Experts laud the potential of educational technology (edtech) to promote reading among students with disabilities, but supporting evidence is lacking. This study evaluated the effectiveness of the Lexia® Core5® Reading edtech program (Core5) on the Measures of Academic Progress® (MAP) Growth Reading™ and easyCBM oral reading fluency performance of…

In intervention studies, high rates of "implementation fidelity" are important markers of a study's success; however, the definition of implementation fidelity is both complex and dynamic. In this synthesis, we examined the dimensions of implementation fidelity measured and reported in 99 studies in which researchers utilized a…

Children with developmental dyslexia (DD) display partially preserved morphology skills which they rely upon for reading and spelling. Therefore, we conducted explicit and intensive training of derivational morphology in French and Swiss individuals with DD, ages 9 to 14 years, in order to assess its effect on: morphological awareness, reading…

School context can shape relative intervention response in myriad ways due to factors, such as instructional quality, resource allocation, peer effects, and correlations between the school context and characteristics of enrolled students (e.g., higher-poverty students attending higher-poverty schools). In the current study, we used data from…

In a multiyear, multisite, randomized control trial, we examined the effects of comprehensive professional development designed to support teachers' data-based instruction (DBI) for students with intensive early writing needs. Teachers (N = 154; primarily special educators or intervention specialists) were assigned randomly to a treatment group (n…

We examined whether a Phonics + Set for Variability (SfV) reading intervention would lead to better irregular word reading compared to Phonics + Morphology within a cluster randomized control trial (RCT) design with a follow-up measurement. The participants were 273 Grades 2 and 3 students with reading difficulties (139 in the Phonics + SfV and…

We examined the efficacy of a Technology-Based Early Language Comprehension Intervention (TeLCI) designed to teach inferencing in a non-reading context. A group of Grades 1 and 2 students from 2 elementary schools in the U.S. Midwest identified as at risk of comprehension difficulties were assigned randomly to a business-as-usual control group or…

The purpose of this review was to synthesize research on the effect of professional development (PD) targeting data-based decision-making processes on teachers' knowledge, skills, and self-efficacy related to curriculum-based measurement (CBM) and data-based decision-making (DBDM). To be eligible for this review, studies had to: (1) be published…

Executive function (EF) training has shown promise for remedying general EF deficiencies faced by students with mathematics difficulty (MD) and for improving their performance. However, latest research also suggests that the instant and sustained effects of EF training remain inconsistent. In this study, 32 Chinese students with MD, age 7 to 10…

Preschool-age children identified as at risk for later reading difficulties can benefit from supplemental, small-group emergent literacy intervention. As such interventions become commercially available and marketed to preschool programs, it is important to understand their impacts when implemented by intended end users under routine conditions.…

We evaluate the direct and inferential mediation (DIME) model for reading comprehension with a sample of struggling readers in Grades 3 to 5 (N = 364) in the context of a large-scale randomized controlled trial (RCT) investigating two theoretically distinct reading interventions (text processing + foundational skills [n = 117] or text processing…

Teachers' implementation of differentiated supplemental instruction is critical to help students with or at risk for reading-related disabilities acquire early reading and vocabulary skills. This study represents an initial investigation of whether classroom teachers' intervention fidelity (exposure, adherence, and quality) of targeted reading…

The adoption and sustainability of evidence-based Tier 1 literacy practices in secondary content-area classes is important to improve reading success for students with learning disabilities. We conducted an exploratory multiple-case study investigating teachers' adoption and sustained use of evidence-based Tier 1 literacy practices that benefit…

To address the needs of a diverse group of students with reading difficulties, a majority of researchers over the last decade have designed and implemented multicomponent reading interventions (MCRIs) that provide instruction in multiple areas of reading yielding mixed results. The current study evaluates whether students' baseline word reading…

A concerning number of students enter kindergarten facing an intractable variation of mathematics difficulties (MD). This study investigated the impact of an explicit, core kindergarten mathematics program on the mathematical outcomes of kindergartners who demonstrated risk for severe MD at kindergarten entry and examined whether these students…
