Students with disabilities are often included in general education social studies classes, but these classes can differ in the achievement level of the overall class, including wide variation in content-related background knowledge, reading achievement, or both. The purpose of this study was to examine how background knowledge and reading…

Because of the importance of teaching reading comprehension to struggling young readers and the infrequency with which it has been implemented and evaluated, we designed a comprehensive first-grade reading comprehension program. We conducted a component analysis of the program's decoding/fluency and reading comprehension dimensions (DF and COMP),…

A common theme uniting articles in this special issue is a focus on aptitude-by-treatment interactions (ATIs). This timely and welcome focus allows the field to synthesize current substantive findings on ATIs in educational intervention research in both reading and math domains. In this methodological commentary, we begin by reviewing traditional…

Researchers have investigated the simultaneous prompting (SP) procedure across three decades; however, no meta-analysis has been conducted. In the present systematic review, we conducted both a descriptive and meta-analysis of SP studies from a seminal publication of an SP study through 2017. Our search resulted in 20 studies published in English…

In the current study we examined the effect of a self-regulated strategy development intervention on the fraction calculations of students with or at risk for disabilities using a multiple-baseline-across-sites, single-case design. Specifically, the intervention package addressed the following skills: adding and subtracting fractions with unlike…

Proficiency with fractions is one of the most significant predictors of later mathematics achievement. However, there are currently no meta-analyses that assess the literature base on fractions for students with or at risk for disabilities using quality indicators. We applied the 2014 Council for Exceptional Children Standards for Evidence-Based…

A tenet of multitiered systems of support and response to intervention (MTSS-RTI) is that lack of response to instructional intervention is explained by classroom experiences and behaviors given opportunities to learn. We investigated the potential of filling this information gap in MTSS-RTI decision making using ecobehavioral observation to…

Federal policies have aimed to improve access to grade-level curriculum for students with disabilities (SWD). Current conceptualizations of access posit that it is evidenced by students' academic outcomes. In a meta-analysis of 180 effect sizes from 23 studies, we examined access as outcomes by estimating the size of the gap in reading achievement…

Empirical studies investigating supplemental reading interventions for students with or at risk for reading disabilities in the early elementary grades have demonstrated a range of effect sizes. Identifying the findings from high-quality research can provide greater certainty of findings related to the effectiveness of supplemental reading…

This study examined the role of initial skill in moderating intervention effects of a 50-lesson mathematics intervention program, ROOTS, for at-risk kindergarten students focused on developing whole-number concepts and skills. The study utilized a randomized block design with at-risk students (n = 592) within classrooms (n = 60) randomly assigned…

In this article, we describe results of a reanalysis of two randomized studies that tested the effects of enhanced anchored instruction (EAI) on the fractions computation performance of students in special education resource rooms and inclusive mathematics classrooms. Latent class analysis and latent transition analysis classified students…

Research about students with disabilities and students identifying as LGBQ (lesbian, gay, bisexual, or questioning) reveals that both populations report more suicidality and peer victimization and less school connectedness than do their peers. No study has previously examined the intersection of these identities with regard to peer victimization,…

We conducted a randomized controlled potential efficacy trial to examine effects of two variants of the Tools for Teachers (TfT) professional development (PD) intervention on preschool teachers' implementation of embedded instruction practices and children's developmental and learning outcomes. Thirty-six preschool teachers recruited from three…

Nonacademic skills related to college and career readiness (CCR) have become more prevalent in the literature as proposed conceptual models and frameworks, yet little empirical research exists in their support. We employed latent variable modeling to empirically test a previously proposed six-domain framework of CCR for adolescents with and…

In this article, we analyze the Supreme Court's decision in "Endrew F. v. Douglas County School District RE-1" (2017), interpreting the Individuals with Disabilities Education Act (IDEA) and its provisions creating a right of every student with a disability to have an appropriate education. We compare the "Endrew" decision with…
