Assessment is not a spreadsheet -- it's a conversation.
One of Mr. William's five principles is that the teacher should "share with [students] where we're going with the learning." This sounds an awful lot like the practice of "writing the objectives on the board"--a practice you have objected to. This is a subject I've wondered about (I tell the story, in the post listed below, of a time I wrote a "Learning Target" on the board and my most sophisticated students all started laughing and making fun of me). Anyway, I'm curious what you think the difference is between William's "sharing of learning intentions" (or whatever his exact phrase is) and writing objectives on the board.http://literacyinleafstrewn.blogspot.com/2012/12/visible-learning-school-reform-and-in.html
