The purpose of this paper is to report results on the development of a new computer-assisted methodology for creating parallel test forms using the item response theory (IRT) information function. Recently, several researchers have approached test construction from a mathematical programming perspective. However, these procedures require…

Expert systems can be used to aid decision making. A computerized adaptive test (CAT) is one kind of expert system, although it is not commonly recognized as such. A new approach, termed EXSPRT, was devised that combines expert systems reasoning and sequential probability ratio test stopping rules. EXSPRT-R uses random selection of test items,…

A computerized adaptive testing procedure for measuring mathematical skills of 60 deaf college students was evaluated. Ability estimates were compared for stability to those obtained earlier from conventional testing. Adaptive testing increased measurement efficiency by reducing test length. Student attitudes toward computerized testing were…

The development of a Spanish computerized adaptive placement test at Brigham Young University (Utah) is described. The test is based on an approach that locates an examinee's ability along a continuum of latent ability rather than determining the degree to which an individual's ability differs from the abilities of others taking the test, as in…

This report describes a study comparing the classification results obtained from a one-parameter and three-parameter logistic based tailored testing procedure used in conjunction with Wald's sequential probability ratio test (SPRT). Eighty-eight college students were classified into four grade categories using achievement test results obtained…

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…

This paper presents a new method for estimating a given latent trait variable by the least-squares approach. The beta weights are obtained recursively with the help of Fourier series and expressed as functions of item parameters of response curves. The values of the latent trait variable estimated by this method and by maximum likelihood method…

Discusses changes in testing as a result of the availability of extensive inexpensive computing and some recent developments in statistical test theory. Describes the role of the Computerized Adaptive Test (CAT) and modern Item Response Theory (IRT) in ability testing tailored to each student's knowledge and ability. (JAC)

Conventional mastery tests designed to make optimal mastery classifications were compared with fixed-length and variable-length adaptive mastery tests. Comparisons between the testing procedures were made across five content areas in an introductory biology course from tests administered to volunteers. The criterion was the student's standing in…

The Broad-Range Tailored Test (BRTT) is a computerized adaptive test. Each testee responds to 25 items; at the conclusion of the test the computer calculates a verbal ability score for the individual. The test was designed to yield a verbal ability score from the fifth grade level to the graduate school level. Two forms of the BRTT were…

Two types of computer-administered unit quizzes in a systematic pathology course for second-year medical students were compared. Quizzes composed of questions selected on the basis of a student's ability had higher correlations with the final examination than did quizzes composed of questions randomly selected from topic areas.

The feasibility of creating an item bank from a teacher-made test was examined in two comparable sections of a graduate-level introductory measurement course. The 67-item midterm examination contained multiple-choice and master matching items, which required higher level cognitive processes such as application and analysis. The feasibility of…

A live tailored achievement testing study was conducted to compare procedures based on the one- and three-parameter logistic models. Previous studies yielded inconclusive results because of the procedures by which item calibrations were linked and because of the item selection procedures. Using improved procedures, 83 college students were tested…

One question regarding the utility of adaptive testing is the effect of individualized item arrangements on examinee test scores. The purpose of this study was to analyze the item difficulty choices by examinees as a function of previous item performance. The examination was a 25-item test of basic algebra skills given to 36 students in an…

The relative validity of adaptive and conventional testing strategies using non-test variables as one set of external criteria was investigated. A total of 101 college students completed both a variable length stradaptive test and peaked conventional test; a second group of 131 college students completed a variable length Bayesian adaptive test…
