I have been feeling guilty about not updating my blog, but was able to put it off - that is, until I read f(t) yesterday and found myself totally agreeing with her.
As a kid, I never kept a diary (I tried many times though!). In fact, I still have the first (and only) diary that I got when I was 7... it's only about a 1/3 filled and that includes through age 20! I didn't really expect much out of a blog either, nor did I ever expect to have readers or commenters. However, what I've found in the blogosphere is that this is an amazing place for reflection, collaboration, and the occasional vent.
By looking at my blogroll at the right, you can see that I follow mainly math teachers, with an occasional elementary teacher (love Mrs. Mimi!) or other subject matter teacher thrown in for their quirky sense of humor, writing style, etc. I enjoy reading the ups and downs of other classroom teachers, LOVE the WCYDWT feature on dy/dan, getting to peek anonymously into other classrooms :)
This summer I have also discovered Twitter, another tool that has been amazing for online collaboration. I follow a lot of the same people that I follow in blogs, but the feedback is what truly makes Twitter a useful tool. By posting a comment or question in 140 characters or less, you can open the lines of communication with other teachers and get almost instant responses about their policies, procedures, lesson ideas, etc. I don't think I would use Twitter much for my personal life, it has great applications professionally.
For me, this blog fills a huge gap in my teaching career. By forcing myself to descibe a situation clearly so that the reader can understand, I end up with a clearer understanding myself. This reflective nature of the blog is one of its greatest attributes.
