The one 26 wrong answer is usually made blatantly obvious by its absurdity. We believe that students will
be more apt to answer honestly and not try to look up answers before they take the quiz with
this format. Incidentally, the questions that require one right answer are straightforward and the
material that contains the necessary information to answer correctly is easily accessible during
the quiz. Statistically, the amount of time students take on the pretests is very low, usually
averaging less than 10 minutes. For the Moon phases lesson, we chose to inventory four of the
more common ideas about what causes the phases. In addition, we chose to inventory students=
ideas about when one can see the moon and whether or not the phases have anything to do with
the times of day or night that the moon is visible.
