Learning communities are a great idea for teaching. I thought that the book made a good point about teaching being a very isolating profession. I like the idea of collaboration with other teachers for better results and being able to come back after you've done to talk about the results of whatever you did and get feedback. It would help also because kids love doing things with other classes. It is memorable thing to bring classes together and work with students that they don't see everyday that whatever lesson you're working on they will remember. I also think that its beneficial for teachers because its a chance to share ideas and support one another in their teacher-y endeavors. Its a great way to do the penpal thing. Its also Is a good thing to maybe use Skype for things like meeting classroom to classroom. It's nice for students because they are getting a chance to interact and share ideas as well. Just like the teaching pluses, the students get support and get to share information and ideas towards the same goal. Working together is having a shared vision can be great. Science seems to be a big benefactor in a lot of these ideas. Because it is easy to share data and collect it from everywhere and bring it together. Like in the chapter it shows examples of kids collecting meteorological data or rainfall. Overall I think that learning communities is a great tool for teachers to share and connect with other teachers and expand thier horizons as well as their student's.
