Inclusive education remains a significant challenge in today's educational landscape, as K-12 classrooms and higher education institutions struggle to meet the diverse needs of all students. To address this pressing issue, "Developing Inclusive Environments in Education: Global Practices and Curricula," led by Kiyoji Koreeda, offers…

In the past decade, American and Canadian pediatric societies have recommended that pediatric care clinicians follow a schedule of routine surveillance and screening for young children to detect conditions such as developmental delay, speech and language delays and disorders, and autism spectrum disorder. The goal of these recommendations is to…

The trusted core disability textbook gets a comprehensive update in this second edition, now thoroughly revised to include all the critical topics today's professionals need to know about as they work with people who have intellectual and developmental disabilities. Brought to you by a new team of world-renowned experts and contributors, this…

Research-informed policy and practice is needed for older caregivers of adult sons/daughters with disabilities. These caregivers are often under tremendous stress because of failing health, financial pressures, bereavement and worry about the future of their sons/daughters. Twenty-nine older parents/caregivers of 27 adults with intellectual and/or…

Although mothers of children with intellectual and developmental disabilities (IDD) experience high levels of stress and schools constitute an important resource, the relation remains unknown between maternal stress and educational services. Responding to a national, web-based survey, 965 mothers of students with disabilities completed a 163-item…

Families are critical in the provision of lifelong support to individuals with intellectual and developmental disabilities (IDD). Today, more people with IDD receive long-term services and supports while living with their families. Thus, it is important that researchers, practitioners, and policy makers understand how to best support families who…

Special education is now an established part of public education in the United States--by law and by custom. However, it is still widely misunderstood and continues to be dogged by controversies related to such things as categorization, grouping, assessment, placement, funding, instruction, and a variety of legal issues. The purpose of this…

This paper includes a nontechnical description of methods for calculating effect sizes in intellectual and developmental disability studies. Different hypothetical studies are used to illustrate how null hypothesis significance testing (NHST) and effect size findings can result in quite different outcomes and therefore conflicting results. Whereas…

We reviewed twelve studies that used the constant time delay (CTD) procedure to teach chained tasks to individuals with developmental disabilities from years 1996-2006. Variables analyzed include types of tasks that have been taught with the procedure, how effective CTD has been in teaching participants, and whether researchers have investigated…

This article criticizes the term "comorbidity" used to describe the overlap of developmental syndromes or disorders. Data from 179 school-age children are evaluated for criteria of seven disorders. Since fully 50 percent of the sample met the criteria for at least two diagnoses, the premise that these disorders are discrete categories on…

This paper examines the validity of Asperger syndrome as a condition apart from high-functioning autism. Potential differences between Asperger syndrome and autism is possible if both are strictly defined. The importance of genetic factors in Asperger syndrome is stressed. Research on the nosological validity of this condition and its relationship…

Quantitative behaviour analysis requires the classification of behaviour to produce the basic data. This can be challenging when the theoretical taxonomy does not match observational limitations, or if a theoretical taxonomy is unavailable. Binary keys allow qualitative observation to be used to modify a theoretical taxonomy to produce a practical…

Reviews the literature in two areas of research concerned with social development of siblings. Compares and contrasts studies of sibling relationships of handicapped children with the wider literature on nonhandicapped siblings. Focus is on methodological and conceptual features. (RWB)

This compilation presents five papers on issues and research in special education. "Qualitative Research in Special Education: An Evaluative Review" (Charles A. Peck and Gail C. Furman) explicates some of the epistemological assumptions underlying qualitative research methods, reviews examples of qualitative research, evaluates the contributions…

This paper proposes "severe developmental disabilities" (SDD) as a useful umbrella term for various severe handicapping conditions such as autism, severe mental retardation, and multiple handicaps. Diagnostic criteria for SDD include language deficiency, disturbed interpersonal relationships, inconsistent response to sensory stimulation,…
