Another blog I enjoy reading is Bluebird's Classroom. She is a middle school science teacher, which means we have just about nothing in common.
Honestly, though, I just like hearing about classroom experiences from another world. Middle school is, in fact, very different from high school, and I am frequently awed by the issues she meets and takes down in that world. She also taught in a geographic area roughly near my own, so I could commiserate with a lot of the experiences based on the area's demographics. There's a genuineness to her voice which I appreciate -- there's love for the kids but it's not syrupy; there's realism but it's not dire. A nice balance I hope I can one day master!
