Writing about web page http://www.slideshare.net/faqs/slidecast
This is clever: if you want to publish teaching materials on the web, there’s a fair chance that it might involve audio and PowerPoint slides. Say for example that you’ve got an MP3 recording of a lecture you gave, and you’ve also got the PowerPoint slides you used during the lecture. What’s the best way to publish them? You could just upload them both to your site and leave it to your audience to figure out which slide goes with which part of the audio. Or you could use Captivate or Camtasia or whatever to create a narrated presentation.
But Slidehare have a neat tool they call Slidecasts where you upload a PowerPoint file and an MP3 file and then use a little tool they provide to synchronise the audio with the slides. It’s dead easy to use and the results can then be embedded on your blog or module page. Smart.
