I love that this has finally come full-circle. I remember early scan-tron bubble sheets that you would record test answers on, then all the sheets were fed into a machine and it output the scores for the whole class.<p>Later on, there were web-based automatic graders, that, for example, would accept "3.0" as a correct answer, but reject "3" as incorrect.<p>This is just the natural recoil to a system that treats young human beings as automatons.
