lecture and guided practice). Calculus is a struggle for students because of the critical thinking, conceptual understanding, and problem solving required. Active learning has been shown…
