An Empirical Examination of the IRT Information of Polytomously Scored Reading Items under the Generalized Partial Credit Model.
Donoghue, John R.
Journal of Educational Measurement, v31 n4 p295-311 Win 1994
Using the generalized partial-credit item response theory (IRT) model, polytomous items from the 1991 field test of the National Assessment of Educational Progress reading test were calibrated with multiple-choice and open-ended items. Polytomous items provide more information than dichotomous items. (SLD)
