Abstract
The purpose of this study is to investigate whether students’ oral presentation skills
affect their ability to rate presentations delivered by peers. The author examined the
correlation between peer assessment and teacher assessment with reference to the
participants’ presentation skills. In four separate classes, the teacher and participants
evaluated individual students. Both teacher and 61 students used prepared evaluation
sheets, and the correlation of student evaluation and teacher evaluation was obtained.
Based on the teacher evaluation, students were divided into upper, middle, and lower
presentation ability groups. The evaluation of individual students in each group was
correlated to the teacher’s evaluation. A moderate overall correlation was found between
peer assessment and teacher assessment (r =.529～.606), with little difference among
the three groups. It was thought that the higher ability group would grade more closely
to the teacher, but this was not the case. These results indicate that the rating ability of
students was not related to their presentation skills. In addition, some tendencies for peer
assessment were examined. In general, students tended to be more lenient compared to
the teacher. Also, students tended to give evaluations that were close to their own
perceived level of performance.
