It is a much-lamented fact that research with the potential to inform or influence education policy instead remains policy inert. There are many reasons for this frustrating state of affairs, including a lack of strategic thinking on the part of researchers on how to successfully accomplish outreach--as opposed to communication with peers…

This article promotes the use of modern test theory in testing situations where sum scores for binary responses are now used. It directly compares the efficiencies and biases of classical and modern test analyses and finds an improvement in the root mean squared error of ability estimates of about 5% for two designed multiple-choice tests and…

Learning standards across the United States have increasingly called for history students to engage in aspects of "historical thinking," a term used to describe the complex disciplinary processes that historians use to make sense of the past. Although students are expected to learn these complex processes, little is known about how to…

This article presents the author's observations on Neil Dorans's NCME Career Award Address: "The Contestant Perspective on Taking Tests: Emanations from the Statue within." He calls attention to some points that Dr. Dorans made in his address, and offers his thoughts in response.

In large-scale assessments, such as the National Assessment of Educational Progress (NAEP), plausible values based on Multiple Imputations (MI) have been used to estimate population characteristics for latent constructs under complex sample designs. Mislevy (1991) derived a closed-form analytic solution for a fixed-effect model in creating…

In information-rich environments, schools are often presented with a myriad of data from which decisions need to be made. The use of the information on a classroom level may be facilitated if performance could be described in terms of levels of proficiency or benchmarks. The aim of this article is to explore benchmarks using data from a monitoring…

The purpose of this investigation was to develop a general framework for qualitatively analyzing the 1992 National Assessment of Educational Progress (NAEP) extended constructed-response questions. The framework dimensions were based on information about the NAEP extended questions and linked to important ideas in mathematics education and…

Large-scale educational assessments differ from familiar educational measurements by attempting to provide information about the levels and natures of skills in populations rather than in individuals. That the distinct purposes of assessment require different methodologies than individual measurement was recognized by the development of…

In this paper, scores from the Department of Education's table, "State Education Statistics," are examined to see if they can be used for state-by-state comparisons to aid in the evaluation of educational policies that vary across states. (Author/LMO)

This paper extends the theory of conditional covariances to polytomous items. It has been mathematically proven that under some mild conditions, commonly assumed in the analysis of response data, the conditional covariance of two items, dichotomously or polytomously scored, is positive if the two items are dimensionally homogeneous and negative…

Four researchers at the Educational Testing Service describe what they consider some of the most vexing research problems they face. While these problems are not completely statistical, they all have major statistical components. Following the introduction (section 1), in section 2, "Problems with the Simultaneous Estimation of Many True…
