Over the past 15 years, we have seen an increase in the use of cluster randomized trials (CRTs) to test the efficacy of educational interventions. These studies are often designed with the goal of determining whether a program works, or answering the what works question. Recently, the goals of these studies expanded to include for whom and under…

The recent research on school or educational leadership is reviewed in an attempt to define some of the major recurring research problems. This paper outlines and describes both methodological problems and organizational perspective problems so that future research efforts can be strengthened. (BW)

This exploratory paper analyzes the federal policy for an impact study of research and development projects in vocational education. Positive effects were found on student outcomes, project personnel, and on occupational education practices. (Author)

A model is described which illustrates two general uses of multiple analyses to evaluate quasi-experiments: obtaining estimates of the treatment effect, and checking the validity of the experiment. (MH)

Several conceptions of schooling are outcome-bound: input-output models, school effectiveness models, classroom learning models, and systems theory models. Problems with each of these conceptions are identified, followed by a brief discussion of an outcome-free approach in which schools are viewed as cultural ecologies. (BW)

Research in the area of the instructional leadership of the school administrator is reviewed. Weaknesses in studies of instructional leadership are grouped as methodological, measurement, and conceptual problems. These problems define an agenda for improving research in the area of instructional leadership. (SLD)

K. S. Schiller, S. Plank, and B. Schneider argue that whether or not curricular differences exist between choice and nonchoice public schools cannot be answered by the analysis of Sosniak and Ethington. Sosniak and Ethington reiterate that choice as a policy is not a mechanism for stimulating curriculum change. (SLD)

The goal of this policy analysis is to set fair standards for awarding units of credit to disabled high school students. Criteria used for selection include: (1) equal protection under the Fourteenth Amendment; (2) education under the 1973 Vocational Rehabilition Act, Section 504; (3) feasibility; (4) flexibility; and (5) integrity of the high…

A detailed and critical analysis of the evaluation of the Follow Through program is presented. The history, critical decisions, and politics of the evaluation are examined. (JKS)

Evaluation research is no longer taught solely as a technical-scientific pursuit, but is now moving toward a policy-oriented discipline. Psychological skills in a political context can strengthen technical contributions of evaluators. (LMO)

The author advances the argument that evaluation is unique not in purpose, but in environment. The evaluator operates within ethical, organizational, and political contexts in order to achieve utilization of a context-responsive evaluation. (LMO)

Studies of the mathematics assessments of the National Assessment of Educational Progress (NAEP) are summarized. One study found that omit rates for NAEP test items were higher for African Americans and Hispanics than for whites. The other found that descriptions and examples for the 1992 mathematics achievement levels were misleading. (SLD)

Among the guidelines offered for educational policy-relevant research on the effects of school integration on minority student academic achievement are: age at which to desegregate students; school racial composition; ethnic or racial groups to be bused; instruction for non-Black minorities; and the role of social class.
