Constructing An Item Bank Using Partial Credit Scoring, Geoff Masters
Prof Geoff Masters AO
A method for banking test items scored in several ordered response categories is described. Each item is seen as an ordered sequence of steps, and test forms are equated using the estimated difficulties of the steps in their shared items. Procedures for analyzing the internal consistency of individual links and for analyzing the coherence of an entire linking structure are described. The methodology is used to link six forms of a mathematics problem solving test.
