The existing outcome literature on the use of oral-only and total communication approaches for young deaf children is reviewed and methodological and practical difficulties of outcome research explored. The authors propose a developmental/transactional, clinically based process model for evaluating the effectiveness of early intervention.…

This paper discusses the results of a study that investigated the progress of 51 children receiving long-term dynamically-oriented therapy at a naturalistic "real world" clinic. The orientation of the Outpatient Clinic of the Yale Child Study Center is primarily long-term, psychodynamic treatment. Parents and clinicians completed…

Strasser and Deniston's own analysis (TM 504 254) shows that post-planned evaluations are unsuitable substitutes for pre-planned evaluations. When viewed as post-experimental interviews, however, post-planned evaluations can produce valuable information which complements traditional experimental and quasi-experimental evaluations. (MH)

Meta-analysis of 143 effect sizes in 43 studies of adventure programming for adolescents found an overall effect size of 0.31. Summary effect sizes of outcome categories differed significantly among categories, however. Effect size was related to program length and participant age but not to delinquent status. Discusses the lack of pertinent…

A review of 913 studies involving students with learning disabilities found treatment outcomes were significantly affected by the following violations: teacher effects, establishing criterion levels of instructional performance, reliance on experimental measures, using different pretest and posttest measures, using a sample heterogeneous in age,…

This paper focuses on transition programs for youth to postsecondary education, broadly considered. It addresses the following questions: (1) What models or programs of transition exist? (2) On what basis can we say one transition program is more effective than another? In other words, how is successful transition defined? (3) How are…

A new report published by the Manhattan Institute for Education Policy, "The Effect of Special Education Vouchers on Public School Achievement: Evidence from Florida's McKay Scholarship Program," attempts to examine the complex issue of how competition introduced through school vouchers affects student outcomes in public schools. The…

Perhaps no facet of long-term care (LTC) research has received as much attention as the evaluation of community-based LTC demonstrations. Recent thinking has called into question the validity and policy relevance of the findings of these studies, yet their efforts will continue to receive strong financial backing. The time has come for LTC…

Self-selection bias poses a major threat to the validity of research findings in naturalistic, quasi-experimental, or single-group designs. A new method of addressing self-selection bias in naturalistic evaluations of prevention programs was implemented. The study, involving voluntary exposure to multicomponent interventions, was developed and…

Three British studies recently compared the examination results of pupils from comprehensive schools with those of selective schools. Each study reached somewhat contrasting conclusions. Major differences among the studies are discussed in order to clarify reasons for the contrasting interpretations and to illustrate the major difficulties in…

At the request of a Senate subcommittee, this report describes the value of conducting impact evaluations, describes their current use in evaluating selected early childhood education and care programs, and discusses the value of other types of early childhood education and care studies currently promoted and sponsored by the Departments of Health…

Evaluations of creativity training programs are described: (1) Productive Thinking; (2) Purdue Creative Thinking; (3) Parnes; (4) Myers-Torrance workbooks; and (5) Khatena. Conceptual and methodological problems are discussed. Although gains on tests of divergent thinking have been noted, it is unclear whether these programs improve real-life…

Reviews problems with research in determining the effectiveness of distance education, and presents a systems model to be used as a framework upon which researchers can build. The telecommunications in instruction model incorporates learner variables, instructor variables, presentational elements, course content elements, and distance education…

This paper cites modest beneficial effects of early intervention for children with developmental disabilities or children at risk, and examines two specific program features, age of start and family involvement. The moderating influence of the level of disability severity is also analyzed, and future directions for improving early intervention…
