Available in PDF, EPUB and Kindle. Book excerpt: The What Works Clearinghouse (WWC) systematic review process is the basis of many of its products, enabling the WWC to use consistent, objective, and transparent standards and procedures in its reviews, while also ensuring comprehensive coverage of the relevant literature. The WWC systematic review process consists of five steps: (1) Developing the review protocol; (2) Identifying relevant literature; (3) Screening studies; (4) Reviewing studies; and (5) Reporting on findings. A separate "What Works Clearinghouse Standards Handbook" (ED577036) describes Step 4, including the standards used by the WWC to review studies and assign one of the following three study ratings indicating the credibility of evidence from the study: "Meets WWC Design Standards Without Reservations," "Meets WWC Design Standards With Reservations," or "Does Not Meet WWC Design Standards." Taken together, these two documents replace the single document used since March 2014, the "What Works Clearinghouse Procedures and Standards Handbook (Version 3.0)." Figure I.1 shows how the steps of the WWC systematic review process are divided between the two Handbooks. In general, this new "Procedures Handbook" contains the same procedures that were included in the "Procedures and Standards Handbook (Version 3.0)." However, in addition to changes to the organization, the following substantive updates were made: (1) The "Handbook" includes additional information that can be specified in review protocols. This additional information may be needed because of updates to the "WWC Standards Handbook" or to take into account methodological considerations that may vary by topic area; (2) The "Handbook" includes additional clarification of procedures. The additional clarification of the procedures is intended to support consistency across reviews, and includes new discussion of how the WWC defines studies and conducts its correction for multiple comparisons within studies; (3) The "Handbook" includes updated formulas for calculating statistical significance of findings. The formula for continuous outcomes includes a new small sample size adjustment, and a separate formula is provided for dichotomous outcomes; and (4) The "Handbook" includes procedures for reporting findings from randomized controlled trials that present complier average causal effects. A new appendix describes how the WWC reports findings and statistical significance from studies with complier average causal effect estimates to examine the effects of intervention participation rather than intervention assignment. The remainder of the document is organized as follows: Chapter II describes the steps that the WWC uses to develop a review protocol. Chapter III describes how the WWC identifies the relevant literature. Chapter IV describes the screening process to determine if a study is eligible for review, and Chapter V describes the procedures used to review eligible studies. Chapter VI describes how the WWC summarizes evidence of effectiveness. Organizational procedures used by the WWC to ensure an independent, systematic, and objective review are described in the appendices. As the WWC uses and applies the procedures in this "Procedures Handbook," reviewers may occasionally need additional guidance. If necessary, the WWC will produce guidance documents for reviewers to provide clarification and interpretation of procedures and support consistency across reviews. This WWC reviewer guidance will clarify how these procedures should be implemented in situations where the current "Procedures Handbook" is not sufficiently specific to ensure consistent reviews. As the WWC continues to refine and develop procedures, the "Procedures Handbook" will be revised to reflect these changes. [See ED544775 to review the previous version of this guide. ].

This book was released on 2014 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: This "What Works Clearinghouse Procedures and Standards Handbook (Version 3.0)" provides a detailed description of the standards and procedures of the What Works Clearinghouse (WWC). The remaining chapters of this Handbook are organized to take the reader through the basic steps that the WWC uses to develop a review protocol, identify the relevant literature, assess research quality, and summarize evidence of effectiveness. Organizational procedures used by the WWC to ensure an independent, systematic, and objective review are described in the appendices. Table I.1 provides a summary of the remaining chapters and associated appendices. The main differences between this version of the procedures and standards and the previous version (Version 2.1) are in clarity, detail, and scope. The organization of the Handbook, as well as all text, was reviewed and modified to support clarity; additionally, examples have been added throughout. There is more detail on the specific procedures and standards used by the WWC, including how to deal with missing data, random assignment probabilities, and cluster-level designs. Finally, whereas the previous version focused almost exclusively on intervention reports, this version provides information on other key WWC products, which include practice guides, single study reviews, and quick reviews. As the WWC continues to refine processes, develop new standards, and create new products, the "What Works Clearinghouse Procedures and Standards Handbook" will be revised to reflect these changes. Appended are: (1) Staffing, Reviewer Certification, and Quality Assurance; (2) Policies for Searching and Prioritizing Studies for Review; (3) The WWC Study Review Process; (4) Pilot Regression Discontinuity Design Standards; (5) Pilot Single-Case Design Standards; (6) Magnitude of Findings for Randomized Controlled Trials and Quasi-Experimental Designs; and (7) Statistical Significance for Randomized Controlled Trials and Quasi Experimental Designs.

