Proposes an item-selection algorithm for neutralizing the differential effects of time limits on computerized adaptive test scores. Uses a statistical model for distributions of examinees' response times on items in a bank that is updated each time an item is administered. Demonstrates the method using an item bank from the Armed Services…

Evaluated the distribution of person fit within the computerized-adaptive testing (CAT) environment through simulation. Found that, within the CAT environment, these indexes tend not to follow a standard normal distribution. Person fit indexes had means and standard deviations that were quite different from the expected. (SLD)

Investigated three models that permit restricted examinee control over revising previous answers in the context of adaptive testing, using simulation. Two models permitting item revisions worked well in preserving test fairness and accuracy, and one model may preserve some cognitive processing styles developed by examinees for a linear testing…

Although instructional methods are moving in ever greater number to a multimedia base, testing is not. What principles should be considered in correcting this misalignment?

The paper uses both the author's experience of research training, and the empirical studies of autism in which he participated over the last 40-plus years, to derive research lessons and to consider the needs and prospects for future research. Attention is drawn to: the importance of mentors; the need to use technologies in a hypothesis-testing…

This paper examines the educational impacts of the Berkshire Wireless Learning Initiative (BWLI), a pilot program that provided 1:1 technology access to all students and teachers across five public and private middle schools in western Massachusetts. Using a pre/post comparative study design, the current study explores a wide range of program…

Computerized adaptive (CA) testing uses an algorithm to match examinee ability to item difficulty, while self-adapted (SA) testing allows the examinee to choose the difficulty of his or her items. Research comparing SA and CA testing has shown that examinees experience lower anxiety and improved performance with SA testing. All previous research…

Computerized adaptive testing for language teaching and learning takes advantage of two properties of the computer: its number-crunching and multiple-branching capabilities. Adaptive testing has also been called tailored testing because it aims at presenting items that suit the student's competence and that are informative, using an item bank and…

A number of challenges will be faced by the school testing community in the future. The content of achievement tests must match the curriculum, which changes its focus over the years. Test content should reflect expanding curriculum areas such as computer literacy, consumer skills, and critical thinking. Test publishers will provide data for…

This report provides an overview of the current applications of computer technology to construct test items and/or to formulate tests according to sound measurement principles. The test items may be computer-generated from strategies programmed by test constructors, or pre-constructed by item writers and stored in computer memory. The tests…

In April of 1982, the German Federal Armed Forces initiated the first empirical pilot project in the area of computerized adaptive testing (CAT). The configuration of hardware, psychological section, and physiological section is discussed, as well as two current problems (data transfer from the TEST 2000 microcomputer to a large sized computer for…

A conventional verbal ability test and a Bayesian adaptive verbal ability test were compared using a variety of psychometric criteria. Tests were administered to 550 Marine recruits, half of whom received two 30-item alternate forms of a conventional test and half of whom received two 30-item alternate forms of a Bayesian adaptive test. Both types…

A literature review was conducted to determine the current state of knowledge concerning the effects of computer administration of standardized educational and psychological tests on the psychometric properties of these instruments. Students were grouped according to a number of factors relevant to the administration of tests by computer. Based on…

A computerized flexilevel test was implemented and its ability estimates were compared with those of a Bayesian estimation based computerized adaptive test (CAT) as well as with known true ability estimates. Results showed that when the flexilevel test was terminated according to Lord's criterion, its ability estimates were highly and…

This research program was designed to investigate the applications of item response theory and computerized adaptive testing to the unique problems of the measurement of ability and the measurement of achievement. The research utilized a combination of monte carlo simulation studies and live-testing studies. The research approach for adaptive…
