The current scoping review synthesizes the literature on interventions targeting anxiety in individuals with a learning disability (LD). Specifically, the review identifies types of interventions, outcomes, and barriers to or facilitators of implementation of interventions by school staff. The available literature was analyzed using a descriptive…

This quasi-experimental study was designed to investigate the initial efficacy of a fraction-vocabulary intervention for Grade 4 students with mathematics difficulty (MD) and to explore its impact on relevant fraction competencies. Thirty-three students were assigned to either the intervention condition (n = 16) or a business-as-usual comparison…

This pilot study examined the feasibility of using worked examples as a mechanism to improve verbal explanations of fractions concepts among Grade 5 students with mathematics difficulties in a small-scale randomized controlled trial (RCT) before scaling up to a large-scale RCT. Students (N = 49) were randomly assigned to a business-as-usual (BAU)…

Counting is foundational to success with mathematics. In this synthesis, we analyzed 17 studies about counting-focused interventions for preschool and kindergarten students with mathematics difficulty or at-risk of mathematics difficulty. All interventions addressed several components of counting, including stable order, one-to-one correspondence,…

This study examined the effect of comprehension strategy instruction on third-grade English Learners' word-problem-solving performance. The supplemental intervention included modeling how to read the word problem to identify and restate the question, distinguishing relevant from irrelevant information, and collaborating with peers on applying the…

We quantitatively synthesized findings of quasi-experimental and randomized control studies of interventions designed to improve the mathematics achievement of secondary school students with mathematics difficulties (MD). We identified 45 studies (49 interventions) published between 1978 and 2020 and classified interventions into five categories:…

This study examined how word-problem characteristics influenced students' learning and retention of word-problem knowledge during and after an intervention. The participants were 221 fourth-grade students (average age at pretest = 8.8 years) who experienced word-problem difficulties (WPD) and had received a word-problem intervention in third…

This study examined an intervention program designed to enhance reading comprehension among struggling readers from low socioeconomic backgrounds by improving their understanding of word structure and meaning. Delivered by college education students, the program targeted second-grade students. Change scores in morphological awareness (MA),…

As students enter the upper elementary grades, word problems become a main component of mathematics instruction, increasing in complexity as students advance through the curriculum. For students identified as emergent bilinguals with mathematics difficulty (MD), the linguistic complexity inherent in word problems may serve as a barrier to…

The effectiveness of a morphological awareness (MA) intervention program on reading fluency and accuracy performance was examined in 40 students with reading disabilities in fourth to sixth grade, ranging in age from nine to 12 years old (M = 10.51, SD = 0.89). The study used an experimental pre-post design consisting of a morphological…

Students with disabilities who display severe reading difficulties may require intensive interventions in order to make progress. The purpose of this study is to examine the effects of a multicomponent reading intervention implemented at two different intensities, in two separate randomized control trials, for a subset of fourth-grade students who…

A formative pilot study of a fractions intervention was conducted to address the intervention's potential for improving fifth-grade struggling students' knowledge of fractions, and to identify any logistical or instructional design issues, before scaling up for a randomized control trial. In the first section, we provide details of the formative…

Legislations mandates that educators use evidence-based practices (EBPs) that are supported by scientifically based research. EBPs have demonstrated a likelihood to work for students with disabilities. EBPs should match targeted needs of the student receiving the instruction, which sometimes requires educators to search for the best intervention…

The use of data for adaptive, tailor-made education can be beneficial for students with learning difficulties. While evaluating the effects of a data-based decision-making (DBDM) intervention on student outcomes, considerable variation between intervention effects, ranging from high-intervention effects to small or even negative intervention…

We use three data sources to build a rationale for why intensive interventions are necessary for students with pervasive reading disabilities: current data on the performance of students with disabilities on reading achievement measures over time, observation studies on students with reading disabilities in general and special education…
