Analysis of mutual evaluation activity and student performance in creative project-based learning

Abstract

In this study, we analyzed mutual evaluation activities in a creative group learning lectures with some perspectives. Firstly, we analyzed correlations between personal achievements (mini-test, exercise) and group achievements (group works and presentations) for six years of lectures with Lego Mindstorms. From the result, we confirmed the significant correlations between oral presentations and demonstration. We also found the positive correlations between personal achievements and presentations. Secondly, we assessed correlations of students' mutual evaluation stats, rank correlations, and total scores. We confirmed the significance of correlation between average points and spearman rank correlations. A correlation between the standard deviation and the spearman rank correlation could be utilized to check the validity of mutual evaluations by students. Thirdly, we compared two types of peer-assessment activities, one in which learners were forced to enter comments and the other in which comments were optional. We confirmed that students with a larger standard deviation of the comment length are more serious about mutual evaluation.
