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…

Many children are attending after-school programs for various reasons, such as academic support, recreational play, and social interaction. Accompanied by high parental demands for affordable child-care, after-school program participation has increased significantly. The issue of quality care becomes important as the number of children enrolled in…

The purpose of this study was to assess and describe the status of program evaluation within the National Science Foundation's (NSF) Research Experiences for Undergraduates (REU) sites. The National Science Foundation's REU program supports thousands of undergraduates annually in hands-on, immersive research experiences under the mentorship of…

This dissertation explores conceptual and methodological issues related to measuring implementation in quantitative educational research. Implementation, defined as the enactment of interventions in educational contexts, plays a pivotal role in understanding how programs operate and affect student outcomes. Despite its importance, there is…

In education research test scores are a common object of analysis. Across studies test scores can be an important outcome, a highly predictive covariate, or a means of assigning treatment. However, test scores are a measure of an underlying proficiency we can't observe directly and so contain error. This measurement error has implications for how…

The purpose of this replicated systematic review (SR) and meta-analysis was to examine the literature base of single-case research design studies using video analysis to determine the intervention's effectiveness on teacher outcomes. Using a primary search and an ancestral, citation, and first author searches, this study evaluated participant,…

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…

This study showed extent of rigor at North Louisiana school sites using a Likert Scale questionnaire and observation rubric, derived from the Rigor/Relevance Framework and COMPASS rubric, respectively. Cognitive thinking is highly regarded by educators and employers in a global economy as students use it to infer, connect, and apply knowledge to…

The current shift in U.S. educational reform toward standards and guiding frameworks that are more inclusive of twenty-first-century competencies has created a need for research regarding the assessment of these skills. Also, needing further exploration is an understanding of how these new learner-centered assessments may impact students.…

In an effort to understand how school boards in America's K-12 school system function, a research collaboration was undertaken among four agencies: the National School Boards Association, the Thomas B. Fordham Institute, the Iowa Association of School Boards, and the Wallace Foundation. These groups joined effort to conduct research on school…

This study looked at the effect of a number of factors such as the choice of analytical method, the handling method for missing data, sample size, and proportion of missing data, in order to evaluate the effect of missing data treatment on accuracy of estimation. In order to accomplish this a methodological approach involving simulated data was…

Fidelity of implementation (FOI) is the extent to which delivery of an intervention adheres to the original intent of the program designer. FOI in educational studies is hindered by the lack of a universally agreed upon definition or set of criteria for measurement. With the increasing need for justification of reliability and validity of…

This study arose from an interest in the possible presence of mathematics disabilities among students enrolled in the developmental math program at a large university in the Mid-Atlantic region. Research in mathematics learning disabilities (MLD) has included a focus on the construct of working memory and number sense. A component of number sense…

This dissertation comprises three papers that propose, discuss, and illustrate models to make improved inferences about research questions regarding student achievement in education. Addressing the types of questions common in educational research today requires three different "extensions" to traditional educational assessment: (1)…

The purpose of this study was to learn about the experiences of teachers as they transition from traditional grading practices to standards-based reporting (SBR). In order to achieve this overall objective, the following research questions framed this qualitative study: (1) What understandings related to practices do middle school teachers have as…
