The education of students on existing and emerging technologies in higher education environments requires access to complex software. The rise of the Bring Your Own Device (BYOD) phenomenon in many postsecondary educational institutions, along with the increasing complexity of technological coursework, creates challenges for students needing…

Learning to program has long been known to be a difficult task, requiring a student to develop both fluency in the syntax and grammar of a formal programming language and learn the problem-solving approaches and techniques of computational thinking. The successful teaching strategies of the past have involved maintaining small teacher-student…

The field of computer science education currently lacks consistency in access, equity, and inclusion for students in historically marginalized groups, particularly students with disabilities. At the same time, research demonstrates a need for high-quality teacher professional development to support the inclusion of students with disabilities in…

With the large demand for technology workers all around the world, more people are learning programming. Studies show that human tutoring is the most effective way to learn for novice programmers. However, problems such as the inaccessibility to physical classes, prohibitive costs, and the lack of educators may limit students' opportunities to…

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…

Learning the syntax, semantics, and concepts behind software engineering can be a challenging task for many individuals. This paper examines the Alice 3 software, a three-dimensional visual environment for teaching programming concepts, to determine if it is an effective tool for improving student achievement, raising self-efficacy, and engaging…

This thesis describes a generative model for representing disfluent phenomena in human speech. This model makes use of observed syntactic structure present in disfluent speech, and uses a right-corner transform on syntax trees to model this structure in a very natural way. Specifically, the phenomenon of speech repair is modeled by explicitly…

Since the 1980s, personal computer ownership has become ubiquitous, and people are increasingly using household technologies for a wide variety of purposes. Extensive research has resulted in useful models to explain workplace technology acceptance and household technology adoption. Studies have also found that the determinants underlying…

In spite of the goodwill and best efforts of software engineers and usability professionals, systems continue to be built and released with glaring usability flaws that are costly and difficult to fix after the system has been built. Although user interface (UI) designers, be they usability or design experts, communicate usability requirements to…

With the increasing wealth of information on the Web, information integration is ubiquitous as the same real-world entity may appear in a variety of forms extracted from different sources. This dissertation proposes supervised and unsupervised algorithms that are naturally integrated in a scalable framework to solve the entity resolution problem,…

As India aspires to become the information and communication technology (ICT) leader in the world, the education of its children is a primary concern. While India's policymakers expect ICT to usher in promising education changes, there is a limited understanding of how computers are used and negotiated in India's schools. This dissertation is an…

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…

Girls and women continue to be underrepresented in high school Advanced Placement computer science courses, undergraduate and graduate computer science programs at colleges and universities, and engineering programs and related careers. This is not to suggest that public schools train students to fulfill specific job needs, yet it is evident that…

Among educational researchers and practitioners, there is a growing interest in employing computer games for pedagogical purposes. The present research integrated a technology education class and a science class where 5th graders learned about environmental issues by designing games that involved environmental concepts. The purposes of this study…
