Jing and Skype are two more ways of improving collaboration and communication in the classroom to go around the world.
Skype can provide field trips in class, talking to the author of a favorite book, or communicating with a student from another part of the world. It's endless.
With Jing the capturing of videos and the clarification of on line conversation could be used at any level. Image capturing and uploading to other video sites will be so exciting for the students and of course they are open to figure out even more ways to use it.
