This case study aims to show how simple and powerful using audio feedback can be. Simon McIntyre from COFA Online, at The University of New South Wales discusses how he uses audio feedback effectively in his trans-national fully online Master of Cross-Disciplinary Art and Design program. While the context of this case study is in art and design, the use of audio files for giving students feedback is applicable to any discipline or almost any type of student work, even in 100% face-to-face classes. This case study will examine some of the motivations for adopting the use of audio feedback, the benefits for students and teachers, and some key considerations to keep in mind.
