I want to draw a clear link here between gaming and grading. Beth Kanter isn't talking about grading; she asked for ideas on how to make measurement fun and got suggestions back like "humanize the numbers", "report the impact" and "make the report tactile" by allowing people to manipulate the data. My point is, grading should be like that as well. Instead of offering a single, final, sterile grade like "C", draw from a variety of metrics and report achievement as though you were a member of the spreadsheet appreciation society. In other words, gamify it. Draw on a variety of metrics, allow students to measure their scores against their personal bests, against each other, or against the machine, and back them up the way sports does, with statistics, measurements and analysis.
