This study investigated the applicability to computerized adaptive testing (CAT) data of a differential item functioning (DIF) analysis that involves an empirical Bayes (EB) enhancement of the popular Mantel Haenszel (MH) DIF analysis method. The computerized Law School Admission Test (LSAT) assumed for this study was similar to that currently…

This paper applies specific information item selection using a method developed by T. Davey and M. Fan (2000) to a multiple-choice passage-based reading test that is being developed for computer administration. Data used to calibrate the multidimensional item parameters for the simulation study consisted of item responses from randomly equivalent…

In a computerized adaptive test (CAT), it would be desirable to obtain an acceptable precision of the proficiency level estimate using an optimal number of items. Decreasing the number of items is accompanied, however, by a certain degree of bias when the true proficiency level differs significantly from the a priori estimate. G. Raiche (2000) has…

A method based on 0-1 linear programming (LP) is presented to stratify an item pool optimally for use in "alpha"-stratified adaptive testing. Because the 0-1 LP model belongs to the subclass of models with a network-flow structure, efficient solutions are possible. The method is applied to a previous item pool from the computerized…

Children aged 7 to 14 years were administered a computerized version of the Raven's Coloured Progressive Matrices test. Computer and traditional version performance was found to be similar in terms of total mean score, correlation with the WISC-R, Raven's subscale intercorrelations, and Raven's total mean score composition.

Describes tailored testing (in which a computer selects appropriate items from an item bank while an examinee is taking a test) and shows it to be superior to paper-and-pencil tests in such areas as reliability, security, and appropriateness of items. (IRT)

Developed a multilevel item response (IRT) model that allows for differences between the distributions of item parameters of families of item clones. Results from simulation studies based on an item pool from the Law School Admission Test illustrate the accuracy of the item pool calibration and adaptive testing procedures based on the model. (SLD)

Compared student performance on computer-based assessment to machine-graded multiple choice tests. Found that performance improved dramatically on the computer-based assessment when students were not required to scroll through the question paper. Concluded that students may be disadvantaged by the introduction of online assessment unless care is…

Studied the relationship between test mode (paper and pencil or computerized with and without editorial control) and computer familiarity for 222 undergraduates. Results emphasize the importance of evaluating time constraints when converting exams from paper to computer delivery. (SLD)

Examined the equivalence of two versions of the Strong-Campbell Interest Inventory (SCII) using four combinations of paper-and-pencil and computer administrations with college student subjects (N=75). Found slightly better test-retest reliability for the computer-based SCII. (Author/ABL)

Assessed equivalence of paper-and-pencil and computer versions of the Self-Directed Search (SDS) for 62 college students. The results showed a significant positive correlation in SDS scores for the two SDS forms; however, users strongly preferred the computer format. (Author)

Introduces a theoretical framework for mastery testing, using Item Response Theory and Bayesian Decision Theory. The idea of sequential testing is developed, with the goal of providing longer or shorter tests as needed, and a computerized application to a hypothetical professional knowledge examination is discussed. (Author/LRW)

Describes a study of 52 male inmates in Ontario (Canada) that was conducted to compare paper-and-pencil versus computer-based formats of the State-Trait Personality Inventory, the Anger Expression Scale, the Belief Scale, and the Vengeance Scale. The validity of assessments of incarcerated individuals regardless of administration modality is…

A computerized hearing aid measurement system using simulated input and output compression hearing aids was compared to a manual technique using conventional laboratory instrumentation. Results matched closely, but the computer system was considerably more flexible and easier to use. (Author/DB)

Studied the cross-mode equivalence of paper-and-pencil and computer-based clerical tests with 141 undergraduates. Found no differences across modes for the two types of tests. Differences can be minimized when speeded computerized tests follow the same administration and response procedures as the paper format. (SLD)
