The Assessment of Partial Knowledge: The Use of the Credit Model in Scoring Multiple-Choice Items.
Smith, Richard M.
One of the recurrent themes of the psychometric literature has been the idea that the incorrect responses a person makes to test items contain information that might be useful in determining the person's position on the variable the items are intended to define. The "Partial Credit" model, a member of the family of latent trait models proposed by Rasch, provides a means of assessing this partial knowledge while maintaining the desirable psychometric characteristics that all Rasch models enjoy. In this study the results of 30-item elementary algebra test are analyzed using the standard dichotomous scoring procedure and several procedures for assessing partial knowledge. The preliminary results indicate that the a priori ordering of distractors using integer weights provides useful information, particularly in the lower ability ranges. (Author/BW)
