Data visualization is a powerful strategy for using graphics to represent data for effective communication and analysis. Unfortunately, creating effective data visualizations is a challenge for both novice and expert design users. The task often involves an iterative process of trial and error, which by its nature, is time-consuming. Designers…

Augmented Reality (AR) is a medium that gives people the ability to engage with digital information in ways that deviate from more traditional HCI methods (e.g. WIMP user interfaces (Christensson, 2014)). Previous work has shown that AR has useful implications for collaboration, and with remote work experiences and teleconferencing becoming…

In recent years, modern technologies have enabled the collection of exponentially larger quantities of data in the biomedical domain and elsewhere. In particular, the advent of single-cell genomics has allowed for the collection of datasets containing hundreds of thousands of cells measured in tens of thousands of dimensions. This rapid expansion…

Graph data, especially large graph data, come up in many domains, such as social networks, the map of science, biological data, and even knitting! This presents a problem when we consider visualizing these structures. Layouts must be chosen carefully so that the structure of the graph is visible. Some graphs are large enough and connected enough…

The phenomenological research study explores the lived experience of Black first-generation college students navigating the financial aid process to understand how they experience the process of using financial aid to pay for college through degree attainment. Higher education is aligned with social and occupational mobility. Financial aid has its…

The central focus of my dissertation concerns the issue of representation. The issue of representation is important for science education research for two reasons: (1) the use of external representation in science teaching and learning, particularly in chemistry education, is ubiquitous as microscopic entities are not directly visible, and (2) the…

This research investigates significant moments in college students' drawn life stories in mathematics with the aim of examining implications for STEM engagement and potential reasons for gender-related differences in participation in mathematics intensive STEM fields. My research employs drawn life stories in mathematics specifically focused on…

Individuals with developmental disabilities demonstrate deficits in intellectual and adaptive functioning that can include difficulty describing past events; accurate recall may be improved by learning to engage in precurrent, or problem solving, behavior. Visual imagining is a problem-solving strategy that involves seeing in the absence of the…

We humans are cultural and ecological beings. This is a study about children's drawing as a device for expressing intertwined cultural and ecological relations. Countless studies have examined children's drawing from psychological, anthropological, linguistic, and aesthetic perspectives, while recently posthuman perspectives have put forward…

At the highest level, this dissertation is a case study on how bias can become encoded into the tools used to measure a construct and into the very definition of the construct itself. In this case, the construct is spatial ability. This dissertation focuses on the validity and accuracy of spatial tests and illuminates gender bias that is…

This dissertation is intended to aid school systems in creating leadership education programs for high school and college aged students. A visualization education curriculum is potentially developed by using the research and commentaries of many pedologists, teachers, counselors, athletes, business individuals, and psychologists. Ideas include a…

This study aimed to contribute to the literature by examining the impacts of using GeoGebra on students' perceptions and achievement in learning geometric transformations. This study contributes to mathematics education and learning environments supported by GeoGebra. This study reviewed the literature on social constructivist learning theory and…

Chemistry is considered a difficult subject by most students. Its difficulty lies in Chemistry's complex and abstract nature. This highly abstract nature requires constant interplay and coordination between the macroscopic, particulate, and symbolic representations. Experts can successfully navigate the various representations without overloading…

CAL (Computer Assisted Learning) programs are widespread today in schools and families due to the effectiveness of CAL programs in improving students' learning and task performance. The flourishing of CAL programs in education has brought large amounts of students' learning data including log data, performance data, mouse movement data, eye…
