Audio-blogging ...

Hi Folks,
Welcome to audio-blogging ...
I am in Jupiter Team, so what music to choose . . . Have you seen Gustav Holst ?
You can use audio files uploaded to your blog, website, hyperlinked from inside a powerpoint or keynote presentation slide, or in your email, podcast, or simply keep them on your computer desktop or on CD , or DVD, to use at any time or any place. The code is a bit long - meaning that file size or time is limited. So it is best to make short small generic recordings that you can re-use whenever you need them.

Why would you want to use audio files ?
Well, listening to an invited expert in your field may enhance your college lecture and captivate your audience. You can explain the mating call of the lesser woodpecker, illustrate the difference between cockney and Brisbane accents.
You can present the difference between Mozart and Sibelius – not only showing their faces, their music writing, but now also examples of their sounds. Textual instructions will still be needed – for example “click below to listen to Mozart, and then Sibelius, and notice their different use of the long pitches at the end of the first crescendo. Replay if needed. Listen to the next recording and decide if it is Mozart or Sibelius”. Audio files can be uniquely useful and effective in online as well as in conventional education.

Why would you NOT want to use audio files ?
Audio files are not used much in online education because they are new and unfamiliar to the teacher. Teachers tend to merely upload their lecture notes to the course website - and audio is not effective for delivering pages 23 to 46 of the textbook. The file size of even one minute tends to be quite large. Students may find they need time to adjust to catch listening to your English – though they can easily re-play as often as they need. And remember the students faraway may not have the bandwidth infrastructure and playback software available and installed yet.
Teacher time is expensive, and the script if any needs to be carefully prepared with redundant phrases removed. Repetition and re-phrasing commonly used in speech for adding clarity can be deleted - since the student listener can just click on ‘re-play’. When used judiciously, audio can be extremely interactive and motivating to the student.
