With the push for evidence-informed policy and practice, schools and policy makers are now increasingly encouraged and supported to use and enagage with research evidence. This means that consumers of research will now need to be discerning in judging the quality of research evidence that will inform their decisions. This paper evaluates the…

Successful school reform is dependent on the quality of decisions made by educational leaders. In such decision making, educational leaders are charged with using sound research findings as the basis for choosing school reform initiatives. As part of the debate regarding the usability of various evaluative research designs in providing information…

This paper provides practical guidance for researchers who are designing and analyzing studies that randomize schools--which comprise three levels of clustering (students in classrooms in schools)--to measure intervention effects on student academic outcomes when information on the middle level (classrooms) is missing. This situation arises…

The purpose of this paper is to provide a basis for judging the adequacy of evaluation plans or, as they are commonly called, evaluation designs. The authors assume that using the procedures suggested in this paper to determine the adequacy of evaluation designs in advance of actually conducting evaluations will lead to better evaluation designs,…

The primary aim of the Middle School Intervention Project (MSIP) is to evaluate the impact of a multi-component intervention for struggling adolescent readers on reading outcomes. The intervention consists of: (1) targeted, Tier 2 reading and (2) school engagement interventions, and (3) data-based-decision-making (DBDM) teams to review and act on…

I define a treatment effect in terms of a comparison of outcomes and provide a typology of all possible comparisons that can be used to estimate treatment effects, including comparisons that are relatively unknown in both the literature and practice. I then assess the relative merit, worth, and value of all possible comparisons based on the…

A large body of literature documents the central importance of fidelity of program implementation in creating an internally valid research design and considering such fidelity in judgments of research quality. The What Works Clearinghouse (WWC) provides web-based summary ratings of educational innovations and is the only rating group that is…

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…

The last major review of the achievement outcomes of comprehensive school reform (CSR) models was conducted in 2003. Despite the growing evidence base supporting CSR, the program was discontinued by the federal government in 2007. Now, six years after the 2003 meta-analysis, the study's lead author, Geoffrey Borman, revisits the results and…

Scholars in the field of special education put forth a series of papers that proposed quality indicators for specific research designs that must be present for a study to be considered of high quality, as well as standards for evaluating a body of research to determine whether a practice is evidence-based. The purpose of this article was to pilot…

This article reports on the results of a study undertaken by the U.S. Department of Education on the impact of the Reading First program, which offer little insight into which parts of the program are worth saving and which need revamping. The study found that the $6 billion spent on the program has helped students with basic decoding but not with…

The gold standard in making causal inference on program effects is a randomized trial. Most randomization designs in education randomize classrooms or schools rather than individual students. Such "clustered randomization" designs have one principal drawback: They tend to have limited statistical power or precision. This study aims to…

This is a critical review of methodological issues in the evaluation of adult literacy education programs in the United States. It addresses the key research questions: What are the appropriate methods for evaluating these programs under given circumstances. It identifies 15 evaluation studies that are representative of a range of adult literacy…

Increasing demands for evidence-based early childhood services and the need by policymakers to know whether a program is effective or whether it warrants a significant investment of public and/or private funds--coupled with the often-politicized debate around these topics--make it imperative for policymakers and civic leaders to have independent…

In consultation with experts in the fields of education research and whole school improvement, researchers at the Comprehensive School Reform Quality (CSRQ) Center created a framework for evaluating the scientific rigor of research studies that report on the efficacy of whole school improvement models. In this paper, the authors begin with a brief…
