The purpose of the book is to provide teachers of psychology access to teaching techniques that epitomize "happy tact and ingenuity." The principle influence that teachers have on student behavior occurs in the classroom since, as noted by Erickson and Strommer, (1991), today's students spend relatively little time studying outside of class. When…

A number of explanations have been offered for the differences in test performance among various population subgroups. This paper begins with a discussion of these explanations including the psychometric explanation that group differences are due to bias in the test. An overview of bias research argues that results to date are inconclusive. A…

This digest presents a list of recommendations for writing multiple-choice test items, based on psychometrics statistics are typically provided by a measurement, or test scoring, service, where tests are machine-scored or by testing software packages. Test makers can capitalize on the fact that "bad" items can be differentiated from…

Three important methods areas of multivariate analysis that are not always thought of in terms of latent variable constructs, but for which latent variable modeling can be used to great advantage, are discussed. These methods are: (1) random coefficients describing individual differences in growth; (2) unobserved variables corresponding to missing…

Three types of data were factor analyzed using principal components extractions with orthogonal and oblique rotations to test publisher claims for construct validity of the Personal Profile System (PPS). Behavioral descriptor data from 1,045 senior non-commissioned Air Force officers were factored as raw data, mean corrected data, and standardized…

A cognitively based theoretical framework for the assessment of domain competence is proposed. The basic thesis is that to be knowledgeable one must know how the important concepts of a domain are interrelated. This thesis implies that any valid assessment of knowledge must capture these structural properties. The implementation of a structural…

Many data analysis problems in psychology may be posed conveniently in terms which place the parameters to be estimated on one side of an equation and an expression in these parameters on the other side. A rule for improving the rate of convergence of the iterative solution of such equations is developed and applied to four problems. (Author/RC)

This paper highlights the need for a systematic, content aware, and theoretically-based approach to test design. The cognitive components approach is endorsed, and is applied to the development of a computerized perceptual speed test. Psychometric literature is reviewed and shows that: every major multi-factor theory includes a clerical/perceptual…

Intended as a resource for individuals wishing to evaluate stress management programs, this handbook, one of a series of seven, provides a collection of measuring devices that can improve the quality of such evaluations. Chapter 1 introduces the handbook's contents and outlines evaluation related issues specific to stress management programs.…

The effectiveness of 19 methods of smoothing was investigated as those methods apply to the equipercentile method of test equating. Seven methods involved smoothing the score distribution before the tests were equated (presmoothing). Seven involved smoothing the resultant points after the equating (postsmoothing). Five methods involved combining…

The models and procedures discussed in this paper are related to those presented in Bock and Aitkin (1981), where they considered the 2-parameter probit model and approximated a normally distributed prior distribution of abilities by a finite and discrete distribution. One purpose of this paper is to clarify the nature of the general EM (GEM)…

Quality of performance data yielded by subjective judgment is of major concern to researchers in performance appraisal. However, some confusion exists in the analysis of quality on ratings obtained from different rating scale formats and from different raters. To clarify this confusion, a study was conducted to assess the quality of judgmental…

This procedure for testing the mastery of programming skills uses online testing and correction. The student is presented with a test problem and is asked to solve it, encode the solution, debug the code, and save it on a floppy disk. The instructor corrects the program at the appropriate points through the use of REM statements. The erroneous or…

Measures of the Halstead-Reitan Neuropsychological Battery (HRNB) were factor analyzed with subtests of the Halstead Category Test (HCT) for 277 9-year-old learning disabled subjects. Eight factors with eigenvalues greater than one were rotated to a final solution that accounted for 67.9 percent of the total variance. HCT-Subtest 1 loaded…

Results of administering Piagetian tests of concrete and formal operations to 6- to 11-year-olds whose IQ's were in excess of 160 support the reality of Piaget's stage structures but suggest that the speed with which tasks within a stage are mastered is a function of intelligence in the psychometric sense.
