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…

It is argued that outcome evaluation should include efforts to identify and measure unintended outcomes. A systems perspective is presented which treats governmental actions as disequilibrating intrusions into reacting systems. Both intended and unintended outcomes of such intrusions can be valued monetarily, in terms of human rights, or both.…

Professional evaluators are often called upon to analyze data produced by a catastrophically inadequate evaluation design. A remedial strategy involving diagnosis of error, application of a corrective procedure and sensitization of program personnel of the need for a more sophisticated stance, is proposed and illustrated with a case study.…

Studies examining the effectiveness of early intervention for infants and children with organic impairment and and developmental delay were reviewed using recently developed quantitative methods. Results suggest an accurate interpretation of the early intervention research literature cannot be made without consideration of specific design…

In reexamining the implementation results from a true experiment in criminal justice, this analysis brackets true treatment effects by partitioning experimental and control groups into treated and untreated subgroups and by combining two independent data sources. A positive association was found between magnitude of experimental treatment…

The authors respond to criticism and analyses by Eva Rezmovic (TM 507 851) of their experimental design, particularly the suggested use of information on the amount of program service received by the control group comparable to the treatment group in their study of the relationship between program implementation levels and program outcomes.

A three-dimensional framework presents faculty, student, and curriculum variables critical to the implementation and outcomes of multicultural programs. The framework emerged from the formative evaluation of a new interdisciplinary social science curriculum and guided the design of the national field test of that curriculum in community college…

This study of evaluation utilization identified organizational, political, and practical arrangements facilitating the wide use of "The Interim Report Evaluation" in policymaking for California's Early Childhood Education Program. In a program fraught by tensions, where evaluations had been political tools, this evaluation was special.…

The effects of the changing nature of intelligence test items during the follow-up period for compensatory education program evaluations on the judgments about program effectiveness are examined. Data from the Stanford-Binet and from three compensatory education evaluations, are examined. Methods for dealing with differential validity are…
