Combined Framework for Teaching Quality Evaluation of Online English Courses of Vocational Colleges Under Interval Neutrosophic Sets

The evaluation of teaching quality in vocational college English online courses is crucial. It monitors the teaching process, ensures objectives are met, and improves course quality. Flexible online evaluation methods comprehensively reflect outcomes, making a scientific evaluation system essential for quality improvement. The teaching quality evaluation of online English courses for vocational colleges is multiple-attribute group decision-making (MAGDM). Recently, the LogTODIM approach and MACONT approach was constructed to put forward MAGDM. The interval neutrosophic sets (INSs) are constructed as a tool for managing fuzzy data during the teaching quality evaluation of online English courses for vocational colleges. In this work, the interval neutrosophic number LogTODIM-MACONT (INN-LogTODIM-MACONT) approach is constructed to put forward the MAGDM under INSs. Ultimately, a numerical analysis for teaching quality evaluation of online English courses for vocational colleges is constructed to validate the proposed approach.
