This paper presents an empirical study investigating the use of instant online feedback on face-to-face presentations. This innovative way of using information technology for the specific communication purpose of giving feedback was researched in the context of a university course on “Human-Computer Interaction and Psychology”. A total sum of 80 students majoring in Computer Science participated in the instant online feedback activity and 907 feedbacks were given. 72 students returned the questionnaire for evaluating this educational scenario. Quantitative and qualitative analysis revealed that students seem to prefer giving feedback online in addition to a face-to-face setting for reasons like possible anonymity and more honesty. Study results further demonstrate that instant online feedback may facilitate students' interest in and commitment to their presentations, finally also increasing their contributions' quality.
