Question 755339: Suppose you’re teaching mathematics to a class of 20 sixth grade students and at the end of a unit on
measurement, you gave a 100-point multiple-choice test on measurement concepts and skills and
your students obtained the scores shown in this class list. (Table 1) You know that students from this
school have had trouble with measurement items on the state test in previous years, and you’re
wondering whether you need to do more teaching in this area or can move on to the next topic. You
take these scores into the teachers’ lounge and ask colleagues to take a look. When they ask about
the test you explain that you designed it so that if a student gets a score of 80% or better on it, you
are really quite confident that he or she understands the concepts. When a student’s score is lower
than that, you feel there is something they still don’t understand.
One of your colleagues pulls out his calculator and shows that the mean for these scores is 80.6. “The
mean score is greater than 80. You’ve done your job. Move on! There’s lots more math to cover.” would you reteach the curriculum or leave it alone.
