An effect size of about 0.70 (or 0.40-0.70) is often claimed for the efficacy of formative assessment, but is not supported by the existing research base. More than 300 studies that appeared to address the efficacy of formative assessment in grades K-12 were reviewed. Many of the studies had severely flawed research designs yielding…

The new "Weighted Student Formula Yearbook 2009" from the Reason Foundation provides a simple framework for touting the successes of states and urban school districts that grant greater fiscal autonomy to schools. The report defines the Weighted Student Formula (WSF) reform extremely broadly, presenting a variety of reforms under the WSF umbrella.…

Treatment integrity (also referred to as "treatment fidelity," "intervention integrity," and "procedural reliability") is an important methodological concerning both research and practice because treatment integrity data are essential to making valid conclusions regarding treatment outcomes. Despite its relationship to validity, treatment…

This special series focused on treatment integrity in the child mental health and education field is timely. The articles do a laudable job of reviewing (a) the current status of treatment integrity research and measurement, (b) existing conceptual models of treatment integrity, and (c) the limitations of prior research. Overall, this thoughtful…

The Center for Research on Education Outcomes (CREDO) at Stanford University conducted a large-scale analysis of the impact of charter schools on student performance. The center's data covered 65-70% of the nation's charter schools. Although results varied by state, 17% of the charter school students have significantly higher math results than …

"How New York City's Charter Schools Affect Achievement" estimates the effects on student achievement of attending a New York City charter school rather than a traditional public school and investigates the characteristics of charter schools associated with the most positive effects on achievement. Because the report relies on an…

The estimation of the "size of effect" of educational programs is a difficult problem in program evaluation. It is argued that the intentions of the program and the nature of the measures must be known in order to estimate program effects. (JKS)

Documenting treatment integrity is an important issue in research and practice in any discipline concerned with prevention and intervention. However, consensus concerning the dimensions of treatment integrity and how they should be measured has yet to emerge. Advances from three areas in which significant treatment integrity work has taken…

The concept of treatment integrity cuts across a diversity of fields involved with providing treatments or interventions to individuals. In medical treatments, the concept of "treatment compliance" or "treatment adherence" is an important and problematic issue. In the field of nutrition, the concept of "dietary adherence" is important for…

Three British studies recently compared the examination results of pupils from comprehensive schools with those of selective schools. Each study reached somewhat contrasting conclusions. Major differences among the studies are discussed in order to clarify reasons for the contrasting interpretations and to illustrate the major difficulties in…

Effective schools research problems (unreliable descriptions and definitions, over-dependency on tests, research limited primarily to elementary schools) result in narrow formulas leading to increased standardization, neglect of nonacademic areas, and failure to improve in schools with high test scores. Author urges using broader, more complex…

The methodology and findings of the Law-Related Education Project's research reports which evaluated the effects on secondary students of law-related education (LRE), are discussed. A response to James P. Shaver's negative critique of the Law-Related Education Project's research studies also is provided. A detailed account of the research results…

This paper presents a discussion of issues raised in the evaluation of Project Follow Through reported by Abt Associates. The paper suggests that many of the problems inherent in the design of both the program and the evaluation stem from the underlying assumption that one educational model could be found which would best alleviate the educational…

A program is described for the evaluation of the basic skills policy of the State Board of Education in Massachusetts. The 1978 policy of the Board is to take effect in 1980-81 and will require annual assessment of student skills at three grade levels in all schools in five curriculum areas, but leaves the setting of standards to local option.…

A centralized evaluation unit within the California State Department of Education is responsible for evaluating programs administered by the state. Focusing on these educational program evaluations, the principal objectives of this study were to: (1) Describe the major components of the current program evaluation system; (2) Examine the planning…
