摘要:Computerized adaptive testing (CAT) has become popular in recent years due to the modern computer technology. Like conventional paper and pencil (P&P) testing, the primary goal of computerized adaptive tests (CATs) is to make inferences about the proficiency of examinees that a test seeks to measure. In CAT, test items are adapted to the proficiency level of the individual examinees. One of the conditions in item selection is to choose items with the maximum test information function, that is, with the minimum standard error of measurement (SEM) or with the shortest confidence interval (CI) for proficiency. Thus, accurate SEMs and CIs for proficiency are required for obtaining an appropriate set of items and to report scores in CAT. In CAT research, many studies (e.g., Wang & Vispoel, 1998; Yi, Wang, & Ban, 1999) have examined the characteristics of different proficiency estimation methods. The research on procedures for constructing CIs is limited. Furthermore, no research on item selection based on the shortest CI has been found. Via simulation studies under unit-dimension and multi-dimension environments, the current study intended to investigate these procedures The 76th Annual and the 17th International Meeting of the Psychometric Society Page 213 under various CAT conditions. The proposed methods for constructing CIs for proficiency will be applied to the item selection procedure in a simulated CAT. This study intends to provide users with most accurate CIs for proficiency, thus items are appropriately selected and the accuracy of the score report in CATs is improved.
