For example let me use dis: Imagine for a second that you’re teaching a math course full of fourth graders. You’ve just administered a test with 10 questions. Of those 10 questions, two questions are trivial, two are incredibly hard, and the rest are equally difficult. Now imagine that two of your students take this test and answer nine of the 10 questions correctly. The first student answers an easy question incorrectly, while the second answers a hard question incorrectly. How would you try to identify the student with higher ability?
