Extending the Sato Caution Index To Define the Within and Beyond Ability Caution Indexes.
D'Costa, Ayres
The Sato Caution Index takes into account the number and difficulty of items gotten wrong by a student within his or her ability, as well as the number and difficulty of items gotten right beyond his or her ability. Sato subtracts the two components to define a single Caution Index. In this study, the components are kept separate, defining a Within Ability Concern Index (W) and a Beyond Ability Surprise Index (B). Using data from 10-item testlets taken by 121 college students, the critical information made available by using the B and W Indexes in addition to the Sato Index is identified. The relationships of the three indexes to total score and the number of errors committed by the students within ability-level are examined. Factor analysis reveals that the new indexes can add a new dimension to test performance information provided by the Sato Index. Five tables provide analysis data. (Author/SLD)
