This article first outlines the logic of null hypothesis testing and the problems of using it to evaluate special education research. It then presents three alternative metrics, a binomial effect size display, a relative risk ratio, and an odds ratio, that can better identify important treatment effects using illustrative data from recently…

This paper presents nationally representative information about the extent of disproportionate gender representation in special education for the disability conditions of learning disabilities, mental retardation, and emotional disturbance. Recommendations are made for research to elucidate the basis for differences, improved data collection and…

Teacher self-reports of the frequency of currently advocated early literacy practices in Grades 1 through 3 were entered into regression models in an effort to predict 3rd-grade outcomes. Explicit skill instruction was a significant predictor of higher passing rates on a state examination and lower rates of special education referral but was also…

Discussion of the relationship between child maltreatment and child disability identifies three categories: (1) maltreatment causes many disabilities; (2) children with disabilities are more vulnerable to maltreatment; and (3) other primary causal factors increase risk for both violence and disability. Maltreatment is also seen as impeding student…

Discussion of the methods of meta-analysis first identifies problems associated with research integration, the limitations of traditional review techniques, and the advantages of quantitative methods. Meta-analytic procedures are described with respect to how they parallel classical scientific method, including problem formulation, sampling,…

Discussion of the need for systematic methods for summarizing single-participant research describes various approaches for quantitative synthesis and reviews conclusions of completed synthesis efforts. The issue of whether outcomes of single-participant research can be represented by a single common metric is addressed with the recommendation that…

Thirty-four adolescents with learning disabilities received either spelling strategy training, spelling strategy plus attribution training, or a control condition. Significant differences in spelling recall scores favored the strategy training condition. Addition of the attribution training resulted in no observable improvement in spelling…

Two studies focused on concurrent validity and instructional decision making in using alternative reading measures with elementary regular and special education students. The first study examined the relation of oral reading performance to several other reading measures; the second study investigated teacher decision making, using quantitative and…

The authors of a report on the technical adequacy of alternative reading measures reflect on issues concerning "whole language" terminology, the use of both quantitative and qualitative measures, and instructional decision making. (DB)

To illustrate the impact of research on the performance and quality of life of individuals with disabilities, this article highlights three research areas supported by the Individuals with Disabilities Education Act (IDEA): (1) at-risk infant programs; (2) learning strategy interventions for adolescents with learning disabilities; and (3)…

This study assessed the effectiveness of clique analysis methodologies in detecting changes in integration levels for a worker with severe mental retardation in a supported employment setting. The analysis suggested that communication instruction resulted in the worker becoming more integrated during break or lunch times. (Author/DB)

The researchers who conducted a study of the views of regular elementary teachers toward provision of special services through either "pull-in" or "pull-out" programs consider the researcher's role as change agent. The authors stress the timing of their research (with new legislation mandating consultant teacher services) and the importance of…

The researchers who conducted a review of 995 journal articles on mainstreaming reflect on the finding that there has been much more survey research than direct measurement of teacher and student performance. The need for empirical research on instruction and learning in inclusive settings is stressed. (DB)

Guidelines for the implementation of qualitative methods in special education research are offered, addressing rigor, sample selection, data collection, and data management/analysis. Five possible pitfalls are identified, including the quantitative-qualitative methods debate, premature data collection, the tendency to use a linear procedural…

The authors of EC 610 840 reflect on their use of data from the federally developed National Education Longitudinal Study for their research. They identify specific weaknesses of their study stemming from use of this database (such as lack of severity data) as well as strengths (use of a national sample). Researchers are urged to utilize such…
