Abstract

The difficulties associated with translating a set of scores into letter-grades are discussed. A novel method for automating this process, the Fuzzy Grading System, is developed and compared to traditional practices. Letter-grades are recognized to be fuzzy descriptors of students´ performance. Thus, operations aimed at defining letter-grade boundaries are naturally carried out in the context of fuzzy set theory and logic. The Fuzzy Grading System utilizes students´ and instructor´s performance measures in order to modify a set of collectively approved, a priori fuzzy grades, so as to produce a “fair” mark distribution. The validity of grades is increased by compensating for factors that are not directly accessible to simpler, traditional grading methods
