what is an appropriate grade distribution in class? when i glanced over a list of potential prompts for this blog post, this question instantly caught my eye. i\u2019ve thought about it a lot, and i still don\u2019t feel i have a single, concrete answer.\u00a0 on one hand, like most students at vanderbilt, i spent the majority of my high school career making as and bs. the current college admissions system stresses the importance of the grade itself.\u00a0 as a result, students have grown accustomed to desiring a high mark, regardless of what that grade actually signifies. with this frame of reference, a good grade distribution can be thought of, to some degree, as one that gives a large amount of as. however, as most students are fully aware, this is not actually a desirable outcome.\u00a0 it may make many people happy in the short run, but it typically ends up doing more harm than good.<\/p>\n

ideally, i believe that grades should be a reflection of a mastery of the material of the class. as such, i don\u2019t feel like grade distributions should even be a consideration for a professor. tests are designed to gauge the amount of knowledge obtained by the student (or the ability to analyze and problem solve), and inherent in this concept is the idea that there is a certain level of competence that the professor expects. if a student reaches this level, they have demonstrated that they have learned what is necessary from the course and deserve an a. conversely, a lower grade is expected if the student does not reach that level. therefore, grades are entirely dependent on where the professor sets that level of competence. if the bar is set low and all of the students excel, then everyone deserves an a, because the entire class learned exactly what they professor hoped they would learn. the same should be true when a professor sets the bar for competence too high. if no one reaches that level, then, theoretically, no one should receive an a.<\/p>\n

the problem with this approach is the need to use grades as a means of comparing students\u2019 academic success. if two students learn the exact same material, but one takes a test written by a professor who expects a lot more out of his students, then their grades won\u2019t reflect the fact that both students essentially have the same knowledge. i\u2019ve been in several classes where the average grade has been in the low 50\u2019s. this should technically mean that the vast majority of the class only understood roughly 50 percent of the material, and the grades should reflect that. luckily (for the students in that class at least), the concept of \u201cgrading on a curve\u201d is frequently used to account for the fact that different professors expect different things from students. with this philosophy, grade distribution should be a consideration for teachers.\u00a0 as an engineer, i can appreciate the value and importance of statistics, and therefore i tend to believe that the typical gaussian (normal) distribution of grades is the most fair. a small percentage of students, those that receive the highest marks, deserve the a\u2019s, while the majority of the class should receive grades in the low b\/high c regions. therefore, the \u201cbest\u201d students receive the best grades, regardless of how difficult a particular test or professor might be, allowing this grade distribution to remove the variability between professors.<\/p>\n

even after writing all of this, i still don\u2019t know what i actually think a fair grade distribution is. it really all boils down to the role of grades, and whether they should be used as an absolute means of quantifying the amount learned or a relative scale used to separate students. and that is not a question easily answered.<\/p>\n
