Peer reviewed Peer reviewed
Direct linkDirect link
Tendeiro, Jorge N.; Meijer, Rob R. – Applied Psychological Measurement, 2012
This article extends the work by Armstrong and Shi on CUmulative SUM (CUSUM) person-fit methodology. The authors present new theoretical considerations concerning the use of CUSUM person-fit statistics based on likelihood ratios for the purpose of detecting cheating and random guessing by individual test takers. According to the Neyman-Pearson…

How to Get Really Smart: Modeling Retest and Training Effects in Ability Testing using Computer-Generated Figural Matrix Items
Peer reviewed Peer reviewed

Freund, Philipp Alexander; Holling, Heinz – Intelligence, 2011
The interpretation of retest scores is problematic because they are potentially affected by measurement and predictive bias, which impact construct validity, and because their size differs as a function of various factors. This paper investigates the construct stability of scores on a figural matrices test and models retest effects at the level of…

Computerized Adaptive Testing: Revolutionizing Academic Assessment.
Peer reviewed Peer reviewed
Smittle, Pat – Community College Journal, 1994
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…

An Empirical Study of Computerized Adaptive Test Administration Conditions.
Peer reviewed Peer reviewed
Lunz, Mary E.; Bergstrom, Betty A. – Journal of Educational Measurement, 1994
The impact of computerized adaptive test (CAT) administration formats on student performance was studied with 645 medical technology students who also took a paper-and-pencil test. Analysis of covariance indicates no significant interactions among test administration formats and provides evidence for adjusting CAT test to more familiar modalities.…

The Nominal Response Model in Computerized Adaptive Testing.
Peer reviewed Peer reviewed
De Ayala, R. J. – Applied Psychological Measurement, 1992
A computerized adaptive test (CAT) based on the nominal response model (NR CAT) was implemented, and the performance of the NR CAT and a CAT based on the three-parameter logistic model was compared. The NR CAT produced trait estimates comparable to those of the three-parameter test. (SLD)

Bock, R. Darrell; Zimowski, Michele – 1991
The goals, principles, and methods of an individualized educational assessment are described as implemented in a 12th-grade science assessment instrument undergoing field trials in Ohio. Pilot tests were planned for December 1990 and March and April 1991. The assessment design incorporates the duplex design of R. D. Bock and R. J. Mislevy (1988)…