This book was released on 2008 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook describes the structure and processes that the What Works Clearinghouse (WWC) uses for its reviews, presenting in one place all the standards the WWC currently uses to assess research. The handbook will be revised as new standards are developed and major new features are finalized. A distinguishing feature of the WWC is that it does not directly assess programs, policies, or practices, but reviews and reports on the findings from existing research that meets particular standards. The handbook details the components of the review process, including defining the topic area, identifying all potential research papers that fit the topic area, screening in the eligible papers, defining and prioritizing interventions within the topic area, reviewing the studies of the intervention, producing intervention reports, and proceeding through several rounds of quality assurance before finalizing reports. Review topic areas are identified through a collaborative process combining input from policymakers, researchers, and experts in the field. The topic areas are organized around key student outcomes, with special attention given to academic outcomes, though topic areas might also be organized around non-academic outcomes. Topic areas currently under review include Beginning Reading, Dropout Prevention, Early Childhood Education, Elementary School Math, English Language Learners, and Middle School Math. Seven appendices are included: (1) Assessing Attrition Areas; (2) Effect Size Computations; (3) Clustering Correction of the Statistical Significance of Effects Estimated with Mismatched Analysis; (4) Benjamini-Hochberg Correction of the Statistical Significance of Effects Estimated with Multiple Comparisons; (5) Intervention Rating Scheme; (6) Computation of the Improvement Index; and (7) Extent of Evidence Categorization. An index is included. (Contains 14 footnotes, 1 figure and 4 tables.).

Book excerpt: With its critical assessments of scientific evidence on the effectiveness of education programs, policies, and practices (referred to as "interventions"), and a range of products summarizing this evidence, the What Works Clearinghouse (WWC) is an important part of the Institute of Education Sciences' strategy to use rigorous and relevant research, evaluation and statistics to improve our nation's education system. The mission of the WWC is to be a central and trusted source of scientific evidence for what works in education. Without a service like the What Works Clearinghouse, it can be difficult, time-consuming, and costly for educators to access the relevant studies and reach sound conclusions about the effectiveness of particular interventions. Educators who want to know whether a particular intervention is effective can read a WWC Intervention Report and know that it represents both a thorough review of the identified research literature on that intervention and a critical assessment and summary of the evidence reported by the study authors. In this version of the Handbook, pilot standards for judging the conditions under which studies using regression discontinuity or single-case designs meet WWC standards for causal validity have been added. As the WWC continues to refine processes, develop new standards, and create new products, the Handbook will be revised or augmented to reflect these changes. Chapter I describes the roles of those who contribute to the topic area reviews, along with details on participating organizations and conflicts of interest. Chapter II provides guidelines for identifying topic areas, research and interventions to develop intervention reports. Chapter III explains the review process. Chapter IV describes the types of intervention reports, the process of preparing the report, components of the intervention report, the rating system used to determine the evidence rating, and the metrics and computations used to aggregate and present the evidence. Appended are: (1) Assessing Attrition Bias; (2) Effect Size Computations; (3) Clustering Correction of the Statistical Significance of Effects Estimated with Mismatched Analyses; (4) Benjamini-Hochberg Correction of the Statistical Significance of Effects Estimated with Multiple Comparisons; (5) Pilot Standards for Regression Discontinuity Designs; (6) Pilot Standards for Single-Case Designs; (7) Intervention Rating Scheme; (8) Computation of the Improvement Index; and (9) Extent of Evidence Categorization.
