A group of covariance structure models was examined to ascertain the similarity between conventionally administered and computerized adaptive versions of the Differential Aptitude Test (DAT). Results for 332 students indicate that the computerized version of the DAT is an adequate representation of the conventional test battery. (TJH)

Simulated data were used to investigate the performance of modified versions of the Mantel-Haenszel method of differential item functioning (DIF) analysis in computerized adaptive tests (CAT). Results indicate that CAT-based DIF procedures perform well and support the use of item response theory-based matching variables in DIF analysis. (SLD)

Discusses the development and use of a computer-adaptive test (CAT) for learners of Chinese. Each time the examinee answers a question, the CAT program registers the answer and, based on the examinee's response, decides whether the next question should be harder or easier. (23 references) (MDM)

Fifth and sixth grade children were assigned to three pretesting conditions: a full-length pretest, an adaptive pretest that exited learners when nonmastery was indicated, and a no pretest control. Learners in the adaptive treatment demonstrated higher levels of performance on the posttest and had greater motivation to continue the instruction.…

Discusses computerized adaptive testing, which is designed to provide students with an individualized examination adjusted to their skill levels. Indicates that scores are derived by comparing correct answers with the answers' difficulty rating. Highlights the advantages and disadvantages of the system and provides guidelines for successful…

A computerized adaptive test of word knowledge was administered over the telephone by reading items and response alternatives to 144 recent military enlistees who had completed the Armed Services Vocational Aptitude Battery. Correlations, factor loadings, and administration time indicate that the procedure is a good measure of crystallized verbal…

Reviews research literature on comparability issues in computerized adaptive testing (CAT) and synthesizes issues specific to comparability and test security. Develops a framework for evaluating comparability that contains three categories of criteria: (1) validity; (2) psychometric property/reliability; and (3) statistical assumption/test…

The Northwest Evaluation Association helped an Indiana school district develop a computerized adaptive testing system that was aligned with its curriculum and geared toward measuring individual student growth. Now the district can obtain such information from semester to semester and year to year, get immediate results, and test students on…

Effects of self-adapted testing (SAT), in which examinees choose the difficulty of items themselves, on ability estimates, precision, and efficiency, mechanisms of SAT effects, and examinee reactions to SAT are reviewed. SAT, which is less efficient than computer-adapted testing, is more efficient than fixed-item testing. (SLD)

This article discusses the main purposes of reading comprehension assessment and identifies the key features of good assessment. The article also identifies pitfalls that clinicians and educators should avoid to conduct valid assessments of reading comprehension, such as the degree to which the measure taps the constructive and integrative…

With advances in computerbased technologies and the emergence of elearning, there are unprecedented opportunities to reconsider assessment of learning (and, axiomatically, of teaching) and how this can be undertaken. One approach is adaptive assessment. Although it has existed in the tertiary environment since the time of the oral examination,…

We present principles for the design of an online system to support computer algebra enabled questions for use within the teaching and learning of mathematics in higher education. The introduction of a computer algebra system (CAS) into a computer aided assessment (CAA) system affords sophisticated response processing of student provided answers.…

A multiple choice test item is identified as flawed if it has no single best answer. In spite of extensive quality control procedures, the administration of flawed items to test-takers is inevitable. Common strategies for dealing with flawed items in conventional testing, grounded in the principle of fairness to test-takers, are reexamined in the…

The interest in the application of large-scale computerized adaptive testing has served to focus attention on issues that arise when theoretical advances are made operational. Some of these issues stem less from changes in testing conditions and more from changes in testing paradigms. One such issue is that of the order in which questions are…

Two-stage and multistage test designs provide a way of roughly adapting item difficulty to test-taker ability. All test takers take a parallel stage-one test, and, based on their scores, they are routed to tests of different difficulty levels in subsequent stages. These designs provide some of the benefits of standard computerized adaptive testing…
