I, too, would love an example of a completed assignment. Perhaps more, I would like an example of a rubric one might use.
I was perplexed by Gibb's remark along the lines of "you know you created a good test when students can't imagine how you would grade it." I sense there is something right about that, though I'm not sure what. However, I'm not sure how neatly it fits with one of the principles from the Assessment course: we must be clear with students about how they will be assessed (so they know what is required of them, so they won't be anxious, etc.). I think that principle was from the Burlew talk(s).
