Abstract

The purposes of the study were to try to build a structure model of a fuzzy educational grading system and propose an algorithm with it. We also discussed a method to build the membership functions of several linguistic values with different weights. Moreover, this study was prepared not only to assist teachers, in a practical setting, aggregating different test scores in order to produce a single score or grade for student, but also to help teachers deciding whether to revise an instructional procedure for their students. Finally, we would compare the traditional educational grading system with the fuzzy educational grading system and point out the advantages of using the latter system.

    This shows that the use of linguistic terms makes experts judgment more reliable and informative for decision making. The linguistic approach is an approximate technique which can be used in different fields, such as, marketing [39], clinical diagnosis [7], decision making [8], risk in software development [17], education [16], technology transfer strategy selection [4], information retrieval [2], etc. However, the implementation of linguistic approaches has some serious limitation due to the fact that these approaches assess a linguistic variable by using a single or simple linguistic terms.

    However, the drawbacks of the methods presented in [14,17,19–21] are that they cannot deal with the fuzziness in the process of students’ evaluation. In recent years, some methods [3–5,7–9,11–13,16,18,22–25] have been presented for students’ evaluation based on fuzzy sets [28] to deal with the fuzziness in the process of students’ evaluation. In [11], Cheng and Yang presented a method using fuzzy sets in education grading systems to solve the subjective judging problems of teachers.
