Fractions are an important concept used throughout advanced mathematical ideas and everyday life. Students need a solid understanding of fraction concepts, such as magnitude, equivalence, and operations. However, many students, including students with learning disabilities (LD) in mathematics, struggle with fractions. In this article, the use of…

Given the interdisciplinary influences on school psychology along with its requirement to comply with federal and state law in the United States, scientific progress in the area of cognitive assessment and specific learning disabilities (SLD) identification has experienced slow, if not stagnant, progress. Extrapolation of research from one…

This article reports on a project implemented to help middle school teachers provide evidence-based instruction and intervention to students with mathematics learning disabilities (MLD) and mathematics difficulties (MD). Multiple sources--interviews, surveys, and field notes from formal and informal observations--were used to gather data on…

Video Modeling (VM) is one of the most widely used approaches by researchers to improve many skills, such as academic skills in students with Learning Disabilities (LD; Boon et al., 2020). As the incidence rate of individuals with LD in Saudi Arabia increase (Almedlij & Rubinstein-Avila, 2018), the need for evidence-based math interventions…

Students with learning disabilities in word-level reading typically require explicit, systematic, and intensive phonics intervention. Teachers' capacity to provide effective intervention depends largely on their depth of understanding of language and their proficiency with evidence-based instructional methods. This article outlines the key…

The specific problem examined by this study was that it is unknown if and to what extent there is a relationship between mathematics teachers' attitudes towards inclusion of students with learning disabilities in math and teachers' attitudes towards using evidence-based practices to improve mathematics achievement for this population. Therefore,…

This study used data from the U.S. state of Michigan schools participating in the "Reading First" program to examine the stability of students' disability status in Grades 1 to 3. Reading First aimed to improve at-risk students' reading comprehension through research-based instruction. We analyzed how changes in students' disability…

The field of specific learning disabilities (SLDs) has faced three kinds of challenges. "Constitutional challenges" arise from classification and definitional complexities, identification issues, comorbidity, and ontological debates. "Internal challenges" include the inherent difficulties of scientific thinking that compete…

Single-case designs substantiate the effectiveness of interventions for people with disabilities and other populations through the repeated measurement of behavior over time. Consequently, employing accurate and reliable systems of measurement is critical to the validity of single-case designs. Much of the data in single-case research are…

Developmental dyscalculia (DD) affects 2-6% of the population. Yet, a readily accessible list of potential interventions for DD is not available or can be easily found by educators. With a large percentage of the population afflicted with DD, educators should be made aware of what supportive approaches are available. The purpose of this study was…

The purpose of this article was to evaluate the quality of research studies and the evidence base for algebra instruction for secondary students with learning disabilities (LD) from 2000 to 2020. We evaluated the quality of methodological rigor of a total of eight single subject and three group design research studies using the 2014 Council for…

The purpose of this study was to investigate Access Arrangements (AA) which allow students with specific learning difficulties (SpLDs), disabilities or medical needs to access assessments by making "reasonable" adjustments, as established by the Equality Act 2010. A review of the literature revealed some problematic issues relating to…

Meta-analysis is one approach for synthesizing research studies to identify generally effective instructional practices for students with learning disabilities (LD). In this article, we define core components of meta-analytic literature reviews, discuss how to interpret findings from meta-analyses, and provide guidelines for how research consumers…

Evidence-based instructional strategies in mathematics provide critical support related to academic achievement for students with disabilities. Data from national achievement assessments suggest that students with disabilities' academic growth in mathematics stagnates at the secondary level. Given that the majority of previously researched…

It is imperative teachers use evidence-based practices to instruct all learners. Yet, there are limited reviews focused on educational practices to support secondary students with learning disabilities in algebra. This evidence-based systematic review focused on research published in peer review journals between 1999 and 2019. Eighteen studies…
