Oral presentation is one of the most widely used methods in assessing student learning outcomes of content comprehension and communication skills. Nevertheless, both students and teachers face challenges in optimizing the benefits of such learning activity.
From students’ perspective, they only receive a letter grade or numerical score but no feedback from the audience (teacher and classmates). From teachers’ perspective, students keep making the same mistakes throughout their course of study. Besides, students’ engagement in classmates’ presentations is problematic.
To address these issues, our team developed “Gongyeh 講嘢”—a peer feedback system for oral presentation. Gongyeh has 4 key features:
(1) the teacher simply uses a mobile device for video recording, and the audience uses their own mobile devices to provide real-time feedback;
(2) the feedback given by the audience is time-synchronized with the recorded video, which are available only to the presenter and teacher;
(3) the feedback is anonymous to the presenter as each audience is represented by a unique emoji, but the real identity is known to the teacher; and
(4) students give peer assessment marks according to rubrics preset by the teacher, so students have a better understanding of how their presentations are being graded. Apart from face-to-face presentation, Gongyeh allows asynchronous feedback with pre-recorded video.
