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 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…

Parental involvement plays a vital role in the transition from kindergarten to primary school among children with intellectual and developmental disabilities (IDDs); this study aims to explore Chinese parents' experiences of parental involvement during this period. Informed by interpretive phenomenological analysis, semi-structured, one-on-one…

In response to the demand for adopting a social justice system to manage students' challenging behaviors, many countries are implementing positive behavior support (PBS) programs at the school level. However, the use of PBS in Saudi Arabian schools is still a goal rather than reality. It is strongly evident that school-wide PBS can be applicable…

In this dissertation I report findings from two studies of the literacy abilities of children with Williams syndrome (WS), a genetic disorder associated with intellectual disability. I had two overarching goals: 1) evaluate the applicability of theories of reading and spelling acquisition developed based on typically developing children to…

Sight-word interventions are often implemented when students show delays in word recognition. However, few studies have investigated the effects of teaching sight words using phrases. The current study investigated the effects of a tablet-based flashcard intervention on the acquisition of sight phrases. A multiple-baseline design across word sets…

Students with significant disabilities often attend general education (mainstream) classrooms, yet they are not receiving adequate support to experience full school participation. This qualitative case study was conducted to explore how key intrinsic (i.e. personal skills and abilities) and extrinsic (i.e. environmental) factors influence the…

The purpose of this study is to analyze the various characteristics of teacher's question to find out whether teachers who teach STEAM classes are conducting effective classes that can stimulate creativity and improve problem-solving skills. For the purpose of the study, the video recording data of the 8th hour of the STEAM class by two special…

A single subject multiple probe design across participants was used to examine the effects of distributing trials in shared stories on listening comprehension and skill acquisition with students with significant cognitive disability (SCD). The results suggest a functional relationship between the independent and each of the dependent variables. In…

Students with intellectual and developmental disabilities (IDD) are likely to experience writing challenges that can negatively impact their overall academic, vocational, and social success. The goals of this study were to determine what writing interventions have been used with students with IDD, how their writing skills have been measured, the…

Some statewide testing programs allow students to receive corrective feedback and revise their answers during testing. Despite its pedagogical benefits, the effects of providing revision opportunities remain unknown in the context of alternate assessments. Therefore, this study examined student data from a large-scale alternate assessment that…

The purpose of this research study was to prove if students who are intellectually disabled can obtain phonemic awareness and the ability to read independently with the use of Wilson's Fundations. This study aims to investigate if students who have been identified as intellectually disabled are able to gain phonemic awareness by using Wilson's…

Purpose: The present study investigated school absence among 1,076 5-15 year-old children with neurodevelopmental conditions (intellectual disability and/or autism) approximately one year following the start of COVID-19 in the UK. Methods: Parents completed an online survey indicating whether their child was absent from school during May 2021 and…

Small group instruction in classrooms provides children opportunities to collaborate on academic tasks, as well as opportunities for social interactions. Although such arrangements are common for children with typical development, children with moderate to severe disabilities (MSD) may receive few or no opportunities to participate meaningfully in…

This study explored the perceptions of special education teachers of students with intellectual disabilities at three elementary schools in Saudi Arabia regarding the instructional practices and content used for teaching such students mathematics. The research employed a qualitative multiple case study design and used an open-ended questionnaire,…
