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…

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…

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,…

To access interactive systems, blind and visually impaired users can leverage their auditory senses by using non-speech sounds. The current structure of non-speech sounds, however, is geared toward conveying user interface operations (e.g., opening a file) rather than large theme-based information (e.g., a history passage) and, thus, is ill-suited…

This study examined the process teachers used to change their pedagogy to deliver effective instruction using Web 2.0 tools. A phenomenological approach examined the "lived experiences" of seven secondary teachers through in-depth interviews giving this study an in-depth qualitative analysis of teachers and technology. The widening…

Using touch screens presents a number of usability and accessibility challenges for blind people. Most touch screen-based user interfaces are optimized for visual interaction, and are therefore difficult or impossible to use without vision. This dissertation presents an approach to redesigning gesture-based user interfaces to enable blind people…

This dissertation makes the claim that electronic scholarly editions have the potential to produce more reliable scholarly texts than their print-based antecedents. It consists of an introduction, four chapters, and a brief conclusion. It originated in my work creating the Elwood Viewer, a sophisticated software browser written to display TEI…

This thesis is about a design process for creating "educationally relevant" tools. I submit that the key to creating tools that are educationally relevant is to focus on ensuring a high degree of alignment between the designed tool and the broader educational context into which the tool will be integrated. The thesis presents methods and processes…

This study looks at the relationship between age, technology experience, and design factors in determining young children's comprehension of novel digital interfaces. In Experiment 1, 35 preschoolers played three games that varied in complexity and familiarity. Parental questionnaires were used to assess children's previous technology experience.…

This study examined the effects of manipulating the modality (text-only, voice-only, voice+text) of a tutorial and restriction (restricted vs. unrestricted) of a simulation's interface on retention and transfer of tutorial content. The tutorial prepared novice students to use Packet Tracer, a simulation developed by Cisco that teaches network…
