Have a class web page which your students can contribute to by ringing a local phone number and speaking. Whatever they record appears at the class website.
You can see an example at http://wordsworthreflections.wordpress.com
In the tutorial I show, step by step, how to:
1. Set up a free website with wordpress.com
2. Register students with utterli.com, also free, so when they ring a local phone number, they’re recognised and can record audio over the phone. The audio is automatically published at the website.
This requires no technical expertise by the teacher. I show everything you need in the video.
