Using Kernel Equating to Assess Item Order Effects on Test Scores
Moses, Tim; Yang, Wen-Ling; Wilson, Christine
Journal of Educational Measurement, v44 n2 p157-178 Sum 2007
This study explored the use of kernel equating for integrating and extending two procedures proposed for assessing item order effects in test forms that have been administered to randomly equivalent groups. When these procedures are used together, they can provide complementary information about the extent to which item order effects impact test scores, in overall score distributions and also at specific test scores. In addition to detecting item order effects, the integrated procedures also suggest the equating function that most adequately adjusts the scores to mitigate the effects. To demonstrate, the statistical equivalences of alternate versions of two large-volume advanced placement exams were assessed.
