Audio feedback – better feedback?*
Susanne Voelkel & Luciane V. MelloSchool of Life Sciences
*funded by the eLearing Steering Group, UoL
“Feedback is one of the most powerful influences on learning
and achievement”*
* Hattie & Timperley, 2007
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
Good quality feedback – students’ view*
• Detailed information on how to improve• Applicable to future work• Personal• Timely
* Student focus group, School of Life Sciences
But…. all is not well!

Can audio feedback help us provide better feedback?
Research questions
• Will audio feedback– Work?– Save staff time?– Increase student satisfaction?– Help students learn better?
Research design
• Two case studies– Undergraduate level– Postgraduate level
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
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
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
Evaluation
• Questionnaire– Response rate• 44% undergraduate• 93% postgraduate
• Interviews (10, UG)• Marks (UG)
Did it work? The technical side.
• No problems from staff or student side

Written comments on audio feedbackUndergraduates
“It (the audio feedback) was very personal, I knew exactly what I had to do to make my mark better”
“…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”
“you get a lot more honest opinion about (your work) and a lot more information I think on how to improve”
Written comments on audio feedbackPostgraduates
“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”
