The purpose of the study was to compare the differential effects of response independent and response-dependent criteria used to determine when to increase to the next delay interval in the progressive time delay (PTD) procedure. An adapted alternating treatments design was used to evaluate the relative efficiency of three variations of the PTD…

This study examined the effect of information and communication technologies (ICTs) on intellectually disabled children's academic achievement in teaching mathematics. Hundred children with mild to moderate levels of intellectual disability participated in a four-week experiment in two groups. The results showed that (1) the experimental group…

This study compares the effectiveness and efficiency of constant time delay (CTD) and simultaneous prompting (SP) to teach decoding and word reading to four students, 7 to 9 years of age, with intellectual disabilities (ID) in the mild to moderate range. An adapted alternating treatment design was implemented to assess the two methods. The results…

Efficient vocational skills instruction is needed to meet the needs of a growing number of job seekers with intellectual and developmental disabilities (IDD). This study examined the effects of self-directed video prompting used to teach transition-age students with IDD chained vocational tasks. A multiple probe design across behaviors was…

Students with intellectual disability often receive limited explicit instruction in comprehension strategies. The current study evaluated the effects of a multi-component literacy intervention designed to improve comprehension of high school students with moderate intellectual disability on adapted expository science text. The multi-component…

The aim of this research was to study the effectiveness of teaching with the simultaneous prompting in teaching students with intellectual disabilities attending the vocational education center and their ability to fold towels. Multiple baseline models with inter-subject probe stage, which is one of the single-subject research methods, has been…

School psychologists are well-positioned to assist practitioners in engaging students in physical activity (PA) which can increase student access to improved well-being and associated health benefits. This may be of particular importance for adolescents with moderate to severe developmental disabilities (DD; autism and intellectual disability) who…

Objective: The effects of hemsball game skills development program on the motor proficiency level of children in the 12-16 age group with mild and moderate intellectual disabilities (ID) have been examined in this study. Method: A total of 50 (25 experimental group +25 control group) students, 23 of which had mild intellectual disabilities (ID)…

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…

The purpose of the study was to evaluate the effects of a system of least prompts procedure and use of a graphic organizer to teach the academic literacy standard of comparing characters in text for elementary students with moderate and severe intellectual disability. A multiple probe across participants design was used to evaluate the results.…

Students with significant intellectual and developmental disabilities deserve access to instruction on academic skills in addition to functional skills. Many teachers, however, report challenges with identifying appropriate evidence-based practices to teach academics to these students. The purpose of this systematic review was to summarize and…

The current study was conducted in Taiwan to examine the effectiveness of using a self-monitoring strategy to increase the percentage of completion of classroom tasks for three high school seniors with moderate intellectual disability. We used a multiple-probe-across-subjects single-case design to evaluate the use of a self-monitoring tool to…

This study examined the effects of a treatment package that combined technology-based supports and systematic instruction on the comprehension skills of elementary-aged students with moderate intellectual disability. Researchers used a multiple probe across participants design. Specifically, researchers examined the effects of constant time delay…
