Recently I have discovered the wonderful world of Voicethreads! It is a simple tool in which students can collaborate on projects through the recording of their voices or the adding of text around a slide / slides. And not to mention – it is good fun too!
For an example you can have a look at this Kids Speak Voicethread we took part in: http://globalclassroom2011-12.wikispaces.com/Kids+Speak%21+2011-2012
Or simply visit www.voicethread.com and get started.
