Spotting Incorrect Rules in Signed-Number Arithmetic by the Individual Consistency Index.
Abstract
This study demonstrates that even a criterion-referenced test, in which items are chosen from a single content domain, requires a close examination of construct validity. The Individual Consistency Index (ICI) is effective in detecting anomalous response patterns resulting from some misconception(s). The subset obtained by deleting the responses which were spotted by ICI showed a higher unidimensionality. The same result was replicated by another data set whose test was parallel but not identical to the previous one. Although computerized error diagnostic programs can identify misconceptions possessed by a student in very specific domains of arithmetic, ICI can be applicable to more general domains and detect possible candidates to route to the expensive error-diagnostic programs.
