A powerful moment for me on Tuesday occurred when Chad asked whether we think of assessment as something done to our students or something the students are doing. I've long lamented the fact that assessment is done to students in a way that seems to give them no agency. But I didn't realize that I was assuming that there's no alternative. The idea that students themselves can do the assessment, and that we can create the appropriate tools to measure that assessment is a wonderful insight -- a genuine "aha!" moment.
