A randomized experiment that measures the impact of a social policy in a sample of the population reveals whether the policy will work on average with universal application. An experiment that includes only the subset of the population that volunteers for the intervention generates narrower "proof-of-concept" evidence of whether the…

Head Start is a national program that helps young children from families with low incomes get ready to succeed in school. It does this by working to promote their early learning and health and their families' well-being. The Head Start Family and Child Experiences Survey (FACES) provides national information about Head Start programs and…

The passing of the Education for All Handicapped Children Act---later renamed the Individuals With Disabilities Education Act---mandated that schools and districts ensure that all available education services were comparable between students with disabilities and general education students. This mandate led to students with disabilities and…

This study was designed to assess the impact of a decision-making curriculum (PEER-DM) on the social peer relationship knowledge and self-protective decision-making skills of adolescents with disabilities in hypothetical situations involving negative peer pressure. A randomized design was used to assign students with disabilities from…

Optimal levels of treatment fidelity, a critical moderator of intervention effectiveness, are often difficult to sustain in applied settings. It is unknown whether performance feedback, a widely researched method for increasing educators' treatment fidelity, is an evidence-based practice. The purpose of this review was to evaluate the current…

Students with disabilities experience poorer post-school outcomes compared with their peers without disabilities. Existing experimental literature on "what works" for improving these outcomes is rare; however, a rapidly growing body of research investigates correlational relationships between experiences in school and post-school…

We conducted a systematic review of the evidence related to online instruction in writing for students with special needs with the purpose of determining whether the existing literature can provide a research base and responding to special education researchers' concerns about students with disabilities receiving instruction online. We identified…

Problem solving is recognized as a skill, helping families of children with disabilities to manage problems in everyday life. Family problem-solving skills may therefore be seen as an important outcome of a child and youth habilitation service. The aim of this pilot feasibility study was to examine the design of a future web-based questionnaire…

The purpose of this review was to examine the methods used to conduct meta-analyses of single-subject research involving students with and at-risk for disabilities. Specifically, the procedures used for preparing, aggregating, analyzing, and evaluating single-subject data across 68 primary syntheses were examined. In addition to these…

Functional behavioral assessments can consist of indirect, descriptive and experimental procedures, such as a functional analysis. Although the research contains numerous examples demonstrating the effectiveness of functional analysis procedures, experimental conditions are often difficult to implement in classroom settings and analog conditions…

Previous research conducted by Nelson and Coorough (1994) found support for the statement that PhD programs were more research oriented, whereas doctorate of education (EdD) programs were more oriented to the educational practitioner. This previous study, however, had grouped all dissertations in education and had not looked at dissertations by…

Most models of mixed methods research design provide equal emphasis of qualitative and quantitative data analyses and interpretation. Other models stress one method more than the other. The present article is a discourse about the investigator's decision to employ a mixed method design to examine special education teachers' advocacy and…

The problem investigated in this research study relates to the referral rate for special education evaluations between students of teachers who were exposed to the professional development and resources associated with the federally funded Reading First program and students of teachers who were not exposed to the program. The purpose of this study…

In psychological and special education research, group comparison experimental designs are more often used than single subject experimental designs. However, the application of group designs poses many difficulties, such as the collection of large numbers of homogeneous subjects for a particular experimental condition, the averaging of individual…

Assessed effects of three-week break on elementary students with and without mild disabilities in mathematics. Found that regression was not indicated when levels of comparison were examined, although levels of performance for students with and without disabilities differed significantly after break. Students with positive prebreak trends were…
