Video recording is increasingly used in higher education settings to help students develop their oral presentation skills. However, little is known about the effect of video review for bringing about better high school student outcomes in oral presentation in formal (classroom) and informal (out-of-classroom) settings. Using a quasi-experimental design, this study investigated the effectiveness of using video review in developing the oral presentation skills of Grade 11 students in formal and informal settings in Singapore and how students felt about learning oral presentation skills in these settings. Students who viewed their oral presentations in a formal setting had significantly higher effectiveness of group presentation scores than those who viewed them in informal settings using mobile devices. Their presentations were rated more effective, cohesive, and organised. However, students found viewing their oral presentations in informal settings to be effective, engaging, convenient, and that it provided immediate feedback.
