In 2010, the Institute of Education Sciences commissioned a much-needed national evaluation of response to intervention (RTI). The evaluators defined their task very narrowly, asking "Does the use of universal screening, including a cut-point for designating students for more intensive Tier 2 and Tier 3 interventions, increase children's…

The report of the national response to intervention (RTI) evaluation study, conducted during 2011-2012, was released in November 2015. Anyone who has read the lengthy report can attest to its complexity and the design used in the study. Both these factors can influence the interpretation of the results from this evaluation. In this commentary, we…

Treatment fidelity, or the application of an intervention as it is designed, is a critical issue for the successful implementation of evidence-based practices. Typically it is assumed that evidence-based practices implemented with high fidelity will result in improved outcomes, whereas low fidelity will lead to poorer outcomes. These assumptions…

Evidence-based programs will be useful to the extent they produce benefits to individuals on a socially significant scale. It appears the combination of effective programs and effective implementation methods is required to assure consistent uses of programs and reliable benefits to children and families. To date, focus has been placed primarily…

This study evaluated the impact of a curriculum called the Early Literacy Skills Builder on the language and early literacy skills of students with significant developmental disabilities. Students in the control group received the ongoing sight word and picture instruction prescribed by their individualized education programs. Results indicate…

This article reports on 2 studies investigating a response-to-intervention (RTI) approach to behavior support in 2 second-grade classrooms. The results suggest that a slightly more intensive but efficient targeted intervention ("check in and check out") was effective in supporting the social behavior success of 4 students whose problem behaviors…

The Proportional Change Index (PCI), a numerical statement of the relationship between children's rate of development during intervention with the rate of development at the time intervention began, is proposed as a way of expressing child progress from developmental data. (Author/CL)

This meta-analysis examines the effectiveness of functional mathematics instruction, specifically purchasing skill instruction, for individuals with disabilities. Twenty-eight intervention studies were identified and reviewed. Because all studies employed single-subject research designs, a nonparametric procedure, the percentage of nonoverlapping…

The Minority Issues Inservice Program, a three-year cooperative inservice program regarding special education of minority handicapped children, was evaluated with 34 participants (building trainers, teacher trainees, contrast Ss). Results indicated that trainees increased their weekly mastery, made substantial and continuing applications, and had…

Two highly contrasting models of preschool education for mildly handicapped children were compared. Direct Instruction led to greater gains on the Test of Early Language Development and the Basic Language Concepts test. Mediated Learning led to greater gains on the McCarthy Verbal and Memory scales and Mean Length of Utterance measure. (Author/VW)

The United States Department of Education's tenth annual report on the implementation of Public Law 94-142 contains improvements but shows overdependence on reporting numbers of students without descriptions of evolutions in service delivery, and raises questions about the effectiveness of monitoring efforts carried out by the Office of Special…

The review of the literature describes services available or recommended for students with learning disabilities at community colleges and traditional four-year colleges. Although a wide variety of services are now available, there is little empirical evidence on the effectiveness of those services. (Author/DB)

A systematic parent training program was developed within the Portage Project Model, which provides weekly visits by home teachers to families with a preschool handicapped child. (SBH)

The Teaching Research Transition Planning Project (Oregon) is implementing and evaluating the development of school/community teams to facilitate transition of handicapped students into the community. Preliminary evaluation results support the value of an outside stimulus to encourage collaboration, locally generated plans, and policy decision…

This study assessed the impact of training on the knowledge and confidence of over 80 teachers in decision making regarding participation and accommodation for students with disabilities in large-scale assessments. After training teachers expressed high confidence in their ability to make such decisions and a stronger relationship was found among…
