Virtual reality can be used to enhance education, especially in the remote context. Cross-reality interfaces can be useful for users who wish to access shared virtual spaces from different devices. Emotion recognition can then be used to supplement the lost non-verbal cues and allow teachers to address students in need. We introduce several types…

Interacting with objects in virtual reality can be an exciting experience. Haptic feedback allows virtual environments to appear more immersive. Does this increased immersion bear the potential to enhance learning if used properly in educational VR environments? This dissertation pursued two goals. First, to investigate the relationship between…

To realize more equitable technology futures, it is not enough to simply adapt technology to be more inclusive "after" it is created. We will also need to equip technology creators with the skills they need to critically reflect upon bias and exclusion "during" the technology design process. The question of how to best to…

The ability to efficiently optimize or re-optimize an algorithm for high performance on a particular processor architecture is crucial in a wide spectrum of engineering and scientific applications. To help bridge the gap between fully automated optimization, which does not reliably produce optimal code, and fully manual optimization, which is…

Undergraduate Research (UR) is a high-impact practice that results in positive outcomes for participants, such as improved academic skills and intellectual development as well as higher graduation rates and graduate school attendance. This research project compares the UR participation patterns of students with learning disabilities (LD) and their…

Computer science instructors typically have many responsibilities, such as creating material, delivering lectures, clarifying student questions, and grading student deliverables, while the demand for computer science education has been increasing. Handling all of these responsibilities is challenging in itself. However, it is made worse when…

Abstract databases are essential for literature reviews, and in turn for the scientific process. Research into user interface designs and their impact on scientific article discovery is limited. The following study details the process of building a new abstract database and explores several user interface design elements that should be tested in…

In this thesis, we hypothesize that data visualization users are subject to systematic errors, or cognitive biases, in decision-making under uncertainty. Based on research from psychology, behavioral economics, and cognitive science, we design five experiments to measure the role of anchoring bias, confirmation bias, belief bias, and myopic loss…

The shift to online learning management systems such as Canvas seemed to assume students would become more independent and self-regulated, yet little research has been conducted in this area, especially with school-age students. This study examined the ways middle school students engaged with an online learning management system (LMS) and their…

The COVID-19 crisis upended the typical college experience as educational institutions had to close campuses and send students home mid-semester in the spring of 2020. The COVID-19 pandemic left educators around the world with limited choices on how to move forward with high quality education for all. This abrupt closing of higher education…

In the age of big data, interactive data visualizations are becoming increasingly prevalent. The ability to focus on subsets of data is essential for exploring large temporal, geospatial, topical, and network datasets. In order to categorize all parts of data visualizations, various attempts have been made to build frameworks for how to interpret,…

Current online video interaction is typically designed with a focus on straightforward distribution and passive consumption of individual videos. This "click play, sit back and watch" context is typical of videos for entertainment. However, there are many task scenarios that require active engagement and analysis of video content as a…

In just a short time, mobile devices have revolutionized the way we access information and interact with each other. With an ever expanding list of sensors and features, these devices are also capable of reshaping our experiences with physical systems. Prior efforts to explore this potential of mobile devices have often considered traditional user…

Here we demonstrate how more highly interoperable computable knowledge enables systems to generate large quantities of evidence-based advice for health. We first provide a thorough analysis of advice. Then, because advice derives from knowledge, we turn our focus to computable, i.e., machine-interpretable, forms for knowledge. We consider how…

Information Retrieval (IR) is one of the most evolving research fields and has drawn extensive attention in recent years. Because of its empirical nature, the advance of the IR field is closely related to the development of various toolkits. While the traditional IR toolkit mainly provides a platform to evaluate the effectiveness of retrieval…
