- 1. Audio feedback – better feedback?* Susanne Voelkel & Luciane V. Mello School of Life Sciences *funded by the eLearing Steering Group, UoL
- 2. “Feedback is one of the most powerful influences on learning and achievement”* * Hattie & Timperley, 2007
- 3. Effective feedback answers 3 questions*: • Where am I going? – (the goals) • How am I going? – “feed-back” • Where to next? – “feed- forward” * Hattie & Timperley, 2007
- 4. Good quality feedback – students’ view* • Detailed information on how to improve • Applicable to future work • Personal • Timely * Student focus group, School of Life Sciences
- 5. But…. all is not well!
- 8. UoL
- 9. Can audio feedback help us provide better feedback?
- 10. Research questions • Will audio feedback – Work? – Save staff time? – Increase student satisfaction? – Help students learn better?
- 11. Research design • Two case studies – Undergraduate level – Postgraduate level
- 12. 1. The undergraduate level project • Year 3, class size 70 • Low stake (10%) essay, exam conditions (handwritten) • Class split randomly in half – 50% written feedback (comments) – 50% audio feedback (bullet points on script) • Evaluation
- 13. 2. The postgraduate level project • M-level module • Class size 14 • Group work assessment – Individual component – Purely formative • All students receive audio feedback only • Evaluation
- 14. Methods • Recording the feedback – Mobile digital voice recorder – Audio files (mp3 format) – Measure time (UG) • Dissemination – By email • Listening to the feedback – Mp3 player or computer
- 15. Evaluation • Questionnaire – Response rate • 44% undergraduate • 93% postgraduate • Interviews (10, UG) • Marks (UG)
- 16. Did it work? The technical side. • No problems from staff or student side
- 17. Did audio feedback save staff time? Time (min) Standard N deviation Audio 16 +8 31 feedback Written 11 +3 31 feedback Significant difference (p=0.002)
- 18. Did audio feedback increase student satisfaction?

- 23. My feedback was clear Postgrad audio agree neither Under- disagree graduates written 0 20 40 60 80 100
- 24. Written comments on audio feedback Undergraduates “It (the audio feedback) was very personal, I knew exactly what I had to do to make my mark better” “you get a lot more honest opinion about (your work) and a lot more information I think on how to improve” “…written feedback means that you have it there just to look at all the time and it’s a bit harder to go back and look at the audio feedback”
- 25. Written comments on audio feedback Postgraduates “Audio FB was very useful, I strongly feel more lecturers should adopt it as part of their teaching methods” “Audio FB was fantastic and more detailed than just writing a few lines in text format”
