Rasch Based Analysis of Oral Presentation Assessment for Item Banking.
Nakamura, Yuji
The Rasch Model is an item response theory, one parameter model developed that states that the probability of a correct response is a function of the difficulty of the item and the ability of the candidate. Item banking is useful for language testing. The Rasch Model provides estimates of item difficulties that are meaningful, irrespective of ability level tested. Application of a many-faceted Rasch measurement model is one of the current issues in the language testing area. This paper explores what the Rasch model tells us in analyzing the multifaceted data of assessment in presentation classes, and focuses more specifically on the possible ways of constructing item banks for oral presentation classes so that teachers will know how difficult a set of test items is for the student-raters and how well those items can distinguish between the better and the poor students. This paper explores several areas of importance with respect to assessment, specifically, what the many-faceted Rasch Measurement Model tells us about the following factors: the relationship among the three facets of assessment (students, items, raters); rater severity/leniency; and students' ability. All of these questions are answered with extensive empirical basis for judgment. (KFT)
