Multivariate Behavioral Research Vol. 26, No. 3 (1991) pp. 457–77
In a simulation study, factor analysis and multidimensional item response theory (IRT) models are compared with respect to estimates of item parameters. For multidimensional data, a common factor analysis on the matrix of tetrachoric correlations...
Applied Psychological Measurement Vol. 31, No. 3 (2007) pp. 213–232
The early stage of computerized adaptive testing (CAT) refers to the phase of the trait estimation during the administration of only a few items. This phase can be characterized by bias and instability of estimation. In this study, an item selection ...
Journal of Educational and Behavioral Statistics Vol. 22, No. 2 (1997) pp. 203–26
Some alternative criteria for item selection in adaptive testing are proposed that take into account uncertainty in the ability estimates. A simulation study shows that the likelihood weighted information criterion is a good alternative to the...
The D-Optimality Item Selection Criterion in the Early Stage of CAT: A Study with the Graded Response Model
Journal of Educational and Behavioral Statistics Vol. 33, No. 1 (2008) pp. 88–110
During the early stage of computerized adaptive testing (CAT), item selection criteria based on Fisher"s information often produce less stable latent trait estimates than the Kullback-Leibler global information criterion. Robustness against early...
The Effectiveness of Propositional Manipulation as a Lecturing Method in the Statistics Knowledge Domain
Instructional Science: An International Journal of the Learning Sciences Vol. 41, No. 6 (November 2013) pp. 1127–1140
The current experiment examined the potential effects of the method of propositional manipulation (MPM) as a lecturing method on motivation to learn and conceptual understanding of statistics. MPM aims to help students develop conceptual...
