Smartphones combine the flexibility of MP3 recorders and the connectivity of a PC in a discrete handheld device, thereby suggesting their application as a user friendly tool for giving recorded audio feedback efficiently. This paper describes a smartphone feedback methodology and presents findings from research on its use with 130 Level 5 (2nd year of degree study) Engineering and Computing students. The study found that the smartphone was more suitable than other technologies to the various demands of feedback production and distribution, and that this helped the tutor to manage the exceptionally stressful time associated with marking and giving feedback on top of an ongoing teaching load. Its pedagogic integration also resulted in a good dialogical experience as evidenced through student testimony.
