Abstract

This study investigated the convergent validity of expert-system scores for four mathematical constructed-response item formats. A five-factor model comprised of four constructed-response format factors and a Graduate Record Examination (GRE) General Test quantitative factor was posed. Confirmatory factor analysis was used to test the fit of this model and to compare it with several alternatives. The five-factor model fit well, although a solution comprised of two highly correlated dimensions-GRE-quantitive and constructed-response represented the data almost as well. These results extend the meaning of the expert system’s constructed-response scores by relating them to a well-established quantitative measure and by indicating that they signify the same underlying proficiency across item formats. Index terms: automatic scoring, constructed response, expert system, free-response items, open-ended items.
