Researchers have become increasingly interested in programs' main and interaction effects of two variables (A and B, e.g., two treatment variables or one treatment variable and one moderator) on outcomes. A challenge for estimating main and interaction effects is to eliminate selection bias across A-by-B groups. I introduce Rubin's causal model to…

Three different approaches to metaevaluation are described and shown to have been applied to the study of Project Follow Through. These approaches include evaluation of primary evaluations, integrative meta-analysis in which results from several primary evaluations are combined, and secondary analysis involving the independent reanalysis of the…

The first study, Black Pulse, whose purpose was to assess the conditions and attitudes of black Americans, consisted of a detailed, statistical survey of…

The movement toward integration of qualitative and quantitative research methods within the same study has been most evident in social policy research. Four major approaches to integrating can be identified in recent studies. The sequential, the parallel, and the fused models have been rather widely used. The interactive model, developed during…

Following up on the first two phases (1976-82) of the "District Practices Study" of Title I of the Elementary and Secondary Education Act (ESEA) as presented in a resource book and seven special reports, this report is devoted to the study's third and final phase. During phase III (1982-83), researchers visited 14 sites to describe their…

The National Longitudinal Evaluation of Comprehensive School Reform (NLECSR) is a quantitative and qualitative study of behavior, decisions, processes, and outcomes. It employs a quasi-experimental design with matched treatment and comparison schools. NLECSR seeks to determine the effects of CSR models on student achievement in about 650…
