Twitter is a game changer. I am constantly amazed at how quickly you can connect with other educators around the world. One of the people you might consider following is Richard Byrne. He is a Google certified teacher and author of the "Free Technology for Teachers" blog at http://www.freetech4teachers.com. Spend some time exploring the posts on his blog and the links that he suggests. What did you discover? What would be useful in your classroom? I completely agree that Twitter is a game changer. After exploring his site there are so many different posts on different topics that I am interested in. I am lucky enough to teach in a district where our technology coordinators are also google certified and are absolutely amazing. They have completely changed my teaching in these last few years and I am better because of them. I was already using Twitter, but for personal use and after meeting them and learning from them I have changed my use of Twitter to professional use and it truly is amazing. I have had the opportunity to connect with so many educators with the same philosophy and beliefs as me and learned from them. I have been able to collaborate with people around the world!
