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…

The success of teachers is tied to their effectiveness in managing student behavior. In this meta-analysis, we identified 49 single-case-design studies that evaluated the effectiveness of teacher training on their implementation of behavioral support strategies. Training was most often provided in a one-on-one format (n = 18) and included ongoing…

In this secondary analysis of a previously conducted systematic review, we analyze social validity assessments in intervention research for transition-age autistic youth. Social validity is concerned with the acceptability of the intervention goals, the acceptability and feasibility of the intervention procedures, and the perceived importance of…

In this preregistered study, we confirmed a transition-planning construct and determined its relationship with an established economic-hardship construct using parent- and youth-reported data from the National Longitudinal Transition Study 2012 and following established quality indicators of preregistered secondary data analyses studies.…

The central obligation under the Individuals With Disabilities Education Act is to provide each eligible student with a free appropriate public education (FAPE). In "Endrew F. v. Douglas County School District RE-1" (2017), the U.S. Supreme Court revised the prior substantive standard for determining FAPE that the court had developed in…

As more schools adopt inclusive practices, the need for schools to understand how students perceive these practices grows. The current study explores K-12 students' perceptions of co-teaching through a systematic review and thematic analysis of the literature. Through an analysis of quantitative, qualitative, and mixed-methods research from…

The effectiveness of Tier 2 interventions may depend on the variability of student skills within an intervention group. We investigated the effect of pretest variability within intervention groups using data from a large-scale study of ROOTS, a Tier 2 kindergarten mathematics intervention. Our research questions were as follows: Does mathematics…

One of the most well-known instructional methods used to enhance Chinese character reading (CCR) is Chinese stem-deriving instruction (CSDI). In this method, CCR is taught via a group of characters (e.g., [foreign character omitted], [foreign character omitted], and [foreign character omitted]) that share the same stem (e.g., [foreign character…

As instructional leaders, principals establish a vision of effective instruction in their schools and support that vision through evaluation and development efforts. Thus, their beliefs about instruction in special education may have direct consequences for special educators and their students. Though research suggests principals lack experience…

The purpose of this quantitative systematic literature review was to identify and describe published mathematics studies from 1980 to 2021 that incorporated a self-monitoring component (k = 22 studies; N = 1,787 students). We examined specific self-monitoring procedures, instructional contexts, implementation variables, and methodological quality.…

Under federal law, parents have the right to decline, or waive, English language support services when their child is identified as an English learner (EL) in school. In this study, we focus on this important subgroup of ELs--referred to as waived ELs--at the understudied intersection of EL status and special education (SPED) status. Using…

Youth with and at risk for disabilities served in alternative education settings frequently struggle with the writing process, which impedes their ability to communicate ideas and opinions with others. Providing explicit teaching of a writing strategy is necessary for this population of youth. This study examined the effects of self-regulated…

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…
