Those of you teaching online or blended courses know the value of tools that encourage interaction.  VoiceThread is one such tool.

VoiceThread allows you and your students to comment on a digital object.  You can comment on documents, images, or videos.  You can comment via text, telephone, webcam, or microphone.  Check out this example of a voice commentary on a still image (courtesy of the Franco-American Collection, University of Southern Maine).

Try out VoiceThread for yourself.  Then you can truly decide where it belongs in your particular online tool kit (or sewing kit).
