This document provides guidance about how to describe studies and report their findings in a way that is clear, complete, and transparent. This document does not include information about how studies are judged against What Works Clearinghouse evidence standards. For information about What Works Clearinghouse evidence standards, please refer to…

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…

Progress in International Reading Literacy Study (PIRLS) provides international comparative data about students' reading achievement after four years of primary schooling, while also measuring trends over time, monitoring curricular implementation, and identifying promising instructional practices. Conducted on a regular 5-year cycle, PIRLS has…

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…

Six statistical methods for identifying possible sources of bias in standardized test items are presented. The relationship between chi-squared methods and item-response theory methods are also discussed. (Author/BW)

Seven methods for measuring and comparing value added in higher education are considered; six are index methods (all found unsatisfactory for lack of empirical support) and a seventh is proposed which calculates value added as the difference between the outcomes achieved and those predicted from national (United Kingdom) data. The advantages of a…

Different kinds of financial data are needed by different levels of management and in different areas of support. Accounting principles for nonprofit organizations need to be determined. Accrual accounting principles, fund accounting, restricted and unrestricted funds, etc., are described. (MLW)

Presents three different, complementary statistical models for predicting faculty tenure dynamics, using data from Worcester Polytechnic Institute (Massachusetts). The difference equation model exactly describes future behavior but requires complete specification. The Markov-chain model can predict the full life-cycle of tenure from initial age…

Two procedures for systematic organizational quality assessment are presented: (1) a distributional assessment to monitor individual, group, or unit performance by establishing real and maximum-feasibility parameters; and (2) a cost-assessment system based on utility analysis, to assign dollar values and benefits to quality interventions targeting…

Several methods of assessing test item bias are described, and the concept of fair use of tests is examined. A test item is biased if individuals of equal ability have different probabilities of attaining the item correct. The following seven general procedures used to examine test items for bias are summarized and discussed: (1) analysis of…

This paper comments on the impact of computers on statistical analysis and presents a concise, nontechnical overview of five statistical methods now being applied in educational research. Appropriate uses of these techniques are pointed out, along with dangers concerning misapplications. (PP)

Financial indicators to describe and measure the condition of colleges and universities are discussed including: determining capital charges against current revenues, analyzing revenue structures, dissecting the expenditure structure, and restating current fund revenues and expenditures. (MLW)

Reports on a study which collated and compared evaluations of seven distance education courses in Hong Kong using a combination of quantitative and qualitative methods. Conclusions about tutorials, group activities, interstudent contact, telephone counseling, and video and television broadcasts are synthesized; and guidelines for formatting…

Discusses how to examine and evaluate claims of improved academic performance in advertisements for computer-assisted instruction. Highlights include the proper use of comparison groups; types of statistical analyses; the Hawthorne effect; the interpretation of scores; interpreting graphic presentations; tests of significance; and cost…

Designed for language teachers who find reading statistical research difficult but necessary, this article focuses on the minimal knowledge needed about statistical techniques for interpreting research findings. It first examines the statistical reasoning underlying quantitative, empirical studies, including normal distribution, standard…
