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…

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…

The purpose of this study was to identify the different profiles and patterns of progress in numerical skills of 6- to 10-year-old elementary school students with mild or moderate intellectual disability (ID). A standardised test of numerical and arithmetic skills was administered to 57 students with ID at the beginning and at the end of a school…

The purpose of this study was to investigate the effects of using an iPad to teach early literacy skills to students with intellectual disability (ID). Three elementary students with mild to moderate levels of ID participated in the study. We used a multiple-probe design across students to examine a functional relationship between using an iPad…

This study examines the effects of a working memory (WM) sensitive math intervention in students with learning disabilities (LD). The intervention aims to improve early mathematical competencies while accounting for weak cognitive resources through a reduced instructional design. These principles are considered to be effective for learning. Ten…

Learning prepositions is very important for students with an intellectual disability to engage in functional communication behaviors. In addition, it is important for the students with intellectual disability to engage in physical activity at school because they spend the majority of their waking hours during weekdays at school. One way to…

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…

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…

This study used a single-subject alternating treatment design across students to compare mass discrete trials and distributed mass trials distributed in a shared story reading on the acquisition of functional skills for students with Autism. The results of this study examined a functional relationship between the interventions on the acquisition…

The present study sought to determine if systematically teaching the use of visual supports to three students identified as having moderate to severe disabilities resulted in improved task completion and independence in general education settings. For each participant, a visual support system delineated a multi-step task, which prior to the…

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.…

Background: This study evaluated the impact of a structured 10-didactic units intervention on promoting the school inclusion of elementary school students with intellectual disability (ID). Method: The intervention was devised for 152 Italian typically developing (TD) elementary school students that were randomly assigned to the experimental (EG)…

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…
