Summary: | This study aimed to examine the effect of rater training on the differential rater function (rater error) in the
process of assessing the academic writing skills of higher education students. The study was conducted with a
pre-test and post-test control group quasi-experimental design. The study group of the research consisted of 45
raters, of whom 22 came from experimental, and 23 came from control groups. The raters were pre-service
teachers who did not participate in any rater training before, and it was investigated that they had similar
experiences in assessment. The data were collected using an analytical rubric developed by the researchers and
an opinion-based writing task prepared by the International English Language Testing System (IELTS). Within
the scope of the research, the compositions of 39 students that were written in a foreign language (English) were
assessed. Many Facet Rasch Model was used for the analysis of the data, and this analysis was conducted under
the Fully Crossed Design. The findings of the study revealed that the given rater training was effective on
differential rater function, and suggestions based on these results were presented. |
