Examination of the Assumptions and Properties of the Graded Item Response Model: An Example Using a Mathematics Performance Assessment.
Lane, Suzanne; And Others
Applied Measurement in Education, v8 n4 p313-40 1995
Over 5,000 students participated in a study of the dimensionality and stability of the item parameter estimates of a mathematics performance assessment developed for the Quantitative Understanding: Amplifying Student Achievement and Reasoning (QUASAR) Project. Results demonstrate the test's dimensionality and illustrate ways to examine use of the graded response model with performance data. (SLD)
