Using Peer Grading to Improve the Objectivity of Grades in GUI Design Courses

This paper deals with examining the possibility of peer grading when ranking graphical user interface (GUI) design images. The assessment was made on real images created by students on a GUI design course. Students' assignments to design a graphical user interface were being subjected to pairwise comparison and ranking was made based on pairwise comparison matrix. Obtained students' ranking was compared to experts' opinion using Spearman's and Kendall's metrics. The results suggest the possibility of using students' peer to peer grades to obtain objective rank from their subjective comparisons.
