I was a grader of the AP exams at Clemson week before last. The papers reflected a mass ignorance of Euler's method, slope fields, and Riemann sums. In the case of the latter, students may have not been familiar with the word Riemann but would have done all right if they had just been asked to use the midpoint rule. Teachers need to work on these topics.
If you would like to keep up with the latest trends, join the North Carolina Association of Advanced Placement Mathematics Teachers. We publish two comprehensive newsletters each year for only $4.00. The summer newsletter which will be published in July will include the 1998 grading standards, commentary on each problem by a person who graded the problem, and other general information about the examinations.
