This study introduces a longitudinal diagnostic classification model, called the LTA+HDCM, which is a fusion of latent transition analysis (LTA; Collins & Flaherty, 2002; Collins & Wugalter, 1992) and the hierarchical diagnostic classification model (HDCM; Templin & Bradshaw, 2014). The primary goals in this study are (1) to evaluate…

The purpose of this dissertation was to develop and use a platform that facilitates Massive Open Online Course (MOOC) replication research. Replication and the verification of previously published findings is an essential step in the scientific process. Unfortunately, a replication crisis has long plagued scientific research, affecting even the…

Randomized experiments involving education interventions are typically implemented as cluster randomized trials, with schools serving as clusters. To design such a study, it is critical to understand the degree to which learning outcomes vary between versus within clusters (schools), specifically the intraclass correlation coefficient. It is also…

We explore how experienced informal educators worked towards equitable and consequential opportunities for learning in informal STEM settings through pedagogical practice. Drawing from a justice-centered social practice stance we argue that pedagogical practice that promotes social transformation towards more just futures must confront and respond…

Drawing upon ongoing research exploring lived experiences of sensory overload, meltdown, and shutdown in autism as a framework, this article reflects on the challenges and benefits of employing participatory methods in doctoral research. In particular, the process of establishing and working with a Research Advisory Group to co-create a…

In science in general and in the context of single-case experimental designs, replication of the effects of the intervention within and/or across participants or experiments is crucial for establishing causality and for assessing the generality of the intervention effect. Specific developments and proposals for assessing whether an effect has been…

As wider social and societal changes have led to moves towards equality as a response to a better understanding of inequalities, ethical considerations in research are now more consciously focussed on power dynamics. As a consequence, participatory research methods have gained traction. Simultaneously, artistic and creative methods are used within…

Special educators serve a diverse population of students with unique strengths and needs, and adaptive interventions that account for individual differences before and during the intervention are an important tool to moving the field toward more individualized practices. The purpose of this article is to detail the conceptualization and…

This study presented the theoretical model applied to the research design with descriptions of the overall sample, survey sample, research location, etc. The main contents of the design and research organization and the results obtained in theory have been applied in practice. The results have fully met the scientific and technical requirements of…

Practice-based research is perceived as significantly important to enhance the quality of social studies education in the literature. In particular, graduate dissertations have great potential for contributing to the literature, and using research methods, and designs that improve practice is valuable in graduate-level research. This study focuses…

The purpose of this paper is to introduce the Five-Level Qualitative Data Analysis (5LQDA) method for ATLAS.ti as a way to intentionally design methodological approaches applicable to the field of evaluation. To demonstrate my analytical process using ATLAS.ti, I use examples from an existing evaluation of a STEM Peer Learning Assistant program.…

By illuminating why and how interventions work in real world settings, Implementation Research (IR) is a powerful tool for increasing the likelihood that evidence-based interventions, programmes and policies are successfully implemented. The insights that IR generates help bridge the 'know-do gap'--the gap between what we know works and what…

The need for quality research outputs is clearly undeniable in any context that values quality knowledge production. This study examined consistency among epistemologies, theoretical perspectives, methodologies, and methods in students' dissertations. It also aimed to assess the extent to which the dissertations employ a variety of research…

Purpose: Systematic reviews of literature are routinely conducted to identify practices that are effective in addressing educational and clinical problems. One complication, however, is how best to combine data from both group experimental design (GED) studies and single-case experimental design (SCED) studies. Percent of Goal Obtained (PoGO) has…

Systems for learning and producing knowledge, such as career and technical education (CTE), often reproduce inequities unless an equity-focused lens is used when designing, implementing, and evaluating programs. This framework presents guidance for conducting CTE research with an intentional focus on equity. Developed by the CTE Research Network's…
