Awareness of autism is rising, yet social determinants of health continue to impact rates, ages of diagnosis, and diagnostic load. Different psychiatric labels carry stigmas; unequal rates of diagnoses may indicate biases in the healthcare system. This study investigates six prior diagnoses (ADHD, disorders of conduct, adjustment, anxiety, mood,…

The purpose of this dissertation was to extend the literature base for teaching students with intellectual and developmental disabilities (IDD) mathematics and self-determination skills using an evidence-based practice called modified schema-based instruction (MSBI). Chapter one provides the rationale for teaching both mathematics and…

This study aimed to use a game-based learning (GBL) module with multi-scaffolding and mobile technology for high school students with mild intellectual disabilities (MID) to assist them in learning career education knowledge. This study used a quasi-experimental method to investigate the participants' learning effectiveness, motivation, flow…

Special education has changed over the years since its inception due to advocacy, litigation, legislation, trends, and research investigations. While it can be somewhat controversial depending on the disability the child might have or professionals involved in the process of instructing and planning his/her future education, it is a field that has…

Historical reasoning, as a disciplinary literacy, aims to develop higher-order thinking in addition to depth of historical knowledge beyond the textbook and memorization of facts. It teaches students to use information across multiple sources to contextualize and corroborate historical accounts, constructing an informed yet critical interpretation…

The problem that was addressed in this study was that students with severe intellectual disabilities (SwSID) enrolled in life skills settings are not receiving adequate transition planning services at local rural public schools in a southwestern state. The purpose of this study was to investigate special education teachers' (SET) perceptions about…

Children must describe maltreatment coherently for their testimony to be influential in court. We know little about how well children with intellectual disabilities (CWID) describe their experiences relative to typically developing (TD) children, despite CWID's vulnerability to maltreatment. We investigated children's reports of an experienced…

Background: The prevalence of obesity among individuals with intellectual and developmental disabilities (IDD) is equal to or greater than the general population. Methods: Overweight/obese adults (BMI =25 kg/m2) with mild-to-moderate intellectual and developmental disabilities were randomized to an enhanced stop light diet…

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…

Background: Even though participation of people with intellectual disabilities in research is increasingly common, there is little insight into how many people with intellectual disabilities participate, their motivations to participate and their interests regarding study results. Method: Five questions were added to the Panel Living Together…

Background: The study asks when does inclusive research add value? The authors argue that this is important, given the additional time and cost of co-researching with people with intellectual disabilities. The study is situated in debates about a "second generation" of inclusive research which advocates focussing more on outcomes than…

Standardized cognitive and educational assessments of individuals with intellectual disability (ID) provide crucial information for parents, researchers, and educators. Understanding the unique developmental strengths and challenges of an individual with ID is imperative to determining appropriate educational placements, developing intervention…

This intervention report presents findings from a systematic review of the System of Least Prompts (SLP) conducted using the WWC Procedures and Standards Handbook (version 3.0) and the Children and Students with Intellectual Disability review protocol (version 3.1). No studies of SLP that fall within the scope of the Children and Students with…

The problems associated with undue and overbroad guardianship for people with intellectual and developmental disability (IDD) have received increasing attention in recent years. In simple terms, guardianship threatens one's ability to exercise self-determination and make important decisions that reflect their own unique values, preferences, and…

The use of program quality indicators (QIs) for teaching students with an intellectual disability (ID) is essential in meeting student needs and accessing curriculum. Principals who oversee and evaluate teachers of students with ID play a critical role in the implementation of QIs. A cross-sectional survey was conducted to investigate rural school…
