Manipulatives are widely considered an effective practice and have been recommended as an evidence-based practice for students identified with a learning disability when used within the concrete--representational--abstract instructional framework. The aim of the current study was to evaluate single-case experimental designs that implemented a…

Increasingly in K-12 schools, students are gaining access to computational thinking (CT) and computer science (CS). This access, however, is not always extended to students with disabilities. One way to increase CT and CS (CT/CS) exposure for students with disabilities is through preparing special education teachers to do so. In this study,…

In theory, both virtual manipulatives and explicit instruction are viable options to support students with disabilities as they learn mathematics. This study explored the effect of a treatment package--an app-based virtual manipulative (Cuisenaire® Rods) in conjunction with explicit instruction--on students' acquisition and generalization of…

While mathematics education is key to the post-school outcomes of students with disabilities, it has received less attention in research and practice compared with other aspects of educating this population. Skill maintenance is particularly crucial in mathematics because students build upon prior knowledge across grade levels. They also need to…

Mathematics instruction -- and interventions to support mathematics teaching -- for students with intellectual disability is important yet underexamined. This study explored a graduated instructional sequence referred to as the virtual-representational (VR) as a mathematical intervention. Researchers taught four students with disabilities what…

In this study, the authors examined middle school mathematics teachers' perceptions of their instructional practices with students with disabilities (SWDs) during face-to-face instruction before the COVID-19 pandemic and eLearning during the pandemic. A survey explored teachers' use of research-supported practices and the challenges and supports…

As K-12 mathematics standards shift toward emphasizing both conceptual and procedural knowledge in secondary courses such as algebra and geometry, the struggles for students with disabilities become more pronounced. To address these challenges, research has commonly explored the use of technology to aid in the teaching of students with…

Students with an intellectual disability historically faced exclusion in both schools and in their communities. Through court cases, legislation, and parental advocacy, students with an intellectual disability were awarded the right to an education, and under the Individuals with Disabilities Education Act, an education in the least restrictive…

Employment is an important postschool goal for students with mild intellectual disability; yet, results for this particular population are often not disaggregated from other disability categories. In this study, data from the National Longitudinal Transition Study-2 (NLTS2) were used to explore the extent to which students with mild intellectual…
