For this purpose an experiment was conducted: 165 students were asked to deliver a presentation and their presentations were assessed by fellow students. The results of this study can be summarized as follows: (1) Factor analysis extracted three factors(organization of the content,expression style and regard to audience) for presentation evaluation. (2) The internal consistency for presentation evaluation was high(Cronbach �� = .880) and Cronbach ��for each 3 subtests ranged from .671 to .801.
