Bravo for Evergreen's replacing grades with this kind of self-conscious reflection. I think the above account shows that its benefits occur throughout a student's course of study, that it is more than an "assessment". Having implemented something similar within particular courses, and seen similar results in terms of student awakening, I endorse their efforts wholeheartedly. Outside of such a progressive, small liberal arts environment, however, those who try this may find themselves confronted with students who have rarely, if ever, engaged in this kind of self-reflection on the trajectory of either their learning or their lives. As a result I was prompted to write an essay explaining my notion of what I was asking them to do:

Fortunately, most found it useful and often expressed sentiments akin to those related above.
