I think VoiceThread is a wonderful application for ESL/EFL students. In fact, I named it the number one Best Web 2.0 Application for ESL/EFL Learners– 2007.

However, I don’t think their site makes it that easy to understand how teachers can use it most effectively.

Now Silvia Tolisano has written an extensive post, including many screenshots, that is clearly the best explanation I’ve seen on how teachers can use this web tool.
