These days global education is a completely different ball game. There are countless programs that let you connect with foreign classrooms LIVE! Wow! The best way to learn about other people is to actually get to know them "unedited" so to speak. As an example I will use the Flat Classroom Project. This project is a program that allows students to connect with other students around the globe to create a project based on the work of Thomas Friedman. Friedman wrote a book called The World Is Flat, here is a video of a lecture he gave about this idea that the world is flat.
As a future teacher, all this talk about global education seems extremely overwhelming. I keep asking myself "how am I going to implement this kind of stuff?" or "How am I going to keep up with the changes in education?" It's important to remember that the teacher is also a learner. If you truly want to give your students a first rate education, then topics like global education are the topics to keep up with. It's so easy to find another teacher to connect with. Do yourself and your students a favor and set up authentic learning experiences with global learning in mind. It definitely has a positive effect on education. We CAN live as one world, we just have to take advantage of our resources to connect and get it done!
