  1. Audio Recordings of Lectures as an E-Learning Resource Jim Balfour – SBE

  2. Overview • Why Now? • Why bother? • The Downside! • The Process • Pull of Push? • Student Reaction • Conclusion

  3. Why now? what’s changed? In a word – Technology • Personal music players (e.g. iPods) allow digital audio to played anywhere, any time • Consumer electronics make recording audio cheap and easy • Free (or almost free) audio editing software makes it quick and easy to ‘chunk-up’ a recording • VLEs, LMSs, etc make audio delivery over the web accessible to anyone with a web connection

  4. Advantage to students when • A lecture is missed • English is not the first language • Baffled first time through • Annotating lecture notes after the ‘event’ • Attempting tutorial questions/revision • Engaged in distance and/or part-time learning • Suffering from some special need (e.g. impaired hearing)

  5. Advantages for staff • Professional Development • Student engagement • Encourages independent learning • Less ‘knocks on the door’ • Big potential for distance learning delivery • Lower failure rates? • It’s sustainable!

  6. The Downside! • More technology • Staff time • Hardware costs • Software costs • Might ‘encourage’ students to miss lectures

  7. The Process Record lecture (128 kbs) Move file from MP3 player to PC ‘Chunk-up’ audio file using WavePad Save files from WavePad files as 24 kbs MP3s Upload 24 kbs MP3 files to VLE Click boxes for Additional slides

  8. Pull or Push? • Pull relies on students downloading (or streaming) the audio files • Push (or Podcasting) requires Podcasting software on the student’s computer that will automatically download new content from a Podcast server

  9. Results of Questionnaire Survey • 2 out of 3 students responded • The resource was not universally used (55%) • Many who did not use the resource thought it would have helped them to learn (40%) • The audio files were found to be Useful (3) on a scale Not Useful at All (1) to Extremely Useful (5) • No measurable difference in exam performance between listeners and non-listeners • The ‘freshness’ of the audio files is regarded as important

  10. Conclusions • Making audio recording of lectures available to students is now easy, quick and inexpensive • The contribution to student learning made by the files justifies the effort of producing them, i.e. they have a high Value Added Ratio Total Learning Enhancement Value Added Ratio = Cost of Production and Delivery
