Automatic grading and how to game it

Edgenuity involves short answers graded by an algorithm, and students have already cracked it

The Verge has a story on how students are figuring out how to game automatic marking systems like Edgenuity. The story is titled, These students figured out their tests were graded by AI — and the easy way to cheat. The story describes a keyword salad approach where you just enter a list of words that the grader may be looking for. The grader doesn’t know whether what your wrote is legible or nonsense, it just looks for the right words. The students in turn get good as skimming the study materials for the keywords needed (or find lists shared by other students online.)

Perhaps we could build a tool called Edgenorance which you could feed the study materials to and it would generate the keyword list automatically. It could watch the lectures for you, do the speech recognition, then extract the relevant keywords based on the text of the question.

None of this should be surprising. Companies have been promoting algorithms that were probably word based for a while. The algorithm works if it is not understood and thus not gamed. Perhaps we will get AIs that can genuinely understand a short paragraph answer and assess it, but that will be close to an artificial general intelligence and such an AGI will change everything.
