In addition, the students in the study group were asked to write critical articles and the written products were evaluated through the developed scoring key. The collected data were analyzed with a statistical program. In order to ensure internal consistency in the research, Cohen's Kappa coefficient was determined in order to determine the reliability of the evaluations of the raters who scored the data. Cronbach Alpha coefficient was determined in order to determine that the dimensions and items in the developed rubric were items that were consistent with each other and that examined the same feature. As a result of the findings, it was concluded that there was a high level of consistency between the evaluations made by different raters. In addition, in line with the expert opinions received during the development of the rubric, It was concluded that the rubric exactly measured what was intended to be measured and the rubric was valid and reliable.
