Reading blogs of other teachers gives me a window into other classrooms. Teaching is a fairly isolated profession and I rarely have the opportunity to see what is happening in classrooms other than my own. (Although I do think that I are more aware of other classroom practices at my school because of how much planning we do as teams or in small groups.)
I've been wondering why I find other teacher blogs so compelling when all I am doing is reading about their days. I finally realized that I am analyzing their teaching in the same way that I analyze my own and trying to learn more about the best way to help my students.
It is possible that I am just rationalizing to make myself feel better about how much time I spend reading these blogs.
