This methodological study examines an original data collection model designed to incorporate human factors and enhance data richness in qualitative and evaluation research. Evidence supporting this model is drawn from in-depth youth and adult interviews in one of the largest policy/program evaluations undertaken in the United States, the Drug,…

The authors examined whether absolute and relative judgments about global-scale locations and distances were generated from common representations. At the end of a 10-week class on the regional geography of the United States, participants estimated the latitudes of 16 North American cities and all possible pairwise distances between them. Although…

Librarians rely on the Institute for Scientific Information's journal impact factor as a tool for selecting periodicals, primarily in scientific disciplines. A current trend is to use this data as a means for evaluating the performance of departments, institutions, and even researchers in academic institutions--a process that is now being tied to…

It is believed by some that most tests are multidimensional, meaning that they measure more than one underlying construct. The primary objective of this study is to illustrate how variations in the secondary ability distribution affect the statistical detection of dimensionality and to demonstrate the difference between substantive and statistical…

The Psychological well being Inventory (PWBI) is a multidimensional instrument that has enjoyed widespread use in a variety of research initiatives, from small-scale studies to national surveys. Recent empirical investigation of the measure has raised questions about its validity. This study examines the factorial validity of the Environmental…

J. E. Helms's (1995b) White racial identity theory is said to resemble a pseudoscience in certain respects because its empirical support is based on the White Racial Identity Attitude Scale (J. E. Helms & R. T. Carter, 1990) in spite of consistent evidence that the instrument does not measure the constructs that the theory proposes.

This article is a cross-validation of R. G. Tedeschi and L. G. Calhoun's (1996) original study of the development of the Posttraumatic Growth Inventory (PTGI). It describes several psychometric properties of scores on the PTGI in a sample of middle- to old-aged adults with a history of cardiovascular disease. The results did not support the…

This paper explores alternative approaches for facilitating efficient, evidence-centered item development for a new type of verbal reasoning item developed for use on the GRE® General Test. Results obtained in two separate studies are reported. The first study documented the development and validation of a fully automated approach for locating the…

Faced with selecting a geometry curriculum for our preservice elementary teacher mathematics course, we used a mixed-methods study to investigate the effectiveness, with respect to student achievement and student perception, of three reform-oriented curricula. ANCOVA results indicate students using one of the curricula scored significantly higher…

This study evaluated a "substantively driven" method for scoring NAEP writing assessments automatically. The study used variations of an existing commercial program, e-rater[R], to compare the performance of three approaches to automated essay scoring: a "brute-empirical" approach in which variables are selected and weighted solely according to…

A study demonstrated the utility of item analyses to investigate which items function well or poorly in a second language reading recall protocol instrument. Data were drawn from a larger study of 56 learners of German as a second language at various proficiency levels. Pausal units of scored recall protocols were analyzed using both classical…

Basic precepts for test development are described and explained as they are presented in measurement textbooks commonly used in the fields of education and psychology. The five building blocks discussed as the foundation of well-constructed tests are: (1) specification of purpose; (2) standard conditions; (3) consistency; (4) validity; and (5)…

Classroom teachers use intuitions, experiences, syllabi, and course guides to help implement a curriculum. Psychometric techniques can also help guide and shape curricula. Some psychometric techniques allow tests to reveal the actual curriculum mastered by students in an objective and sample-free manner and to indicate a probable learning sequence…

This paper presents analyses of score reliability for a mathematics placement test developed by the Mathematical Association of America in 1984 for use with undergraduate college students. Subjects included all 589 students seeking admission to the college mathematics curricula at a private university in the South during the course of the study.…

This paper reviews the application of the EM Algorithm to marginal maximum likelihood estimation of parameters in the latent class model and extends the algorithm to the case where there are monotone homogeneity constraints on the item parameters. It is shown that the EM algorithm can be used to obtain marginal maximum likelihood estimates of the…
