The Role of Triangular Fuzzy Neutrosophic Set-Based QUALIFLEX in Enhancing University Dance Instruction Assessment

The evaluation of university dance teaching quality involves a multi-dimensional approach, including the achievement of teaching objectives, the scientific and innovative nature of course content, the diversity of teaching methods, instructors' professional competence, and students' participation and progress. It uses both quantitative and qualitative analysis, incorporating student feedback and classroom observation to ensure comprehensive assessment. Continuously optimizing teaching strategies, enhances students' artistic literacy and overall abilities, supporting the development of high-level dance talent. The college dance teaching quality evaluation is multiple-attribute decision-making (MADM). Recently, the QUALIFLEX method has been established to cope with MADM issues. The triangular fuzzy neutrosophic sets (TFNSs) are established as a tool for characterizing uncertain data during the college dance teaching quality evaluation. In this study, the triangular fuzzy neutrosophic number QUALIFLEX (TFNN-QUALIFLEX) method is established to solve the MADM under TFNSs. Finally, a numerical case study on college dance teaching quality evaluation is provided to validate the proposed method.
