Skype and Jing! I don't have any experience with either of these applications! Skype seems to be a little more involved and need a few more bells and whistles. Jing seems like a more reasonable option for my classroom. I think Jing would be a great way for students to keep up with a pen pal class! It would also be a fun way for kids to learn about the world outside of their own world. I think it would be a great way to expose our students to other cultures. Virtual field trips would be an outstanding way to utilize Jing. And as always, I'm sure my kiddos would have a million other ways to use this tool!
