The behavior of children from a wide range of family backgrounds was observed in elementary school classrooms several years after program services had been delivered. The results indicated that program participants benefited, particularly in the area of academic learning behavior. (Author/BW)

The impact of a 19-year-old leadership training program on participants was studied through qualitative and quantitative measures. Data from 234 participants show that they perceived that their knowledge and skills increased and that their attitudes changed as a result of the training workshop. Implications for organizational training programs are…

Compared standardized criterion-referenced achievement testing of undergraduate generalist social work knowledge (based on correct answers to specific questions) to several norm-referenced measures of student learning, including self-reports and instructor-imposed grades. Discusses weaknesses of each approach and implications for the assessment of…

Estimates of program effects from a compensatory preschool intervention were investigated using econometric simultaneous modeling, latent variable structured modeling, and ordinary least squares regression. Data for 806 black children indicated that different quasi-experimental estimation methods that attempt to control for selection bias can…

Statistical approaches to assess how prevention and intervention programs achieve their effects are described and illustrated through the evaluation of a health promotion program to reduce dietary cholesterol and a school-based drug prevention program. Analyses require the measurement of intervening or mediating variables to represent the…

DARE's effectiveness in Charleston County (South Carolina) was studied by comparing 341 DARE to 367 non-DARE fifth-grade students. DARE teaches students to recognize and resist social pressures to use drugs. DARE has positive impacts on anti-substance abuse attitudes, assertiveness, positive peer association, association with drug-using peers, and…

The relationship between level of program implementation and change in adolescent drug use behavior in the Midwestern Prevention Project was assessed. Results for 5,065 sixth and seventh graders at follow up are discussed in terms of research assumptions about the quality of program implementation and possible school-level predictors of…

To identify general principles of implementing a system of evaluation, the experience of Malawi in building a national system for agriculture is described. Applying principles of both centralization and decentralization and principles of trial and error has helped translate theories of evaluation into practice in Malawi. (SLD)

An outcomes-based model was developed to evaluate vocational education programs in Illinois. The model, which evaluates programs based on six vital signs of program quality, uses a series of computer technology expert systems to give local personnel assistance in exploring program problems and improvement. (SLD)

Difficulties experienced in implementing a randomized design in a school-based adolescent health promotion program are explained, and a solution using a randomized control group design nested within two treatment options is proposed. The Health for Life project involved 21 middle schools in Wisconsin. (SLD)

An evaluation of efforts by the Carter and Reagan Administrations to reduce fraud, error, and mismanagement in social programs is provided, examining the food stamp program as an example. Data available do not make it possible to say whether these administrative and political efforts actually decreased fraud and error. (SLD)

Three methods of estimating tobacco products experimentation were examined in 13 junior high and 6 high schools. The methods were aggregated students' self-reports of tobacco experimentation, school personnel prevalence estimates of student tobacco experimentation, and school outdoor refuse evidence. The school personnel method proved the most…

A pooled cross-section time series model is used to evaluate the effect of the 1977 Canadian firearms legislation on the provincial homicide rate between 1969 and 1989. Results agree with most studies that indicate no significant effect of this legislation on homicide rates. (SLD)

D. Freedman and others and W. Clark and P. Morrison misunderstand case law in the voting rights area and have unrealistic standards of precision that, if adopted, would make it virtually impossible for minority plaintiffs to succeed. Ecological regression, when used with care, is a reliable tool. (SLD)

The following methods of estimating school-level experimentation with drugs by adolescents at 20 California continuation high schools are compared: (1) self-reports; (2) prevalence estimates from students; (3) prevalence estimates from school staff; (4) naturalistic observation; and (5) refuse (garbage) analysis. Advantages of refuse analysis are…
