In this study, we used an instructional package consisting of a constant time delay procedure with multiple exemplars to teach five elementary students with moderate intellectual disability to identify geometric shapes listed in their state's core content standards and included on their state's alternate assessment. In addition, we included four…

Modified schema-based instruction (MSBI) is a strategy to teach mathematical word problem solving to students with moderate and severe disabilities (MSD). In this comprehensive review, we explore the current state of research on MSBI to determine whether MSBI is an evidence-based practice (EBP) for students with MSD. We reviewed 12 studies, of…

The purpose of this review was to examine the body of research on teaching mathematics to students with moderate and severe developmental disability that has been published since 2005, reflecting changes in both the academic expectations for this population and research and design standards in the evidence-based practice (EBP) era. We examined…

A multiple probe across participants design was used to examine the effectiveness of a treatment package to teach students with moderate intellectual disability how to solve simple linear equations. The investigator read realistic scenarios of a problem, used actual items as manipulatives, presented a visual aid of the equation, and used a system…

Instructional technology is growing at rapid rates. In the field of mathematics, virtual manipulatives are a research-based tool that has shown to have a positive impact on students' mathematic achievement, as well as student engagement in learning. In an effort to extend the research, this study investigated the impact of virtual manipulatives,…

Academic performance for students with moderate to severe disabilities falls far behind their typically developing peers and puts them at risk for continued dependence after school ends. Video prompting is an evidence-based practice that has been used to teach various nonacademic skills; however, few studies have focused on using video prompting…

Educational programs for students with moderate and severe disabilities (MSD) have undergone drastic changes since the mandate for access to the general curriculum was provided by Individuals With Disabilities Education Act. Since then, educators have struggled to find methods to use to promote optimal learning, including in the area of…

This study evaluated an intervention developed through an Institute of Education Sciences-funded Goal 2 research project to teach students with moderate intellectual disability (moderate ID) to solve addition and subtraction word problems. The intervention involved modified schema-based instruction that embedded effective practices (e.g.,…

Price comparison is a functional mathematics skill involving purchasing, use of money, and budgeting, with the goal of selecting the best deal based on a person's financial resources (Browder, Spooner, & Trela, 2011). The operational definition of "price comparison" is to compare the magnitudes of the price numbers and then select…
