Background and Aims: Students with intellectual disability benefit from high-quality instruction in reading and mathematics. Methods: This Theoretical Paper outlines the need for effective, evidence-based instructional practices for this population and the potential for observation research to inform such advancements. We report our systematic…

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…

It is important for teachers and researchers to have access to evidence-based practices that target teaching specific content area skills, such as mathematics, to students with ASD (Hume et al., 2021). Previous literature reviews targeting mathematics interventions for students with ASD (Barnett & Cleary, 2016; Gevarter et al., 2016; King et…

Building proficiency with fraction arithmetic poses a consistent challenge for students with learning difficulties or disabilities in mathematics. This article illustrates how teachers can use the number line model to support struggling learners in making sense of fraction arithmetic. Number lines are a powerful tool that can be used to help…

Special education teacher training programs are increasingly addressing pedagogy for academic subjects, but little is known about how we are preparing teacher candidates to provide mathematics instruction and intervention to students with or at-risk for learning disabilities. The present study surveyed recent graduates (n = 48) on (1) types of…

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…

Fluency in math facts and procedures is critical for math achievement overall and often challenging for students with emotional and behavioral disorders to develop. This article describes how to implement two complementary and evidence-based practice strategies, incremental rehearsal and Cover-Copy-Compare, to build declarative and procedural…

Virtual manipulatives are increasingly being used to support students with autism spectrum disorder and intellectual and developmental disability (ASD/IDD), in mathematics. However, to date, virtual manipulatives have not been examined or classified as an evidence-based practice for students with ASD/IDD, despite classifications of virtual…

Researchers determined virtual manipulatives, on their own or as part of an instructional sequence, to be an evidence-based practice for students with intellectual and developmental disabilities (IDD; Long et al., 2022). Yet, the majority of research looking at virtual manipulative-based instructional sequences involves the phases learned in a…

Replications provide credibility by demonstrating under what conditions experimental findings can be repeated, the premise behind evidence-based practices. Replications in single-case research also investigate generalization of findings across groups. For groups with high variability, such as individuals with autism, assumptions of…

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…

This study examined the use of six math evidence-based practices (EBPs) for students in middle school with disabilities and sought to understand whether teachers' use of these practices was related to their confidence in implementation of EBPs or math teaching self-efficacy. I also examined differences between general and special education…

Students with disabilities are overrepresented in correctional settings in the United States and there is a dearth of information in the professional literature about the adequacy of instruction for these youth. Moreover, during the recent COVID-19 pandemic (2020-2022), access to education was abridged for many youth including those in juvenile…
