Novel forms of technology, like shared Augmented Reality (AR) holograms, can spur the discovery of new hypotheses about cognition and how it is embodied and distributed. These holograms have affordances for exploration, collaboration, and learning that have never been seen before. In the present study, we examine the multimodal ways that high…

Along with a global mobility of NNESTs around the world (Canagarajah, 1999), there has been an expanding population of NNEST trainees in the U.S. higher education institutions (Park, 2012). This brought an assumption that there will be an increasing number of international college composition teachers in the U.S. college contexts (Ruecker et al.,…

The purpose of this qualitative phenomenological research study was to investigate the factors that influence mathematical instruction of upper elementary teachers in school districts within Southern California. More specifically, this research study examined teaching strategies of upper elementary teachers' experiences and perceptions regarding…

At-risk students are at risk of falling behind in contributing to tomorrow's 21st-century technological workforce unless educators address deficits early on. Scholars have indicated school librarians can raise at-risk students' self-efficacy levels and address inequity through access to technology and instruction. Nonetheless, there are…

Within teacher education, work on mathematics teaching often occurs separately from work on issues of race and racism. Typically, mathematics content and methods courses tackle subject matter-specific concepts and teaching practices, while the history and current dynamics of racial inequity in education, if addressed at all, tend to be the domain…

This quantitative, ex post facto study is to examine what differences exist, if any, in ACT Aspire math scores based on gender, instructional method, and the interaction between gender and instructional method among ninth grade students taking Algebra 1 in a school district located in Northeast Arkansas. Using a two-way ANOVA, the first main…

This study was conducted to examine the effectiveness of peer-review in college English as Second Language writing classes to improve ESL students' writing scores. It also investigated a statistically significant difference in college ESL students' writing scores between those who use the self-check list and peer review worksheet and those who…

Science museums conduct presentations for their audiences to attract and educate visitors, yet research on presentations has primarily concentrated on whether individual presentations were effective. This mixed-methods, quasi-experimental study looks at how the presenter's mental and physical engagements within a presentation affects audience…

This dissertation consists of three essays that use and develop econometric methods to causally investigate topics in education and development economics. In the first chapter, I develop an econometric framework to correctly and efficiently draw inference in models where estimated value-added (VA) is an explanatory variable (and models where it…

Computers infiltrate almost every aspect of our lives, including our homes and cars. For work, education, or personal fulfillment, computing has increased dramatically. The need for an educated workforce is expanding as technology devices become smaller, faster, and more powerful. We can teach students how to use math, logic, and computational…

Differential item functioning (DIF) analysis refers to procedures that evaluate whether an item's characteristic differs for different groups of persons after controlling for overall differences in performance. DIF is routinely evaluated as a screening step to ensure items behavior the same across groups. Currently, the majority DIF studies focus…

Most school districts across the country continue to research how to help their students become better prepared to enter the workforce and higher education. As a result, the extent to which dynamic teaching techniques affect the success of classroom-taught material currently is not known. Much of the current literature reveals studies on teaching…

This qualitative study explored the perspectives of nine educators on how they define social justice and how they imagine transformational teaching and learning by integrating social justice in their teaching practices. The research sought to answer the following questions (a) How do teachers define social justice? (b) What is a teacher's role in…

Due to COVID-19, all classes in schools have been converted to distance learning using online platforms. However, various problems were raised when converting face-to-face classes to online distance learning. In particular, the difficulties were more pronounced for practical design courses because they include practical experience. In this…

Integrated STEAM education (science, technology, engineering, art, and mathematics) has been shown to effectively foster global competencies as well as school and societal engagement for 21st century learners of diverse backgrounds. However, facilitating quality STEAM teaching and learning can be challenging for teachers, particularly in the area…
