It goes “When a measure becomes a target, it ceases to be a good measure.” How does that work in practice?

Ever hear the term “teaching to the test”?

If the goal is to teach someone how to do multiplication, it makes sense to have a test at the end of the class to see if they can do it. However imagine if the teacher was paid based on how well the class did on the test (as a measure of how well they taught the class). If the teacher knows the questions will be what is 6×7, 11×12, and 3×4… would it make more sense for the teacher to teach all of multiplication or just teach those questions. Because the teachers goal now is not teaching multiplication, it’s getting the kids to pass the class.

Now the classes will likely get a lot of 100%s but they might not know multiplication.
