The purpose of this study was to evaluate high school students' performance in analyzing complex arguments with the support of an off-the-shelf argument mapping software, Rationale™, which provides diagramming tools with guided prompts. This study attempts to: (1) evaluate the quality of student's argument maps in terms of structural…

This study explores using transfer learning in machine learning for natural language processing (NLP) to create generic automated essay scoring (AES) models, providing instant online scoring for statewide writing assessments in K-12 education. The goal is to develop an instant online scorer that is generalizable to any prompt, addressing the…

The potential of speech technology to improve educational outcomes has been a topic of great interest in recent years. For example, automatic speech recognition (ASR) systems could be employed to provide kindergarten-aged children with real-time feedback on their literacy and pronunciation as they practice reading aloud. Within these systems,…

This study examined the effectiveness of the iPad app Mathspace on high school students' algebra computation and skill maintenance. The participants in this study were four ninth grade students enrolled in beginning algebra at a large, urban high school. All four students were struggling to obtain grade-level algebra skills and were reported by…

This dissertation sheds light on how learners of German, NSs of German, and Americans unfamiliar with German reach decisions about the nature of speech acts that they witness NSs of German perform in three authentic video clips. It also aims to gain a better understanding of what sources members of the three groups bring to bear when they attempt…

Computer-mediated collaborative writing has drawn attention from second language researchers and instructors for a few decades, and due to recent developments in Web 2.0 technologies, the possibilities of wikis for collaborative writing have increased enormously. However, few studies have explored the nature of wiki collaboration and interaction,…

The North Carolina Occupational Course of Study (NCOCS) program is an alternative diploma track with a vocational focus toward post school employment to assist students who would not otherwise graduate with a standard course of study. The purpose of this qualitative single case study was to explore the local causes of low post-school employment…

Speaking assessments for second language learners have traditionally been expensive to administer because of the cost of rating the speech samples. To reduce the cost, many researchers are investigating the potential of using automatic speech recognition (ASR) as a means to score examinee responses to open-ended prompts. This study examined the…

A single subject study with multiple baselines across participants was used to explore the effect of giving access to picture-to-text software for writing to young students, with moderate autism, and documented difficulties with written language. For this intervention study, three participants, who had strengths in visual processing and who were…

Wayfinding is a kind of spatial riddle that people encounter almost daily. Although it has been well documented that wayfinding elements--namely, environmental cues, people and time--significantly influence wayfinding, there has been little work done to examine the effectiveness of those influences. In particular, the notion of wayfindingly…

As the number of publications in the biomedical field continues its exponential increase, techniques for automatically summarizing information from this body of literature have become more diverse. In addition, the targets of summarization have become more subtle; initial work focused on extracting the factual assertions from full-text papers,…

The goal of this study was to design an intervention that would help people stay in the continued response phase of the Behavior Change Process and help prevent weight relapse. Using the Behavior Change Process and regulatory focus theory, an intervention was developed that leveraged short message service (SMS) to deliver messages to people who…

The three objectives of this dissertation were to develop a question type model for predicting linguistic features of responses to interview questions, create a tool for linguistic analysis of documents, and use lexical bundle analysis to identify linguistic differences between fraudulent and non-fraudulent financial reports. First, The Moffitt…
