Designing a Virtual Item Bank Based on the Techniques of Image Processing
Liao, Wen-Wei; Ho, Rong-Guey
Turkish Online Journal of Educational Technology - TOJET, v10 n4 p93-106 Oct 2011
One of the major weaknesses of the item exposure rates of figural items in Intelligence Quotient (IQ) tests lies in its inaccuracies. In this study, a new approach is proposed and a useful test tool known as the Virtual Item Bank (VIB) is introduced. The VIB combine Automatic Item Generation theory and image processing theory with the concepts of figural tests and Computerized Adaptive Testing (CAT). It is believed that this tool will assist in improving traditional figural tests--in terms of solving previous issues relating to item exposure and allowing a figural test to be more easily developed. (Contains 6 figures and 9 tables.)
