I'm going to record my thoughts about the process of analyzing my student's writing for my personal narrative unit. First, I don't think it was a completely unsupported assessment. I did this with some instruction but little assistance during my first week of writing workshop.
I think it is important to record the process to understand the amount of thinking and time it takes for teachers. That way, when other teachers start the process, I am able to assist them with learning about formative assessment and the power in setting curriculum that meets the needs of the learners instead of going through the units pacing within a "one size fits all approach."
To begin, looking over the stages of development developed by Lucy Calkins and recently published in the Writing Pathways:Performance Assessments and Learning Progressions k-5 is completely overwhelming. I can't imagine the implications for teachers. This text alone could be a book study for a staff for a whole year!
