Flexibility in evaluative research design does not necessitate the abandonment of randomly constructed comparison groups. Three designs are reviewed which provide at least the option of randomization while maintaining great flexibility. The strengths and weaknesses of the designs are discussed. (Author)

The "CSE Program Evaluation Kit" is a series of nine books intended to assist people conducting program evaluations. This volume, the third in the kit, discusses the logic underlying the use of quantitative research designs, including the pretest-posttest design, and supplies step-by-step procedures for setting up and interpreting the…

Practical methods for implementing true experimental designs in evaluation settings in which such designs are rarely used are presented. Particular attention is paid to educational settings. (Author/JKS)

A study was made of a noncredit home economics program presented by the University of Wisconsin Extension over the statewide Educational Telephone Network (ETN). The study was limited to the total population involved in one program (54) and their immediate reaction to that program. Methodology used was a combination of action research and field…

This study estimated a component of within-school variance which has been overlooked in policy research studies and program evaluations performed to date: the effect on pupil performance of different teachers within a single school or program. Results indicated that teacher effects accounted for 30 to 40 percent of within-school variance. (Author/…

The evaluation design, which prescribes when and from whom to gather data, is described as significant because it can lend credibility to evaluation results. The objectives of this booklet are to aid the evaluator in: choosing a design; putting it into operation; and analyzing and reporting the data. Examples include both formative and summative…

A review of the literature suggests that choice of control group may have affected the policy implications of the major evaluations of governmental training programs. It is argued that the usual evaluation designs underadjust for preprogram differences between trainees and the control group and thus yield biased estimates of program impact.…

In summer of 1970, the Atlanta Public Schools received funds for a camp project involving 380 junior high pupils, 95% Negroes and 5% Caucasians. Objectives included providing the opportunity for pupils to assume responsibility, develop self-reliance, and thereby increase self-respect; teaching the skills involved in outdoor recreation; teaching…

The utility of the biomedical model of adjusted statistics is demonstrated. The model is recommended for use by educational researchers to randomize subjects for a more accurate estimate of school programs' success or failure when compared across classrooms or other units. (Author/MH)
