The town motto, "people of pride and purpose," is evident throughout Panhandle, Texas. In a town of 2,000, one-third of the population is school-age children, and all attend Panhandle elementary (pre-K-5), junior high (6-8), or high school. The Panhandle Panthers have a lot of school pride, which stems in large part from the Panhandle…

Building an early childhood system within the District is similar to efforts taken to complete an intricate puzzle. Imagine having to assemble a 5,000-piece puzzle without access to the box depicting its final image. The puzzle must be constructed without an organized leader by a group of people who speak different languages. Moreover, a…

As state policies promote, and parents demand, high-quality child care, states must better understand both the strengths and needs of its early care and education workforce. In 2016, the Center for the Study of Child Care Employment launched its biennial Early Childhood Workforce Index to describe the early childhood workforce conditions and…

Students must choose when to take the ACT for the first time and if and when to retest. States and districts that administer the ACT test to all students must also choose when to administer the test. A key consideration in making these decisions is the impact on scores. Because the ACT is a curriculum-based test of academic achievement, students…

This qualitative study utilized a Case Study method to explore how district administrators utilized their lived experiences as members of one or more marginalized groups to lead their schools in urban districts. There was a focus on how they self-identified and leveraged their membership in their cultural and racial groups to positively impact…

Over the last three decades, there has been increased attention on the collection and interpretation of "response processing data" to inform claims of learners' knowledge and skills (e.g., see Ercikan et al., 2010; Kobrin & Young, 2003; see also, Leighton, 2004). Response processing data are perhaps most consequential in the…

In 2016, MENTOR and its affiliates led the largest data collection effort in almost 20 years to examine the prevalence and practices of youth mentoring programs across America. The effort had had three major goals: (1) Better understand the structure, services, and challenges of mentoring programs so that MENTOR and its affiliates could provide…

This dissertation focuses on elite efforts to restructure work and education in the Russian data sciences. Russia has long had a strong national program in theoretical mathematics, but has been substantially less successful at applying this expertise to develop modern computational science, infrastructure, and business. As the Russian extraction…

This case study reports my experiences of a PhD project applying the microgenetic approach to study changes in students' conceptual structures as they developed understanding of topics in physics. The microgenetic approach involves sampling (referring to the frequency of application of data collection probes) a phenomenon at a rate which is high…

With the continued adoption of learning analytics in higher education institutions, vast volumes of data are generated and "big data" related issues, including privacy, emerge. Privacy is an ill-defined concept and subject to various interpretations and perspectives, including those of philosophers, lawyers, and information systems…

N signifies the number of data samples in a study. Traditional research values numerous data samples as this reduces the variability created by extremes. Alternatively, arts-based research privileges the outlier, the N of 1. Oftentimes, what is unique and outside the norm is the focus. There are three approaches to the N of 1 in arts-based…

In measurement theory, causal indicators are controversial and little understood. Methodological disagreement concerning causal indicators has centered on the question of whether causal indicators are inherently sensitive to interpretational confounding, which occurs when the empirical meaning of a latent construct departs from the meaning…

Scientists produce vast amounts of data that often are not preserved properly or do not have inventories, placing them at risk. As part of an effort to more fully understand the data-at-risk predicament, researchers who were engaged in the DARI project at UNC's Metadata Research Center surveyed information custodians working in a range of…

The purpose of this paper is to give an example of how to assess the model-data fit of unidimensional IRT models in simulated data. Also, the present research aims to explain the importance of fit and the consequences of misfit by using simulated data sets. Responses of 1000 examinees to a dichotomously scoring 20 item test were simulated with 25…

Nonoverlap is widely used as a statistical summary of data; however, these analyses rarely correct unwanted positive baseline trend. This article presents and validates the graph rotation for overlap and trend (GROT) technique, a hand calculation method for controlling positive baseline trend within an analysis of data nonoverlap. GROT is…
