Descriptive evaluation of students using fuzzy approximate reasoning

TL;DR

This paper introduces a fuzzy logic-based evaluation system for students that improves fairness and reduces errors compared to traditional four-valued logic methods, with practical implementation in educational settings.

Contribution

It proposes a novel fuzzy descriptive evaluation system that replaces four-valued logic with infinite-valued fuzzy logic for more accurate student assessment.

Findings

Fuzzy evaluation provides more nuanced student assessments.

The system can be implemented via a smartphone app for ease of use.

Simulation in MATLAB validates the proposed method.

Abstract

In recent years, descriptive evaluation has been introduced as a new model for educational evaluation of Iranian students. The current descriptive evaluation method is based on four-valued logic. Assessing all students with only four values is led to a lack of relative justice and the creation of unrealistic equality. Also, the complexity of the evaluation process in the current method increases teacher errors likelihood. As a suitable solution, in this paper, a fuzzy descriptive evaluation system has been proposed. The proposed method is based on fuzzy logic, which is an infinite-valued logic and it can perform approximate reasoning on natural language propositions. By the proposed fuzzy system, student assessment is performed over the school year with infinite values instead of four values. But to eliminate the diversity of assigned values to students, at the end of the school year, the calculated values for each student will be rounded to the nearest value of the four standard values of the current descriptive evaluation system. It can be implemented easily in an appropriate smartphone app, which makes it much easier for the teachers to evaluate the evaluation process. In this paper, the evaluation process of the elementary third-grade mathematics course in Iran during the period from the beginning of the MEHR (The Seventh month of Iran) to the end of BAHMAN (The Eleventh Month of Iran) is examined by the proposed system. To evaluate the validity of this system, the proposed method has been simulated in MATLAB software.
