One way that examinees can gain an unfair advantage on a test is by having prior access to the test questions and their answers, known as preknowledge. Determining which examinees had preknowledge can be a difficult task. Sometimes, the compromised test content that examinees use to get preknowledge has mistakes in the answer key. Examinees who…

Using two paired datasets from the Head Start Program Information Report and Migrant and Seasonal Head Start (MSHS) Study, this study explored disparities in program rates of screening, referral, and identification for early intervention between MSHS and Head Start programs, as well as associations between MSHS teacher ratings of children's…

The goal of biological sciences is to understand the biomolecular mechanics of living organisms. Proteins serve as the foundation for organisms functional analysis and sequence analysis has shown to be invaluable in answering questions about individual organisms. The first step in any sequence analysis is alignment and it is common that even…

This study analyzed the meta-data collected from a honeypot that was run by the Federal Bureau of Investigation for a period of 5 years. This analysis compared the use of existing industry methods and tools, such as Intrusion Detection System alerts, network traffic flow and system log traffic, within the Open Source Security Information Manager…

"For valid disability determination to occur, a diagnostic team needs to be able to determine that a student has received appropriate instruction in the general education classroom" (Johnson, Mellard, Fuchs, & McKnight, 2006, p. 4.2). The purpose of the study was to determine whether a middle school Response to Intervention (RTI)…

That organizations face threats to the security of their computer systems from external hackers is well documented. Intentional or unintentional behaviors by organizational insiders can severely compromise computer security as well. Less is known, however, about the nature of this threat from insiders. The purpose of this study was to bridge this…

There is a persistent gap in the representation of African American students in gifted programs in U.S. PK12 public schools. The students who are invited to gifted programs are overwhelmingly White. African American gifted students are under identified by their teachers in public schools in PK12 in the United States. Unawareness of cultural…

This study strived to determine the effectiveness of the AR phonics program relative to the effectiveness of the scripted phonics program for developing the letter identification, sound verbalization, and blending abilities of kindergarten students considered at-risk based on state assessments. The researcher was interested in pretest and posttest…

Data and the use of data to make educational decisions have attained new-found prominence in K-12 education following the inception of high-stakes testing and subsequent linking of teacher evaluations and teacher-performance pay to students' outcomes on standardized assessments. Although the research literature suggested students' academic…

This dissertation examines two related questions. "How do mixed membership models work?" and "Can mixed membership be used to model how students use multiple strategies to solve problems?". Mixed membership models have been used in thousands of applications from text and image processing to genetic microarray analysis. Yet…

Outlier detection is an important data mining task that is focused on the discovery of objects that deviate significantly when compared with a set of observations that are considered typical. Outlier detection can reveal objects that behave anomalously with respect to other observations, and these objects may highlight current or future problems. …

The aim of this study was to examine the experiences of international undergraduate students who are identified with learning disabilities and enrolled in universities in the United States. There is a dearth of studies investigating the unique needs and challenges of this population. This is the first study to explore the phenomenon of…

This dissertation examined the impact that Proposition 227 had upon the identification and placement of English language learners in Special Education programs in small, necessary Special Education Local Plan Areas (SELPAs) in the state of California. Furthermore, this dissertation studied the practices and strategies used by small, necessary…

This study of taking-on was conducted using classical grounded theory methodology (Glaser, 1978, 1992, 1998, 2001, 2005; Glaser & Strauss, 1967). Classical grounded theory is inductive, empirical, and naturalistic; it does not utilize manipulation or constrained time frames. Classical grounded theory is a systemic research method used to generate…

Students often make errors when trying to solve qualitative or conceptual physics problems, and while many successful instructional interventions have been generated to prevent such errors, the process of deduction that students use when solving physics problems has not been thoroughly studied. In an effort to better understand that reasoning…
