For those of you who have not yet subscribed to Education World as I have highly recommended, you would have missed Brenda Dyck's wonderful article about using Voice Thread in the classroom. There are some wonderful examples for you to look at and I am sure several of them will give you some ideas for using Voice Thread with your students. When you have a chance check out this article and take a look at the examples of Voice Thread used in various classrooms. The students are really proud to talk about their pictures. You can find the article here: http://www.education-world.com/a_tech/columnists/dyck/dyck023.shtml
Hope you are staying warm if you are in the midwest as I am - It was in the teens most of the day!
