Harrison, David A. – Journal of Educational Statistics, 1986
Multidimensional item response data were created. The strength of a general factor, the number of common factors, the distribution of items loadingon common factors, and the number of items in simulated tests were manipulated. LOGIST effectively recovered both item and trait parameters in nearly all of the experimental conditions. (Author/JAZ)

DeAyala, R. J.; Koch, William R. – 1986
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…

McKinley, Robert L.; Reckase, Mark D. – 1980
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…

Vale, C. David; Gialluca, Kathleen A. – 1985
ASCAL is a microcomputer-based program for calibrating items according to the three-parameter logistic model of item response theory. It uses a modified multivariate Newton-Raphson procedure for estimating item parameters. This study evaluated this procedure using Monte Carlo Simulation Techniques. The current version of ASCAL was then compared to…

Olsen, James B.; And Others – Journal of Educational Computing Research, 1989
Describes study that was designed to compare student achievement scores from three different testing methods: paper-administered testing, computer-administered testing, and computerized adaptive testing. The California Assessment Program (CAP) item banks for grades three and six which this study incorporated are described, and results are…

Thompson, Janet G.; Weiss, David J. – 1980
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…
