The assumption of equal treatment implementation is questioned. Through the reanalysis of data from a nutrition supplementation program evaluation, the power of the analysis of treatment effects is shown to increase when data on the level of treatment implementation is included. (Author/CM)

Identifies the purpose and need for a vocational evaluation process in the correctional setting. Discusses the five steps in such a process: preliminary intake procedure, primary data gathering, hypothesis formulation phase, hypothesis testing phase, and outcome and/or follow-up. CCT)

Causes of evaluator bias are: overemphasizing concrete, salient, and retrievable information; reporting only evidence which confirms hypothesis; focusing on stable personality factors, rather than on situation and environment; developing positive perceptions of a program as both an evaluator and a highly involved participant; statistical naivete;…

Definitions of and approaches to naturalistic evaluation are discussed. The qualitative aspects of the discipline are reviewed; and use of naturalistic evaluation in descriptions, illustrations, explications, hypothesis testing, and assessment of public spending are defined. A new paradigm for naturalistic evaluation is proposed. (TJH)

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.

In spite of many inherent problems, impact evaluation should remain an integral part of program evaluation, both because impact evaluation brings its budget justification with it, and because its focus on causal hypotheses is an essential part of evaluation. Methodology based on the author's body of work is reviewed. (SLD)

Kentucky's PACE program, which was designed to provide adult basic education and parenting skills training for parents, early childhood education for children, and parent-child interaction and learning, lacks proof for the validity of its theoretical base and service model. Questions that need to be resolved before widespread replication of the…

Analyzes how Canadian immersion education has developed from its origins to the present in terms of a cycle guided by the interplay between theory and classroom practice of second- language acquisition. Johnson responds by questioning the extent to which bilingual education theory and practices are universal or context specific. (38 references)…
