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,…

Number comparison is a fundamental skill required for academic and functional mathematics (e.g., time, money, purchasing) for students with disabilities. The most commonly used method to teach number comparison is number lines. Although historically paper number lines are used, app-based number lines may offer greater flexibility. This study…
