The post-pandemic classroom dealt with not only the mental health struggles of educators and students, but also the technological and virtual learning dependence in a time ridden with misinformation. At this time, it was important to not only consider the purpose and intent of science education as a learning experience, but also pedagogical…

Understanding human behavior and reasoning is essential for developing successful instruction. Discipline-based education researchers have examined how students learn, informing the development of successful instructional strategies. Researchers have also identified barriers to the successful implementation of such strategies. This work utilizes…

This action research study aimed to find ways to adjust my practice by incorporating inquiry-based, science activities and virtual simulations to improve student conceptual understanding of physical and chemical changes. A multi-lesson, curricular intervention combining inquiry-based activities and virtual simulations was developed using…

In this dissertation I will present my work in both the fields of spintronics and physics education research. In the first section, I present a method to account for spin pumping in spin torque ferromagnetic resonance (ST-FMR) measurements. A spin current can be generated via the spin Hall effect (SHE), which is typically transverse to the charge…

Active learning is widely recognized as superior to traditional passive, lecture-based techniques for fostering learning in STEM courses. Interactive, hands-on learning where students interact with their peers and physical systems is an effective type of active learning. As the need for scientists and engineers continues to grow, understanding and…

Achieving an in-depth understanding of unfamiliar science concepts has been found to be difficult when learners can not index science language to relevant sensorimotor experiences. Ongoing research in embodied cognition highlights the importance of relevant sensorimotor experiences in understanding and learning new information. Aiming to foster…

Guided authentic scientific inquiry activities can give students a clear picture of the nature of science and how its fields operate in practice, but such activities are difficult to do well. Too much structure negates the benefit of open-ended activities and student-led investigation, while too little can result in frustration or unproductive…

This practitioner action research study explored features of NGSS-based pedagogies to improve secondary education student engagement, critical thinking, and collaborative problem-solving. It examined ways that constructivist pedagogies might encourage students to understand science by putting their skills and knowledge into practice as young…

This dissertation describes a practitioner's design-based development of a prototype chatbot to guide students in learning biological concepts of genetic mutations and protein synthesis. This chatbot's architecture provides learning activities, feedback, and support throughout a series of short, connected lessons. The chatbot is designed to…

The effect of class size on student learning has numerous policy implications and has been a major subject of conversation and research for decades. Despite this, few studies have been done on class size in the context of university settings or physics courses. This dissertation helps address that gap in the literature by quantitatively analyzing…

The underrepresentation of women in STEM more generally and in physics specifically has been well established (e.g., Hyater-Adams, Fracchiolla, Finkelstein, & Hinko, 2018; Johnson, Ong, Ko, Smith, & Hodari, (2017); Lock & Hazari, 2016), and the field remains challenged by the negative consequences of this underrepresentation. Women's…

The purpose of this qualitative study was to explore the use of 3-D printed models as an instructional tool in a middle school science classroom for students with visual impairments and compare their use to traditional tactile graphics for aiding conceptual understanding of geoscience concepts. Specifically, this study examined if the students'…

Studies have shown an association between argumentative discourse in science class, better understanding of science concepts, and improved academic performance. However, there is lack of research on how argumentation can increase student motivation. This mixed methods concurrent nested study uses Bandura's construct of motivation and concepts of…

The availability and sophistication of visual display images, such as simulations, for use in science classrooms has increased exponentially however, it can be difficult for teachers to use these images to encourage and engage active student thinking. There is a need to describe flexible discussion strategies that use visual media to engage active…

The purpose of this study was to identify the preferred instructional design strategies for the preparation of pre-service teachers who will deliver integrated STEM lessons. The research objectives were threefold and included identifying a preferred definition of integrated STEM education, developing its purpose statement, and creating a list of…
