Tracii Ryan is a research fellow in the Faculty of Education, Monash University, and in the Melbourne Centre for the Study of Higher Education, The University of Melbourne. Tracii has research expertise relating to the motivations, outcomes and individual differences associated with social media and educational technologies. Michael Henderson is an associate professor and the director of Graduate Studies in the Faculty of Education at Monash University. He researches and teaches on the topics of educational technology and instructional design, including ethics of social media use and assessment feedback designs. Michael Phillips is a senior lecturer in the Faculty of Education at Monash University. His research explores the complexity of engaging educators in higher education and schools in professional learning. In addition to his work on teacher's knowledge, he has developed a national profile in multimodal assessment feedback. 2015). This reconceptualisation of feedback positions the learner at the centre of the process, and highlights two essential features of effective feedback. The first is that learners are able to comprehend and make sense of the information they receive, and the second is that they have the motivation and opportunity to subsequently act upon that information to progress their learning (Carless & Boud, 2018). These goals are difficult to achieve, and the content of the feedback Abstract Assessment feedback is increasingly being provided in digital modes, from electronic annotations to digital recordings. Digitally recorded feedback is generally considered to be more detailed than text-based feedback. However, few studies have compared digital recordings with other common feedback modes, including non-digital forms such as face-to-face conversations. It is also unclear whether providing multiple feedback modes is better than a single mode. To explore these possibilities, an online survey asked 4514 Australian university students to rate the level of detail, personalisation and usability of the feedback comments they had most recently received. Of the students who received a single feedback mode only, electronic annotations and digital recordings were rated most highly on the three quality indicators. Students who received multiple modes were more likely to agree with all three indicators than those who received a single mode. Finally, students who received multiple modes were more likely to agree that the comments were detailed and usable when one of those modes was a digital recording. These findings enhance our understanding of feedback design, indicating that it is important to consider the strengths and weaknesses of particular modes, and the value of offering multiple modes.
