New Approach Single Valued Neutrosophic Sets for Teaching Quality Challenges Evaluation in College Public English Broad Impacts

Abstract

Previous research on teaching quality challenges in college public English has relied on methods 
that accept vague or fuzzy inputs. Single-valued neutrosophic Sets (SVNSs) are used to handle 
uncertain or unclear expert assessments by allowing both precise and imprecise data to be 
analyzed together. This approach ensures that valuable information is not lost during the 
evaluation process.  To improve decision-making in multi-criteria decision-making (MCDM) 
problems, this study introduces a new integrated framework that combines the EDAS method 
with the MEREC method for criteria weight computation under the SVNS environment. The 
MEREC method is applied to determine the importance of each criterion, while the EDAS method 
ranks the alternatives.  A case study on evaluating teaching quality challenges in college public 
English is conducted to demonstrate the effectiveness of the proposed framework. In this study, 
three experts evaluated 11 criteria and 7 alternatives. Sensitivity analysis was also performed to 
test the stability of the rankings under different criteria weight variations. The results show that 
the ranking of alternatives remains stable, confirming the reliability of the proposed approach.
