Twitter for teachers. I learn so much by simply talking to teachers in the building. How much more can I learn by talking to teachers from around the world?
From personal experience...
For the past year, I have enjoyed sharing my ideas with other educators. Likewise, I have have been overwhelmed by the knowledge that I have taken from other teachers. My computer is full of "links" and "favorites" based on Twitter alone.
Teachers from all around the world can share advice and experiences.It is an amazing thing.
