This would suggest that a portfolio is a means of self-expression. Students should be encouraged to show who they truly are through a portfolio.
So I was just looking at a folder of work that a seventh grader wants to use in her portfolio. She came to me asking me to "approve" of the work. "Is this good enough for my portfolio in Independent Reading?"
It wasn't easy to get her to understand that I wasn't going to give approval or disapproval, and instead I asked her in as many was as I could think of to show me how the work show us something important about her ability to "have conversations online" (as our competency states) about her reading. Or more generally, I said, "Okay, so here are three responses to short stories that you have first drafts of. You do need to finish them, and as you do, think about what you want these to show about your unique, thoughtful ways of responding to literature."
We have work to do. But Mary Diez's metaphor here reminds me of how important it is to return the power of the portfolio to the student. It's not my approval of the work that matters, it's the student's ability to recognize and articulate her own sense of why this work matters, how it shows something important about herself.
