High-quality public speaking skills convey strong and effective communication, a critical professional and workplace competency that positively impacts personal lives as well. Skill acquisition and mastery improve public speaking confidence, which in turn reinforces the speaker's abilities. Improving oral communication skills requires instruction, practice, feedback, and revision. We wanted to measure the effect of peer tutor feedback on the public speaking skills of undergraduate Business students at American University. We asked assessors unaffiliated with our office to independently rate both drafts and final submissions of one-minute video submissions completed by students in various sections of a Management and Organizational Behavior course. Our experiment shows that peer feedback significantly improves the quality of the final presentation, and that the positive impact is the same for native speakers of English than it is for non-native speakers.
