This dissertation explores the theme of applying video-based instruction on employment skill acquisition among secondary students with intellectual and developmental disabilities (IDD). It consists of an introduction, three stand-alone papers, and a research statement. Chapter 1 presents the overview of the current competitive integrated…

Individuals with intellectual and developmental disabilities (IDD) have a significantly lower employment rate than those without disabilities. One promising intervention for improving employment outcomes is video-based instruction. The purpose of this systematic review was to examine the application of video-based instruction (VBI) to teach…

Sexuality education (SE) for individuals with intellectual and developmental disabilities is needed, but is sparse. Seven individuals with intellectual and developmental disabilities and two educators participated in a mixed method participatory design to iteratively refine nine learning activities for SE. We analyzed usability, usefulness, and…

This meta-analysis analyzed 39 studies that met the inclusion criteria for employment-related interventions for individuals with developmental disabilities. Each experiment included in this analysis either met or met with reservations all of the basic design standards (Kratochwill et al. 2010, 2013). Tau-U effect sizes were calculated for each…

Instructional technology plays a role in supporting access to and meaningful participation in general education curriculum for students with developmental disabilities in inclusive classrooms. In this study, two 18-year-old students with developmental disabilities received technology-supported instruction to assist with learning the content in…

Research suggests that high school aged individuals with developmental disabilities are at a higher likelihood of lacking the prosocial behaviors necessary for successful transition into post high school life and a work environment. Decreased vocational success often leads to increased likelihood of mental health issues for individuals with…

Recent research has shown the effectiveness of literacy-based behavioral interventions (LBBIs) as an instructional strategy for a host of skills and routines, including employment skills. This study compared the effects of three LBBI storybook formats (print, e-book, and e-book enhanced with video clips) on the accuracy and independent completion…

The process of training special education teacher candidates is an issue that has been widely discussed in literature, yet there is no consensus as to the most effective method. Therefore, it is recommended that methods designed to meet the needs of special education teacher candidates with proven efficiency should be used collectively. This…

The ability to engage in positive social interactions is an important goal for young children with developmental disabilities (DDs). Peer-mediated intervention (PMI), one category of interventions often employed with those who show social skill deficits, involves use of typical peers who live model appropriate behaviors. A second frequent category…

During early childhood, practitioners and family members are often tasked with determining optimal approaches to support social skill development in young children with developmental disabilities in inclusive and self-contained settings. Eight different evidence based approaches are highlighted (social narratives, scripting, pivotal response…

Introduction: According to the World Health Organization, sexuality education (SE) is considered a human right and aims to increase understanding, decrease abuse, unplanned pregnancies, and sexually transmitted infections. Yet, individuals with intellectual or developmental disabilities are less likely to receive or SE is primarily focused on…

This study investigated the effectiveness of video self-modeling (VSM) for eliminating the public undressing of two elementary-aged students with developmental disabilities during urination. A multiple-probe design across participants revealed that the degree of exposed body parts decreased immediately after introduction of VSM. However, exposure…

A primary goal of instruction for students with developmental disabilities is to enhance their future quality of life by promoting skill acquisition, which will enable them to live, function, and participate in the community. One instructional method that can help students with developmental disabilities improve independence in performing daily…

Effective vocational instruction is an essential aspect of preparing students with intellectual and developmental disabilities (IDD) for the world of work. We systematically reviewed research on instructional methods used to teach employment skills to secondary students with IDD. We identified 56 studies involving 766 participants with IDD. Four…

The present study replicates and extends previous research on the use of video modeling (VM) with voiceover instruction to train staff to implement discrete-trial instruction (DTI). After staff trainees reached the mastery criterion when teaching an adult confederate with VM, they taught a child with a developmental disability using DTI. The…
