Monte Carlo methods are an accepted methodology in regards to generation critical values for a Maximum test. The same methods are also applicable to the evaluation of the robustness of the new created test. A table of critical values was created, and the robustness of the new maximum test was evaluated for five different distributions. Robustness…

Educational research outcomes frequently rely on an assumption that measurement metrics have interval-level properties. While most investigators know enough to be suspicious of interval-level claims, and in some cases even question their findings given such doubts, there is a lack of understanding regarding the measurement conditions that create…

The purpose of this research was to create a Culture of Assessment Instrument (Appendix F) that will allow education program provider (EPP) assessment leaders to measure the assessment culture within their program. General Systems Theory was the theoretical framework as the foundation of this research. Using a modified Delphi panel of assessment…

In an increasingly data-driven society, making decisions with data is a requirement not only for research scientists but also for navigating life more generally (Kjelvik & Schultheis, 2019). An informed citizenry must be prepared to discover patterns, predict outcomes, make decisions with data, and evaluate data-based claims for legitimacy and…

Recent research has shown the use of standardized placement testing has caused more students to place incorrectly into developmental education due to the narrow and rigid cut scores. Placing unnecessarily into developmental education can be costly for both the student and the institution and cause negative emotional effects that may lead students…

Statistics & data science are growing, rapidly evolving, and increasingly important for an informed citizenry in a data-saturated world. In this dissertation, I address two central questions: (1) who is taking statistics? and (2) what are statistics courses teaching? I estimate that 920,000 US students take statistics in high school each year,…

This teacher-research study explored how opportunities for multimodal project learning provided time in the classroom for ongoing conversations and inquiries that promoted student agency and growth, cultivated content and literacy learning, and inherently provided authentic assessment opportunities. This study documented the multimodal curriculum…

This three-paper dissertation systematically investigates the methodology issues related to using observational systems to observe, analyze, and interpret teachers' reformed teaching practices within the K-12 classroom context. Each paper contributes a distinct perspective to evaluate instructional practices accurately, consistently, and…

Psycholinguistics is the research of language in the mind: The architecture of storing the different components of language in our memory, and the ways we access that knowledge when processing and producing language. Psycholinguists usually conduct quantitative experimental research in which certain standards of experimental design, data…

This multiple manuscript dissertation offers a cohesive set of research studies curated to address three topics related to how high-quality instructional practice (HQIP) is defined, measured and ultimately connected to student engagement and achievement. Grounded in Benson's (1998) framework of construct validation, this line of inquiry outlines:…

Operationalism, representationalism, and pragmatism are three major philosophies of measurement in psychology and education. These philosophies play important roles in designing and conducting measurements, as well as interpreting results. When measurement results are available, validity evidence plays important roles in supporting the…

Over the last several decades, significant pressures resulting from financial challenges, declining undergraduate enrollments, changing demographics and now the COVID-19 pandemic, have caused college and university leaders to consider interinstitutional merger for both economic and strategic purposes. However, both knowledge and methodological…

In randomized control trials (RCT), the recent focus has shifted to how an intervention yields positive results on its intended outcome. This aligns with the recent push of implementation science in healthcare (Bauer et al., 2015) but goes beyond this. RCTs have moved to evaluating the theoretical framing of the intervention as well as differing…

Large-scale assessments, a prominent part of education in the United States, are the accountability measures used to determine policies, programs, and the allocation of resources. The U.S. school population continues to have an increasing number of culturally and linguistically diverse (CLD) students, indicating the need to reevaluate the…

This study aims to explore the validity of measuring joint attention through gaze coordination in computer-supported collaborative learning (CSCL) research. Gaze coordination, aligning visual attention in social contexts, aids comprehension and communication. Many CSCL researchers use gaze coordination to gauge joint attention quantitatively.…
