Applications for Education
If you and your students have a class blog, Blog Talk Radio could be a great way to connect with other student bloggers around the world. Teachers can connect their class with another class to discuss any topic and gain alternative viewpoints on just about any topic. If you’re wondering how to connect with other classrooms around the world, try a service like ePals or use your Twitter (here’s a great example of teachers connecting with Twitter) network to find other teachers.
