Item response theory (IRT) is currently the dominant methodological paradigm in educational and psychological measurement. IRT models are based on assumptions about the relationship between latent traits and observed responses, so the accuracy of the methodology depends heavily on the reasonableness of these assumptions. This dissertation consists…

In a book published in 2000, entitled "An Elusive Science: The Troubling History of Education Research," Ellen C. Lagemann traced educational research (ER) in the U.S. from its pre-history--the training of common school teachers in summer schools, high schools, normal schools, female institutes, and later colleges and universities.…

School-aged Black boys are mathematically gifted; however, they are often underserved vis-à-vis their mathematics education. In this article, we provide guidance for multiple stakeholders to support and elevate high-quality mathematics learning opportunities for Black male youth. In doing so, we begin by engaging W. E. B. Du Bois' storytelling. We…

There has been a surge in the number of Hispanic-serving institutions (HSIs), which are degree-granting, nonprofit, postsecondary institutions that enroll at least 25% Hispanic/Latinx/e undergraduate students. Although HSI scholarship has increased dramatically since around 2010, there is still a gap in knowledge about individuals who fall within…

This article ponders the question: "How might EdD research methods courses be reimagined to position Black Feminist Theory as a comparable theoretical framework to guide epistemological stance development and scholar-practitioner inquiry?" By introducing Black Feminist Theory as a viable theoretical framework, this article posits its…

The metaverse entails modes of interactivity that hold enormous potential for education in various contexts and domains. The metaverse represents a convergence of technologies, such as immersive virtual reality (VR) and augmented reality, that allow for multimodal engagements with digital objects, virtual environments, and people. In this article,…

An operational multistage adaptive test (MST) requires the development of a large item bank and the effort to continuously replenish the item bank due to concerns about test security and validity over the long term. New items should be pretested and linked to the item bank before being used operationally. The linking item volume fluctuations in…

In chemistry, a eutectic mixture refers to a mixture of two or more components at which the lowest possible freezing point is observed. This phenomenon is covered in a wide range of curricula such as physics, chemistry, chemical engineering, and pharmacy to various depths. Despite the significance of this phenomenon in pharmaceutical compounding…

A tree model for diagnostic educational testing is described along with Monte Carlo simulations designed to evaluate measurement accuracy based on the model. The model is implemented in an assessment of inferential reading comprehension, the Multiple-Choice Online Causal Comprehension Assessment (MOCCA), through a sequential, multidimensional,…

In this theoretical paper, I use an empirically based example to illustrate particular design features of the Learning Through Activity (LTA) design framework and examine the impact of particular design principles. The LTA design framework is based on our elaboration of Piaget's construct of reflective abstraction. The example discussed here,…

This dissertation seeks to answer the following research question: what are the qualitatively different ways that students conceive of an antiracist professional identity for themselves after taking an undergraduate honors course with racism and antiracism as its central themes? To answer this research question, I employ critical race…

Little is known about how middle leaders address concerns with teaching performance. This study used a problem-based methodology and critical incident interviewing to elicit eight middle leaders' theories-in-use for 14 cases of concern. Our systematic analysis examined the beliefs constraining their actions, their actions as well as the resulting…

[This paper is part of the Focused Collection on Qualitative Methods in PER: A Critical Examination.] Qualitative research methods have provided key insights in physics education research (PER) by drawing on non-numerical data such as text or video data. While different methods towards qualitative research exist, they share two essential steps:…

In this process-article, I have considered what complexities might "affect" research of prison education when using Posthuman, Post Qualitative, Feminist (New) Materialism thinking. Through an imagined conversation with these 3 concepts as abstract 'beings', I have answered provocative questions about my research methods, apparatus, and…

Research in psychology and education tend to use large-N group designs that necessitate reporting of mean measures analyzed mostly with null hypothesis statistical testing (NHST), but sometimes with Bayesian, or the estimation approaches in inferential statistics. These approaches all render the average person or student as the the putative…
