| The present study reports the processes of development and use of an Analytic Dichotomous Evaluation Checklist (ADEC) which aims at enhancing both inter- and intra-rater reliability of writing evaluation. The ADEC consists of a total of 68 items that comprises five subscales of content, organization, grammar, vocabulary, and mechanics. Eight raters assessed the writing performance of 20 Iranian EFL students using the ADEC. Also, the raters were asked to rate the same sample of essays holistically based on Test of Written English (TWE) scale. To examine the inter-rater and intra-rater reliability of the ADEC, multiple approaches were employed including correlation coefficient, the dichotomous Rasch Model, and many-faceted Rasch measurement (MFRM). The findings of the study confirmed that the ADEC introduces higher reliability into scoring procedure compared with holistic scoring. Future research with greater number of raters and examinees may provide robust evidence to use analytic scale rather than holistic one. |
