Special education teachers of color are underrepresented in research about attrition and retention, despite evidence of their role in the academic, social, and emotional success of students of color. We used critical quantitative methods and structural equation modeling to investigate the attrition and retention variability between special…

Schema instruction improves word-problem solving for students with mathematics difficulty (MD; e.g., Powell et al., 2015); however, prior research suggests that students need word-problem-specific language comprehension in addition to schema knowledge to build word-problem models (Fuchs et al., 2015, 2018). Students have general word knowledge…

This study's first purpose was to investigate effects of a fourth- and fifth-grade "next-generation" fraction intervention, which included six enhancements over a previously validated fraction intervention, designed to address career- and college-readiness standards. The study's second purpose was to assess effects of the next-generation…

The purpose of this study was to examine the efficacy of a teacher-implemented professional development program to increase the fidelity with which paraeducators use evidence-based practices (EBPs) in instruction for children with autism. Employing a modified multiple-probe design, investigators implemented the Autism Focused Intervention…

Executive function (EF), a set of neurocognitive processes, is central to students' emotional and behavioral well-being. Despite students with emotional and behavioral disorders (EBD) being at risk for negative long-term outcomes, there is a paucity of EF research with students at risk for EBD in early elementary school, an important…

Open practices, such as preregistration, registered reports, open materials, open data, open analytic code, replication, open peer review, open access, and conflict-of-interest and funding statements, support the transparency, accessibility, and reproducibility of research and other scholarship. The purpose of this review was to examine the…

Evidence-based assessment (EBA) requires that investigators employ scientific theories and research findings to guide decisions about what domains to measure, how and when to measure them, and how to make decisions and interpret results. To implement EBA, investigators need high-quality assessment tools along with evidence-based processes. We…

Qualitative research (QR) has gained visibility and acceptance in the field of special education due to early efforts to identify quality indicators focused on technical and methodological aspects of QR. Whereas these indicators focused on credibility and trustworthiness of data, this article articulates additional QR quality indicators to enhance…

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…

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…

Secondary data analyses occur when new analyses are proposed for existing data. Although they are prevalent in special education research, there is little guidance on how to prepare secondary data analyses studies. Preregistration of secondary data analyses studies provides a nice opportunity and structure for fellow researchers to share…

Single-case design has a long history of use for assessing intervention effectiveness for children with disabilities. Although these designs have been widely employed for more than 50 years, recent years have been especially dynamic in terms of growth in the use of single-case design and application of standards designed to improve the validity…

Group design research studies can provide evidence to draw conclusions about "what works," "for whom," and "under what conditions" in special education. The quality indicators introduced by Gersten and colleagues (2005) have contributed to increased rigor in group design research, which has provided substantial…

Children with complex communication needs (CCN) who use augmentative and alternative communication (AAC) often need more time to process and respond when communicating with others. This study employed a survival analysis approach exploring child response-time patterns following different communication opportunities for young children with CCN who…

The formula used to allocate federal funding to states for special education is one of IDEA's most critical components. The formula serves as the primary mechanism for dividing available federal dollars among states and represents policy makers' intent to equalize educational opportunities for students with disabilities nationwide. In this study,…
