The concept of self-directed learning has become increasingly important in educational and work organizations as a result of trends that require learners to become more responsible for their own learning to remain highly skilled and knowledgeable in a competitive marketplace. To assess self-directedness in the Korean context, a relatively new…

This paper discusses the use of two theories of item analysis and test construction, their strengths and weaknesses, and applications to the design of the Hawaii State Test of Essential Competencies (HSTEC). Traditional analyses of the data collected from the HSTEC field test were viewed from the perspectives of item difficulty levels and item…

When evaluating the utility of a psychological test for clinical decision making, both the psychometric properties of the test (i.e., the reliability and validity of the instrument) and the ambiguity of the language by which test results are interpreted or communicated need to be considered. Although each has been studied independently, to date…

This handbook explains how to do Rasch measurement. The emphasis is on practice, but theoretical explanations are also provided. The Forward contains an introduction to the topic of Rasch measurement. Chapters 2, 4, 5, and 7 use a small problem to illustrate the application of Rasch measurement in detail, and methodological issues are considered…

The purpose of this technical manual is to document the technical aspects of the 2002-2003 Maine Educational Assessment (MEA). In the fall of 2002, students in grades 4, 8, and 11 participated in the administration of the MEA in writing, reading, and health education.

Discusses social impact of IQ used as concrete reference point; promotes a phenomenological approach to psychological development. (ST)

The Rasch model is an item analysis model with logistic item characteristic curves of equal slope, i.e. with constant item discriminating powers. The proposed goodness of fit test is based on a comparison between difficulties estimated from different scoregroups and over-all estimates. (Author)

Paper presents normative data on the Mathematics Anxiety Rating Scale (MARS), which measures anxiety associated with number manipulation or mathematics concepts. (Authors)

An average of the two scores on the LIPS and PPVT provides an estimate of current IQ comparable to that which might be obtained by a WISC or S-B. (Authors/MB)

Article examines the effects of nonreinforced trials during presolution of a concept identification task. (Author/ML)

Estimates of the validity of random short forms can serve as benchmarks against which to appraise the validity of particular short forms. Formulas are presented for estimating the validity of random short forms and illustrated with Wechsler Adult Intelligence Scale-Revised (WAIS-R) and Minnesota Multiphasic Personality Inventory data. (Author/CM)

Cognitive component research on aptitudes has shown that performance on test items depends on a series of processing events. Each processing component potentially defines a separate construct that contributes to item and subject differences in performance. This article presents the multicomponent latent trait model for measuring these component…
