This study examined computerized adaptive testing and cognitive ability testing of adults with cognitive disabilities. Adult subjects (N=250) were given computerized tests on language usage and space relations in one of three administration conditions: paper and pencil, fixed length computer adaptive, and variable length computer adaptive.…

This paper discusses equity issues that may arise from the widespread use of high stakes computerized testing. The literature relevant to computerized testing is examined from the perspective of equity concerns from within the framework of research and from the perspective of possible uses of computerized testing if equity issues are considered…

The strategies examinees employ when making item difficulty level choices in self-adapted computerized testing were investigated. Subjects were 148 college students (88 females and 60 males) in an introductory statistics course. The primary instrument was a self-adapted computerized algebra test used to measure student readiness for the statistics…

As part of a broad effort to improve the effectiveness and efficiency of embedded training environments, research was conducted using a Naval Tactical Data System (NTDS) console emulator. Objectives were to: (1) develop methodological guidelines for specifying the instructional content of training exercises to be embedded in NTDS consoles; (2)…

This study explores the test-retest consistency of computer adaptive tests of varying lengths. The testing model used was designed as a mastery model to determine whether an examinee's estimated ability level is above or below a pre-established criterion expressed in the metric (logits) of the calibrated item pool scale. The Rasch model was used…

The value of statistical research depends on valid comparisons which can usefully influence educational policy. Educational research needs to extend the measures of learning (such as the National Assessment of Educational Progress) through nationally-calibrated absolute measures and through computer-assisted and adaptive testing. Direct sampling…

Limitations seen in traditional educational procedures are discussed, and three new directions are suggested as being important emphases for testing. A new perception of measurement in which children have positions along particular concept dimensions or "lines" is discussed in terms of traditional testing notions including variables, item banks…

A study was conducted to compare tailored testing procedures based on a Bayesian ability estimation technique and on a maximum likelihood ability estimation technique. The Bayesian tailored testing procedure selected items so as to minimize the posterior variance of the ability estimate distribution, while the maximum likelihood tailored testing…

Three strategies for selecting number of instances needed to learn legal concepts were compared. An adaptive strategy required 25 percent less time and resulted in better post test performance than a partially adaptive strategy. The partially adaptive strategy was 16 percent more efficient than the nonadaptive strategy, and resulted in better…

Effects of altering test difficulty on examinee ability measures and test length in a computer adaptive test were studied for 225 medical technology students in 3 test difficulty conditions. Results suggest that, with an item pool of sufficient depth and breadth, acceptable targeting to test difficulty is possible. (SLD)

A mail survey about the use of instruments in 9 assessment areas was answered by 389 school psychologists. Comparison with a similar survey 10 years earlier suggests no decline in assessment overall, although emphasis is switching away from intelligence testing, toward achievement testing, behavior rating, and adaptive measurements. (SLD)

This report summarizes the design and development of an adaptive e-learning prototype for middle school mathematics for use with both sighted and visually disabled students. Adaptation refers to the system's ability to adjust itself to suit particular characteristics of the learner. The main parts of the report describe the system's theoretical…

A new testing strategy that provides protection against the problem of having examinees in adaptive testing choose difficulty levels that are not matched to their proficiency levels was introduced and evaluated. The method, termed restricted self-adapted testing (RSAT), still provides examinees with a degree of control over the difficulty levels…

This study assessed whether providing examinees with a choice between computerized adaptive testing (CAT) and self-adaptive testing (SAT) affects test performance in comparison with being assigned a CAT or SAT, and evaluated variables influencing examinee choice of either test form. The relative influences of test type and test choice on examinee…

This user manual describes procedures for using Version 3.0 Computerized Placement Tests (CPTs) software and provides information about the hardware required to operate it. The software features the College-Level Mathematics (CLM) test, Seamless Serial Testing branching capabilities, new system installation and uninstallation procedures, and new…
