Introduction: Missing data are bound to occur in education intervention research. Reasons vary but always have the consequence of reducing sample sizes and can, under certain conditions, seriously bias estimated intervention effects. A wide array of methods have been developed for handling missing data (Enders, 2023). Whereas older approaches…

Doctoral education is the primary time in which scholars learn about research methodologies and begin to develop their own research agendas and skills. Yet, to date, few research studies have examined graduate students' perceived value of, and access to, training in multiple research methodologies. The purpose of this study was to explore special…

Mixed methods research (MMR) can serve to bridge fields of study disconnected by differences in content, epistemologies, and methods. Such bridging can benefit fields that are interconnected in practice but generally separated in research, such as educational research with its silos of "general" and "special" education in…

Mixed methods research (MMR) can support enhanced understanding of complex educational issues, like the inclusion and support of individuals with disabilities in community and school settings. In this systematic review, we explored the extent to which MMR has been used in research exclusively focused on disability across special education (SPED),…

The use of multi-sensory data collection tools with children in special and inclusive education is increasing in popularity. Many studies in this area have highlighted the potential for photography, drawings and other visual data collection methods to capture children's perspectives on inclusive practice. However, these tools are likely to be less…

Although quality guidelines for single-case intervention research emphasize the importance of concurrent baselines in multiple-baseline and multiple-probe designs, nonconcurrent variations on these designs persist in the research literature. This study describes a systematic review of special education intervention studies (k = 406) between 1988…

Mixed-methods research (MMR) holds promise for investigating several empirical questions within special education, capitalizing on the strengths of quantitative and qualitative traditions. We present an overview of MMR in special education and quality indicators for conducting and reporting such studies. We look to the future for how MMR may…

Mixed methods research (MMR) has the potential to be a powerful tool to expand the ways early intervention/early childhood special education (EI/ECSE) scholarship understands and informs practice. Integration, or the purposeful combination of quantitative and qualitative research approaches, is central for rigorous MMR. However, it can be…

The field of special education stems from the efforts of parents, adults and children with disabilities, invested policymakers, and other civil rights advocates within legal and policy forums. Yet, over time, as intervention- and scientific-based research within special education were moved to the forefront, the focus on how special education…

Mixed-methods research can uniquely inform special education practice by combining qualitative and quantitative research approaches. However, its distinct features can also make mixed-methods research difficult to understand and apply. In this article, we provide an introduction to mixed-methods research purposes, designs, and quality…

This study aims to descriptively analyze the studies on multiple disabilities in Türkiye between 2008 and 2022. The data of the research were searched in Anadolu University Library, Google Scholar, and Higher Education Institution Thesis databases with the keywords multiple disability, multiple disabilities, and additional disability. In this…

Preregistration involves researchers publicly registering key study elements before conducting a study to increase the transparency of research and limit the use and impact of questionable research practices. To support special education researchers' engagement with preregistrations, in this article we provide an overview of preregistration and…

Researchers in special education have been developing a knowledge base of evidence-based practices that improve the outcomes of students with disabilities. Unfortunately, filtering that knowledge into classrooms implemented by special education teachers has been a challenge. In "The Essentials of Special Education Research," Andrew M.…

Understanding experiences in online educational settings is crucial to improving teaching and learning. The purpose of this paper is to describe "Narrative Inquiry" as a research methodology that has the potential create the relational opportunities necessary to understand experiences in online learning environments. In this article, I…

High-quality systematic literature reviews provide a systematic process for identifying, synthesizing, and critiquing multiple studies and, in turn, inform theory, research, practice, and policy. With a focus on special education systematic reviews, we propose four core principles (i.e., coherence, contextualization, generativity, and…
