Most faculty are familiar with the strategy: students are allowed to bring into the exam a card or sheet of paper that they’ve prepared beforehand and that contains information they think might help them answer exam questions. I became convinced of the strategy’s value when my husband was an undergraduate. He and his engineering study buddies convened at our place the night before an exam to decide what they should put on the 4 x 6 note card they were allowed to take into a mechanical engineering course. They spent hours in heated discussion. They thought they were just figuring out what went on the card, but in fact they were sorting out, prioritizing, organizing, and integrating the content of the course. Their discussion accomplished that way more effectively than any review session I had conducted. Of course, being engineers, they decided on what they needed and then reduced the size so that when they got it on the card they needed a magnifying glass to read it.
