Illiteracy impacts the society of the United States socially, economically, physically and mentally. The inability to read has been linked to grim outcomes such as poverty, criminal activity, and poor health. By 2020, the term science of reading had gained traction in the educational realm rather than being isolated knowledge in the cognitive…

Scientific disciplines including mathematics, physics, and chemistry tend to adopt online resources, including websites and web applications, to demonstrate physical experiments and simulate scientific phenomena that are hard to observe and investigate in real world. The present study examined the existing collections of the websites and web…

STEM is a well-known acronym describing the intersections of science, technology, engineering, and math. Emerging from this paradigm is a relatively new interdisciplinary model entitled STEAM. STEAM endeavors to intersperse "the arts" into the sciences with the expectation of increasing student engagement and skills within the sciences.…

Written expression is used throughout the education system and is significant to student success, However, many students express difficulty in this area. The problem is what instructional methods are used to address written expression difficulty within a virtual elementary school environment. Instructional methods used to address this problem are…

While the body of evidence supporting the use of simulation-based learning in the education of health professionals is growing, "how" or "why" simulation-based learning works is not yet understood. There is a clear need for evidence, grounded in contemporary educational theory, to clarify the features of simulation…

My dissertation is situated in the field of computer science education research, specifically, the learning and teaching of programming. This is a critical area to be studied, since, primarily, learning to program is difficult, but also, the need for programming knowledge and skills is growing, now more than ever. This research is particularly…

The cost of college course materials has increased dramatically in recent years. Traditional publishers advocate the use of lower-cost digital and custom editions, but both options have limitations in their ability to save students money (Senack & Donoghue, 2016). Open-educational resources (OER) are openly-licensed materials that may be used…

The study of conceptual change in science education, specifically in the realm of physics, is not new, however, there is still much that is not well understood. Continuing with the trend of including characteristics of the learner in models of conceptual change, this study seeks to explore the role confidence plays in helping or hindering…

Although the motivational factors that underlie the process of mathematics teacher change have been under study for more than thirty years, the role of one of the factors in this process, a teacher's implicit theory regarding mathematical ability, has not been well examined. The implicit theories model posits that an individual's implicit…

This thesis explores two case studies into the use of short answers and self-explanation to improve student learning in physics. The first set of experiments focuses on the role of short answer questions in the context of computer-based instruction. Through a series of six experiments, we compare and evaluate the performance of computer-assessed…

Telehealth can be effective for those who use it; however, very few educational programs prepare their students to utilize telehealth. The goal of this project was to integrate telehealth into the graduate nursing curriculum. This was done by providing a 1-hour classroom educational demonstration and lecture on telehealth along with 4-hour…

Intelligent Tutoring Systems (ITS) have a significant educational impact on student's learning. However, researchers report time intensive interaction is needed between ITS developers and domain-experts to gather and represent domain knowledge. The challenge is augmented when the target domain is ill-defined. The primary problem resides in…

Students often struggle with learning complex chemistry concepts. In today's society with the advances in multimedia technology, educators have a variety of tools available to help students learn these concepts. These tools include demonstrations, videos in the popular media, and animations; referred to collectively as multimethods. With the…

Concepts of Mathematics (21-127 at CMU) is a course designed to introduce students to the world of abstract mathematics, guiding them from more calculation-based math (that one learns in high school) to higher mathematics, which focuses more on abstract thinking, problem solving, and writing "proofs." This transition tends to be a shock:…

There were two purposes of this mixed methods study. The first purpose was to measure the extent of training impact that resulted from management training within a nonprofit environment. To determine potential influences on the extent of training impact, this study included hypotheses that measured specifically whether there was a relationship…
