Ten test films were developed to measure aspects of children's visual perception which are difficult to assess through conventional paper and pencil tests. The film medium was selected because it allows the presentation of temporal, as well as spacial, aspects of the stimuli. Four areas of perceptual performance covered in the films are: (1)…

Investigated empirically through post mortem item-examinee sampling were the relative merits of two alternative procedures for allocating items to subtests in multiple matrix sampling and the feasibility of using the jackknife in approximating standard errors of estimate. The results indicate clearly that a partially balanced incomplete block…

The primary objectives of this research program were the development of a battery of tests to investigate the effects of brain impairment on sensory and perceptual functioning. The Sensory-Perceptual Exam (SPE) contains measures intended to evaluate both relatively "pure" sensory functions, as well as those which involve more integrated…

Effects of item difficulty sequencing on performance and on post state anxiety were investigated using a timed mathematics aptitude test. The subjects were randomly assigned to a random, easy-to-hard, or hard-to-easy difficulty sequence group. The hard-to-easy sequence group performance was significantly lower than either the random or…

Although there are fundamental differences in the objectives of the two activities, the programing of instructional materials bears many similarities to the construction of tests. A systematic comparison of the problems and procedures reveals important implications for programing from the older field of testing. Theory and experience in test…

In order to verify that a test made of items selected from a pool produces the same Rasch scaled achievement scores as would be predicted from previous Rasch difficulty calibrations for those items, the following experiment was conducted. Seven math tests with similar content but graduated difficulty were administered to students in grade seven.…

Illustrates a multivariate approach to item analysis. Previous formulation is extended by investigating techniques simultaneously taking into account scale variance with the goal of reducing the average correlation between scales. Study examines problems in determining optimum values for combinations of item parameters selected for personality…

Describes the main features of computer-managed classes in psychology, statistics, and anthropology and the methodology that makes the computer-management possible. (Author/IRT)

Article discussed possible approaches to the question of how to design and accurately assess the construct validity of self-concept instruments. (Author/RK)

When the logistic function is substituted for the normal, Thurstone's Case V specialization of the law of comparative judgment for paired comparison responses gives an identical equation for the estimation of item scale values, as does the Rasch formulation for direct responses. Comparisons are made. (Author/CTM)

Three formulae developed to correct item-total correlations for spuriousness were evaluated. Relationships among corrected, uncorrected, and item-remainder correlations were determined by computing sets of mean, minimum, and maximum deviation coefficients and Spearman rank correlations for nine test lengths.

A generalization of the Rasch model is employed to quantify statements on a scale in the Thurstone tradition, as well as to measure a person's attitudes in the Likert tradition. An illustration of the technique is provided. (JKS)

The grade on a question of an answer-until-correct test is a function of the number of responses needed to find the correct response. This note considers how to assign credit for the number of responses needed to find the correct response. (Author/MP)

Elements that contribute to the construction of effective teacher-developed tests are noted, and practical suggestions for test construction are made. (MJB)

The use of matrix sampling to overcome the impracticality of the pair comparison method for obtaining scale values is empirically tested. Results indicate that matrix sampling is useful in such applications. (Author/JKS)
