| Abstract | The "e-rater"® automated essay scoring system is used operationally in the scoring of "TOEFL iBT"® independent and integrated tasks. In this study we explored the psychometric added value of reporting four trait scores for each of these two tasks, beyond the total e-rater score.The four trait scores are word choice, grammatical conventions, fluency and organization, and content. Trait scores were computed on the basis of several criteria for determining feature weights: regression parameters of the trait features on human scores, reliability of trait features, and coefficients of features from a principal component analysis. In addition, augmented trait scores, based on information from other trait scores, were also analyzed.The psychometric added value of trait scores beyond total e-rater scores was evaluated by comparing the ability to predict a particular trait score on one task from the same trait score on the other task versus the e-rater score on the other task. Results supported the use of trait scores, and are discussed in terms of their contribution to the construct validity of e-rater as an alternative essay scoring method. (As Provided). |
