We synthesized studies published since 2000 that assessed the effects of using virtual manipulatives to increase the mathematical accuracy of students with disabilities. We extracted a total of 1,796 raw data points from 114 cases across 35 single-case studies. By applying three-level multilevel modeling, we analyzed both immediate effects and…

This meta-analysis synthesized over 40 years of research (k = 42 studies) in the social studies for students with learning disabilities. We analyzed the various mechanisms that researchers have used to improve outcomes in the social studies by conducting a subgroup investigation of interventions targeting the following instructional categories:…

In this article, we describe results of a reanalysis of two randomized studies that tested the effects of enhanced anchored instruction (EAI) on the fractions computation performance of students in special education resource rooms and inclusive mathematics classrooms. Latent class analysis and latent transition analysis classified students…

Transportation access is a major contributor to independence, productivity, and societal inclusion for individuals with intellectual and development disabilities (IDD). This study examined the effects of pedestrian navigation training using picture prompts displayed through a video iPod on travel route completion with 4 adults and IDD. Results…

This study examined the effects of online reading instruction for at-risk fourth-grade students in Philadelphia. The authors used a multiple baseline design to assess the extent to which the students increased their oral reading rate given systematic supplemental online reading instruction. Tutoring consisted of 4 sessions per week with 50-min…
