The Science of Teaching Writing

I really believe that teaching writing is both an Art and a Science, and not wanting to rip off Lucy Calkins, I went for the science title (no, it wasn't for you Jason). Teaching writing is creative, not a systematic program because each writer is different. I takes investigation, data to measure, like science, because without inquiry, we're not going to get very far.
I'll try to post as often as I can, at least once per week, of the different writing lessons/activities that I've taught that I feel worked well with my 6th grade students.
I teach 6th grade in Northern Colorado, in an elementary school. We rotate kids, similar to a Junior High, so our kids get used to it before they do it next year. I'm teaching poetry right now, and next quarter I'll be teaching writing integrated with science. After that, who knows.
I'm providing inservice to two schools with another teaching friend of mine, and I help coordinate inservice with other school and teachers through the Colorado State University Writing Project.
