In this article, the author discusses the "O" grade that is sometimes given out to students who do not complete their work. The author feels there are two issues to consider and in this article, he discusses those two issues. First, and most important, is to determine the appropriate consequence for students who fail to complete an assignment. The most common answer is to punish these students. Evidence to the contrary notwithstanding, there is an almost fanatical belief that punishment through grades will motivate students. In contrast, there are at least a few educators experimenting with the notion that the appropriate consequence for failing to complete an assignment is to require the student to complete the assignment. That is, students lose privileges--free time and unstructured class or study-hall time--and are required to complete the assignment. The price of freedom is proficiency, and students are motivated not by threats of failure but by the opportunity to earn greater freedom and discretion by completing work accurately and on time. The second issue is much more straightforward. Even if teachers want to punish the little miscreants who fail to complete our assignments--then what is the fair, appropriate, and mathematically accurate punishment?
