Calculation of the correct dosages is a key factor for safe patient medication administration. For decades nurse educators have aimed to improve the knowledge and skills of the pre-licensure nursing students for medication administration. In a midwestern prelicensure nursing school, a program was implemented using a curriculum wide approach for…

Mathematics education is constantly changing due to the growing use of computers worldwide, and these global changes greatly affect mathematics education. In a computerized and changing society, it is paramount schools prepare students to acquire both procedural knowledge and conceptual knowledge in mathematics. In the state of Georgia, fourth…

The purpose of this study is to investigate the effect of use of graphing calculators on student achievement in Common Core Algebra I. The following are the research questions of the proposed study. To what extent does use of graphing calculators in the math classroom affect student achievement? How might the use of graphing calculators in the…

In basic regression discontinuity (RD) designs, causal inference is limited to the local area near a single cutoff. To strengthen the generality of the RD treatment estimate, a design with multiple cutoffs along the assignment variable continuum can be applied. The availability of multiple cutoffs allows estimation of a pooled average treatment…

Recent policies and initiatives emphasized the importance of helping all students acquire Computer Science (CS) knowledge and develop Computational Thinking (CT). This study investigated the impact of a school-university partnership model on school students' CT development in the context of an after-school program. This study also examined the…

The purpose of the study was to explore the cognitive profiles associated with inadequate responsiveness to fractions intervention on 3 fractions outcomes (calculations, ordering, and word problems). At the start of 3rd grade, 2 cohorts of students (N = 124) identified at the start of intervention as at-risk for mathematics difficulties were…

Crowdsourcing is an emerging research area that has experienced rapid growth in the past few years. Although crowdsourcing has demonstrated its potential in numerous domains, several key challenges continue to hinder its application. One of the major challenges is quality control. How can crowdsourcing requesters effectively control the quality…

Graphs are widely used to model structures and relationships of objects in various scientific and commercial fields. Chemical molecules, proteins, malware system-call dependencies and three-dimensional mechanical parts are all modeled as graphs. In this dissertation, we propose to mine and index those graph data to enable fast and scalable search.…

In many evolving systems, inputs can be derived from both human observations and physical sensors. Additionally, many computation and analysis tasks can be performed by either human beings or artificial intelligence (AI) applications. For example, weather prediction, emergency event response, assistive technology for various human sensory and…

There is a broad interest in narrowing achievement gaps among all groups of students and improving education by scientifically sound methods. On October 25, 2006, the United States Department of Education published new regulations allowing single-sex education in public schools whenever schools think it will improve student achievement. Thus far,…

Success in early literacy activities is associated with improved educational outcomes, including reduced dropout risk, in-grade retention, and special education referrals. When considering programs that will work for a particular school and context; cost-effectiveness analysis may provide useful information for decision makers. The study…

According to industry representatives, computer science education needs to emphasize the processes involved in solving computing problems rather than their solutions. Most of the current assessment tools used by universities and computer science departments analyze student answers to problems rather than investigating the processes involved in…

The purpose of the study was to demonstrate improvements in celerations, performance changes, and fluency of digits written correctly using repeated drill and practice procedures with Precision Teaching measurement approaches during one-minute timings among middle school students who also exhibit identified emotional and/or behavioral disabilities…

Scale linking is the process of developing the connection between scales of two or more sets of parameter estimates obtained from separate test calibrations. It is the prerequisite for many applications of IRT, such as test equating and differential item functioning analysis. Unidimensional scale linking methods have been studied and applied…
