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…

The internationalization of distance learning in special education is at a pivotal point in expansion. Even with concerted efforts through traditional means to increase the supply of special educators, shortages persist; therefore, teacher preparation programs are turning to online education. This dissertation study was a formative program…

This article discusses the evaluation of programmatic interventions to enhance postsecondary STEM education for students with disabilities. SciTrain University, a federally funded project to provide instructor training on accessible teaching according to universal design principles, is presented here as a case study on evaluation for similar…

PCI Education conducted a three-year longitudinal study to determine the comparative effectiveness of the "PCI Reading Program" ("PCI") for students with severe disabilities as implemented in Florida's Brevard Public Schools and Miami-Dade County Public Schools. The primary question addressed by the study is whether students…

Studies designed to assess the efficacy of interventions with organically impaired infants in terms of how well the experimental designs used controlled for threats to interval validity were analyzed. The use of methodologically more rigorous designs in evaluation studies is recommended to prevent or ameliorate the adverse effects of…

PCI Education sought scientifically based evidence on the effectiveness of the "PCI Reading Program--Level One" for students with severe disabilities. During the 2007-2008 academic year. Empirical Education conducted a randomized control trial (RCT) in two Florida districts, Brevard and Miami-Dade County Public Schools. For this…

The monograph defines and discusses single subject research designs in special education. Advantages of this approach with measuring change in handicapped children are noted. Observational techniques (event recording, duration recording, interval recording, and time sampling) are described, along with three types of single subject evaluation…

The paper reviews the state of the art in evaluation research of direct instruction projects with handicapped students. The first section delineates research designs used (including norm referenced comparisons, nonequivalent comparison groups, and quasi experimental designs); major findings; and problems with each. A distinction is made between…

This article contrasts the traditional relationships between researchers and subjects in traditional rehabilitation evaluation and research with relationships between researchers and clients-consumers in new methodologies. Collaborative research, characterized by shared power and non-hierarchical authority between client-consumers and researchers…

Background: Many early intervention teams are shifting their service delivery for children with disabilities from a child-focused model to one that focuses on strengthening the competence and confidence of the child's caregivers (parents, childcare providers, preschool teachers). The use of coaching strategies in a primary coach model of service…

In 1991, the Office of Special Education and Rehabilitation Services (OSERS) authorized, under the Individuals with Disabilities Act (IDEA), a specific grants program. The State Systems for Transitions Services for Youth with Disabilities Program made available competitive 5-year grants to individual states for establishing responsive state…

Part of a volume which explores current issues in service delivery to infants and toddlers (ages birth to 3) with handicapping conditions, this chapter presents program evaluation as a comprehensive process comprising three phases: input, process, and output. Three program evaluation models are summarized: Tyler's objective model, Scriven's…

Describes a series of 16 longitudinal studies conducted by Utah State University on alternative early intervention programs for disabled children, focusing on the intensity of intervention, the age intervention begins, and parent involvement. Reviews factors that gave rise to the studies, research designs and procedures, and data interpretation.…

A 2-year pilot program in Toronto, Ontario, used in-school learning centers (LC) to enable 60 variously handicapped students in three junior schools to withdraw from self-contained classes and mainstream into regular classes. To develop the program, a Special Education Work Group performed such activities as writing issue papers, visiting 12…

This book is a guide to conducting follow-up studies on outcomes for students with disabilities and other special needs in school-to-work and other transitional programs. An accompanying computer disk contains a bank of survey items organized by the basic content areas found in most follow-up studies. Chapters offer a step-by-step guide through…
