Using a New Statistical Model for Testlets To Score TOEFL.
Wainer, Howard; Wang, Xiaohui
Journal of Educational Measurement, v37 n3 p203-20 Fall 2000
Modified the three-parameter model to include an additional random effect for items nested within the same testlet. Fitted the new model to 86 testlets from the Test of English as a Foreign Language (TOEFL) and compared standard parameters (discrimination, difficulty, and guessing) with those obtained through traditional modeling. Discusses the importance of assumptions of conditional independence. (SLD)
