There are unique challenges to estimating causal effects of preschool for students with special needs that have not received attention in the literature. We revisit the Head Start Impact Study (HSIS) to illustrate that when and how special needs is defined has implications for the internal validity of and interpretation of special needs subgroup…

This article examines the power analyses for the first wave of group-randomized trials funded by the Institute of Education Sciences. Specifically, it assesses the precision and technical accuracy of the studies. The authors identified the appropriate experimental design and estimated the minimum detectable standardized effect size (MDES) for each…

To illustrate the point that incremental policy changes are important results of program evaluation, the author investigated the influence of evaluation on federal education policymaking as seen in the 1978 reauthorization of the Bilingual Education Act. (LC)

The Experience Based Career Education (EDCE) program serves as a focal point of a cast study documenting how the National Institute of Education secured Office of Education funds to demonstrate an R&D innovation. Serious questions are raised about the regulations-writing process and the use of evaluation information. (Author/LC)

Five activities are proposed for a federal evaluation agenda for the 1980s: (1) measuring net impact of social program cost containment; (2) implementing and evaluating new social experiments; (3) examining appropriateness of current social programs; (4) testing alternatives to established programs; and (5) developing procedures to ensure…

Conducted a cost-benefit analysis of a federally financed comprehensive early childhood program, the Title I Chicago Child-Parent Centers. Used data for 1,539 program and comparison group children. Findings show that an established public program can provide benefits that far exceed costs. Outlines key elements of program effectiveness. (SLD)

This paper shows how several of Cook and Gruder's meta-evaluation models have been applied in the national evaluation of Project Follow Through. Participants in the evaluation are identified, their roles are described, and the degree to which these roles map onto the meta-evaluation models is assessed. (Author/BW)

Meta-analytic techniques were used to study the overall impact of the Title I program on student achievement and to examine the effects of mediating methodological and programmatic factors. Data from 17 Federal studies with 657 effect sizes indicate a modest impact of Title I that increased as the program matured. (SLD)

This paper focuses on the National Sex Equity Demonstration Project, a joint effort of the University of Miami and the Broward County School Board funded by the Women's Educational Equity Act Program. The author concludes that the project made a modest, but important, contribution to the definition of educational equity. (Author/DWH)

Citing the signaling and charged use distinction, examines federal expectations and need for evaluation data and extent of local capabilities to meet those expectations when secondary/transition model demonstration projects, funded by the Office of Special Education and Rehabilitation Services, were obligated to improve amount, quality, and use of…

Case studies describe the changes occurring in a large urban school system following passage of the Hawkins Stafford Amendments allowing the use of Chapter 1 funding in schoolwide projects (SWPs) in schools where 75 percent or more of students are economically disadvantaged. The potential of SWPs is discussed. (SLD)

The schoolwide project option of the 1988 Hawkins Stafford Amendments to Chapter 1 allowed a rural school serving a disadvantaged Native American population to restructure its compensatory and regular education services. Santo Domingo school (New Mexico) illustrates the ways modifications of federal law and policy benefit children. (SLD)

This paper reviews early research at the national level on the implementation and effects of the Department of Education's block grant, Chapter 2 of the Education Consolidation and Improvement Act of 1981. Findings are summarized under six topics: funds allocation, educational service delivery, program administration, program assessment, decision…

Implementation of schoolwide projects in Philadelphia (Pennsylvania) illustrates some of the conceptual problems associated with the Hawkins Stafford accountability amendments to the Chapter 1 supplementary education program. Unintended negative consequences are discussed, and recommendations are made to overcome these problems, including the…
