The purpose of this paper is to summarize the research on service learning pedagogy into the realm of professional practice for students with disabilities. At this point in the development of a research base for service learning, an emerging need for studies is reported. Limited research exists which studies the impact of service learning…

A quantitative method, meta-analysis, is used to integrate research findings from a representative group of 38 coaching studies. Because different studies reported results on different scales, effect size was used to transform all results to a common metric. This meta-analysis showed that there are two distinct literatures on the effectiveness of…

A meta-analysis including nine samples of mothers in home visiting programs (N=1,600) examined differences in the effects of home visitor programs on maternal behavior. Although effect sizes varied, programs with more frequent visitation had higher success rates. This dosage effect explained all of the variance in effect sizes. Other significant…

This study explored the potential of meta-analysis for assessing the efficacy of interventions designed for parents of young, environmentally at-risk children. Included in the sample were 232 evaluations of 282 parent-focused interventions implemented between 1965 and 1999; evaluations met 10 criteria, including the inclusion of a treatment and…

This paper compares and summarizes empirical research on the outcomes of outdoor education (OE) and related programs. Most frequently, OE outcomes have been researched using post-program surveys of staff and participant attitudes. Such reports are vulnerable to many potential distortions. A second major approach to examining OE effectiveness…

In 1981 a meta-analysis of research in science education was completed by a team of researchers under the direction of Ronald Anderson at the University of Colorado. Individual teams synthesized the extant research using meta-analysis procedures. One of the syntheses showed that the post-Sputnik or "new" science programs on the whole…

Meta-analysis of 17 studies was conducted to determine the effectiveness of retaining elementary school students in grade. Calculations with data from the 17 studies produced 217 effect size measures, most of which were measures of differences in reading and mathematics achievement. Some measures of differences in social adjustment, behavior, and…

Because research synthesis enables one to determine either the overall effectiveness of a particular treatment or the relative effectiveness of different types of treatments, it is becoming increasingly popular as a tool in program evaluation. Numerous methodological problems arise, however, when research synthesis is applied to studies conducted…

A report is given of a statistical analysis of the summary findings of 14 empirical studies on the effectiveness of human relations training programs for teachers. The study sought to determine the direction and size of the effect produced by training, and determine which programs were most effective. Program approaches included: (1) Social…

The 1988 Hawkins-Stafford Elementary and Secondary School Improvement Amendments to Chapter 1 (now Title I) have enabled broad expansion of Title I schoolwide projects. The regulatory changes provide funding to entire schools, rather than targeting services to meet the needs of the most disadvantaged subpopulations. This paper reviews what is…

A meta-analysis of home visiting programs (K = 12, N = 2869) examined differences in the effects of home visitor programs for at-risk families on maternal behavior. Studies selected included only peer-reviewed publications and evaluations with a control group design. Although effect sizes varied, programs with more frequent visitation had higher…

A meta-analysis (37 published studies) that summarized treatment outcomes associated with skills training with antisocial youth was performed. As is consistent with the hypothesis, results indicate that skills training interventions delivered in the context of homogeneous groups of deviant peers produced smaller benefits than did skills training…

Preliminary findings of an analysis of Head Start research evidence amassed from 1965 to the present are reported in this document, along with a summary of conclusions from related studies of preschool programs. Specifically presented are long-term findings of the Consortium for Longitudinal Studies concerning the lasting benefits of preschool…

In order to increase statistical power, this study combined the data of three previous studies on the role of parent involvement in early intervention for children with disabilities. Each of the studies found a mixed pattern of positive results on child outcomes and, in two of the studies, on family outcomes. The combined subjects (n=181) had mild…

Educational programs and evaluations which were submitted to the Department of Education's Joint Dissemination Review Panel (JDRP), in order to be named validated programs, were studied to identify program characteristics associated with large versus small effect size. Effect size was calculated for 165 out of 232 submittals reviewed by JDRP from…
