I am a teacher, and part of my student's grade is based on an in-class response to questions. I noticed that on some days, I was calling on the students who usually don't have the answers, and then on other days, I called on the better students.
To solve this, I produced a truly random class list for every class meeting. Now I don't have to think about who knows what, I just read the next name in the list.
